version of .net + folder browser

Re: version of .net + folder browser

Juli Jul,

Did you try this one
{
FolderBrowserDi alog fb = new FolderBrowserDi alog();
fb.ShowDialog() ;
MessageBox.Show (fb.SelectedPat h);
}

I thought that I told you in a previous version that the standart Net 1.1
version has a bug which is repared in Net SP1. However this it has to do
withouth that as well when your paths are shorter than 128 characters.

I hope this helps?

Re: version of .net + folder browser

Define "normal folder browser". The options are the
System.Windows. Forms.FolderBro wserDialog or to use the SHBrowseForFold er
function in the Shell32.dll.

Re: version of .net + folder browser

Hello,
with the normal folder I mean the :
System.Windows. Forms.FolderBro wserDialog folderBrowserDi alog1;
I tried to do the ShowDialog() method and all I can see is still an
empty window with no folders to choose.
Could someone help? Thank you!

Re: version of .net + folder browser

Hello,
Could you please explain how to use the STAThread and how do I implement
the folder browser with it?
Thank you!

Re: version of .net + folder browser

Hi,

If my guess is correct. Change the attribute [MTAThread] to [STAThread] In
the Main function.

If you have to use MTAThread, the only way to show the folder browser is use
the SHBrowseForFold er function in the Shell32.dll.
Though this function doesn't support 'Make a new folder' button when you use
MTAThread.

The website http://www.netomatix.com/FolderBrowser.aspx might help you to
wrap the FolderBrower class.

Re: version of .net + folder browser

Hello,
I tried to make a new project with only the folder browser in it and it
works there but inside mine project it doesn't.Is it possible that this
control can't be at the same form with some other control?
Are there some kind of sources with which I could implement the folder
browser some other way?
Thanks a lot!

Re: version of .net + folder browser

Hi, Juli

To implement your own folder browser, That is a lot of work. personally I
don't think that is a good way to do.

What type is project? Windows Application? Please dobule check what
attributes applied to Main function.

Another way to identify if it is MTAThread problem. On your new test
project, change the STAThread to MTAThread; if you get the same result as
your project does, just change the attribute should fix your problem.

Help this helps

Re: version of .net + folder browser

Hi, Juli

I can give you 2 ways to check the COM threading model.

1. find your Main function, you might find there are attributes applied to
the Main function, usually it looks like
[STAThread]
static void Main()
{
...
}

2. If you are not able to get your Main function source (I presume the
source file is owned by somebody else), you still can get the current COM
threading model by calling ApartmentState in Thread class, it looks like

using System.Threadin g; // you have to add this namespace

ApartmentState state = Thread.CurrentT hread.Apartment State;
// you can set breakpoint here to check the value of state. or pop up a
message box to display it.

Add this code just before your call ShowDialog function, you will know what
COM threading model the FolderBrowser is running on?

Re: version of .net + folder browser

The messagebox result was that I have a MTA attribute-what does that
mean and should I change it (and how) in order to see folders in
browser?
Thanks a lot!

Re: version of .net + folder browser

You have to change the attribute in Main function, it should look like
[STAThread]
static void Main()
{
.....
}

find your Main function, you will notice that there is [MTAThread] attribute
just before Main function; Change it to STAThread, the FolderBrowser should
work. It is just like what I said at very beginning.
