Hi there,
I need some help of changing extensions of files..
My code so far is:
<br />
string filename = Path.Combine(@"C:\Test.txt", @"C:\Test.txt");<br />
filename = Path.ChangeExtension(filename, "old");<br />
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
Best regards

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"));

Thanks Robert,
this is the code i used and it works perfectly
<br />
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...
Regards

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'm fairly sure that it is impossible to write a driver in C# at this point. Check the C++ forum instead.

Hi,
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?
thanks!

Hey tecchies,
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.
Any views/experiences would be welcome.
Thanks
Regards,
Rob Philpott.

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.

you can use the selectedcell property of the datagrid to get
the data within a particular cell.

Depending on how safe you want your license to be making it yourself can be very complicated.
There are several commercial components which do what you need. One of them is this[^] on.

I have developed an windows service in C# the working of service is to fetch data from database generate some messages and store those messages in database.
The problem i am faceing is the memory consumption of my service is very it goes upto 2GB and due to this the system hangs.
I have disposed all the objects and also i am invoking garbage collector after
specific amount of time but the memory still increse.
The service is running on Windows-2003 server.

You're missing something somewhere. You're going to have to profile your code with something like CLRProfiler to get its memory consumption.

You just about NEVER have to do this. Did you know that your entire application, ALL of it's threads, come to a complete halt when the garbage collector runs? Still think this is a good idea?

I have already profiled my code using .Net Memory profiler, Ants profiler and also CLR profiler
and changed my code according to the results of above profilers.
Is there something another way by which i can come to know which objects are in memory and not getting disposed

The CLR Profiler will tell you, if you know how to read it.

Have you checked the source of the page? What id does the dropdown get?
If you moved the dropdown inside a container, the id can change.

b { font-weight: normal; }
