• 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

• Software Development for Windows Vista Host Workflow in Windows Service

  Is it possible to host workflow in windowsService if possible how You can do this just how you'd host it on any other kind of executable. Basically you'd create an instance of the WorkflowRuntime engine in your service as part as your OnStart operation. Any of the basic workflow hosting samples should get you started on this, or even just creating a basic Console Workflow project to see the basic code necessary. You can also configure any necessary workflow services you require on your engine by using the app.config file or by using code (runtime.AddService()). ...Show All

• Visual C++ Need construct for member relative location placement in huge structures

  Here is the problem :  I have this huge structure whose members have address restrictions (e.g. member x starts from relative address y from the base pointer B).  The address restricted members(from base) are needed to satisfy the hardware device register specification of the device.  For example, typedef struct _DeviceRegMap {     struct PCIDeviceHeader PDH;  // Bytes 0 - 199     //put fillers here as the next structure should always     //start 300 bytes (absolute) from the base of this structure     BYTE filler[100];     ...Show All

• .NET Development Possible to add to a strongly type collection, an item of not the same type?

  In 1.1 given a collection w/c accepts only a specific type, is it possible to add an item that isn't of the same type ex. public class myType { public int myField;} public class MyCollection:CollectionBase { public int Add(myType m) {return List.Add(m)} ... } You can add items of that specific type or a derived type.

• Visual Studio VS2005 Team Suite Beta 2 fails to install on clean SBS 2003 system

Despite having removed almost everything from the system it still says:  "A failed installation has been detected. Press OK to uninstall the product. Then retry installing." I ran the VS2005_Beta_Cleanup_tool successfully to no avail.

• Visual Studio Team System Application types

  Is the list of application types and endpoints in Application Designer now the defiinitive list for Version 1 Can I define and add my own types into this Hi Ian, This is the final list for version one. You can define new types in a couple of ways. If you want to customize one of the existing types, you can create a prototype. For more info, see http://msdn2.microsoft.com/library/ms181862(en-us,vs.80).aspx If you want to define a new type, you need the SDM SDK.

• Visual Studio Team System When I get a specific version why does the contents of Source Explorer change?

  The objective of the Source Control Explorer is to display the contents of the TFS repository; is that correct Therefore the folders pane should show the current folders in the repository for my Team Project and when I select one of these folders the right pane should show the current contents of that folder in the repository. By 'current' I mean 'latest version'. Given the above, I find the following behaviour strange... I copy a specific version of my Team Project's source code into my workspace (select the Team Project folder in the folders pane, right-click | Get Specific Version). Although this does not change the TFS rep ...Show All
