Be aware that the ValidateProperty method might do some modifications on values before the are transferred to _selectedModel. You are executing your code on the 'value', are you sure you want to do that? Is it not that you want to execute your code on '_selectedModel' ?

And actually your code will execute everytime the value of SelectedModel will be set and not be null. This is somewhat different than it calling your code whenever the property is changed.

And yes, you might be better off creating a new handler responding to the PropertyChanged event.

Changing propertynames? NAFAIK. But, maybe if you tell us a bit more about why you would like to have this ability, we can help you find a suitable way to do just that.

Christiaan van Bergen 10-Apr-18 5:25am View

That sounds like a complete new question. Please ask a new one and supply the necessary code and error message.

How long would you like an allocation to last? In other words: if user X sees the first 4 rows, but doesn't process them, how long before another user can see them and be able to process them?

Christiaan van Bergen 5-Apr-18 4:25am View

You need to keep track of who read and who processed what. Show us your attempt in the stored procedure. What approach did you try?

Are the CheckBoxes identifiable by Name or Text like "document" or "picture"? You now have a connection only in your code between the magic string "document" and a CheckBox11. Making it hard to not use this kind of elaborate coding.

Christiaan van Bergen 4-Apr-18 18:53pm View

Yep, I missed that ) one too :-(

Yeah, but your mysqld is only listening to localhost:3306 . Compare that to the entry of your apache webserver. That one is listening to all ip addresses on port 80.

Christiaan van Bergen 4-Apr-18 18:05pm View

So everything works, but remote. Any other firewall or netfilter running on the pi? Check the running processes. Run a check on the open ports and programs:
$ netstat --tcp --listening --programs --numeric

Have you used the "flush privileges;" for the changes to take effect?

Christiaan van Bergen 4-Apr-18 17:13pm View

No, that's right. Because you need to do something with the actual message you're getting. Again, look at the example. It says: var msg = mq.Receive();
So do something with the message.

Christiaan van Bergen 4-Apr-18 16:34pm View

You are not implementing the code I showed you. In your OnStart method use mq.Receive(), I also explained why you should use that method. Try it, if it still doesn't work, we'll take it from there.

Christiaan van Bergen 4-Apr-18 16:04pm View

Please do not repost a question you asked earlier..(https://www.codeproject.com/Questions/1235440/Windows-service-receiving-MSMQ-message-only-first)

Christiaan van Bergen 4-Apr-18 15:53pm View

Have a while-loop around it, otherwise it will still not continue listening after the message has been processed.

Christiaan van Bergen 4-Apr-18 15:32pm View

Please, show us some markup code in your question.

Christiaan van Bergen 4-Apr-18 14:51pm View

Sorry, I cannot advise you on which one to use. Look at the marketplace (https://elements.heroku.com/addons/#data-stores). Ask a new question here on CP, what a good (beginners) alternative would be. Good luck.

Christiaan van Bergen 4-Apr-18 2:50am View

Can you show us the stack trace? It appears you are running code on application exit.

Christiaan van Bergen 3-Apr-18 18:29pm View

I don't think it has to do with WriteAllText. You have a config.txt file with only 5 lines. But you are trying to read lines 7 and 8. Really, I think that's your issue with this code. It is the line: var trimmedCD = lines[6].TrimStart(trimConfigDirectory.ToCharArray());

Christiaan van Bergen 3-Apr-18 16:06pm View

The error: "System.IndexOutOfRangeException: Index was outside the bounds of the array" lets me believe that that are not sufficient lines in your config.txt file. Because, without checking the amount of lines, you are trying to access the lines in the array. Could you check that, or maybe even share the contents of that config.txt file?

Christiaan van Bergen 3-Apr-18 15:28pm View

Thx, for the tip!

Christiaan van Bergen 3-Apr-18 14:50pm View

Can you explain what kind of encryption you are using? What is behind the method encrypt(plain, K)? Can you show us some code?

Christiaan van Bergen 3-Apr-18 14:36pm View

Yes, it appears so, but I was confused by the '-' (minus characters) in the sample and the two commas in the last line. So, I thought the OP might mean columns per character. But hey, your example should help <<thumbsup>>

Christiaan van Bergen 3-Apr-18 14:28pm View

Please remove this question, it is an exact duplicate of your other question.

Christiaan van Bergen 3-Apr-18 14:04pm View

That is of course when the text file is space delimited . Maybe splitting this one per character?

Christiaan van Bergen 3-Apr-18 13:30pm View

Try to make a connection with that address and port via another way. Maybe telnet?

Christiaan van Bergen 3-Apr-18 12:18pm View

Right, this number checks out. It IS 10 digits. Make it nine digits and it will fail....of course. Could it be that you have some spaces around your input? Try a .Trim() statement on your input.

