• .NET Development Problem with BackgroundWorker

  OK, Here's my scenario: I have an application that includes a Search form for various items.  I have implemented a search algorithm that takes advantage of the BackgroundWorker class to do the search asynchronously on the search form.  My application allows the user to open multiple search forms and search on different criteria. The search form and backgroundworker class work beautifully when only one search form is open.  If the ...Show All

• Software Development for Windows Vista Workflow.ComponentModel.Activity / Workflow.Activities.SequenceActivity

  Hello I'm writing a custom activity and I wonder what's the basic difference between a Workflow.ComponentModel.Activity-derived activity and a Workflow.Activities.SequenceActivity-derived one.

If you derive ...Show All

• Windows Forms Type.GetType and Colors

  I have a code editor where I use reflection to lookup types descriptions. If I have code like this: Type type = Type.GetType("System.Drawing.Color, System.Drawing"); the variable "type" is null. Does anyone know how to use the Type.GetType function to get the Color's type I cannot simply use Color.GetType() because this is for a generic code editor that does not already have the type definition for all classes in all loaded assemb ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. OpenGL Rendering Context + DisplayDevice (not window) Device Context?

  Is it possible to use a Device Context for a Display Adapter (not a particular window's DC) with OpenGL   The primary reason I am trying to do this is that I want to render OpenGL on multiple monitors, but the monitors are not necessarily members of the Windows desktop monitor group (and thus cannot have windows on them).  Here's some of my test code.  Everything seems to work until I call wglMakeCurrent(). dc = CreateDC( _T(" ...Show All

• Visual C++ a compiler bug

  Hi, just found a bug in vc 2003 c++ (and c ) compiler. The problem happens when i use shorts to iterate over a vector and when speed optimization is turned on. The problem is that full 4-byte register is used for indexing the vector and the upper part of the register can contain garbage. The code works well in debug mode, the poblem arises only when I turn on speed optimization. Let me know if this is an unknown dug - I'll provide details. BR V ...Show All

• .NET Development Binary Serialization and byte value of 255

  I have a problem while trying to remote some classes in that after I serialize the outstream (using the standard binary formatter) sometimes it places binary values of 255 in the header which the crypto engine strips out (on a decrypt function). Is there any way to either make sure the binary formatter doesn't serialize 255's in the stream or to make the crypto engine leave them in there on decrypt Thanks!! ...Show All
