I can't tell what you want from your question. I don't see any reference to your 3rd table.
Why don't you try writing up working example at http://sqlfiddle.com/ then add a link to your question?

Hmm...both of my ALT keys show up when I run the example code at my link.
Did you know that when you RDP to a box only the left ALT key works on the remote box?
It's interesting that you're seeing that behavior locally.

ok, well sorry to hear about your keyboard problem, but at least you were able to discover what the root cause was. Thanks for posting back and mentioning that you found the problem. Good luck to you.

If you tried my example and it still didn't work then either:
1. it is your browser -- which browser are you using?
2. it is your keyboard

Good luck,

We posted at the same time. :) Took me a minute to see that the from was missing.

Glad you got it working. Way to stick to it and not give up until you get it done. 👍🏽

Are you looking for something like:

let allValues = ["first","second","third","fourth"];
allValues.map(val => console.log(`I like ${val}`))
OUTPUT
I like first
I like second
I like third
I like fourth
Or if you're trying to replace multiple values in the one string with multiple values from an array, it becomes a bit more imperative-style programming -- step-by-step.
In that case you'd have to 1) get the value from the string 1,2,3 etc then get the target value from the array, then replace the value in the original string with that value.

The addition of the / means replace all of the (left bracket, followed by 1) [1
Then there is the | (or) (right bracket) \]

So in natural language it would be something like:
Replace All left bracket followed by 1
or any right bracket ] with an empty char

what does text variable look like?

This line seems suspect: temp_df = pd.read_html(base_URL)[2]
You're indexing off the HTML that comes back into the 2nd element??
What if it fails? What would temp_df value be when it hits the code that you seem to be indicating that fails?
results.append(temp_df,

It's a long time since this has been posted, but I've been thru this problem also (and had to entirely reset my app & lost my users). This was about to happen again, as AndroidStudio was telling me that the keystore was tampered with or I had wrong password. I knew it wasn't wrong password because it is stored in a password manager.
I stumbled upon a fix however & wrote it up at: https://stackoverflow.com/questions/72176501/why-does-androidstudio-fail-when-building-signed-apk-for-google-play-says-bad-p

The thing that fixed it was running the command-line keytool app like:
$ keytool -list -keystore 'fakeNmae.jks' -storepass fake-password-same-one-i-used-in-android-studio

except, of course, using the real password & keystore file name.
After that AndroidStudio built the signed APK & I couldn't believe it.

This may help -- It mentions the command you're wanting to run: https://stackoverflow.com/questions/62034545/dockerfile-how-to-set-apt-mirror-based-on-the-ubuntu-release

It looks like maybe you need to first run:
$ apt-get update && apt-get install -y lsb-release

Additional details....
If you just want to try my template out. then...
1) clone it
2) $ npm install
3) $ npm start
You will see the proper icon -- the temporary one that the template uses.

If you do a $ npm run dist it will generate the target exe for your current platform. If you go down into that /dist directory and run the target it will probably not show the icon.
It wants the ICON in the same directory where the EXE starts from.
So if you take the EXE and the app.png and put them in the same directory and then run the app you will see the icon.

I noticed a couple of things about the icon. 1) If I run two copies of my app the first one will display the icon and the other one will display the generic electronjs icon. 2) Your real icon may only display when you run the _real_ copy (not the dev version). Do a build and then try running the deployed version you may see the proper icon.

Also, I struggled with this and with building for all platforms (win,linux, mac) so much I finally found a really nice electron builder and I created a complete project template that even sets up the icon properly.
I created a public github for it at: https://github.com/raddevus/electron-template

Please take a look at that. Clone it, build and see if you see that icon.
There are complete set of instructions there with the project.
let me know if it helps.

Actually, I can't remember why. I just remember working through this and it was the only way I could get it to finally work. My solution may be related to deploying my app on https://snapcraft.io/ also. I can't remember now.
Good luck.

Have you tried it without the code that is in the catch{}?
Remove the async call from the catch and try it again.
I believe the error is occurring because it's attempting to add the same module more than once. and that is possibly happening because it throws an exception and calls the async call.
Also, try debugging / stepping over each line and see what happens.

I'm wondering if Python has updated on your computer recently and now VS Code doesn't know how to get to the proper EXE?
Were you by chance, using Python 2.x before?
has Python 3.x been recently installed?
or has Python just been updated and now VS Code can't find it?

I’m saying it is a concept, an idea, a classification, a model or way of thinking about functionality that is grouped together. That’s it. You can say , “I downloaded a library” but you really downloaded DLLs that contain functionality that has been grouped together. A library is really only conceptual not physical.

