The Stream class is an abstract base class, and derived classes may not represent a file (for example, MemoryStream represents an in-memory byte stream). In .NET, the FileStream class is usually used to deal with file I/O, so if the stream you're dealing with is based on a file, the Stream will likely be a FileStream instance. You can use FileStream.Name to get the original filename - for example:
string GetStreamFilename(Stream stream)
{
FileStream fs=stream as FileStream;
if(fs!=null)
return fs.Name;
return null;
}

I am writing an installer for my Paint.NET plugin. But it has two versions that work with different versions of the program. How can I programmatically determine the version the user is running so that the installer knows which plugin version to install?

Did you just said "Urgent" 
You should be very brave to mention this word here in the cp

It takes nerve to exclaim "urgent" on CP because people consider it extremely obnoxious. They take it as if you are demanding that someone help you, instead of asking politely.
Putting "Urgent!!!!!" into your subject line is the #1 way to get your post ignored. And that goes for most boards, not just CP.

Does anyone has any experience working with the System.ComponentModel.LicenseProviderAttribute framework?
More specifically, I am in the process of reviewing our licensing model, and came across this framework. Does anyone has any experience with this?
We are looking for the ability to keep track of flags and number of uses of certain features.
We would also like to allow our users to generate their own license keys, so some kind of web interface would be needed....
I'm looking into these options:
1. Writing our own custom framework
2. Using the LicenseProviderAttribute framework (if it will be feasible)
3. DeployLX (by XHEO)
4. Any idea you might have...

Hi
I don't know if it helps or not but in MS Word 2003 you can get the content of a word document as a xml document.
you can do it using doc.Content.get_Xml();
doc is a DocumentClass.
Later you can set the xml to another doc.

Hi All,
I have made a class named "node", in which i have declared 2 datamembers
1.string tableName.
2.ArrayList colNames.
then, I have declared another ArrayList named "Schema"and then add the node class object in that(Schema's class) list.
Now the problem is that I want to retrive the colNames from the Schema's class object separately, but i can't did.
Regards,

Hi
It seems that you want to get the value of some fields/properties of an object that is contained in a container object (an ArrayList for example)
If I'm right you can do it using one of the following methods:
1.whenever you want to access a member of an item of an array list cast it to its type:
<br />
((myClass)myArray[0]).MyProperty=some value;<br />
2.(.net 2.0 only)You can use generic container classes to define a type for you container object.This way all the member of the container class will be changed according to its type.For example when you write MyGenericList[0] it returns an object of the type you have defined for it
<br />
List<myclass> myList=new List<myclass>();
myList[0].MyProperty=some value;
in order to use a generic collection you should use System.Collection.Generics namespace

How is this possbile as I've been wrecking my brain over it for days....
how can I do it?

Hi
It's possible 
If you want to have some global variables that you can access from all of your forms you can implement them as static variables.
If you want to pass some info from some form to another here is my suggestion:
Have a constructor that accepts the variables as its arguments or you can have some properties for your form and pass the variables using them.Here's a better way that I suggest .Implement a context object that has the variables that you'd like to pass in it.then you can pass the context object between you form using one of the ways I mentioned.

Hi friends ...
I m facing problem in writing contents of BLOB field from database
to wordfile(.doc).
I used BinaryWriter for writing to the file. it works fine but when I
open the file in append mode and try to append the contents it do not works.
any sample code
thanking you ...

I'm afraid that appending information to a word document is not that easy to just open the file and append the contents to it.I think that you should use MS Word COM dlls to do such things.Using an Interop to MS Word dll you can almost do anything that you can do with word to a Doc file.For example you can save your information as a file and then insert it to the word document.
There most be a lot of articles about working MS Word using C# on the Net.

I'm using Npgsql to connect to postgresql in my dot net app. I create a new connection every time I need to perform a database operation. I store the username and password and if the user goes to another windows form, I pass the username and password to the constructor and then create another connection. This seems wrong to me. Is there a better way to do this? 
|
|
|
|
|
I think so; instantiate the connection once, open it and close it as needed, pass it around as needed.

Hi
Here's my suggestion
Have a DataHelper(or DataManager) class that is responsible to do DB management and other stuffs (like opening connections) make it singleton.
It can have a OpenConnection method that opens a new connection and returns it every time you want an open connection.For example
using(SqlDBConnection cnn=DataManager.Instance.OpenConnection())<br />
{<br />
cnn.Close()<br />
}

Oh I forgot that you were not using SQL Server.Then replace the SqlDbConnection with OleDbConnection.
|
|
|
|
|
It doesn't seem to bad to me. This is (in effect) the way that you would be working with the connections if you were working in a technology like ASP.NET. If the connection is pulled from the Connection Pool then you shouldn't have too many problems.
