I'm looking for something like "End process tree" form task manager.
I start an application using ShellExecuteEx. I have its handle and TerminateProcess works just fine, however aplication starts its own processes which remain. Sending WM_QUIT message doesn't work at all. Question is how can I kill whole process tree?
I don't care about proper shutwown, so even "brute force" metods will do fine.
thanks for any help

After Some Line of Code
When I Call the Following Line in our Code
INmManager::CreateCall(INmCall**ppCall,NM_CALL_TYPE callType,NM_ADDR_TYPE uType, BSTR bstrAddr, INmConference

What do you mean by "hack the registry?" If you want to read from or write to the registry, why not use the intended functions?

Hi,
I'm trying to display the icons of some folders in a ListCtrl and it's all ok except the first icon. This one appears with a black shadow  and the rest are displayed correctly.
My code is this:
HIMAGELIST hList = ImageList_Create(32,32, ILC_COLOR32|ILC_MASK , 0, 100);
m_ImageList.Attach(hList);
m_ImageList.SetBkColor(ILD_TRANSPARENT);
for (i=0;i<num;i++)
{
SHGetFileInfo(path, FILE_ATTRIBUTE_NORMAL, &shfileinfo, sizeof(shfileinfo), SHGFI_DISPLAYNAME|SHGFI_ICON);
m_ImageList.Add(shfileinfo.hIcon);
m_listFile.SetImageList(&m_ImageList, LVSIL_NORMAL);
lvi.mask = LVIF_IMAGE | LVIF_TEXT;
lvi.iItem = i;
lvi.iSubItem = 0;
lvi.pszText = shfileinfo.szDisplayName;
lvi.iImage = i;
::DestroyIcon(shfileinfo.hIcon);
m_listFile.InsertItem(&lvi);
}
Does anybody know why occurs this? 
Thanks in advance!

Mr DAVID CROW
IS IT NECESSARY TO WRITE Extern"C" IN THE DEFINATION OF A FUNCTION(EXPORT FUNCTION) IN A DLL EXTENSION MFC.ACCORDING TO ME IT IS MEANINGLESS AS THESE DLLS CAN ONLY BE USED BY MFC APPLICATION.
TO MY PREVIOUS QUERY U SENT ME A MAIL.BUT I DELETED THAT MESSAGE.IF U DONT MIND CAN I GET UR EMAIL ADDRESS.PLS SENT THE ANS TO MY PREVIOUS QUERY.IT WAS,USING CREATEPROCESS() CAN I DO SILIENT SETUP OF .EXE FILE.I DOWNLOADED A WINZIP FILE USING URLOPEN()AND THEN RUN THE PROGRAM USING CREATE PROCESS().IT IS SHOWING ME THE SETUP OF WINZIP.I WANT TO HIDE THIS SETUP FROM USER.

EVEN IF I USE _declspec(dllexport) ,it is of no use to define the exxported function with extern"C".AS THERE NO INTERFACE PROBLEM DLL EXTENSION AND APPLICATION
but it is must in DLL Regular

Hi, I've not found any information on this anywhere, so any ideas you can give me will be helpful.
I'm using Visual Studio .net 2003, and I have a problem.
The problem is, whenever I try to view the contents of a struct that i've allocated whilst stepping through the code, every part of it appears to be undefined, yet, when the code accesses it, and prints various bits, it works fine. It just appears to be a problem of the debugger attaching to it.
The situation is this. I have one large struct that contains sub structs. I allocate sub structs on a per required basis, initializing the memory to zero after allocating it.
My Project uses C# as a front end, and c++ with .net extensions as a DLL. The DLL isn't really c++, but is C code compiled as C++ (using the project properties), so doesn't use any classes.
It is quite a large project, with the main file running to 5,000 lines, so I don't want to undertake a conversion to C++ .net without knowing that there is nothing I can do to avoid it.
To me, it appears to be a debugger problem. Are there settings that control this sort of thing?
Any ideas?
Thanks,
Dave Smith

You must initialize the struct, preferably by using new and a constructor instead of malloc. It's not a problem, It's just C++.

Hi,
when I use remove("c:\test.txt") the file is deleted, but can still be found in the recycle bin.
Is there a way to delete a file permanently ?? So that it is removed but not into the recycle bin ?
THx

I think you must have confused yourself, because remove simply calls DeleteFile, which does not move items into the Recycle Bin.
Perhaps you have a program running which intercepts file deletions?

