"Can’t not create activeX component"

Question

Hi everyone, 
 I have a problem as below: 
 I used Microsoft Visual Basic 2010 to make Macro and I used the following to get the end-force: 
 objOpenSTAAD2 = CreateObject("OpenSTAAD.Output.1") When programming I put the reference to file: &ldquo;Interop.OPENSTAADLib.dll&rdquo; 
 The Macro run well for some computers but for some computers specially for Windows 7 there is a massage that: 
 &ldquo;Can&rsquo;t not create activeX component&rdquo; 
 
 Please support us to solve this problem. 
 Regards, 
 Thai

You seem to be using the old OpenSTAAD method which is not part of recent STAAD.Pro installations. It has been replaced by the far more powerful and comprehensive OpenSTAAD Application object. Please refer to the OpenSTAAD documetnation in the Help menu. 
 
Your object should be instantiated using:- 
 
Dim objOpenSTAAD As Object 
'Get the application object 
Set objOpenSTAAD = GetObject( , "StaadPro.OpenSTAAD") 
 
'Get the file folder 
Dim strFileFolder As String 
objOpenSTAAD.GetSTAADFileFolder strFileFolder 
 
Note that in using the new OpenSTAAD Application object, you may need to change some of your OpenSTAAD calls as they now are collated in sub objects such as Geometry or Output functions.
