Hello,
Could you please help me for my following problem.

I am developing a COM Object with VB 6.0 to be used for ASP.

It has a PictureBox Control in a Form Object
Picturebox loads picture from the dynamically created file.
It writes some text on the PictureBox , resizes and saves the picturebox
image to a file. then outputs the picture to the asp page.

It works fine when it is used in a Standard Exe Project. (called as
compiled dll)

also works on debugging mode. (Creates file)

But the problem is it doesn't work when it is called from the ASP.

The Error it gives:
Microsoft VBScript runtime (0x800A01FB)
An exception occurred: 'myObj.ShowImage'
/htdocs/test.asp, line 8

Line 8 is where the Object's method is called

Am I doing something wrong or
is there any restriction to use Picturebox control in COM Object for ASP
if So' can you advice me any alternative solution ?

Thanks in Advance!

Could be a permissions issue. What does the ShowImage code look like?

Hi,
I find out the problem. In fact it is so strange when i assign the
backcolor of the picturebox other than black or white it gives error.
Do you have any idea why it could be ?

Thanks in advance

For the backcolor, are you using a VB constant like vbRed? Or just a number?
If a number, it may not be valid in VB. VB6 doesn't use RGB values quite
the way that HTML does.

Thank you for your attention.
I use VB Colors (Constants) and it works fine when I use same dll in a
Win32 EXE Project.
