SendMessage problem

(1/1)

halsten:
I am using a Tab control in my project, that I recently wrote in MASM. However a part with the SendMessage API does not want to compile and generate the following output.


--- Code: ---error #2140: Type error in argument 4 to 'function'; found 'TCITEMA', expected 'long int'.
--- End code ---

Here's a snippet of what I have written so far.


--- Code: ---        [...]
        HWND hTab;

        TC_ITEM ItemStruct;

        HWND hDlgLog;
        [...]
        case WM_INITDIALOG:
hTab = GetDlgItem(hwndDlg, IDC_TAB);

ItemStruct.mask = TCIF_TEXT;
ItemStruct.pszText = "Log";
SendMessage(hTab, TCM_INSERTITEM, 0, ItemStruct);

--- End code ---

DMac:
Try this:


--- Code: ---SendMessage(hTab, TCM_INSERTITEM, 0, (LPARAM) &ItemStruct);

--- End code ---

Regards,
DMac
