Status LPTPort : with CreateFile ? youssef16-Jul-01 5:31 youssef 16-Jul-01 5:31  Hi, I use CreateFile for use the Comport and LPT. With Comport : I would like to know how data is in the InputBuffer ? With LPTport : I would like to use Strobe, Init, Status, ... and How can I do for read and write a data in PCICard ? How can I do it ?

Best regards youssef display dialog 16-Jul-01 4:46 16-Jul-01 4:46  can somebody please help?!! what am i doing wrong here: CDialog m_wndSlider; m_wndSlider.Create(IDD_SLIDER_DLG,this); m_wndSlider.ShowWindow(SW_SHOW); the dialog wont display! (i am using cdialog instead of my CDialog derived class to eliminate these errors. ID_SLIDER_DLG is an empty dialog... thanks Re: display dialog Paolo Messina16-Jul-01 12:35 Paolo Messina 16-Jul-01 12:35  You are destroying the CDialog object. Since it's a modeless dialog, the MFC object should survive enough to show up. Either make it global or member of a class (maybe CWinApp?). Cheers, Paolo. Dependency File (.dep) Woes Derek Price16-Jul-01 4:43 Derek Price 16-Jul-01 4:43  Hello, We have an ActiveX control (T3Result.ocx) and we recently created a separate project dll (T3Resultfrares.dll) containing the French versions of our resource strings. However, everytime we build the ActiveX control, we get this message: Warning: cannot find "T3Resultfrares.dep" What is a .dep file? Can I re-create it to get rid of this warning? If not, can I do something to stop the message? Thanks in Advance!

Derek bitblt + Polygon Leon16-Jul-01 4:26 Leon 16-Jul-01 4:26  Hi , I need to bitblt some polygon - not rectangle ( i have it as CRgn ). Probably there's somewhere modified BitBlt function that looks similar to that [ccode] BOOL BitBltRegion( CDC* pDestDC, int ptVertex[0].x , int ptVertex[0].y , CDC* pSrcDC, CRgn reg, DWORD dwRop ); [/ccode] or somebody can give me a hint to write it myself I'd very happy to know , or probably there's another way ( masks ? ) Thank You in advance Re: bitblt + Polygon Tim Deveaux16-Jul-01 8:46 Tim Deveaux 16-Jul-01 8:46  I think what you might want to do is create a polygonal region equivalent to the polygon you want to blit, then select that region as the clipping region of your destination device context. If you blit the rectangle containing the polygon at the right coordinates after this clip region is set, it should to the trick. See CDC::SelectClipRgn. Re: bitblt + Polygon Leon16-Jul-01 21:13 Leon 16-Jul-01 21:13  Thank You , Tim , works great ! Just not to forget restore original clipping region after that .. Re: bitblt + Polygon Leon17-Jul-01 21:47 Leon 17-Jul-01 21:47  By the way , does it mean that if I want to work with DCs like with layers , when u don't see some parts of picture under topmost layer ( DC ) , u should do the same - use SelectClipRgn ? Re: bitblt + Polygon Tim Deveaux18-Jul-01 13:17 Tim Deveaux 18-Jul-01 13:17  Hmmm... don't know if I'd go that far - if you have a background DC that holds the entire screen, I'd just draw it on to that and blit a rectangle of whatever has changed to the screen DC. If you have layers, maybe I'd still combine them in the background before blitting. I posted a new article here that plays with this kind of stuff, but I'm not a games programmer so mine isn't going to be the best advice - I'm just trying to explore the mechanics at this stage. CSocket Assert problem 16-Jul-01 4:23 16-Jul-01 4:23  I have an MFC CSocket application in Win 95. During runtime when I send data through the socket an ASSERT fails in the file sockcore.cpp at line 755, which reads: ASSERT(m_hSocket == INVALID_SOCKET || CAsyncSocket::FromHandle(m_hSocket) != NULL); When I ignore the error my data arrives just fine at the other end of the connection. Where does this error come from and how do I suppress it? Thank you LP LP how to adjust the line length of the debug window in vc6? Patrick Hoffmann16-Jul-01 3:28 Patrick Hoffmann 16-Jul-01 3:28  Hi folx! Does anybody know a way to adjust the line length in the debugging output window of vc6? thnx a lot.

