Re: How to load a website by clicking an Item in a ListView

There is a web broswer control that you can add to your form. If you are using .net 2.0 you can use the WebBrowser control.

private WebBrowser webBrowser1;

this.webBrowser1.Navigate("http://www.microsoft.com");

There is also a control in .net 1.1. Let me know if you are interested in that one.

Hope that helps.

Hello Ben,

Thanx for your help and all the information. I think I am going to use the WebBrowser control available in NET 2.

I was wondering for if you do recal the control available in NET 1.1 Framework from top of your help just for the information so at least I know about it?

Once again, thank you very much and have a great day.

how to get to page4 of a tab control?

9-Mar-07 2:26

It is called AxSHDocVw.AxWebBrowser. It is pretty similar to the .net 2.0 one, but it is an activeX control.

Hope that helps.

Hello everyone,

I have a windows application with a tabControl. The tabControl has got 4 pages. I have a click event which I would like as the result the 4th page of my tabControl with index of "Zero" to be appeared just as if I have clicked on the Tab of the 4th page. Currently I can only get into the first page of the cabControl using the following code:

this.tabControl1.SelectedIndex = 0;

Could you tell me how I can make it jump to the page4 of the tab control?

Thank you so much for your help and have a great day.

It is a zero based index. So page four would be 3:
this.tabControl1.SelectedIndex = 3;

I’m using webbrowser control in an application I’m developing. It works great accept the view will not update while I’m executing my application. When my application halts the web page imminently updates.

I tried using Application.DoEvents(). It worked with a stand-alone application, but when I integrated into my main application, it caused my code to re-enter at the call point to the webbrowser method. I have tried hard to get it to work without success.

So is there are command or set of C# commands to get a webbrowser object to continue? Paint? Generally update while I’m working? Without DoEvents?

Hi Glenn,

Why not try to put the Webpage loading code which sould be something like

this.BrowerControl.Naligate("https://test.test.com")

in the different thread.

Making a text file tabular

I need to create a text file that will be tabular. I am not sure on how to accomplish this. I am attaching an example of the output file. You will see what I am talking about and what I am trying to accomplish.
I am using StreamWriter.Writeline(text) at the moment.
Could someone point me in the right direction?
Dang no attachments. Here is the file output:

<br />
St# Cash     Check     Credit<br />
1   5543.66  416.67    681.86<br />
2   2763.00  316.62    293.65<br />
3   3097.31  344.00    194.81<br />
4   2099.60  301.80    243.10<br />
5   2935.00  797.51    367.87<br />
6   2203.00  361.31    647.81<br />
7   6245.29  0    300.77<br />

(The message builder is ignoring spaces....)
As you can a 0 goofs it up, and when St# becomes 2 digits that pushes the whole row out one more space to the right.
And here's the actual code:
strTextLine = read["IncStoreNum"] + " " + read["IncCash"] + " " + read["IncCheck"] + " " + read["IncCC"];
w.WriteLine(strTextLine);

Thanx in advance!

C# has some nice pading functions, so I guess would suggestion pad some spaces to a set width.

So the code is like var.ToString().PadLeft(4) for the St# column unless you are planning on going over 9999 then pad 5 or whatever. You get the idea.

Hope that helps.

You could use something like

String.Format("{0,3 Big Grin | :-D

}", read["IncCash"].ToString());

only two letters away from being an asset

Exception - Cannot execute program csc.exe - ExecWaitWithCaptureUnimpersonated()

Troops,

We have a Windows Forms C# app that is getting the following error on startup. Only one user is having this issue in our new release... rolling back to the previous version works fine. I skipped over some of the stack trace.

An exception occurred

Cannot executa a program. ...\v1.1.4322\csc.exe ...
... ... \Temp\mmjry42r.cmdline

at System.CodeDom.Compiler.Executor.ExecWaitWithCaptureUnimpersonated( ... )
...
...
at System.Xml.Serialization.Compiler.Compile()
...
Cng.Tlc.LoggingService.LoggingService..ctor()
...

This happens right upon startup when it runs Main() and builds all the controls, including a web service class used for logging data about our application. This LoggingService is being established as it goes thru the stack trace above.

This user does have MSXML 4 SP2 installed on their machine and the other users at that location do not. However, I have that same SP on my machine and I'm fine.

We tried uninstalling the .Net Framework, reinstalling and there's no change. I don't see much on this topic... others are related to .ASP and IIS from what I've seen.

Any ideas?

Thanks,

Stretch

System.Net.Mail, anyway to process the incoming mailbox

Hi,

I send emails using the SmtpClient of namespace System.Net.Mail ...
Is there a way to see if the mailmessage was received or an non-delivered message
was sent back to me?

That is, process a mailbox from C# code supplied with credentials ?

The only way i know know is to use my mozilla thunderbird client to receive non-delivered mails
and that's 2-3 steps more than i want to use.. I want this included in my program!

Are there anyone that knows a way to see if non-delivered messages are sent back to my mailbox using any namespace?

Thanks from Daniel, Sweden.

It would be easier to view the mails on the mail server via imap or pop and search the texts for key text. The returned text is always different dependant on the server or smtp server that rejects it.

Hi all,

I'm not sure if that is the write word

i want to have a range of charters ( like some ones name)

and be able to go through every possiblity of each Charter

I am trying to write code that will go through each

a
b
c
aa
ab
ac
aaa
aab
aac
aba
abb
abc
aca

and so on

but only with the Char I parse into a string

Anyone got any ideas?

Google necklace generating algorithms. Personally I like n-ary trees for this type of algorithm where the data structure itself generates the necklace. Check out my bridges of konigsburg article to steal an tree structure that will do it.

Put the characters into an array and then make all the indexe permutations. Smile | :)

It's not difficult but you have to formulate the question in a more accurate way, i.e. I think that the sequence you gave it's not correct (or I cannot guess correctly what do you want to do...)
I mean, you include

aa
ab
ac

but not

bb
bc

and

cc

that, I think, are legal sequences.
Moreover, do you consider

ba

and

ab

the same sequence or not?

Finally, I repeat, be more accurate in your request (or explain me what i cannot understand...)

Smile | :)

you are correct sorry it slipped my mind when i was giving the example

a
b
c
aa
ab
ac
ba
bb
bc
ca
cb
cc
aaa
aab
aac
aba

and so on

If it were numbers it would just be X=x+1 but in strings i cant figure it out.

in fact, more difficult (at least to me) then I expected. But finally (with a bit use of recursion):

public static void Main(string[] args)
{
  perms("abc");
  Console.Read();
}
public static void perms(string s)
{
  for (int iDigits=1; iDigits<=s.Length;iDigits++)
  {
    recurse(s, "", iDigits, 0);
  }
}
public static void  recurse(string sOrig, string sCur, int iDigits, int iLevel)
{
  iLevel++;
  for (int i=0; i<sOrig.Length;i++)
  {
    string sNew =sCur+sOrig[i];
    if (iLevel == iDigits)
    {
      Console.WriteLine(sNew);
    }
    else
    {
      recurse(sOrig,sNew, iDigits, iLevel);
    }					
  }
  iLevel--;
}

Hope that helps.

P.S. I made a try with perms("abcde") and it runs (the correctness check is up to you...) Smile | :)
