I have a found that I get different results from the same sub.I created a sub that sets a datsource on a control. When I set the datsource on a combobox on first load of application it returns datarowview as the items IF datsource is set before datamember and valuemember. BUT the checked listbox lods fine..
[Code]...
I could get type of control inside the sub and have them change the order but I am curious why this happens??
I have an application that will be sold to a verticle market. Our techs will do the install, and the software requires hardware for it to work. But I still need to create something so that each customer has a key to use the software. So what is the best way to approach this. I don't high security, because the softare won't do a customer any good without hardware. But it's required in the bids that we do. I also have diffrent options for the software. Not everybody wan't all the bells and whistles, just the basic pakage.I was thinking maybe using a dongel for hardware key? But that more cost.Your thoughts?

View 9 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.
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.

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 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:

theQuery.CommandText = strColumns
theAdapter.SelectCommand = theQuery

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).

View 1 RepliesThe 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)
