I can't load a GdPicture ActiveX control within Visual Studio .NET or Visual Basic 6. "Error loading library dll."
The control you are trying to use is probably marked as safe for scripting and safe for initializing.
If you encounter problems loading it, you should copy the objsafe.tlb file into the system32 directory.

How do I unlock my GdPicture component?
For all GdPicture Toolkits, the final version is the same as the evaluation version.
You just need to unlock all the used objects using a commercial or an evaluation license KEY, using the SetLicenseNumber() method.
-> IE: object.SetLicenseNumber ("0012345678910111213141516")
Note: You should call this method before any other methods of the used object. Also, don't forget to call this method for all used objects!
You can purchase a license key here.
You can get a one month evaluation key here.

What kind of color value do I need to use as a parameter with the drawing methods RGB or ARGB [for ActiveX editions only]?
GdPicture components work only with the long ARGB color value. This is available for 1bpp, 4pbb, 16bpp, 24bpp, 32bpp... bitmaps.
To get a long ARGB color value, you can use the ARGB() method.
The ARGB() method returns an ARGB long color value by using specified values for the alpha, red, green, and blue components.
Ex:
-To get the red color value:
nRedValue = object.ARGB(255, 255, 0, 0)
-To get the semi-transparent blue color value:
nSemiTransparentBlueValue = object.ARGB(127, 0, 0,255)
How do I display PDF files in the GdViewer control?

Unless you have disabled User Access Control (UAC), all user accounts except Administrator need to have elevated administrative user rights.
