Windows Forms Implementing roles in a client application
Hi, I am working on a client windows forms application. I would like to enable/ disable menu items according to roles of already logged in-users, and prevent certain actions from being performed.

Visual FoxPro How to use the tables of a Form
I am having problem using the tables listed in its data environment, I would like to zap the records, append some data and replace some records but when I used the zap command it says that the table should be used in exclusive mode, what should I do Hi, When you use a temporary cursor, it's created on each person's machine, for the life of the program or until it's closed. Since you were Zapping your table each time you use it I assumed you did not need the data beyond the life of your application. You will need to create this cursor in code each time you want to use it. You can do this in the Load() of your form. I'm not sure what ...Show All

.NET Development Erroneously empty DataReader
A method that has successfully returned a Datareader for many queries has started returning a DataReader with no rows. No error is generated as a true DataReader object is present, just empty (I can force an error by submitting an incorrect SQLquery). The same query run in Access works. It makes no difference whether I submit the query as SQL or call a stored procedure in Access with the same SQL. If I reduce the query to a simple SELECT (e.g. SELECT * FROM db_ac_ip) the datareader is filled correctly. Adding WHERE or GROUP BY clauses results (wrongly) in the empty DataReader. Using a Dataset in place of a DataReader also results in ...Show All

Visual Studio Express Editions Public/Private Sub Issue
I am sure this question has alot to do with my inexperience with VB...so its probably something simple. I have a form with some text boxes on it. I have them set to be ReadOnly by default. I want to make it so they can be enabled by opening a dialog box and typing a password. So I created a public sub( ) that basically just enables the form fields when the correct password is typed. The problem is that the statement that makes ReadOnly=False seems to be ignored. In fact, even if I try to just show the value of one the textboxes in a messageBox it comes back blank. On the other hand if I make a private sub ( ) and put it on the same ...Show All

.NET Development What is the best n-tier solution?
In Visual Studio 2005 & ASP.NET 2.0 What is the best n-tier solution A Dataset.xsd through the designer or Hand written class's. Hi, Personally, I would prefer a hand written class. This is for the simple reason that I have full control over it. What I mean is that I could easily try different approach on my code when I create the class. Unlike the .xsd which is being generated by the system. But using code-generated classes could speed up your developement. So if your in a hurry the use the code-generated but if you have lots of time, then create the classes youself... cheers, Paul ...Show All
