here is my code
CRAXDRT.Application crxApp = new CRAXDRT.Application();
CRAXDRT.Report crxRpt = new CRAXDRT.Report();
crxRpt = crxApp.OpenReport(@Application.StartupPath+"\\Report_1.RPT",null);
string myExportFile = Application.StartupPath+"\\Report.txt";
crxRpt.ExportOptions.DiskFileName = myExportFile;
crxRpt.ExportOptions.FormatType = CRAXDRT.CRExportFormatType.crEFTText;
crxRpt.ExportOptions.DestinationType = CRAXDRT.CRExportDestinationType.crEDTDiskFile;
crxRpt.ExportOptions.RTFExportAllPages = true;
crxRpt.Export(false);
after i export, i want to close the crxRPT and crxApp object.
because i want to copy the latest database from the server to the my PC but i can't because these object are still connected to the database
i try this but didn't work.
crxRpt = null;
crxApp = null;

Can anyone give me any guidance on how to store details from a windows form, entered via user input, into an XML file and then display those details to a DataGrid in the form of a table?
Also, how do I populate a drop down menu with a list from an XML file?

Btw, the code below was typed directly into this textbox.. it is prone to have syntax/compilation errors!
<br />
XmlDocument xd = new XmlDocument();<br />
xd.Load("c:\\myxml.xml");<br />
foreach (XmlNode xn in xd.SelectNodes("/Root/Item"))<br />
{<br />
myForm.myCombo1.Items.Add(xn.SelectSingleNode("@ItemNumber").InnerText);<br />
}<br />
To store user values in Xml document you may use XmlTextWriter
XmlTextWriter xtw = new XmlTextWriter("c:\\output.xml");<br />
xtw.WriteStartDocument();<br />
xtw.WriteStartElement("MyRoot");<br />
xtw.WriteAttributeString("UserName", myForm.textBox1.text);<br />
xtw.WriteEndElement();<br />
xtw.WriteEndDocument();<br />
xtw.Close();

hi
Basically i am creating one windows application which will hook some functions in the dlls. i want to log the events that are happened in both dll's and the windows form into some log file(events like the cmds processed in the dll functions or action happened in the windows form(like clicking)).
I have tried EventLogger but it is using the system application log. I want to log the events in specified text file.
so i tried directly writing to the file but this cause Locking problem ie. when one dll is writing entry simultaneously if another one trying wirte an entry cause an exception (file locked by some application).
so iam thinging of going for MSMQ, I thing most of people have this kind of Event logging mechanism how they are doing this. could u please helpme to sort out this problem

Use System.Diagnostics.Trace class and create your own TraceListner. .Net already provides with a built in class for such purpose: TextWriterTraceListener:TraceListner.
The log4net is also a good library.

Thanks for ur reply,
I have tried the TextWriterTraceListener class to write the trace msgs into a file, will there be any locking problem if multiple dlls or exe try to write into a file at the same time??
i tried with 3 threads writing at the same time it seems to be like all the message from 3 thread getting mixed and written into the file??
is it correct to use tracelistners for event logging ?? since our event log file is very important we used it in the manufacturing station?? so there should not be any missing data..
Any other way to do this..
Thanks in Advance

From my recollection, the textwriter uses stream in the base and flushes the stream as needed. So you're not always opening and closing the file everytime to write something to trace. From my past experience, I did not run into this problem.
Is the fvent logging is for debugging purpose? if so, do not pollute the System Event (App.) Log. The Event Log does have a limit on the size and throws you a nasty exception if the rate at which you're inserting the new entries is greater than the rate at which it can process deletion of old entries. And the worse part is that there is no information in the Exception which points you to the actual source of the problem.

Hello,
If the user2 is logged in onto the machine, and trying to log into a SQL Server that using Windows-Credentials Logon, can the user2 impersonate user1's credentials to log into SQL Server? Assuming that user1 has windows logon.
Thank you
Help will be greatly appreciated.

That sounds pretty illegal to me, so i doubt MS put functions specifically in .NET to flaw their own security..
What exactly do you need it for?
|
|
|
|
|
I just want to have one account that would be able to access SQL Server. Application that is run by numerous users (Which will not have access to SQL Server) will pull the user information from lets say Windows Registry and use that information to access SQL Server.
Thank you

Why not create a SQL logon and only allow them access to the database that you want.
We have a config file that resides in the same path as the app that tells us who they should logon as, the database, and the SQL server name.

I really did not want to use the Mixed mode to log into SQL Server. But integrated Security.
Thank you

Integrated Security doesn't support login's like you want. It only supports using the Windows Identity established on the O/S thread when you logged into Windows. You can't use alternate credentials with Integrated Security.

Thanks
I figured that, since when you select Windows Credentials login to the SQL Server it never prompts you to use the credential settings.

hallo 
how do I divide the computing of a selected program between two computers.
for example, i am using word though my computer computing half of the program.
can somebody help my?
thanks.

What you're refering to in your example is not clustering. The application has to be written to support what your talking about. You can't just open Word and expect two machines to run the same instance of the app. There is considerable low-level O/S and hardware support required to get something like this to work.
This is something that is FAR beyond the capabilities of the .NET Framework.

Hi,
This is what I have which is assigned to a string variable. I would like to replace the \\ to \
How is this done please?
I tried:
string strData = strData.Replace("\\", @"\")
But it does not work.
Thanks
strData = "{\\rtf1\\ansi\\ansicpg1252\\uc1\\deff0{\\fonttbl\r\n{\\f0\\fswiss\\fcharset0\\fprq2 Arial;}\r\n{\\f1\\froman\\fcharset2\\fprq2 Symbol;}}\r\n{\\colortbl;\\red0\\green0\\blue0;\\red255\\green255\\blue255;}\r\n{\\stylesheet{\\s0\\itap0\\f0\\fs24 [Normal];}{\\*\\cs10\\additive Default Paragraph Font;}}\r\n{\\*\\generator TX_RTF32 12.0.500.501;}\r\n\\deftab1134\\paperw12240\\paperh15840\\margl1440\\margt1440\\margr1440\\margb1440\\pard\\itap0\\plain\\f0\\fs24 is is\\plain\\f0\\fs20 to \\plain\\f0\\fs20\\i confirm\\plain\\f0\\fs20\\par for \\plain\\f0\\fs20\\ul testing\\plain\\f0\\fs20\\b reasons...\\par }"

string strData = strData.Replace(@"\\", @"\")
or
string strData = strData.Replace("\\\\", "\\")

C# reads "\\" as one slash, so type "\\\\" instead

I think that you should look at the real problem, not just the symptom.
Why do you have a string that contains double backslashes? Where does the string come from?
I see that you also have escape codes like \r and \n in the string. If you don't handle them first, you will end up with a string that contains some "\r" that means Carrege Return, and some that doesn't.

Looks like an RTF file header.

Yes, I recognise the rtf code, but that is not the point. Where does the string come from, as it contains escaped characters? If it would have been read from an rtf file, it woudln't.

Why does this matter? You can have a hardcoded rtf string somewhere to preset the contents of a RichTextBox for example, and the sample the original author gave here looks just like such a case.
Besides it seems to be perfectly good rtf, he just misinterpreted the escaped backslashes...

I agree.
What does it matter where the string came from?
He simply wanted to know how to fix the string by replacing the double backslashes with singles. Problem was solved.
