Hi,
I have created a CFormView based MFC SDI application. It has a CEdit control.

I wish to get the left and right position of the CEdit control and use those in GD+ shapes placement.

When I search I get solution for dialog based application, but not for CFormView based MFC SDI application

Please advise how to achieve this.

What I have tried:

I tried below code. It compiles but while running getting ucrtbased.pdb not loaded. When I comment out these lines this error goes away.

CRect programEditCntrlRect;
m_editCtrl.GetWindowRect(&programEditCntrlRect);
 // m_editCtrl is control variable for CEDit control.
this->ScreenToClient(&programEditCntrlRect);
int programEditCntrlX = programEditCntrlRect.left;
int programEditCntrlY = programEditCntrlRect.top;

You should use GetClientRect which will give you the actual dimensions of the client area of the Edit window. The left and top will both be zero, which you can then use as the starting point for your drawing.

Thanks,
Below code worked.

CRect programEditCntrlRect;
CWnd* prgEdit = GetDlgItem(IDC_EDIT_PrgTxt);
prgEdit->GetWindowRect(&programEditCntrlRect);
this->ScreenToClient(&programEditCntrlRect);

That is not an error. It just means it couldn't load a symbol file.

Use GetClientRect as I suggested as it will give you the exact dimensions without the need to call ScreenToClient
