as System.Boolean.True hasn't been provided, do you also type System.Boolean.Parse(System.Boolean.TrueString) instead of true?

Don't tempt me; every once in a while I think about not using any of the aliases at all (they're all just syntactic sugar after all). Unfortunately they're required to specify base types for Enumerations  .

I have great news for you:
System.String
System.String
System.String
The second one has "lang=none" in the CODE tag.

Cool, is stuff like that documented somewhere? (am I just bad at searching?)

I trust it is, however for harmless things like that, I just experiment a bit.
I always allow for a few minutes of heuristics before taking the scientific route.

Yes, Chris enlightened me about that a day or two ago. I still say that text should be the default.

look over this file and tell me how are you thinking in improve it !
I spend an entire night at it.
The idea is to have a MAP (on the paper) and rapidly look over it and "remember" what i must to put when I need it.
it's like a pocket reminder(a very tiny little map).

of course in time must be the answer....if any...hope so...
thanks again.

I'm pretty sure the only reason they have a the String class is because Java has a String class.

I Am Checking with System.IO.Directory.Exsist(), however it will return false either if path doesn't exsist or syntax is incorrect.
How can i detect if syntax is correct

What do you mean if syntax is incorrect? Can you give an example?

Hi,
I haven't tried this yet, however I expect new DirectoryInfo(path) would throw an exception when it doesn't like your path.

Hi all,
Sometime ago I wrote some automation tool to get content of some site.
Everything worked fine untill one day...
My C# code creted url string and made http hit. I used HttpRequest and Response.
Request looked like http://somesite.con/param1=a¶m2=b¶m3=c
Now, there was a change in the site and it always makes redirect to the url that looks like:
http://somesite.con/param1=a¶m2=b¶m3=c&rnd=AbCdEfG1.
With the fiddler I saw that actially web browser makes 2 hits:
1. The old one.
2. The new one.
Now the response of the first hit contains some JS code that generates this random code (AbCdEfG1), concatinates it to the main url and makes redirect.
As far as I understand I need to execute this JS from C#. It's may be done in the several ways and seems not too complex to do.
But then I need to or:
a. get back this random value from JS.
b. allow to JS to make redirection, but need to get back the response.
I prefer the b. because code that generates this random value always different (code generation or something).
The code of JS is something like that:
html>
<head>
<title></title>
</head>
<script type="text/javascript">
function redirect()
{
var redirectLoc = window.location.href;
if (redirectLoc.indexOf ('?')>-1) redirectLoc +="&"; else redirectLoc+="?";
redirectLoc = redirectLoc.replace (/rnd=[0-9a-zA-Z]+&/,"");
window.location = redirectLoc+'rnd='+f1();
}
</script>
<script type="text/javascript">
function sbbpWvum()
{
nCc = typeof "zCa";
return String.fromCharCode(nCc.charCodeAt(4)^37);
}
function f1()
{
return sbbpWvum();
}
Any one can help with this isue?
Thanks.

What is best solution for logging app data when crashed.
Is it possible to log data into xml or other formats a unhandled expections, where the data woud specify file, line and possibly a dump
|

If you use Vista, then you can use its Application Recovery to recover from a crash. There's an article on CP for it here: Vista Application Crash Recovery in C#[^]
If you're going to save data, then I would make it as simple as possible. If you've got the Exception object, then the stack trace, exception type name and exception message would be a good start. You'd also want to get that for the InnerException, if it's not null. For the purposes of error logging, I'd just serialisation. It's still easily emailable, can be saved into XML format, and will have the data you need. And there's very little which can go wrong with it, so you're highly unlikely to get an exception, which would trigger the exception handler, which would raise an exception, which would trigger the exception handler ad infinitum.
Obviously if your application handles secure data, then you've got to save it in encrypted format. This can still use serialisation; you just need to save it to a CryptoStream instead of a FileStream

all,
I had an application that could access an mdb file via OleDb (Provider=Microsoft.Jet.OLEDB.4.0).
I received a new machine now, which is an x64 and it stopped working. It only works if I open up the solution and press F5 (doesn't matter if it is release or debug). So I did some searching and changed the provider (Provider=Microsoft.ACE.OLEDB.12.0) which works the same as above and also used a target x86 platform to build the application (I read x64 wasn't supported). Same behaviour. double clicking the exe fails to open the database, pressing F5 works without problems.
Here's the error:
Error: Could not connect to database: Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\vmalisse\Desktop\astrid_v21_result.mdb;User Id=admin;Password=;.<br />
error: The type initializer for 'System.Transactions.Diagnostics.DiagnosticTrace' threw an exception.
Can anyone point me to the problem? I'm not quite sure what exactly is wrong.
thanks.

According to MSDN forums your app might have configuration problem.
Life is a stage and we are all actors!

Thank you very much for the reply, apparently as you said, there is a configuration problem. I needed to ADD an App.config to my application. It's empty, but that did the trick.

Hi,
my app logs correctly while code is beeing executed within my method DoIt. But it doesn't log in the Process.OutputDataReceived's EventHandler even if p_OutputDataReceived is called.
Is there anything I need to look at while using Process?
private void DoIt(string arguments)
{
_log.Fatal("TEST");
Process p = new Process();
p.StartInfo.FileName = @"D:\vssTOOLS\NetJobs\UpdateDealArchiveInstrSeq\UpdateCaller\bin\Debug\UpdateDealArchiveInstrSeq.exe";
p.StartInfo.RedirectStandardError = true;
p.StartInfo.RedirectStandardOutput = true;
p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
p.ErrorDataReceived += new DataReceivedEventHandler(p_ErrorDataReceived);
p.StartInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetAssembly(typeof(Caller)).Location);
p.StartInfo.UseShellExecute = false;
p.StartInfo.Arguments = arguments;
p.Start();
p.BeginOutputReadLine();
p.BeginErrorReadLine();
p.WaitForExit();
do
{
System.Threading.Thread.Sleep(100);
} while (!p.HasExited);
if (p.ExitCode != 0)
{
for (int i = 0; i < procOut.ToString().Length; i += 2000)
_log.Info(procOut.ToString().Length > i + 2000 ? procOut.ToString().Substring(i, 2000) : procOut.ToString().Substring(i));
for (int i = 0; i < procErr.ToString().Length; i += 2000)
_log.Error(procErr.ToString().Length > i + 2000 ? procErr.ToString().Substring(i, 2000) : procErr.ToString().Substring(i));
throw new ApplicationException("Es ist ein Fehler aufgetreten: " + procErr.ToString());
}
}
StringBuilder procOut = new StringBuilder();
StringBuilder procErr = new StringBuilder();
void p_ErrorDataReceived(object sender, DataReceivedEventArgs e)
{
procErr.AppendLine(e.Data);
_log.Error(e.Data);
}
void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
procOut.AppendLine(e.Data);
_log.Info(e.Data);
}

Hi,
I am using a procedure which selects some rows and handles a output parameter.
I am executing this procedure using SqlDataReader.
Problem Is ,
If Connection is kept open after ExecuteReader(), Sql Reader is working fine and able to do data binding. But, output parameter is returing null value.
If Connection is closed, I am able to get the correct output parameter value. But, SqlDataReader is not working.
Any Ideas to make both working regardless of connection status.
Thanks,
Nagaraj

You can't. You only get the ouput parameter back when you close the connection. Its always been that way.

Thanks Bob,
My code is fetching the records for GridView Binding (for the selected PageIndex) and total results in single call to database.
I am returing SqlReader from DAC to BusinessLayer and to Code file from there.
Is there any better way to achive this?
Thanks again
Nagaraj