Christiaan van Bergen 3-Apr-18 12:09pm View

Show me the number you want to check.

Christiaan van Bergen 3-Apr-18 11:59am View

I cannot really tell why, but I can imagine that the gets a moment without data and therefor resets to a smaller size, making the scrollbar jump back. Maybe if you define the dimensions of that div, it will stay.

Christiaan van Bergen 3-Apr-18 8:48am View

The enddate is +1 month to the startdate (making it in this case 01 march). Because of this the while loop will work. The first check inside the while-loop is to see if the day-number is an odd number. We do this by calculating the modulo of 2 (the remainder of an odd number is always '1'). If it is odd, we display the date as you requested it. Last thing we do in the while-loop is increasing the $startdate with +1 day.
You can read up on modulo here: http://php.net/manual/en/internals2.opcodes.mod.php

Christiaan van Bergen 3-Apr-18 7:58am View

Put the function in your code file, and change this line:
$salad = array_iunique(array_merge($veggies ,$fruits));
It is now using 'array_iunique' instead of 'array_unique'.

Christiaan van Bergen 3-Apr-18 7:50am View

I updated my answer.

Christiaan van Bergen 3-Apr-18 5:56am View

You're welcome

Christiaan van Bergen 3-Apr-18 5:43am View

Blunt way would be to show the affected rows in a MessageBox. Change all your ExecuteNonQuery() statements into something like: MsgBox("query1 rows: " + query1.ExecuteNonQuery())
Or put the result of the ExecuteNonQuery() in a variable and watch it while debugging.

Christiaan van Bergen 3-Apr-18 5:15am View

So no exceptions are thrown? Okay, you are working with update statements, if no records are updated, then there was nothing to update. Use the result from the query.ExecuteNonQuery() to determine how many rows were updated.

Christiaan van Bergen 3-Apr-18 4:25am View

This could be because you have missed some Environment Variables. Could you please check your %ANDROID_HOME% variable and which Android paths you've got in your PATH setting?

Christiaan van Bergen 2-Apr-18 10:20am View

Thx for the heads up, this is the trouble with writing code in textboxes and not in anything where you can check it. I just updated the answer and added a link to codepad.org where you can run the code.

Christiaan van Bergen 2-Apr-18 8:48am View

Dude, really? http://lmgtfy.com/?q=count(1)+and+count(*)

Christiaan van Bergen 2-Apr-18 8:44am View

There you go, I changed my answer. (Also I took the liberty to suggest another function name, you are no longer looking for a Value)

Christiaan van Bergen 2-Apr-18 8:35am View

So I see that you changed the function call as well. So you want to remove all key-value elements with the key "first_name"? Regardless of the actual value?

Christiaan van Bergen 2-Apr-18 8:32am View

What? Then why do you state your question as : "i want to delete the id from the all sub-array." ? This makes no sense.
Please improve your question!

Christiaan van Bergen 2-Apr-18 3:57am View

Why is the Bootstrap Tooltip not working for you? Is it because of styling? Or is it because....?
Please elaborate on that. Specify what kind of tooltip you need.

Christiaan van Bergen 1-Apr-18 6:28am View

Could you please tell us what exactly is not working? Please use the 'improve question' to add maybe some errors/exceptions you are getting.

Christiaan van Bergen 1-Apr-18 6:11am View

Does any php file work on your apache server? If you haven't tried it yet, create a new file and enter some fool proof code into it (https://www.w3schools.com/php/showphp.asp?filename=demo_syntax) and see if that works. If not, check your apache setup.

Okay, so you're giving me a php error while you're asking a question about javascript.
If it all works, as you say, when you remove the single quotes....then the solution must be: remove the single quotes :-|
But....the error states the solution, doesn't it. It says that 'mysqli_error()' expects a parameter. So maybe you should let Line 15 read something like:
mysqli_query($con,$ins_query) or die(mysqli_error($con));

Christiaan van Bergen 1-Apr-18 5:25am View

You are talking about an error, tell us what error.
But I think it could originate from this piece of code: (form.id.value.length ? form.id.value : "not specified")
form.id.value.length itself is not a boolean.
You probably meant: form.id.value.length>0

I think @Eric is right. The line :

images.Images.Add(row["picture"].ToString(), new Bitmap(image_stream));

will add the images in the collection with the same key, therefor only one ListItem will match with an image and display it.

It's quite unfortunate that the ImageList.ImageCollection.Add method does not throw a DuplicateKeyException, otherwise you would have found this one sooner.

Christiaan van Bergen 29-Mar-18 5:43am View

Dude, how about some code formatting? Makes it that much more readable ;-)

Christiaan van Bergen 29-Mar-18 4:59am View

You mean you want to iterate over some data rows to create a table in your PDF?
Could you expand your question with a sample/mockup of the desired output?
