hi , my name is saleem

can you answer my qestions please

1- i made a simple media player to play sound and video i just want to know how can i get all file names

i selected and pressed enter

i tried a startupnextinstance event

and i got all file names but this was a very slow way and doesn't work well when you have alot of files (more than 100)

i think i should use somthing exist in windows

i think somthing related to user32.dll or another file

please can you tell me what the way is

( i want the same way that is used in windows media player to open many files)

2-i can drag and drop files from explorer to my play list using dragdrop event but this doesn't work when i drag files from openfiledialog to my playlist

my listbox doesn't feel dragdrop event

I'd like to see much more in this area since it has a lot of promise. Some ideas:to show as different sample programs:

- A sequential workflow with 4 states executed sequentially

- A workflow with 2 sequential initiialization states floowed by a loop containing 3 state, followed by 2 states for application shutdown

- A simple workflow showing how to do a case statement with 4 different cases using if/then/else, if then else...

- How to handle errors (i.e, how to setup a global error handler state that cleans up an application from any unhandled error in any one of the states in the application).

That list is sounding like a workflow patterns how to list of topics......

I've done a couple simple workflows but the workflow designer user interface was difficult to use .

Hi Beth,

I've actually just started learning workflow this past week and, low and behold, you blogged on it!

I'm really liking workflow so far but have a question for you--Why is the developer experience with workflow so non-VB? For example, a code activity's event handler doesn't use the Handles key word. I can manually edit the designer file and declare the code activities with the WithEvents key word and add the Handles clause to the event handlers then remove the AddHandler statement. But it is too much work. There are other nuances that just don't feel right.

Win forms and Web forms both have a consistent VB feel but workflow doesn't.

Please blog about or enhance the MSDN documentation topics for workflow as there has been a slow trickle of new articles in recent months. The videos are helpful but written articles are more useful in the long run as they can be promoted to MSDN topics, .NET framework reference examples, etc...
