That doesn't really give you even numbers if i happens to be an odd number. If you want to do a better job, look at using the modulus operator.

Divide the user input by 2 and check for remainder. If there is an remainder means it is an odd number, vice versa. Smile | :)

Use the modulus operator % to get the remainder
For instance: if (number % 2 == 0) then its even, and if (number % 2 != 0) then its odd.

Code to print only EVEN numbers..

#include <iostream>
using namespace std;

int main()
{
    int num;
    cout <<"Printing only EVEN numbers..\n\n ";
	for(num = 1; num < 210;num++)
	{
		if ( num % 2 == 0 ) // using the modulus operator % to get the remainder 
		{
			cout << num << " is even\t ";
		}
	}
    cout <<"\n ";
    return 0;
}

Or you could use the simple expression

C++

int odd = num & 1;

I know, i'm a long term fan of the MSDN, the trouble usually is finding a good ref. and, once you found it to make sure you can find it again after a year or so. I recently lost a lot of usefull resources on a very nasty crash. Not happy Cry | :((

WS_TABSTOP

This is my first form in c++ win32, and I want to get the tab key rolling for testing my program code, so when I fill in the edit boxes, I can just tab to the text box.

I put this form in a mdi child window, and all the samples I found use a dialog box. GetDialogItem was quite popular.

With the create window, I added the WS_TABSTOP.

If I can figure out the message generated by having focus in the textbox, and pressing the tab key, I think I can get the message in the wndProc, and set the focus to the next textbox.

txt_Manage_CreateAccount_LastName_Field = CreateWindow(TEXT("edit"),
TEXT(""),
WS_TABSTOP | WS_CHILD | WS_VISIBLE | WS_BORDER | SS_LEFT,
winWidth - 205,
92,
180, 20,
hManage_CreateAccount,
(HMENU) IDC_MANAGE_CREATEACCOUNT_LASTNAME,
GetModuleHandle(NULL),
NULL
);
		SendMessage(txt_Manage_CreateAccount_LastName_Field, WM_SETFONT, (WPARAM)hFont_txt, FALSE);
ShowWindow(txt_Manage_CreateAccount_LastName_Field, SW_SHOW);

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
