How To Create Audit Trail Of Record Changes In A Form In Vb Net?I get the NewValue from the changed property but how can I locate the OldValue for date/time pickers, text boxes, check boxes are the main items on the forms.
View 1 RepliesI was hoping that the various controls for WinForms in VB.Net 2008 would have a property such as OldValue and NewValue that I could pull from the Change property.
I'm wanting to write a generic code that will save the OldValue, NewValue, name of field and name of table, and date of change directly to a simple Audit table.
Items aren't changed often, but we need to be able to trace the history of changes to certain fields. I've got the code written for saving to the table, but I'm not finding anything that will show me the two values I need.

I'm trying to create a 'trial version' for a software of mine, currently it is pay-only. Basically the most efficient way I can think of is to simply change the startup form of the trial version after 15 days. The new startup form will simply be a request to register.
-How can I change the startup form after 15 days?
-How can I ensure that this cannot be changed afterwards (so it isn't easily pirated).
I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

View 16 RepliesI've got an application that takes the files in a folder structure and publishes them to another location. Currently it goes through every folder/file and compares the dates in the source and destination. If the file doesn't exist in the destination, or is older, then it copies it across from the source. It's obviously foil proof, but not as fast as it could be.
Ideally, I'd like to create an audit (or audits) saying what the current state of play is in the destination and compare the source folders/files against that instead.
This of course assumes the destination isn't messed around with manually, but I think that's a fair limitation.
So has anyone got any suggestions for how this audit could work? ie: How I could store data/values, such that on the next run when I look down the source folder/files I could compare it to the audit and see 99% of the files are unchanged, so only send across the X new ones etc?
ps: I don't suppose there's a valid (in Windows) that can tell you the date any file in a folder was created/amended? ie: So rather than checking down 200 files to see their individual dates/times, if I could get a single folder level value saying the date of last update/create, if it hasn't changed since the last run, there's no work to do! There is GetLastWriteTime but this doesn't seem to get updated if you amend/update a file, rather than creating a new one!
I have a winform which allows people to edit data from a database, to simplify things assume there is a Customer table in database with 3 fields - Name, City, Country. Through winform(s) people can Add/Edit/Delete customers.For each of these actions we need to save:
What the field names are (Name,City,Country in this case)What the field values were before they were modified What the field values are after they are modified.If the action is Add or Delete then 2 and 3 will be the same.I have already implemented this using XMLSerialisation (but not using any of the design patterns) and my XML output looks like this.
<?xml version="1.0" encoding="utf-8"?>
<ActivityItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<UserID>26</UserID>
<FormTitle>frmCustomer</FormTitle>

The solution can handle different areas of the system with different number of fields (i.e the same thing works when you are modifying Products for instance).is there a well defined design pattern to deal with this kind of behavior?

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

I have a form which uses a table adapter to read a table:Me.TblOrdersTableAdapter.Fill(Me.WorkDataSet.tblOrders)I want to change it so it only reads 1 specific record (variable at run time). This is for an Access database. To do that I could add a filter to the Fill query or make another query with a filter but I don't know the code to reference a field on a form. Can anyone supply the correct way to reference a field in a table adapter query, if it is possible, or direct me to a better way?
