Nov 5, 2010Assuming I have a folder structure like:
[Code]...
This works fine, unless I have Windows Explorer open and I'm looking at the 'MySubFolder' directory.

Any thoughts on how I can get this to perform correctly (i.e. delete), even when running this code while having the folder struture open in Windows Explorer?

VS 2008 Why Doesn't The ComboBox Have A Selected Integer Property
Nov 26, 2009Why can't you set the selected integer for the items in the combobox in the properties window instead of adding code in the form load event? I don't like to have to do things that way, I feel like it is less efficient. Should I just deal with their being no value property for combo boxes or is there a way to do it easier?
View 3 RepliesBasic Search Doesn't Compare Selected Element With Textbox Value
Sep 17, 2011I've been having problems with a really basic search routine that I have used successfully before but now for some reason does not. I have a text file that looks like this: Spindly Killer Fish, fish, spindly, aggressive, dangerous, grey, Sect.B Tank.1, 20 It is then loaded into a two dimensional array with comma separation. This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]
View 2 RepliesCombo Box On A Tab Control SelectedIndexChanged Event Doesn't Fire Until Tab Is Selected?
Jan 24, 2012I am using VS2008, vb.net, Windows forms project.I have a combo box control on a tab control.The selected value of the combo box is bound to a binding source.The data source of the binding source is a typed dataset.I set the datasource of the binding source when a record is chosen in a data grid control.Since the combo box is bound to the binding source, this should set the selected value of the combo box, and fire the initial SelectedIndexChanged event.Therefore, I remove the SelectedIndexChanged event handler for the combo box before I set the datasource of the binding source, and add the handler again after the datasource is set.

Delete The Selected Name From The List?
Nov 6, 2010I've been working on a program lately. On the form load it loads a list box with a list of names from a .txt file. It's a sign in form, so when people click their name then the button it will write to a .txt file their arrival time, and the folder is their name. I can make it do it one at a time, but that's so inconvenient. I have the list box set so it accepts multiple selections, but I need to make it write the time for everyone.
how to delete the selected name from the list that would be extremely helpful, that way the person isn't signed in multiple times.
