Windows API... Status Bar problems.

**switchcase** · 10-11-2007

Hi. I'm trying to put a status bar in my win32 app, using the following code:
(in case of WM_CREATE Message)

Code:

HWND hStatus;
int statwidths[] = {100, -1};

hStatus = CreateWindowEx(0, STATUSCLASSNAME, NULL,
	WS_CHILD | WS_VISIBLE | SBARS_SIZEGRIP, 0, 0, 0, 0,
	hwnd, (HMENU)ID_STATUS, GetModuleHandle(NULL), NULL);

SendMessage(hStatus, SB_SETPARTS, sizeof(statwidths)/sizeof(int), (LPARAM)statwidths);
SendMessage(hStatus, SB_SETTEXT, 0, (LPARAM)"Test");

if(hStatus == NULL)
    MessageBox(hwnd, "Could not create StatusBar.", "Error", MB_OK | MB_ICONERROR);

I added the MessageBox bit in after I compiled and ran the app and saw no StatusBar. It seems hStatus is null and that no Status Bar has been created. Could somebody please advice me as to why this is? Thankyou for any replies.

Assuming that hStatus is a local variable, I would make it a static local variable.

Code:

static HWND hStatus;

How would this help at all?

Thanks for the reply.

The code you posted is correct except I would have checked hStatus right after I created the window. I incorrectly made the assumption that hStatus was somehow losing it's value, which is not the case after rereading your code. Since the code is correct, the only other issue that comes to mind is that you're possibly not calling InitCommonControls.

I apologize for the initial misinformation.

No need to apologise.

I've tryed using InitCommonControls() just before reading your recent reply, after reading through MSDN. Unfortunatly Im have problems getting this to work, as whenever I call InitCommonControls() I get a linking error. The error given by the compliler is:

Linking executable: F:\Dev\New\Win32GUI.exe
.objs\main.o:main.cpp

.text+0x600): undefined reference to `InitCommonControls@0'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 4 seconds)

Does this indicate any other errors i have made?

I have included commctrl.h, I really don't know what the problem is. Sorry if its obvious.

Thankyou.

Are you linking with comctl32.lib?
