Of course it will be 0. What is it exactly are you trying to do?

Thank you guys for your suggestions. I found the solution after searching a lot. Actually I wanted set of unique IDs to be assigned to a set of dynamically generated CEdit objects, so i was planning to convert from CString to UINT. If i use the following line where iEditId value is 1005(From resource.h)

unsigned int iEditId = IDC_EDIT5;

so next time i can simply increase the ID value by just increment the variable iEditId.

For(iIndex=0;iIndex<=5;iIndex++)
{
pEdit[iIndex]->Create(WS_CHILD | WS_VISIBLE | WS_DLGFRAME | ES_AUTOHSCROLL | WS_TABSTOP, CRect(110, (30 + iSize * 30), 260, (50 + iSize * 30)), this, iEditId + iIndex);
}

Solution 1

This code works fine and returns "12":

C++

CString abc = _T("12/12/2014");   
int date = _ttoi(abc.Left(2));

You surely don't want the integer value of "IDC_EDIT5" but the integer value of the content of the CEdit, don't you?

You are using the tag in the wrong way: IDC_EDIT5 is already defined in one of your header files, something like:

C++

#define IDC_EDIT5 1005

You just use that label as is to get its value, possibly to get an item like:

C++

item = GetDlgItem(hDlg, IDC_EDIT5);
