• Architecture O/R Mapping

  O/R mapping is quite interesting.  I would like to post this question for discussion. I have the following classes: Employee, FullTimeStaff, PartTimeStaff, etc.  FullTimeStaff and PartTimeStaff have many attributes and behaviors in common and also many other unique attributes and behaviors.  So, FullTimeStaff inherits from Employee and PartTimeStaff also inherits from Employee. Do you think it is good to map both FullTimeStaff and PartTimeStaff to a single table called Employee (the table contains an extra field to identity whether he is full time or part time) in the database I have a table keeping all FullTimeStaff and PartTimeStaff and we also have a StaffType field to classify them. I have a staff ID to get a ...Show All

• .NET Development Application Settings

  I created a Windows Service which has a Settings.setting file with several parameters. I also created a Setup project which accepts several parameters. These are then updated to the config file that stores the Settings.setting parameters. When I debug the setup I can clearly see that the parameters (custom ones) are written to the config file. But when starting the service which happens after manipulating the config file, the default values are retrieved using Properties.Settings.Default.<ParamName>. I must be forgetting something... Anyone have a suggestion Hello All. Steven: I'm having my own case of brain fever with application configuration, so I figured I'd try to lend a hand. So far, ...Show All

• Smart Device Development Getting SSL, Web Services, and Mobile Devices to connect.

  I have written a web service that is running on a windows 2003 IIS instance with SSL enabled. I am trying to determine how to get the mobile device to connect with the web service.

• Visual C++ LNK1181: can't open it's own .obj as an input??

  I have this one project that is part of a larger "solution" with many projects. I am using VC++ 8. When I try to build it from the command line, as: msbuild MyProject.vcproj /p:Configuration=Release ... then it fails on a linker error: LNK1181: cannot open input file '.\Release\MyProject.obj' (the project contains a MyProject.c and .h file, so that's why the object file is named the same) However, when building from in the IDE, it builds fine. This object file is created as a result of building this project. Why is the linker looking for it as input I checked all the project linker settings and can't find a mention of that object file anywhere, which is as I expected since the IDE builds it fine. I know ms ...Show All

• .NET Development IsolatedFileStorage and Saving/Loading

  I would like some resources or information on how IsolatedFileStorage knows where to save or load files from... The problem I am having, is that we are using IsolatedFileStorage to save application settings. So it is using machine storage. We do not use ClickOnce deployment, however we are going to be using dotfuscator on the final EXE we ship. I noticed the other day that settings I had saved in the non-dotfuscated EXE would not load in the dotfuscated EXE. I would imagine that this is because the main assembly was renamed. I also noticed that the settings wouldn't load if the folder the EXE was located in was changed. Is there a way I can make our EXE file use the same IsolatedStorage folder whether it's dotfuscated or not, or no matter ...Show All
