    Posted: 08 March 2011 at 5:44am
In a large application it is pretty hard to associate a unique "command id" with any bitmaps added to the global XTPImageManager() instance.

I noticed that the CXTPMarkupContext  has a local image manager instance (m_pImageManager) declared public. This instance is apparently never initialized (no methods found). But the markup image class checks this instance first before checking the global image manager.

I hence new the m_pImageManager in my code when I want to work with "local" bitmaps only valid in this markup context. The markup context releases the m_pImageManager automatically in the destructor.

Is this SAFE to use or does Codejock plan to remove this variable in a future update. As usual none of this is documented and I don't want to rely on guesswork.

Perhaps you can make this more official by adding a proper method to CXTPMarkupContext to create its own image manager...

Hello,

yes, its safe, but you assign new CXTPImageManager created duynamically

->m_pImageManager = new CXTPImageManager();

Hi Oleg,

Why he can not use the global ImageManager ?
->m_pImageManager = XTPImageManager();
->m_pImageManager->InternalAddRef();

Hi, Oleg

yes, as I wrote, I "new" the instance in my code. But I just wanted to make sure that you don't drop the variable in a future release. This is all undocumented (as too often) and there are no methods to initialize the member properly.

Using the global image manager is not always an option, especially since every bitmap needs a globally unique id. Using the local image manager avoids polluting the global image manager.

This would not help because I actually don't want to use the global image manager because I don't want to pollute the image manager identifier space.

Thanks.

I see. I checked the release notes but there was no mention of any change.

I do not install every XTP update for deployment reasons so I could no t search the source codes for changes you may have made or not.
