Window State

[hitechoutlaw]

is there a way to run through the processes every so often and check to see if a program has been minimized and if it is then maximize it? if so, how?

i was thinking along the lines of:
[VB]
Dim processes(), p As Process

processes = Process.GetProcesses()
For Each p In processes
If Not (p.MainModule Is Nothing) Then
If System.IO.Path.GetFileName(p.MainModule.FileName).ToLower() = "game.exe" Then
(sumthang)
End If
End If
Next
[/VB]

The windows style will have WS_MINIMIZE style applied to it if the window is minimized. Use the Win32 API function [api]GetWindowLong[/api] to determine if this style is present.

Const GWL_STYLE As Integer = (-16)
Const WS_MINIMIZE As Integer = &H20000000


Dim pStyle As IntPtr = GetWindowLong(p.MainWindowHandle, GWL_STYLE)


If (pStyle And WS_MINIMIZE) <> False Then
    Window is minimized
End If

Youll need to declare GetWindowLong of course.

if im not mastaken (which i might be) that will only work on the app its run in, i want it to check to see if an app is being run and if it is, then if it is minimized or not.

thats why i was looking through the processes for "game.exe"

what do u or anyone else think?

 

[Derek Stone]

I think that code works. Try it. *nudge*

 

[hitechoutlaw]

i get two error messages and have no clue where to take it from here

Name p is not declared
&
Operator And is not defined for types System.IntPtr and Integer.

 

[Derek Stone]

You declared "p" in your code... which is why I used it.

Change the IntPtr to an Integer, for sake of simplicity.

thanks for ur help

now if gives me an error:

Value of System.IntPtr cannot be converted into long.


i know some people on the internet would give up after the first answer, this form has the nicest people u can find on the net, im glad i found it.

thanks

Change the "Long" value types in the GetWindowLong declaration to "Integer". Longs in Visual Basic .NET are 64-bit, while in Visual Basic 6 they were 32-bit. This makes a huge difference when calling a Win32 API function.

my program brings up an exception that has never come up before:
---------------------------------------------
An unhandled exception of type System.ComponentModel.Win32Exception occurred in system.dll

Additional information: Access is denied
---------------------------------------------
at this line:

If Not (p.MainModule Is Nothing) Then

it has always worked before in other programs but now it wont work in any of my programs.
