it's possible with vb.net code to show or hide extensions for known file types ? this is a folder option for the new windows 7, wich allow the user to show or hide extensions for files.

Instead of creating a listbox to hold the names of one's favorites, I've made it so when you add a bookmark it adds it under the directory (yourusername)/bookmarks. (yourusername) is represented by login.usernametextbox.text. Now I've added a filelistbox to the form and want it to display the contents of the bookmarks folder only without the file name extensions. Just the title. Then when a user clicks on the title it navigates to that specified file by opening a new instance of a browser form. Here's what I have so far:
Private Sub Bookmarks_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
bmarks.Path = Login.UsernameTextBox.Text + "ookmarks"
End Sub[code]....
I want to extend the BitConverter class with an overload of ToString() that takes a parameter of type Char, representing a value delimiter.Why? By default, the ToString() call returns a string representation of a byte array, delimited by dash symbols. The signature does not allow you to specify a different delimiter, which I find very unfortunate.Now because this is not an instance type, or maybe because I'm overloading a shared method, I'm having a hard time finding the proper syntax to define my extension method.What am I doing wrong here, causing the overloads to not show up in IntelliSense:
Imports System.Runtime.CompilerServices
Module BitConverterExtensions
<Extension()>

I'm wondering if I can change the values in Folder Options, so like "Hide extensions for known file-types" is turned off, can I enable it via code?

I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......

What if you do not know where your program will be, and you are just testing it for now? Is there any way for it to "find" your program, or an easy way to edit where it is opened? For that matter, is it possible to tell if the file has been associated already, is it an issue to try and reassociate? Finally, how can you set the .ico file it uses?

View 7 RepliesInside the program I have a text box in which a user puts in the filepath to a textfile that the program then uses as a series of commands to perform tasks. This works perfectly, however what I would like to to do to make my program faster is associate the file extension .gam with the program, so when a user clicks a .gam file it opens the program and automatically sets said file's location into the text field, as opposed to using the browse button I added and browsing to said file everytime they run the program.
Through this a user could then make a shortcut to said .gam file and run it right from their desktop, as opposed to rummaging around in folders and whatnot. At the moment my method has been thus, I have 2 folders of importance I have archived with the .exe, Gambits Pro.exe, these are: Gambits, and Control, inside of the Gambits folder is the default storage location for .gam files, as when you click the browse button its default directory is that folder. I have also added a few example files in said folder for a user when they download the program.

I am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.
'File' is ambiguous, imported from the namespaces or types 'System.IO, WindowsApplication1.Online.Suite'. whereas Online.Suite is a web reference

View 1 RepliesI've been trying to publish some software for 2 days. At first, I received an error about frontpage extensions not being installed so I installed them, only to screwup the ht.access file on my site and lose my web site for 5 hours.
I had an email this morning from Lunarpages saying they installed the extensions, recoded the ht.access and even tested frontpage on it. SO -- I tried again this morning and still received "the components for the frontpage extensions are not installed". ?
AND --I must be missing something and looked everywhere in VB.NET (options etc) but how in the heck can you publish something directly to your website (I used the wizard and setup all the publish options) and NOT be prompted for your user ID and password? Obviously, VB.NET has it's own ftp program.
