View 3 RepliesLoad Event Can Not Get Fired At Runtime
Jul 27, 2011I have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.
Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.

View 1 RepliesC# - Asynchronously Fired Event Run Synchronously On A Form?
May 17, 2010[VS 2010 Beta with .Net Framework 3.5]I've written a C# component to asynchronously monitor a socket and raise events when data is received. I set the VB form to show message boxes when the event is raised. What I've noticed is that when the component raises the event synchronously, the message box blocks the component code and locks the form until the user closes the message. When it's raised asynchronously, it neither blocks the code, nor locks the form.
What I want is a way to raise an event in such a way that it does not block the code, but is called on the same thread as the form (so that it locks the form until the user selects an option.)

View 1 RepliesUpdate Event Isn't Fired In A Dynamic Gridview?
Feb 20, 2012I'm creating a dynamic gridview in vb.net using a connected sql database. Everything works fine except 1 thing: when i click the update command, the event just won't fire no matter what I do. the gridview goes into edit mode and the cancel button works fine. This has cost me over 2 days of googling but none of the solutions work. I used breakpoints to check if the code was executed, but it wasn't. If anybody has any experience in this:I believe the problem lies in the addhandler but it doesn't give any errors.I forgot to mention that the sql command was a test and sets the data in that field to 15, now it's 10, it works when i use a normal button or a static gridview.

The event does not exist, so I have to somehow create it.

View 5 RepliesInterface And Graphics :: Resize Event Not Fired When Form Loads?
Nov 4, 2009Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?
is there some other event that is fired when a form is shown, so I can call my resize code there?

That's all there is because I was just testing it out. imgPerson does exist, so that's not a problem.
