CultureInfo .CurrentCulture.ToString(); The output of WinForm is “ 28/11/2006 11:03:21 en-GB ”, while WebForm is “ 11/28/2006 11:02:55 AM en-US ”.

• chris441962 Why the following condition is never met?

  double number1 = 1, number2 = .5; while (number1 > number2) { number1 -= .1; MessageBox.Show(number1.ToString()); if (number1 == number2) MessageBox.Show("condition met"); // <- never } Please help Floating point math isn't 100% precise, especially depending on the granularity of the decimal places or in cases where both numbers vary greatly. In this case, number1 might be 0.5000000000011, which is not exactly equal to number2 (0.5). It's a classic issue with using floats and doubles. So your choices are to avoid using "==" (use some variation of range checking instead), or use a fixed point datatype like decimal instead of a floating point datatyp ...Show All

• matti-81 What are Generics? what do I get from them?

  If anybody can provide a sample code, much better. Thanks, Omar generics is new in .NET 2.0. It allows you to make a safe strong typed collection and allows you to use them similar to say an arraylist such as adding/removing objects. you can only store objects of a certain type in this collection and nothing else, otherwise you will get a compiler error List<string> theStringCollection = new List<string>(); theStringCollection.Add("hi"); //correct theStringCollection.Add(1); //compiler error - because its not a string. it has to be a string because thats what the collection type is. another example, if we have an class called "person", we can only hold objects that are o ...Show All

• Bravechou Embedded manifest in .Net App

  How to make someapp.exe.manifest file embedded in someapp.exe In C++ application we could set manifest using manifest tool. I don't want to have separated from main application .manifest file. I've added manifest in C# project, but there is no special settings applied to manifest files in VS2005. The only option I've found useful is Copy to output directory -> copy if newer. I'm not sure what you mean. If you're talking about the Assembly manifest then that is embedded in all C# applications. You can't *not* embed it. You can access it using the System.Reflection namespace. This is simply not true. In my experience the manifest is not embedded automatically. Accor ...Show All

• saAction NullReferenceException was unhandled.

  I was sending a pictureframe to a client in synchronous mode which meant, the program gets blocked until the client is found or transfer is complete. Consequently, I shifted to asynchronous mode. Now as far as i can see, there's nothing wrong with the client/server bit of the code but the part, where I am copying the picture frame from a clipboard throws this exception. It's utterly preposterous ! Apparently NOTHING gets copied from the clipboard and the IDataObject ends up having a null status. This never happened in the synchronous communication mode, hell, i didnt even touch the frame grabbing portion of the code. Anybody know whats wrong Most probably you check clipboard BEFORE data is copied. ...Show All

• anubisascends Save my program for God's sake!!!!

  Just as I was getting some decent work done on my project, I set down my keyboard to make a bathroom run, and once i returned, I found my cat lying on my keyboard...

• Bollwerk How to call .NET 2005 assembly from .NET 2003?

  Sample source code will be great. Thanks I have an assembly made by VS .NET 2005. I am now using VS .NET 2003 and I want to call the DLL written in .NET 2005. Hi, cl408e I'm confused whether you are dealing with VS2005 now and wanna call assemblies from VS2003 or in the opposite way hi, It's ok for you to call assemblies of Framework1.1 (VS2003) in Framework2.0 (VS2005). But Framework2.0 has some break changes from Framework1.1, it cannot be compatible forward, since may touch the break changes. Thank you ...Show All

• Ian Jorgensen CheckBox and CheckBoxList?

  what's the difference between CheckBox and CheckBoxList in a webform could anyone here give me a example for both many thanks checkbox is used for a single value selection. say for example the contact and permanent address are same, so we can use single checkbox to get the information from the user. whereas Checkboxlist is used to get the group of informations from the user, means multiple checkboxes with the same name. so no needs to write such a long coding. just simply using the for loop we can get all the checkboxes values. example for Checkbox <asp:checkbox id="check1" runat="server"  value="Same as above"/> this.check1.value is used to get the value example for Chec ...Show All

• Koen Vermeire Generating all possible character combinations

  Hi everyone, I just wanted to know if you have better ideas on generating all possible 4-character string combinations in C#. Something like: aaaa aaab aaac ... zzzz What i have in mind right now are nested for loops. I wonder if there is a .Net function for automatically incrementing characters/string. Thanks a lot. -Ver Look at using the StringBuilder class. It has a Chars property with an indexer that will allow you to change each position. You will be able to use a single StringBuilder object, although you will be creating a large number of strings at some point. Consider using SQL Server to do the work for you.
