VS 2010 Application Window Disappears Sometimes?
Jan 6, 2012
So i have made this program which im done with. All code has been written and it is working as it should. I do however have one bug that is pretty wierd.
Sometimes the main window just dissapears ! And i cant get it to show it self again.. Rebooting my computer does not help.. And then sometimes it just randomly shows it self again, but only between runs.
The only thing that i can come up with that could cause this, is the part of code i have that saves the position of the window to application settings and reloads them upon run. So that you can move the window around your screen (in this case dual monitors) and then close it, and the next time you start the application it shows where you closed it the last time. This must screw up somehow.

Excuse me for posting this, but I have searched both Google along with this forum before asking this question, maybe I'm not using the right keywords but I apologize if it's easy to find.I would like to know how one could close a third-party window (application) if a specified string was found in the window title.

I am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.

I'm having problems with my VS2005 .Net2.0 VB.Net Windows forms application.When I start the application and work with it for a while it somehow disappears from the taskbar.To get the Application button back on the taskbar I use Alt+Tab to switch to the application and voila,.. the taskbar button is back.In my code and form I can't seem to find anything strange.ShowInTaskbar is set to trueFormborderstule = SizableIt is an MDI application that is used for administrative purposes on sql databases.

I submitted the same question a few minutes ago, but so far that hasn't appeared in the thread - I wonder why/ - I used the HTML to rite the code I used. When I Click the F5 / Strat Debug on menu the DOS-Based form appears and disappears immediately. I am able to run a DOS-Based program in the computer, I checked this after the Sample Console Application failed to run. The Code I used is given within the Brackets(System.Console.WriteLine("Hello World")).

I am using a virtual keyboard I have created to write text to a textbox. Before I start typing the caret is showing the current typing position and will continue to do so if I use the physical keyboard. The problem I have is as soon as I enter a character using the virtual on-screen keyboard the caret disappears and will not come back until I use the mouse to click inside the textbox. The following is the code I use for entering an 'h'
Private Sub H_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles H.Click
If My.Computer.FileSystem.FileExists(Application.StartupPath & "Click.WAV") Then
My.Computer.Audio.Play(Application.StartupPath & "Click.WAV")
[Code].....

In the designer, the MainMenu I have created disappears as soon as I am done editing it. Before, it remained visible and worked as expected. But recently, the MainMenu not only disappears in the designer after editing, but it does not appear in the application.Adding a NEW MainMenu shows up as expected, however alot of work was put into the original MainMenu and its menu items.Is there any way to get MainMenu to act as it should?

If you have ever noticed in the Task Manager, when you right-click on the running task, you have many options which include 'Minimize' and 'Maximize'. Is there anyway to do achieve this in vb?

I'm using the following code
' Visual Basic
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
[CODE]..........
Its straight off the Microsoft site found here: [URL]
When I add the required components and click on the button, my app simply disappears, closes, goes right back into a stopped state. No errors, No Warnings, No issues. Nothing. Its as-if there is a stray "END" just before the IF statement. (But there isn't) Its stopping right at the IF statement. My app (THEIR CODE) just makes it disappear and "Stop". The code was working about an hour ago, but now nothing, and thats the only code on the project.

I have a VB.NET form that takes up the whole screen. On Windows XP, the taskbar is not displayed when moving the mouse to the bottom of the screen. I have auto-hide set, and the taskbar is not locked. I tried the same thing on a Vista computer and it works fine. What am I missing on Windows XP? I need the auto-hide feature to work for my app like it does for other Windows apps.
