Question

I have a CEdit and I want to extract the data using this.

wchar_t *temp = (wchar_t*)dialog.editbox.GetBuffer(0);
dialog.editbox.ReleaseBuffer();

Now i want to save this text in a object pointer like this:

selectedShape->setText(temp);

This work perfect, but only as long as you are in the scope of the method, because when I do a file save later, the text is not in the object anymore.

Does anybody know how I can save this wchar_t* for later?

The temp pointer is pointing to data that goes out of scope, so you’ll need to dynamically allocate memory to store the value. Something like this should work:

// Updated to use wstring, thanks praetorian
std::wstring tempStr((wchar_t*)dialog.editbox.GetBuffer(0));

Or:

int length = /*figure out the length here*/;
wchar_t *temp = new wchar_t[length];
memcpy(temp, dialog.editbox.GetBuffer(0), length*sizeof(wchar_t));
// dont forget to delete it like this: delete [] temp;
