deselecting text..

[xs2ahmed]

Hi:
i am using following code
//CTextEditor is propertypage
//m_Editor is CEdit
BOOL CTextEditor::OnSetActive()
{

m_Editor.SetWindowText(m_Text);


return CPropertyPage::OnSetActive();
}

the result is that the whole text in the CEdit is selected...can someone help me how to stop selection of the text...
thanks
Ahmed

m_Edit.SetSel(0,0) to put the insertion mark before the text.
m_Edit.SetSel(-1,-1) to put the insertion mark after the text.

try it out.

CEdit *e;
e=(CEdit*)GetDlgItem(IDC_SEARCHTEXT);
e->SetSel(-1,m_SEARCHTEXT.GetLength(),FALSE);

//IDC_SEARCHTEXT => id of the edit control
//m_SEARCHTEXT => CString variable of IDC_SEARCHTEXT

Are you sure that this will work? It is not mentioned in the documentation and usually I did

m_Edit.SetSel(m_Content.GetLength(), m_Content.GetLength())

where 'm_Content' is an associated member variable of type 'CString' to the content of the edit control...

Yes, it works, although I must admit that it is not documented exactly like that. MSDN says:

If the nStart parameter is 0 and the nEnd parameter is –1, all the text in the edit control is selected. If nStart is –1, any current selection is removed. The caret is placed at the end of the selection indicated by the greater of the two values nEnd and nStart.

This always made me conclude that -1 generally means "after the last character", and in fact, it behaves like that. But I agree that using GetLength() is somewhat safer.

Well...that is the kind of fun I always have with the MSDN. The october 2001 version does not mention it the way as you have quoted for the edit control...

From your quote it is at least clearer than what I have...

setsel is not working...
Rather when i changed the tab order of CEdit ... now its working fine..It was the tab order creating problems..it was setting focus to CEdit when activating...
Thanks
