Using .NET 3.5, SQL Server 2005 and C# 2008 Express.
Server creates instances of the server-side code.
Worked fine under XP. Upgraded to Windows 7 and the remote calls hang.
If I add code to my client which accesses the database directly (inserted before it does the remote call, it works. But not remotely through the server.
Is there something I should know about SQL Server/.NET/Windows 7?
|

|
|
|
The information you provided is not enough. What is your app doing and where does it hang ? And what does remote call mean, WCF, Web Service or a remoting component ?
|
|
|
|
|
Not clued up on terminology, so will give examples.
The first step that the app does is collect the username and logon, and then check if they are in the database.
I am using interfaces to the server-side code, and the server creates instances of the code like this
UserList insUserList = UserList.Instance;
ObjRef refUserList = RemotingServices.Marshal(insUserList, "UserList");
The client does a call like this
private IUserList rmUserList;
rmUserList = (IUserList)Activator.GetObject
(typeof(IUserList),
System.Configuration.ConfigurationManager.AppSettings["UserListUrl"]);
logonReturnValue = rmAllUserList.Logon(PasswordString);
UserListUrl is tcp://localhost:50050/UserList
On the server side it does (through calls to a pool of common routines, also on the server.
cnStr = "Data Source='NIGEL-PC\\SQLEXPRESS';" +
"Trusted_Connection=true;" +
"Database=timesheet";
cn = new SqlConnection(cnStr);
cmd = new SqlCommand("", cn);
da = new SqlDataAdapter();
cmd.CommandText = "SELECT Password " +
"FROM UserList " +
"WHERE UserID = 12 ";
da.SelectCommand = cmd;
tmpDS = new DataSet();
da.Fill(tmpDS, "Data");
If I run the above code snippet in ClientLogon it works. If I allow it to do the remote call, it hangs.

|
|
More info:
On the server side, I created a routine that only returns a string "OK", with no data access. Still hangs, so it is definitely the remoting bit, not the data access.

If anyone is interested, the problem was with Comodo Internet Security, even when diasabled.

Probably you'll need to redelete and recopy every programming session.

Can't find it using search.
I can generate the .snk file using sn.exe -k. But I have forgotten how to generate the .pfx file. I upgraded to Windows 7 so of course I have lost it, and now when I compile I have to supply the password for every file in my solution!!
|
|
|
|
|
Hi,
I had the same problem and as far as I remember, I created a new pfx with the same name + known password and replaced it.
|
|
|
|
|
That is exactly my problem - how do I create the pfx file?
|

Create a new project (a dummy one) in the project properties go to the signing tab, click sign this assembly, under the choose name key label, select new from the combo box and create it. There is a manual way to make it from command line but right now, I can only trace back this one.
|
|
|
|
|
I am starting to remember now. And then you say "Password protect it". Ta.

hi
i used the following code..
-------------------------------------------------------
Microsoft.Office.Interop.Word.ApplicationClass wordApplication = new ApplicationClass();
object o_nullobject = System.Reflection.Missing.Value;
object o_filePath = "C:\\bok_doc.docx";
object o_format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatHTML;
object o_encoding = Microsoft.Office.Core.MsoEncoding.msoEncodingUTF8;
object o_endings = Microsoft.Office.Interop.Word.WdLineEndingType.wdCRLF;
object o_Readonly = true;
Microsoft.Office.Interop.Word.Document doc = wordApplication.Documents.Open(ref o_filePath,
ref o_nullobject, ref o_Readonly, ref o_nullobject, ref o_nullobject, ref o_nullobject,
ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject, ref o_nullobject,
ref o_nullobject, ref o_nullobject);
Microsoft.Office.Interop.Word.Document doc1 = wordApplication.ActiveDocument;
string m_Content = doc1.Content.Text;
// sp.InnerHtml = m_Content;
// the content is stored into the textbox.
//TextBox1.RenderControl(
TextBox1.Text = m_Content;
------------------------------------------------------------------------------------------------------

Print the Word doc on the fly to an XPS document, and then load the XPS document into a WPF DocumentViewer control in a WPF window or host the Viewer in a Windows Form.
|
|

hi
would you please provide me the detail to how i can resolve the problem..
since i had never used the XPS format ..
and how i will be reading that format using asp.net (C#)..
to display the content in the textbox.

You didn't mention that you were using ASP.NET in your original question.
Since that's the case, just open the Word document in an new IE Window and forget about using a control. XPS documents can be opened in IE also; so, no difference in that case.
(And I said to use a "DocumentViewer" control for XPS; not a TextBox. In any case, a DocumentViewer can only be hosted in Windows).

Of course it doesn't work! First of all, the TextBox control doesn't know anything about Word formatting and cannot render what it doesn't know how to do. Second, you're getting only the text from the Word document, not the formatting.
Basically, you can't do what you want using a TextBox control.
|
|
|
|
|
Save the word document as RTF and use RichTextBox to display the content.
|
|
|
|

hi
Do we have the richtextbox control in asp.net 3.5..
would you please guide me the way i can achieve this..

I was talking about Windows Application. There is no way (as far as I know) where you can interactively display Word document on a web page.
You may try to convert the Word doc into html format and display it in an iFrame.

It seems you are using a COM component to recognize speech. In that case, you have to add a reference to the COM component in VS and it will create a RCW for you. And then remove error handling from the procedure that is giving you the error, this will enable you to nail down to the exact line that is causing the error.
