I really like this dll, but was wondering if it was possible to have the buttons as an optional separate control (So that you could hide the buttons and instead use a control to have the buttons in another location, or along the top, etc.). I was also wondering if it was possible to change the images for the buttons. I'm more curious than anything.
Thanks again for a great dll. This is a godsend.

I don't remember anything being built-in to support this, however the source code is included and is license free, so please feel free to modify it for your needs. Maybe I'll revisit this control someday and bring it up to 2.0 since it still seems to be popular.

I read the discussion by FauthD dated 12:07 18 Oct '05 about the visibility of the TextChanged event. I have the same problem.
I don't completely follow Fauth's explanation of the workaround. I would like access to the event. Any advice?

I downloaded the source, compiled it, copied the dll to my source, and added a reference to it.
So how do I get it to show up on the toolbox so I can use it?

Right click on your toolbox in VS
(If you want to, make a new tab)
Choose to add items
Choose Browse
Browse to the dll
OK your way through
The components will now show up in your toolbox
Drag and drop them on the form

I've notice that after browse for folder or for file, the current Application directory is changed to the selected folder.
To solve this problem, i've added two lines of code, in the function btnSearch_Click
At the start of the function
string sCurDir = Directory.GetCurrentDirectory ();
And, at the end of the function
Directory.SetCurrentDirectory ( sCurDir );
Regards

Hi,
in my case I need access to the list box and as a QnDirty solution I made it public.
I think it would be better to expose a more general interface for this, but I am not a basic guy (..,C,CPP,MFC and now a bloddy beginner in C#)
Many regards, Dieter

Hi,
I needed an event that fires after all items have been added. So I created the event ItemsAdded and called RaiseEvent for it after all loops containing the event ItemAdded,
The code is to much to post here (few places), but you get the idea.
@Todd: send me a p-mail, then I can mail you the files..
I also added the "preloading current path/file" extention I did for the BrowseField.
Thanks for this class, Dieter

Hi,
in single slection mode you will get an exception (out of range). The reason is that the SelectedItem is invalid in the second time of the loop. (the count does not get decremented)
I added an exit in case it is single selection mode.
Warning: I had no time to check the other selection modes.
Private Sub PictureDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureDelete.Click
While ListBox1.SelectedItems.Count > 0
ListBox1.Items.Remove(ListBox1.SelectedItem)
RaiseEvent ItemRemoved(Me, e)
If (ListBox1.SelectionMode = SelectionMode.One) Then
Exit While
End If
End While
End Sub
Good luck, Dieter

Hi,
the event does not show up in the event list of the form.
it has something to do with the name of the event.
Renaming to xTextChanged for example does work.
As a workaround I build this event in. it is even better for my app:
Public Event TextValid(ByVal sender As Object, ByVal e As EventArgs)
in Textbox1_TextChanged:
If TextIsValid(Text) Then
RaiseEvent TextValid(Me, New EventArgs)
End If
and the whole sub:
Private Sub Textbox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If _BrowseType = BrowseTypes.File And _FilenameOnly And Text.IndexOf("\") > -1 Then Text = Text.Substring(Text.LastIndexOf("\") + 1)
RaiseEvent TextChanged(sender, e)
If TextIsValid(Text) Then
RaiseEvent TextValid(Me, New EventArgs)
End If
End Sub
Thanks for this class! Dieter

Hi,
all my programs must be user friendly. One part of that is that paths and filenames must be stored in registry and be shown the next time. For that I use the iProfile class from Alvaro Mendez (http://www.codeproject.com/csharp/ReadWriteXmlIni.asp).
A small change is required to to the BrowseField to expose the stored values to the user:
I just added two lines (one for files, one for folders) before the control actually gets opened:
OpenFileDialog1.FileName = TextBox1.Text
FolderBrowserDialog1.SelectedPath = TextBox1.Text
Not sure if that will show nice in the forum:
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
If _BrowseType = BrowseTypes.File Then
OpenFileDialog1.FileName = TextBox1.Text
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
TextBox1.Text = OpenFileDialog1.FileName
End If
Else
FolderBrowserDialog1.SelectedPath = TextBox1.Text
If FolderBrowserDialog1.ShowDialog() = DialogResult.OK Then
TextBox1.Text = FolderBrowserDialog1.SelectedPath
End If
End If
End Sub
Thanks for this class! Dieter

 Nice control.
The icon only shows up if you add it to your toolbox from the DLL. It will not show up in the My User Controls section.
Here is the code with the "Caption" fix, tooltip, and file validation. Add a tooltip (Tooltip1) to the form, then you can copy the code.

End Sub

Lookup "ToolboxBitmapAttribute[^]" in the MSDN Library Documentation.
Change your class declarations as follows:
From
Public Class BrowseField
<ToolboxBitmap(GetType(BrowseField), "BrowseField.bmp")> Public Class BrowseField
and From
Public Class BrowseList
<ToolboxBitmap(GetType(BrowseList), "BrowseList.bmp")> Public Class BrowseList
The icons will still not appear in the "My User Controls" Tab of the Toolbox, but when you add them manually to any other project (via the "Add/Remove Items ..." context menu item) you will see them.
Hope this helps.

Thanks for this suggestion, and the one on resizing. I will try them both, and if they work, I will upload those changes (and credit you in the code of course). Thanks so much!
I hope the controls were helpful to you.

Perhaps you should just not set the width of the controls 'by hand' when AnchorStyles.Right is set?
Suggestion: Insert the following lines at the beginning of BrowseField_Resize resp. BrowseList_Resize.
If (Me.Anchor And (AnchorStyles.Right Or AnchorStyles.Left)) = (AnchorStyles.Right Or AnchorStyles.Left) Then
Exit Sub
End If
Hope this helps.
Cool piece of work anyway. (Got my 5)

First of all I love the control it has helped me alot.
I am having some problems with changing the properties of ListBox, I had to change the selection mode in the initialization code because it was not applying the value set in the properties list.
Also I am trying to change the ListBox to an OwnerDrawFixed mode, so I can colorize the strings, but that event is not firing.
Great job just a few quirks left.

Thanks, glad it is helping you out, at least somewhat.
I had the same problem with the properties, if I tried to set them through the designer. Even if they "took" once, they would dissapear after making some other change in VS.NET. I think this is a problem with VS, but either way, it's a pain.
I started work a newer version of these controls that had more features, but the biggest feature is that all the properties are being properly overridden, so you won't have to do this:
BrowseField1.TextBox.BorderStyle = BorderStyle.FixedSingle;
Instead, it will look more like this:
BrowseField1.BorderStyle = BorderStyle.FixedSingle;
I don't know when this be available. I started working on it a few months back, and then my "day job" got real busy, so I haven't put much time into it. When it is done however, it will be updated right here in CodeProject.

Any idea how i can get the ownerdraw working for the list box?
I thought it would be a simple line like this but apparently not:
this.CompareToList.ListBox.DrawItem += new System.Windows.Forms.DrawItemEventHandler(ListBoxDrawItem);
Thanks again.

Acually nevermind my response, I dont know why I didnt try this before, I just programatically set the draw mode and it works fine.
Fantastic work. Keep it up.

First of all control is great. I do get exception: DragDrop registration failed. What I do is:
- Create a new windows form MyForm
- Drop BrowseField from my toolbox on the form
- Write this code to use the form:
MyForm mf= new MyForm();
DialogResult dr = mf.ShowDialog();
At ShowDialog I get exception: DragDrop registration failed
What should I do to use it2
By the way I work on WinXp SP2 and .NET 1.1 Sp1.
Thanks.
