Re: Blinking label. Christian Graus23-Jul-01 12:15 Christian Graus 23-Jul-01 12:15  Set up a timer and call ShowWindow(SW_SHOW/SW_HIDE) on alternate calls. I'd override the static control and make it nice and internal. Then you can use it over and over.

John Uhlenbrock24-Jul-01 7:12 John Uhlenbrock 24-Jul-01 7:12  I'm not quite sure how I should do this. I need it to blink, while the the rest of the application keeps running...which means I need to have a seperate thread for the blinklabel? Re: Blinking label. Christian Graus24-Jul-01 10:46 Christian Graus 24-Jul-01 10:46  Not at all. Have you not used WM_TIMER before ? There is a tutorla here on how it's done, but the essence of it is on startup: SetTImer(42,1000,NULL); in OnTimer if (nIDEvent==42) // I may have the variable name wrong ;0) { m_bFlash = !m_bFlash; // You need to create this m_MyStatic.ShowWindow(m_bFlash ? SW_SHOW : SW_HIDE); } Christian #include "std_disclaimer.h" The careful application of terror is also a form of communication. Eagles may soar, but weasels don't get sucked into jet engines. Why my four radio buttons show up but no text next to them? tm23-Jul-01 10:39 tm 23-Jul-01 10:39  I am creating these four radio buttons dynamically. The behavior is so random and confusing. At some point I got some text, and then I can't get it anymore. I have been told by friends at this forum that maybe the width is not enough, one time that fixed the problem but not anymore!!!!!!! Here is the code: if (OneGrpPosition != NULL) { pConfig->m_OneRadioBtn = (CRadioBtn *) (((CGrpBox*)pConfig->m_OneGrpBox)->m_GrpRadioBtn).GetNext(OneGrpPosition); int len= ctrlRect.right - ctrlRect.left; ctrlRect.right = ctrlRect.left +len+ 60; if (ctrlRect.right >= 542) ::MessageBox(0, "Running out of screen width to display radio button", "Warning", MB_OK); ctrlRect.bottom = ctrlRect.top + 25; if (nDex == 0) // { m_RadioButtonArray[nDex].Create((pConfig->m_OneRadioBtn)->m_RadioLabel, WS_GROUP | WS_CHILD | WS_VISIBLE | BS_AUTORADIOBUTTON, ctrlRect,this, (pConfig->m_OneRadioBtn)->m_RadioGuiID ); m_RadioButtonArray[nDex].SetFont(&m_font, TRUE); } else { m_RadioButtonArray[nDex].Create((pConfig->m_OneRadioBtn)->m_RadioLabel,WS_CHILD| WS_VISIBLE | BS_AUTORADIOBUTTON, ctrlRect,this,(pConfig->m_OneRadioBtn)->m_RadioGuiID); m_RadioButtonArray[nDex].SetFont(&m_font, TRUE); } nDex= nDex+1; ctrlRect.left = ctrlRect.right +10; //This radio button has already been added to the memory structure } } //This ia a new radio button that needs to be added to the memory structure } I am in Paradise.

Re: Why my four radio buttons show up but no text next to them? tm23-Jul-01 12:32 tm 23-Jul-01 12:32  top=35 bottom=60 L=120 R=220 I have tried L=120 and Right = 170 through 220. It is really confusing. Thanks for your time I am in Paradise. Voltaire Re: Why my four radio buttons show up but no text next to them? Paolo Messina23-Jul-01 12:37 Paolo Messina 23-Jul-01 12:37  Are you sure the radio buttons gets created? Can you see the dot? the if clause in your code is doing the same for both conditions... why? Re: Why my four radio buttons show up but no text next to them? 23-Jul-01 14:53 23-Jul-01 14:53  Yes, I see all my four radio buttons are being created. The first one is different from the other three, because I need to have them in a group. Meaning if I click on of them the other three are unselected. I do see the four of them being created. But no text next to them. I am thinking of just creating the first one to see if the text displays there. It is a weird one. I really am looking forward to solve this one!! Thanks again for your time. Re: Why my four radio buttons show up but no text next to them? Paolo Messina24-Jul-01 3:41 Paolo Messina 24-Jul-01 3:41  It's very weird, but to my experiece this kind of bugs are really stupid. Did you tried to use a hard-coded CRect for the creation, just to make sure it's not something else? However, if you would send me a small demo project, I'll give it a look. I hate this kind of bugs! Paolo. Monitoring Clipboard 23-Jul-01 9:56 23-Jul-01 9:56  Hi, Is there a way that I can monitor all the operations in the clipboard(Copy/Cut - that happens on any application) and get notifications. Thanks, Ganesh.M.Ramaswamy Ganesh.M.Ramaswamy Re: Monitoring Clipboard Michael Dunn23-Jul-01 10:28 Michael Dunn 23-Jul-01 10:28  See my article ClipSpy for an app that monitors the clipboard. --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 Initial Update in CDialog 23-Jul-01 9:12 23-Jul-01 9:12  I have a progress bar in a CDialog and I want to step it as soon as the dialog becomes visible. I can't do that in InitDialog, because the dialog is not visible yet. Where would I do that? Thank You XP Re: Initial Update in CDialog Chris Losinger23-Jul-01 9:24 Chris Losinger 23-Jul-01 9:24  how about OnShowWindow ? -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com A simple question... 