I migrate a project from vb6 to vb.net.In vb.net project form's events are fired randamly. I mean form_Activated event are fired first after that form_Load event are fire. and this events are fired more than one time.what condition form_Activated event fired before form_Load event.
View 2 RepliesI have a form that I call from another form. Whenever I call it using form.showdialog() or form.show() the form appears, but it never executes the code that is in the form_load sub.
What's the deal? I call other forms in the same manner and they all load and execute the load code without issue.
Create a Visual Basic project with a Form that displays a seating chart for a small theater. Assume that the theatre has 25 rows and each row has 10 seats. The following image shows the completed main Form for the solution.
Write statements in the Form Load event to instantiate an object from the splash screen form and then display it as a modal window. Write the statements so that when the main Form loads (after displaying the splash screen) it will dynamically create the 2-dimensional array of CheckBoxes on the Form. The CheckBoxes should be created inside a scrollable Panel control instance. Above the scrollable Panel control instance display the column numbers (1 to 10).
does anyone know why the form load event being completely ignored/bypassed during loading the app? The form loads but none of the code in form_Load sub being executed (yes I tried putting a break inside the sub and it didn't trap)
View 13 RepliesI have a problem concerning the Form_Loading event: When I want to load a new Form (ImageDisplay) the ImageDisplay_Load Event is not executed first.
Instead it runs through the global variables definitions and then executes a Private Sub called numericupdown1_changed.
The numericupdown1 field is part of the form I want to load and has not been touched.
That is my calling sequence:
Private Sub Dispalydata_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Dispalydata.Click
Dim myDisplay As New ImageDisplay

The strange thing is that for other forms in my code it works well and starts with the form_load function.
I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.
problem with no event fired after the wrapped ocx object with aximp sent out the message in a console application testing.
View 3 RepliesI 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 2 Replies[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 RepliesI'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.

View 4 RepliesI'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.

View 2 RepliesBack 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?

View 5 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

View 1 RepliesI 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?
