View 1 RepliesIDE :: VB 2008 Express IDE Hangs On Form Redraw
Jul 8, 2009The VB2K8 Express IDE is hanging intermittantly when I click on the form's Design tab. The tab's work area goes blank and a wait cursor appears. I can't switch tabs or do anything else within the IDE at this point. I have to go to the Task Manager, end the VB taskk, and restart the IDE. VB is at SP 1 with .NET 3.5. I have no third party add-ins or controls except for the Visual Basic Power Packs which aren't being used. At this point it is annoying and I haven't lost anything yet but it is happening more frequently over time.

Jul 8, 2010I have detected a problem running my application under Vista 64 bits OS.
My application is developed using VB.NT 2008 and compiled as x86
I have a main form. In this form there is an option to open other form. TThis second form must return a few values to the main form. When the user click on this 2nd form, to return values, this form hangs up (2nd form hangs up)
But for what I could have known, it continues executing the rest of code that exists after to open form. I want to say that the form dialog (2nd form) is not closed (hangs up) but it the code continues being executed, because I have seen that inserts the data in the database.
The application not returns any error and any exception.

WinForms Form Hangs On Startup On One Machine
Jan 21, 2010For my VB.NET application, I'm using the windows installer that came with Visual Studio. I can successfully install and run my program on any computer in our office except for one. On this particular machine, my program will stall for about 30 seconds before being able to load the main form. When I start up the task manager, the CPU is hovering at about 0 to 1%, so its not really doing anything but freezing up. It will eventually load, but it really shouldnt take this long, especially when it loads instantly on other computers. Now this machine is windows xp with serverice pack 3 and .net 3.5 sp1.

INSERTING - Accepting Both The Forms Data And The TabControl Data
Jul 22, 2010I am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?

Formatting Data And Inserting Into Another SQL DB
Apr 8, 2009I am pulling data from one SQL Server database, formating the data and then inserting it into another SQL Server Database. I am looking for a faster way to do this than the one I am currently using. The data pull is about 37,000 rows, so formating it and inserting it one row at a time is very time consuming. I was hoping I could format it into a datatable and insert the datatable into second database essentially inserting all rows at the same time as if they wre within the same databse, but I have not found a way to do this.
Essentially the code (I have simplified it) that I am using...
