Using a DC instead of Picture1.Picture

[Electroman]

I've used the code below to fill "bmp" with the details about the picture in "Picture1".

Private Type BITMAP
    bmType As Long
    bmWidth As Long
    bmHeight As Long
    bmWidthBytes As Long
    bmPlanes As Integer
    bmBitsPixel As Integer
    bmBits As Long
End Type
Private bmp As BITMAP
 
GetObjectA Picture1.Picture, Len(bmp), bmp

The problem is i'm no longer wanting to use a PicBox and have stored a picture in a DC I created instead. Does anyone know if there is a way to get these details from just the DC, The only part of "bmp" that I really need is "bmp.bmBits".

Thanx to anyone that can help.

I am just learning VB and bitmaps but the way I do what you're trying to do is:

Dim bmBits As Byte
 
f = FreeFile
Open strFile For Binary As #f
    Get #f, 29, bmBits
Close #f

I've sort of solved the problem but it seems as if there should be a better way to do this. Anyway this is how i'v managed it:

Private Type OffScreenDC
    DC As Long
    Object As IPictureDisp
End Type
Private MyPict as OffScreenDC

I used this to create the DC:

'Create compatible DC
MyPict.DC = CreateCompatibleDC(frmMain.hdc)
 
'Load bitmap
Set MyPict.Object = LoadPicture(iFilename)
SelectObject MyPict.DC, MyPict.Object
nFirst = True

Then I used the "MyPict.Object" instead of the Picture1.Picture:

GetObjectAPI MyPict.Object, Len(bmp), bmp

Only thing is now I need to keep the IPictureDisp type when before I was getting rid of it once i had loaded the picture, so my question now is does anyone know if I can regain the IPictureDisp type for a DC when I need it because I might not always use a file to fill a DC.

Thanx sequoyan, I'll look into that as well, but the thing is i'm trying to work with a loaded Bitmap and bmp.bmBits points to where in the memory the data is(I think).

Sure, anytime. I'm just starting to learn DCs so what you're trying to do is a little beyond me.

But if it helps at all, and if you didn't already know it, byte 29 is the bit depth.
