have you tried the FindWindow() API command? you can find a window using either the caption on the program, or it's classname, then it'll return a handle to that window, from there you can modify anything, if it returns null(or false) Then that caption, or classname is not running. <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href= </a><br>Experienced in , or have messed with : VC++, Borland C++ Builder, VJ++6(starting),VB-Dos, VB1 thru VB6, Delphi 3 pro, Borland C++ 3(DOS), Borland C++ 4.5, HTML,Visual InterDev 6, ASP(WebProgramming), QBasic(least i didnt start with COBOL)

Unfortunately, the application that I am looking for does not have a constant caption. The application I am trying to pin down is another VB utility that I have written for our 3-D modeling software. It is just a standard exe program. How would I find it using the classname? I have done this before using XLMAIN for Excel, but I am not sure how to go about it with this application.<br><br>Thanks

do you know the classname of the application? (almost all exe have a classname) <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href= </a><br>Experienced in , or have messed with : VC++, Borland C++ Builder, VJ++6(starting),VB-Dos, VB1 thru VB6, Delphi 3 pro, Borland C++ 3(DOS), Borland C++ 4.5, HTML,Visual InterDev 6, ASP(WebProgramming), QBasic(least i didnt start with COBOL)

far as classname goes, like IE when you use Spy++ (comes with Visual Studio) use Find window, and move the target over a unique part of the window, like with IE if I put it over this HTML view part the classname is Internet Explorer_Server, the classname of the frame is IEFrame., your program might have something similiar. <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href= </a><br>Experienced in , or have messed with : VC++, Borland C++ Builder, VJ++6(starting),VB-Dos, VB1 thru VB6, Delphi 3 pro, Borland C++ 3(DOS), Borland C++ 4.5, HTML,Visual InterDev 6, ASP(WebProgramming), QBasic(least i didnt start with COBOL)

That would be too easy. I do not have the complete Visual Studio package. When making a standard exe program, can you specify/define the classname? I can see the process in Task Manager. I have found code to list all of the running processes. It just seems a bit long for my needs. I will keep pecking around for something simpler like: IsThisDarnAppRunning("something.exe"

nope, the exe name cannot be specified, mainly because the filename has nothing to do with the application itself, you could have the same application with different filenames, still wouldnt make a difference. you might have it under /visual studio 6 tools , you may have spy++ , if not I can write you can application that shows you the classname of whatever your mouse is over. <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href= </a><br>Experienced in , or have messed with : VC++, Borland C++ Builder, VJ++6(starting),VB-Dos, VB1 thru VB6, Delphi 3 pro, Borland C++ 3(DOS), Borland C++ 4.5, HTML,Visual InterDev 6, ASP(WebProgramming), QBasic(least i didnt start with COBOL)

No, I do not have spy*.* on my machine. I do appreciate the offer to help me out, but I do not think that is required. The routine I found requires psapi.dll which I do not have either. I can just have the one app set up a flag which the other app can read. I was just trying to avoid messing with the other application. I guess it all pays the same! Thanks anyway!

I found a solution in vb-world.net. I was looking for FILENAME.exe and just checked: If TaskName Like "FILENAME". To list all running apps, create a new project, add a command button and a listbox, then insert this code. <br><br>Private Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, ByVal wCmd As Long) As Long<br>Private Declare Function GetParent Lib "user32" (ByVal hwnd As Long) As Long<br>Private Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long<br>Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long<br>Const GW_HWNDFIRST = 0<br>Const GW_HWNDNEXT = 2<br>Private Sub Command1_Click()<br> LoadTaskList<br>End Sub<br>Sub LoadTaskList()<br> Dim CurrWnd As Long<br> Dim Length As Long<br> Dim TaskName As String<br> Dim Parent As Long<br> List1.Clear<br> CurrWnd = GetWindow(Form1.hwnd, GW_HWNDFIRST)<br> While CurrWnd <> 0<br> Parent = GetParent(CurrWnd)<br> Length = GetWindowTextLength(CurrWnd)<br> TaskName = Space$(Length + 1)<br> Length = GetWindowText(CurrWnd, TaskName, Length + 1)<br> TaskName = Left$(TaskName, Len(TaskName) - 1)<br> If Length > 0 Then<br> If TaskName <> Me.Caption Then<br> List1.AddItem TaskName<br> End If<br> End If<br> CurrWnd = GetWindow(CurrWnd, GW_HWNDNEXT)<br> DoEvents<br> Wend<br>End Sub<br><br>Once again, thanks for your help!<br>

ah yes vb-world, been there before several times. <p>Karl<br><a href=mailto:kb244@kb244.8m.com>kb244@kb244.8m.com</a><br><a href= </a><br>Experienced in , or have messed with : VC++, Borland C++ Builder, VJ++6(starting),VB-Dos, VB1 thru VB6, Delphi 3 pro, Borland C++ 3(DOS), Borland C++ 4.5, HTML,Visual InterDev 6, ASP(WebProgramming), QBasic(least i didnt start with COBOL)
tclere - you should turn that answer into a FAQ <p>Mike<br><a href=mailto:michael.j.lacey@ntlworld.com>michael.j.lacey@ntlworld.com</a><br><a href= Cargill's Corporate Web Site</a><br>Please -- Don't send me email questions without posting them in Tek-Tips as well.

Add this one to your tool box.
