Problem With SetWindowsText

Hi,
I have code using one form for that. My code is pure win32.
I want try set one predefined text for one Edit_Box.

INT_PTR CALLBACK DialogFunc(HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
	HMENU hMenu;
	
	switch(uMsg)
	{
	case WM_INITDIALOG:
		
		break;
	case WM_COMMAND:
		switch(LOWORD(wParam))
		{
		case IDC_BUTTON2:
			char buff1[1024];
			char buff2[1024];
			char buff3[1024];
			hDlg1=GetDlgItem(hDlg,IDC_EDIT1);
			hDlg3=hDlg;
			read(pathh);
			MessageBox(0,UserSaved,0,0);
			SetWindowText(hDlg1,"reza");
			GetWindowText(hDlg1,username,1024);
			write(pathh);
			hDlg2=GetDlgItem(hDlg,IDC_EDIT2);
			GetWindowText(hDlg2,key,1024);
			if(memcmp(Get_Account_Number_FromWEB(),b1,sizeof(b1))==0 ){result=1; DestroyWindow(hDlg);}
			else MessageBox(0,TEXT("Wrong User or PWD"),0,0);
		  
			break;
			case IDC_BUTTON3:
				DestroyWindow(hDlg);
				break;
				case IDC_EDIT1:
		         break;
			case IDC_EDIT2:
              break;

			
		
		}
		break;
	case WM_CLOSE:
		SetWindowLongA(hDlg, GWL_WNDPROC, dwNewLong);
		DestroyWindow(hDlg);
		return TRUE;
		break;
	
	}
	return FALSE;
}

SetWindowText(hDlg1,"reza") not set "reza" in IDC_EDIT1.
I tried SetWindowTextA(hDlg1,"reza") too but not worked too.

How to solve that?
Regards,
