Aug 21, 2011Ok what I have is a combo box with a set of default items but i want the user to be able add new items to the combo box's item list. i currently have a text box and a command button for the user to use to add new items to the list with this code attached

so what i would like to know is the correct code to make the additions to the combo box's items list permanent or at least until the user chooses to remove them.
Capture The Enter Key When The Combo Box Has Items In Its List
Aug 25, 2010I have been using the combo Box keypress event to capture the enter key when it is being pressed by the user within the combobox. The combo box style I am using is Drop Down. When there are no items in the combo box list the keypress event will capture the enter key. When I add any items to the list portion of the combo box the keypress event not longer captures the enter key. How do I capture the enter key when the combo box has items in its list.

Building A Form With Just A Combo Box In It That Contains A List Of Other Forms That Made?
Jan 17, 2010I'm building a form with just a combo box in it that contains a list of other forms that I made. I want to program the combo box so that if a user opens it and clicks on "Web Browser", that form with the combo box will close and the web browser that I made will open. Another example is that if a user selects "Media Player" from that combo box, the form with the combo box will close and the media player that I made will open. How would I program the combo box to do this?

Set The Text Of List Items In Windows Forms?
May 28, 2009how to set the value of the text that is displayed for each item of a list control, such as a checkbox list, but really this applies to most list controls, not just the checklistbox control.
I have a checklistbox control,
Friend WithEvents clstTasks As System.Windows.Forms.CheckedListBox
that I usually want to populate with a list of task names. I call the add method to add a Task object to the list. I know that if I override the ToString method, whatever value is returned by that function will be displayed as the text for the list item.
However, in rare situations, I want to display something else other than just the name. For example, perhaps I want to display the name and the value of another property, such as the value of the Boolean property "Optional" shown in parenthesis following the name.
The best that I can think of is to define a property which is set in the GUI layer and then used by the ToString function to determine how it should behave when called. If the controlling property is set to one value, the ToString will return the Name, else it will return the Name followed by the value of the Optional flag. This seems a little disjoint a kludged to me.
The other alternative which seems a little overkill is to define a new class which inherits from Task, for example TaskOptional, which overrides the Tostring method on the base class. In this subclass, the ToString function would return the Name/Optional flag value. However, this, too, seems a little nuts to have to come up with a new class just to modify how the text is being displayed in the presentation layer. I feel that I should be able to control this in the presentation layer without changing the business object or creating a new derived object.
What is the best way to accomplish this?

Forms :: Scroll To Selected Items In Checked List Box?
Apr 29, 2011I've got a Checked List Box full of PC names that the user can check. I've also got a Combo Box that lists the location of the PCs - if the user chooses one of the locations in the Combo Box, it automatically selects all of the PCs in the Checked List Box that are at that location.
However, if that group of PCs are way down the list in the Checked List Box, you can't immediately see that they were checked.I'd like to know if there was a way to have the application automatically scroll/jump down to the area of the Checked List Box containing the PC's that were just checked.
Forms :: DataGridView DataError Exception When Removing Items From Bound List?
Nov 2, 2011I am using a DataGridView bound to a BindingSource which is itself bound to a List of objects. This all works well until I remove objects from the list. If I am scrolled down to the bottom of the DataGridView and then remove a bunch of items from the list it is bound to it generates a DataError exception because the length changed and the rows I am looking at no longer exist... I changed my code to handle that error, but now instead of popping up a message it SLOWLY erases the data in each of the newly invalid rows at the end of the table (I think each time it does one it generates a new DataError, which is why it is so slow).
How do I prevent this? I want to be able to dynamically (and programmatically) add and remove items from the table without the possibility of this error... I assumed this would be handled automatically as part of the data binding process but I guess not.

View 3 RepliesForms :: Make A Program That Reads Text Entered Into A Textbox And Creates A List Of Items By Separating Entries By Commas?
Aug 18, 2010Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string

Determine If Property Is Generic List<of T> Via Reflection And Loop List Items
Oct 1, 2009I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

Shuffling Items Inside A Movie List / Need To Delete Half List
May 16, 2011Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.
