• .NET Development StringBuilder.Replace

  My app reads text files and verifies the daa before it is processed. If a field is invalid, the app will note it and either space or zero out the bad data. The user will take the information and manually correct any incorrect fields.

My code is below. strInputText ... : Input file strHoldText ... : Holds the field data strTempText ...: StringBuilder variable The CheckIt method returns the changed data field, however; the field in the input record is left untouched by the Replace method.

• Software Development for Windows Vista Black Screen / Freeze after first reboot

  I have spent many hours the past week trying (unsucessfully) to install Windows Vista. I have downloaded and installed all the most recent drivers and BIOS updates for all of my hardware. I have run the Vista Upgrade Advisor and it says that my system should be good to go and that there are no serious issues. The only item on the "Task List" is to download Vista drivers for a wireless networking adapter I have in the system to be installed after. I have tried to do an upgrade from Windows XP and a Full Install of Vista with the same results. I start the install and everything goes smoothly (installer unpacking files and getting ready for installation) until right after the first reboot.

• .NET Development Server connection timeout

  Hi guys, I am using the code below to connect to a server. This works fine on all the machines I have ever tried to connect to but a new server has recently been added on which it seems to timeout randomly. It would normally take 8secs to connect & retrieve information from a server but this takes 2 minutes on those random occasions. I believe that it may be the server timing out & responding a bit late as it might be busy or something.How could I possibly work around this and find out what is wrong I am using a third party SSH library to connect. I would appreciate any help StringBuilder output = new StringBuilder(); //SSH connection from 3rd party library (SSH2) //SSH Reader from 3rd party Socket s = new ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to get amount of free/total local video memory?

  Current properties and methods (HardwareCaps.VideoMemoryTotal, Device.AvailableTextureMemory in April 2006 SDK) are returning local+nonlocal amount of memory. Is any way in MDX how to get amount of local video memory only Thank you, mikrogen Not through Direct3D - micro-management of such resources is left to the driver (as well as being a non-trivial equation anyway) and the application developer doesn't really need to know any more specific information.

A lot of them are twisted and distorted by marketting departments just to beat the rival... I've not personally tried it, ...Show All
