• Software Development for Windows Vista Installing SQL 2005 on Vista

  Hello folks, I have just installed vista and the next step is to install other software for developing applications on vista. While trying to install SQL 2005 i get an error message which says that i dont have enough previleges to use IIS. And as a result i am not able to install an important part of SQL i.e reporting services.

  I am writing an application for a Windows Mobile device using C# and .Net Compact framework. I need to obtain the system timezone or timezone that the user specifies in the Settings/Date and Time area.

• SQL Server Interactive Sort - in Descending order by default

  Interactive Sort is used heavily in our "wide reports" (tabular reports with many columns). Naturally for some financial values, higher values carry more importance. We now need to achieve interactive sort in DESCENDING order by default, i.e. upon first-time clicking on the column header, the report is refreshed with data sorted in descending order of the selected column. (Without this, the users need to click twice to achieve the desired result) For numeric values, this can be done easily by using = - Fields!Count.Value as the interactive sort expression. The problem is with "text" data. We thought that using asc() or ascw() to first convert the text to numeric could achieve the same effect, only to realized ...Show All

• Visual Studio Express Editions GetAppDomainByName()

  Why doesn't .Net Framework provide a method GetAppDomainByName() to get the AppDomain given its friendly name This would be extremely helpful in making calls to other domains. Thanks for the answer. But I was asking about AppDomain and not www domains. Once we enter another AppDomain, we do not have a way to call into a particular AppDomain. That's why I asked this question. ...Show All
