tree controled options page w/o mfc? 10-Aug-01 8:36 10-Aug-01 8:36  Does anybody know how to make a tree controled options dialog, without mfc? Like the one in winamp? with a tree on the left that changes the dialog layout on the right with each selection... do they use property sheets? i've read the articles on this... but i don't want to use MFC! my app is written entirely in pure win32 api from the platform sdk. thanks, john Re: tree controled options page w/o mfc? Michael Dunn10-Aug-01 9:20 Michael Dunn 10-Aug-01 9:20  You start by making several modeless, borderless dialogs. When the selection in the tree changes, show the one dialog that corresponds to the selected tree node. The techniques in the MFC articles are applicable to you. Don't dismiss them just because they use MFC. --Mike-- http://home.inreach.com/mdunn/ "Make sure that if you are using a blow torch that you don't set anything on fire."   -- Chris Maunder compiler not recognizing dialog ID Jake Palmer10-Aug-01 7:44 Jake Palmer 10-Aug-01 7:44  Any ideas why the compiler is telling me it doesn't recognize the ID of the dialog that VC++ just created? I mean, I just made the resource for "IDD_DIALOG1", then created a new class for it, and when I try to build that class has an error in the generated .h file, at the line: enum { IDD = IDD_DIALOG1 } saying the ID is an undeclared identifier. that's lame. any ideas how to get rid of this? thanks, Jake Re: compiler not recognizing dialog ID Carlos Antollini10-Aug-01 7:56 Carlos Antollini 10-Aug-01 7:56  Check if in the resource.h header file you have that ID. And if in the header of your Dlg class you have the include of the resource.h Cheers!!!! Carlos Antollini. Re: compiler not recognizing dialog ID Jake Palmer10-Aug-01 8:49 Jake Palmer 10-Aug-01 8:49  The ID's are in resource.h, which is included only in my CWinApp-derived class. The app's header is included automatically in every cpp file in the project. So, when I compile the class in question, it picks up the include and works fine, but when I build the project, it apparently looks at the headers first and gives me trouble. should i include the app's header in the problem header, instead of in it's cpp file? Re: compiler not recognizing dialog ID Carlos Antollini10-Aug-01 9:38 Carlos Antollini 10-Aug-01 9:38  First. Try to include the header in the header of the class dialog. Second. Check if the value of IDD_DIALOG1 is correct, or if is dupplicated. If the problem persist, try to sen me the project by mail. Good luck!!!! Carlos Antollini. CDC ?? otvac10-Aug-01 4:56 otvac 10-Aug-01 4:56  I am using a printer outside the Framework. I declare a variable to hold a RecordSet Field: CString m_MyCString; I set the variable to the record set field: m_MyCString = m_pSet->m_MyStringField. All is OK so far. After I start the document: if (pDC.StartDoc(&pMyDoc)>0) { etc. } the CString variable m_MyCString gets changed to a different value. Duh!! Richard transparent listbox 10-Aug-01 4:50 10-Aug-01 4:50  i have set the transparent check box in the properties of the control but i still have a white background on the list control how can i make the list box trasparent or change all the background to the color of the dialog box. thank you Re: transparent listbox Tomasz Sowinski10-Aug-01 4:55 Tomasz Sowinski 10-Aug-01 4:55  Derive your own class from CListBox and handle WM_ERASEBKGND.

Re: transparent listbox Tomasz Sowinski10-Aug-01 6:34 Tomasz Sowinski 10-Aug-01 6:34  He also has to make it owner draw too, doesn't he? Have no idea - it depends how Windows draws items in the listbox. If DC has no TRANSPARENT bkmode set, he'll have to go ownerdraw. The easiest solution would be switching to CListCtrl and using CListCtrl::SetBkColor and CListCtrl::SetTextBkColor.

I want to get the Serialnumber of a Disk (Floppy Disk, Hard Disk (IDE & SCSI), CD,...) into a CString (- the disk where my program is saved). I've only found Source Code for IDE Hard Disks. Is there an API function to get the number. (There is one in VB.) Gerhard Re: Serialnumber of a Disk Tomasz Sowinski10-Aug-01 4:30 Tomasz Sowinski 10-Aug-01 4:30  Is there an API function to get the number.

If there is no current selection, the replacement text is inserted at the insertion point, that is, the current caret location. Tomasz Sowinski -- http://www.shooltz.com Re: Insert text to CRichEditCtrl/View Ray Kinsella10-Aug-01 3:23 Ray Kinsella 10-Aug-01 3:23  is it no something weird like, two carriage returns and then a line feed..... Regards Ray "Je Suis Mort De Rire" Re: Insert text to CRichEditCtrl/View 10-Aug-01 9:24 10-Aug-01 9:24  Can you please tell me what's wrong with this code: CMyRichEditView *pView; CRichEditCtrl& pCtrl = pView->GetRichEditCtrl(); pCtrl.ReplaceSel("\r\r\ntest"); I get a debug assertion in the third line. thanks Re: Insert text to CRichEditCtrl/View Jake Palmer10-Aug-01 9:36 Jake Palmer 10-Aug-01 9:36  I've never used a RichEditCtrl before, so I might be wrong, but it looks like you're declaring a pointer and never constructing it, so pCtrl is probably NULL or invalid somehow. Something like that Jake Re: Insert text to CRichEditCtrl/View 10-Aug-01 9:42 10-Aug-01 9:42  Yes, it seems to be NULL, by why? Re: Insert text to CRichEditCtrl/View Carlos Antollini10-Aug-01 9:50 Carlos Antollini 10-Aug-01 9:50  If you have a Assertion is because your code didn get the RichEditCtrl. In others words pCtrl is NULL. Do you really have the view of the richedit? Best Regards!!! Carlos Antollini. Re: Insert text to CRichEditCtrl/View 10-Aug-01 9:57 10-Aug-01 9:57  That's a good question. I thought this is the correct way to get the CRichEditCtrl of a CRichEditView. Re: Insert text to CRichEditCtrl/View Carlos Antollini10-Aug-01 10:07 Carlos Antollini 10-Aug-01 10:07  How you get the view of the richEdit? You made something like this? CRichEditCtrlView* pView = (CRichEditCtrlView*)GetDlgItem(IDC_RICHCTRL); I saw taht you get the view from a derived class or from your own class of RichEditView I think that the problem start there.... Carlos Antollini. Re: Insert text to CRichEditCtrl/View 10-Aug-01 10:27 10-Aug-01 10:27  NO, the other way round I want to get the control from my SDI-application, which has a CRichEditView class Re: Insert text to CRichEditCtrl/View 10-Aug-01 10:13 10-Aug-01 10:13  Have a look at the Wordpad example and all your problems will be solved. Question: What does pView point to???????? Exactly so how can you call GetRichEditControl? Re: Insert text to CRichEditCtrl/View 10-Aug-01 10:43 10-Aug-01 10:43  I think this is the problem. pView points into nothing I changed the code to CMyRichEditFTPView *pView = (CBMyRichEditDoc*)GetView(); CRichEditCtrl& pCtrl = pView->GetRichEditCtrl(); pCtrl.ReplaceSel("\r\r\nTest"); But the compiler says that GetView() ist an undefined expression (or something like that, I have the german visual c++), although it is defined in the MSDN as follows: CRichEditDoc::GetView I'm totally confused now
