var->GetWindowText(szVal);//szVal is a CString variable.

I still get the same error.what i have to do is ,when i click a button,I get another dialog with the edit box.when i enter the value i have to get in the mesagebox and also for further processing.
the error is left of '->GetWindowTextA' must point to class/struct/union

What is the type of var ? You probably have to use a "." instead of a "->".

var->GetWindowText(szVal);//szVal is a CString variable.AfxMessageBox(szVal);
This is wrong.

If 'var' is ur control variable, then you should call like this.
var.GetWindowText(szVal);

Can you show your code and your declares?

If you want to call GetWindowText() you should add the member variable as "Control" not as value. Also after adding member variable you should call as follows.

CEdit m_Edit;
CString csTemp;
m_Edit.GetWindowText(csTemp);

Another way is add memeber variable as "value" and select appropriate type from "Variable Type" combo box. Abd Call UpdateData() for getting the data entered in edit box.

Hi Can you please paste your code snippet.

Addcam c;<br />
	c.DoModal();<br />
        CEdit m_edit1;<br />
	CString csTemp;<br />
	m_edit1.GetWindowText(csTemp);<br />
	AfxMessageBox(csTemp);

where Addcam is the class of the dialog which is invoked when the button is clicked.

Your m_edit1 is not associated with any editbox.
if you have your edit box on dialog pointed bye variable c
then you need to have a string variable in calss AddCam say strTemp.
When you press OK on dialog store the string from edit box to strTemp using GetDlgItemText(IDC_EDIT1,strTemp).

then use the strTemp for further processing using c.strTemp.
I hope it makes sense.
one more thing you cant access the control variables after the dialog is destroyed.

Sandip.

Is the m_edit1 is in Addcam dialog?

yes...its the edit box in Addcam dialog.have three more edit boxes there.

SandipG 8-Jun-08 23:10

You cant access the control variables after the dialog is destroyed.
You need to store the values in strings and access them after the DoModal() call.

Addcam c;<br />
  c.DoModal();<br />
  CString st;<br />
  st=GetDlgItemText(IDC_EDIT1,c.strTemp);<br />
  AfxMessageBox(st);

have added strTemp in Addcam class.

Addcam::Addcam(CWnd* pParent /*=NULL*/)<br />
	: CDialog(Addcam::IDD, pParent)<br />
{<br />
	//{{AFX_DATA_INIT(Addcam)<br />
	//}}AFX_DATA_INIT<br />
		CString strTemp;<br />
	<br />
}

SandipG 8-Jun-08 23:38

CString strTemp;
should be class member of AddCam

projectip wrote:
st=GetDlgItemText(IDC_EDIT1,c.strTemp);

should be inside AddCam::OnOK()//

then just write
Addcam c;
c.DoModal();
AfxMessageBox(c.strTemp);

I hope its making sense to you..

Sandip.
