Stubborn ListBox

[LyMc]

I've been having the darndest time trying to get a ListBox to fill with data for me. The code looks like this:

static void BuildSchemeMenu()
{
	InitCommonControls();         // just to make sure this is not a problem.
	SendMessage (schemeControl, LB_RESETCONTENT, 0, 0);
	for (int i = 0; i < schemes->pointer; i++) {
		int j = (int) SendMessage (schemeControl, LB_ADDSTRING, 0, (LPARAM) (schemes->GetScheme (i)->name));
		XBox (MB_OK, "returned value %d, string is '%s'", j, schemes->GetScheme (i)->name);
	}
	int j = (int) SendMessage (schemeControl, LB_GETCOUNT, 0, 0);

The message box call assures me that the strings are being fed as I want them to be, and the return value from the ADDSTRING is always 0. Further, the j variable is also always 0, regardless of the number of strings in schemes->pointer. It's got to be something simple; I've messed with all the hard parts. It started out as a ComboBox with the same results; I switched to a ListBox so I could better see what was happening.

Are you sure schemes->pointer > 0?

Yup, checked it from 0 to 4,

Give up? It turns out the window handle, hDlg, was incorrect. I was incorrectly assigning the argument in the callback to the global, and the global was therefore wrong.

Yup, something really simple....
