Well I typed :-

That's 4 separate sentences all in one single HTML line.

This reminds me of the (according to Guiness' Records Book) shortest mail correspondence ever, which took place between some novelist whose name I don't care to remember and his editor. The former, after submitting his novel to the press, went to the country for a small vacation, and some days later he was curious as to how the novel was selling. He wrote this letter to the editor:
? and the answer was

Initialize your pointers to NULL and reset them again to NULL after deleteing them. This way you'll always know when they are pointing to allocated memory.

ehm.. like this:
delete m_pMyCtl;
m_pMyCtl = NULL;
m_pMyCtl = NULL;
dah... Is it right?

Sort of, tha last m_pMyCtl = NULL is redundant (or the first one, if you prefer )

Well, I tried checkd if my pointer was NOT NULL. and then delete myptr and then myptr = NULL but the compiler said something with memory problems... bla bla... damn I can't remember the debug error...

You probably forgot to initialize myptr to NULL in the first place. Read Nish's answer below for a better explanation about the scheme to follow.

This is what Joaquín meant :-
pVar=NULL;
...
...
...
pVar = new blah blah;
...
...
...
delete pVar;
pVar=NULL;
Now from whereever in your code you can do a :-
if(pVar) to know if it is allocated or deleted.

This does is not true when using MFC. In MFC use exceptions to detect out of memory situations:
int *ptr1 = 0;
try
{
ptr1 = new int[10];
}
catch (CMemoryException *ex)
{
delete [] ptr1;
}

Nor is it true with VC7 (that is unless you force it to use the VC6 new.)

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

I have to keep a few extra bytes in a data file when it is being created. But when the file is finished, these bytes have to be thrown away. I cannot have another copy of the file since it may be huge, and I have to put those bytes in the file for it may be moved away or deleted. That means I have to shorten the file.
I'd be very thankful for any good idea about truncating a file.

I have a hook dLL that I'd like to send a message back to the calling app.
Something like......
keyboard hook detects that F2 is pressed
dLL sends message to app
app shows dialog
main code in dLL as follows
///////////////////////////////////////////////////////////
#define WM_APPSTARTED WM_USER + 100
#pragma data_seg(".shared")
HWND g_mainWnd = NULL; //the server window handle
HHOOK g_hShellHook = NULL;
HHOOK g_hKeyboard = NULL;
#pragma data_seg()
#pragma comment(linker, "section:.shared,rws")
SYSDLL_API BOOL _Startup(HWND hwnd)
{
g_hKeyboard = NULL;
g_mainWnd = hwnd; // g_mainWnd is the main window handle
g_hKeyboard = SetWindowsHookEx(WH_KEYBOARD, MyProc, g_hInstance, 0);
if(g_hKeyboard == NULL)
MessageBox(HWND_DESKTOP, "hook fail", "BLAH", MB_OK);
if(g_mainWnd != NULL)
return FALSE; // already hooked!
g_hShellHook = SetWindowsHookEx(WH_SHELL, MyShellProc,g_hInstance, 0);
if(g_hShellHook != NULL)
{
g_mainWnd = hwnd;
return TRUE;
}
return FALSE;
}
SYSDLL_API LRESULT CALLBACK MyShellProc(int ncode, WPARAM wparam, LPARAM lparam)
{
if(ncode < 0 )
return CallNextHookEx(g_hShellHook, ncode, wparam, lparam);
if(ncode == HSHELL_WINDOWCREATED)
{
HWND hfoundApp;
hfoundApp = FindWindow(NULL, TEXT("my_window" ) );
if(hfoundApp)
{
PostMessage(hfoundApp, WM_APPSTARTED, lparam, wparam);
}
}
this is where I'd like the dLL to send a message to the callin app
but the message never gets to the app
thanks for your time
