MMF - Problems to Report

[droberson]

1. When using the action Timer - User has been away from computer ... there is a problem with the following.

On a frame add a Direct Show object and some other object like a edit box. Add code to use Directshow to play a video clip when the frame starts. Add code to have the edit box disappear after 5 seconds witn "Timer - User is away from computer..."

Notice that if the mouse in "not" over the Direct Show everything works fine. The video plays and in five seconds of not typing OR moving the mouse the edit box disappears as define.

Try the test again but this time move the mouse in circles over the Direct Show object while the video is playing. Notice that like before the edit box disappears - but it should not given how the Timer action "User is away from computer" is defined.

MMF should see the mouse moving (clearly the user is at the computer) and not cause the edit box to disappear. It appears the cursor movement is ignored and the action does not work correctly.

2. There appears to be a problem with trying to use the scrollbar actions and condition of the following:

Condition - Scrollbar (On Scroll)
Action - Set position of scrollbar
action - Set postion of video clip.

Here I was trying to use the scrollbar to move forward in a video clip as it was playing. So I set the range of the scrollbar from 0 to duration of the video clip in millseconds. I then play the video in a Direct Show object and using the scrollbar wish to move forward. I should be able to check the position of the scrollbar and set the position of the videoclip. So if I move half way on the scrollbar I should see the video clip advance half way also. However MMF Runtime would abort and lock up. I had to do a use the task manager to stop the runtime. This happened several times.

I have had problems with the Directshow Object before, not registering certain mouse events while over the object. I think this is a bug with the Directshow Object.

I have been doing more testing and the scrollbar object seems to be the problem. During the running of the video I cannot tell it to set the postion of the scrollbar to the position of the video. It hangs up the application. But I know I had this working on another application I did.

Maybe wait until the scroll bar is set before trying to set the position. Because the moving is too fast and probably is what crashes the application

What is the range for the EasyScrollbar object? For example is the range 0 to 1000, 0 to 1000000000 ?????

[droberson]

I did find that the setting the range high does cause problems with the proper functioning of the scrollbar. This appears to be an error with the easyscrollbar.

The range's limit might be 65535 or 32767.

[droberson]

Yes I agree. The EasyScrollbar range needs to be enlarged due to the fact that it can be used with video clips that set duration range in terms of millions of milliseconds for example.
