depends on the database server you're using. for instance, interbase and it's open source derivative, firebird, have a "blob" type [Binary Large OBject] which can save almost anything. mysql and postgresql have that too. ms sql server has an "image" type. exactly how you go about storing them and retrieving them is dependant on the database server. that's where you need to read up a bit... hth! -- Raoul Snyman Saturn Laboratories e-mail: raoul.snyman@saturnlaboratories.co.za web: http://www.saturnlaboratories.co.za/ blog: http://blog.saturnlaboratories.co.za/ linux user: #333298

hi, i have tried this method but what happens is that after compiling when we run the application instead of the bitmap there is a blank button or a white button.PLease check it n tell me. vibhu

Well, presumably, you're sending NOTE ON/NOTE OFF messages at the moment. 1001nnnn 0kkkkkkk Note On event. 0vvvvvvv 1000nnnn 0kkkkkkk Note Off event. 0vvvvvvv where nnnn is 0-15, being the MIDI channel number. You should be able to change to a different patch by sending 1100nnnn 0ppppppp ppppppp is your patch number, less one; where 1 = Acoustic Piano, 15 is Tubular Bells, 22 is Accordion. Check out this[^]for a list of patches, assuming your MIDI target device is GM compatible. You don't say how you're sending the messages; If you're using midiOutShortMsg, then you need something like: 0x0000CnPP as the data to send, where n is your channel, and PP is your patch (0..126 or 0-7E in hex) Hope that helps.

The simplest way to play an audio file on windows is to use the PlaySound function. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/\_win32\_playsound.asp Putting a bitmap on a button? Depends on whether you're using mfc, wtl, win32 api, .net or something else. There's probably a dozen tutorials on this site alone explaining it, though.

If you are thinking winmm.dll, you do not directly link DLLs to a project, you link the import library for them with the project. Try adding winmm.lib to your list of Libraries to link with.

Ross, How would you go about attaching 'winnm.dll' to a project? I am at a complete block at the moment which isn't good, I am just unable to get my head around linking the dll files then accessing them. Do i need to create a header file? Which things will i then need to include in the file? Cheers Mav :omg:
