• Visual C++ Program runs slower when compiled with Visual Studio 2005 (in Release with optimization)

  Hey, I have a performance problem with the new Visual Studio 2005. My code (which is a genetic algorithm) is 3 times slower when compiled under Visual Studio 2005 compared to when I was compiling it under Visual Studio 2003. With Visual Studio 2003, it used to run in 3.0639 seconds, and now it runs in 9.0031 seconds. I run both code in Release. I tried every optimization option, and adding the /D_SECURE_SCL=0 compiler command to the project options with only minor differences. Is there any other way to get back to the speed Visual Studio 2003 It is a bit absurd to upgrade to a new compiler and get lesser performances. Thanks a lot!!! Antoine ...Show All

• .NET Development Remoting Server and multiple clients

  Hi, I have implemented a remoting server application that host a remote object that is refernced by multiple client applications.(SAO, singleton). Windows applications. Thus, it is straightforward that client applications use the proxy object hosted by the server to invoke methods directly. This is a straightforward request-reply mechanism. However, in order for the server to notify multiple clients, the client applications have also hosted a remote object. The server can then create a proxy object hosted by a client application and invoke methods directly. (such as notify() ); However since there are multiple clients, and each cli ...Show All

• .NET Development Dispose and Application Lifetime Objects

  Hello, I have a Windows Forms application. When the app first runs (Form_Load) I create some disposable objects that will be used throughout the lifetime of the applicaiton (eg. a GDI Brush, SqlConnection etc). Do I really need to call Dispose() on all of these objects when the application closes, or will Dispose be called automatically for such objects when the app closes In other words, can I instantiate a disposable object when my app first runs, and not worry about disposing it when the app closes What about if my application terminates due to an exception Many thanks for your advice.

• Visual Studio hotfix for visual studio .net 2003

  Sure.  I just purchased the academic software last week for a night school course.  I installed it without errors.  Problem 1) When I go to the tools > upgrade it cannot find the page of the upgrade. Problem 2) For the library problem.  I decided to have a look around and read the help files.  I had already installed the  mdsn libraries.  However, when I try to start up the help files, it opens what looks like a browser, and then says server not found. It looks like the browser that is inside the tool does not work.  I have attempted to use the same pages on my internet explorer and they work fine. ...Show All

• Windows Forms Limitations to FlowLayoutPanel

  I am using a flowlayoutpanel control to display a list of controls and it seems to only show the first 149 properly. Then it seems to chop the 150th in half and not show the rest. (My test case involves adding 395 buttons to a flowlayoutpanel). I was wondering if there was an express limit on the number of controls I can add to the panel or if it's a memory concern. Also, can I change the number of items allowed Any help would be appreciated. Thanks, Liam Hi Liam, Based on my test, there is no known issue for this limitation. This may be caused by many possibility. e.g. Memory, GDI h ...Show All
