Hello.

I have a cmd line process that returns a value via the command interpreter (using sytem()). How do I get the same result value using Createprocess()?

If I follow you correctly, you're creating a process and want to get it's exit code, right?

HANDLE hProcess = CreateProcess(...);
WaitForSingleObject(hProcess, INFINITE); // Make sure it's done
DWORD dwExitCode;
GetExitCodeProcess(hProcess, &dwExitCode);

If the process is still active, dwExitCode == STILL_ACTIVE.

Hope this helps.

How do I add a DLL to a project. I created the DLL so that is not a problem. I have exported the appropriate functions but I don't know how to add it to the project and load it etc. Thanks if you can help.

How to get the App(.EXE)'s full path in MFC application?

It's seem that the App's m_pszAppName and m_pszExeName member only contain the module name,is there a way to get the App's full path?

GetModuleFileName is one way to get it. GetFullPathName is another.

A Q&D way that has never failed (for me, at least) is to use value of "CWinApp::m_pszHelpFilePath", and just replace the extension with your app's extension (usually "EXE").

when I delete a certain object I get an assertation
_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

what is this and how do I fix it? Am I forgetting to do something in the destructor?

You have been writing to memory you haven't allocated.

   Several things may cause this:
      o You are trying to delete an invalid pointer (or a valid pointer to a stack-allocated object)
      o You are trying to delete something that has already been freed
      o You are trying to delete a pointer that was not allocated off of the same heap you are trying to deallocate it on
      o Something stepped over the beginning or end of the allocated memory, and trashed the heap's management information
      o Your heap may be corrupted

   Etc...  Good luck!  Hopefully, it is something simple like a double-delete.

   Peace!

Modal Dialog Box - Simple Question?

SeNs30-Mar-02 9:13

30-Mar-02 9:13

Ok this is quite a simple question, but..

In a modal dialog box message loop, how can
I make some code be executed as soon as
WM_INITDIALOG etc. has been processed and
the dialog is visible on screen?

Eg. I want something in the message loop like.......

case (dialog is now visible on screen):
{
blah;
blah;
}

I do not want to use any MFC.

Any thoughts/solutions welcome Smile | :)

You can do it in OnShowWindow(BOOL bShow) for example.
bShow will be true when the window is being activated or shown

OnShowWindow is MFC?

SeNs30-Mar-02 9:58

SeNs

30-Mar-02 9:58

Isn't OnShowWindow MFC?

I am writing a non-MFC app..

I have tried

case WM_SHOWWINDOW:
{
blah;
}

But the message is sent just before the dialog box is drawn... I need a message or something that is sent
just after the dialog has been drawn....

This is a common problem. Set a flag (bInitDlgDone) when your WM_INITDIALOG completes. In your WM_SHOWWINDOW handler, execute "blah" only if
bInitDlgDone is TRUE.

Ok I tried the flag thing, but the code "blah" is still
executed before the dialog is actually visible on screen.

Am I doing something wrong?

myflag is initially set to FALSE...

// inside message loop for dialog

case WM_INITDIALOG:
{
myflag=TRUE;
return TRUE;
}
break;

case WM_SHOWWINDOW:
{
if (myflag==TRUE)
{
blah;
}
}
break;

Hmmm. How about if you post a command from within your WM_INITDIALOG handler and execute "blah" in the command handler? What I mean is:

case WM_INITDIALOG:
  ...
  PostMessage (WM_COMMAND, ID_DO_BLAH);
  return (TRUE);

case WM_COMMAND:
  switch (wParam) {
    case ID_DO_BLAH:
      blah;
      break;
    ...
  }
  return (TRUE);

The idea as I see it, like this:

CString csTheString, csLookupWord;
if(csTheString.Find(csLookupWord, csTheString.GetLength()-csLookupWord.GetLength) >= 0){
  csTheString = csTheString.Left(csTheString.GetLength - csLookupWord.GetLength());
}

Maybe some mistakes, but you will see in debugger Smile | :)

Perhaps not the best solution, but...

CString string = "This is a string";
CString word = "string";

if (0 == string.Right(word.GetLength()).Compare(word) )
    string = string.Left(string.GetLength()-word.GetLength());
