Re: form view borders 30-Apr-01 22:30 30-Apr-01 22:30  Hi Nick - tweak the CREATESTRUCT in the view's overloaded PreCreateWindow... BOOL CMyFormView::PreCreateWindow(CREATESTRUCT& cs) { cs.style = WS_CHILD | WS_VISIBLE; return CView::PreCreateWindow(cs); } A Question on CTreeCtrl Jayanand30-Apr-01 19:51 Jayanand 30-Apr-01 19:51  Hi I am beginner in VC++. I have got a CTreeCtrl in my application from which I want to delete HTREEITEMs upon press of delete key. First I proceed to delete the related data structure for the HTREEITEM selected. Then I proceed to delete the HTREEITEM using the DeleteItem(HTREEITEM) method. If the HTREEITEM to be deleted is a folder with numerous sub items with in it, do i need to delete all sub items individually before deleting the parent HTREEITEM ? OR could i directly delete the parent HTREEITEM ? Please help me out on this. Thank You, Jayanand. Re: A Question on CTreeCtrl Nick Blumhardt30-Apr-01 20:32 Nick Blumhardt 30-Apr-01 20:32  Hi You can handle the TCN_DELETEITEM message that the tree control will send whenever an item is deleted ... this will happen for each child item after you delete a parent item manually. sorry this answer is a bit brief. Nick Re: A Question on CTreeCtrl Nick Blumhardt30-Apr-01 20:33 Nick Blumhardt 30-Apr-01 20:33  Hi You can handle the TCN_DELETEITEM message that the tree control will send whenever an item is deleted ... this will happen for each child item after you delete a parent item manually. You can delete the data for a child item when this message is sent. sorry this answer is a bit brief.

Any suggestions. Thanks. Re: DWORD to BSTR Igor Sukhov30-Apr-01 23:15 Igor Sukhov 30-Apr-01 23:15  Hi ! May be it's the one you'was looking for? #include <sstream> using namespace std; sstringstream ss; ss << LPCSTR(szSessionID) << LPCSTR(szSep) << LPCSTR(szIPAddress)\ LPCSTR(szSep) << ULONG(::GetTickCount()); CComBSTR szString(ss.str().c_str()); Best regards, ----------- Igor Soukhov (Brainbench/Tekmetrics ID:50759) igor_soukhov@mailru.com | ICQ:57404554 | http://siv.da.ru Context Sensitive Help kk930-Apr-01 10:46 kk9 30-Apr-01 10:46  Hi I would like to add a context-sensitive help menu into my current MDI project.

Thank you kk9 explorer IDockingWindow with edit control pro30-Apr-01 9:42 pro 30-Apr-01 9:42  hi, i want to use an edit control in a idockingwindow in the right pane of the explorer. the problem: if i press backspace to del the last letter in the edit control, the explorer goes one level up in the directory. so, how is it possible, to use the backspace (and all the other special keys) for the edit? thanks Re: explorer IDockingWindow with edit control Erik Thompson30-Apr-01 11:17 Erik Thompson 30-Apr-01 11:17  You need to implement IInputObject and the appropriate methods to get the backspace to work correctly when your docking window has focus. I am in the process of a couple articles that explain this and other things within Explorer bands and toolbars. If time permits hopefully this week 1 or 2 of the articles will come out. Cheers, -Erik ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My thoughts are my own and reflect on no other.

I'm trying to learn it by myself. How can I change the caption of a button? How can I disable it? I looked into the CButton Class and I can't find how to change it Anyone can answer this newbie question? (I wish this was as easy as VB) hehe Thanks Re: Changing CButton Caption? J Patel30-Apr-01 7:25 J Patel 30-Apr-01 7:25  CButton is derived from CWnd, so you can call methods like SetWindowText to change the caption or EnableWindow() to enable/disable the window. Look at all the methods of CWnd which will show you what you can do. HTH Jignesh Re: Changing CButton Caption? 30-Apr-01 7:40 30-Apr-01 7:40  Thanks a lot. I must admit that I should have looked at it hehe Re: Changing CButton Caption? F.Dost30-Apr-01 7:41 F.Dost 30-Apr-01 7:41  Try this: GetDlgItem(IDC_YOUR_BUTTON_ID)->EnableWindow(FALSE); GetDlgItem(IDC_YOUR_BUTTON_ID)->SetWindowText("new text"); F.Dost Re: Changing CButton Caption? 6-Jun-01 8:48 6-Jun-01 8:48  What i do is that in the dialog editor you put the & sign before the letter with the caption. I hope this is what you need . SAntiago Suarez Scrolling MDI Child F.Dost30-Apr-01 5:15 F.Dost 30-Apr-01 5:15  How can i make my child window scorll when contents are bigger than window size?
