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?

I need to create a checkedlistbox that has multiple columns and each column has a header. Is this possible? I can't really find much on Google. Here's the headers I need:
Checkbox Title Existing path Destination path
I have created these columns to the checkedlistbox I have in my form, but when it is run the headers don't show up. Also the items I'm adding don't seem to abiding to the column widths I put in. Also with the code I'm providing below the items don't display as multiple rows, meaning each item doesn't get displayed on a new row, but in a new column.
vb
For i = 0 To iMovies
Movie = New MovieItem()
Movie.tmdbid = CInt(StrBetween(moviestag, "<tmdbid>", "</tmdbid>"))

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.

My goal is to connect to my database either manually or using an sqladapater, and get information from two of my databases on sql server 2005. Then I want to take this information and on run-time begin to add/subtract/divide/multiply certain columns and place the information into other columns. I can do this in queries, however, I want to do it on run-time what is the best way to achieve this.I had some of this working, but I just want to start fresh and see how you would go about doing this.

I am using the following code to alter an table imported from an Excel spreadsheet
Dim SQL As String = "ALTER TABLE receipts ADD payee integer, account integer, category integer, reconciled boolean"
Dim dataread As New OleDb.OleDbCommand()
dataread.Connection = Connection1
[code]....
Both ExecuteNonQuery() actions yields the exception message {"Syntax error in field definition."}The error message does not happen with the first if the boolean column is not there (I tried Tes/No as a definition - but that also failed.The second query to modify the ID column from autonumber to integer I assume fails because it is a Primary KeyHas?

I've the following code which successfully makes an average for all the columns from a table. What I need to do though is ignore certain columns in this equation.
Dim totalNumber as Double = 0
Dim count as Integer = 0
For x = 0 To xyz123.Tables(0).Columns.Count - 1

I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable

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 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".

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.

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).

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].....

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?

I have a data table (cv_dtPools) that contains six columns.I only want to load two columns from cv_dtPools into CheckedListBox.I want vchQCID to be the DisplayMember and "intQCPool_PK' to be the ValueMember. When the user is done selected the items in the CheckedListBox they will then click a button.The code behind the button will then collect the ValueMembers (intQCPool_PK) and put them in another data table which will be used by another procedure.How can I get only the two columns of the data table into the CheckedListBox?
