res file problems im having

[william427]

this is in a res file the top one is for dialog and the second is for button.
my question is does the two numbers have to be 1000 and 1001 or is this any made up numbers?


thanks

Code: [Select]

#define IDD_DLG1 1000
#define IDC_BTN1 1001

Looks like WinAPI issue.

Those looks like made up numbers.

Wikibooks page under the title: "Windows Programming/Resource Script Reference".

Resource Identificator, ID: "IDs are allowed in range 0..65535 and preferred in range 1..32767.".

Code: [Select]

#define ID_MY_LEG 798
#define ID_MY_SOMETHING_ELSE 6664
#define ID_WHO_CARES_ABOUT_THIS_ID 11233

There are system resources too, like icons, cursors.

* Maybe it (- the range of resource id) depends on resource compiler that you are using.

Made up by the programmer, which is what I do.

Each dialog will start with a thousand base:
IDD_MAIN = 1000
IDD_ABOUT = 2000
IDD_OPTIONS = 3000
etc...

And controls on each dialog will go off that base number, i.e. controls on IDD_MAIN will be 1001, 1002, 1003, etc.  Controls on IDD_ABOUT will be 2001, 2002, 2003, etc.  This will allow about 999 controls on each dialog without clashing with another dialog.  Menus might start at 500 and go up.  Submenu items will go off that base number:  Main menu = 500, subitems will be 501, 502, 503, etc...  File menu might be 600 and subitems will be 601, 602, 603, etc...

You as the programmer, will make the rules on how you program.

What have you tried?  What research have you done?  Have you used the Windows API in another language?  If so, it is the same here.

You could use SetWindowTextA or SetWindowTextW for Unicode, which eventually just sends the message WM_SETTEXT; so instead of SetWindowText, you could just use SendMessage.

its not crashing,but it doesn't put teststring into the box.
is this the right way
thanks

Code: [Select]

                push dword TestString
push dword 0
push dword WM_SETTEXT
push dword 206
push dword [mywindowinstance]
call [SendDlgItemMessageA]
                ;;SendDlgItemMessageA, dword argv(.hwnd), dword 206, dword WM_SETTEXT, dword 0, dword dwText


[Gunner]

Have you read the documentation for SendDlgItemMessageA

Code: [Select]

LRESULT WINAPI SendDlgItemMessage(
  _In_  HWND hDlg,
  _In_  int nIDDlgItem,
  _In_  UINT Msg,
  _In_  WPARAM wParam,
  _In_  LPARAM lParam
);
For hDlg, your passing the hInstance of your app!  You need to pass the hWnd of your dialog! What does 206 mean for the nIDDlgItem parameter?  If you are trying to change the caption for the dialog, this should be IDD_DLG1
