First, "C:/" is an invalid path. Second, it also doesn't specify a filename.

hi,

thanks for the reply, that was just my many attempts to try anything. this is the original code (which gives the same error):

excel.ThisWorkbook.SaveAs(Server.MapPath("Upload/test.xls"),
Excel.XlFileFormat.xlWorkbookNormal/*xlXMLSpreadsheet*/, Type.Missing,
Type.Missing, Type.Missing, Type.Missing,
Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);

I've tried EVERYTHING. If anyone knows how to take that excel object and send it direcly to the client for download as an .xls that would be equally great.

I'm creating a custom error dialog, and want it to use the same bell sound as an error MessageBox. I tried writing an ascii 7 (BEL) to the error text, but it didn't work and I'm not sure what else to

Hello

You can try to interop MessageBeep for that

How? The example project I found here won't build out of the zip. I fixed the reference to the other project in it, but I can't find the two directX references to readd.

for example, something like this:

[DllImport("user32.dll")]
public static extern int MessageBeep(int type);

and some where in your code:

MessageBeep(0);

Wow, what a strange error. And where did you copy it ? Can you post your code ?

[code]
using System;

using System.ComponentModel;
using System.Windows.Forms;

namespace foo
{
[DllImport("user32.dll")]
public static extern int MessageBeep(int type);

public class FooFrm : System.Windows.Forms.Form
{ /* ... */ }
}
[/code]

1. don't forget about

using System.Runtime.InteropServices;

2. declare MessageBeep in your class as a method.

public class FooFrm : System.Windows.Forms.Form
{ 
[DllImport("user32.dll")]
public static extern int MessageBeep(int type);

/* ... something else ... */ }
}

3. It looks like you need more learning C#

Thanks. And this does fall under the catagory of something I've never had to do before (in any langauge). If I knew the answers I wouldn't have to post the questions. Smile | :)

Yes, I understand you. But still, declaring a method outside class is unknown technique to any language Smile | :)

I found it. IT won't build out of hte zipfile, and while I fixed the problem with the 2nd project not being in the solution, I can't find either dx9 reference to import. Now that I think about it, it's probably a moot point since IIRC the client for this project's running on older windows and is unlikely to have dx9 to begin with.

Could be any number of things. First, can your friend ping your IP address? Is your server application running on Windows XP SP2? Are you running any firewall software on your machine? ...

Windows XP SP2 has a firewall built into it that restricts access to the machine from the outside world. Once again, what version of XP are you running?

You had to mention that word, didn't you...

If your client software can't get through to your server, it won't make any difference what you want or how you want to do it.

I have a problem with checking file permissions. I'm trying to check wether a user can write, read to a specific folder/file but when i test my code it says it can even thou i have removed all permissions. Don't know if the code is correct.

<br />
FileIOPermission filePermission = new<br />
   FileIOPermission(FileIOPermissionAccess.Write,<br />
                    Request.PhysicalApplicationPath+@"test\\test.txt");<br />
try<br />
{<br />
   filePermission.Demand();<br />
   Reponse.Write("Permission demand successful");<br />
}<br />
catch( SecurityException securityEx )<br />
{<br />
  Reponse.Write(securityEx.Message);<br />
}<br />
