• .NET Development Exception when client app try to connect to a server event

  I write simple .net remoting app to understand this technology. I have server and client app. Remote object: public class JobServerImpl : MarshalByRefObject, IJobServer{ ... public event JobEventHandler JobEvent; ...}When client app try connect to JobEvent,m_JobServer.JobEvent += new JobEventHandler(this.MyJobEventHandler); it raised up an InnerException - Cannot load file or assambly JobClient.exe.

• Visual Studio Express Editions 2 events at once

  I'm creating a simple, old, black and white tennis game for practice. I've created an event handler for 9 keys - 2 for moving 2 paddles up, 2 for moving them down, 2 for left and 2 for right. I also have an Enter key that starts the ball moving. The problem is that when I press Enter, none of my other keys work, until the ball goes off the screen. Does anyone have any suggestions how to fix this If you provide mode detail, someone might be able to provide some guidance. I'll assume this is a WinForms application. What event are you subscribing to to handle the keys, KeyDown, KeyUp, or KeyPress What is the c ...Show All

• SQL Server Web App Failover problem

  Hi, I have successfully set-up a DB mirroring. When the pricipal goes down, the mirror picksup and the other way around too. So the mirroring part is working great. However, when I use my web applicaiton (dot net 2.0), it is not able to connect to Mirror server . I get the following error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) My connection string in web app: &q ...Show All

• Visual Basic Access Database and Bin Folder

  I hoping someone can help me out here. I had a similiar problem on a recent project, and I just copied all the files to a new project, and that cured it. But I wonder am I doing something incorrectly. My project has an Access database. It is added to the project. Lets just call it DB_Original J:\AssetNet\AssetReg\AssetReg\Assets.mdb When the project runs, it updates data in DB_Debug J:\AssetNet\AssetReg\AssetReg\bin\Debug\Assets.mdb If I change data when the project is running, DB_Debug is updated. However, when I stop the program running, DB_Original is not updated. So if I add assets for testing, I have to re enter them every tim ...Show All

• .NET Development Marshalling COM interface between threads--help!

  I am developing a Windows Forms 2.0 application that references a COM primary interop assembly to communicate with a COTS product. I am still very new to working with COM from .Net and the threading issues that are involved, so I am unsure how to marshall a COM interface between threads--I have the main UI thread, of course, but for many of the data access calls I use a BackgroundWorker component to execute the calls asynchronously. The issue I am having is that I am attempting to maintain a single instance of the Database object (part of the COM API) because creating it is very resource intensive, but I am getting an exception that the work ...Show All

• .NET Development How to serialize an object wich is marked as non-serializable ?

  Hi, I'd like to serialize/deserialize (xml or soap) an object wich is not serializable. I don't have sources of the object. I tried to declare a new serializable class, who inherits from the object class, but it doesn't work. Is there any other way to "record" an object (properties & values) Thanks Vikram, I tried using surrogate but there's an error "The method or operation is not implemented." when i call serialize method. It works with simple objects (like array os string) but not with more complex objects. When it doesn't work, " GetObjectData" method is called, else, it's never called. Apparen ...Show All

• Visual Studio MS ANtispyware blocks unit test tool

  Hi All, Have any of you experienced problems with the Unit Testing facilities of VS.NET 2005 beta 2 (on a C# project) being blocked by MS Antispyware It appears that the environment autogenerates a batch file each time the unit tests are to be executed. I am not sure how to stop MS Antispyware from objecting to this each time I run the scripts. Please let me know if you have a workaround (that doesn't compromise the security of my machine).
