There must be an easier way then what I'm doing to determine if the first
character in a string is a valid letter. My code is getting to big. There must be a better way. Thanks in advance
The only thing wrong with it is that I couldn't find it

While I was at it I should have asked you about trimming a string of leading
white space. Is there a easy way? I've been searching the doc and the internet but can't find anything.

I'm doing plain C
Can you see what is wrong with the while statement ComboBox_GetText(GetDlgItem( hDlg, IDC_N_USERNAME), szTmpStr, SIZE_OF_USER_NAME); strcpy_s(szTmpStr2,72,szTmpStr); strcat_s(szTmpStr2,72, "5"); //Make sure the strip code that follows leaves something while (iswspace(*szTmpStr2)) szTmpStr2++; //Error 1 error C2105: '++' needs l-value if( !isalpha(szTmpStr2[0])) //check the first character Thanks for the reply [quoted text, click to view] "David Wilkinson" <no-reply@effisols.com> wrote in message news:ewubFzVRHHA.4252@TK2MSFTNGP05.phx.gbl... > Frank wrote: > >> While I was at it I should have asked you about trimming a string of >> leading white space. >> >> Is there a easy way? >> >> I've been searching the doc and the internet but can't find anything. > > Frank: > > If you are using CString then there is TrimLeft(). > > David Wilkinson

I should have given you one more line of code
ComboBox_GetText(GetDlgItem( hDlg, IDC_N_USERNAME), szTmpStr, SIZE_OF_USER_NAME); strcpy_s(szTmpStr2,72,szTmpStr); strcat_s(szTmpStr2,72, "5"); //Make sure the strip code that follows leaves something while (isspace(*szTmpStr2)) szTmpStr2++; //Error 1 error C2105: '++' needs l-value if( !isalpha(szTmpStr2[0])) [quoted text, click to view] "Brian Muth" <bmuth@mvps.org> wrote in message news:ecgzY%23VRHHA.2212@TK2MSFTNGP02.phx.gbl... > > " Frank" <frank@a-znet.com> wrote in message > news:erSpe7VRHHA.996@TK2MSFTNGP02.phx.gbl... >> I'm doing plain C >> Can you see what is wrong with the while statement >> ComboBox_GetText(GetDlgItem( hDlg, IDC_N_USERNAME), szTmpStr, >> SIZE_OF_USER_NAME); >> >> strcpy_s(szTmpStr2,72,szTmpStr); >> >> strcat_s(szTmpStr2,72, "5"); //Make sure the strip code that follows >> leaves something >> >> while (iswspace(*szTmpStr2)) szTmpStr2++; //Error 1 error C2105: '++' >> needs l-value >> > > char *p = szTmpStr2; > while (iswspace(*p)) p++; > > >
