Geting a proccess filename Kastellanos Nikos19-Jun-01 7:40 Kastellanos Nikos 19-Jun-01 7:40  I use spawncl(...) to run other applications. I then get the hWnd of the new application. (i use a hook to see when a wnd is created/activated/destroyed) The fuction ::GetWindowText(...) works fine and i get the windows title. But when i call ::GetWindowModuleFilename(...) i get the filename of my application, not the new one. If i run Task manager, i can see the filename of the new application! What can i do? Is there another way to get the filename instead of ::GetWindowModuleFilename(...) , or i souldn't use spawn(...) and use CreateProcess(...) or RunWin(...) ? - - - - - - - - - - - - - - - - - - Memory leaks is the price we pay \0 01234567890123456789012345678901234 Re: Geting a proccess filename Tomasz Sowinski19-Jun-01 8:48 Tomasz Sowinski 19-Jun-01 8:48  What exactly is the problem? You are passing the executable filename to the spawn/CreateProcess/WinExec. Why do you want to retrieve it using hwnd? Do you think Windows is replacing your exe with something else?

I didn't describe it correctly. My application sets a system hook to get notified for all created windows. That's why i want to get the filename from the hWnd. It's not limited to the programs that i run with spawn*(...). - - - - - - - - - - - - - - - - - - Memory leaks is the price we pay \0 01234567890123456789012345678901234 Re: Geting a proccess filename Kastellanos Nikos19-Jun-01 21:35 Kastellanos Nikos 19-Jun-01 21:35  How can i disagree.

Thanks in advance!! Rob Jones Re: Hiding a dialog box Tomasz Sowinski19-Jun-01 9:07 Tomasz Sowinski 19-Jun-01 9:07  Do you expect your dialog to be always invisible? Or only until some event occurs? Tomasz Sowinski -- http://www.shooltz.com.pl Re: Hiding a dialog box RobJones19-Jun-01 9:21 RobJones 19-Jun-01 9:21  always invisible. Rob Re: Hiding a dialog box Tomasz Sowinski19-Jun-01 9:50 Tomasz Sowinski 19-Jun-01 9:50  If your app targets NT/W2K only, you can consider creating a service. If you need to run on Win9x, hiding main window should work.

John Uhlenbrock19-Jun-01 6:35 John Uhlenbrock 19-Jun-01 6:35  I *finally* figured out how to use the CTime class successfully... CTime CurrentTime = CTime::GetCurrentTime(); or CTime CurrentTime; //blah blah CurrentTime = CTime::GetCurrentTime(); I don't get it. Why do you have to do it that way, and why doesn't the following work... CTime CurrentTime; CurrentTime.GetCurrentTime(); - John ------------------------------------------------ Before you critisize a man, walk a mile in his shoes. Then when you critisize him, you are a mile away and have his shoes. Re: CTime... Carlos Antollini19-Jun-01 6:43 Carlos Antollini 19-Jun-01 6:43  CTime tm = CTime::GetCurrentTime(); If you want to Know the Hour or the minutes, you can do: CTime tm = CTime::GetCurrentTime(); int nHour = tm.GetHour(); int nMin = tm.GetMinute(); etc. Regards... Carlos Antollini. Re: CTime... John Uhlenbrock19-Jun-01 6:45 John Uhlenbrock 19-Jun-01 6:45  I think my question was unclear. I don't understand why the CTime object has to be initialized that way. Why can't it be initialized like this: CTime tm; tm.GetCurrentTime(); - John Re: CTime... Carlos Antollini19-Jun-01 6:55 Carlos Antollini 19-Jun-01 6:55  Because the definition of GetCurrentTime is CTime GetCurrentTime(); And not void CTime::GetCurrentTime(); I think that this is a cuestion for the Microsoft Developers..... Is True, Is more is more intuitive of the other form, but they developed it of that way. Cheers!!!! Carlos Antollini. Re: CTime... Chris Meech19-Jun-01 7:15 Chris Meech 19-Jun-01 7:15  I'm not sure of the exact implementation details, but did you notice that the GetCurrentTime method of the CTime class is a 'static' method? That is the reason for how it is used. Why it's declaration is such, I don't know. That relates to how the developers decided to do things. Chris Re: CTime... Vikash Dubey19-Jun-01 10:55 Vikash Dubey 19-Jun-01 10:55  Yeah GetCurrentTime is a static method that is why you call it using that syntax. The method create a CTime object in this way CTime(::time(NULL)). The GetCurrentTime is creating a new CTime Object of which the member m_time contains the latest time.The assignment operator copies this value CTime tm; tm=CTime::GetCurrentTime();// operator=(const CTime& timeSrc) comes into action Mail back if you have more info Re: CTime...

Can I do similar things in VC++ 6? Thankyou Re: Graphs RobJones19-Jun-01 7:53 RobJones 19-Jun-01 7:53  Its easy to do... For example if you have just created a dialog type application you can right click on the dialog and pick Insert ActiveX Control, from here you can pick your ActiveX grid or excel controls.. or from the the menu bar in Visual C++ pick "Project" then "Add to Project" next chose components and controls.. then go to Registered ActiveX Controls folder. Have Fun!

Cuold someone help me? I would grateful if you would send me an example code. Thanks. Re: ATL Carlos Antollini19-Jun-01 6:29 Carlos Antollini 19-Jun-01 6:29  Do you want to say with "finish the connection"? Carlos Antollini. Re: ATL 19-Jun-01 7:01 19-Jun-01 7:01  I don´t know the instructions that I have to put in VB to get that the server in VC++ send message to VB, VB catch this msg and display it. Cuold you respond me now? Re: ATL Carlos Antollini19-Jun-01 7:05 Carlos Antollini 19-Jun-01 7:05  CreateObject() Carlos Antollini. Re: ATL Michael P Butler19-Jun-01 22:27 Michael P Butler 19-Jun-01 22:27  Look at the Implements keyword. Quick pseudo code example to give basic idea. Implements IConnection Dim obj as Object Dim Cookie as Long private sub Form_Load() set obj = CreateObject("myapp.object") Cookie = obj.Advise(Me) end sub private sub Form_Unload() obj.Unadvise(Cookie) end sub private sub IConnection_MyConnectionPoint MsgBox "Called by VC++" end sub
