Saving Bitmap as resource programmatically

[Gearoid Murphy]

I am creating a test bitmap (160x120 16 bit depth, BitmapV2) and trying to 
save it as a bitmapRsc resource in a database.  I create the bitmap, 
associate it with a created offscreen window, draw some simple lines. After 
its created BmpGetSizes results in the expected header size of 24 bytes and 
data size of (160x120x2) 38400 bytes.
I thought I could write the bitmap to a resource record using the following 
code:

h = DmNewResource(gImageDbP, bitmapRsc, resId, headerSize+dataSize);
if (h)
{
   recP = MemHandleLock(h);
   if (recP)
   {
       // bmpP = BitmapPtr created by BitmapCreate(160, 120, 16, NULL, 
&error);
       DmWrite(recP, 0, bmpP, headerSize);
       DmWrite(recP, headerSize, BmpGetBits(bmpP),dataSize);
       MemHandleUnlock(h);
   }
   DmReleaseResource(h);
}

However the resource doesnt display as expected and when BmpGetSizes is 
called on the resource bitmap it results in a header size of 16 bytes.  
Anyone know where I've messed up?

Incidentally the aim of all this is to allow the HotSync of such a bitmap 
resource (created using Veo camera on Tungsten) to a bmp file on the host. 
So far I am getting really weird results with certain colours (the lighter 
ones) displaying perfectly but with darker colours coming out as green etc. 
Does anyone know where I could find code to translate the bitmap properly?

Regards,

Ger
