• Visual Basic Can anyone recreate this small bug?

  New windows form Add a Menustrip and a couple of items Add a Toolstrip and a dropdown button with a couple of items Set the shortcut property of a menu item to CTRL + SHIFT + F9 Set the shortcut property of a different menu item to, e.g., CTRL + F9 Set the shortcut property of a toolstrip dropdownmenu item to CTRL + SHIFT + F9 Set the shortcut property of a different toolstrip dropdownmenu item to, e.g., CTRL + F9 Create two simple subs and have one handle both the C+S+F9 click events and the other handle the C+F9 click events Run the form. On my install, CTRL + F9 works, but C+S+F9 does not. However, if you remove the shortcut key from one of the menu items (so there is only one C+S+F9 shortcut on the form) t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Video/Animation Playback

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All

• Visual Basic Add and remove data from file

  Is t possible to: Add data to a certain offset in a file without overwriting original data from that offset, thus expanding the file Remove data from a certain offset and length in a file, instead of making a new file of the two desired parts of data from the original file Thanks! Sure performance may be an issue with files this size and the stringbuilder class may be the best option. Also remember windows uses virtual memory, so it will page items in an out of memory if you dont physically have 100Mb free in your machine at the time. Are we talking like a batch process to update this file or are you talking about an interactive application - Is it possible that you could use a database to do interactive parts of ...Show All

• SQL Server Floating Point Error - Order By Mystery

  I'm having a problem that I think is due to corrupt data. Depending on the column I use in my order by clause two problems are occuring. 1. No results are returned and I get this error: A floating point exception occured in the user process. 2. Results are returned but there are a different number of rows depending on which columns I use in my Order By clause. Examples SELECT * FROM SymbolStats ORDER BY calc_date, symbol Returns - 12207 rows but only includes one of the 25 dates in the table. ---------- SELECT * from SymbolStats ORDER BY current_hv Returns - 0 rows. ---------- SELECT * from SymbolStats ORDER BY average_hv Returns - floating point error With more conditions in the WHERE clause the number of results returned varies gre ...Show All

• Visual C++ Question on including header files to project in VC++

  The question might sound dilly but couldnt find a proper answer. I created a new project in VC++ 6.0 and included an existing header file into it but when I try to use it in a cpp file (also in the same project), I still have to include the header file specifying its exact location. I thought if i add the header file to the project, i can just write # include "xxx.h" in my cpp file and the header file would be automatically found. Instead I am having to write the path of the header file in the include. Am I missing something Thanks, KarthikR If the file you mentioned(header) is in same folder as cpp you want to include this header in, then # include "xxx.h" will work. xxx.h must be ...Show All

• Software Development for Windows Vista Restart Manager and Windows Services

  Hi there, I'm trying to get rmtool.exe to shutdown a windows service, but it doesnt seem to handle the shutdown messages, even though there are three messages handlers that have been added to it, one for service control messages, one for ctrl-c messages and one handling windows messages, and still no response from my service. I think I might have the wrong syntax for closing a service with rmtool.exe, but I'm not sure. I'm running rmtool.exe from an admin command prompt. the test case says to use "rmtool.exe -f $dir|<service> -S" so I have tried different combinations, but the only time rmtool.exe seems to see the service process is when I use the executable file path, where I get this output: C:\folder> ...Show All

  This is incredibly minor, but are there any plans to add HLSL Syntax Highlighting to XNA Studio Express Shaders aren't going away for a while, and it would be quite useful to have some syntax support in XNA. Hang on a minute, shouldn't those of us who have shelled out a fortune to get the pro version of VS2005 get that first Seriously though, it is about time that feature was put back into VS, along with the long lost shader debugger.

• Visual Studio 2008 (Pre-release) Why BitmapEffects are Slow ?

  Hi! I want to make a photo gallery application that displays the groups of pictures like Phodeo. Each group is composed from a grid which contains a ScrollViewer and a TextBlock to show the name of the group. I want that around the grid a shadow to appear, so I use the ShadowBitmapEffect. What I found is that animations are very,very slow when I use the BitmapEffect Why Aren't the effects rendered in 3D And another question: which is the better way to modify, for example, the size of an object. It's better to set manually the properties (Width,Height), or to use a ScaleTransform Thank you! BitmapEffects are always rendered in software, and force whatever they apply to to be rendered in software, hence t ...Show All
