prohbit shift key in edit box............

If you do not want floating point numbers you can set the Numbers only property in resource editor. I hope it helps.

The below code will block the special charcters but permits alphabets and numbers

void EditEx::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if( !isdigit(nChar) && !isalpha( nChar ))
{
return;
}
CEdit::OnChar(nChar, nRepCnt, nFlags);
}

void EditEx::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) { if( !isdigit(nChar) && !isalpha( nChar )) { return; } CEdit::OnChar(nChar, nRepCnt, nFlags);} i hv used this method but its also restricting to enter float value while i want to enable float numbers as well plz tell me how to do it

:doh: Just modify the checking as follows if( !isdigit(nChar) && !isalpha( nChar ) && nChar != _T('.'))

if you want to use only numbers than you can use number property of EditBox.

BTW, if you only wanted to have an edit control into which you can enter a float value, there are hundreds of article about that subject, you only have to search for it on codeproject. Here[^] is an example. The problem with your approach is that it is not secure: nothing prevents the user to enter a dot several time. So, instead of reinventing the wheel and rewriting the validation code all over again(it's not that trivial because, you have also to take into account that the user might delete some characters, change the cursor location, ...) why don't you look for a control that does this already ?

if you want to block Special character than you can subclass your edit control and handle OnChar function like this.

void CMyEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
char szBuffer[100] = {0};
short int nCounter = 0;
short int iTemp = 0;
int iStartChar = 0;
int iEndChar = 0;

if(nChar != VK\_BACK && nChar != VK\_TAB )
{
	if(nChar != '.' (nChar < '0' || nChar > '9') 
		 && (nChar < 'a' || nChar > 'z')&&(nChar < 'A' || nChar > 'Z'))//here write those character you want to enter
	{
		return;
	}

		GetWindowText((LPTSTR)szBuffer, sizeof(szBuffer));
		
}

CEdit::OnChar(nChar, nRepCnt, nFlags);

}

Do you have an aversion against isalpha() and isdigit()?
