.net - Natural Sorting A CheckedListbox?

Apr 18, 2012

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).

.net - Populating One Checkedlistbox With Another (checkedlistbox)?

Mar 24, 2010

I 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.

Excel Sorting Is Only Sorting One Column Not Multiple?

Mar 12, 2012

I'm having my program sort an excel sheet by a few columns. However, it is only sorting by the first column not the rest that I specify.ere is my sort code below:

myRange.Sort(Key1:=myRange.Range("A:A"), Order1:=XlSortOrder.xlAscending, Key2:=myRange.Range("G:G"), Order2:=XlSortOrder.xlAscending, Header:=XlYesNoGuess.xlYes, Orientation:=XlSortOrientation.xlSortColumns)

Wpf - Sorting Observable Collection Incorrectly Sorting?

Aug 20, 2011

I have a WPF ObservableCollection which is bound to a ListBox and I have a Sort() method which when called will convert the ObservableCollection to a List(Of T), and undertakes a sort based on a date/time column within the collection.

The data is sorted, even when new items are added to the ObservableCollection, however the date/time isn't being correctly sorted. The data is sorting based on the date however it is very much random when it comes to the time portion. The following is an example of the outcomes I am experiencing:

[Code]...

Is there anything that I am doing incorrectly in this method that would cause the time portion not be included in the sort? Is there a better way of doing a sort?

.NET - Database To CheckedListbox?

Feb 22, 2012

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.

2 Columns In One CheckedListBox?

Jan 15, 2012

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?

CheckedListBox SelectedIndexChange?

Dec 15, 2010

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".

FindWindow For CheckedListBox?

Aug 5, 2009

I 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.

Add File Paths To A CheckedListBox?

Feb 4, 2011

The end result I am looking for is I want to add File Paths to a CheckedListBox. I only want certain file extensions and if a file by the same name but a specific extension exsists allready then I do not want to add those files to the CheckedListBox.

Example: I am only wanting these filetypes in my CheckedListBox (.gif, .tif, .bmp, and .jpg).However if the filetype (.PNG) allready exsists with the same filename (i.e. image. png and image.jpg) I then do NOT want to add that JPG. Only files that do not allready have a PNG with the same name. (I hope I was able to make this clear)

My current code will add the filetypes (.gif, .tif, .bmp and .jpg) to the CheckedListBox. However I do not know how to have the code only add the files that don't have the PNG.Here is my current code:[code].....

Adding CheckedListBox To ComboBox?

Jun 9, 2009

I'm trying to implement a combobox that will drop down and give a list of things that the user can select via checkbox so that they can have all, none, or some of the items selected/implemented in the program. Through some research, I've come up empty handed. I found a few tutorials that dealt with tons of class files, which I'm not really familiar with, didn't understand much, and then didn't work. Who would've thunk it right?Anyway, i tried just adding the checkedListBox as a control to the comboBox and it would disappear from the form as if it had been added, but wouldn't show up from the comboBox drop down menu..can anyone tell me how I can go about doing that?

CheckedListBox With One Bolded Item?

Mar 28, 2011

I have an application that uses a treeview and a checkedlistbox to allow a user to navigate and enable/disable printers on their computer. Everything works great.One of the program requirements is that the user interface must visually indicate which printer is the users default. The obvious best way to do this is by changing the font of the item in the listbox that matches the users default printer. From my research, it seems that I will have to subclass the checklistbox and add the drawmode property to the new control. I've got no idea how to do this with a checkbox and make it actually work!

Forms :: CheckedListBox Set From File

Jul 30, 2009

I am an ad-hoc VB application writer to ease my day to day office activities. I started with VB6 and now using VB.net 2005.

I have a CheckedListBox (chkList01) with 130 items. By default all items are checked. Every 5min would like chkList01 to refer to a text file (list.txt) and update the checked state. The list.txt file will have a value per line (True or False) for all 130 lines. An external application will update the list.txt file every 5min.

So every 5min my application will refer to the list.txt file, and row by row see if the value of the row is true or false. If the row value is false then it will change chkList01�s checked state to false.
