Help about the callback function.

UserSkill

Dear all,

Attached file is my example codes.

Problem: Whenever function LibNameCB() is executed, OutDirCB() function is also called. I would like to avoid this scenario.

Please give me your advice.

 Thanks,

 Dang Quang

  • Dang,

    You'd normally solve this by using some sort of semaphore to indicate that you're in a callback. The reason why the callback gets called is because you're changing the g_OutDir field within the LibNameCB callback - and that (quite rightly) triggers the callback. If you don't want that to happen, you need to code for that. For example I modified your code to store a property on the form called inCallback which allows you to be aware of when you're in a callback. You do need to carefully make sure it doesn't get stuck such that the callbacks never do anything - essentially a state machine problem...

    Regards,

    Andrew.
