.NET Development NetworkStream.Read don't get an exception
Hi. I'm developing a smal client-server application. Let's say that a client is connected to the server and is sending data. The server will read using NetworkStream.Read method. The connection dies. On the server side NetworkStream.Read will not get any exception. So, my question is: how can the server be aware that the connection has died Thanks. Mircea Hmm I have an answer but it may be false.But tcp/ip is packet swtiching protocol.So when data is available you send data or recieve data.when there is no data for sending ;it does not mean that client or connection dies.(like ip telephony).So you can ...Show All
Visual FoxPro function argument is invalid...
I have a problem with this message and a few similar once. When I get it I invoke the debugger and attempt to examine the variable/argument. In this particular case it is a memner of an array. I suspect that instead of a character string it got an .F. value but it is hard to prove because I cannot examine it. If I attempt to look at it in Command Window I will get the same message that it is invalid. More than that, some other related, neighbouring variables become shielded as well. If I try to examine them I get the same message. Is it a particular anomaly of my setup or a universal problem Can anything be done about it Thanks. Hi ...Show All

.NET Development Reading Offsets With in a File
Okay, I'm making an application to read AND edit certain offsets from a meta file extracted from a game. Okay so I have all the offsets, i just need to know how to get them to display in the textboxes. [code]Offsets: Velcity = 0x00 Velcity - To = 0x04 Variation Area - y = 0x08 Variation Area - p = 0x0C Local Variation Weight = 0x10 Local Variation Rate = 0x14 Damping = 0x18[/code] I'm not entirely sure what you mean, but I'm assuming that you want to get the values of the fields into the textboxes.

Visual Studio Express Editions invalid object
I am trying to write to a database table using native configuration. I have already checked my connection string, I believe I am connecting. However, I get the "table3 is invalid object " error. I checked the spelling and case of my objects. These objects exist. Why do I get this error Hi, from what i understand, if ExecuteNonQuery() is producing an error, then either the table name is wrong, the column name is wrong or there is a syntax error in some clause. use the following syntax.. string insertString = @"INSERT INTO table3(nodenames2) VALUES('"+ndeText+"')" ; im assuming that table name is table3 and column ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Welcome to the Performance forum!
Such a great idea! There has been a lot of concern about performance between Managed and Unmanaged DirectX applications, considering I'm both a C# and C++ developer, which language should I pick in order to start getting around the DirectX9 API I've been able to take a look to both DirectX9 versions and during the process I've been able to do a couple of small games composed by a single and simple 3D scenario, even though they're not fully productive at all considering they're just samples, they work pretty well, however perfomance concerns came up, and I can definitely see it's much faster to go on the .Net managed enviroment due to ...Show All
Windows Forms Binding a textbox or label on website
I know this is a "Windows Form" area but thought the answer might be simple.. In 2003 you could bind a text box or label to a DB and pick the actual field in the DB record to bind to. In 2005 the GUI doesn't seen to provide this. Instead under Data there's an Expressions field where you pick the bindable field (I choose Text), expression type (ConnectionStrings) but not sure what to enter for the Expression Properties. Any help would be appreciative. Thanks Please post this question here: http://forums.asp.net/ . Thanks, Joe Stegman The Windows Forms Team Microsoft Corp. This posting ...Show All

I cannot add File Attachment to Work Items. I get HTTP 500 Error. Please help Omar, What is the size of the attachment you are trying to upload Is it more than 4MB If yes: the problem could be that file size is larger then the maximum that is configured on the server. can you change the maxRequestLength property in the web.config (to configure the maximum upload file size). default is 4MB and it seems asp.net can handle a maximum of 1gig <Refer to this blog for more info> - Akhila ...Show All
