Re: Problems with IMessageFilter in SDI Fredrik Skog21-Feb-02 0:33 Fredrik Skog 21-Feb-02 0:33  Funny, it works in the SDI app if I call AfxOleInit() first. In the dialog app there is no need for that. Cheers, /Fredrik Sonork ID: 100.11430:PhatBoy Beginner Dialog::OnOK() Question CreekDawg19-Feb-02 4:28 CreekDawg 19-Feb-02 4:28  Hi, I have a dialog based application with the standard "Ok" and "Cancel" buttons at the bottom. After the dialog app loads, if I press the 'enter' key, the app closes (the Dialog::OnOK() Event Fires). How can I override this action? In other words, I want to be able to press the 'enter' key and not close the application (not fire the OnOK() event method). How do I do this? Thanks. Re: Beginner Dialog::OnOK() Question v_krishnan19-Feb-02 4:34 v_krishnan 19-Feb-02 4:34  There are two ways to do this - 1. You can do this by overriding the OnOK function in your dialog class and do NOT call the base class OnOK in that function. 2. In the dialog editor remove the default button property of the OK button. Hope this helps Krishnan Re: Beginner Dialog::OnOK() Question Joaquín M López Muñoz19-Feb-02 4:35 Joaquín M López Muñoz 19-Feb-02 4:35  Please see Mike Dunn's C++ FAQ, §7.4. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Beginner Dialog::OnOK() Question Roger Allen19-Feb-02 4:37 Roger Allen 19-Feb-02 4:37  Put in your own OnOK(0 for the dialog, and have code liek this: CMyDialog::OnOK() { if (GetFocus() != GetDlgItem(IDOK)) return ; // only allow exit if OK has the focus } Roger Allen Sonork 100.10016 If I'm not breathing, I'm either dead or holding my breath.

Making a CRichEditView Readonly v_krishnan19-Feb-02 4:10 v_krishnan 19-Feb-02 4:10  Hi, How can I make the edit control of a CRichEditView read-only? Setting ES_READONLY flag does the job but messes up at other places.

Wish You Were Here-Pink Floyd-1975 Jet OLE DB 4 and PROPVARIANT peterchen19-Feb-02 4:06 peterchen 19-Feb-02 4:06  I found that the OLE DB provider for jet (aka access databases) does not correctly bind string columns to PropVariants. Upon return, the type is set "VT_BSTR", but the string is empty (but allocated). Findings: Jet 3.51: binds correctly to DBTYPE_BSTR, _VARIANT, _PROPVARIANT Jet 4 SP3: binds correctly to DBTYPE_VARIANT, but not to DBTYPE_BSTR or DBTYPE_PROPVARIANT. Anybody has an idea of an workaround? Peter Re: Jet OLE DB 4 and PROPVARIANT Steen Krogsgaard19-Feb-02 23:41 Steen Krogsgaard 19-Feb-02 23:41  One thing that came to mind was an old problem with Unicode and Jet. You had to use VT_BSTRT instead of VT_BSTR to get anything - VT_BSTR is Unicode and if ANSI is expected the string will be empty (or only contain one letter). However, I'm not sure this is the problem, and it doesn't give any explanation for the DBTYPE_PROPVARIANT thing. Just my $0.02 Steen. Cheers Steen.

Bitmap.LoadBitmap(IDB_BITMAP); m_StaticBitmap.SetBitmap(Bitmap); ... BUT, the bitmap doesn't show on 98 SE WHY??? Re: Problem with CStatic SS_BITMAP Joaquín M López Muñoz19-Feb-02 2:54 Joaquín M López Muñoz 19-Feb-02 2:54  Is this bitmap of yours any rare? There are exceptional cases where a bitmap is correctly handled by NT/2000/XP and not by 98/ME (see MSDN info <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/bitmaps_1rw2.asp">BITMAPINFOHEADER</a>). If you suspect this to be the case, try replacing IDB_BITMAP with any other, standard bitmap.

Like class we can also inherit one structure from other. Like class we can also add public/private/protected members in struct. Like class we can also insert both data and functions in struct. SO WHAT IS THE MAIN DIFFERENCE BETWEEN CLASS AND STRUCTURE ????????? Samad khan Re: Difference between class and struct Tim Smith19-Feb-02 1:46 Tim Smith 19-Feb-02 1:46  One defaults to private (class) and the other defaults to public (struct). Other than that, there is no difference at all. Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Show modal window in taskbar. Pete Bassett19-Feb-02 1:44 Pete Bassett 19-Feb-02 1:44  I know the basic of this question is about VB but I figure I'm gonna have to use API to get what I want so I thought I'd post it here for the gurus to look at. Here goes... How do you force a modal form to show up in the taskbar. E.g. You have a bog basic VB Form named Form1 and a Sub Main which looks like this. Public Sub Main Form1.Show vbModal End Sub The fact that the form is modal means that it doesn't show up on the taskbar. I need it to show up on the task bar. Any ideas? API Welcome! Cheers Pete Re: Show modal window in taskbar. Michael P Butler19-Feb-02 2:03 Michael P Butler 19-Feb-02 2:03  This is a VB answer. A Form has a property called "ShowInTaskbar", set this to true and the form will appear in the taskbar Michael Re: Show modal window in taskbar. Pete Bassett19-Feb-02 2:10 Pete Bassett 19-Feb-02 2:10  Close, but no cigar. This property is overridden for modal forms... Pete Re: Show modal window in taskbar. Nish Nishant19-Feb-02 3:18 Nish Nishant 19-Feb-02 3:18  I think it's part of VB. Modal windows are treated differently I guess. You could do this though. CreateWindow a window and move it out of the desktop in your modal form's load function. Worth a try. When the modal form closes, destroy the window you created.
