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.

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

An app in .NET 2 with WPF Rendering?

Manaxter5-Mar-07 21:01

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.

to ping /poll the SMTP server before hitting

If I forget to load OL Express, it dies.. Frown | :(

Isn't: System.Net.Mail.SmtpClient("svr")
supposed to return a value? Cry | :((

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.

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?

thanks in advance

I am not sure how to do a post build event for debug builds only, but I am guessing that the reason you want to do this might be to set certain configuration settings for your application.

I just wrote an article about how to control different setting for different configurations, debug (dev), test and prod.

This solution is only for .net 2.0 so I don't know if you are using .net 2.0 or not. I also don't know if this is your issue. Anyway, here is the link:

Is WPF fast enough for real time?

I had written a real time semi-automatic option trading platform in C# using Forms for GUI (and native C++ for math...).

Can anyone say if a WPF porting will make the program less responsive / more sluggish? This is supposed to be real-time so every millisecond counts.

Only your testing can determine that. You can see a huge performance swing depending on how you've written your code.

I think it will mostly depend on how the application is written. Keep in mind that WPF is a vector based display technology, but it shouldn't have a problem.

The better option will probably be to rewrite the application to take advantage of WPF and the data binding capabilities rather than to just port it. WPF is a completely new beast and there are better/different ways to do things than we had in WinForms.

Hi all,
I am making simple screen capture win32 application using VC++.NET. I am able to capture it in the memory and getting handle of that bitmap but I am not able to show that bitmap in Picture Control in dialog box. Can I know what wrong with my code??
I am pasting my code here.

int nScreenWidth = GetSystemMetrics(SM_CXSCREEN);
int nScreenHeight = GetSystemMetrics(SM_CYSCREEN);
HWND hDesktopWnd = GetDesktopWindow();
HDC hDesktopDC = GetDC(hDesktopWnd);
HDC hCaptureDC = CreateCompatibleDC(hDesktopDC);

HBITMAP hCaptureBitmap =CreateCompatibleBitmap(hDesktopDC, 
				nScreenWidth, nScreenHeight);

SelectObject(hCaptureDC,hCaptureBitmap); 

BitBlt(hCaptureDC,0,0,nScreenWidth,nScreenHeight,hDesktopDC,0,0,SRCCOPY|CAPTUREBLT); 

::SendMessage(::GetDlgItem(hDlg, IDC_BITMAP_CONTROL), STM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hCaptureBitmap);
		
ReleaseDC(hDesktopWnd,hDesktopDC);
DeleteDC(hCaptureDC);
DeleteObject(hCaptureBitmap);

Thanks,
Priyank