Library is probably more conceptual. You may have something like the .NET library which is made up of one or more packages (physical downloadable DLLs).
So a library is a broad term that envelops the conceptual idea of one or more packages that solve a specific problem.
A Graphics Library provides functionality that helps you do drawing in your app (lines, rectangles, etc). And to use that library you download the physical DLLs (aka Assemblies in .NET) which are generally known as packages.
and they are known as packages more now because of NPM (node package manager) and nuget (.NET package manager).

Here's a very short snippet of code at codepen that uses some of your concepts:
https://codepen.io/raddevus/pen/KKqwRPa

Add your html & code to something like codepen.io (click the Start Coding button on the left side & add your code). Save the code and link then let us know so we can see the entire code sample. Then we may be able to help you.

👍🏽😆

You better hope The Delphi people don't read this. They'll hound you to the ends of the earth. 🤓😆 (Psst...Delphi is Pascal)

Time-complexity would be O(n^2) because you iterate through n items once in the foreach loop and then once in the while loop.
The print part isn't really a part of the algorithm and should actually be removed into a separate function and shouldn't really be counted as an iteration through the items, since it is just for output.

I've added new info to my original answer. Hope it helps. :)

Try...
return null;
instead of the...
return View()
I think you may be pleasantly surprised. If this works, you can determine some way to return null when you want.

Did you set up the SMTP options (outgoing server) for the outgoing email?
--smtp-server=<host>
--smtp-server-port=<port>

I tried your code. It failed upon attempting to enter the two player names. I wanted to see it run so I altered the case 1 statement to include newGame() and the game started without a player 2 name anyways.
I played an entire game and I'm impressed with this example program in C. It's quite nice and amazing that it actually determines a winner.
Also... to save your data you should just save each value the user enters into a CSV (comma separated values) file.

Also, the value is an _attribute_ of the XML tag. I'm assuming you're attempting to get the value of the attribute which is named value.
The value of a tag would be something like <title>The Bering Sea: A Book About Sea Life </title> It's what is between the tags. An attribute value is different.

Really great and interesting answer. Thanks

I've often wondered about this also and this is a great question. Thanks for asking it here where there are people who can offer some answers. Really great. Thanks

Great points and resources. thanks

check out part 2 (added to my answer above) - what you're wanting to know how to do is set up the XMLHTTPRequest XHR so you can post to the controller, it was in part 2 of my articles: https://www.codeproject.com/Articles/5268710/NET-Core-Web-API-The-Least-You-Need-To-Know-Part-2

Post a snippet of your code that you have tried. You marked this as Java but I'm guessing (from the names of the controls) that it is actually Java on the Android application dev platform, right? Explaining how to pass values like this takes a longer explanation.
Mention all important details like that so the person with the correct expertise can help you. Here's a book, only $2.99 that will help you understand how to pass values in Android: https://amzn.to/3fd2TsC

create a specific span or div element with an id="yourId", then use query selector to select the item and add the style to the specific item.
Also, modern element selector is document.querySelector("#yourId") for single and document.querySelectorAll(".classItem") -- returns collection of elements (id selector can be used with querySelectorAll() also.

I understood that, but I've seen this occur when the control isn't properly "registered" to Visual Studio. I have had the problem in the past and adding it into the Toolbox has resolved it for me in the designer.
The process of doing that somehow "registers" the control and Visual Studio can render the control. Did you try it? Did you restart VSTudio? Did it not work?

Yes, looks good. Now the month1 variable has scope that is larger than just the try block.

I think you are saying that you have a 1 to Many relationship from User to Quest.
1 user can have 1 to many quests.
In this case you can create a simple table that contains only two columns:
User_id, Quest_id

Then you simply put your data in there and use it for the join later.
User_id, Quest_id
1 , 1
1 , 3
1 , 4
1 , 5
2, 3
3, 1
3, 2

You see, some users have many quests(userid 1) and others (userid 2) only have 1.

This is interesting, because I tried it with a local extra spreadsheet file and it failed too. It is a security thing. You need to add a Module and then add your code to that module and you'll be able to run it.
Here's how you add a new module ---> https://i.stack.imgur.com/OTELN.png
I've actually solved this another time and you can see my answer (which displays that image) at StackOverflow: https://stackoverflow.com/questions/33741488/cannot-run-the-macro/42773999#42773999
My answer is NOT the official answer but has been upvoted more than the official. :)
This will get you to the solution. In the end, the problem is really because of newer security features of Excel -- it doesn't want other files to be opened unless the code is in the protected module area. Please let me know if that works.