23-Jul-01 9:11 23-Jul-01 9:11  I've begun to learn VC (MFC) few days ago. i want to make something using the "ExtractIcon()" function. the first paramter of this function (as written in MSDN) is a handle to instance of the application. How the hell do i get this handle? what should i send him as this first parameter? thanks a lot RG Re: A simple question... Chris Losinger23-Jul-01 9:23 Chris Losinger 23-Jul-01 9:23  Call AfxGetInstanceHandle -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com I've tried it but... 23-Jul-01 12:35 23-Jul-01 12:35  look at this code: ... HICON icon = ExtractAssociatedIcon(AfxGetInstanceHandle() , "D:\\file.fp", 0); ASERT(icon==NULL) static.Create(NULL, WS_CHILD|WS_VISIBLE|SS_ICON|SS_CENTERIMAGE, CRect(10,10,150,50), this); static.SetIcon(icon); ... static is CStatic variable. i dont know why, but this code causes an error, the windows error message: "illigal operation" appears. and it happens only after i use this function.... have any ideas? thanks RG Re: I've tried it but... Paolo Messina23-Jul-01 12:45 Paolo Messina 23-Jul-01 12:45  Do you mean ASSERT(icon != NULL) ? Re: I've tried it but... Andrew Peace23-Jul-01 13:05 Andrew Peace 23-Jul-01 13:05  As above about ASSERT; ASSERT(icon != NULL); And also, the icon variable has to be present for the lifetime of the static control - thus you must put it as a member variable of the class, or as a global variable. > Andrew. Re: I've tried it but... Reid23-Jul-01 13:37 Reid 23-Jul-01 13:37  You know, you COULD put it as a global variable... but then again, we also COULD write poor poor poor code... If I were you, i would stick to putting it as a member variable of the Document class or the View class...depends on how it is used... -Reid the C++/C# programmer (Caution: I am a teenager, and that means that I think I know everything...but probably don't...) Re: I've tried it but... Andrew Peace23-Jul-01 13:44 Andrew Peace 23-Jul-01 13:44  Yes you're right about the global variable (obviously) but I said that because....hmmmm....don't know why I said that. You're right - it should be a member of the class that's using it. Truth be told, the reason I said global variable was because I thought maybe he wasn't doing OOP programming, in which case that's pretty much the only alternative. > Andrew. Re: I've tried it but... 23-Jul-01 23:19 23-Jul-01 23:19  you were right about the ASSERT parameter, but still, i dont understand why i get this error message, and it happens only because i used the AfxGetInstanceHandle() function. Please heeelp! thanks. Movable toolbar buttons Jake Palmer23-Jul-01 8:58 Jake Palmer 23-Jul-01 8:58  How can I create a toolbar whose buttons can be rearranged by drag/drop without needing to hold down any keys? Also, another question: in VC++ 6, why can't I create a new MFC class that derives from CToolBar, only from CToolBarCtrl? I've gotten around this by creating the ToolBarCtrls and then changing the inheritance myself, which I don't think ClassWizard is too fond of. thanks, Jake Re: Movable toolbar buttons Paolo Messina23-Jul-01 12:52 Paolo Messina 23-Jul-01 12:52  I can't answer to the first question, sorry. As for the second... it's just what I did two days ago and it works well. May this could comfort you After you replaced each occurence of CToolBarCtrl with CToolBar, make sure you delete the .clw file and start ClassWizard to create a new one. Paolo. makefile file format Nikhil Dabas23-Jul-01 8:35 Nikhil Dabas 23-Jul-01 8:35  Hi gurus, Could somebody point me to some documentation for writing makefiles for use with nmake? Everybody seems to use thaem but I cant find any documentation...
