First, I've never worked with resource files before.
My case is this: I took winsamp.d from the samples dir, and added these lines taken from Y Tomino's win32lib:

Code:
alias uint ULONG_PTR;
LPSTR MAKEINTRESOURCEA(WORD i){ return cast(LPSTR)(cast(ULONG_PTR)(cast(WORD)(i))); }
LPWSTR MAKEINTRESOURCEW(WORD i){ return cast(LPWSTR)(cast(ULONG_PTR)(cast(WORD)(i))); }
alias MAKEINTRESOURCEW MAKEINTRESOURCE;
extern(Windows) HICON LoadIconA(
  HINSTANCE hInstance,
  LPCSTR lpIconName);
extern(Windows) export HICON LoadIconW(
  HINSTANCE hInstance,
  LPCWSTR lpIconName);
alias LoadIconW LoadIcon;


I also changed this line in function doIt():

Code:
wc.hIcon = LoadIcon(null,MAKEINTRESOURCE(101));


Then I created a sample resource file, only containing this:

Code:
101                     ICON    DISCARDABLE     "d.ico"


Where d.ico is some icon someone posted once. I compiled the resource file, using DM's rcc, like this:

Code:
rcc winsamp.rc -owinsamp.res -32


Then I compiled everything together like this:

Code:
dmd winsamp.d gdi32.lib winsamp.res -L/exet:nt/su:windows:4


Great! Now I know how to put icons in my exes! Also, the window now doesn't have that ugly default app icon, but instead it has the alert icon instead of the icon I told it!! (the alert icon is the yellow triangle with the exclamation mark, just in case).

I'm sure you've all guessed what's next... what am I doing wrong?

When using one of the Load* functions to bring in an app-specific resource, you need to pass in the app's instance handle as the first argument. Passing NULL tells Windows to use a system icon (and in this case you are getting the warning icon). So try something like:

LoadIcon(GetModuleHandle(null), MAKEINTRESOURCE(101));

Alternatively, use the instance handle passed to WinMain.
