Hi folks,

Don't know how to get info about the second dialog which appears after
clicking a button of the first dialog.

following situation:

Dim saveMode As Boolean
Dim saveFileDialog1 As New SaveFileDialog()

' if I clicking the ok button, set value true, pdfreport will be created

If (saveFileDialog1.ShowDialog() = DialogResult.OK) Then
saveMode = True
Else
saveMode = False
End If

for the first time running this it works fine. The next time I start and
click the ok button a new dialog appears with a message "File already
exists, Override Yes/No". After clicking yes the programm runs on at the
else mode, so the saveMode var is set to false.

How can I ask for return values of the second dialog? Any idea?

Hi Joerg,

I did look very long, but I only see one showdialog.

Is there something missing in your message or am I seeing something not (not
impossible)?.

Hello Cor,

the second dialog I mean appears automatically by system (dialog - "File
already exists ... Override Yes/no")

Joerg
 
Hi Joerg,

Do you if you restart the program the same effect when you select an already
existing file?

I did never test this, but I am thinking about something that the pdf file
is not yet closed, so it cannot be overwritten.

Click to expand...

How do you create the PDF report?

Hi,

I have referenced a PdfCreatorLibrary (PdfCreatorLib.dll - Version
1.0.1284.20348 - Copyright(c) Serdar Dirican) and this creates the report

Joerg
 
I think I will do it that way:

Before opening the saveasdialog I ask
if System.IO.File.Exists(file to create).
If is so system.io.file.delete(..)
This works, but not the normal way I think.

Joerg
 
Hi Joerg,
When you know what file to delete, you also know what file to write, than
you don't need the filesave dialog at all I think, something strange..

Cor
 
hi cor,

customers sometimes have to decide, if they use subfolders for save.
Therefore the savefiledialog.

Joerg
 
Hi Joerg,

Customers are always king, but when you first delete the file and then give
them the change to save another one.

Or did I misunderstood you?

Cor
 
Hy Cor,

anyway I don't know how to manage my first described problem. I think it
also wil happen to a standard savefiledialog, if the file you want to save
already exists. In excel this is an error with a errornumber and I can react
for this. With this example I don't know what to do. Some more ideas?

I think something else is up... the dialog code you posted works fine. Did
you happen to trace the code, the results of the test work as far as I can
see.

Thanks Joerg,

Till now I did never use a module, but I am glad you did show it to us.
(A reason more to avoid it)

Thanks,

Cor
 
Hy people,

I was looking for some more msgs describing the same problem. It is
described in detail under the subject savefiledialog. In the MSDN -
Konowledge base is an article under
http://support.microsoft.com/default.aspx?scid=kb;en-us;327213
So all answers I get did ot solve the problem. Clicking Ok and the file
exists returns a dialogresult.cancel no matter if you they yes or no for
overwrite.

Thanks for help
