• Visual C# Call Method From External Process

  I'm not sure if this is possible, but I need to call a method in a running program from a different program. The method I want to call is being loaded into the remote EXE via a DLL. If I try using DllImport, it does call the method, but it doesn't work correctly. The method is supposed to return its class's member information, but if I use the DllImport from C# to call the method, it doesn't return the actual remote class's members, just some garbage values. Also, the program and DLL were written in C++. For example, TestApp has a class called TestClass. This class has a bool called TestMember and a method called TestMethod that returns the value of TestMember. When I write a program and use DllImport to import TestMethod, it returns true, ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Missing sprites

  I am developing a racing game with DirectX 9.0c and VC++ 2003.NET. When I use the retail version of direct3D some of my sprites dont show up, when I switch to debug version of direct3D, all sprites appear once again. Tools >> Options >> Debugging >> DirectX is where i change from retail mode debug mode of Direct3D Why would this happen Debug mode checks your parameters a little better than the retail mode so maybe you are doing something strange that the debug runtime is allowing through. If you increase the debug out put to full in the DX control panel do you see any errors or warnings go by ...Show All

• Visual C# To _, or not to _?

  The .NET Framework is littered with private variables preceeded with the _ (underscore) character. Is this good practice Or something Microsoft are trying to stamp out Hello, This is truly a debatable topic and many discussions has been already done on it. I would like to contibute a little on it. I worked on .Net Coding standard for my organization about a year back. And from my Study I learnt that Microsoft is moving intentions of their programmers community from old m_ or _ style to new standards which are recomended to be used in .Net. use of "_" and hungarian notation is forbidden. As many other people have said that it depends on the way you feel comfortable I go with this stateme ...Show All

• Visual Basic Application hanging on Serialport .Close method

  This one has me stumped. I've created a class to interface with a device on a comm port. I've decalred the serial port: Private WithEvents moPort as System.IO.Ports.SerialPort In the New event, I create the port and open it, works great. I communicate just fine, handle everthing going in, coming out no problem. When I go to close the port, by just a .Close command in a "Disconnect" method I've defined or in the IDisposeable implementation, the entire program hangs up. I can hit Pause in the IDE and it highlights the "moPort.Close" line, the call stack always shows something like: [In a sleep, wait, or join] [External Code] Executablename!ProgramName.ClassName.Dispose(boolean Disposing = True) Executablename!ProgramNa ...Show All

• Visual C# C# 2.0 closures - bug or feature?

  Would anyone care to explain me what is happening there To me, both i and ii seem to be local variables within the same scope, so why the compiler treats them differently using System; using System.Collections.Generic; internal delegate void VoidDelegate(); internal class Program { private static void Main() { List< int > a = new List< int >(); for ( int i = 0; i < 10; i++) { a.Add(i); } List<VoidDelegate> handlers = new List<VoidDelegate>(); foreach ( int i in a) { handlers.Add( delegate { Console.Write(i); }); //If we comment out line above and uncomment two lines below, we'll get the expected "0123456789" result. //int ii = i; //handlers.Add(delegate { Console.Write(ii); } ...Show All

• Visual Studio Team System Associating work items and changesets

  I am trying to use < UpdateAssociatedWorkItems > true </ UpdateAssociatedWorkItems > however, I can't find any documentation on how it works. I am trying to add build to the bugs that have been resolved so that they can show up in the "associated work items" and "associated changesets". I am not sure how I need to flag my bugs/tasks so that UpdateAssociatedWorkItem would work. Please help. This should all just work by default... That is, changesets should automatically be associated with builds in the same team project (it's a bit more complicated than this, but to a first approximation this will be true). Work items should also be associated with builds, so lo ...Show All

• Visual Studio Team System Problem with source control, web projects and the bin directory

  Hi I have a problem with web projects and source control. It appears that the bin directory is automatically added to source control. This is causes a problem whenever anyone compiles the solution as the same binaries are attempted to check in and of course someone has already checked out and locked the binary. I assume if a change is made to a binary it is automatically locked. Unfortunately even though I have deleted the bin directory from source control whenever the solution is compiled it tries to add the binary to source control again. Does anyone have any suggestions on how I can get around this. Cheers Brett Hello, I have a similar problem. We have a Web App with a lot of references, and every time we do Check I ...Show All
