Hi all
I am serializing an object to memory stream using XmlSerializer. My problem is after serializing the whitespace values of properties in the objects are converted to null in the memory stream. Is there any way I preserve the the whitespace values during serialization.
Thanx & Best Regards

Hi all,
I have a queston on code obfuscation in C# as follow,
If the code contain string, say
String a = "apple";
Will the "apple" be also obsfucated into another string by the obsfucator ?
Thanks

Not really, otherwise you would lose the string information. I suggest to use a database, which holds the original string and is called by an own module ( as used in multilanguage applications ).

Hello C#-Comunity!
I have a little problem using Reflection under C#.
I defined an abstract class with a static method in an assembly '.dll'-file.
In source code it looks like:
<br />
<br />
public abstract class MyClass<br />
{<br />
<br />
<br />
public static int MyStaticMethod(int paraNumber)<br />
{<br />
}<br />
<br />
}<br />
<br />
This code is compiled as a '.dll' file. Then it´s not implemented via Reference in Visual Studio, but as an reflection-load with the
'System.Reflection.Assembly.LoadFile(...)' - statement.
My problem is to invoke the static method in this abstract class via reflection.
With the statements:
<br />
<br />
Type MyMetaObject = assembly.GetType("MyClass", true, true);<br />
<br />
object[] parameters = new object[1];<br />
parameters[0] = (object) paraNumber;<br />
<br />
object retObject = MyClass.("MyStaticMethod", System.Reflection.BindingFlags.InvokeMethod, null, ?X?, parameters);<br />
<br />
This doesn´t work 
I think the problem is the '?X?', because I tried it with 'null', but it causes a runtime error like 'Object reference is not set to an instance of object' [or something like that].
Normally the '?X?' parameter is for an instance of the object which method will be invoked, but I can´t create an instance from an abstract class object!
Has anybody some solution proposals?
Thanx for any help!
Ciao

1. You cant use reflection directly on the class. In fact the compiler shouldnt even compile such code... 
2. Your bindingflags are wrong. Try a combo of Static and Public.
3. DONT ever skip steps with reflection. It will save you time figuring out what is wrong.
Eg
Type t = typeof(MyClass);
MethodInfo mi = t.GetMethod("MyStaticMethod", bindingflags);
object ret = mi.Invoke(null, params);

Hi leppie!
Sorry! I forgot the InvokeMember statement
It should be:
<br />
object retObject = MyClass.InvokeMember("MyStaticMethod", System.Reflection.BindingFlags.InvokeMethod, null, ?X?, parameters);<br />
And why should this not work?
Ok I tried with both Flags, but ths won´t work, too!
But my error was much more simple, I detected that my MyClass was 'null' because I forgot the namespace to find my 'MyClass' --> 'Namespace.MyClass'.
But why he didn´t throw an error, I don´t know!
Thx therefore Leppie, explain why I should make it with your solution? Is it faster?
Ciao

Modems don't offer support for this, so hardware-wise, this isn't going to happen. You can't catch the number that is dialed by the phone.

The phone system exports this data! In the last 3 jobs I had, the phone system was connected to the network, just like any other workstation.

There is an article,
http://www.codeproject.com/vb/net/Wordyna.asp
which is very useful, and I am very happily exporting web pages to word documents, with a little help from
TextWriter textWriter = new StringWriter();
Server.Execute("something.aspx", textWriter);
Response.Output.Write(textWriter.ToString());
as well, where I can excute any aspx and get the resulting output, do anything i want with it, and redirect to a word doc.
Does anyone know how to save this stream to a PDF, without getting a third party control, or using crystal reports?
Thanks

Get a third party control. Unless you want to go through the hassle of writing your own .PDF generator... Do you know anything about the format of a PDF file?
The easiest way to do it to search the web for a free PDF Printer driver. Then all you do is print to that "printer" and it will generate the .PDF file for you.

thanks. the PDF generator looks real good, the next question would be, how would I bundle it with the MSI i create to distribute the web application... it won't be very helpful if I have to distribute it seperately. thanks again, the alientools PDF Generator is pretty good.

You'll have to get with the author(s) for any licensing permissions and distribution issues.

Where to put some(about 300) certain strings(the list exists forever and I am not going to insert or remove any string) to find out quickly if a new string is among them?
SortedList, ArrayList, Stack, switch() or something else?
