You must write an owner drwan menu.
You can find samples in codeproject.

Pause and resume using asynchronous monikers.

25-Oct-07 4:02

I think somebody dont want that see mine on the codeproject so he/she gives 1 vote to me and also he/she afraids of speak with me.
But I thankful of you for your vote :-Dif you remember some times ago somebody give me 1 vote and you told why you got 1 vote,remember?

Hi everyone,

I have used CAsyncMonikerFile for loading files asynchronously from a URL.Problem is with resume operation.I'm unable to resume the download, instead the download is starting from beginning.Below is the code I have used for Pause and resume operations

Pause:
m_asyncMon.Close();

Resume:
m_asyncMon.Open(url);

where m_asyncMon is the variable of my CAsyncMonikerFile.

Please let me know if there is any other way to pause and resume download using asynchronous monikers.

Thanks in advance..

I know nothing about the monikers -- but if you resume and you get a fresh stream from the server, maybe the server didn't understand that it was a pause?

You can tell me to go away....

As far as my knowledge is concerned when a url is requested the content is first downloaded to cache and then to the browser. So when part of the download is completed then paused and later on when its resumed I don't expect the cache to be reloaded instead I want it to be have a continuation so that it can be resumed from the previous location.

Anyways I'm not sure about the process of streaming from the server.

Thanks,

Splash screen stays more than programmed timer value

Hi,
I have developed a multithread application, which will communicate with an embedded system. At startup the application should display splash screen for 5 seconds and display the application window. The problem is the display period of splash screen is more than one minute. When I monitored the messages using SPY tool I could see, other messages kept posting to the application window, whereas splash timer message got posted last.

Can anyone tell me why it is happening and how to get rid of the problem?

From MSDN: The WM_TIMER message is a low-priority message. The GetMessage and PeekMessage functions post this message only when no other higher-priority messages are in the thread's message queue.
