Visual C++ MFC Question
(I cannot find a MFC forum here so I thought this would be the best place to post) I'm writing a program in C++ using VS.NET 2005 with the DOC/VIEW approach. I ran the wizard to generate the MFC project and I have the following .h files: MainFrm.h Resource.h Sketch.h SketchDoc.h SketchView.h stdafx.h I have the following .cpp files: MainFrm.cpp Sketch.cpp SketchDoc.cpp SketchView.cpp stdafx.cpp I have a very simple question - how I do I change the name of the window that appears I thought you go into the initInstance in Sketch.cpp and right before it shows the window, you invoke the SetWindowTitle method, but that doesn't exist on the m_pMainWnd variable, which appears to be CWnd. I hav ...Show All

Visual C++ Templates overloades and specializations
I want to create a function that returns the absolute value of a number. This number could be real (int, double, etc) or complex (of real, double, etc). I currently have the following: //--------------------------------------------------------------------- template<class data_t> data_t myAbs(data_t x) { return ((x > 0) (x):(-x)); } //--------------------------------------------------------------------- template<class data_t> data_t myAbs<complex<data_t> >(complex<data_t> x) { return (sqrt(x.real() * x.real() + x.imag() * x.imag())); } //--------------------------------------------------------------------- This compiles. However, when I call the function with a complex argument, the first function is c ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Integrating Joystick w/ DirectX9.0 and VB.net
I had successfully integrated a joystick using VB6 and DirectX8.0 ( ) a few years ago. I wanted to do the same thing with newer technology... I recently purchased VB.NETand a joystick thinking that the taks would be a cut and paste of old code with some minor modifications. I found that I can't download DirectX 8.0, and now I must accept 9.0. It seems as if every thing is skewed towards C# & C++ now regarding joysticks... My simple question: If I download 9.0 SDK (Managed code) will I be able to 'enumerate' the device and read it using VB.NET Advanced question: I noticed that 8.0 SDK method SetCooperativeLevel expected a windows handle that was type 'long', which is now 'int32' (or something similar) ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Optimizing meshes
Basically, I'm building a sort of Isometric Tiling engine in XNA, the same you see in games such as Civilization. Each tile in my 3D world is a mesh (cube), so many cubes form the grid or playing area. As expected, rendering many meshes at once slows down the game a lot. It can handle a 15x15 grid (225 meshes) but going over 20x20 (400 meshes) slows the game down to a halt. I'm not sure how they do it in modern games, but I'm assuming they build the terrain seperately and then represent it as a grid.. so that could be a possibility. I also thought of using sprites to represent the tiles but that (I think) severely affects the 3D stuff I can do, such as panning/rotating a camera or selecting objects. So what sort of optimizations c ...Show All

Visual Studio Team System Licensing Question
Can anyone tell me if I am correct about the following 1) For those owning Visual Studio Team Suite, there will be no cost for Datadude. 2) For those owning any other version of Visual Studio (Professional version and higher), there will be a cost for Datadude. If #2 is correct, can anyone tell me what the cost will be Our development team is using Visual Studio Team Edition for Software Developers. My understanding is that we will need to pay for Datadude.

.NET Development Expression Building - Access 2003
Good Evening All: The Scenario: I am running a report from clients that have sales reported daily, weekly, monthly and so on. I need to put an extra calculated field in the form in Access that determines the next time the client needs to report data. Example: Client "A" sent in data today and they report every day. Client "B" sent in sales today, but reports weekly. I need to add an expression to determine if client A sends today and they are a daily reporter, then the calculated field would display the next day. Same for a client that reports on a weekly basis. The field would calculate if they sent data in today, then 7 days from now would be the next time they would need to send data. Here is what I have so ...Show All
