Re: Convert MFC Doc / View App to a COM server basementman5-Mar-04 9:08 basementman 5-Mar-04 9:08  I hate to sound simplistic, but would using OutputDebugString() satisfy your needs? Or maybe you might want to look at Rob Manderson's Logging service.  onwards and upwards...  Re: Convert MFC Doc / View App to a COM server [EDITED] John M. Drescher5-Mar-04 9:22 John M. Drescher 5-Mar-04 9:22  I do already have a logging system (similar to Robs but not mfc). You may have sloved my problem. I could send a user message to the program from another app and have it spill the result in the log. Thanks. [EDIT] Now when I think of it the socket options do not seem very difficult. There was one other detail that was influencing my desire to have a COM server. I currently have several property sheets in a popup dialog in the main application (easter egg) that display most of this info. I was thinking that I could move the property sheet to the new application and use com/dcom to do the RPC / communications for me. [/EDIT] John Re: Convert MFC Doc / View App to a COM server [EDITED] basementman5-Mar-04 9:34 basementman 5-Mar-04 9:34  Glad to be of help. If you want to make it real simple, rather that doing the sockets implementation, simply have the app write out a file to a network shared folder that contains the tabbed dialog info (flattened out, of course) in response to an event. Your debugging program can then open and read that file. Or, you could implement another debugging socket like you said.  onwards and upwards...  Partial Editing in RichEditCtrl Rightoguy5-Mar-04 6:44 Rightoguy 5-Mar-04 6:44  I have a RichEditCtrl and in there we have the sql statement. What I am trying to achieve is have the RichEditCtrl act as a partial editing control where the user can type in certain areas and other place we have our reserved keywords which cannot be changed. Any Ideas or suggestion Vic Re: Partial Editing in RichEditCtrl James R. Twine5-Mar-04 7:17 James R. Twine 5-Mar-04 7:17  There is a protected character attribute that will send you EN_PROTECTED notifications on when the user tries to modify them. You can then take whatever action you need to. Lookup CFM_PROTECTED and EN_PROTECTED for more information.

First It is declarate like unsigned char, then is copy through memcpy to other struct unsigned char... See the code: #define AC__UCHAR unsigned char static AC__UCHAR temp1[256]; static AC__UCHAR fpData[512]; int storeFingerPrintData() { memcpy(fpData, temp1, sizeof(temp1)); //store data finger in smart card for (int j=0;fpData[j] !=0;) { int lbDataIn = 0; for (int k=0; k<32; k++) { memcpy(&apdu.bDataIn[k],&fpData[j],sizeof(AC__UCHAR)); lbDataIn++; j++; } // here I can see the values through AfxMessageBox(apdu.bDataIn); recNo++; }; return ret; } How I convert in a char* the variable apdu.bDataIn unsigned char and How is the best way-format for save it in any table of SQL Server.

Displaying data in an MDIChildWnd without a document slyone5-Mar-04 6:03 slyone 5-Mar-04 6:03  Hi, I've got some data and a message handler stored & controlled by the main frame of an MDI app, and would like to show the data in an MDIChildWnd. I can create a window with a standard child wnd OR my own child wnd. e.g. RECT pRect; pRect.top = 0; pRect.left = 0; pRect.bottom = 604; pRect.right = 394; m_pCamWnd = new CMyChildWnd; VERIFY(m_pCamWnd->Create( NULL, _T("Camera Input"), WS_CHILD | WS_VISIBLE | WS_OVERLAPPEDWINDOW, Rect, // this)); // (this was done in CMainFrame::OnCreate()). What I'm not sure about is, can I just derive my own class from CMDIChildWnd then override OnPaint() in order to actually output the data... My line of thinking being that CMDIChildWnd is derived from CFrameWnd which is derived from CWnd. So I'd really be overriding the OnPaint of it's 'grandparent'. Any advice on this would be greatly appreciated as I'm more than a little confused Dave PS sorry havin trouble gettin the [CODE] tags to work migrate nmae project to visual studio Anonymous5-Mar-04 5:37 Anonymous 5-Mar-04 5:37  Hello, I have a nmake file which compiles fine using (C++ ver 7) Visual Studio .NET Command Prompt. The nmake creates an exe which loads dll and uses virtual functions. I would like to add some functionality to this exe. However I cannot open the nmake file in Visual C++ as a project. There is no project file, just the cpp and h files and the nmake file and a some precompiled files. I have tried to recreate the files within a project but the errors are so many! I believe that dll files must be loaded at runtime, which appears to be something which is not happening?? Are there ways to do this?

How can i concate two bitmap to produce third combine bitmap Atif Mushtaq5-Mar-04 5:08 Atif Mushtaq 5-Mar-04 5:08  Hello guys can i combine two bitmaps to produce a third combined bitmap . for example if i have two images of 160*120 then resultant bitmap will of 320*240 size , which will be displaying two bitmaps side by side in on image . so can any body guide me how to do this. Unmanaged in a .NET world Re: How can i concate two bitmap to produce third combine bitmap Tom Larsen5-Mar-04 5:48 Tom Larsen 5-Mar-04 5:48  Wouldn't the resultant bitmap be 320 x 120? I'm also assuming the depth is the same on both. Allocate the size of the bitmap and use trusty old BitBlt. // leftDC and rightDC are the two drawing contexts on the images to combine. // memDC is the DC on the combination image. BitBlt(memDC,0,0,160,120, leftDC,0,0,SRCCOPY); BitBllt(memDC,161,0,320,120, rightDC,0,0,SRCCOPY); Visual C 6 Webbrowser &amp; Saving Webpages muckmail5-Mar-04 2:40 muckmail 5-Mar-04 2:40  Just wondering if the visual C6 webbrowser can archive files can be save in them *.mht format using Visual C6.

Either case, this should be at least 200MB a download. IDirectDraw4 is an interface which appeared in DirectX 7.

I want to handle when the user selects text with the mouse by pressing the left button. This works fine but when the mouse pointer is dragged belov or over the window the selections stops, which means that the user only can select text that is visible in the window. So I want to scroll when this happens. Does this make sense?
