Tommy Svensson1-Jul-02 23:45 Tommy Svensson 1-Jul-02 23:45  Hi again, IE has a field of standard buttons. Is it possible to add a button to that field and attach some code to it to be invoked when the button is pushed? Thx a lot, /Tommy Reacting to a text selection in IE...? Tommy Svensson1-Jul-02 23:43 Tommy Svensson 1-Jul-02 23:43  Hi everybody, I wish to perform some action on a piece of selected text, grabbed from within IE. So, when for example double clicking a word in explorer, the word gets selected. Immediately I would like my code to execute to perform some nifty action. Does anyone know how to accomplish this, any pointers? Seems like a difficult task, but is it really? /Tommy bitmap write problem SilentWarrior1-Jul-02 22:26 SilentWarrior 1-Jul-02 22:26  hi .. i want to write a bitmap to a file , the code which ive written is BOOL COpenbitmapDlg::WriteDIB(LPTSTR szFile, HANDLE hDIB) { //---------------------------------------- BITMAPFILEHEADER hdr ; LPBITMAPINFOHEADER lpbi ; if(!hDIB) return FALSE ; CFile file ; if(!file.Open(szFile,CFile::modeWrite|CFile::modeCreate)) return FALSE ; lpbi=(LPBITMAPINFOHEADER)hDIB; int nColors = 1 << lpbi->biBitCount; hdr.bfType = ((WORD) ('M' << 8) | 'B'); // is always "BM" hdr.bfSize = GlobalSize (hDIB) + sizeof( hdr ); hdr.bfReserved1 = 0; hdr.bfReserved2 = 0; hdr.bfOffBits = (DWORD) (sizeof( hdr ) + lpbi->biSize + nColors * sizeof(RGBQUAD)); file.Write( &hdr, sizeof(hdr) ); // Write the DIB header and the bits file.Write( lpbi, GlobalSize(hDIB) ); //file.WriteHuge(lpbi,GlobalSize(hDIB)): return TRUE; } and then i pass it a bitmap handle which i use to open simple bitmap files. this code do create a file .. but when i try to check dat file i get an error message , secondly the file size is also very much less than the orignal file. looking for ure hlp looking forward from all the gurus of code Re: bitmap write problem Davide Pizzolato1-Jul-02 22:51 Davide Pizzolato 1-Jul-02 22:51  try: BYTE* pDib = (BYTE*)GlobalLock(hDIB); replace hDIB with pDib and call GlobalUnlock(pDib); at the end.

How can I read line to line with CFile Class? 1-Jul-02 21:53 1-Jul-02 21:53  My problem is that I can not compare the character 13 which is carriage return and the character 10 newLine. I attemp to do f.e char buffer[10]; if ((buffer[ct]==\13)||(buffer[ct]==\10)) too I have attempt: if ((buffer[ct]==0x0D)||(buffer[ct]==0x0A)) also if ((buffer[ct]==char(13))||(buffer[ct]==char(10)) but any other way it works fine. I don´t know why it is the cause. The program entry not for this way. thanks in advance. Re: How can I read line to line with CFile Class? Nish Nishant1-Jul-02 22:41 Nish Nishant 1-Jul-02 22:41  If you want to read line by line, use CStdioFile instead of CFile and call CStdioFile::ReadString which reads a line of text Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW] Re: How can I read line to line with CFile Class? Roger Allen1-Jul-02 22:52 Roger Allen 1-Jul-02 22:52  To do character comparisons you would use: '\r' , '\n' or '\016' (13) or '\013' (10) octal Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one. Re: How can I read line to line with CFile Class? Christian Graus2-Jul-02 13:07 Christian Graus 2-Jul-02 13:07  If you use iostreams, then GetLine will work perfectly and you can even set the delimiter.

Thanks Oli Re: Problems with SymGetModuleBase #realJSOP2-Jul-02 3:24 #realJSOP 2-Jul-02 3:24  If the function succeeds, the return value is a nonzero virtual address. The value is the base address of the module containing the address specified by the dwAddr parameter. If the function fails, the return value is zero. To retrieve extended error information, call GetLastError. ------- signature starts "...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001 Please review the Legal Disclaimer in my bio. ------- signature ends Re: Problems with SymGetModuleBase Susto2-Jul-02 3:32 Susto 2-Jul-02 3:32  Hi John, thanks for your answer.

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. I haven't found a solution yet, but I'll keep on fighting -Janetta
