CheckListBox Filled With Items From Array
Oct 18, 2009
I have a CheckListBoxthat is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a CheckListBoxthat before so I'm not really sure how to go about this. Here is what I have tried so far:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
Dim TempNameList As New ArrayList
If cmbRemove.SelectedIndex = 0 Then
TempNameList.AddRange(NameList)
Array.Clear(NameList, 0, NameList.Length)
When I re-display the array into the CheckListBoxthat it shows that nothing was removed from the array.

I've searched the forums and have only found similar things for ASP but not this exact function in VB.
I've got a checklistbox in my program which has 8 choices. I'd like to append the selected indices (the text not the index number) to a textbox on my form. How would I do this?

I made a quick search but couldn't find any help I need to put the values of a checklist box into an array. I've found several solutions on the internet but all of these don't seem to work for integer arrays. This is what I've got so far
" Dim RemoveValues(checklistRemoveBrew.CheckedItems.Count - 1) As Integer
Dim C As Integer
For C = 0 To checklistRemoveBrew.CheckedItems.Count - 1
RemoveValues(C) = checklistRemoveBrew.CheckedItems(C)
Next "

I made a web application were you can check if somebody paid for their e-ticket and if so once you push the send mail button the person will receive his/her E-ticket with all the information regarding the activities they ordered.
I just have one problem the mail that I send collects data from a data grid and puts that in a static array.
Dim testarray(20, 1) As String
And of course the code to get the data from the data grid into the array
A part of the html code to send the e-mail is as following
"<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(0, 1) & "</span>" & "Activity: " & "<span style=""font-size:14pt;"">" & testarray(0, 0) & "</span>" & "." & "<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(1, 1) & "</span>" etc.
The Testarray(0, 1) and up are filled with the corresponding amount of tickets and for which activity. As you can understand if for example Testarray(1, 0) and Testarray (1, 1) do not exists because there is no corresponding ticket amount and activity in the grid. But Testarray(0, 0) and Testarray(0, 1) do exists, the person will still receive a empty line in his/her mail
Tickets: 5 : Activity: Sleeping
Tickets: Activity:
I know that with a dynamic array maybe I could fix that problem, I was wondering if there is a work around so I can check if a Testarray is empty or not and then only when its filled with data it will write the line into the e-mail.

I have a RadioButtonList control which triggers a Sub LegalGaps on SelectedItemChanged event. This Sub creates and fills in an array the size of which depends on the User's choice of radiobutton options. The second Sub AvailableDays shall be able to read that array and highlight the days in the Calendar control accordingly on DayRender event. May I somehow declare an internally created variable a public one?

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I have 3 CheckListBoxes, and I want to save all of their "checked" states. I tried to change the code to save and load one to work for three, and this is what I came up with:
vb
Private Sub savechxlst()
Dim FileStream As New System.IO.FileStream("C:CheckedListBoxData.cld", IO.FileMode.Create)
[Code]....
Unfortunately, all this does is combine all of the checkboxes into one list (ChxLstSym), and leave the other lists (ChxLstAud and ChxLstEx) completely blank. By this I mean ChxLstSym ends up having 15 checkboxes instead of each of the 3 Lists having 5 checkboxes (Which is how it was before I saved and Loaded), though it does remember which boxes were checked originally.
Is there a way to fix this so that I can save and load the checked states for all three of the checklistboxes (ChxLstSym, ChxLstAud, and ChxLstEx) so that they are all in their own lists upon loading them?
