• Visual C++ LinkedList with node-objects

  Hi, i am currently working on creating a LinkedList, for that I using a predefined Node-class which offers a LinkedList Toolkit to manipulate the Linked List ( http://www.cs.colorado.edu/~main/chapter5/node1.h ). I develop a Squence-Class which should store a sequence of numbers in a LinkedList. My header file of sequence looks like this, respectively the methods and variables: [code] public: // TYPEDEFS and MEMBER CONSTANTS typedef double value_type; typedef std::size_t size_type; // CONSTRUCTORS and DESTRUCTOR sequence( ); sequence(const sequence& source); ~sequence( ); // MODIFICATION MEMBER FUNCTIONS void start( ); void advance( ); void insert(const value_type& entry); ...Show All

• Windows Forms How can I get a user-selected region of a picture?

  Hi, I'm trying to make an application with some photo-editor-like capabilities. I am displaying an image in one window and I want the user to be able to select a region of that image by dragging a rectangle. I am then trying to display only the selected region in a second window. I initially thought the PictureBox control sounded appropriate but after searching through a number of different forums I gather that PictureBoxes are really only for displaying pictures. Is this even the right control for what I am trying to do The first step for me is allowing the user to even drag a rectangle (similar to in MS Paint). I only want this dragging to be allowed within the picture display area, so would I have to use the MouseDown and MouseUp event ...Show All

• Visual Studio Solution file error MSB5009: Error parsing the nested project section in solution file.

  Hi, We have been running with MsBuild to compile and test our solution on a nightly basis without issue. A change was made to the solution whereby some projects where factored out into their own solution. So that we now have two solutions (at the root of SCC). The main one referred to by MsBuild and compiled nightly, and a subsidary one that contains projects only indirectly related to the main one. Since making this change we have the following MsBuild error on CoreCompile: "Solution file error MSB5009: Error parsing the nested project section in solution file." Both new solutions work fine in Visual Studio, we can get them from SCC, compile them, etc. We are totally baffled as to what this message means. Any help w ...Show All

• Visual Studio Subreports

  Hello everybody, I have a sub report that shows information for a particular topic when clicked hyperlink from the main report. On the sub report, I need to have another hyperlink that shows another report linked with sub report to show some more additional information.

• SQL Server DateTime Column not using Index

  I'm having a hard time getting one of my tables to use a non clustered index that I have on a DateTime column. A sample version of the table is something like this CREATE TABLE Appointments ( ID INT NOT NULL, AppointmentDate DateTime NOT NULL ) with a clustered primary key on ID and a nonclustered key on AppointmentDate. This production table has over 1million rows and the problem I have is this: If I do a SELECT * FROM Appointments where AppointmentDate >= '20060701' AND AppointmentDate < '20060702' the Non clustered index on the AppointmentDate column works fine. i.e. I'm returning all appointments for the 1st of July. Now if I run the exact same query using datetime parameters, a Clustered index scan is perf ...Show All
