• .NET Development opening and reading text files

  I am new to visual c# and to programming in general. While I have taken a C++ class and have and understanding of if / else, while, for, do-while, etc., I have no clue when it comes to visual c#. Does anyone have a simple application that opens a text file (where the file name and location is entered on the form) and reads the file. Anything close would be appreciated. Ultimately I need to have an application that reads the text file, line by line, and compares it with a string that will also be entered on the form. Thanks! Here's something you need to learn about the C# paradigm early on: it is very different from C++, despite the similar syntax. Your question is a perfect example of this. In C++, here's a typical way to read ...Show All

• Visual Studio Team System HowTo: Export a database to a script

  I'm running CTP5 as of this morning.... My coworker asked me how someone could export a database to a script. So I've spent some time looking around, but I haven't found a way to do it yet. I see how I can import a script but no export. Is is possible to export a table or db to a script which I could then at a later time import onto another SS2005 box Please let me know if you need more details, I'm new to VS 2005 Team Edition for DB pros. thanks. Steve Mayhugh MCSE, MCDBA, MCSA You can use the data compare tool to generate a script of the data. To do this, use data compare to compare a version of the database w/ data (source) to a version of the db w/o data (target). You will then be able to create a synchronization ...Show All

• Visual C++ C++/C# InterOp and gacutil/regasm

  Hello everybody, I am getting in the tough issue in my application. I hope I can get some advice from you. My application CatchAllMessages is mainly written in C++ and is used to catch messages from the internal network. I have many interfaces to display message data. But for some unlucky reason, we designed the new interface written in C# to catch a new message which has the different platform compared to messages caught in CatchAllMessages application. That's why I am using Interop to regsiter the C# DLL as the COM object. What I did was to create the DataWrapper.cpp class( in DataWrapper project ) which translates some basic data of the message, such as IPAddress and the content of the message. Then, I created the NewMessage. ...Show All

  Hello folks, I have just installed vista and the next step is to install other software for developing applications on vista. While trying to install SQL 2005 i get an error message which says that i dont have enough previleges to use IIS.

• .NET Development Trying to make Socket object be accessible in many threads

  I'm trying to compile a variant of the Server and Client example programs from the book "Visual C# 2005: How to Program, Second Edition". Basically, (my variant of) the program is a form that allows the user to be either server, or client, of a very simple chat program. I'm practicing the TCP protocol in C# programs, so I'm limiting myself to text network streams. In Server mode, you can (before a connection is attempted): -modify the port -Start listening In Client mode, you can (before a connection is attempted): -modify the port -modify the target IP address -start connection attempt In server mode, while connecting, a new thread is launched and will do these things: -create and construct a TcpListener object, then call its Start() meth ...Show All

• Visual Studio 2008 (Pre-release) Drag and Drop - How to interchange Tab Item positions

  Is it possible to re-arrange tab items on a tab control using drag and drop assuming that the TabControl sits on a standard container such as a Grid Appreciate anyone's inputs on this. Can I not use the native drag-drop event handlers, properties provided by WPF against most controls such as DragEnter, DragLeave, DragOver, AllowDrop=True, GiveFeedback etc. I did try using these and against each event handler, put in some dummy code (in this case populate a textbox, just to test if the events fire) - but for some reason, none of the events appeared to fire. I am using Grid as the base container to host the controls on which I want to carry out drag-drop- is it required that for Drag-Drop events to fire, the ...Show All
