Greetings to everybody!

As subjected.I use vc++ to generate a very simple dialog resource,and then
compiled with rcc.exe accompanied with dmc:
rcc -32 mydialog.rc

it generated mydialog.res file.

In my main win32 SDK source file,I use DialogBox to try to load the dialog,but
it failed.

Doesn't  this make sense?Any solutions?
Thanks for your help in advance.

Regards,
Sam

Did you remember to include this .res file on the command line when 
linking your program?  Seeing what command lines you're using might help.

it failed.

By "failed", do you mean that the function returned an error value but 
otherwise did nothing?

Below is the resource file,I compiled it with 

rcc -32 testd.rc

it then generated 
testd.res.

testd.rc:

#include <windows.h>


101 DIALOG 129, 26, 180, 70
STYLE WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
CAPTION "Show Info"
FONT 8, "MS Sans Serif"
BEGIN
    EDITTEXT        102, 19, 15, 147, 12, ES_AUTOHSCROLL
    PUSHBUTTON      "&Quit", IDCANCEL, 107, 42, 40, 14
    PUSHBUTTON      "&OK", IDOK, 28, 43, 40, 14
END


Below is the D source file:
module testd;

//import std.c.windows.windows;
import win32.windows;
import std.string;
import std.conv;

import std.stdio;

import core.runtime;

int WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int
nCmdShow)
{
    
    try
    {
	
		Runtime.initialize;
		runModuleUnitTests;
	
		WNDCLASSEX wc;
		//memset(&wc,0,wc.sizeof);
		wc.cbSize=wc.sizeof;
		wc.lpfnWndProc=&DefDlgProc;
		wc.cbWndExtra=DLGWINDOWEXTRA;
		wc.hInstance=hInstance;
		wc.hCursor=LoadCursor(null,IDC_ARROW);

		wc.lpszClassName=toStringz("dialog");
		if(!RegisterClassEx(&wc))
		{
			MessageBox(null,toStringz("Register class

			return -1;
		}
	
	
		if(!CreateDialog/*DialogBox*/(hInstance, 
                     MAKEINTRESOURCE(101), 
                     null, cast(DLGPROC)&DialogFunc))
		{
			MessageBox(null,toStringz("Create Dialog

			return -1;
		}
		return 0;
    }

    catch (Object o)		// catch any uncaught exceptions
    {
		MessageBoxW(HWND.init, cast(wchar*)o.toString, "Fatal Error",
		    MB_OK | MB_ICONEXCLAMATION);
	
	
		return -1;		// failed
	
    }
    finally
    {
		
    }

	// run finalizers; terminate garbage collector
    Runtime.terminate;
    		
    return 0;
}



int  DialogFunc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
{
	switch(msg)
	{
		case WM_COMMAND:
		switch(LOWORD(wParam))
		{
			case IDOK:
			EndDialog(hwnd,1);
			return 1;
			case IDCANCEL:
			EndDialog(hwnd,0);
			return 1;
		}
		break;
		case WM_CLOSE:
			EndDialog(hwnd,0);
			return 1;
	}
	return 0;
}

I compiled with 
bud -O -release -gui -clean testd.d testd.res and it generated testd.exe.
When I run testd.exe,first I heard a beep,then windows popped up an error
messagebox:
testd.exe has encountered a problem and needs to close.We are sorry for the
inconvenience.

I tried to upload the screen shot but failed.

So where should I start from?

Sam

This should be extern(Windows). I'm surprised that compiled, it 
shouldn't have.

Yes.it compiled even without extern(Windows) ,maybe because I imported win32
package other than std.c.windows.windows.

After added extern(Windows) to it,all the same result. Oops!

No, it's because you put a cast in to suppress the error.

You are right.It is the switch statement.I followed your guide and finally make
it.Great!

Thank you so much!

Your problem is right here: In D, switch statements must have default 
clauses of there's any chance of the value being switched not matching 
any of the switches.  If there isn't, a SwitchError is thrown at 
runtime.  Presumably, the program crashes because there's nothing 
catching the error before Windows does.

The same applies in the inner switch.

Thank you so much for all your help! I make it finally.Now looking back found
it kind of easy,no much difference with VC++.:P
