TCP Client/Server communication: NetworkStream.Write() send partial data unless close() method is re

Hi to all,
I wrote a simple client-server application that comunicate through NetworkStream class. The problems comes when stream.close() and client.close() methods are called. It look like only the first 10415 bytes are sent once those methods are called. So, if the data to send is more than this size, it is automatically truncated.

If I  remove both stream/client close() methods from the code, the data is fully received whatever the size is. I tried various alternative solutions (the ones marked as comments in the sample code), but none of them works.
The only thing that seems to work is adding a manual delay before the close() methods execute with something like that:

For Counter as integer = 0 to 10

The problem is that after delay I still don't know if all the data has been transfered or not. In addition to that, I will have to wait 10 seconds before sending another request, even if the response is just a few bytes of data. I could change at runtime the number of seconds to wait according to the size of the data to send, but I still think that delay is not a solution and will cause adverse effects.

So, for now the only working solution is to remove both Stream/Client Close() methods from

Fax Services: Send Any Printable File From Your Program in Windows 2000


All versions of Windows 2000 have fax services built in, so sending faxes manually is as easy as setting fax options from the control panel. Faxes can also be sent programmatically in Windows 2000 using either COM Automation or the standard C API. The example in this article uses COM Automation with Visual Basic and MFC to programmatically manage faxing. The objects used for fax transmission, such as the FaxServer and FaxDoc objects, as well as their properties and methods, are explained. Because faxing of files you can't print can be problematic, this process is explained. Finally, this article implements a fax routing extension-a plug-in that exports standard functions and implements routing methods for processing received faxes.

Marshalling Your Data: Efficient Data Transfer Techniques Using COM and Windows 2000


The way you choose to transfer data is vitally important in a distributed application. Windows 2000 provides several new features that allow you to transfer data more efficiently. Lightweight handlers allow you to write smart proxies that can cache results and perform buffered reads and writes, minimizing the number of network calls. Windows 2000 also allows you to use pipe interfaces to transfer large amounts of data efficiently through a read-ahead facility. This article illustrates several ways to improve data transfer in Windows 2000 using these new features. It also reports the results of transfer time tests and provides recommendations for transferred buffer sizes.

OK button click on Windows dialogue form not triggering click event

I have created an Add-In for Outlook 2003 in Visual Studio 2005. When a new message is sent and a toggle button is selected, a form that I have created will be displayed as a dialogue box, where further information can be entered. Once this information has been entered you can click the OK button and the message is sent. If you were to click the OK button with invalid data in the form, there would be a message box with an error message. This all works perfectly on my development machine but when I have packaged the Add-In and installed it on other machines it does not work. Clicking on the OK button does nothing, there is not even an error message. All the prerequsits are successfully installed and this is the only part of the Add-In that does not work. All help greatly appreciated. Thanks Nick
