Change line 124 to:
SetWindowSubclass(this.mHandle, SUBCLASSPROC(&btnWndProc),
UINT_PTR(subClsID), cast(DWORD_PTR)cast(void*)this);
That is, change `&this` to `cast(void*)this`.
Hi,
Thanks for the reply. That will work like charm but we need to
change the code in subclassed button's WndProc like this--
extern(Windows)
private LRESULT btnWndProc(HWND hWnd, UINT message, WPARAM
wParam, LPARAM lParam, UINT_PTR scID, DWORD_PTR refData) {
try {
Button thisBtn = cast(Button)cast(void*)refData;
{
catch (Exception e) {}
....