Very good points. Was attempting to provide basic "test" solution with string concatenation.

Oh, also, I see that it looks as if WPF doesn't implement NotifyIcon according to this: https://stackoverflow.com/questions/17674761/can-i-use-notifyicon-in-wpf
But there is a project here on CP that may work you thru it: https://www.codeproject.com/Articles/36468/WPF-NotifyIcon

I know that there is no requirement under WinForms and using NotifyIcon so it is probably the same under WPF. Here's an example I just fired up and got running in LINQPad (Linqpad.net) and it displayed the notifyicon in the tray even though I'm not an admin on my machine : https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.notifyicon.-ctor?view=netframework-4.8#System_Windows_Forms_NotifyIcon__ctor

I have waited so long to be a hero, but I knew I'd make it one day. :D Glad it helped.

What is on line 138 of Cusinfo.aspx.cs?
C:\Users\Zeeyana\source\repos\Money Changer\Money Changer\Cusinfo.aspx.cs:138

That is the thing that the runtime thinks is null.

Check out the selected answer on this SO: https://stackoverflow.com/questions/6328713/urls-with-slash-in-parameter

I don't believe UrlEncode will work here, since it won't encode the slash (/). if you open your browser tools F12 and type the following in the console you'll see you get the same string (non-encoded): encodeURI("B0015/A") // javascript's version of url encode.
I tried the other one also and it does the same -- does not encode the slash:
Console.WriteLine(Uri.EscapeUriString("B0015/A"));
If you want to try base64 encoding as javascript you can try:
btoa("B0015/A") // in console

Send it in as a querystring variable, then extract it.
build your URL that you will submit:
www.yourthing.com/thing/?divCount=195

<?php
echo $_GET['divCount']; //Output: 195
?>



Your next question will be: HOw do I post the URL?
Check out this --> https://stackoverflow.com/questions/5647461/how-do-i-send-a-post-request-with-php

Yeah, since it's a winform app try using just the DataSource, DisplayMember and ValueMember properties on that clientDropDown and then it may work -- depending upon a number of other things. it can be a bit tricky getting it just right.

Yes, I think that is the cause. I don't have a lot of info to help you fix that though.
Is this a WPF app? I thought it was WinForms.
If it is WPF there is a very good explanation here at CP about this databinding like you are attempting: https://www.codeproject.com/Articles/671544/Understanding-SelectedValue-SelectedValuePath-Sele

it's short and may help.

Since it works with the hard-coded ID value (a known integer) then the problem is probably with how the value is being retrieved from the droplist. Have you set DisplayMember and ValueMember of the droplist (combobox, or whatever that is) properly?
For example of what I mean see:
https://stackoverflow.com/questions/9521980/combobox-valuemember-and-displaymember

It's difficult to determine what is going on. But I do have two suggestions (maybe you've already tried them?).
1) replace the SelectedValue with a hard-coded value (possibly one you know is valid) and try running.
change => { "@ClientId", ClientDropDown.SelectedValue }
to => { "@ClientId", 5 }

2) Run in debug mode step into LoadDateDropDown and press F11 on each line (step into) to determine exactly where the code is failing.

Fantastic! I was just reading this and I googled for a solution and the answer at https://stackoverflow.com/questions/3159213/how-do-i-create-a-simple-web-server-using-wcf-without-the-servicehost-class is really great. You can run that example in LINQPad.net (https://www.linqpad.net) with the following using statements:
System.Runtime.Serialization, System.ServiceModel.Channels, System.ServiceModel, System.ServiceModel.Web

If you successfully create a separate thread it will not be allowed to write to the UI since the UI-thread (main thread) is managing that work too. In most instances if you get it to do so your app will crash. However, I believe you are saying you are attempting to do a delegate for that exact reason.
Unfortunately, you're probably not going to find a lot about it in VB.NET resources, but here is a fantastic write-up that should help you understand these concepts better: http://www.albahari.com/threading/ -- This is the original author of C# In A Nutshell O'Reilly book. It'll help you get through the challenges if you ignore that it is C# centric.

You get a full column of blue because it iterates through every row in the datagridview and sets it blue : dgvSODetail.Rows[i].Cells[3].Style.BackColor = Color.Blue

Rows[i].Cells[3] is every row since i changes.

sizeof(List) returns the number of bytes the entire list takes in memory.
sizeof(List[0]) returns the number of bytes one element take in memory.
If Int is Int32 then each one takes 4 bytes.
So if you have 4 elements in your list then sizeof(List) returns 16 bytes.
And, of course, sizeof(List[0]) returns 4.
16 / 4 = 4
so while i < 4 (0 - 3) the for loop will execute.

