• Preposterous .Net 2.0 Installation Problem

  I have installed .Net 2.0 on my computer however my projects within Visual Studio 2003 are still using old system dll versions of the .Net Framework. How do i tell it to use the new .Net 2.0 Framework. VS2003 does not use 2.0. There is no way to make it do that. You need VS 2005.

• ian_gaydos Using System.Net.Mail class to send mail.

  Hi, I was coding a class to send mail via SMTP, but I found that in Framework 2.0 you have System.Net.Mail to do that task. The classes works fine to send mail on a server that does not require authentication. Unfortunatelly, I can't get it to work on a base64 encrypted server. The process of logging in that type of server is easy, so I expect an bool attribute, let's say, "IsAuthRequired", but it does not exists. From what I've ...Show All

• Bigby ExtendedDN usage?

  I'm having a problem using the new ExtendedDN enum introduced in the 2.0 framework to return objectGUIDs as strings.  Previously, they were returned as octets, which had to be manually converted to a string.  The new ExtendedDN enum is to make life a little easier. :) I'm using .NET 2.0 beta 2. Here's the MSDN info on ExtendedDN: http://msdn2.microsoft.com/library/ec42w73t(en-us,vs.80).aspx string struser = "jdoe" ; DirectorySearc ...Show All

• SLeGendre NullReferenceException when calling PerformanceCounterCategory.Exists(categoryName)

  I am experiencing an odd error in one of my applications where I randomly seem to see NullReferenceExceptions when I call PerformanceCounterCategory.Exists() with a non-null category name.  I am working with version 1.1 of the .NET framework. I have verified that passing a null or empty category name would generate a different exception, so I am pretty certain that the problem is NOT that a "bad" parameter is being passed to this method. ...Show All

• allan.taruc Values of sizeof concerning struct (no optimization?)

  I have been playing a bit with the sizeof operator, and the results that I get seems not too good. For example, let me consider struct Zero { }   an empty structure. With .Net 2.0, I get sizeof(Zero) equal to one. I know that such case is borderline, but I would like to understand why it's not zero (I do not see why a zero-length LValue should be a problem), Also, let me consider again struct SomeBits { bool a; bool b; }   ...Show All
