• Windows Forms System.CodeDom.Compiler.GeneratedCodeAttribute error

  I downloaded a sample from MSDN for VS 2005, and tried to build it (using VS2005) as described in the documentation. I obtain 7 errors in the NorthwindCustomerOrders.XSD (NorthwindCustomerOrders.designer.vb file) saying that Type System.CodeDom.Compiler.GeneratedCodeAttribute is not defined.

It says I have to open the .Net framework SDK 2.0 command prompt but next instructions are missed. Can you help me Thanks a lot Here is the path from where I downloaded the sample: visual studio 2005 documentation - visual studio - samples - technology ...Show All

• Visual C++ Custom Preprocessor as Custom Build Step

  I was reading an article in GameDeveloper recently that suggested an interesting method of using strings as object IDs.  Since strings are expensive to compare at runtime, hashes of those strings are often used for comparison and identification.  The article suggested using a custom "macro" called HASH() which would be evaluated to a CRC hash value during the build.  For example: //in the source code Load(HASH("MDL_MECH01_LARGE")); //the same line after the custom build step: Load(0x334BDCF8); The benefit of this method is that the programmer doesn't need to worry about the hashes of the strings, an ...Show All

• Windows Forms Making a scrollable panel scroll with mousewheel just by hovering mouse

  Hi, I have a particular problem with a possible solution and I am interested in hearing peoples opinions if it is the right way to go about it (or not  ) Some applications I have come across, such as Firefox, will allow the user to scroll the document window just by hovering the mouse over the display area and using the mouse wheel. You don't have to focus / select the display area first. With Firefox, the address bar can have the focus and the keyboard input but you can still scroll the document. Contrasting with IE and Visual Studio, you have to click into the document area before it responds to mouse wheel messages. In my ...Show All

• Architecture Two Controllers sharing one model

  Hi, really hoping that a) I've posted this in the right forum, b) that someone can help me out. I'm implementing a MVC pattern that contains two controllers that both need to access the same instance of a model. I'm having problems trying to work out how to get the controllers to share one instance of an model. The model can't be a singleton object and each instance of the model contains it's own data, so the data cannot be static across all model instances. I'm thinking of using a third controller that contains the model instance and the other two now child controllers. All events raised by the views notify the child controllers that ...Show All
