HEAP CORRUPTION DETECTED!
-
hallo, i have the following piece of code , when i try to delete the lpKeyPoint i get HEAP CORRUPTION DETECTED! LPPOINT lpKeyPoint; lpKeyPoint = (LPPOINT)new LPPOINT(); GetCaretPos((LPPOINT)lpKeyPoint); if(lpKeyPoint) { delete lpKeyPoint; lpKeyPoint = NULL; } How can i solve this problem? Thanks.

lpKeyPoint = (LPPOINT)new LPPOINT()
That should be:
lpKeyPoint = new POINT();

[My articles]thanks it worsk,but when i move the curosor up i get a worng value of y: CPoint* ptrKeyPoint = new CPoint(); int nCursorLine = 0; if((pMsg->message == WM_KEYDOWN)||(pMsg->message == WM_LBUTTONDOWN)) { if((pMsg->wParam == VK_RETURN) || (pMsg->wParam == VK_UP)||(pMsg->wParam == VK_DOWN) || (pMsg->message == WM_LBUTTONUP)) { GetCaretPos((LPPOINT)ptrKeyPoint); nCursorLine = ptrKeyPoint->y; } if(ptrKeyPoint) { delete ptrKeyPoint; ptrKeyPoint = NULL; } }

I think he can get that - what y value do you get ? 'g'

Ummmm - just don't use the heap, OK - this should work just as well:
CPoint keyPoint;
int nCursorLine = 0;
if((pMsg->message == WM_KEYDOWN)||(pMsg->message == WM_LBUTTONDOWN))
{
if((pMsg->wParam == VK_RETURN) || (pMsg->wParam == VK_UP)||(pMsg->wParam == VK_DOWN) || (pMsg->message == WM_LBUTTONUP))
{
GetCaretPos(&keyPoint);
nCursorLine = keyPoint.y;
}See what I've done there - I've declared and defined the CPoint item as a local, so it's on the stack. Then you don't need to worry about deallocation or anything. Much simpler.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

But corrupting the heap is much more fun. ;)