Some applications, like the "Windows Picture and Fax Viewer" do not allow multiple instances to be launched. In this case, if I use CreateProcess or ShellExecuteEx to launch another instance, what happens is that the existing instance receives the document (in this case a .gif file), replacing the one that was being shown before.
The problem is that, if I use ShellExecuteEx, the process handle returned is already signaled and the WaitForSingleObject does not block until the viewer is closed. If I use CreateProcess, the same thing happens with both the process and the thread handles.
The MSDN says that ShellExecuteEx may return NULL in this case, but it doesn't.
My code is as follows:
CString sType = _T(".gif");
CString sFile = _T("c:\\temp\\logo1.gif");
TCHAR pszOut[1024];
DWORD pcchOut = 1023;
HRESULT ret = AssocQueryString(ASSOCF_INIT_DEFAULTTOSTAR |ASSOCF_REMAPRUNDLL,
ASSOCSTR_COMMAND,
sType,
"open",
pszOut,
&pcchOut);
CString sCmd;
sCmd.Format("%s",pszOut);
sCmd.Replace("%1",sFile);
// Launch the viewer
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );
if (CreateProcess( NULL,
sCmd.GetBuffer(),
NULL,
NULL,
FALSE,
0,
NULL,
".",
&si,
&pi ))
{
WaitForSingleObject( pi.hProcess, INFINITE );
}
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
The first time this code executes, the "Windows Picture and Fax Viewer" is launched and the gif is displayed properly. If I leave the viewer running and try to execute the code again, but with a different .gif file, the file is replaced in the viewer but the returned handles are signaled, which means that the WaitForSingleObject returns immediately.
I've noticed, that the process returned by CreateProcess and ShellExecuteEx is always signaled if a previous instance of the viewer is running, even if it was started in the command line by the user. Therefore, the possibility of this effect being caused by me not closing handles (which I do) or doing something wrong the first time I launch the viewer, for example is not true.
The command line to launch the "Windows Picture and Fax Viewer" is something like this:
rundll32.exe c:\windows\system32\shimgvw.dll,ImageView_Fullscreen C:\temp\logo.gif
Because it runs in a dll.
Any thoughts?

What's happening here is that the newly created process is detecting the existence of the existing process, sending it a message to update the display, then the new process simply exits. Because the process has exited, it is signalled. This is due to code in the program itself - there's nothing you can do about it.

Thanks, Mike.
This explains everything. But it also means that there is no safe way to wait for a process to terminate. Suppose an instance has been started manually by the user. Now, because your application does not know there is one instance of the viewer running, you try to launch one and wait for it to terminate. Just as you've described, it will return immediatelly and your application will think that the process has terminated... which is true, in some sense, but the viewer is still running with your file in it. In other words, if you are waiting for the application to terminate to free resources (deleting temporary files, for instance), you will do it prematurely.
How would you implement this?

I'm dynamically applying transparency to a bitmap I'm displaying (i.e., I'm making the background colour transparent using a mask).
The bitmap is user-sizable and I want to highlight it 'on mouse over'. So I managed to create a region from the mask and use it to FrameRgn. This works well when I leave it 'on' permanently. However, I only want the frame to display when I'm over the non-transparent areas on the picture.
Easy, I thought, I'll use PtInRegion. However, I can't seem to get it to work - my MouseMove code never thinks a point is in the bitmap region.
Can anyone with any experience give me any pointers?
Also, does anyone know how to 'undraw' a FrameRgn? Once it is drawn, it doesn't seem to wnt to go away...

well i dunno anthing abt PtInRegion.....but i can give u totally new way of doing it.....but u have to do it from scratch.....
derive a class from the CStatic and subclass it by embedding the WM_MOUSEMOVE and the WM_TIMER message on to it.....
then.....draw a static control then using the wizard,assign an object say m_obj(thru ddx and linked to the class that u have just derived)and using thiz load the image on to the ststic control by using the LoadImage() ..or anyother ....
in the OnMouseMove add the following code....
if(m_showframe==FALSE)//declare a bool variable and set it to Fiale in the constructor.....
{
ModifyStyle(SS_BITMAP,SS_GRAYFRAME);
m_showframe=TRUE;
m_update=TRUE;
}
in the Ontimer()...use the following code...
CPoint p(GetMessagePos());
ScreenToClient(&p);
// Get the bounds of the control (just the client area)
GetClientRect(rect);
// Check the mouse is inside the control
if (!rect.PtInRect(p))
{
KillTimer(m_nTimerID);
m_timeronce=0;
ModifyStyle(SS_GRAYFRAME,SS_BITMAP);
m_showframe=FALSE;
m_update=TRUE;//add in a timer in ur main dialog.....to keep checking for m_update if set the timer in the main dialog should redraw
}
hope thiz idea helpz u ......
cheerz.....

It is to ask that if somebody has any idea that how we can write a video codec and what are the basics for writing it and what should be the prior knowledge for this.

Here is a quick question for you. I have a program which I have embedded within a program. I am basicall trying to achieve a sort of security wrapper to the second embedded program. Anyway, I can write the embedded program to disc and execute it there, then delete it when done, but I would prefer to hold it im RAM. Is there any method by which a program can be held in RAM and executed?
Any thoughts and comments would be well received.
Many thanks

If the second program is embedded in the first as a resource, maybe something like this will help. (NOTE: I don't really know that this is even plausible, just a concept I came up with in my head).
Anyway, how about reading all the bytes of the 2nd executable into a byte array, find out where the address is for the wndproc or initinstance function, make a function pointer member in the first executable, then set the address of the function pointer to that address in the byte array (offset from the first byte, of course), and execute it. Does that make any sense?

Thanks for the post. I have been pondering along a similar line of thought myself. I'll give it a go later and see what occurs. Sounds like a plan though

Don't even waste your time thinking about this. The loader has a huge amount more to do than merely copying bytes into memory and then calling something.
Anyway, how would you know what to call? It's certainly not WndProc or InitInstance!
