• Visual Studio File, Save As fails with a managed Language Service

  Allen Denver's RegEx Language Service sample (see gotdotnet, http://www.gotdotnet.com/workspaces/workspace.aspx id=2c0db3c9-a3bd-4116-bc1f-6c84a898e034 ), is registered against .foo files. When a .foo file is loaded, then File, Save As... doesn't work. A message box saying "The operation could not be completed. The parameter is incorrect" is shown. This is on the RC build. This also happens with the Language Service I'm trying to write. It works fine with the Xml Language Service. Anyone know what I need to implement in a manged language to make File Save As work Mark. I found the answer. You ne ...Show All

• Visual C++ Unmanaged void* to .Net System::Array

  I have an unmanaged C++ class representing a 2D matrix. It holds a pointer to a block with the actual data, and fields indicating the number, size and type of the matrix elements. Like this: public class UnmanagedMatrix { public: void * block; long rows; long cols; int type; //refers to an enum of possible types - char, long, double, etc. long sizeOfBlockType; ... } I am writing a managed wrapper to use this class from within .Net with a member pointer to the unmanaged class in the usual way: public __gc class ManagedMatrix { private: UnmanagedMatrix __nogc* pM; ... } I need the wrapper class to get and set the unmanaged block ...Show All

• SQL Server Connecting to Sybase

  Hi, I am assuming someone has had success connecting to Sybase from SSIS. I am having trouble. And I freely admit naivety when it comes to something like this. :-) I installed dbConnector 6.01 which has a Sybase connector as a part of the package. I then tried to create a connection manager for Sybase using OleDb, but it was not an option in the list of OleDb connections. So, am I correct in assuming that I need to use ODBC If so, is there an OleDb Sybase driver that can be used with SSIS Any help in using SSIS to connect to Sybase would be appreciated.

• Game Technologies: DirectX, XNA, XACT, etc. Ways of Rendering mouse cursor in directx9

  I'm trying to build a GUI using directx 9. I find that rendering mouse cursor is something different from the main rendering process. It needs to have higher priority to make cursor looks "smooth" even when main rendering process's frame rate is low. Others give me some advice, but I'm not sure which is better. The following are the ways I figure out. 1. Using windows mouse cursor.  It's fast but in full screen mode it failed. 2. Drawing cursor in seperate thread using windows GDI. The cursor is just blinking. 3. Drawing cursor in seperate thread using directx. I don't know how to do that. Should I share the same d3d device or ...Show All

• .NET Development Dynamically loading DLLs in ASP.NET

  Hello, We would like to be able to change the business components (in DLL) of our ASP.NET (VB) web site without resetting our application. One solution that is/seems possible is by loading the business DLL in a second application domain and unloading/reloading the DLL in that domain. This approach however comes with a severe performance penalty due to the marchalling that occurs with each call over the application boundary. Using a web service is another alternative, but is also much slower then using a DLL loaded in the same application domain as the web application. Due to the load and nature of our application this performance l ...Show All
