I have a project with 2 forms. I need the code to be executed on one form first, which is why it is run first, then I want to hide it and just display the user interface form. I have the following code, it makes both forms appear, but I only want the user display form to show: [code] I call both these subs in the frmLoad of the Processing form.
View 3 RepliesThe documentation for an API I am using explicitly says that I need to call close() on an object when I am done with it. I would also like to log something there.I understand GC, might not happen at expected time, etc. etc. I still want to implement some code at cleanup.I read that I need to Override Finalize() to do this.I wrote a console app to test and it looks like it indeed works.However, this does not work with windows forms. I put a break point and it never gets hit in the Finalize method.How do you add some code to be executed at cleanup time for a window form?Here is my console app test:
Public Class Foo
Public Sub New()
Console.WriteLine("In Foo Constructor")[code]......
My problem is that some code I enter will not be executed. Here is an example of my Form Load event. If i debug the code then the first two lines are executed. The MsgBox won't be executed though. or anything else after it. My programm does run perfectly. But i cant make any changes anymore It's driving me nuts, I don't have the faintest Idea what could be wrong. I sent the code to a friend and he isn't having any problems at all. We both use win7 64bit (he has ultimate, i have home) [code]

I have a hashtable of a class that contains a timer. When this timer elapses x amount of time, it calls a subroutine within the class. This subroutine calls several other functions and subroutines and then its done until the timer elapses again. Now one of the subroutines updates a label on the form and i can see that happening when its supposed to. There is another subroutine that should be updating another label but it is not. I believe this would be a simple correction but when i set a debug point on the routine it does not work. I'm not going to post the code for this as it is hundreds of lines of code and its probably just a configuration in the IDE that got changed somehow.
I run break points around the rest of the project just fine, even in other classes that use timers. Does anyone else have this problem of code being executed but not being able to debug it?
I have a form that on load keeps closing without any errors... I have no clue what it wrong with it. How can I record all the lines of code being executed so that I can find out why it is closing. There are no errors or me.closes.

I have a backup script i made in VB. part of the code im having trouble with:
HTML
code:
Now this code is executed when a button is clicked, if the folder does exists, it displays a message and continues the backup. however if it does not it displays displays "does not exist box" then i want the application to close.
I played around with the application.exit commands but it seems like the code just skips over it, and continues to try and backup the data, then errors out. how do i make the application close, if the dir does not exist?
How do I wait until the report has finished rendering before the rest of the code gets executed?
View 5 RepliesI am developing a window application. I'm using Visual Studio 2005 and Mysql Database. The problem is, only one form is getting executed when I try to debug.I have changed the startup form to other forms(from a list of existing forms), but still that same old form is getting executed, even if I delete that form or exclude it from the project, it still keeps on executing.
Where this form is stored?(I deleted it from the folder where all other forms exist)

I want to add some action to my form when it is closed by clicking on the "X" button in the upper right corner of the form.How is this done? I suspect that i must add a handler for some event, but which event is it?
Currently i am using the closing event, but i dont get it to work properly.
I 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 have searched everywhere, and have not found an answer. I would like to know how to enable your form to detect if a process is started. Something like this:
If Process.Start("Process.exe") Then
MsgBox("Process is running")
Else
MsgBox("Process is not running")
End If

When I started to work on this new project in vb.net 2010, I put many breakpoints to try to understand the execution order of the project, only to find it in vain. Step into command F11 should work correctly according to Visual Studio 2010: Step Into Property/Function(F11) doesn't work as expected. But I when I pressed F11, I found the code is jumping from one place to another based on breakpoints, not line by line or step by step.To give an example, please see the code below
Me.tcData.Alignment = TabStrip.TabControl.TabAlignment.Bottom 'line 1-breakpoint
Me.tcData.Dock = System.Windows.Forms.DockStyle.Fill 'line 2
...
Me.tcData.TabsDirection = TabStrip.TabControl.FlowDirection.LeftToRight 'line 3
[code]....
When I press F11 at line 1, it goes to the property 1. After it returns, when I press F11,it goes to property 3 directly, without accessing the code in line 2 and line 3.I do not understand why the code is NOT executed step by step by using F11. If I put breakpoingts in line 2, then line 2 is executed.So it seems to me that the showed execution order is based on breakpoints! So if I put breakpoints at different places, the showed execution order would be different! Thus, it is impossible for me to really understand the execution order.

Assume I have an If-ElseIf decision to make. Do all ElseIf's get executed after one has been found true? [Code] Obviously that is not a real subroutine but I wrote that just to clarify what I'm asking. When this is run, on the second ElseIf the value is equal to 5 so whatever is inside that ElseIf would execute. Once that happens do the following ElseIf's get checked or does the program immediately go to the End If?
