I did mention to debug your code and try it out. Were you not calling the EndMethod event before? Using either callbacks or the EndMethod - if you care about any returns values, exceptions, etc. - is necessary. Otherwise you're just aysnchronously invoking a method and won't get a return back. For methods like logging methods, this may not matter but for methods like Add(int, int) you would certainly want the return value back.

If the web service throws an exception, the End* methods will throw it, and you can handle it there.
Yes, even I am blogging now!

Thanks, wasn't aware of this fact. Sounds like the correct place to catch those exceptions so that is what I'm gonna do.

Heyas all,
I'm kinda of stuck here and was hoping for some feedback and opinions. I'm attempting to design a simple CD cataloging programming in C#, the easiest part of designing the form is done. I'm trying to determine how to store the information such as "program name" "publisher" "cd number" "date added". I have MSDE installed and running however I've been reading and it seems that MSDE is used to program the connectivity to the database that will eventually be run on a computer with SQL server installed. I don't think this is what I want. I'm looking for something that is built into the program, you could import an existing database, export etc. I don't want the users to have to rely on having a 3rd party application installed (i.e. SQL server) Can anyone point me in the correct direction maybe someone knows of some links to beginners type Data stuff pertinent to what I want to do? Maybe this post should even be in the ADO forums, if so I appologize. Any information would be great.
Thanks All!

I think MSDE is actually a good solution for what you are trying to do. While there are "compiled-in" database libraries available, I have not seen any for .Net or that are written in managed code. MSDE is free and relatively easy to install and configure and is compatible with SQL Server. In fact the database engine IS Sql Server with limitations imposed on the number of concurrent connections and the maximum database size (4 Gig I think). The should be more than sufficient for a CD catalog program.
Just my 2 cents... Have fun.

In the same situation, I've used in-memory DataTable class of .NET, and saved information on disk in raw text format. (text files with tab as column delimiter).
It was enough for me - my application is not always running and do not need very fast search, sort etc. features. Try this out, may be it'll be enough for you too...
And, one more thing, when my databases becomes too big - I've added zip engine. So, database is saved, then zipped on disk. And, when loading, unzipping and loading.
Hope it'll help...

Hi, I'm implementing a custom business object collection and must implement IBindingListView.Filter. It appears that it must parse a string which contains an expression (a la DataColumn.Expression) that evaluates to a boolean value and determines whether the object is to be filtered out. I am comfortable working with all of the binding plumbing... PropertyDescriptors and such. However, I have never implemented any sort of expression language before. If any one could spare half a clue on where to start researching this, I would be most appreciative.

Why not look to see how DataColumn.Expression works? You can use ildasm.exe that ships with the .NET Framework SDK (also installed by default with VS.NET) if you know how to read Intermediate Language, or use a decompiler like .NET Reflector[^].
This can be a great way to learn how things work internally in the BCL, which may lead to cleaner code that you can write, as well as new ways to use or extend the BCL types.

I have a website with 3 frameset. I need to know how do I code the linkbutton_click event to open another page but in another frameset.

Any help would be appreciated

Hi,
I need to create a file and the data I am writing to it needs to be in the following format.
"CAT",2,13.0,"X"
How can I write out the data so that some of it is quoted and some of it is not?
Also, I have a non quoted file which i write using Stream Writer and it works fine. I have noticed that Stream Writer automatically puts a new line at the end of the file. How can I remove this line or control when the file writes a new line?
Thanks in advance.

Have you tried backslash befor quotes?
something like this:
string towrite = "\"CAT\",2,13.0,\"X\"";
and for and-of-line symbol - are you using WriteLine() method? Try to use Write() method instead.

As far as i know - u can add nodes until u run out of resources.

Why should a treeview has max number? I think it doesn`t have it.

Hello!
Does anybody know how to insert text into bookmarks in Word using late binding? If I use early binding everything works fine.
What I want to implement is somthing like this:
for (int i = 1; i <= document.Bookmarks.Count; i++)
{
object objI = i;
document.Bookmarks.get_Item(ref objI).Range.Text = "Some text";
}
but using late binding instead.

Hi
I use OleDb to access MSAccess database, allways successfuly with out password, but when I set database password from Access (menu-> Tools-> security-> Set Access Password )it fails to connect even if i use the same password in the connection string such as:
conStr = "Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;password=<thepassword>;Data Source="+ DataDir + DataBaseName + .....
the error message is [cannot start your application. The workgroup information file is missing or opened exclusively by another user.]
is there any way to set a pass word for a data base so it can not be opened from access and available from the application please?

In Javascript, I used this method to open a browser: window.open(URL) but I dont know how to use this way to open a new window in C# (Im writing a web page using ASP.NET with C#). Can u tell me about this?
Thank you in-advance!
|

You still have to use your javascript code, cause ASP.NET is a server-side technology and therefor cannot provide a functionality like window.open.
