CEdit subclass question
-
I created a new class that derived from CEdit. Here is OnChar function:
void CMyEdit::OnChar( UINT nChar, UINT nRepCnt, UINT nFlags) { if( nChar>='a' && nChar<='z') { nChar -= 'a'-'A'; } CEdit::OnChar(nChar, nRepCnt, nFlags); }I just wanted to capitalize all typed chars in the edit box. But It seem not to work. Where is the problem? Please, help. Thanks for reading. -

Second I am not even going to calculate what value this will result in. If you where going to convert ascii characters in this manner you would have to do the following:
if( 'a' <= nChar && nChar <= 'z' )
nChar = 'A' + (nChar - 'a');To do it properly you would do the following:
nChar = toupper(nChar);
Ok! I lied I (calculated) tried your equation and it worked (mathmaticaly), but don't do it. INTP

ES_UPPERCASEstyle? To change the style after the control has been created, useSetWindowLong(). /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com
