• Visual Studio Express Editions some classes do not show up in class view

  Hi, I have a workspace, consisting of 4 projects. Two of the four projects are missing some classes in class view. And when I go into the .cpp file, the "Functions in ***.cpp" appears to be blank. Does anyone have any idea why I even updated to Visual Studio Professional, but the problem remains. - xin Another option that sometimes works is, do a full clean of your project, including manually removing any non-source/project files, close the class view then restart visual studio, this forces the class viewer to rescan your source, but as i said earlier, if the source contains strange whitespace, anon-enums etc it can confuse the class viewer. If intellisense is continually updating, and providing ...Show All

• Visual C# how to check the type of an object?

  let's say i want to see if a control is of type checkbox ... if(control is CheckBox) { //do something } is this the right way or maybe CheckBox cb = control as Checkbox if(cb!=null) { //do something } thanks, C# has numerous ways to check and object's type, and there are many situations where one would need this.  This happens because the code that has the reference to the object did not necessarily create it, and may not know what the object's exact type is.  A common place where this this kind of code appears is in an override of the Equals method in a class derived from the System.Object class.  The parameter you are passed is of type object, but you need to first check ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Advice on Controller Vibration

  Hello, I am looking for some guidance on best practices for vibration effects. I don't want to ruin anyones hardware or burn out motors by using settings that aren't friendly to the controller. I have a couple of questions: 1) Is it acceptable to use "pulsed" effects by calling GamePad.SetVibration() every Update() to change slightly change the motor settings, creating the feeling of "punches." 2) Can that pulsing include complete stops of the vibration 3) Is there any guidance on maximum suggested duty cycles for using the vibration (Not that I plan to leave it on much, but should I be intentionally limiting the duty cycle if the player engages in non-game behavior like punching all the time for 10 minutes ) 4) Is the ...Show All

• SQL Server Creating a DECLARE variable with SMO

• Game Technologies: DirectX, XNA, XACT, etc. BoundingBox

  Thanks to XNA, my fragile vision of 3D space is completely mangled. This -1 forward thing has really whacked my ability to determine coords in 3D space. I'm making a bounding box for a ray test, and I want my minimum to be (-1, -1, -1) and max to be (1, 1, 1). In MDX 1.0, that would have been fine. Do I have to reverse the z coords for this to work in XNA I have no idea what you are talking about. XNA has a BoundingBox structure and a Ray structure, and the Ray structure has an Intersect method to check for an intersection with a BoundingBox.

• SQL Server Comparing millions of records from file A and B

  I'm trying to compare about 28 million records (270 length) from table A and B using the Lookup task as described in this forum. The process works fine with about two million records or so on my desktop ( p.4 3.39GHz, 1.5 GB Ram), but hangs with the amount of data I'm trying to process. I tried using full and partial caching, but to no avail. I'm thinking this is a hardware resource problem. So, does anyone has any recommendation on the hardware needed for this kind of operation and/or suggestion Thanks in advance...

• Visual Studio Tools for Office RTD server as exe file

  Hi all! We've got a C# client that fetches data from the netword and presents it in its on GUI. This works fine. Now we would like to make the same data that it fetches available in Excel as well, through IRtdServer and RTD()-calls in Excel. I've managed to create a simple DLL (from the Microsoft RTD examples) that is registered with regsvr32 and is available from Excel. So this works fine as well. Now I would like to enhance the exe-application we've got by making it into an IRtdServer as well, and I've naively just added the classes I implemented to make the DLL to my exe-project (and added the appropriate resources, so everything runs and compiles nicely). But I can't get Excel to find the new RTD server. The RTD()-call yields a #N/A re ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rendering multiple viewports

  Hello community, I've created a couple of components that allows you to render a 3d model in space, and it has a camera that allows you to move around in space. Right now, I want to be able to define multiple viewports with different camera angles so I can view the scene from different perspectives. I know it isn't quite hard to accomplish this with MDX, however I can't find any code on how to control the device using XNA. All help is very appreciated, thanks! Could you introduce a base class that derives from DrawableGameComponent and introduces the camera as a property I would recommend moving to Beta 2 ASAP as we'll be focusing on answering those questions rather than Beta 1 questions. ...Show All

• Visual Basic Reusing Forms

  Greetings I am converting a VB6 program containing multiple forms into a 2005.net VB program. In the old VB6 program I use a modal form and then I want to re-use the same form but but change some of the labels and make visible a control that was invisible the first time around. In the VB 6 version I was in, say, Form1 and executed the following code: Unload Form1 Form1.Show 1 This re-did the Load event and I used a counter to customize the form in its second life. Is there any way to do this simply in VS2005 VB Thanks again for the clarification.  I wonder if I could trouble you with the current state of my problem.  I have made some progress but... As suggested I created an in ...Show All