It's no problem. Thanks. :)

Wait. Was I down-voted for answering an old question or because my answer was bad? Inquiring minds want to know. Actually, I don't really care, just hoping these comments are posting to your email. hahahhaaaaaa!!! Lighten up, Francis.

Haha! "A good answer never grows old".* ~Confucious
Actually, right after I submitted the answer I was like, "wait, when was that question asked?" and I noticed how old it was.
The question bubbled up on the right side of the questions page and I answered it before I noticed that it was old.
I often do lame stuff so I figured leave this additional lame thing in the history record. :)

*Totally fabricated quote, but it sounds good here. :)

Okay, easy enough, I updated the script -- updated my entry to show the code. You can go to the jsbin and see the final code. You'll need to make sure you close the tab you had it previously loaded on and then open the link in a new tab in your browser to insure a refresh.

i updated it with the addt'l code. Tried to get it done before comment but was late. :)

But the question was about PHP, so... :) Which from my understanding is a version of the Java ASCII Unicode standard library. xD

You definitely got me. Haha :)

oh, no sorry, I meant the technology. I totally understand that others do not necessarily speak English as their first language. I wish I could read/write/understand another language well enough to ask tech questions in that language. THe original question just sounded interesting to me because of the encryption of an image. Nothing more. Thanks

I was actually finding humor in the original question because it was basically a jumble of sentences. I'm still not sure what the original question was.
Zipping with a password sounds good.

But if I get your password will it still be secure? Will image still be encrypted? Sounds like a single point of failure to me.



Please, please, please know that everything I've just said it meant as comic relief. Also, please note that if you cannot understand this humor, it is only because you haven't applied the proper decryption algorithm. Try ROT-13 first and other super-secure algos first. :D

That is interesting and could be because mine is the same program running multiple times --- meaning the random value is seeded the same every time it is run. I will add the loop to mine just to see what it does.

Mine is also compiled with g++ under Debian but since this is all standard library stuff that shouldn't matter.

EDIT
Yep that's it. I added the for loop to call rand() ten times and I get pseudo-random list of values.
2 1 2 2 2 2 1 1 2 2
However, every time I run it I get that same list of 10 values, of course.

And, of course if I add the call to srand() then every time I run the program I get a more random list of 10 values.

Here's my final code:

#include <stdlib.h>
#include <iostream>
using namespace std;
int main(){
srand(time(NULL));
int random_number = (rand() % 2) + 1;
for (int i = 0; i< 10;i++){
cout << random_number << " " ;
random_number = (rand()%2)+1;
}
cout << endl;

}

I just compiled that and ran it about 10 times and I got 2 every time.
I put the program in a shell script and called it a number of times and still got 2 every time.
Does the rand() call need to be seeded first or something?
Just curious

Here's my code
#include <stdlib.h>
#include <iostream>
using namespace std;
int main(){
int random_number = (rand() % 2) + 1;
cout << random_number <<endl;
}

EDIT
I added the following line of code before the call to rand() and it seems to generate 1 as the output now too.
srand(time(NULL));

I know. I thought the same thing. Funny, right? :)

I just tried that, but unfortunately, that doesn't quite get it. In this case you cannot break on JavaScript lines (no debug available). I do have a web.config that sets debug mode to be true and in the Studio editor I've set a breakpoint and Studio looks as if it will hit the breakpoint (it's red in the UI) but it never does. Also, obviously, in this case the web.config is basically ignored because the ASP.NET engine isn't really running since my app is just html, js, css.
Also, as an FYI I did add all files successfully to the empty project and Studio recognizes them all.

Also, I'm not sure how to get the JS minification to run outside of the call that an MVC project makes in the global.asax, so I don't get minification either.

Also, @RyanDev, did you down-vote the question? That doesn't seem very helpful of you, if you did.

Later after my last comment and attempting to discuss...Another down-vote without explanation. It's too bad you guys couldn't actually create a real community of discussion. It's too bad CP allows this behavior.
I am open to discussion and changing my question.
Good luck.

Edit 3
Yes, I'm going to keep editing this and responding to your down-votes, because it is fun. You trolls are so dim-witted. I think it is fantastically hilarious. Keep 'em coming bro.
When you down-vote a question on the community, you are actually down-voting yourself and the community.
And you live in that community. Hilarious.

Reason for my vote of 5 \n Interesting tip and interesting thinking to get to the result. Thanks for sharing.
