Application update

[Marco Biagioni]

I'm trying to update my program to manage bitmap file written in vb 6.0

For bmp files accessing i used functions like those...
Open NameBmp For Binary As #1
Get #1, 11, pixelOffset
Get #1, 19, w 'Width
Get #1, 23, h 'Height

declaring

dim w as long
dim h as long
dim pixelOffset as long

How can obtain the same in VB.NET?
I tried with

Dim fs As FileStream = File.Open(NomeBmp, _
FileMode.Open, _
FileAccess.Read, _
FileShare.None)

fs.Read(pixelOffset, 11, 7)
fs.Read(h, 19, 4)
fs.Read(w, 23, 4)

but Read method retrieved an array of Byte and doesn't store the read bytes
in a Long variables as Get statement, so i can't do something like

CalculateMultiple4(w * 3)

How can i do?

Hi Marco,

Maybe you should try reading the bitmap directly:

Dim Bmp As Bitmap
Bmp = new Bitmap(NameBmp)

You can then access the width of the bitmap this way:

Bmp.Width

Hope this helps.
