1
2

crow is 1, not 2.
Am I missing something here?
2. How do I know whether certain rows are modified in datagridview?

View 2 RepliesFiles Not Being Created / Deleted
Jul 30, 2011I have an app where a user enters information on a ticket and that ticket is saved off to a file on a share.Later on, when the ticket is closed or resolved, the file is deleted.Pretty straightforward.The below code is used to achieve this but, and this is the odd part, I'm finding that sometimes the app does not write the file and other times it will not delete it.I've confirmed that the user is running the latest version, that the tool isn't in off line mode, that all the appropriate criteria are set to true before entering the routines. It works 99% of the time but every so often it doesn't create/delete the file and there are no errors thrown or anything.Going into this section of code, chkOffline is not checked, "GoNoGo" is set to "Go", "Type" is set to "Live" and all fields have been filled out on the form(and vetted).What's more, there are other actions earlier in the app/sub that rely on these same conditions and those actions are getting carried out.[code]

If using FileSystemWatcher component, I cannot get the files being deleted because it will only notify after the file is deleted.

Cookie Being Deleted Unexpectedly By Application
Jan 26, 2010I am having an issue with a cookie that keeps getting deleted by the application. When you go into the application, if the cookie does not exist, it gets created. This works fine and everything in the cookie is stored correctly. When I click on a link to go to another page, once everything loads completely, the cookie gets deleted from the file system. Even stranger than that, the values from the cookie remain until the browser is closed. That is the application appears to be retaining the values even though the cookie does not exist on the local file system. The next time you enter the application, the cookie is recreated so any values stored are lost.Now, I have done some tweaking on the code to see what could be causing it. I found that I am adding the cookie to the Response object any time I make a change to the cookie. The cookie is also being added to the Response object when the page load is completed. My initial thought was that adding the cookie multiple times to the Response object could be causing the issue. I commented out the code in the page load complete event and the cookie hung around until the next postback. Then I put in some logic to keep the application from putting the cookie into the Response object more than once, and then I lost the cookie again at the same point as before.All of the code for handling cookies is in my "base page" that all pages inherit from. The page that seems to be loosing the cookie is my search page. I am including the code from both of those pages.[code]
