• Visual Studio Express Editions Query Problem

  I work for an electric company and I am trying to create a simple windows application that a user can input: 1. Substation Number (2 digit number) 2. Circuit Number (1 digit number) 3. Number of Pole numbers needed I have a SQL database table that has an ID column and a Pole number column and it is populated with our current pole numbers. I have created a query that will get the last pole number for the sub and circuit, but I can not get it to actually show the pole number. It just shows the query in the message box. I know I am missing how to actually connect it to the database. I have connected the database to VB Express and then I dragged the polename column onto the form. This created my dataset. What I don't know how t ...Show All

• Visual Studio Team System Deleting a project from GUI

  I have removed (deleted) a project from the TFS database. However the project folder (although empty) still appears in the Folders section. Is there a way to remove this project folder Thanks, Kerry I am revisiting this issue of removing a project from the Source Code Explorer. I understand this to be a "bug" that has no current plans to fix. Our problem here is that we have old project and branches from the days of . . . (well, they're certainly very old and unuseful). There are so many of them the Explorer window is cluttered with these unnecessary entries. Having said that, is there anyway to manually remove the deleted projects from the Source Control Explorer It would seem this in ...Show All

• Visual C# Controlled Shutdown of a Consol Application

  Sorry if I have posted this in the incorrect section, but I wasn't sure where to post it, and as I am coding in C# I decided to put it here. The Issue I have several console application which need to perform a controlled shutdown. I create the Console application form code and store Process objects for each process created. I need to be able to tell if the process is still resoponding and hope to use the call Process.Responding to determine this (after first calling a Process.refresh()). When the creating application is told to it needs to shutdown the application in a controlled manner to allow for tidying up of resources and closing sockets. As such I am hoping I can call Process.CloseMainWindow. In both cases I have made the assumption ...Show All

• .NET Development Delegates/events short question

    Hey , I would like ask a few questions and I'd appreciate if  someone could clarify the issues for me. Firstly: what is the difference between a) this .Load += new System. EventHandler ( this .Form1_Load); and b) this .Load += this .Form1_Load both seem to work , is there an implicit cast to ( EventHandler ) in the b) case Secondly, how does the compiler treat function names like Form1_Load or any other In C++ they were seen function pointers, how does it work in C# Does the compiler understand function names as delegates The last thing is what does actually line a) do As far as I understand it, this line concatenates the invocation list of the "Load" event delegate with the invocation list ...Show All

• Visual J# J++ to J# Conversion Lots of Questions

  Greetings, I'm a developer for a large open source project ( http://immunesoft.sourceforge.net ) that was written in J++. Hats off to J++, at the time it was picked to start the project it was a very pleasant system to develop with J/Direct that allowed me to access system-level functions. This is very important for a security-centric system that needed to interact directly with the operating system and still be friendly enough for rapid development. I've pushed J++ pretty much to the limit, but its time to move on. I've been working on converting the Agent component over to J# 2003 (that's 1.1) but its taking a LOOONG time. At this point, I'm still seeing thosands of errors although I've made a lot of progress. I've got a pile of qu ...Show All

• Audio and Video Development WM/Picture in ASF Extended Content Description object

  I've some trouble to understand how data in WM/Picture is encoded. In the specification it says it should be compatible with the tag APIC from the ID3-spec.

From APIC in ID3-spec: Text encoding $xx MIME type <text string> $00 Picture type $xx Description <text string according to encoding> $00 (00) Picture data <binary data> WM/Picture data from a hexeditor (sorry for the formatting): 57 00 4D 00 W M 2F 00 50 00 69 00 63 00 74 00 75 00 72 00 65 00 / P i c t u r e 00 00 01 00 9A 6F 00 69 6F 00 00 69 00 6D 00 61 . .o io i m a 00 67 00 65 00 ...Show All

• .NET Development Reflection not working the way i expect it to

  If I use the code below, the instance that i get a reference to seems to have the non-public members I need access to, but not after i use GetType... //get reference to instance of SomeType Sometype _fred = Somelib.SomeType //now setup reflection Type fred_type = _fred.GetType() Now if I stop at this point, and look in the locals window, _fred will have non-public properties that I need access to, but fred_type WILL NOT. What am i doing wrong I need to use Type.GetProperty to get at a non-public property, but the search fails using fred_type.GetProperty(prop_name, BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public) as well as simply using this fred_type.GetProperty(prop_name) This is why I started looking in the locals ...Show All

• SQL Server "Do not replicate DELETE statement" feature problem

• Windows Forms Thanks, but I think I tried it before!

  Dear all, Me and my friend are new to visual studio 2005 express edition. We are trying to build a simple desktop database application. Now both of us have different connectionString to the database in our computers (which is quite obvious).At first, we used hardcoded connection strings in our apps. So it was a huge task to replace all those lines as we shifted our computers to share our works. For compatibality, we were trying to use the app.config file for the connectionString, which looks like : (in my computer) < xml version = " 1.0 " encoding = " utf-8 " > < configuration > < configSections > </ configSections > < connectionStrings > < add name = & ...Show All
