Scott Leonard4-Feb-01 11:08 Scott Leonard 4-Feb-01 11:08  I am trying to get tooltips to work in a dialog application over a static control. In maindlg.h I declare: CToolTipCtrl ctipQStatus And in OnInitDialog: RECT rcTest; BOOL bTest = ::GetWindowRect(GetDlgItem(IDC_MGOOD), &rcTest); CToolInfo ctiTest(TTF_CENTERTIP, m_hWnd, IDC_MGOOD,&rcTest, "Tooltip Test"); HWND hwTest = ctipQStatus.Create(m_hWnd); bTest = ctipQStatus.AddTool(ctiTest); ctipQStatus.Activate(TRUE); Am I just completely missing how to use this? Thanks, sbl Selecting list control subitems Joe Moldovan4-Feb-01 5:50 Joe Moldovan 4-Feb-01 5:50  I am using an MFC CListCtrl with multiple columns. I have two related problems: 1. I can select an item (column 0) by left or right clicking on it but subitems don't respond when clicked. I would like to pop up a floating menu on any item or subitem when right clicked. 2. There seems to be no way that I can get the control to set the subitem attribute to selected (LVIS_SELECTED) and display blue. I have looked at SetItemState (no good, can't see subitems) and SetItem (does not work, just ignores the status change). Does anyone know how to make this SOB do as it is told and allow me to select a subitem? Has anyone done this without MFC using only the SDK API? Re: Selecting list control subitems Michael Dunn4-Feb-01 7:14 Michael Dunn 4-Feb-01 7:14  Make this call: yourListCtrl.SetExtendedStyle( yourListCtrl.GetExtendedStyle() | LVS_EX_FULLROWSELECT; Then, clicking anywhere in a row will select the whole row. This requires v4.70+ of the common controls. --Mike-- http://home.inreach.com/mdunn/ Time is an illusion; lunchtime doubly so. Re: Selecting list control subitems Joe Moldovan4-Feb-01 7:34 Joe Moldovan 4-Feb-01 7:34  A thousand blessings upon you! Works like a charm. (It's all there in the MSDN too. I must be getting old and blind.) custom compiler 4-Feb-01 0:49 4-Feb-01 0:49  Does anyone know how to setup MSVC 6 to use a custom compiler? For example, I might want to use gcc or the intel compiler... thanks Re: custom compiler Tim Deveaux4-Feb-01 4:33 Tim Deveaux 4-Feb-01 4:33  I tried the Intel compiler recently. They supply an addin (on the tools menu) which allows you to select the compiler to use. I had some problems switching between the two - the tool seems to modify the DSP to change the variables that point to cl.exe and link.exe to point to their intel counterparts, and it sometimes doesn't do a very good job of cleanup when you want to revert. The intel compiler, though, seems to honor all the VC settings flawlessly - doubt if gcc would. You might have to export the make file, change some .exe entries as above, then go from there - make files are not very portable.

VC++ and MS Word 3-Feb-01 21:04 3-Feb-01 21:04  I need to sent data from my application to MS Word and printing them there. What is the simplest way for doing this ? Re: VC++ and MS Word 6-Feb-01 23:30 6-Feb-01 23:30  i'm not expert for this but because of longer no-reply: open explorer, options, file types, microsoft word document, edit, print, edit and you will see what explorer makes all msdn examples i see are in vb what is not my domain maybe this helps you t! Using sndPlaySound() Vickie3-Feb-01 11:40 Vickie 3-Feb-01 11:40  Hi all, Do you know how to use the function sndPlaySound() in MFC? I had put it in my program, but it got an error. Is it any header file or other declaration is needed before calling this procedure? Thx for your help! Re: Using sndPlaySound() 3-Feb-01 12:38 3-Feb-01 12:38  sndPlaySound is obsolete, use PlaySound instead. Header: mmsystem.h. Library: winmm.lib. Re: Using sndPlaySound() Vickie3-Feb-01 18:04 Vickie 3-Feb-01 18:04  But do I need to declare anything else before calling this function, or any objects should be created first? Since I get "undeclared identifier" when calling this function. Thx a lot! Unsetting a database password 3-Feb-01 10:52 3-Feb-01 10:52  Hi All, My app uses a MS Access db that is password protected. I have a new requirement that I create a copy of the db that is not protected (I'm using DAO). Is there a way to unset the password of the copy from within VC++? I guess I can always build the copy from scratch (so the password isn't copied), but that would be a pain. Thanks.

