Initial API call fails

Unread post by bellmik » Tue Sep 03, 2019 3:12 pm

Hi TopSolid,

First real post here.

I am using the API to programatically create a consistently formatted .top file that matches our sales order. Our engineers will then use this .top file to add their materials and draw from.

Not having a great start as the code is failing after on my initial API call.

My code is below. The initial popup I get after a few seconds is:

Standalone licenses

Cannot locate protection key.
Check the key connection and driver installation.

Software will run in demonstration mode.

I am using a shared license, and I can load and run TopSolid from my desktop without issues. Do I need a standalone license to use the API?

After a few more seconds I get the error message located at the bottom of this message.

Here is my code (written in C#, I can provide the VB.NET equivalent if need be.)

private TopSolid.Application TopApp;
TopApp = new TopSolid.Application();
ITopDocument topDocument = TopApp.Documents.Add("Test");
ITopDocument doc = topDocument;

It errors out on the line:

TopApp = new TopSolid.Application();

with the message

Message=Retrieving the COM class factory for component with CLSID {96DAB3E1-B2C2-4F2A-A175-91AA0275A714} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

Well after a month of frustration, I finally found out what to do. There is a top.cod file that must contain the module parameters that you need to use up a license for.

It should mirror the parameters that are part of your desktop shortcut.

In our case it was:
