Ive got a CheckedListBox with 20 rows in it, each with checkbox's which are checked or not-checked. What I want to do is to check each checkbox, row by row to see if it is checked, and then to store this is a listofintegers (1 if its checked, and 0 if its not).So the output listofintegers should be something like "01011000010100010011".

Okay I am now using a CheckedListBox and I was wondering if there is a way to save the checkstate of the items? Its very easy with checkboxes but I have not found out how to do it with this.
View 5 RepliesHow can i make ONLY one selection possible from the checkedlistbox at a time? If i have already selected one and if i select another item the previous item should be deselected.
View 1 RepliesIn an application I build a list of CheckedListBox and display it to the user. I want to make the selection exclusive to only one. I noticed that you can check more that one item in the CheckedListBox. How can I stop that and as the user check the second box I uncheck his/her first selection.
SForm.ChkBoxPts.Items.Add("Paarsa")
SForm.ChkBoxPts.Items.Add("Jeff")
I.e. If I display the above two items or may be even more, I would like to force the user only select one and only one.
I know that sounds strange but I came across this website today that uses this ability and I've been going nuts trying to figure out how they do it.
The website is [URL]
Also here is a screenshot of the options I am speaking of
There is a combolistbox that has a list of topics.
Depending on what topic you choose will determine what checklistbox option will appear in the check list box.
What are they doing there to create that option? I was thinking that maybe they created 20 checkedlistboxes and then if the selection of the combolistbox is "THIS" then they set the getfocus to that checkedlistbox but that didn't quite work for me.
With this project i had to link a MySQL database and then let it add every item in the table as a new checkboxitem, and that is working perfect, but now i need to get the check state of each of these items with an if statement because these need to act like a filter.i tried a couple of times but i just cant get the result i need.

When i check the box, it enables all controls, if i uncheck it, nothing happens.
I understand that Checked is a boolean, which is not the case of CheckState.I understand that CheckState also have a undeterminate possible value.But I don't understand why we have them both. I think that CheckState would be sufficient. What is the need for Checked ?

The code reads ever column text perfectly but does not read the checkstate of the checkbox.Because the checkbox has no text to it.I was thinking of giving each checkbox a tag and on the click event change tag from True to False depending on checkstate. Is that a good idea or is there a faster way around this?

View 1 RepliesI have a checkbox on my form chkActive, I want to deal with it in 3 cases. [Code] I don't have a problem with building the query, my problem is with clicking on the checkbox by clicking on the checkbox by mouse, I can only get Checked and Unchecked, I tried to use the right mouse button click, it did not fired (or I did not test deep enough) I know I can put a button to change the checkbox value to Indeterminate but that will be ugly. I can replace checkbox with combo, which is what i am thinking of doing but I just wonder: Cannot I set the checkbox state to Indeterminate by mouse any how?
View 2 RepliesI'm trying to reset a form after a game has been played. I used checkboxes to indicate when the user picked a particular line item to update and then flagged the checkbox as checked and disabled.Once all the checkboxes have been checked, the game is over and I want to show a dialog (msgbox) that will allow the user to start a new game or exit the app. To reset the form, I was changing all the checkstates back to unchecked (along with resetting other variables), but the checkchanged events are being triggered and I end up in a loop.Is there a way to change the checkstate without triggering the event?[code]....
View 2 RepliesI am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code:
[Code]...
The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB.The following code partially works until the "Select All" checkbox is clicked at which point if other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected.
Trying to get a database into my Checkedlistbox. This is the code I have so far: Private Sub CheckDevices_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim connectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=N:DeviceList.accdb"
Dim str_DeviceList_Select As String = "SELECT * FROM DeviceList"
Dim myConnection As OleDbConnection
Dim myCommand As OleDbCommand
Dim myAdapter As OleDbDataAdapter
Dim myDataSet As DataSet
[Code]...
So I have the dataset with database in it, but I am struggling to get it from the dataset into the Checkedlistbox. Could someone do some quick code for this?Secondaly, I also want to set the checkbox's by using a string of integers which will look like "0110100110". If the value is a 1, I will want the corresponding checkbox to be checked, eg, "0110100110" So I would take that one, and check the 8th checkbox down in the checkedlistbox... So if anyone if feeling really generous, could use a little help with this as well.
I have a CheckedListBox that will be used to choose what columns they want to select from a database. Is it at all possible to display it in the format of [Table Name].[Column Name]?So far I have this:
con.Open()
theQuery.Connection = con
theQuery.CommandText = strColumns
theAdapter.SelectCommand = theQuery
[code]....
I tried adding another clbFields.DisplayMember, but this obviously just overwrites the table name with the column name. I also tried doing:
clbFields.DisplayMember = "Table_Name" & "." & "Column_Name"
but that didn't work either.I know it's not exactly life threatening if the user can only see the column name, but it'd be nice to be able to see the table name in case of any duplications?

I have a few checkedlistboxes in my GUI and the items in them are changed as needed. For example if I check an item in checkedlistbox1, it would trigger the items fromcheckedlistbox2 to be removed and new items will be added to it that are relevant.Similarly, depending on when the items are checked inside the checkedlistbox2, it will trigger new items to be added to checkedlistbox3. So I have added the functionsSelectedIndexChange to handle when items are checked inside the boxes.
I am running into a problem however. For example, I have some items in the checkedlistbox2 and one of them is already checked. When I click on something else in checkedlistbox1 it clears out all the items and repopulates the checkedlistbox2. In that case, however, since something was previously checked in checkedlistbox2, the selectedindexchange event is also triggered for that one as well because something was changed in that. Can I disable this somehow because technically I didn't "check" or "uncheck" anything, all I did was remove a checked item? I tried doing something like adding an if statement inside the
Ive got a CheckedListBox where I have a list of devices and a checkbox to tell me whether they are on or off. I want to be able to change the checkbox in the program of a specific device and then when I click submit, it to generate a string of numbers to tell me what boxes are checked (1 for on, 0 for off)Example: Boxes 1,3 and 7 are checked in the checkedlistbox, and there are 8 total, so the string outputed would be "10100010".
View 1 RepliesI just can't seem to get this right, what I'm trying to do is use FindWindow to find the windows of more than one window. Here is the code:
app_hwnd = FindWindow(vbNullString, CheckedListBox.CheckedItems)The thing is, if I use .SelectedItem, it only finds one window and if i use CheckedItems/SelectedItems it gives me an error: "Value of type 'System.Windows.Forms.ListBox.SelectedObjectCollection' cannot be converted to 'String'."
So right now, I'm confined to using FindWindow for only one window--when I want to do it for more than one window.

I've written the following class to create CheckedListboxes that use a Natural Sort algorithm. The overridden Sort() method, however, is not getting fired.(The code within that method is from the MSDN example on how to implement your own sort algorithm on a regular Listbox.)
[Code]...
A CheckedListbox derives from a Listbox, so I figured the Sort() override would work, but I'm stuck as to why it doesn't.I am setting the instance's .Sorted = True, but it's just sorting items using the default algorithm, and not the Natural Sort algorithm (which has been tested and shown to work as expected elsewhere).
How can I add checkeditems or one by one items on click from CheckedListBox to TextBox one by one with( ;) between them such as emails in field of mailto ?
