You could try going through VS Debugger (if it is available on that machine). Otherwise I would check for Explorer plugins that are interfering with those two dialogs. Is this problem with all open/save dialogs in the OS? Do you have proper privileges to show those dialogs?

Yup. Tried that. Crashes in "external code", as in the Win32 API.

Well, this machine has a bunch of SharePoint stuff loaded on it. Does that count?

Given that it happens sporadically, not sure. Also, given that the only way to access this computer is with remote desktop (terminal services), that adds another twist to the problem.

Yes.

Do you have enough permission to show them?

I've never seen this before, but I think you might want to try reducing the complexity from your code, and start with just a plain openfiledialog. Then I would add back the custom settings I assume you're using until you find the one that's breaking the dialog box. To be extra safe, I'd probably do it in a test app instead of the program you're working on.
If it were a permissions problem, I would think you're get something more specific than "external exception". It sounds to me like R2 has something in it that .Net doesn't like. BTW, what version of .Net are we talking about, and does your client have the latest version of it installed?

I'm considering that, but in all honesty, this:
OpenFileDialog ofd = new OpenFileDialog();
ofd.RestoreDirectory = true;
ofd.CheckFileExists = true;
ofd.Filter = "rpt files (*.rpt)|*.rpt|All files (*.*)|*.*";
ofd.Title = "Load Report";
DialogResult res = ofd.ShowDialog();
is quite simple already. Sure, I could remove the RestoreDirectory and CheckFileExists options.

If the code that you just posted is what you are using why would their be any errors regarding Win32 API? Is the bug before or after the segment you just posted but only shows symptoms during the ShowDialog method?

The exception happens on the call to ShowDialog.

This is probably totally unrelated to your situation, but I'll
throw it out there just in case...
I just tried your code from C++/CLI on Vista...
int _tmain()
{
OpenFileDialog ^ofd = gcnew OpenFileDialog();
ofd->RestoreDirectory = true;
ofd->CheckFileExists = true;
ofd->Filter = "rpt files (*.rpt)|*.rpt|All files (*.*)|*.*";
ofd->Title = "Load Report";
DialogResult res = ofd->ShowDialog();
...
...and got an exception "System.Threading.ThreadStateException...
Current thread must be set to single thread apartment (STA) mode
before OLE calls can be made. Ensure that your Main function has
STAThreadAttribute marked on it..."
A quick change to this made it work fine:
[STAThreadAttribute]
int _tmain()
{
OpenFileDialog ^ofd = gcnew OpenFileDialog();
ofd->RestoreDirectory = true;
ofd->CheckFileExists = true;
ofd->Filter = "rpt files (*.rpt)|*.rpt|All files (*.*)|*.*";
ofd->Title = "Load Report";
DialogResult res = ofd->ShowDialog();
...
Good luck

Yup, I came across this wisdom why googling about my problem and I did verify that it's there, and just double checked.
Thanks for taking the time for investigating this though! Much appreciated.

And you sure you are calling ShowDialog from the main thread?

Yup. I don't spawn any new threads. The call is being made in response to a menu click event.

Hi Guys

The requirements for this control are that the user must be able to drag files from Windows explor into
a Listbox which appears on a webpage.

I am trying to come up to speed on .Net webservices and have gotten
stuck on a basic issue - I appreciate any clarification.
I can readily create C# applications that can consume webservices as a
client. In that same app, how can I offer webservices to other
clients? For example, so two apps can communicate.
Everything I read about providing webservices has them built into
asp.net pages running on IIS.

|

If you can, take a look at WCF. It allows much more flexibility and does not force you to host the web service in IIS.

+1 on WCF.
If you're using VS2005, you need to update to .net 3.0. If you're using VS2008, you're already good to go.

Hi ,
can somebody suggest good articles to learn how to build a service oriented architecture.
Thanks,

Are you in the correct forum, .NET Framework? If so then you might consider that Microsoft may have published[^] one or more articles eh?

Yes, he's in the correct forum. He could also post in the WCF/WPF forum.

Hello All,
I am trying to create a class library to assist with some Services I have running on a particular machine. I am trying to reference System.ServiceProcess in the class but I cannot find it in the Intellisense and if I try to build the class I get the following "type or namespace ServiceProcess does not exist in the namespace System". I am using VisualStudio 2008 Professional Edition and the funny part is, that if I were to create an app with a UI, I can drag the ServiceController onto the form and use it without a problem. Obviously I am missing something but I don't know what.
Can anyone offer any hints as to what the problem is. I would greatly appreciate any help.
Best regards,
FF

Does it help to know the ServiceController class is in the
assembly System.ServiceProcess.dll?

I need to use Microsoft.Xml.XQuery in .net. Does anyone know from where I can download the XQuery.dll? Microsoft seems to have withdrawn it from their site.
Is there an alternative to it?
Thanks

Is it not built into visual studio ?

I can't find it build into visual studio. The visual studio has the System.XML build in but doesn't seem to cover XQuery functionality. The namespaces are,
using System.Xml.XPath;
using System.Xml.Xsl;
using System.Xml.Schema;
using System.Xml.Serialization;
Microsoft used to provide a download for using Microsoft.Xml.XQuery; but no longer
Thanks

That's a shame. I bought an XQuery book, I guess I'll never use it.
