having trouble only adding the checkboxstatus's that are checked to the gridview.
[code]...
Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck
Try
[Code]....
I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
I am using filesystemwatcher and im watching printer spool activities:
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed
copyfile????
End Sub
But, while printers status is spooling the files and size also changing, how can I copy file bytes by bytes?
Something like this:
Dim a As ByteDim b As ArrayList
Private Sub fsw_Changed(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles fsw.Changed
'+++++++++++++++++++++++++++++++++
get all new bytes and added to arraylist
After the arraylist gathered all bytes, I want to copy back to its original state of files to other location....
+++++++++++++++++++++++++++++++++++++++++++++

I have the following linq statement to go through a dropdown menu's sub items and get what items are checked: vb Dim UnselectedItems = From xItem As ToolStripMenuItem In tsiSelectObjects.DropDownItems Where TypeOf xItem Is ToolStripMenuItem AndAlso CType(xItem, ToolStripMenuItem).Checked = False
I get this error tho: Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'. As you can probably guess i have ToolStripMenuItems and separators in there
However the AndAlso should short circuit in the case where the item is not a ToolStripMenuItem and it doesn't seem to be doing so (as TypeOf xItem Is ToolStripMenuItem=false in this case)?
i want to insert checkbox text only if they are checked.[code]This code will add all checkboxes whether it is checked or not..so that only checked checkboxes would be added in array list

View 8 RepliesThis is bugging (my head is now switched off).I have two array's, one populated with dynamic elements and the other with static values. I am trying to filter out the values that i dont want from one of the arrays:
Dim arrFormItems As New ArrayList
arrFormItems.AddRange(arrSplitValues)
Dim arrItemsRemove As New ArrayList

No matter what i do, i cant filter out the values. Tried the compare method as well..
I have created an ArrayList with items in my Order.aspx.vb. I pass these on to my bllOrder, which passes it on to my dalOrder.

I develop an application in vb.net and mysql server for data storage. I have a problem in my database I have something like 5000 codes stored like code, description, quantity, price, firm. I have a function to extract all the codes from database , it takes about 4,4269 ms to extract all 5000 codes with description and everything... in an arraylist. When I want to put all codes from arraylist in a textbox autocomplete, it took about 2305,400 ms and I think this is a big problem the function to put in textbox autocomplete all the items from arraylist:
Code Snippet:
Public Sub PopuleazaTextBoxDinListaCoduri(ByVal txtbox As TextBox, ByVal list As ArrayList)
txtbox.AutoCompleteMode = AutoCompleteMode.SuggestAppend
txtbox.AutoCompleteSource = AutoCompleteSource.CustomSource
Dim valoare
For Each valoare In list
txtbox.AutoCompleteCustomSource.Add(valoare)
Next
end Sub
This is one item from arraylist extracted from database in this format :
code4993 ->description of code4993(3 buc X 234 lei)
I don't want check if an item with a value exists in the arraylist,I want to know the best code for performance to get how many occurrences of the same item with the same value exists in an arraylist.

I am able to have checked menu items show the variables that I need to show, but they don't uncheck themselves unless I go back and click them. I want to have only one checkmark on a country at a time...is there any way? I've tried if...elseif , but that doesn't work....example below (If I only want Mexico checked and NOT United States, but both are checked still).
If MexicoToolStripMenuItem.CheckState = CheckState.Checked Then
UnitedStatesToolStripMenuItem.CheckState=CheckState.Unchecked...
End IF

I am reading information on missed deadlines from a database. For each missed deadline I add a item to the checked listbox and store the deadline's information in an array. I now want to disiplay all the selected (in the checkedlistbox) deadlines' information in another control, but at the moment I am getting an error. This is the code I am currently using to check which items have been selected
Dim x as integer
For x = o to array.count - 1 do
If checkedlistbox.GetItemChecked(x) = true do
'Here I am displaying array.item(x)'s information in the other control
end if
next
1) Say I have five items in the checked list box and I select all five items, when it gets to x= 3 it gives me the following error "ARGUMENT OUT OF RANGE EXCEPTION was unhandled: InvalidArgument=Value of '3' is not valid for 'index'. Parameter name: index"
2) Say I have five items in the checked list box and I select ONLY the first two items, when it gets to x=4 it gives me the same error as above only for the number 4.
I have tried the methods/functions GetItemCheckedState, SelectedIndices and GetSelected as well, but they all give the same or similar errors. According to me the index cannot be out of range as I have five items in the checkedlistbox as well as the array.
how to use #ZipLib. I've tried there forum and I've looked on this and other sites . I'm still new to VB and trying to teach myself. Using items like a text box are easy but i don't know much about how to use added items such as #ZipLib. Examples of compress and decompress would be wonderful but if you show me what can that would be great too.

View 4 RepliesI have two menu items from which I choose the interface language of a program (English or French).I want either of them to be chosen, both can not be chosen at the same time. I went over the properties of ToolStripMenuItem object and saw three properties that are confusing (Checked, CheckState and CheckOnClick), how can I mix them so that I get that functionality, I mean that when I check the French, the English gets unchecked and vice versa.
View 1 RepliesI'm trying to remove all the checked items in my CheckedListBox. I started by doing
CheckedListBox1.Items.Remove(CheckedListbox1.CheckedItems)
That seemed like it would work, but it didn't. I soon discovered that CheckedListBox1.Items.Remove only works on the the strings of the individual items.
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?
Should: take items and fill checked list box with possible tours that the company can receive (this is done and working) i.e. for 2012, Titleist gets X, Y, and Z; so there are two checked listboxes for 2012: lvl 1 and lvl 2, username specific Both have lists "X, Y, Z" in that order, lvl 1 and 2 is for the permissions level, 1 is lvl 1 and 2 is alex's 0 marking for full details code goes through and checks if lvl 1 is marked, if so it checks the tour in the lvl1 check box if zero is marked, finds the tour in lvl 2 and lvl 1 and checks both items if a tour exists for company but not for the user, the checkbox exists but neither is checked

How do I get the set of checked items in a checkedlistbox when an item is checked or unchecked, given that ItemCheck event occurs before the check state is actually updated? (The SelectedIndexChanged event won't work in my case.)

I can copy checked items from Me.Checkedlistbox into a text box with the following
Dim selectedItems(lstMonths.CheckedItems.Count - 1) As String

For Each item As ListViewItem In ListView1.CheckedItems
lblSelections.Text = item.Text.ToString & ";"

Basicaly I have the option for the user to print a series of reports directly to a printer that is not located in the same area as the application user.
