[758] Problem with Editbox in win32 - posted: 2011-11-20 18:46:28
So what happens is that the application crashes if i write more than 11 chars in my "Editbox"

the code:

Code:
int32 length;
length = GetWindowTextLength(Edit1);
   if(length > 0) {
  length++;
  char* myText;
  myText = new length;
      
  if(myText != NULL) {
            
          int32 x;
    x = 0;
    x = GetWindowText(Edit1, @myText, length);

Code:
    x = GetWindowText(Edit1, myText, length);


using the @ symbol is to get a pointer...

since you have wrote

Code:
char* myText; //this is already a pointer
myText = new length; //allocates space.

//myText is already a pointer


example of when to use @

Code:
    char myText[1024];

    //code here
    x = GetWindowText(Edit1, @myText, length);
