I've been programming a game recently and didn't want to make 99 weapons manually. I've tried making a loop do this for me. I've got the loop working, everything is perfect. But when I run the program and list all the Weapon(x).Name [x being any value between 0 & 99] they are all identical... HOWEVER. If I single step through the code it lists all the names from 0 to 99 perfectly fine. Why is it that single stepping through it produces what I want?
Private Sub CreateWeaponList()
Dim StatName(4) As String 'Creating 4 pre-made names for weapons

I have couple of questions with datagridview 1.How to handle the Enter-Key when the user edited the columns value.?I mean, without changing the columns values we can suppress the enter-key by following. No problem. It's working Fine.

View 2 RepliesI have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date. User can poplutes these textboxes for multiple records and hit submit button. On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table. If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label. I got all this to work, but if it throws error message all the data in the grid is wiped out.
How can i keep data in each textbox and still display the error message?
In my program theres a form where the user enters the ID number and other details of a customer. i want the program to be able , If the ID number already exists when the user enters it and clicks on ok, to display an error message telling them that the ID already exists otherwise it adds the id and the details to a database. Im not sure how i would do that im thinking it would be an SQL statement? not sure.

View 6 RepliesI'm using Visual Studio Development Server (Visual Basic 2010) and it works fine. Now I've enabled NTLM Authorization because I want to test the website using a different user account. Now when I try to access the website I always get the following error page:
Server Error in '/' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 10.0.0.0 .I'm using a test account which is a normal user within our domain. I've already set the access rights in my project folder to Full Access for this user but it does not help.
When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
[code]....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
