Please HELP onchar() problem

Hai ,
I am using onchar() to catch what key is pressed , i need to set one variable if an alphabet is pressed .
In onchar() , the value we got is character code , we can do checking with VK_A ..... VK_Z .. so 27 checking is needed , is there any ohter way like VK_A has HEX value 41 ...VK_Z has 5A so what i did is if( nChar>41 && nChar< 5A) then setting my variable but it is giving error like 'bad suffic format'
i know i am comparing UINT and hex but i don't know how to correct this
please help me.
bye

Hi.

If you want to catch A~Z, try this format.

if((nChar >= 65) && (nChar <= 90))
{
Your job here.
}

If you want to use the Hex value... Just place 0x in front of the value:

if (nChar > 0x40 && nChar < 0x5B)

But why not just use:

if (nChar >= VK_A && nChar <= VK_Z)

Hi

(Please go to the top of the page and edit your profile, so we can have a name for you instead of Anonymous)

It all depends on where you're trying to get the keyboard input... What are you doing? Is this in a view, in a dialog with an edit control?

If you're trying to look for certain keystrokes in an edit control, then one would subclass the CEdit control (derive your own class from CEdit) and catch OnChar() there.

I have an example on my web site which shows how to derive a class from CEdit.

Go to http://home.earthlink.net/~railro/mfc_link.html and check out Example 5.