Can I know if it is possible and how to declare and make it work?? Thx for your help! Re: 2D array of CString in MFC Joe Moldovan4-Feb-01 6:04 Joe Moldovan 4-Feb-01 6:04  Don't hate me but I don't think you can do it. I gave up after trying for a week. Currently I'm using linked CStringArray objects. Not neat but works. Re: 2D array of CString in MFC Vickie4-Feb-01 6:12 Vickie 4-Feb-01 6:12  Why I need to hate you that you gave me advice? ^v^! Anyway, can I know how to use CStringArray to construct a 2D array? Can you show me how to use and declare it? Thx for your sincere help! Re: 2D array of CString in MFC Michael Dunn4-Feb-01 7:19 Michael Dunn 4-Feb-01 7:19  You do it just like with any other type: CString myarray[20][10]; --Mike-- http://home.inreach.com/mdunn/ Time is an illusion; lunchtime doubly so. Re: 2D array of CString in MFC Joe Moldovan4-Feb-01 15:31 Joe Moldovan 4-Feb-01 15:31  I think I misunderstood something. (Read it at 4.30am so...) What I tried to do was a 2D CStringArray, derived from CStringArray, so that I could dynamicaly assign CString objects and have the array class allocate and clean up at run-time. I'm using "CStringArray fred[ 2 ]" at the moment. This is not neat at all as I said but works OK. I ass-u-med the original post was about this. Application behaves differently when using static/shared MFC linking 3-Feb-01 8:13 3-Feb-01 8:13  Hi Today I bumped into this. I'm working on an MFC app. When I link MFC statically, something goes wrong when the application terminates. A box comes up with "Memory 0x0000 0000 referenced 0x0000 0000, Memory could not be read", I can abort or debug. This only happends when linking statically to MFC. It doesn't matter which configuration I use, both debug and release behaves this way. I've tried to debug ofcourse. I can follow the execution out of WinMain, but not further. Any ideas? OnDaw and Scrolling 3-Feb-01 3:18 3-Feb-01 3:18  Hi, I have an application that draw numerous line of text in the main window (this text is drawing from a printing class that I want to send to the display device context). When I scroll the window, the lines of text are repeated (similar to a figure that is separated when we scroll). I have put in OnDraw functions like SetROP2 and SetTextColor with CLR_NONE. But I am not sur that is the good way. Anybody has suggestions ? Thanks Claude Re: OnDaw and Scrolling Christian Graus4-Feb-01 11:08 Christian Graus 4-Feb-01 11:08  You mean scrolling does not work ? You need to use GetScrollPosition() to position your text based on where the scroll bars are. Christian The content of this post is not necessarily the opinion of my yadda yadda yadda.

I've some question and i'm not sure if what i want is possible. Maybe you can help me. I want to create some very simple multithreaded environment for activex controls. I know there are the synchronization issues with multithreading but that will be a next step. For now even the basics doesn't seem to work with me. I want to created a container control. In design time it acts just like a normal activex container. You can put other activex controls on it. The container control can be hosted by an other container such as a VB form. In runtime it spans a CWinThread object and creates a window in that threat. The window is a child of the VBForm and a parent of the activex control container. Which makes the activex control and it's children running in a new thread. This is the theory I manage to create a window in a CWinThread object. I manage to put the window between the form and the activex control container. When i look with spy++, the window between the form and the container is running in a new thread as i expected. But the control container and it's controls are still running in the same thread of the VBForm. I used a override of the CreateControlWindow method of COleControl to reparent the control. Maybe this is way to simplistic. I also tried the ReparentControlWindow override with the same effect. Is it possible what i want ?? Is it more complicated then i at first thought ?? Are there hooks in the MFC control creation process that allow this ?? Do i've to create the controls dynamically from within the new threaded window ??
