Maybe 64-bit dll.

[Davider]

iGrid is a 32-bit OCX,

Hints are found in the description below

The typelibrary contains error in coclass iGrid definition. When enumerating its interfaces, cannot get one of interfaces. I tried a workaround (ignore the interface), unsuccessfully. I also tried to load the typelibrary with oleview.exe from Windows SDK, but it cannot display iGrid coclass too (same error).

You can report it to 10tec, maybe they will fix it.

Anyway, the COM component is too complex to use in QM. Would be a nightmare to use it in QM. Or I'm now spoiled by C#.

Thanks for your help.
I found the following description in the help file, which is really troublesome

To use an ActiveX control in Delphi, you need to deal with its type library and transform VB syntax using the COM control interface. Moreover, COM data types (such as Variant) are not native to Delphi and you will get additional problems with them if you want to use iGrid in Delphi. Delphi programmers also say that VB is the ideal development environment for iGrid.

Execute successfully with the following code

from:
iGrid750_10Tec.iGrid ig3
to:
iGrid750_10Tec._iGrid ig3

Now there's a new problem.
The object member list contains only properties and methods without events

The following error message is displayed after the following code is added

ig3._setevents("sub.ig3")
