• Game Technologies: DirectX, XNA, XACT, etc. z-buffer sorting?

  In experimenting with drawing multiple objects on the screen, I've found an interesting situation. I the picture below, the larger craft is closer to the camera, the smaller craft away from the camera. But if you look at it, the larger craft cuts into the shape of the smaller one, even though it is far enough away not to do that. In my drawing code, I know I'm drawing my smaller craft after the first, so there is clearly some kind of z-buffer problem. What I don't know is how to decide which object to draw first reglardless of camera positioning, or even if XNA has any help with that. Any ideas http://www.spellflight.com/images/zbuffer.PNG It's simple, just set these two render states before you draw y ...Show All

• Visual Studio Express Editions graphlite and vc++ express

  Hello. I need to create a graph in my program, and I am unsure how to do so. I can't find any resources on this matter, and no one seems to answer any questions about graphing in vc++.

• Visual C# user settings not the same for debugging

  Hi, anybody got a solution for this, its driving me mad. When I go to debug my application it is clear that the user settings are entirely different from when I just run my application, I see the two folders and their local user.config settings. during development i'd like to see these as one file, so if I find an error i don't have to duplicate the same settings when I go to debug the app. its getting a little tedious! cheers I mean there are two folders under C:\Documents and Settings\spang\Local Settings\Application Data\myappname one is myappname.exe_Url_<md5string> and the other is myappname.vshost.exe_Url_<md5string> which is the debug settings ...Show All

• Windows Forms Is there a way to convert a control to a different type of control?

  I want to convert a textbox into a label. Is this possible Short answer: No. Since System.Windows.Forms.TextBox doesn't inherit from System.Windows.Forms.Label, you can't do this conversion. Could you please elaborate a bit on what you are trying to accomplish here You could create a new label and assign the value of the TextBox's Text property to the Label's Text property. Or you could make the TextBox read only and change its BorderStyle to BorderStyle.None to make it look more like a label... Best regards, Johan Stenberg ...Show All

• Visual C++ help with linked list

  I'm having some problems with linked list. I'm working on a small program that deletes a node somewhere in the middle of the list. I don't seem to understand what is wrong with this code below. I know the syntax it correct, but when I try to delete a node somewhere in the middle, it deletes that node just fine, but I believe that I'm not tying my pointers together right. Deleting is not the problem, the problem comes when I display the list again. I will display before I delete the particular node I want, but after the node is deleted, it crashes the program when I display the list. I've tried this one several different ways. (#1, using a temp node to "bookmark" my spot at the node(current) for deletion) temp=current; pr ...Show All

  How to execute "msiexec /I ...." i tried through Process.Start, but it doesn't work Try to specify the absolute path or add the path to your path environment variable. I am guessing that the system does not know where to look for msiexec. A quick test would be to open a command prompt and type in msiexec and see if the command is recognized. ...Show All

• Visual Studio Express Editions Basic class help......

  Hi, I'm trying to create a static int and I'm getting the following error... Error 1 error LNK2001: unresolved external symbol "private: static int moodyCritter::_threshold" ( _threshold@moodyCritter@@0HA) critter.obj Here is a snippet of code... class moodyCritter: public critter { private: int _angerLevel; static int _threshold; Any ideas When you define a variable within a class as static, it is actually not part of the class object. Instead it is declared only within that scope, but needs to be defined in any file that uses it. Example: class A { public: A() {}; ~A() {}; static int myStatVar; }; int A::myStatVar; int main() { } ...Show All