Hadi Rezaee16-Jul-01 3:08 Hadi Rezaee 16-Jul-01 3:08  Hi all, I have question about data types ... I want to know, does UINT variable is equal with long variable ? I mean is size ?

Please visit in: www.geocities.com/hadi_rezaie/index.html Hadi Rezaie Re: UINT == long ??? #realJSOP16-Jul-01 3:19 #realJSOP 16-Jul-01 3:19  Yes. Re: UINT == long ??? mr200316-Jul-01 4:29 mr2003 16-Jul-01 4:29  Yes Ehsan Behboudi Re: UINT == long ??? Michael Dunn16-Jul-01 10:31 Michael Dunn 16-Jul-01 10:31  A UINT is absolutely not the same as a long. They're the same size, 4 bytes, but UINT is unsigned, whereas long is signed. Also, the sizes may change in future versions of the compiler. --Mike-- http://home.inreach.com/mdunn/ Sometimes, arming yourself with a big pointy stake just won't do you any good. Re: UINT == long ??? #realJSOP17-Jul-01 1:42 #realJSOP 17-Jul-01 1:42  His question was whether or not they (a UINT and a long) were the same size. Yes, they are the same size (in our 32-bit world of VC6). They were not the same size as a long in 16-bit, but who does 16-bit any more? Re: UINT == long ??? Patrick Hoffmann17-Jul-01 6:48 Patrick Hoffmann 17-Jul-01 6:48  UINT is defined as unsigned int. The int type is different on different machine types. On Windows 32 bit it is 32 bits wide. long is well defined as a 32-Bit signed value on all machines. So int is not long! and UINT equals a unsigned long on a 32-Bit architecture. So on such a machine long equals UINT in that way, that both uses 32 bit (4 bytes). But long uses the highest bit for the +/- sign instead of UINT that has no sign.

I have a bunch of files, and I like to use this function to open the files. and each file has to be in a new document. Thanks Ehsan Behboudi Re: Opening a new document by passing the file name in CView class. Ben Burnett16-Jul-01 5:20 Ben Burnett 16-Jul-01 5:20  You can use AfxGetApp()->OpenDocumentFile( "filename.ext" ); -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Re: Opening a new document by passing the file name in CView class. mr200316-Jul-01 6:33 mr2003 16-Jul-01 6:33  Thanks for you reply,, the filePathName that I pass to the OpenDocumentFile( FilePathName) is a Bitmap, it opens an epmty document,, Can you have a look at my code Please.. Thanks //My application is MDI, and I store a bunch of bitmap pathNames in the // first docuemnt, pFirstDoc is a pointer to that document. pApp->OpenDocumentFile(pFirstDoc->m_filePathArray.GetAt(0)); CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd; // Get the active MDI child window. CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame(); // or CMDIChildWnd *pChild = pFrame->MDIGetActive(); // Get the active view attached to the active MDI child // window. CTurboMechView *pView = (CTurboMechView *) pChild->GetActiveView(); pView->LoadBitmap(pFirstDoc->m_filePathArray.GetAt(0)); pView->OnPaint(); Any ideas??? Thanks Ehsan Behboudi Re: Opening a new document by passing the file name in CView class. Ben Burnett16-Jul-01 9:29 Ben Burnett 16-Jul-01 9:29  What is the problem that you are experiencing? BTW: Just curious; > pApp->OpenDocumentFile(pFirstDoc->m_filePathArray.GetAt(0)); [snip] > pView->LoadBitmap(pFirstDoc->m_filePathArray.GetAt(0)); Why load the bitmap twice? Maybe I dont understand what your doing, but when you call OpenDocumentFile does this not load the bitmap in your document? -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Re: Opening a new document by passing the file name in CView class. mr200317-Jul-01 2:32 mr2003 17-Jul-01 2:32  When I call OpenDocumentFile, it only opens a blank document. It doesn't display the bitmap. but when I load it with my pointer to CView, it still won't display the bitmap. any ideas? Ehsan Behboudi
