Re: Custom control based on dialog Wim Jans12-Aug-02 5:35 Wim Jans 12-Aug-02 5:35  Thanks a lot. That did the trick! problem with propertysheetex toon12-Aug-02 2:58 toon 12-Aug-02 2:58  Hi. I am trying to create a wizard-style property sheet. I want to add header & watermark images to it. The header gets displayed, but the watermark does not appear. Here is the piece of code. HBITMAP hbm1, hbm2; hbm1 = LoadBitmap(::AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BMP1)); hbm2 = LoadBitmap(::AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BMP2)); m_ps.Construct("Options", NULL, 0, hbm1, NULL, hbm2); m_ps.m_psh.dwFlags |= (PSH_WIZARD97 | PSH_WATERMARK | PSH_USEHBMWATERMARK | PSH_STRETCHWATERMARK | PSH_WIZARDCONTEXTHELP | PSH_HASHELP | PSH_HEADER | PSH_USEHBMHEADER); I tried various combinations of the flags, but the watermark image is not getting displayed. Does this require some change to the property pages? ALso, I am unable to add header title/subtitle. I use VC++ 6.0 Can somebody guide me? Thanks. Logic is a systematic method of coming to the wrong conclusion with confidence. Access Database mysteries in VC++... Anonymous12-Aug-02 2:57 Anonymous 12-Aug-02 2:57  This is a complete mystery to me - ive opened an access database, and its only recognised 1 row: { CSoundFile* pSoundFile = new CSoundFile(); pSoundFile->Open(); CString tmp; tmp.Format("%d - %d ", pSoundFile->GetODBCFieldCount(), pSoundFile->GetRecordCount()); tmp += pSoundFile->GetTableName(); AfxMessageBox(tmp); } The messagebox outputs "2 - 1 [soundfilelookup]". However there are loadsa records in the database. Does anyone know what the problem is?? Re: Access Database mysteries in VC++... Stefan Pedersen12-Aug-02 3:21 Stefan Pedersen 12-Aug-02 3:21  If my memory serves me correct... The recordcount may not be accurate until EOF is seen (i.e. you have iterated through all records).

ReBars (urgent) Space Ace12-Aug-02 2:55 Space Ace 12-Aug-02 2:55  I've a ReBar in my SDI-Application and an Extended Combo Box in it. With the help of Class Wizard I select an existing class (CMainFrame) to be associated with the IDR_MAINFRAME resource of the rebar. In CMainFrame I create a OnSelChangeComboboxex1() function. It looks like this: CComboBoxEx *pCombo = (CComboBoxEx *)GetDlgItem(IDC_COMBOBOXEX1);<br /> int nSel = pCombo->GetCurSel(); etc. But the program fails because of some unhandled exception. I really don't know what the problem can be. Someone, please, help! Re: ReBars (urgent) Tomasz Sowinski12-Aug-02 3:02 Tomasz Sowinski 12-Aug-02 3:02  If this is really urgent, why can't you provide more information on 'some unhandled exception'? Is your combo a child of mainframe, or rather it's located on rebar? Tomasz Sowinski -- http://www.shooltz.com What is "scratch" and why can everything be made from it? Re: ReBars (urgent) Shog912-Aug-02 3:07 Shog9 12-Aug-02 3:07  Even though CMainFrame may be getting messages sent by it, the combobox is not actually a direct child. So GetDlgItem() is returning NULL, hence your crash. You'll need to obtain a handle to the ReBar window (this should already be a member of CMainFrame) and use that to obtain the combobox handle. --- Shog9 If I could sleep forever, I could forget about everything... Re: ReBars (urgent) Space Ace12-Aug-02 3:26 Space Ace 12-Aug-02 3:26  Thanks, I've got your idea. But how exactly should I obtain a handle to the ReBar window? (sorry, I'm just a beginner) Re: ReBars (urgent) Shog912-Aug-02 7:25 Shog9 12-Aug-02 7:25  It should be a member of your CMainFrame class. Probably it's called m_wndReBar. Note that the ReBar control itself only contains other windows, so it could contain the combo box itself, or the combo box could be on a dialog bar contained by the ReBar; i'm not sure how you set this up, so i can't say for sure. If you *are* using a dialog bar, there'll be another member of CMainFrame for that. Poke around a bit, it should all be clear. --- Shog9 If I could sleep forever, I could forget about everything... Re: ReBars (urgent) Space Ace12-Aug-02 9:27 Space Ace 12-Aug-02 9:27  Oh yeah, thanks, that helped, it turned out to be m_wndDlgBar Re: ReBars (urgent) Space Ace12-Aug-02 7:05 Space Ace 12-Aug-02 7:05  Please, help!! Help with Combo boxes Luis E. Cuadrado12-Aug-02 2:18 Luis E. Cuadrado 12-Aug-02 2:18  Hello: I need help with Combo boxes. I have a combo box in a dialog and I want to fill the combo box with some filenames of a specified directory. Then, after filling the combo box, I'm disabling it (it can be enable by a check box in the same dialog). The program complies and runs, and when I load the dialog with the combo box, when I click the check box to enable the combo box, there is nothing in it. This is the code snipet that I have in the ::OnInitDialog() event: ::SetCurrentDirectory(_T("C:\\sounds")); m_cbo.ResetContent(); m_cbo.Dir(DDL_DIRECTORY,_T("*.wav")); m_cbo.EnableWindow(FALSE); Is there something that I'm missing inthe combo box? What can I do to solve this? Any answer is more than welcome. Best regards, Luis E. Cuadrado ) Re: Help with Combo boxes Tomasz Sowinski12-Aug-02 2:39 Tomasz Sowinski 12-Aug-02 2:39  Change DDL_DIRECTORY to DDL_READWRITE.

