Re: Problems with SymGetModuleBase Susto2-Jul-02 3:32 Susto 2-Jul-02 3:32  Hi John, thanks for your answer. What I like to know is when does it fail ? I'm using the method in already running product code and I cannot introduce a call to GetLastError. Regards Oli Re: Problems with SymGetModuleBase #realJSOP2-Jul-02 4:27 #realJSOP 2-Jul-02 4:27  Are you saying you don't have the source to the code? This is a symbolic debugger helper function.

I do this two things but when i print the bitmap,using StretchBlt, i get a white and black image. I think that the problem is that the DC i get from de printer, hdc2Bmp = CreateCompatibleDC(hdcPrinter);, has one bit per pixel. Who i can i change this? To get de printer dc i do this: if (!OpenPrinter((LPTSTR)m_szPrinterName,(LPHANDLE)&hPRN,NULL)) return FALSE; dpBytesNeeded = DocumentProperties(NULL,hPRN,(LPSTR)m_szPrinterName,NULL,NULL,0); if (!(lpDevMode = (LPDEVMODE)LocalAlloc(LPTR,dpBytesNeeded))) return FALSE; if (DocumentProperties(NULL,hPRN,(LPSTR)m_szPrinterName,(PDEVMODE)lpDevMode,NULL,DM_OUT_BUFFER) != IDOK) return FALSE; lpDevMode->dmOrientation = DMORIENT_LANDSCAPE; lpDevMode->dmCopies = m_iNumCopies; lpDevMode->dmFields = DM_ORIENTATION | DM_COPIES; if (DocumentProperties(NULL,hPRN,(LPSTR)m_szPrinterName,(PDEVMODE)lpDevMode,(PDEVMODE)lpDevMode,DM_IN_BUFFER|DM_OUT_BUFFER) != IDOK) return FALSE; if (!(hdcPrinter = CreateDC(m_szPrinterDriver,m_szPrinterName,NULL,(CONST DEVMODE *)lpDevMode))) return FALSE; Thanks Have a nice day Re: Print a bitmap trouble Mike Nordell2-Jul-02 6:43 Mike Nordell 2-Jul-02 6:43  A DC is initially created to contain a "default" b/w bitmap.

An app with GUI and CUI Janine1-Jul-02 20:51 Janine 1-Jul-02 20:51  Hello, I'm making an application, that should use console, when started from a command line and windows otherwise. It has to work in UNIX too, so it must have main(). The way I've done it, works, but I'm not satisfied with it. When I start it from a command line it works properly, but when starting it as GUI it makes a console window first and then GUI. I would like to get rid of the console in GUI version. I've tried to make console disappear using FreeConsole(), but even though I use it as early as possible the console flashes in the beginning. The other solution I've tried is to use linker options '/entry:"main" /subsystem:windows'. This works fine with GUI, but the console version doesn't do anything. I hope someone knows a better way to do it. -Janetta Re: An app with GUI and CUI Vuemme2-Jul-02 2:03 Vuemme 2-Jul-02 2:03  I think that the console creation is perfomed during the C library initialization that is performed by mainCRTStartup before your main function is called. You can found mainCRTStartup code into CRT0.C under /crt/src subdir of VC++ installation (if you installed the C library source code, of course). I never tried to remove the window (I looked at this code only to reduce the size of executables) but you can check the routines called during program startup. There's a good article about C library initialization by Matt Pietrek: http://www.microsoft.com/msj/defaulttop.asp?page=/msj/archive/s569.htm It explain how to reduce executable size but I think it could be helpful also for your pourpouses.

Seriously. The only way to get the stdio handles connected to the console starting the app is by having a main() and the app "tagged" as a console app by the PE flags (linker option /subsystem:console). This is one parts of the baggage we carry from Win16. The default behaviour for a console app to be started is that Windows (I don't know if its the module loader, but I guess it is) allocates a console for a console-tagged app. The only way I know about to change this is to change the flags passed to CreateProcess (to inhibit the creation of the console window). When you have an app that is started by another process (such as Explorer.exe when double-clocking an executable) I can only come to think of hooking (system-wide, loading your DLL for every created process and changing the import translation table) the CreateProcess call to stop it from doing this on a per-application basis. As I initially wrote, you're basically screwed. Sorry... Re: An app with GUI and CUI Janine3-Jul-02 19:37 Janine 3-Jul-02 19:37  Thanks for both of you for your advice.

Re: Just single instance of my app. Atlantys1-Jul-02 17:44 Atlantys 1-Jul-02 17:44  When the app starts up, do a check for a mutex. if it doesn't exist create one, and if not then find the existing app and restore it.. something like: CString strMutexName = _T("MyApp"); // can also use a GUID here if (!m_hMutex) { m_hMutex = CreateMutex(NULL, FALSE, strMutexName); } else { /* go through all the current windows and restore the existing version of your app. i can't remember how to do this now.. something to do with EnumWindow i'm sure, just don't use FindWindow (heard bad things about it ). */ } hope this helps.

Settlemier 2-Jul-02 3:23  sometimes its nice to pass off the command line from the second instance to the first. I usually do this with a control struct in shared memory. First instance creates the control struct and records its information there. Other instances, read the control struct and record their command line there, then activate the first instance, and notify it that their command line has been recorded before exiting. The first instance handles these as appropriate, perhaps opening another file, etc. how to delete a print job ? zhu1-Jul-02 17:21 zhu 1-Jul-02 17:21  Hi all, Here is a small description of my project: Users shall be able to send print jobs to a print server. On the print server, the print jobs arrived shallt be managed. My question/problem: I need to find a way to restrain a print job from being automatically printed when it arrives to the print server. I am thinking about using “FindFirstPrinterNotification” and “FindNextPrinterNotification” to catch “PRINTER_CHANGE_ADD_JOB” and then immediately ask the print job to delete. Is this the correct approach? Thank you, zhu xiao yun c++ sending a Message to OnDraw 1-Jul-02 17:17 1-Jul-02 17:17  Hello, I am using OpenDocument in the Doc class to Load in a DIB.

I'm turning into a grapefruit! How does ::MessageBox(...) work?? 1-Jul-02 15:08 1-Jul-02 15:08  Hey all. I'm not a newbie to Windows programming or multi-threading, but I've been wondering: how exactly does the implementation of ::MessageBox(...) work? I have a simple single-threaded application. I call ::MessageBox(...) somewhere in the code. The message box APPEARS to be blocking the code execution, since the line after the "::MessageBox(...)" will only be executed after the message box is dismissed. However, my single-threaded application is still processing messages! How is this magic performed behind the scenes? Thanks! Re: How does ::MessageBox(...) work?? Christian Graus1-Jul-02 15:28 Christian Graus 1-Jul-02 15:28  Probably because your message loop continues to process messages such as WM_PAINT. Christian I am completely intolerant of stupidity.

David Carkeet1-Jul-02 18:06 David Carkeet 1-Jul-02 18:06  Actually, Cristian (and correct me if im wrong) but i dont see how yr message loop can be working if yr appliaction has called message box... I think this is VERY good question for beginners like us. Im sure that messagebox domodal, etc. call a hoorrible nasty "PeekAndPump" type MS fudge. Any corrections? Dave Carkeet.

Actually, from memory it sets a flag for the app so that the window stops responding, but the message pump keeps right on pumping.
