How to get list of programs

How do I get a list of programs running. I need to know if one program is running, WinDVD4. Does it have a special id or something. The best way would be if I could just get a list and get my prog to run through this list and to find WinDVD4 in it (shouldnt be hard)/

What code do I need or is there a bas file out there to do this.

Thanks ppl.

Oh and what I need then is to be able to change the length \ width of it to any pixels I want by typing those in.

Can I do all this through the mighty basic.

Thanks

You can use the FindWindow API to find the handle, or hWnd of the DVD program. You just need to know the class name, which you can find using a program called Spy++ that comes with Visual Studio. There is also a free program to do this on http://www.patorjk.com/ if you don't have VS. Next, you will need to find out to how to modify the metrics of a window, once you have the window handle, it won't take much to modify it using the appropriate API calls.

Copy/paste this into a module

VB Code:

Private Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare Function IsWindowVisible Lib "user32" (ByVal hwnd As Long) As Long
 
Private Const WM_GETTEXT = &HD
 
Private aCaptions() As String
Private lCount As Long
 
Public Function GetAllCaptions() As Variant
    lCount = 0
    Call EnumWindows(AddressOf EnumWindowsProc, 0&)
    If lCount Then ReDim Preserve aCaptions(lCount - 1)
    GetAllCaptions = IIf(lCount, aCaptions, Array())
End Function
 
Private Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As Long
    Dim sBuffer As String * 260
    If IsWindowVisible(hwnd) Then
        ReDim Preserve aCaptions(lCount)
        aCaptions(lCount) = Left(sBuffer, SendMessage(hwnd, WM_GETTEXT, 260, ByVal sBuffer))
        If Len(Trim(aCaptions(lCount))) Then lCount = lCount + 1
    End If
    EnumWindowsProc = hwnd
End Function

Copy/paste this to the declarations section of a form with a Listbox (List1) and a button (Command1)

VB Code:

Private Sub Command1_Click()
    Dim vCaps As Variant
    Dim lIndex As Long
    
    vCaps = GetAllCaptions()
    List1.Clear
    For lIndex = 0 To UBound(vCaps)
        List1.AddItem vCaps(lIndex)
    Next
End Sub

WOW

Thanks so much for that code

Gonna try it out

hope I will be able to change the window size.

OK

Got the list of programs working

But better yet that findwindow works great

OK so I have this now



hwnd = FindWindow("WinDVDClass", vbNullString)

I get hwnd as "1100" when WinDVD is running. Great

I did a search for changing the metrics but again it doesnt seem to be on the forums.

Anyone know how to do it.

I have to say a massive thank you to all who have helped me out.

Hope I can get this final thing now.

What kind of "metrics" are you trying to change?

I need to be able to change another programs width and length (window that is).

I have its info but what is the api code to do this

Anyone know about window length, height changing or what api code is needed.

KT

Private Declare Sub SetWindowPos Lib "User32" (ByVal hWnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long)

SetWindowPos me.hwnd, 0, 100,100,200,200,0 'makes the window at 100,100, with the w/h at 200/200

OMFG you guys are good, really good

Excellent man, not too buggy.....

One more thing my prog needs now.

Just one more and my prog is happy.

Will post later.....

Thankx man

Worked absolutely brilliantly

One more thing if you know it

Now I need to get the positon and width height of that program. I can set it now but now need to get what it is.

Thanks so much

I wonder is it possible to change the caption of the program I am changing res. Wouldnt mind putting my own little progs name in there.

Windvd tweaked by WinDVD Tweaker

Eh!!

Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long


Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type

Dim RCT as RECT

GetWindowRect me.hwnd, RCT

'then access it using RCT.left,right,top,bottom. width is right - left, height is bottom - top

Unbelievable!

Thanks man

lol

Private Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" ( _
ByVal hwnd As Long, _
ByVal lpString As String) As Long

hwnd = Window
lpString = New Caption

I have one problem

Those all worked great but now

i have a button to move the window one pixel say up. When I click it, my prog loses focus so I added in

form1.setfocus after the move.

When someone needs to press this button many times the display looks kind of crappy, switching from the prog to mine.

Is there a way to get my prog to be always on top of this program so this wont be a problem.

KT

use this flag in the last parameter of SetWindowPos

Const SWP_NOACTIVATE = &H10

OMG man you did it again

Made me go OMFG this guy is good.

Tanks a million.

Can anyone give me a way to read what sizes Windows is using for Window Border and Title Bar because of course I am trying to change the size of the inside window and not the outside one (+borders etcetc..)

thanks

KT

its a great exemple

works fine
