I am populating a listbox from a table called "TableA" and if item is checked in the listbox it is saved in another table called "TableB"
For i = 0 To listbox1.Items.Count - 1
If listbox1.GetSelected(i) = True Then
rs.addnew ..........' (in TableB)
[code].....
What i am trying to achieve is that if listbox2 contains checkedlistbox1 items then checkedlistbox1 should retain checked state even after the from is closed and re-opened again.
Since i am saving the checkedlistbox1 values into a Table - is it possible to bind those to retain the checked state even after the from is closed and re-opened again - or it can be done comparing the values from both listboxes [code]...
I am populating a Checkedlistbox "lstExpert" from table "TableA" succesfully. Whenever an item is checked in the Checkedlistbox "lstExpert", i am saving it into another table "GroupExpert".
[code...]
Is it the right way to do by comparing index in Checkedlistbox "lstExpert" and "Listbox1" Is there a way to bind it directly to the table "GroupExpert" meaning if the value of the Checkedlistbox "lstExpert" is present in the "GroupExpert" then the item will be cheked... I tried the following code and nothing seems to work.[code...]
My assignment is to create an application that allows the user to type an item's price into a single textbox, add the price to the previously entered prices, and display the total charge which includes a $15 shipping charge and a 3% sales tax.Example: I type 10 in the textbox and click calculate. the subtotal (before tax and shipping) reads $10. Next, I type 20 in the textbox and click calculate. The subtotal should now read $30.I have everything working fine except adding the different prices. I cannot figure out how to retain the value of the subtotal and add it to the next value entered.

View 2 RepliesI have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

In my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

I need to allow labels in disabled panels to retain a their prominent forecolor. So, I am considering replacing all labels in panels that become disabled with LinkLabels. By disabling the control and setting its disabled color to black it holds the color. However, I have always been of the opinion that one should use the lightest control possible.
View 3 RepliesWe have an ASP.NET application that queues some of its long-running operations (generating reports, for example) into the ThreadPool using System.Threading.ThreadPool.QueueUserWorkItem.
We run the ASP.Net application pool using a specific domain service account so that it can access remote resources, including files and databases. When the execution starts in the ThreadPool, the user identity of the thread is set to Network Service, which doesn't allow us to access the remote resources.The web application can be accessed by users in different countries simultaneously and the format of the data that we provide to each user is based on their culture settings (using the standard globalization settings in web.config). When the queued thread is started, it has also lost this information and reverts to the default culture for the operating system.
Now, we can probably get around most of these issues by capturing the current user identity and culture in a state object and passing that to the background worker, then impersonate the user and set the culture on the thread, but this seems like a very "unclean" way to resolve this issue.[code]...
I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.
View 1 RepliesI have a DataGridView, bound to a dataset. All the columns are sortable (.ColumnSortMode.Automatic). The user may change data in certain columns, although not the first ("key") column. When data gets changed on a row, I change the backcolor for that row (to show it as dirty). At some point, the user will do something with all of these changes.
My problem is that I still want the user to be able to resort the data by any of those columns. When it's sorted, though, I lose the backcolors that I changed. I do know which rows are dirty, this is just a cosmetic issue. Isn't there a way to retain those backcolors, or any other such row attribute?

So I open files and do whatever with them right. I've set the initial directory to equal the last directory, but whenever I open multiple files, it never sets the directories properly. It acts as though nothing was opened there, so it takes the previous directory as the last one. Thoughts on what's not working? Here's the code.
Code:
With FileOpenDialog1
.InitialDirectory = LastDirectory
If .ShowDialog = DialogResult.OK Then

I have multiselect enabled earlier and everything else works but this. When you open a single file, the last directory works fine. It only happens with multiselect.On another note, does anyone know why it freezes when I try to do a lot of files and use another program? I opened 700+ files to see what would happen. When I switched to a IM convo, it froze. When I left it to run, it worked.
If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False

1 when my listbox returns resaults it only brings back 10 how do I set it to return lets say 500
and question 2 is when I click on my links in listbox it's not opening webpage as I would expect it...
This is my code
[Code]...
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesThe scrollbar that comes with the ListBox is too small for touch screens, so I use my own scrollbar instead. But when you do this on various forms you end up repeating a lot of code. So my solution was to create a custom scollbar that has a property I can set to the control I want it to be a scrollbar for. In vb6, I can use the withevents keyword to get access to the control's events so that all the scrollbar related code can be in the custom scrollbar object I created, except...I had to create a refresh method for the consuming code to use to let the scrollbar know when the number of items changes. The scrollbar doesn't need to be told how many items there are because it has access to the control, but for a listbox there is no event to tie into when an item is added/removed so not 100% of the scrollbar related code could be encapsulated.
