When I run this code in VB.NET, it hangs on the GeneratePerlinT exture call.
I think it is because I am not calling it correctly.
The C# code that works:
[DllImport("Perl inDLL.dll")]
static extern unsafe void GeneratePerlinT exture(void *ARGB32_pixels, int w,
int h);
....later...
BitmapData bmData;
Rectangle rect = new Rectangle(0,0,b mp_ARGB32.Width ,bmp_ARGB32.Hei ght);
bmData = bmp_ARGB32.Lock Bits(rect, ImageLockMode.R eadWrite,
PixelFormat.For mat32bppArgb);
GeneratePerlinT exture(bmData.S can0.ToPointer( ), bmp_ARGB32.Widt h,
bmp_ARGB32.Heig ht);
bmp_ARGB32.Unlo ckBits(bmData);
What I've done in VB.NET:
Declare Sub GeneratePerlinT exture Lib "Perlindll. dll" Alias
"GeneratePerlin Texture" (ByVal ARGB32_pixels As System.IntPtr, ByVal x As
Integer, ByVal y As Integer)
....later...
Dim bmData As Drawing.Imaging .BitmapData
Dim rect = New Rectangle(0, 0, my_bitmap.Width , my_bitmap.Heigh t)
bmData = my_bitmap.LockB its(rect, Imaging.ImageLo ckMode.ReadWrit e,
Imaging.PixelFo rmat.Format32bp pArgb)
GeneratePerlinT exture(bmData.S can0, my_bitmap.Width , my_bitmap.Heigh t)
'Hangs here
my_bitmap.Unloc kBits(bmData)
I have the source code for the DLL if needed.
I cannot figure it out!
Thank you if you can help.

I've tried some converters, they do not work. Some just spit out the same
c# code with no explanation.
Thank you!

I would just make sure that you values being passed to the
GeneratePerlinT exture are correct.
ie Make sure that my_bitmap.Width contains the actual width of the rect.

just a stab here, but the c# code has an unsafe void - i didnt think that
vb.net supported unsafe code. might that be the problem?
aware of my ignorance,
