• Visual Basic FlowLayoutPanel Problems

• .NET Development .NET Remoting - Server should forward an ObjRef from one to another client

  Hello, I'm developing a client/server application by using .NET Remoting. Client- and server-activated objects works fine. But now I want to to create an object (e.g. StreamReader) on one client and send an ObjRef to the server. Then the server should forward this ObjRef to another client. Afterwards the second client should be able to use this ObjRef and read the file opened on the first client. The problem: in the configuration-file I have to specify the server's url, where the object can be found, but it's different each time. Is there any way to realize this Activator.GetObject takes as parameters a type and a URL and returns a proxy to that remote object. It doesn't matter where you take the URL from ...Show All

• Visual C++ Can I use POSIX threads in a atl STA project

  I have a library which uses pthreads inside of it. Can I use this library safely in a single threaded apartment project. If I can't what are my options . I want to use this library for building a com component. Thanks I wrote my component a little bit. This component use the C library to send HTTP messages. e.g. myComponent.Send("HTTP data"); Send() method uses the C library internally. The C library method should block until the response arrives and give me the response. The problem is that if the response take a long time to come the method just returns even before the response arrives. If the response arrives quickly it will capture the response. What could cause this kind of a problem. Actually this com component is a d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XACT won't set LoopEvent property

  Hi, I have a problem getting sounds to loop from within XACT. I open my project, open the Sound Bank window, select the sound name and highlight Play Wave - this causes the Event Properties panel to reveal LoopEvent, amongst others. Now, when I try to open the combo box to set "No" to something else, I get a dialog saying: "Object reference not set to an instance of an object." So, two questions: 1. Is there a way around this bug in XACT 2. Preferably I'd like to set the sound to loop from within my code. Is there a way to do this in Beta2 Many thanks =) Mark Hi Mark, I've seen a few variants on this error dialog popping up in the forums, but I haven't bee ...Show All

• .NET Development Connection Timeout

  I have a problem with Connection Pool running out of connections. I have a site which can get upwords of 1000 conncurrent hits at once. We never had problems with the connections when using classic ASP. But now we are running into the issue with timing out before getting an available connection. We are closing all of the connections. We have bumped up the max pool size to 700 but i don't feel this is really the right solution. Should we not use ADO.NET and go back to using ODBC as stated before we don't have this problem with our classic ASP which uses ODBC connections. Thanks for any help! If you actually have the potential for a large number of concurrent connections, I recommend going ahead ...Show All
