I'm developing a "small" warehouse-management WebApplication for few users(5-10 parralel) but with a complex authorization system(checking if pages,menus,TabPanels, UserControls and even single controls are visible or enabled) and permanent and frequent access. Because i've only limited experiences with the ASP.Net MembershipProvider, i'm unsure what's the best approach for following goal:
I want to hold all users, roles and frequently used masterdata in the Cache(in a Dataset). Hence every readonly access should be faster and causes less traffic than always using the database. On updates,deletes and inserts i would update the cached dataset and also the database.
Can i use or extend the SqlMembershipProvider to achieve this goal and if possible how?
I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.
View 1 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --

I have a program that uses Lucene.net in ASP.NET (VB.NET), when you search a term, results are stored in the Lucene.net data structure "hits".I want to read out the hits into an data structure and work with them, after that I display them in a DataGrid.By searching a term with a lot of results, often (but not always) there is an error by following code :
For i = 0 To results - 1 Step 1

[URL]notice that the tag topic count for C# is in excess of 8900 while the vb.net tag topic count is sitting at 1019. Does this mean that there is a shift towards c# as a .net language of choice. the only reason I decided to build some applications for work using c# was that I like curly braces - after all vb has the same language support as c#, doesn't it so there should be no advantage to choosing one over the other; other than curly braces;)

I have an StackOverflowException in one of my DB functions that I don't know how to deal with. I have a SQLite database with one table "tblEmployees" that holds records for each employees (several thousand posts) and usually this function runs without any problem.
But sometimes after the the function is called a thousand times it breaks with an StackOverflowException at the line "ReturnTable.Load(reader)" with the message: An unhandled exception of type 'System.StackOverflowException' occurred in System.Data.SQLite.dll
If I restart the application it has no problem to continue with the exact same post it last crashed on. I can also make the exactly same DB-call from SQLite Admin at the crash time without no problems.
Here is the code:
[Code]...
When crashes, the reader has "Property evaluation failed." in all values.I assume there is some problem with allocated memory that isn't released correctly, but can't figure out what object it's all about. The DB-connection opens when the DB-class object is created and closes on main form Dispose.
Should I maybe dispose the mycommand object every time in a finally block? But wouldn't that result in a closed DB-connection?
I need some advice to make a small application running, i need to calculate a integer prime and i use a recursive function inside a while true loop, first i get a random number with random class and then i call the recursive function that checks if it's prime, if it's prime it exits the while. Sometimes it works others throws the stack overflow exception, what i must do to get rid off this exception?

I understand that this is bad programming practice and redundant coding but I am curios.
I am simply counting a number up to 9999999 in a while loop. The Add() function simply increases that number and prints it out.
Inside the Add() Function I call the Add() function.
My program successfully prints out 12000ish numbers before I get a StackOverflow Exception.
So my question = Is there any way to ignore this error and keep counting?
I have tried On Error Resume, Try/Catch, and throw
My code is as follows.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
While number1 < 9999999

I have 2 classess. Role and User like this
Role
Public Class Role
Public Property RoleID As Integer
Public Property CreatedBy As User
[code]....
The situation is like when we create roles, we will save who created this role. So i have a CreatedBy Property of type User. Similarly when we create a User, we will mention what role the new user belongs to .So i have a property called "Role" of type "Role". This circular reference giving me StackOverflow exception as its recursive when i create an object of User class.How do i handle this ? should i restucture my entties ? how ?
I have done some reading and it seems that this error comes from recursive calls but I have not done anything in my form_closing handler except for call me.close, that's it.
So I don't understand how this exception has entered my project. All of my data and functionality is still working as I expect. It just seems to throw this exception when I try and exit my project.
what I could check to prevent something like this from happening?

I am wanting to get the users IP address (the logged in user will be running the application under there user context on there local PC), but many PC's in our environment have multiple NIC's that have been added by VMWare Workstation, I would like to exclude these type of bridged connections and only show the "primary" NIC on the PC.The following function will get the IPv4 address, however on my test PC it is returning the bridged connection and not the IP Address of the network facing NIC.

'Dim ipEntry As IPHostEntry = Dns.GetHostEntry(computerName)
'Dim tmpAddr As IPAddress() = ipEntry.AddressList

My users have a mixture of DHCP and static addresses so cannot limit the NIC to either of these connection types. We tend to have a 172.16.x.x IP range, so is there a way to modify the above function so that it will only return a 172.16.x.x address?
