Reload Multiselect Listbox Controls?
Oct 4, 2010
I have a multiselect list box on a Windows form (VS 2008) containing references to 35 different work stations. The end user can select any number of workstations in this listbox, then store those selections to a SQL table (this part is working fine). The problem is getting those same workstations highlighted/selected when the user recalls that record from the database, in the event that there are addtions or changes. Here is the relevant code for the reload[code]...

In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?

Background: I have a winForm app that registers a user in the database based on the user input provided in the form, auto-generates a random password and username for the user, and e-mails the user a link to take an application based on the marketing company selected.
Problem: I got the bundles listbox to populate w/ autopostback set to true but the bundles listbox populates as soon as you click on an lbcarrier and it doesn't allow you select more than one carrier.how to allow multiselect with the postback feature on? Here's a screenshot of the interface:
code on default.aspx:
<td class="style1">
Carriers:</td>[code].....

Here is the basic problem. When a listview is set to multiselect = true, the electedIndexChanged event fires for every row. This is very bad in a situation like the following psuedo code:
MultiSelect in listView (many items)
Clear any items that are selected in GridView
find that item in gridView using a brute force compare
[code].....

In WinXP with LV FullRowSelect enabled I can press and hold down the left mouse button and drag it down the right side of the left-most LV column and the rows are selected, but under Win7 I can only multiselect items with the mouse if FullRowSelect is set to false.
So I guess I need to write code to support this sort of feature for Win7 ? , and if true are there any code examples (I can't find anything) to save me some time?

i have a vb script that is imbeded in an html page (hta). when i use the common dialog flags = cdlOFNAllowMultiselect the file list is present in the filename object and are separated by a space. however when i use dialog flags = cdlOFNAllowMultiselect Or cdlOFNExplorer the files that i selected on the dialog box, are not present in the filename object. the only thing that's there, is the path to the files. here's the code:
Const cdlOFNAllowMultiselect = 512Const cdlOFNExplorer = 524288Set ObjFSO = CreateObject("UserAccounts.CommonDialog")ObjFSO.Filter = "All Files|*.*"ObjFSO.FilterIndex = 1
ObjFSO.InitialDir = "c:" ObjFSO.Flags = cdlOFNAllowMultiselect or cdlOFNExplorerinitFSO = ObjFSO.ShowOpen selected_files = ObjFso.FileName msgbox selected_files
how can i get the files names?

I have a gridview that is only shown in a modal popup. right before I call the modal popup I set a value in a textbox. The gridview inside the modal popup depends on that textbox's value for it's data to show up at all. SO onclick I want to reload the gridview so that it will reload with the textbox's value.

I have a setting labeled "Names" and in the program I can create a new "Names" value, which works fine. But, I want to be able to automatically save to this new "Names" and retrieve information from the value without having to close the program and reopen it in order to have the new setting saved. Is there a way to do this? I tried using the Me.Refresh() command, but it didn't do the trick.

I have a application that requires access to a tablet, the tablet in order for it transfer data accurately needs to be calibrated from time to time. Users have expressed intrest that once calibration has been done and has been validated to be correct that
those new settings be ready for use in the main application. However, the only way I have been able to do this is to physically re-start the application. I have not had any luck with My.Settings.reload(). The settings I can confirm have changed but the application after saving them and calling the reload do not reload them. Am I doing something wrong? Does reload only work under certain conditions?

I have a session variable that changes some things about how a page looks. I have a button that changes the value of this session variable. But ... the onClick event happens after page load, so by the time I update the session variable based on the button click, it's too late, the page has already been loaded.
Theoretically I could put all the logic about changing the display into a function and call it from page load, and then call it again from the onclick after the variable as been updated. But this is impractical: there are many user controls that check the value, used on many different pages in different combinations. I would have to hard-code the list of user controls on each page, and if someone added a new user control to a particular page, they'd have to remember to update this function, which is lame.
Is there a way to force a page reload? (I can use response.redirect back to myself and it works. If all else fails I guess this is what I'll do. But it means an extra round trip to the server, which is clumsy.)
Is there a way to process the onclick before the page load?

Is there a way to force a form to reload itself? The reason I ask is I have a listview that shows the data from my database. You can add information to the database from another form but when you go back to that form the information is not updated because the information updates on the form load. So my question is there a way to just do the form_load event again?
