• Windows Forms Drag & Drop: control vs container

  Hi, I have implemented a user control (MyControl) for which I have set AllowDrop to true and overriden OnDragOver. I have also overriden OnDragOver in my Form derived container (call it MyForm). When I drag a file from the explorer onto my form, MyForm::OnDragOver is called and when I reach the client area of my control, MyControl::OnDragOver is called, but no longer MyForm::OnDragOver. My question is: is there a way I could still have MyForm::OnDragOver called if MyControl cannot handle the data being dragged Chris. The easiest way would be to just have your form handle the DragOver event for ...Show All

• Visual C++ error CS0229: Ambiguity between 'XX.Name' and 'YY.Name'

  I tried to implement the following scenario in VC++ 2005 beta2: an object implements 2 interfaces, one defining a property get and the other defining a property set. This works perfectly well when implemented in C#. However, in C++, I get the compiler error message transcripted below. Here is the C++ source code: namespace NS {  public interface class INamed  {  public:   property String^ Name   {    String^ get();   }  };  public interface class INameable  {  public:   property String^ Name   {    void set(String^);  &nbs ...Show All

• SQL Server Lookup - full caching vs partial caching vs no caching

  I needed to do lookup on tables with approx 1 million records (how else do I know if record already exists ). Full caching: SSIS caches all million records (consuming around 1 GB RAM) and cripples my lowly system with only 1GB physical RAM. This works for now, but the lookup tables will keep on growing. This means that full pre-caching may not scale for this scenario. Partial caching and No caching: I don't really know how SSIS works in these modes. I can make my guesses but it will be great if someone can explain those. The behavior that I see when I use partial cache of varying sizes or when I use no cache at ...Show All

Also I didn't find any option to implement MPUT/MGET in FtpWebRequest . Any suggestion on how to implement such things is welcome. Thanks in advance. Please set the KeepAlive property ...Show All

• Visual C++ Unit testing unmanaged code

  Over the last few years we've been writing an application that has a number of modules and DLL to make up the core product - most of the code is written in unmanaged C++ dlls, which use STL - the Wn32 Interface is all C++.NET though, which calls these DLLs.  This is done to give us the ability to use the core code under other OSes (eg, MacOSX).  Unfortunately, it looks like Microsoft are doing everything possible to make non-C++.net development difficult.  Oh, how nice it would be if Unmanged DLL Unit Testing were an easy task. It seems, if I compile my unit test with /clr, and include my header files for the classes tha ...Show All

• Windows Forms Bringing controls out from design-time

  I'm using standard DesignSurface for control design in my custom editor and I'm trying to serialize designed controls with my custom serializator that simply recursively parses the root component and emits custom serialization data for each and every component. The problem is that some components contain objects that were created by their designers. For example, the MenuStrip in its Items collection has a DesignerToolStripMenuHost object that is used for designing menu items. My serialization process cannot generically differentiate these design-time objects from real ones. The solution could be to remove the components from design-t ...Show All
