• .NET Development RSA Key Container stored on hard drive?

  I have a question about RSA key containers. In the following code, a key container is created and passed to the RSA CSP. Every time the RSA CSP is initialized, a new key is created. MyCp = New CspParameters MyCp.KeyContainerName = "My Key Container" MyCp.KeyNumber = 1 'new key created here MyRSA = New RSACryptoServiceProvider(1024, MyCp) Is the key stored on the hard drive somewhere Can I close the app and restart it and access the key which was maybe stored on the hard drive. So far I have been unable to use a key container once the app has been closed. I suspect the key container is stored only in memory so it disappears once the app has been closed. Is this correct In the event the key container ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 360 Boat game with source

  Hello I was playing about again the last 4 days and come up with a little boat game for the 360. The source code is very untidy but there might be something of use in there for some people. It was written for use on the 360, it might work ok for the PC. You can have 1 to 4 players and it uses some ai for the others. There's only 1 track at the moment - I may get around to fixing it all up into a proper game if there's enough interest or if an artist wants to help out. It plays a different sound effect when you cross the line and beat your own best score. My best lap is 8.07 (no down to a 7.96) seconds.   Best to use a 360 pad but here's some keys if you feel the need.   Q and E change the number of players ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Numeric performance on 360

  A question for the framework/VM guys... I have ported one of my simpler benchmarks to the 360, and find that the numeric performance is running 5x slower than my 2.8GHz P4 desktop. Now I was expecting a drop in performance on the 360, allowing for the difference in CPU implementation (in order execution / branch prediction etc), but nothing like this magnitude! The benchmark simply transforms a source array of Vector4s to a destination array of Vector4s, using a 4x4 matrix. Have you guys done any benchmarking of pure numeric perf, and if so is this in line with what you get Andy. Okay, some hard numbers from my game. Basically, I'm decoding some data, creating meshes from some previously-loade ...Show All

• Windows Forms DataGridViewImageColumn new row image

  I have a DataGridView - the first column is an unbound DataGridViewImageColumn.  The purpose of the image is to allow the user to click the Image - go to "lookup" form - select data - come back - and it programatically fills out (most of) the new row - based on what was selected in the "lookup" form.  I s there a way to replace the 'null image' (box with an 'x') with my image for "lookup" (binoculars in this case) in the row being added     An easier way you can do this is specify it to be null on the RowsAdded event as specified here http://msdn2.microsoft.com/en-us/library/system.windows.forms.datagridviewimagecolumn.aspx ...Show All

• Visual Studio Team System BVT's without Team System Tester Edition - Possible?

  I'm trying to create a Team Build that will run all my unit tests as part of the build. The problem is though, when going through the wizard it allows me to select the vsmdi file, but there is no test lists available in the drop-down (and since I don't have team tester edition I don't think I can create new test lists). We can still run the tests in our Team Software Dev Edition, is there a way to make a Team Build that will also run all the tests as part of the build process without purchasing Team Tester Edition Can somebody provide some details about how we specify a .testrunconfig file if we are no longer using a vsmdi Do we still need to use a vsmdi file in a <MetaDataFile> element in addition ...Show All

• SQL Server Server options are not being executed from local programatically code??

  Dear all, For example, executing a DTSX stored in a server, execution is fine and successfully but the log file attached to that DTSX is not created at all after the execution. Otherwise if I'm going to execute from the server everything is fine: log file is created and gathering the usual information. Let me know if exists any option for to enable this from the own DTSX. If I run local packages log files are created without problems. Thanks in advance, No. What is the path to the file I'm trying to determine if its a UNC: \\MyServer\Myfilelocation\Myfile.log or a local path: c:\Myfilelocation\Myfile.log -Jamie ...Show All

• SQL Server SSIS Excel export with 64-bit version

  I have a problem, and I'm fairly sure I know what the answer is going to be, but I'll ask it anyhow. I have a database which I switched over to SQL 2005 last year, and in the process converted all the DTS packages I had to import the data over to SSIS. We have several reports that we generate to Excel files, and I attempted to migrate these over also, but they would never run in production. Worked fine in when I developed the packages, but nothing I did would make them run in production, so I droped back and punted by modifying the DTS packages to point to the new database. Everything works fine that way, but we want to retire the old SQL box. When I started digging into the problem by running the package from the dev platform on the ...Show All
