Thread: C GUI Problems

Hello, i made a C Program that identify the n° of bytes of a determined resource.


Here is the code:


rc.rc(Resource file)

Code:

#include "rc.h"


DD DIALOGEX 6,5,167,49
CAPTION "Testando"
{
CONTROL "Digite alguma coisa:",label,"Static",0x50000000,50,3,66,20
CONTROL "",txt,"Edit",0x500100C0,4,14,160,13,0x00000200
CONTROL "Criar",btn,"Button",0x50010001,56,29,54,13
}
data RCDATA
{
"C:\\cs.exe"
}

rc.h(Header File)

Code:

#define DD 1
#define btn 2
#define data 3
#define txt 4
#define label 5

Main File

Code:

#include<windows.h>
#include "rc.h"






LRESULT CALLBACK WinProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShowCmd)
{
DialogBox(hInstance,MAKEINTRESOURCE(DD),NULL,(DLGPROC)WinProc);
}




LRESULT CALLBACK WinProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
{
switch(msg)
{
case WM_CLOSE:
     PostQuitMessage(0);
break;

case WM_COMMAND:
     if(wParam==btn)
     {
     HRSRC hRes = FindResource(0, MAKEINTRESOURCE(DD), RT_RCDATA);
     HGLOBAL hMem = LoadResource(0, hRes);
     void *pMem = LockResource(hMem);
     DWORD size = SizeofResource(0, hRes);
     SetDlgItemInt(hwnd,txt,size,false);


   
     }
     break;
}
return 0;
}

Well the problem is that the program not return the number of bytes, its return 0
Someone knows the problem?


Thanks
Bye

Hello Again


The line

Code:

Return 0;

is not the problem, if you change this line

Code:

SetDlgItemInt(hwnd,txt,size,false);

by this:

Code:

SetDlgItemInt(hwnd,txt,"2222",false);

So the program return the numer 2222
=/

The problem is on some of resources functions, the variable "size" are not working, and I dont know why



Bye
