Load Event Can Not Get Fired At Runtime

Jul 27, 2011

I 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.

C# - 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.)

Update Event Isn't Fired In A Dynamic Gridview?

Feb 20, 2012

I'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.

Form Is Not Updating After Custom Class Event Is Fired

Sep 24, 2010

I'm having an issue where my main form isn't updating even though I see the event fire off. Let me explain the situation and share some of my code which I'm sure will be horrible since I'm an amateur. I created a class to take in the settings for running a process in the background. I add some custom events in that class so I could use that in my form instead of a timer.

Object Handle Events Fired In Other Objects Without A Special Sub?

Jul 28, 2010

I've been thinking about my options when it comes to events in vb.net.What I'd like to do is to track events that are fired in an application without explicitly declaring them with 'handles' sub. Here is a pseudo-[code]....

Yeah I know, not quite working, but is there any way of implementing something like this in vb.net? My end game is really to be able to monitor events fired in many objects from another object, isn't there a more maintainable way to do that then to add a special sub in each object that handles the event that I want to catch? I need some way to let one object handle events fired in other objects without a special sub, the AddHandler goes a long way, but I can't really use that dynamically like so:[code]....

Interface And Graphics :: Resize Event Not Fired When Form Loads?

Nov 4, 2009

Back 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?

I know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.

Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?

C# - Find Out If The "TextChanged" Event Is Fired If User Is Typing Into A Textbox Or MyTextBox.Text Is Called Programmatically?

Mar 9, 2012

Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.

Handle An Object's Object Property Changed Event In .NET Windows Forms?

Jun 7, 2012

I know how to handle a single objects property changed event very easily. I want to handle a objects property changed event that is part of another object.

Given Object:

[ObjectY = Y]
+ Public WithEvents X As ObjectX

I would like to do something like:

Private Sub XPropertyChanged() Handles Y.X.PropertyChanged

Right now I need to create a object that equals the object inside that object and then handle this variable pointers property changed, but that is just annoying.
