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?
i am trying to add subjects and their corresponding grades to a table in you database. the table has these fields: Table1(subjCode,stdID,Grade1,Grade2,Grade3,Grade4,Grade5,Grade5,Grade6,Grade7,Grade8)And i have a checked listbox for the subjects and another for the grades. for each subject, the re are 8 items in the chklistbox, checked. The code should insert into the database a subject and its coresponding 8 grades
but when i try to Save i gives me an exception that index out of range(index was out of the bounds of the array)
I have two lists. One list is a list of names, the other list is a list of how many times each name is found in the first list noted in the database
so... Nick John Jim Jack
is the firs tlist
10 13 13 2
is the second list. Nick had 10, john 13 and so on.I want to sort the second list from large to small, but have the index for the first list still linked to the correct amount of calls.i do it this way so I can
for x = 0 to num_of_names string = lst_name(x) & "-" & lst_count(x) next x
I know how to check whether an item exists in a list using (MyList.Contains), But I do not know how to check the whole list. For example (use one button and one richtextbox):
My application is in VS2008 coded in vb.net.I have a form with a datagridview which loads data from databaase.there is one column where data is stored separated by comma's.Like Name,Surname,LastName name this column as Testing.I have a checklistbox on another of my form.When the user selects a particular row from datagridview another form open and the row selected records are populated in the control of my other form.My issue is i want to check those items of my checkbox that are present in my Testing Column.I have used and array im able to fetch the records just im not able to check the items in my checklistbox that are present in the column Below is my code chkList is my checklistbox controls FORM1 is my form that has datagridview Below is the code of my second form that has checklistbox
Dim classesChecked As String() = FORM1.DATAGRIDVIEW.Item(10,FORM1.DATAGRIDVIEW.CurrentCell.RowIndex).Value.ToString.Split(",") For i As Integer = 0 To classesChecked.Length - 1 ??Logic to check items in checklistbox Next

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 have a checklistbox and I'm running the following
Public Sub ProcessCompanyAssociations() Dim clientID As Integer Dim fullname As String Dim CheckedItems() As String = frmMain.clbCompanies.CheckedItems.Cast(Of String).ToArray Dim UnCheckedItems() As String = frmMain.clbCompanies.Items.Cast(Of String).Except(CheckedItems).ToArray
Is there a way to implement a new column with a header in a checklistbox in vb.net? I've done a bit of searching, but didn't find much on the topic. Should I just abandon the quest and use a listview or some other control?
I would like to make a checklistbox which relates to a database, in that there should be the same amount of Items in the check list box as there are records in the table.
i was going to make a for loop for the amount of records in the database each time adding a new item to the checklistbox but im really not sure how to do that!
Using command As New SqlCommand("SELECT player_name FROM player_table", _ connection) Using reader As SqlDataReader = command.ExecuteReader()
I have a Checklistbox that I want to be able to add content to using a button. The checklistbox by default will always be empty.The content would be from a text file and would a list of email addresses.I would ping each email address to see if it works then select check the working ones and send out my emails but not sure which route to go with to get this thing up and running.Would that be the best way to method to use to open my file for the txt files?
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?
1) i want to make my login page (which talks to a sql table called logins) my first page and it authenticates to that database and doesnt let you in until correct credentials are entered. ? not sure how
2) I have a Checklistbox that is populated with names - ( i want to be able to populate a database called members with those names(Firstname & Surname Only) and from a New members form populate the same members details into the members database this time including address email tel etc etc ....
3) create a delete button that will delete the information from the database and from the checklistbox1 (this is in case the member leaves the club).
4) how do you create trial versions keys etc ...
5) change a progressbar timer to last an 1½ and show hours minutes seconds but once the button is hit to stop the timer it automatically resets to zero.
i have problem here regarding update data when i checked value in checklistbox control.no problem when i want to insert data for the first time, but got problem when i want to update it where the previous data that i checked is still available, plus the latest data i checked. Thats means I got multiple data in my database.
example:
cat lion mouse previous( cat) > i checked cat only
latest in my database, i got (cat,cat, mouse) when i checked mouse and cat.
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 "
When the checked state of a check box change, I would like to know what the new value is.his is what I am doing:Friend WithEvents clstTask As System.Windows.Forms.CheckedListBox
Private Sub clstTask_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles clstTask.ItemCheck Dim SelectedCheckState As CheckState = clstTask.GetItemCheckState(clstTask.SelectedIndex)
Heres some test code I used. Just a checklistbox on the form with this code-behind:
Dim list As New List(Of String) Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load For i = 0 To 10 list.Add("Test " + i.ToString)
[code].....
I use a list to keep track of the items in the listbox, so if I remove one of those items from the listbox I want to also remove it from the list using the same index.If you use this code and load the form and then check all the items, youll notice that when you uncheck one it will remove the item and THEN also uncheck the next item...why is that?

I have a checked listbox which is populated with names(firstname & Surname), I also have a form that has been designed (layoutwise but with no code) to be populated with personal info such as name address,postcode,email address, sql database defined in the program that has a table called members that has the same column headings as the members form.
What i am trying to figure out is how i can commit personal information on my form to that database and copy the firstname and surname from that form to the checklist box if they dont exist? how do i go about this codewise?
