Hi all,
I have render a report on WebService layer and send it to WinForm Application layer as an byte array. After getting the array on the Application Layer, I want to show a Open/Save/Cancel dialog like lots of web sites use and enable the users open or save this report. As I want to create my reports on the WebService layer, I think I do not use ReportViewver easily. Do I? So, how can I show an Open/Save/Cancel dialog for enabling the users to choose this options?
BR

//On the Application Layer (Windows Form) :
private void GetFileFromArray()
{
    try
    {
        // call web method and store the result
        byte[] GenItineraryResult = myService.CreateReport(); //returns created report as an byte array
        using (FileStream fs = new FileStream(@"c:\Report.pdf", FileMode.Create))
        {
            fs.Write(GenItineraryResult, 0, GenItineraryResult.Length);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    finally
    {
        fs.Close();
    }
}

Solution 1

How about this code:

C#

OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    var file = ofd.FileName;
    // Write your file using the filename provided
}

Thanks for reply Alex, but it is only Open dialog. Instead of this, I need a Open/Save/Cancel dialog as we can see most of the websites when clicking a pdf file that enable us to Open or to Save the pdf file and Cancel also if we want.

I am not sure if there is such a dialog built in. I belive the open/save/cancel is a dialog built into the browser.

What browser?! The question is tagger: WinForms.
Please see my answer.

The OP was describing the situation when the user is presented with that choice on many web sites - which means browsers.

As I have already said, there is no built-in dialog window that the OP can use. You have to build your own.

Please don't lash out at people if you did not read the full question or reply.

There is not a ready-to-use combine Open/Save Dialog. It's enough look at the help MSDN pages for the library you use (Windows.Forms tagged) to see that there are two separate classes in each: SaveDialog and OpenDialog. There is never no a need for combined behavior, so using two separate classes is just fine.

Also, the file dialogs have nothing to do with file I/O. They merely provide a file name for the file to be stored or loaded. So, you had no need to ask anything specific to PDF or any other type of file; this is irrelevant. You only can set a FileMask to filter file properly while browsing.

That's all.

See all six classes:

To add to what SA said, ultimately, it's trivial to create your own dialog, and it sounds like you want to create a dialog, asking the user if they want to open or save the file. The browser dialog does this first, then shows a save dialog if needed.

I would add that you have to save the file to disk anyway before you open it.
