A Visual Studio 2008 example is provided to demonstrate the use of the SolidWorks API method:

 

   ISldWorks.PostMessageToApplication

 

 

from a C# add-in.

 

For illustration purposes the ModifyNotify event handler for Part and Assembly document is used.
In general little work can be done in the ModifyNotify event handler, as SolidWorks is typically still in the process of making a modification, and the model may not be in a consistent state yet. Hence a message is posted, which is processed later.

Here "later" is determined by which other messages are in the Windows message queue.

 

The example illustrates the use of a callback data helper class "AddinCallbackData", which makes it easier to get data across from the post site to the processing site.

 

Other methods involved:

 

ISldWorks.AddCallback
ISldWorks.RemoveCallback

 

 

Minimum SolidWorks version:

 

- for 32-bit  SolidWorks 2010

- for 64-bit  SolidWorks 2011  to be able to use ISldWorks.PostMessageToApplicationx64

 

 

Add references to the following Interop Assemblies:

 

SolidWorks.Interop.sldworks.dll
SolidWorks.Interop.swcommands.dll
SolidWorks.Interop.swconst.dll
SolidWorks.Interop.swpublished.dll
SolidWorksTools.dll

 

for your version of SolidWorks.


A helper class "Win32" is added to be able to determine on what kind of OS SolidWorks is running:

 

  32-bit
  32-bit WOW64 on 64-bit
  64-bit


This class uses P/Invoke.
