When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?

Someone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available.

I have an ArgumentException was unhandled message: Cannot add or insert the item '1' in more than one place. You must first remove it from its current location or close it. Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

View 9 RepliesI'm trying to finish up Visual Basic project for a class to create a playlist of files and to have them played.I have everything working if I single click the item from my list, and then click the play button in the WMP control portion of my form.I then want to add the functionality of double clicking the selection in the list and play with the following code:
[code]...
and nothing seems to happen.Digging into values of the debugger at the time I try to play the file:
[code]...
The sourceURL of the first item in the playlist is correct, but the duration is 0:00 (it should be 0:01). Since it seems there is no duration detected, nothing is played. Any idea what I missed? Again, if I single click the file, which sets the playlist as I want, then click PLAY on the GUI controls, it works fine.Also, is there any way for the program to detect when the song has changed when playing a playlist of multiple songs? I want to have label fields showing "Now Playing" information that would change info as the songs change, and maybe even change the item selected as things are played. I've not yet found a way to detect this change, only when the player starts and stops in general.

View 7 RepliesI have a VB 2008 connected to my localhost SQL using DataGridview, BindingSource and DataTable. All works fine, i can add, edit and delete the row and the SQL database is also affected.
However, there is one thing that bugs me, that is sorting.
Problem My table in this database is still quite empty, it only has 6 rows
However, if I spam-click the column header, the sorting seems taking some time to sort, so that, the sorting result does not follow my mouse spam-clickings
Note: Spam Click = Clicking the mouse button in high frequency, something like click click click click click click click click click, etc
