the filename variable does equal C:\Test.old but it never actual changes the extension in windows "explorer"...
i tried so many different ways but always get stuck with this problem..
Please help thanks
The functions you are using are just helper functions for correct string manipulation.
You should use either File.Move(filename, Path.ChangeExtension(filename, "old"));
or new FileInfo(filename).MoveTo(Path.ChangeExtension(filename, "old"));
this is the code i used and it works perfectly
string filename = lboxFiles.Items[x].ToString();<br />
new FileInfo(filename).MoveTo(Path.ChangeExtension(filename,cmbxRenExt.SelectedItem.ToString()));<br />
One question though,if i use the MoveTo isnt it bit slower than actually just renaming the extension because now it moves over replacing every file?
the reason im asking is because i have to scan and change over 500000 file extensions lol...
Thanks for ur help i really appreciate it...
Move is intelligent. As long as you remain on the same drive Move is not really moving all bits of a file but is just changing an entry somewhere in the file system. It's like in Explorer. There you can also 'move' files between directories with nearly no time loss.
But 500000 will nevertheless take some time probably.
I have been asked to investigate the possibility of writing a "virtual printer driver", so that we can distribute to our customers to enable them to print-to from any third-party software and allow us to generate an XML file output with text and some "information" about some graphics!
If anyone can direct me towards either some URL's or books etc, that can assist in the development of printer drivers I would be very appeciative of them Any advise on the matter would also be appreciated, especially if you have written printer drivers before.
I want to add a spell checking textbox to a c# project I have, is this possible? I have all the relevant software (WinFX runtime, extensions for VS2005 Express etc.) but there is no way to enable the textbox.IsSpellCheckEnabled property I have read about.
Is it possible to make a custom WinFX control which is a spellchecked textbox, then add that to my project? If so is there any documentation on how to achieve this?
For a project I'm working on that moment, we need to create a new database in Sql Server 2005 (to make use of the native xml datatype). One of the things which seems to be plugged a bit in 2005 is the use of managed code stored procedures.
Has anyone had any experience of writing and using these? Can you advise on their advantages and of any difficulties you may have encoutered? I'm no database expert, but I would have thought that they would lack the 'execution plan' which standard stored procedures provides. In fact, I can't see a great deal of point of this new technology.

There are many things you can do with C# that you cannot do in SQL, or is very difficult in SQL.
As Microsoft have said on countless occasions, CLR integration in SQL Server does not mean you can ditch SQL and replace everything with C# code. The CLR integration is for doing stuff that is difficult or impossible to do in SQL directly. It can also be used for creating custom types in SQL Server.
For me, I've not yet tried any of this yet. I'm waiting until I hit something that is obviously crying out for CLR integration to make it run great. However, I've not found it yet.
