  Hi! I really don't know if this is the right place to post this question. . I have some confidential pdf statements (such as monthly statements from bank) on my window server (could on Novell directory also) and I will provide a download link in the web applicaiton for the web user so they can download or open the pdf file based on their login credential. the web client can not access those physical pdf files and only can download those files for themselves.

• .NET Development C# Asynchronous Socket. How to reject unwanted connection?

  Hi all, I am a newbie on C# socket programming. Can anyone teach me how to reject an unwanted connection based on the IP This is my code (it does capture that the IP is not the wanted IP, but then after rejecting this, the main socket won't listen anymore): Socket tempSocket = m_mainSocket.EndAccept(asyn); string cIP = ((IPEndPoint)tempSocket.RemoteEndPoint).Address.ToString(); // I want it to only accept connection from 202.103.212.32 if (cIP != "202.103.212.32") { tempSocket.Close(); Console.WriteLine("Rejected connection from " + cIP); m_mainSocket.BeginAccept(new AsyncCallback ( OnClientConnect ),null); } else { m_workerSocket[m_clientCount] = tempSocket; tempSocket.Close(); } Please help, as I've been ...Show All

• Visual Studio Express Editions Save collection into a file, then read back

  Hi folks, I have been doing some searching here about how to store the data in a collection into a file, to be able to read it back in later. I could save every data item one by one into a file, and then read it back one by one, but this is a painstaking and errorprone process. I found some articles about serialization/deserialization into an XML-file, but I cannot quite grasp it (yet). I am not sure if the serialization works with collections. Simply put this is what I want: (<<< is what I need to know>>>>) 1- create a (public) collection and fill it with all kinds of data 2- invoke a Save command, and obtain the filename and path to save to 3- <<< store entire collection into said file >> ...Show All

• Visual C# Property accessors - overriding one, adding the other

  Hi all, I ran into something odd today, and I feel like I must be missing something stupid because it seems so simple, but C# doesn't seem to give me a way to do it. I have an abstract base class with an abstract property with only a get accessor. Then, I have another class that derives from this base class.  In the derived class, I want to override the get accessor and I want to add a set accessor. I can't identify any way to do this.  Is it possible Thanks, Kevin James: Using "new" instead of "override" won't work here.  The compiler will complain that you haven't implemented the inherited abstract get accessor. Option B is a good suggestion in some situa ...Show All

• Windows Forms Bug in VS.NET 2003?

  Ok I had some time to make a sample project to demonstrate what I feel is a bug. Either that or I am doing something wrong here. http://www.myshack.net/fotty/VSBugSLN.zip Here is a link to a simple windows form app project and class library project (both part of same solution) Zip contains only the uncompiled project files. the class library contains 1 class which extends to textbox class (just makes the font red, this is just to illustrate the fact that its a class inheriting from a control) the windows forms app contains just 1 form, and references the class library project. Open the project, and compile it in debug mode prior to viewing form1. This is because the class library DLL needs to be compiled before it can be used on the fo ...Show All

• Visual Studio Need help: Graphical designer for my XML file

  Hi folks! I am a newby in this forum and this is my very first post. Our company develops a component-based framework based on .NET 2.0. For this framework, I'm currently working on a solution generator. The idea is simply that we create a processor which creates a complete VS solution from an input file which describes the application using xml. To manipulate this xml file, I want to create sort of a graphical designer (e.g. like the class designer in VS). Currently, we have only a simple TreeView to edit the xml which isn't very impressive... Thanks for your quick response! swisscklash79 Have a look at the Domain Specific Language support in VSIP (google it). It has a steep learning curve but it allows you to create designers ju ...Show All

• Visual C# Zebra TLP2844 USB Printing

  I've just taken delivery of this printer, and having worked with a mobile zebra printer recently, I figured it would be relatively simple. I'm having problems printing a label from within my application, and I get a PInvoke error when trying to use the RawPrintHandler class. Does anybody have any hints on how I print to it within my application I've created a print dialog and a print document, but all I seem to get is the actual text I'm trying to send it. I've tried EPL and CPCL, both just come out as text. I'm using Visual Studio 2005, I've installed the latest drivers and firmware from the Zebra site.

• Software Development for Windows Vista SHaring Data on PC and across the Local network

  So after about 30 setups my application actually installs on windows vista now. If you haven't tried to install a database on vista yet that can be shared amongst 2 or more users on the same machine you just haven't lived <g>. Its really fun! If you want a fun test, try to take a simple microsoft access database and install it on a windows vista machine so that 2 users can read and write to it. Despite days of work, hours of cussing and many posts on the msdn forums with other angry developers with this same issue, we actually managed to get this to work.
