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:

       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
                   [i](sumthang)[/i]
               End If
           End If
       Next

The window's 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

 

You'll need to declare GetWindowLong of course.

if i'm 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. :rolleyes:

 

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, i'm glad i found it.

 

thanks

Change the "Long" value types in the GetWindowLong declaration to "Integer". Long's 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.
