I want to mention that I am making this app in VB.NET
I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">
<providers>
<add name="MyProvider"

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
is there a way to generate a random number and then display that number?
like for example i want to say "i got # - # pencils" or something like that

View 4 RepliesI've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.

I once posted a question on generating a policy number by table ID and user selctions from comboboxes. [URL]FYI . I am doing my project in vb, that why i posted it here. I managed to do that when i choose a region and product from two different comboboxes i generate a number but now my problem is that whenever i click on the comboboxes a policy number is generated before i save the record, so if my previous nummber was 72100002 whenever i click on the product combobox i generate a number e.g if i click on it five times by the time i save the number would be 72100007. I am using a stored procedure for this. Is there another way of doing this or i might end up with my first record as 72100001 and my second record 72100006.

View 5 RepliesI have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.
Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.
