Looking for a way to update a Sharepoint ListItem by using the Lists.asmx webservice... For doing this you need to create your function to create your Xml Layout and afterwards call the function below UpdateSPList.
strBatch containing for example:
Remark: The next Chars must be translated in the text values for your Fieldtag: "&" ==> "&" "<" ==> "<" ">" ==> ">" "\"" ==> """ "'" ==> "'" Below you find my Function that I have created that actualy does the update or insert into your List. It requires three parameters : - the Site Url you are working on - the List name on which you want to add or update one or more items - the XML that contains the Batch Element You will see that the function also uses the next global parameters - sTechnicalUser - sTechnicalPw - sDomain - bDefaultLogon (if true you will connect to the webservice with the user that is executing the program, otherwise use the technical user with it's password and domain. This is done for giving the possibility to let shedule the program.
