change text color in a combo box 31-Jul-01 6:34 31-Jul-01 6:34  I have created a onctlcolor function to change to text color of my controls. but i can not change the text color in the combo box. Is there another funtion to do this? Thank you Problem with Cristi Posea's CSizingControlBar Jamie Nordmeyer31-Jul-01 6:20 Jamie Nordmeyer 31-Jul-01 6:20  I have (so far) a default MDI app with a CSizingControlBarG derived bar docked on the left side of my frame. Since it's the default MDI implementation (the one created by AppWizard), I have a menu, one toolbar, and a status bar. When I begin a resize operation on the control bar, the splitter shows up as it should, but is drawn on top of the toolbar, and doesn't go all the way to the status bar. So, the splitter is the correct length, but it's shifted up by the height of the toolbar (seemingly). How do I fix this, so it draws from the bottom of the toolbar (instead of over it) down to the status bar? Thanks in advance.

It works fine with all but the combo box. Can the text color of a combo box be modified? If so how can it be done? Thank you Sending Messages 31-Jul-01 5:05 31-Jul-01 5:05  I am trying to send messages to a process I created using CreateProcess(). For the send function I need a HWND handle of the process' main Window. How can I optain this handle from what I know after calling CreateProcess()? LP Re: Sending Messages Tomasz Sowinski31-Jul-01 9:16 Tomasz Sowinski 31-Jul-01 9:16  There's no general method for that - CreateProcess can spawn the windowless process, after all. You should use WaitForInputIdle with handle of the child process to give it a time to create its main window, and FindWindow to get the HWND of this window. You'll need the window class name, use Spy++ if you don't know what's the class name.

Nothing heavy computationally, just very focussed on a customers needs. I now need to apply what I have done in such a way that it can be wrapped by an ActiveX control. Aside from buying a good book, that I naturally intend to do, can anyone tell me if it possible to reuse the CView derived class Any pointers would be greatly appreciated to get me going until the book arrives... Matthew Re: ActiveX CView and OpneGL Not Active31-Jul-01 15:35 Not Active 31-Jul-01 15:35  Yes you should be able to reuse this by wraping it in a MFC ActiveX. The book would be the best to help you, I like to avoid using MFC and ActiveX in the same sentence. Damn! Did it twice.;) Re: ActiveX CView and OpneGL Jonathan de Halleux30-Oct-01 1:14 Jonathan de Halleux 30-Oct-01 1:14  Check this site: http://www.wzw.tu-muenchen.de/~syring/ActiveX/ Jonathan de Halleux, Belgium. Statusbar icon 31-Jul-01 4:10 31-Jul-01 4:10  Does anyone know how to load an icon into the statusbar without using MFC ? I need this to a COM server in wich I'm not using MFC. thanx /John Re: Statusbar icon Tomasz Sowinski31-Jul-01 4:16 Tomasz Sowinski 31-Jul-01 4:16  Use SB_SETICON message. Tomasz Sowinski -- http://www.shooltz.com Re: Statusbar icon 31-Jul-01 4:56 31-Jul-01 4:56  Do you know of any examples on this, I don't seem to be clever enough to get it running with the explanation of SB_SETICON in MSDN : ), at least not yet that is. Re: Statusbar icon Tomasz Sowinski31-Jul-01 5:04 Tomasz Sowinski 31-Jul-01 5:04  I don't seem to be clever enough to get it running with the explanation of SB_SETICON in MSDN Hmmm... That's a real problem. Which part of the explanation you don't understand? Tomasz Sowinski -- http://www.shooltz.com Re: Statusbar icon 31-Jul-01 22:22 31-Jul-01 22:22  I don't know how to create a handle to my icon. I hope I made it clear that I want to create the icon in the "taskbar statusbar". Just left of the clock that is. In MSDN I found something called Shell_NotifyIcon is this perhaps what I should use ? Thanks for helping me out ! /John Re: Statusbar icon Tomasz Sowinski1-Aug-01 2:34 Tomasz Sowinski 1-Aug-01 2:34  I don't know how to create a handle to my icon LoadIcon I hope I made it clear that I want to create the icon in the "taskbar statusbar" Quite the opposite - you asked for icon in statusbar. Statusbar != taskbar. There's no such thing as "taskbar statusbar" (however, it would be pretty good name for pub visited by developers) In MSDN I found something called Shell_NotifyIcon is this perhaps what I should use Yes. Tomasz Sowinski -- http://www.shooltz.com Re: Statusbar icon 1-Aug-01 3:39 1-Aug-01 3:39  Seems like I got it wrong, what I ment was Taskbar Status Area. I have gotten so far that I can create default icons (100-105), but still not the ones that I create. I assume that I don't use LoadIcon correctly. Re: Statusbar icon Tomasz Sowinski1-Aug-01 5:51 Tomasz Sowinski 1-Aug-01 5:51  I can create default icons (100-105) What do you mean by 'default icons' (100-105)? The predefined icons (the ones with IDI_ prefix) have numeric identifiers well above 32000. Tomasz Sowinski -- http://www.shooltz.com Re: Statusbar icon 1-Aug-01 20:41 1-Aug-01 20:41  If I call MAKEINTRESOURCE(101), i get a yellow warining triangle. Numbers 100-105 shows Icons, the others that I have tryed are empty. My own Icon is defined in the resource.h #define IDI_ICON1 101 In the .rc file the icon is defined like this: IDI_ICON1 ICON DISCARDABLE "MyIcon.ico" But if I make the call LoadIcon(g_hInstance, MAKEINTRESOURCE(IDI_ICON1) ) an empty space will show. I have tryed to change the define to some other number and call that number with MAKEINTRESOURCE. That also creates empty space.

I am using VC++ 6.0. I am trying to add the CxShadeButton class, that is posted on this site, in to my project. I tried the 4 steps listed in the source code but keep receiving "Program termination error message". When I exit C++, I then get the blue screen. Any input would be appreciated. I did download the demo and it worked great. Thank you. Annette mailto:mannette@gte.net Resizing Property Pages Derek Lakin31-Jul-01 3:18 Derek Lakin 31-Jul-01 3:18  I have a modeless property sheet class derived from CPropertySheet to provide a dialog box with a tabbed control on it. I want to add some controls above the tabbed part. Where do I need to handle this (OnCreate, OnInitDialog, etc.)? And how do I implement it? I have tried using GetWindowRect for AFX_IDC_TAB_CONTROL (or whatever the ID is) and then using MoveWindow but it always seems to put the origin at the top left of the dialog. Thanks, Derek.

Hadi Rezaee31-Jul-01 2:35 Hadi Rezaee 31-Jul-01 2:35  Hi all, My recordset is open: m_rs->Open(dbOpenDynaset, "SELECT * FROM PERSON"); . . . Now, i need query on the Person table, so i have two way: Way 1: Using of m_strFilter: m_rs->m_strFilter = "[NAME] = 'Ali'"; m_rs->Requery(); Way 2: Using closing and then opening again: m_rs->Close(); m_rs->Open(dbOpenDynaset, "SELECT * FROM PERSON WHERE [NAME] = 'Ali'", dbForwardOnly | dbReadOnly); What is your idea ? which is faster for my query ?

The general rule should be to always do a requery to cut the overhead of destruction and construction of your recordset... Remember that this happens TWO places... in your app and on the database engine. So you generally want to modify the filter and requery... EXCEPTION: There are times, on certain DB engines when using a Filter sets up a read only recordSet.... regardless of the MFC Documentation. In cases where you require edit or add using the filter can produce 'Recordset is not updateable' or a message to that effect!
