Hi all,
I am trying to create a win32 based gui in dlang. So far so
good. I can create and display my window on screen. But for
handling messages, i planned to write something like message
crackers in c++. But since, my WndProc function is a
"nothrow" function, i cannot use any function without
"nothorw" in that WndProc. How to solve this problem ?
Hi,
You need to catch any exceptions inside of your WndProc so
they don't propagate:
LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM
wParam, LPARAM lParam) nothrow
{
try
{
// your code logic here may call throwing functions
}
catch (Exception e)
{
// You should log exceptions here
}
}
Hi, Thanks a lot. Let me try.
It worked. Thanks :) I have one more question. Which is better,
to include all the switch cases inside a single try catch or
write separate try catch for each switch cases ?
