• .NET Development Folders on website

  When I create a webform using VB.NET everything works fine as long as I upload my form to the wwwRoot folder, but when I create a folder in the root directory and then upload the webform to it, I receive a generic error message, "Server Error in '/' Application" Any suggestions will be greatly appreciated. Thanks for replying. The site that I'm uploading to is StartLogic.com (a web hosting service, etc). They have a web-based interface to the IIS engine and I have made the folder a virtual directory, but there is no option for me to assign a version of the .net framework. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. HLSL lighting

  I am using pixel shader for lighting. I have a questions about computing different lights (directional, point and spot) and their components (ambient, diffuse, specular). What I am currently doing is I compute all of the lights and their coponents seperately, then I add the components for each type of light. So I have a diffuse, ambient, and specular colors for each type of light. First question if I have two spot lights at two seperate points after i compute the diffuse, ambient, and specular for each light do I just add them together and divide them by two. If I do that then they lose some if the power then if I just had one light. My second question is how would I put the different lights(directional, point and spot) together. What i' ...Show All

• Visual FoxPro FoxPro 6.0 not using CodeBase Index

  Hi, I'm creating a table (.dbf) with and index (.cdx) a driver : deBaseOdbcStandFoxPro. I'm using this driver because with after creation i'm using some optimize insertion of code base to the table. after that i'm closing the table and the connection to the data dase, and opening it with "Visual FoxPro 6.0 ODBC driver" to perform querys. My problem is that the the visual foxpro driver isn't using the index i created (a query takes the same time with or without the index). i asked codebase what seems to be the problem and they said that there files are foxpro compatible and that i create the index correctly and the problem is probably with microsoft driver and maybe it's because foxpro allows deleted records. does a ...Show All

• .NET Development Dotfuscator 3.0 doesn't work

  I obfuscated my Pocket PC application. I do not use reflection and couldn't find an reason in the documentation why this should not work. I run the app and the main grid doesn't even fill. So then I tried turning it off for forms, but it ignores me and obfuscates everything anyway. There is no forum or support on this product, so I am at a loss. I can't find anywhere where it talks about this specifically. Any ideas Are you talking of the Dotfuscator 3.0 by Premptive Did you try their support page http://www.preemptive.com/support/DotfuscatorSupport.html ...Show All

• .NET Development Memory leak in SerialPort.Read?

  Hi. I communicate with the serial port on my ”PDA/smart device” to another device (custom circuit board). The PDA needs to send data at least once a second to the hardware just to confirm that there is a connection; If not the hardware shuts down. The PDA also receives information from the device witch is displayed. The problem is that when the PDA receivea data, the application starts to leak memory. After 30 minutes to an hour the garbage collection procedure takes so much time that the communication halts for several seconds, witch in turn causes a timeout. Could there be a problem in the SerialPort.Receive() or in the garbage collector. Most likely I have done something wrong… Here is a simplified ...Show All

• SQL Server Flat File With Fixed Length Header and No Delimeter

  Hi, I'm trying to extract data from a Flat File which is as fixed length as they come. The file has a header, which simply contains the number of records in the file, followed by the records, with no header delimeter (No CR/LF, nothing). For example a file would look like the following: 00000003Name1Address1Name2Address2Name3Address3 So this has 3 records (indicated by the first 8 characters), each consisting of a Name and Address. I can't see a way to extract the data using a flat file connection, unless we add a delimeter for the header (not possible at this stage). Am I wrong Any suggestions on possible solution would be much appreciated - I'm thinking Ill have to write a script to parse the fil ...Show All
