RE: Checking to see if a document library has CheckOut set to on

Hi Peter,
You can checkout the document library by using following code:
if (item.File.CheckOutStatus == SPFile.SPCheckOutStatus.None)
{
item.File.CheckOut();
}
But the problem with above approach comes if you have enabled versioning on
document library.
Though your item gets updated successfully but it will create a new version
for the updated item in doc library.
Workaround for above versioning problem is:
item.SystemUpdate(false);
Do remember to set SPweb object AllowUnsafeUpdates property to true before
doing item update.

Hi all,.
I have some code that trawls through all document libraries and adds a new
field to it. It then fills in a value for all documents within the library.
The code works fine until it hits a document library that requires the
document to be checked out and then in crashes
Now I may have done this the wrong way (I have used SPItem instead of
SPFile) but I need to be able to check to see if the document needs to be
checked out or not and am struggling to sort it out quickly.
The application accepts two parameters, the site collection URL and then a
switch (/run, /norun and /backout)
Here is my code...
