I am on the tutorial on winprog.org, and I am on the article "creating controls at runtime", and my code gets errors. here is my code:
case WM_CREATE:
{
HFONT hfDefault;
HWND hEdit;
hEdit = CreateWindowEx(WS_EX_CLIENTEDGE, L"EDIT", L"", WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_MULTILINE | ES_AUTOVSCROLL, 0, 0, 100, hWnd, (HMENU)IDC_MAIN_EDIT, GetModuleHandle(NULL), NULL);
}
errors:
Review the parameters passed to the CreateWindowEx function. nf-winuser-createwindowexa
The code posted above has omitted a required parameter for the new window's height.
@Daniel Shepherd When I cut and paste the posted code into an app created by the Windows Desktop wizard and add a #define for IDC_MAIN_EDIT various intellisense errors are issued in addition to the one mentioned in your question. Didn't you also see these, including E0165?
So I changed CreateWindowEx to CreateWindowA, and I changed the LPCSTR values to ConstChar values. it still gets some errors.
here is my code:
hEdit = CreateWindowExA(WS_EX_CLIENTEDGE, "EDIT", "", WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_MULTILINE | ES_AUTOVSCROLL, 0, 0, 100, hWnd, (HMENU)IDC_MAIN_EDIT, GetModuleHandle(NULL), NULL);
Errors returned:
Did you read my answer and look at all of the error messages? It's still the same mistake.
I went to the link you shared and figured out I had missed the x and y properties. I added them, and my code worked! Thank you!
