How convert unsigned char[] to *char Joe_Valenz5-Mar-04 6:18 Joe_Valenz 5-Mar-04 6:18  Hello:I am working a biometric project, my problem is now that I need save the native finger data format in SQl Server Data Base format compatible (varchar). 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. Thanks and Regards. Joe.

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? Any thoughts are appreciated. files: http://www.geocities.com/stashfiles/win_vc6_mak.txt http://www.geocities.com/stashfiles/mediasinkencoder_cpp.txt http://www.geocities.com/stashfiles/mediasinkencoder_h.txt http://www.geocities.com/stashfiles/main_cpp.txt http://www.geocities.com/stashfiles/guids_cpp.txt extracted from: https://producersdk.helixcommunity.org/ docs/producer_sdk_files.htm Re: migrate nmae project to visual studio Anthony_Yio5-Mar-04 22:35 Anthony_Yio 5-Mar-04 22:35  Probably Borland C++ builder has the feature.

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.

At some point, it may need to lock volumes or files for processing but sometimes these files/volumes will be in use by other processes. This tool is meant to get top priority when it is run. Is there a way if can take over files/volumes that are in use by other processes? Mark How I show the *.mdb table content on the form?

Either case, this should be at least 200MB a download. IDirectDraw4 is an interface which appeared in DirectX 7. Re: How to compile DirectX in MFC includeh105-Mar-04 11:31 includeh10 5-Mar-04 11:31  nothing about sdk. it can be compiled in win32 app. includeh10 Text selection in CRichEditView MolleX4-Mar-04 23:40 MolleX 4-Mar-04 23:40  Hi, I have a CRichEditView derived class. 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? Regards Re: Text selection in CRichEditView includeh105-Mar-04 0:34 includeh10 5-Mar-04 0:34  use SetCapture() on LButton down and ReleaseCapture() on LButton up includeh10 Re: Text selection in CRichEditView MolleX5-Mar-04 0:50 MolleX 5-Mar-04 0:50  Thanks that seems to do the trick. Do you know how to handle ctrl-key input? I can get when the user press ctrl and when a user press another one. Do I need to keep track if the ctrl is pressed or is there a predefined way to do that, multiple key input? Cheers Re: Text selection in CRichEditView includeh105-Mar-04 0:54 includeh10 5-Mar-04 0:54  use GetKeyboardState() in key down and char down messages. includeh10 Re: Text selection in CRichEditView MolleX5-Mar-04 1:19 MolleX 5-Mar-04 1:19  Thanks again Philips API samrenkazi4-Mar-04 23:29 samrenkazi 4-Mar-04 23:29  Did any body had work on Philips SpeechSDK C/C++ API. if ues then plz let me know Ping!!!!
