Addon not loading in zero document state

prakash.muthu — Wed, 30 Aug 2023 07:39:23 GMT

Hi,

The .arx file not loading in startup when application started with zero document state. The same addon getting loaded on opening document. Is this AutoCAD behavior or any solution available.

Thank you.

In kInitAppMsg message you cannot use document as far as AcApDocManager::curDocument() == 0 and acdbHostApplicationServices()->workingDatabase() == 0 in zero document state.

The intension is not to use document in kInitAppMsg. Just to load addon arx and linked dll's in application startup.

Still didn't get any solution for this problem. Is it AutoCAD restriction to load arx only when document in open. How about listening to app events without opening document.

You use acedRegisterOnIdleWinMsg in kInitAppMsg, do initialization,

then acedRemoveOnIdleWinMsg inside of AcedOnIdleMsgFn if it’s not needed

kInitAppMsg not getting called when application starts with startup 2 and start mode 0. Its getting called on creating new document or opening disk file.

I thought it's always called, how would you call acrxLockApplication, or acrxBuildClassHierarchy() and other functions?

Not using mentioned methods.

Pretty sure kInitAppMsg is always called, you’re just not seeing it. Try making a sample with this code

Thanks @daniel_cadext for the code sample.
We also using similar code. The problem is not with kInitAppMsg. The arx file bundled in packagecontents not getting loaded when opening AutoCAD with startup 2. Same code getting called as mentioned in sample after opening a document. Maybe AutoCAD behavior to load addons when document in open.
