• Visual C++ Tips for speeding up debugging (stepping through code)?

  I've got one particular large C++ project that, in VC 2005, when stepping through code in the debugger, it takes approximately 2 seconds for each hit of the F10 key (i.e. each line of code) to be executed. I've tried many things to attempt to speed it up: disable intellisense, renaming feacp.dll, removing all additional output windows, watch, breakpoints, etc, removing navigation bar from text editor window, disabling anti-virus on the machine, closing all other apps. It's always the same speed. Running on a dual P4 2.8 gig with 1 gig of memory, and hyperthreading enabled. Are there any other tips for speeding up debugging in the ...Show All

• Visual Studio Team System How to: Add Data Binding to a Web Test

  According to this walkthrough: http://msdn2.microsoft.com/library/ms182546(en-us,vs.80).aspx I should be able take values from a Table Column and use them as values for QueryString Parameters. In my case, I want to use them as Form Post Parameters instead of QueryString but either way, I get the same result: First, When I add the Data Source, the thing says something like 'Invalid Object' when I try to run the test, My data Source is AdventureWorks1.vEmployee and the only way I have been able to get rid of this error is by editing the Data Source in the XML to say "HumanResources.vEmployee" in the <DataSourceTable> tag.

• Architecture OO design question.

  I'm trying to figure out a good way of looking this.. I have a "Product" class ( which is the fullblown class having all the child info and such )  and I have a subset class we'll call  "ProductSummary" ( where it is used as an instance of OrderItems - when people are ordering products ) which doesn't have any child info - at least for now.  I also want a very lightweight instance, we'll call "ProductInfo" ( and make it a struct ) that I can use to bind to a list with just ID, Title, SubTitle, Description, and Price. now the problem is that I want to have a field called .DisplayName which required in all three classes..  ...Show All

• Windows Forms Can you hide an item in the component tray at design time

  Hello, We have a custom collection which is based on component. Everything is working fine except that the component tray gets cluttered up with custom components which don't need to be referenced indiviually. Is there any way to hide them similarly, at least in concept, to applying a Browsable(False) attribute to a property Thanks in advance for any ideas and/or suggestions! Hi, You can add the [DesignTimeVisible(false)] attribute to your class. Note that this also means that your component won't show up in the toolbox. I am not aware of any way to make it appear in the toolbox but not in the comp ...Show All
