Visual C++ Accessing ref class when operator -> is redefined
Hi, i know this is probably a silly question, but the fact is i can't realize how to do this. I have a ref class with operator -> redefined, but in a specific point of my code i want to acces a member of this class. Example: class N2 { public: N2(NativeClass nc); }; ref class RC { public: ... NativeClass* operator -> () {return m_p;} static operator N2(RC^ rc) {return N2( *(rc->m_p) ); } private: NativeClass* m_p; }; Since i can only acces the class with -> the conversion operator to N2 doens't compile. Any help Thank you. Yeah. Switching to a tracking ref isn't the best solution is it. Try this: static operator N2(RC^ rc) { return N2( *((*rc).m_p) ); } ...Show All
Visual Studio Tools for Office Assembly Reference Error
Hello, I have been working on a project that imports images from powerpoint, and have built the program just fine many times. I made a few changes to the code, and now I am getting the following error when I try to build: Error 1 The type 'Microsoft.Office.Core.MsoTriState' is defined in an assembly that is not referenced.

Visual Studio Express Editions Dynamic assignment of data type within a structure...?
I'm wondering if there is a way to assign a datatype to a variable within a structure dynamically at runtime. For example: Structure test Dim a as Integer End Structure Is there a way to make variable "a" dynamic at runtime, so that it could be "as Single", or "as Byte" based on conditions at runtime Meaning, each instance of the structure may have variable "a", but representing a different data type... If not, any suggestions on a way to implement something like this I'd like to expand on my question, if I might. Lets suppose I needed to manage a dynamic array of that same structure throughout the course of my application. How would I assigned different types i ...Show All
Visual Studio Express Editions Using TabPages as MDI - need some help please
I am working on an application where I want to use a TabControl with multiple TabPages to display multiple documents. My application starts up with TabPage1 having a certain set of controls (a few textboxes, a datagridview & a button). I want to be able to have an event (a button click perhaps) cause a new TabPage to be added to the TabControl & be populated with the same controls, in the same locations, that are on TabPage1 (which were created at design time). I have pretty much figured out how to add the new TabPages, but here's where I get stuck: 1) How do I duplicate the controls that are on TabPage1 to the new TabPages 2) How do I address the controls that will be added to the new TabPages ie. the DGV that is TabPage1 is call ...Show All

Software Development for Windows Vista Problem in driver development in Vista
Hi, I'm in development of a driver for PCI card in Windows Vista (Build 5308). I faced a problem probably due to its "shadow copy technology". Suppose i have installed my driver on system. And then made some changes and build. whenever i'm going to install this updated version(with respect to build time-stamp) vista is not using the updated version. Its using the very first version(with respect to build time-stamp) installed on the date although it keeps backup of the updated version. I have attempted a number of alternatives: 1) Restored an updated version from "previous versions" tab. Its worked fine only for the next restart. and 2nd time onwards uses very first version of the date. 2) i suppose its due to shadow cop ...Show All
