SaveFileDialog-problems

[Rikard Bosnjakovic]

Greetings

I'm new to both .NET and Visual Basic, but I've got experience of
developing Windows-application earlier (w/o .NET or any framework).

Consider this code:

Private Sub Button1_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button1.Click
Dim dlg As New SaveFileDialog
Dim res As DialogResult

res = dlg.ShowDialog( )
If res = Windows.Forms.D ialogResult.OK Then
MsgBox(dlg.File Name)
End If
End Sub


The *only* thing I want from this function is the filename that filename
that the user picked inside the dialog.

However, I get an exception in mscorlib.dll of type
"System.Securit y.SecurityExcep tion":

=============== =============== =============== =============== ============
Request for the permission of type
'System.Securit y.Permissions.F ileIOPermission , mscorlib, Version=2.0.0.0 ,
Culture=neutral , PublicKeyToken= b77a5c561934e08 9' failed.
=============== =============== =============== =============== ============

As a tip for troubleshooting , Visual Studio tells me to use the OpenFile
method to open or save a file. But this is not what I want, I want the
filename only.

Also, issuing something like dlg.InitialDire ctory = "T:\" throws the same
exception.

So, I'm running into these tedious problems that I'm unaware of why it's
happening. Visual Studio tells me some file is not trusted or whatever. I
certainly don't give a ditch, but I guess there's some for me unknown
reason for this.

I would be grateful if any could straighten it out and explain why it's
happening as it does.

Thanks.

Rikard,

I am too always in trouble with that dialog those boxes return, can you try
it this way.

Dim dlg As New SaveFileDialog
if dlg.ShowDialog <DialogResult.C ancel then
MessageBox.Show (dlg.FileName)
end if

I hope this helps,

Cor
