GetWindowText() help

Code:

---

PTSTR buffer;
int length;

...

length = GetWindowTextLength(hwndEdit);

GetWindowText(hwndEdit, buffer, length +1);

---

Shouldn't buffer now have the text from the edit box? It doesn't.

No, you have to allocate memory to hold the string, eg. 1

Code:

---

TCHAR buffer[256];
GetWindowText(hwnd,buffer,255);

---

which runs the risk of truncation if the text is longer. Or, eg. 2

Code:

---

TCHAR *buffer;
int length;
length=GetWindowTextLength(hwnd);
buffer=new TCHAR[length+1]; /*or use malloc in C */
GetWindowText(hwnd,buffer,length);
/*and when you're done, free up the memory*/
delete[] buffer; /*or use free if memory allocated with malloc */

---

It works :D

Thanks again to everyone that helped me with this, I couldn't have done it with you.
