doubt in textbox controls used in MFC

[Paresh Chitte]

Use WM_KILLFOCUS for your text box and get the text using GetWindowText. I hope this is you want.

When click button use of

CEdit m_Edit;
CString str;
m_Edit.GetWindowText(str);
MessageBox(str);

And if you want to set a value dynamicly for editbox use of SetWindowText

Hai,, I cant really understand i brief my question.. Iam entering the values in edit box during runtime and displaying it... CEdit m_ce; m_ce.GetWindowText(); TCHAR szMsg[256]; wsprintf(szMsg,_T("hEIGHT: %ld "),m_ce); MessageBox(szMsg,NULL,MB_OK); error C2661: 'GetWindowTextA' : no overloaded function takes 0 parameters Thanks For Spending Your Precious Time Harshadha

int GetWindowText( LPTSTR lpszStringBuf, int nMaxCount ) const; void GetWindowText( CString& rString ) const; Use as below CEdit m_ce; CString str; m_ce.GetWindowText(str); TCHAR szMsg[256]; long lValue = _ttol((LPCTSTR)str); wsprintf(szMsg,_T("hEIGHT: %ld "),lValue); MessageBox(szMsg,NULL,MB_OK); -- modified at 6:26 Thursday 8th March, 2007

I wrote for you an exmaple and also GetWindowText needs to a parameter for hold values

Hai, Iam sorry for troubling you again but iam getting memory error like asking whether to retry or abort... If i click ignore its displaying msgbox with 0 in it.. Thanks Harshadha

[Paresh Chitte]

have you done validation on the text box like the input is only numeric value and not alphabet nor alphanumeric...

[harshadha]

NO

Hi, I think u havent created a member variable for the editbox. Simply you would have written like CEdit m_ce; It ll not work out. First you need to create a member variable for the edit box using class wizard with the control type as Edit. say, the member variable is m_editChar. then, CString str; m_editChar.GetWindowText(str); MessageBox(str); now, the str ll give u the value entered by the user in the edit box. Hope this ll solve your problem.

Thanks & Rgds, Sri..

So then why are not using CString with your MFC application?

Consider using AfxMessageBox().
