No I’m not calling from an event but there are several timer procs in the main MFC software.
I have totally abandoned the DoEvent method. It causes to much strange stuff.
Now I have to keep my webbrowser control going. I need it to paint the info.
Thanks for thring to help

I'm using serialization of objects for a client-server application, these need to communicate and I want them to send and receive a message (ApiMessage) that contains a base class NetworkElement. There are several types of network elements that derive from this base class.
[serializable]
class NetworkElement
{
}
[serializable]
class NetworkElementX: NetworkElement
{
}
[serializable]
[XmlInclude(__typeof(NetworkElement))
class ApiMessage
{
NetworkElement* pNetworkElement
}
When I fill my message with a NetworkElementX and serialize an exception is thrown, the inner exception mentions that class NetworkElementX is not expected and I should use a XmlInclude arghhhh
The technology is great and works in cases when I use an ArrayList to transport objects. I shall try and encapsulate my object in an ArrayList and see if that works.
I've tried all sorts and been going around in circles for ages, if anyone has any pointers  it'd be much appreciated.

hi priya
i have got complete payroll source code if you want it send mail or
IM in yahoo my yahoo id is nare700
my emails nare700@yahoo.com
nare700@gmail.com
I have read the previous posting in this forum. In it, it mentioned the use of dataset to achieve this.
I create a dataset which one of the field in the data table is base64binary.
After retrieval of the file path, open the file and store the image file as array of byte in that column.
When you bind the dataset to your report as the data source, you can easily drag and drop the image field to your report.
Conversion of image file to array of byte:
Dim fs As New System.IO.FileStream(<file path="">, IO.FileMode.Open)
Dim br As New System.IO.BinaryReader(fs)
Dim arrayByte() As Byte
arrayByte = br.ReadBytes(CInt(fs.Length))
br.Close()
fs.Close()
Hope this help!

I think I know the answer to this, but here goes.
I have developed an app using .NET 2.0 Framework, and now have a potential customer wanting to run it on Windows NT. I have trawled the web for the last 2 nights, all leading me to the same conclusion; .NET 2.0 cannot be installed on WIn NT. Could someone please confirm or deny this for me please. 
Thanks in advance

All you had to do was search MSDN for ".NET Framework System Requirements" and you would have had it in 10 seconds.
System Requirements for Version 2.0[^]
You are correct, NT4 is not supported.

I had found that info, but the post was a last chance; just in case.

OK. I don't know what was so ambiguous about the part of the that page that said "The .NET Framework cannot be installed on the following operating systems...", but, OK....
Wait 'til the .NET Framework 4.0 comes out and Windows 2000 won't be supported.

The only possibility I can think of is one of the commerical programs that compiles .net into a native executable. If your app isn't actually calling any post win2k APIs one might work.

Yeah, but what about the classes in the .NET Framework that would be calling post-NT API's?

It would depend on what all he's using from the 2.0 framework, which was why had the disclaimer. Some stuff like generics I assume should be OS independent.

This article would have you use a wrapper class that serializes more nicely than DataSet, and in fact it really does halve the size of the dataset (in serialized form).
However, the time it takes to serialize a decently sized dataset 100 times to the time it takes to serialize the surrogate 100 times is 6 seconds to 30...
Nonetheless it seems like the overall consensus is that it's good to avoid sending DataSets across remoting and soap.
What are your thoughts and solutions on the matter?

I ran into something like this a while back. We had large files that we needed to send across a web service. I wrote an article on the solution I came up with:
http://www.codeproject.com/cs/webservices/sending_files_via_webserv.asp[^]
Note if you do have a web service some of the new WSE 3.0 allow some pretty nice features for attaching files. It means that WSE 3.0 needs to be installed, but some nice stuff comes with it.
Anyway, my article is about files, but you can certainly take other large objects and zip them down and encode them and pass them along a cdata node.
Anyway, I don't know if that will help you out or not.

Thanks for your response. I looked at your solution and it may work well enough for files, but in serialization and compression it's really the file type that matters. You created a pseudo-schema, which is almost like a dataset in itself.
I'm just trying to find the quickest way to do it. The problem with the Surrogate that MSDN suggests is the large overhead to get to it.
A simple object[][] (light but a pain to use) outperforms DataSet and DataSurrogate (zipped and unzipped) significantly on a small number of rows, but as the actual size increases, the difference fades.

If there are multiple projects in a single solution, then how to access a function from one project in another project.

You can add a reference in the caller project.
Right click references, click projects ,select the project that contains the class.
make the class and the function public

Hi guys.
I want to write my program in .NET 2.0, just because I'm used to it (and because it will be primarily run on XP). However, for a certain part of the screen (i.e. a separate window) I want to use WPF to render text and video etc. Is this possible? What I was thinking was creating a component in WPF, and adding it to my app. Does anyone know of an easy way to do this? Am I just confused, thinking that I cant use .NET 2 controls in a .NET 3 project?
Any help would be appreciated.
Cheers
Jacob.

The CLR and Windows Forms are completely unchanged in ".NET 3.0". I put the quotes round it because ".NET 3.0" is a stupid marketing name for .NET 2.0 plus WPF, WCF, Workflow Foundation.
I believe there are components which allow WPF to render to part of a Windows Forms form, and to put Windows Forms controls on a WPF-managed window.

Anybody know right off the top of their head how
to ping /poll the SMTP server before hitting
email.send("","","","") without resorting to:
Try
Catch
Finally...?
If I forget to load OL Express, it dies..
Isn't: System.Net.Mail.SmtpClient("svr")
supposed to return a value?
Thanks,
B.Griffin

No, SmtpClient is a class, not a method. Perhaps you were thinking of the SmtpClient.Send() method? But it also doesn't return a value. If something goes wrong, it will only throw one of six exceptions, documented here[^].

You can ping the target server, but there is nothing that says that the target server has to respond to that ping. It's also entirely possible that the target is sitting behind a firewall, blocking ICMP Echo requests, thereby neutering your attempt to "test" the server's presence.
Basically, you can try to ping the server, but it's no guarantee that the server is, or isn't, actually there and responding. The only thing you can do is try to send the message and see what happens.

Dave:
Thank you sir.
I only searched the CodeProject DB before asking.
I'll check MSDN too, next time. Heaven knows I
pay enough for it!..

Hi,
first of all, i don't know if i'm in the right forum, beacause
the topic is "base classes" of .NET and TeamFoundation is an
additional SDK, so please excuse me if i'm wrong here.
so now my question.
is it possible to serialize an TeamFoundation WorkItem?
i've tried XML, not working
binary serialization, not working, too.
so does anybody know how i can serialize this?
greetz pdluke
thanks in advance
