Hi Frank,

Question: Which functions of ISldWorks should I use to catch the error of security device or the status of SW locked when the relative USB dongle is removed?

For customer or user, when the relative USB dongle is removed, SW only pushes an error dialog of security device and is locked. Then, SW is closed when user click OK button in the error dialog.

However, for API developer, ISldWorks still has original value when the relative USB dongle is removed. I need catch the error of security device (before SW is closed), do other things (For example, SW_DCT converter will replace   SW_DCI converter).

First of all, I introduce my development information (data exchange between SW and PC-DIMS) about PC-DIMS software which is measurement software for geometrical product.

In PC-DIMS software, there are SW_DCI (directly read SW data or information into PC-DIMS through SW_API as well SW is installed) and SW_DCT (SW format file convert PC-DIMS format file as well SW is not installed) interfaces. I’m in charge of SW_DCI. When SW_DCI begin to work or convert, I need catch the status of SW_dongle. My goal is that SW_DCI will be changed to SW_DCT, if SW is disabled.

Best wishes,
yogy

Hello,

Earlier I wrote:

If your SW_DCI application is a COM-based add-in, the:

    ISwAddin:isconnectFromSW

method will be the right place to notify your PC-DIMS software that SolidWorks is no longer available.

This method will be called when SolidWorks unloads an add-in.

Another solution that comes to mind is using Win32 API functions to obtain the process handle for sldworks.exe and use WaitForSingleObject to wait in a separate thread for the SolidWorks process to terminate. However, this is outside the scope of the SolidWorks API.
