• Smart Device Development SerialPort locking up after device On/Off

  I have an issue similar to this to Re: PocketPC SerialPort and turning off/on the device I have a i-mate PDA2K talking via bluetooth to a Destron DTR1 Every thing works correctly until the PC-device is turned on/off (automatically or manually) When the device powers back on I get two PinChanged Events CtsChanged and DsrChanged as happens when the connection is first opened.

• .NET Development How to update/insert/delete from mulitple tables with SqlDataAdapter?

  My datatable is a composite of two tables so I have to write my own insert, update and delete SqlDataAdapter commands. Since the datatable is a composite I need to affect 2 tables when the adapter updates/inserts/deletes. How to write these commands to affect two tables   You can write two separate INSERT/DELETE/UPDATE SQL statements and separate them with semicolons, or use a stored procedure with both statemens inside. I prefer the first method because I can easily write code that works on almost any SQL database, but anyone on the "cult of the stored procedure" will send you the ot ...Show All

  Hi I wish to get hold of the clients IP address, mac address and computer name within a service that is exposed using a net.tcp binding.

• Game Technologies: DirectX, XNA, XACT, etc. Dramatic memory leak in DrawText

  I've been banging my head against the wall for the last few days trying to track down the source of a rather big memory leak in my Direct3D-application. Turns out the culprit seems to be the DrawText function. Let me explain exactly what happens: I'm using a variable width truetype font (Times New Roman) created through D3DXCreateFont. I'm using this in various parts of my application, but the part where the problems are easiest to notice is in my custom UI textboxes. I use a function called InsertText to add new characters to the printed string, and everything I initialize is cleaned up properly afterwards. The problems only truly beg ...Show All

• SQL Server usability issue - open .sql files via visual studio

  I'm on a dev team using Visual Studio 2005 and Visual SourceSafe 6. Our solution includes all of the SQL DDL scripts in a set of script files in a folder in one of the data tier projects. This effectively brings the Transact-SQL under source control and makes it easier for us to work with it in a shared environment. There are about 100 .sql files, each concentrating on a particular part of the database. I use the SQL Server Management Studio to edit these scripts, generally opening it by double-clicking on one of the files in Solution Explorer in Visual Studio. The issue I have is in regards to opening multiple files. Does anyone know of ...Show All

• Visual C++ unable to edit command line for a project
