I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

I have a tabcontrol with a number of tab pages each of which contains a DataGridView control. I populate each DataGirdView form a local SQL Server. The method which does this works fine. The problem I'm having is I want to use the same method to populate each DataGridView control. I created a private member variable called mDataGridView as a DataGridView and use the TabControl SelectedTab property to determine which tab page the user has selected. I then try the following

I then use mDataGridView in my method which retrieves data from the SQL database. Although the compiler dosn't gag at this it doesn't work. Am I right in thinking that mDataGridView references dgvQuoteTemplate?

Two questions:
1) I have a stored procedure that retrieves item information from a SQL Express database. Should I attempt to do the rounding the stored proc or client side in the app?
2) My rounding needs to be custom. I have a figure that goes down to the 4 place meaing x.0000 if the 3rd digit is 4 or more then I would round up to the nearest cent x.00 if it is 3 and below I would round down. I have looked at the math functions in vb.net and I dont see right out the gate how to accomplish this.
So my question is should rounding be done in SQL or client side and if it is client side do any of you have pointers on how to slice and dice this?

why the following Sub does not work as expected. It has no compile errors but it does not work. It suppose to validate a password entered by a user on a login form with users password in a table called 'passwd' in the LgaPayroll database. If the password entered matches what is in the password field of the 'passwd' table then it will display a form else, it will tell the user 'The password you enter was invalid". My problem is; even when you entered a password that is in the 'passwd' table, it is tells you 'The password you enter was invalid'. Below is the Sub:
Private Sub btnOK_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOK.Click
' Set the SelectCommand properties...

what I have mainform with two labels Text is User and Pass. I have a button on the main form called Set that opens the login form. There I have two textboxes, UserName and PassWord. and two buttons Save and Load. When you type the user names & password into the textboxes, and click save, if file exists you will be prompted to replace existing file. I also have added code to display the user name and password in the labels on the main form. Once you save the file I can now close the project and reopen the project click the set button to bring up the login form, and click load. Now the file is read and the saved username and password text is displayed in the proper textboxes on the login form.I also added the code to display the textboxes in the labels on the main form. Now I'm trying to use the lable text to fill the username and password textboxes on a login form of a website. I've tinkered with several different codes to do this but everything I have done has failed. I really need help getting started in the right direction.
