Changing Items Shown In Explorer Combobox Of File Dialogs?
Jan 13, 2010
In my dialog I want to prevent the user to browse freely in certain places (this is due to the fact that my application will be running in a terminal server environment). So I want to to limit the items that will be visible in the top combobox of the server. I want it to start with "My Computer" instead of the usual "Desktop". Furthermore I only want to add mapped network drives under "My Computer" so that the user won't be able to see any local resources.With Spy++ I have been looking around at what happens when a FileDialog starts.
So far I have found that for each item in the combobox CB_SETITEMDATA and CB_INSERTSTRING methods are executed. By using a hook to the combobox I am able to intercept these messages, but sofar I am unable to determine the exact contents of what is inserted, so I am unable to determine wether it is the "Desktop" item or not.I have also discovered that the "My Computer" node is only added at the moment that the combobox is expanded. So I would need a way to get a handle to "My Computer" and insert an item for it manually

I just downloaded the latest VB Express. It seems that thought the functions are available, there are many that are not as fully functioning as they should be, like PRINT dialogs and TIME/DATE dialogs, etc. Are some of these functions not fully developed in VB Express because they are only available to the licensed version?

I'm looking for a simple and easy way to retrieve the names/descriptions of all the volumes *exactly* as they are shown under My Computer in Explorer.
For example:
System (C:)
Data (D:)
Removable Disk (F:)
[Code]...
I don't want to emulate it, because there are too many settings which can influence the view (ShowDriveLettersFirst, autorun.inf, desktop.ini, DriveIcons, MUI, etcetera) and I need the exact match.
I'm guessing it requires a P/Invoke to shell32.dll or something, but I haven't been able to figure it out yet.

I am making a program that is in need of labels changing and showing depending on what the user clicks on a file Dialog.
Everything works fine except for that when I change the labels, it uses the entire file path, and I ONLY want the file name. How would I be able to get JUST the file name?

Once a user has selected a file with the open file dialog, how can I handle this action? For example, if the user has selected a .txt file and has opened it, how can it get the data from the file? How can it return the path that the user found the file in? Then, how can it save the file?I know that there is a OpenFileDialog.OpenFile() method, but I am also pretty sure this is not what I am looking for. I have also tried the ToObject method, but I probably messed up somehow.

What the icon file filter is for load/save file dialogs. (I know the jpeg one is "JPEG Files (*.jpg)|*.jpg|PNG Files (*.png)|*.png|BMP Files (*.bmp)|*.bmp|All files (*.*)|*.*" But as far as I know you can't use these as icons without an icon editor).

basically i'm making a webbrowser, and i want it to select and option from a dropdown ComboBox, on a certain button click. I use this code which i found it on these forums as well:
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("select")
If element.GetAttribute("id") = "wrapper_opacity"
element.SetAttribute("value", "51")[code].....
The problem with this code is that it just inputs the selected value, but it doesn't really SELECT it.The option selected is shown, but not activated.

Is it possible to control the height/number of items shown in a select dropdown box? Or do I need to code a custom widget? Is this possible?
Forgot to mention I'm using the following code:
<asp:DropDownList runat="server" Width="288px" CssClass="Select"></asp:DropDownList>

I want to make a program that is similar to Windows Explorer. It will have a button that when you click it it opens a FolderBrowserDialog and it will have an area that displays the contents of the selected folder. I want to have a label that displays the current folder path (i.e. 'USERDocuments...') and I also would like a feature to search all files on the computer.Also, is it possible that when I click on a file in the contents of the selected folder it displays its information (i.e. Name, Size, etc.)? And can I also make it so that if you double click on another folder in the current folder's display it opens that folder? And can I have a button to go up one directory?

I am creating a Windows Application in VB.Net 2.0. The application is an FTP transfer application, where I need to display 2 panes. On the first pane, I need to display the client folder structure and on the other pane, I need to display the remote FTP server. Most of the functionality is complete, but I am stuck on 2 places.
1. I need to display a combo box on top, similar to the one we have for Windows Explorer Address bar (where we can see My Computer, Desktop, Network Places, Drives, etc.). I have searched a lot but could not find something matching my requirement other than a few 3rd party controls which I need to purchase (I am looking for something open-source).
2. I am using ListView Control to display the files list. I need to show icons for "My Computer", Network Places and desktop on the List View, which I am not able to do. Is there any way I can display these Icons and make them work exactly the way Windows Explorer does?

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")