Re: Help with Combo boxes Mike Upton12-Aug-02 2:41 Mike Upton 12-Aug-02 2:41  I've just looked at the sample code in the MSDN documentation, and it looks like you might need the DDL_READWRITE flag as well as the DDL_DIRECTORY flag: m_cbo.Dir(DDL_READWRITE | DDL_DIRECTORY, _T("*.wav")); I could be wrong though, I've never used CComboBox::Dir. If it still doesn't work, it might be worth checking the return value of the Dir function - it should be a positive value if everything's worked okay. If it returns zero, that means no files were added. A negative value indicates an error. "We are the knights who say Ni" (The Knights Who Say Ni) Re: Help with Combo boxes Luis E. Cuadrado12-Aug-02 4:25 Luis E. Cuadrado 12-Aug-02 4:25  Hello again: I edit the code. I tried using DDL_READWRITE | DDL_DIRECTORY and using just DDL_DIRECTORY and I wasn't able to see any files in the combo box. I click the little arrow of the combo box and nothing comes down. I wonder if is something related with the combo box. Any property that I have to change or something. What do yo guys think? Thanks for the replies, Luis E. Luis E. Cuadrado ) Re: Help with Combo boxes Tomasz Sowinski12-Aug-02 4:45 Tomasz Sowinski 12-Aug-02 4:45  Your combo may have very small dropdown area. In the resource editor, click on the combo box arrow, then resize the dropdown rectangle. Tomasz Sowinski -- http://www.shooltz.com What is "scratch" and why can everything be made from it? CWnd::FromHandlePermanent Nish Nishant12-Aug-02 1:39 Nish Nishant 12-Aug-02 1:39  My understanding of CWnd::FromHandlePermanent is this :- If there is an existing CWnd within the current application's heap/stack that currently holds the window with the passed window handle, then CWnd::FromHandlePermanent will return that CWnd*. But unfortunately that's not happening. It does return a permanent CWnd but it's not matching the original CWnd So is my understanding flawed or is this some kinda funny side effect of something else in my code?

FromHandlePermanent doesn't walk the stack or heap. It just checks the permanent map; permanent map gets new entries when you create objects derived from CWnd. It doesn't get updated when you call methods returning temporary CWnd's (like CWnd::FindWindow).

Re: CWnd::FromHandlePermanent Neville Franks12-Aug-02 1:58 Neville Franks 12-Aug-02 1:58  Hi Nish, Note that if you are using different threads then you won't see the CWnd* which is in one threads map in the other. Could this be the problem?

Can anyone suggest a good tutorial on this as most stuff on owner draw seems quite advanced. Thanks in advance. Elaine (fluffy tigress emoticon here) Would you like to meet my teddy bear ? Re: Beginners owner draw button Space Ace12-Aug-02 2:59 Space Ace 12-Aug-02 2:59  Well, there is a bit in "Programming VC++ 6.0" (Kruglinski, Wingo, Shepherd), Chapter 11, example 11D. In fact, there is an electronic variant of the book but it's a bit too large (about 11 Mb) Hope this helps. Re: Beginners owner draw button Shog912-Aug-02 7:29 Shog9 12-Aug-02 7:29  There are several nice articles on this site. You probably want to read through a couple of them before you get started, it shouldn't be too bad (most of the pain in doing custom or customized controls is dealing with backwards Windows crap...), so if you hit a specific problem you can always ask here. --- Shog9 If I could sleep forever, I could forget about everything...
