I have the problem in every project.
First I thought something in my large project I work on is wrong.
Then I was happy that I could boil the problem down to even simple projects like the "hello world" example I mentioned in detail. I tried other projects as well. The problem is always the same: a break point in the code of a click event results in a program crash when I click the questionable button.
Best wishes from Germany

About the only suggestion I have is to uninstall VS2005 and reinstall it.
|
|
|
|
|
will give it a try.
It's VS.net 2003 plus Update for VS.net 2005. It really takes a while, but I guess it's worth to be checked out.

Finally I've found the solution:
The firewall caused the problem. I posted the details in the following forum:
MSDN Forums > Visual Studio > Visual Studio Debugger > VB.net2005: Setting a breakpoint (in click event of a button) causes programm

Hello Friend,
I've faced the following problem related to timeout.When I am going to save something large value in sql server 2005, following message is displayed.
"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
Please tell me the solution.
Thanks!

Try increaing the connection timeout and query timeout on the connection. That should do the job. You should also see if you can improve the performance of your sql code.

I've written following connection string
gConnectionString = "Integrated Security=SSPI;trusted_connection=true" + ";database=" + database + ";server=" + server + ";Connection Timeout=1200;";
Is n't enough?

Are you closing your connections when you are done with them? If you don't close the connection they stay open until the garbage collector gets the connection object. If that happens it is very easy to run out of connections.
Also, why are you asking this in the VB.NET forum - there is a perfectly good C# forum when your question is about C#.

i have an email client application using native .Net smtp classe for sending the mails
can any1 help to be able to send these mails across a proxy server?
Thanks

The mail classes in the .NET Framework do not currently support accessing an SMTP server through a proxy. You'd have to use a third party library to do this for you or use a properly configured proxy server. The proxy would have to be configured to automatically send any connection attempt on port 25 to a configured SMTP server.

how to identify tab key press in vb.net
winnie
|
|
|
|
|
You can set the property AcceptTab of the control. Then you get the KeyDown, -Press, -Up - Events.
But to get the focus-change, you must then use the mouse.

I have an app where I have a parent and child form. How can I capture the key that is pressed (if any) on the child form? I tried the keydown method, but when I run the program, it will not enter the method when I type a key.
Any help would be appreciated. Thanks.

the 2 forms are completely independent of each other even though you started one from another. event or delegate is the proper way to go.
the event example(done by memory - syntax is mostly good)
public class form1
private withevents mForm2 as form2
private sub ChildKeyDown(sChar as string) handles mForm2.ChildKeyDown
msgbox("the key pressed was: " & sChar
end sub
'add logic to show form2
end class
public class form2
event ChildKeyDown(sChar as string)
private textbox1_keydown(sender , e ) handles textbox1.keydown
raiseevent childkeydown(e.keychar)
end sub
end class

hi
we are currently making a website, we also have a client in vb.net
the client works like gtalk where the user has to log in..
the same username and password will apply to the website and the client
is there anyway that we can post values/data from the client to the website, but it needs to be specific to the username provided by the user
in other word, what ever is uploaded from the client must go directly to the webpage of the specific user
any help would be most appreciated
thanks

I'd recommend developing a webservice to which your client app. 'talks'...

I'm using the SaveFileDialog in VB.NET 1.1 and would like to perform some processing if the user has clicked yes to overwritting an existing file but I cant seem to be able to catch this. I have tried to use something like (If SaveFileDialog.ShowDialog = DialogResult.Yes Then) but I cant seem to hit this condition at all. Any help please!

Have you tried using DialogResult.OK?
I hope this helps.
|
|
|
|
|
thanks but DialogResult.OK is only hit if the file does not exist and the over write dialog is not displayed. However when the overwrite dialog is displayed the buttons displayed are Yes/No and after accepting to overwrite I cant hit DialogResult.OK or DialogResult.Yes
