Macros 201 - How To Register Your SolidWorks Macro To Receive Notifications For SolidWorks Events

Why Should I Learn How To Register My Macros To Register For Notifications From SolidWorks?
The common Macros that you see floating around the SolidWorks community are many and most of them are useful. However, most of those Macros run only when explicitly commanded to do so by the user. This is great for most Macros but there are times when it is nice to have some of your code run every time a certain event happens in SolidWorks. For example, what if you want to have SolidWorks filenames determined based on your company’s part-numbering scheme, which is pulled from a database? Wouldn’t it be nice to have the situation where every time SolidWorks prompts you to save a file, the filename box was pre-populated with the next number in the sequence?
You might be thinking, why not just Read more

So here is what you missed out on if you were too lazy to weren’t able to attend the SWUGN Technical Summit - Philadelphia, which was held in King of Prussia, PA (right down the road from the city of brotherly love) :
- A chance to win a free pass to SolidWorks World 2008 in San Diego, CA
- A chance to win a 3D Connexion Motion Controller
- A chance to meet Dennis Miller (Susquehanna Valley SolidWorks User Group Leader) in person

GetObject( ) or CreateObject( )? Is there a difference? - Part III
October 11, 2007
At the end of my last post on this topic, I promised you that I would share a “dirty secret” so I guess I now have to come clean. FYI - “Dirty secret” may have been a bit strong but it sounded cool (at least to me). Anyways, there is a difference between how SolidWorks handles CreateObject( ) and how MS Office products handle CreateObject( ). This is something to be aware of when automating across applications.
What is the difference? In a nutshell, calling CreateObject( ) on an MS Office application interface will always create a new instance of the application and then return a handle to that instance. Calling CreateObject( ) on the SldWorks.Application interface will only create a new instance of SolidWorks if one isn’t already running. This basically ensures that only one instance of SolidWorks at a time is ever automated by your Macro. This is a basic coding pattern called “the Singleton” and it prevents untold suffering and countless tears. SolidWorks is so kind to us and many of us didn’t even know it.
Below are two Macros Read more

GetObject( ) or CreateObject( )? Is there a difference? - Part II
October 8, 2007
Last time I explained how the SolidWorks application object behaves differently depending on whether it is instantiated via CreateObject( ) or GetObject( ). So now you are probably thinking, “That’s it? That was too easy.” Well, I don’t want to be one to disappoint so I will let you in on the rest of the story including a dirty little secret.
So what else is there? The GetObject( ) call has another trick up its sleeve that I didn’t discuss last time. Taking a look at its Intellisense signature provides a clue as to what this is.
In the method signature you actually see two parameters, Read more

GetObject( ) or CreateObject( )? Is there a difference? - Part I

Disclaimer: 99.9% of all the API programming I do these days is in .NET so for the times that I do answer a question incorrectly, 80% of the time it is a VBA (Visual Basic for Applications) question. Since most people start with VBA before they move on to .NET, however, I decided to cover this topic for VBA.
Set swApp = CreateObject(”SldWorks.Application”)
Almost all SolidWorks Macros start out with that same, famous line of code. In fact, whenever you record a Macro in SolidWorks, the SolidWorks Macro Recorder is kind enough to fill that line in for you. What does it really mean, though? And why do a few Macros begin instead with this line of code:
Set swApp = GetObject(,”SldWorks.Application”)
