Hi!

I created a form with a button. In the buttons code I tried to save the
current document using
thisXDocument.Save();
This will trigger the OnSaveRequest event but when
e.PerformSaveOperation()
is reached, an exception will be thrown.

When I click on the menuentry 'file -> save' the event gets triggered
as well and everything works fine.

It seems that when using the menu, Infopath sets some other values
prior triggering the event.

Am I able to do the same as Infopath? e.g. use some other method than
thisXDocument.Save();?

To give you an overview:
I want to create a form where users can click buttons like 'forward to
approver', 'approve request' or 'decline request'.

Regards,
Benjamin

Hi Benjamin,

When you call the "Save" function (or a number of other functions as well)
through code it requires your form to be "fully trusted." This can be
accomplished by signing your form with a valid digital certificate or by
creating a setup package (with the RegForm tool from the InfoPath SDK)
where your users would need to install your solution.

Here are some links that should be of benefit:

Hi Scott,

thanks for your answer, but my form is alread signed and fully trusted.
I deployed this to a local folder and to a sps list, both the same
problem.

The problem occures only the first time I try to save a new document.

Regards,
Benjamin

When I call the save method within my btnApprove_OnClick eventhandler
in a new document, I get the following exception:
InfoPath cannot save the form.
The OnSaveRequest function returned a value indicating that the save
failed.
The form does not have a file name.

Hi Benjamin,

Ah - now I have a better understanding. When you call the "Save" method,
this is used when the form has been previously saved - as such, the first
time you call this method it will fail.

As you are using .NET, there are a couple of options:

- Display a .NET Save Dialog to allow the user to save the form
- Use a "try/catch" statement and if the save fails, drop to the "SaveAs"
method and hard-code the location

Let me know if this helps!

Hi Scott,
I am using the following code. It's nearly the same you suggested.

Regards,
Benjamin

if( thisXDocument.IsNew )
{
    if( thisXDocument.Solution.URI.LastIndexOf("Forms/") > 0 )
    {
        string url = thisXDocument.Solution.URI.Substring(0,
thisXDocument.Solution.URI.LastIndexOf("Forms/"));
        thisXDocument.SaveAs(url + this.GetFileName() + ".xml");
    }
    else
    {
        string url = thisXDocument.Solution.URI.Substring(0,
thisXDocument.Solution.URI.LastIndexOf("\\"));
        thisXDocument.SaveAs(url + "\\" + this.GetFileName() + ".xml");
    }
}
else
{
    thisXDocument.UI.SetSaveAsDialogFileName(this.GetFileName());
    thisXDocument.Save();
}
