I'll provide a few links to get you started. Storing "Paint Brush" images in a Access DB[^] Embedding OLE Objects Into an Access Database [^] I should write a note to remind me to write an article about this stuff. I seem to be too tho.

Thanks for all the input, ns serial communication and bluetooth Frank S.7-Aug-02 6:28 Frank S. 7-Aug-02 6:28  Hi, I have a problem ... i have written a program that communicates with IR - serial communication with my pocket pc and my mobile phone. I used for that a part of the little tty-codesample, which you can find in the help of the Visual C++ tools of Microsoft. I changed there some communication options and it worked. But now i want to use that serial communication with bluetooth. Could that work? And one thing is, that i don't know exactly, how i have to setup the settings for that communication (serial). My current setup is like that: PortDCB.BaudRate = CBR_9600; PortDCB.fBinary = TRUE; PortDCB.fParity = TRUE; PortDCB.fOutxCtsFlow = FALSE; PortDCB.fOutxDsrFlow = FALSE; PortDCB.fDtrControl = DTR_CONTROL_ENABLE; PortDCB.fDsrSensitivity = FALSE; PortDCB.fTXContinueOnXoff = TRUE; PortDCB.fOutX = FALSE; PortDCB.fInX = FALSE; PortDCB.fErrorChar = FALSE; PortDCB.fNull = FALSE; PortDCB.fRtsControl = RTS_CONTROL_ENABLE; PortDCB.fAbortOnError = FALSE; PortDCB.ByteSize = 8; PortDCB.Parity = NOPARITY; PortDCB.StopBits = ONESTOPBIT; and: CommTimeouts.ReadIntervalTimeout = MAXDWORD; CommTimeouts.ReadTotalTimeoutMultiplier = 0; CommTimeouts.ReadTotalTimeoutConstant = 0; CommTimeouts.WriteTotalTimeoutMultiplier = 10; CommTimeouts.WriteTotalTimeoutConstant = 1000; That worked for the IR-communication, but not for bluetooth. Would be very fine, if someone knows a trick to setup for bluetooth communication !!!

Or has anyone that code-sample?

All I know is that we want to store pictures in a database ( ACCESS), and then retrieve them and show them. I dont know if we could just input them as char*. The embeded nulls in the binary data might be a problem. I really am very new at this, so any help is greatly appreciated!

Re: blob data question Ranjan Banerji7-Aug-02 6:33 Ranjan Banerji 7-Aug-02 6:33  Not sure how to do it using ADO but in principal it should be the same as ODBC. In ODBC the data will come through as a : SQL_C_BINARY | SQLCHAR * | unsigned char * You can load the data into a void pointer and then write it to a file. I did this around 5 years ago. Selected BLOBs of image files from Oracle and wrote it to the drive. Just cannot recall the exact syntax. But essentially you will get the data in some binary form. Check the ADO documentation. It may come through as a BSTR*. Hope this helps. Re: blob data question Giles7-Aug-02 8:24 Giles 7-Aug-02 8:24  Yep, try ADO, open a connection, and recordset, and use AppenChunk, and GetChunk methods for BLOB's . try out this article for a very well implemented class wrappers for all the COM stuff in C++ - http://www.codeproject.com/database/caaadoclass1.asp[^] Giles Help? I'm new. G. White7-Aug-02 5:05 G. White 7-Aug-02 5:05  I've been learning C++ 6.0 and have been doing well. I got a copy of C++.net and there are some things that are confusing me. In 6.0 functions like this are perfectly legal and I have no problems with them: CLine* CDrawingDoc::AddLine(CPoint ptFrom, CPoint ptTo) Whenever I try adding any overloaded function to my project in .Net I get an error message that calls it an "Invalid identifier name." Has anyone got any ideas I could use for this? Do I have to add the functions manually? I really appreciate your time. Thanks Re: Help? I'm new.

Anonymous7-Aug-02 5:32 Anonymous 7-Aug-02 5:32  After using MFC to create an SDI the first thing I do is add a class "CLine" and then 2 member variables m_pfFrom and m_ptTo. I then try adding a function to my class to initialize the from and to points. Return type blank: and a function name of CLine(CPoint ptFrom, CPoint ptTo) I think either I am doing somehting wrong in the wizard or there is a different procedure for this. Like I said, I am quite new to this. In VS6 I have no problems adding functions like this, in .Net I do. I'd really like to start using .Net, so if someone would please advise me on this I would really appreciate it a lot. Thanks Re: Help? I'm new. G. White7-Aug-02 5:33 G.

Just enter the name of the function into the edit box. You enter the arguments into the list separately.
