CoInitialize_ & MessageRequester

[Phantomas]

Hello. Some Issue with CoInitialize_ API function and MessageRequester.

In this code CoInitialize_ return 0 (zero):

Code: Select all

MessageBox_(0, "", "", 0)
Debug CoInitialize_(0)

Here CoInitialize_ return 1:

Code: Select all

MessageRequester("", "")
Debug CoInitialize_(0)

What's wrong with MessageRequester?

What's wrong with MessageRequester?

I think PB calls Coinitialize() somewhere for some reason.

When displaying a requester in general it seems:

Code: Select all

InputRequester("", "", "")
Debug CoInitialize_(0)

Code: Select all

ColorRequester()
Debug CoInitialize_(0)

Code: Select all

FontRequester("Arial", 10, #PB_FontRequester_Effects)
Debug CoInitialize_(0)

etc.

This is more a side-effect than a bug IMO, like this one -> http://www.purebasic.fr/english/viewtop ... =4&t=61239

Subsequent calls to CoInitialize or CoInitializeEx on the same thread will succeed, as long as they do not attempt to change the concurrency model, but will return S_FALSE

That's probably why you get 1 (#S_FALSE) in your second snippet.

There is nothing wrong, PB commands can call any API internally for its own purpose. MessageRequester() isn't just a wrapper to MessageBox_() and handle also all program window locking.
