• sifacomp A question of OO structure...

  Hello All, I'll do my best to explain what I'm trying to accomplish and look forward to any and all suggestions you have for the "proper" way to do this (realizing there is no 100% correct way, but some methods are more optimal than others). I apologize in advance for my n00bness. For this example, I'll use football (american) players. I want my Player class to have a List<Stat> collection of my Stat class. Each Stat, which is an indicator of how well a player plays a particular position, should have a base value but be able to return a "true" value which is a calculation of the base value plus a percentage of one or more other stats. For example: a Player's Halfback stat might be base value plus 50% of the Fullba ...Show All

  I have a datatable and when i add the rows to it....I click my OK button when i click my OK button I add all the rows to an arraylist...then i loop thorough my arraylist and insert the values into my database.....How would one go about getting those values out of my database back into the arraylist and back into the datatable....I know how to put it in the database but i am kinda cloudy on how I would get it back out and into my datatable....any help with this well you would use a SqlDataReader to read the values back 1 by 1 and store it into an arraylist. But you are better off using a SqlDataAdapter to fill the dataset/datatable with values and update the database when you change values in the dataset/datatable and avoid the who ...Show All

• Iram smtp client/server for password recovery, logins etc

  Hi all, Just found this forum tonight so I hope I'm posting in the right place - I didn't see any other topics that seemed to relate to my problem. Firstly, I'm a rookie with this stuff!

I cannot seem to set up the server to send emails. I have options in for members to recover their password, change password, etc. However, when the user fills in the boxes and clicks submit, an error screen comes up to do with the email/smtp.

• Davids Learning unsafe code compilation in Visual Studio.NET

  hi there ! I am extreamy new in vs.net and I can not compile the unsafe code through VS enviornment , there must be some thing for that but I dont know how thanks To add a little bit to what Mattias said, you can open the project properties by either double-clicking on the Properties node in Solution Explorer, or by right-clicking on the project and selecting properties. The option is "Allow unsafe code" and it appears on the Build tab of the properties that open (it's the 3rd checkbox on the page). Hope that helps! Anson You can include /unsafe in the compilerOptions attribute in the <compiler> element in web.config. [Moved post to the C# IDE forum] Yes you can enable use of unsa ...Show All

• AdeptBlue Disposing singleton class

  How should i dispose a singleton class Lets say you have many forms that have a singleton instance (singletonclass implements IDisposable). ie public class Form{ private SingletonClass instance = SingletonClass.GetInstance(); } id like to know when the singletonclass should be disposed Should I keep a counter in the singletonclass and then check when the counter hits 0 (when a form disposes, it decrement the counter of the singletonclass), then called dispose of the singletonclass But that seem not really secure. Cuz i mean .. in a class .. you could call SingletonClass.GetInstance() as many time as you want .. and the counter will keep incrementing, but only one form is having the instance of the singletonclass. Thanks, ...Show All

• Leebert Loading Class library dll

  How to load a .net class library dll dynamically from a .net windows application using vs 2005. Hello, Look at Assembly.Load function. Then to create an instance of a class from your library, you can use the CreateInstance function: object theInstance = assembly.CreateInstance( "MyAssemblyNamespace.MyClass", true, BindingFlags.Public | BindingFlags.Instance, null, null, null, null ); Richard Loading DLL dynamically at runtime is achieved through Reflection. See System.Reflection namespace and better search some article on google about Reflection. I hope it'll work. Cheers ;) ...Show All

• Ro0ke Creating a Wizard-Style Application

  My current project is to develop a wizard-style application, with next, back, cancel, etc. I'm running into a problem with how I should implement the wizard. My first thought was to use panels for each step, but this quickly became overwhelming when I had 30 panels of the same size, all on top of each other. I had to use Send to Back repeatedly until I got to the step that I wanted to work on. My next thought was to use separate forms, but I don't like this approach very much either. I would have to copy over the elements that stay the same on each step (the navigation buttons) to each from and line them up. This takes too much work. Lastly, I thought of maybe making my own control, similar to a tab control, only the ...Show All
