If I was to upload one or more file(s) to a server, is there anyway to check that / those file(s) against the file(s) stored on my computer without downloading the file(s) to check against the original file(s)using VB.Net?This would need to be done in a recursive fashion from a parent folder downwards, the folder being of the end-users choosing.

Is it possible for my application to check if its been modified?
e.g. Could i compile the app and use a 3rd party tool to calculate the MD5 checksum of the compiled exe - and inside the app, code it so that if the MD5 checksum doesnt match then run the deactivation process?
I know its not foolproof but if it makes it slightly more hassle to crack my app i'd rather have it

View 21 RepliesI have an MS Access database and an MS Visual Basic 2008 front end.I get this error when trying to update a record that has related records:The record cannot be deleted or changed because table 'X' includes related records.I only want to update one field in the row in the 'parent' table which is not the primary key field of either record but the 'Update' command seems to want to rewrite the whole datarow. Rewriting the whole row causes the error (as this updates the primary key). If I switch off refrential integrity checking in the underlying database this solves the problem except that I want to maintain referential integrity so its not really a solution. I have tried beginEdit and EndEdit with no success - same error.Is there a way to update just one field in a row and write that back to the database?
View 2 RepliesI would like to determine which DataGridViewRow causes an SQLException to occur.A typical scenario follows:1) Using LinQ, I select a set of 'StockItems' as a datasource for a datagridview, and all works fine.2) I insert a new object and (purposely) leave a primary key value blank.3) I attempt to save using MyDBContext.SubmitChanges(Data.Linq.ConflictMode.FailOnFirstConflict)4) An SQLException is received.How do I tell which row has caused a violation, particularly when one or several changes have been made. I would like to advise the user that a specific row in the datagrid caused the error to occur.
