DoesVB6 add some data to an bitmap before saving it to SQL2000?

[geronimi]

On http://www.lierse.be/VB6bitmap.zip is a dat file (from an image
field in SQL2000), it is a bitmap file, in an old VB6 programma that
image is used and visible. So it is valid data. Problem: no code of vb6
of that prog is available.

When I try to convert that data to an Bitmap in C# .NET it fails
because of fucked up data

My question: What is wrong with the bitmap data? does vb6 add some
rubbish to it? I can't load it into image object in C# because a
invalid argument exception (because somethings is wrong in the header
or ...). I tried every offset, and every offset gives the same error.

I'm trying now to rip the pixeldata and put the pixeldata in a own
created bitmapfile with correct header/colormap... But still something
is wrong, the pixeldata contains good data and then a piece of FF 00 FF
00 of the same length and that a few times....

Anybody knows what vb6 does to the imagedata when saving it to SQL2000
? any tips are welcome.......
