Hi again. Currently, I'm using this code within mbOnDownloadInBlinkThread. I execute a few things from Visual Basic 6. When I try to download from the IDE it works fine. However, once I complie the project and try to download from the executable version my application crash. My guessing is that probably another thread is created additionally to the main one. Could you help try to figure out how it is working under the hood?

mbOnDownloadInBlinkThread is vip api, callback on blink(js) thread. You should use wkeOnDownload2

[ronaldcamacho]

'mbOnDownloadInBlinkThread is vip api' On VB6 IDE works properly, how i can implement this in build version, wkeInitializeEx is not stdcall library, show this error bad dll calling convention.

[ronaldcamacho]

if i buy vip can works on compiled app, how much this, send me info please.
