How To Make A Point Of Origin In Vb
Dec 13, 2011Public Class GameV2
'Easy axis
'horizontal
Dim x1 As Integer = 200
Dim y1 As Integer = 0
Dim x2 As Integer = 200
[Code]...
I would like to know how to make the point of origin where the two black lines meet, because my game is a coordinates game. I will be converting entered numbers into coordinates on the grid. Another problem is that the point of origin will change, if the person chooses hard difficulty.I can provide more code if necessary

Mar 14, 2012I want to check if two directories are pointing to the same place. Of course string based compare can be done easy but I also want to check for the situation in which a mapping points to the same location. Hence if m:dataapplicApicturesjpg n:applicApicturesjpg point to the same location it must be flagged. I have already searched I know there is something like GetFileInformationByHandle but I don't want to create a file, so I have not got a handle.

View 2 RepliesDetermine The Origin Of A Process Kill Command?
May 5, 2011I'm trying to figure out if there is a way to programmatically determine how a program was exited. For example I'm sure many of you are familiar with the latest malware that detects antiviral software and ends the process and I know we are all familiar with Task Manager's kill process option. The end that I'm seeking is to find out how to utilize WMI, .NET, Win32, or any other Windows feature or programming tool set to determine the source of a process kill command.
Now to be honest I don't want to prevent the kill command from executing, I'm not trying to hinder the user by denying them the ability to end unwanted processes I'm just trying to figure out and document if a users ends a program normally, if TaskMan was used to force kill, or if another program is purposefully interfering.

Admin Backend Approve / Reject Content
Mar 7, 2009I'm creating an admin backend on my site. All the user content that goes on the site will be stored in a database table called Pending. There are other tables where the content will go once approved (Guestbook, Quotes) but if the content is rejected, it'll just be deleted.I know how to delete the content from the database, but I'm having problems will the approval system.On the approval screen, the admin will see a DataGrid that's databound to the Pending table. There's a button that the admin will click to approve the content (based on a checkbox selection or input of a uniqueidentifier entered into a textbox.Can anyone give me an idea on how to move the content from one table to another? Some sample code would be very nice.I'm using VS2005 with SQL Server 2005 Express.

View 3 RepliesCheck If An SQL Connection Is Still Valid?
Jun 4, 2011I have an VB.NET application. This Application is permanently resident in memory and minimized to the tray area because we use it very often. The problem comes in when we VPN into a client's site. These VPN connections trash all other network connections to and from our machines.Then every time my VB.NET application refreshes its database, errors start occurring, because the machine has lost connectivity to the SQL server, however, these are not at the connection level, but only when the reader attempts to read.
I am checking for connection.open, but because of the SQL connection pooling, I just get a previous connection that was valid before the network was cut. Is there anyway to check if an actual SQL connection is valid, prior to re-issuing a connection from the pool?[code]...

View 2 RepliesVS 2010 : Search For Text Within A String (Starting Point And Ending Point)?
Dec 31, 2010I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

View 9 RepliesCheck Internet / Network Connection ?
Nov 19, 2011This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.
If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.
If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...
Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.
I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.
All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.

View 3 RepliesCheck What Application Block Connection?
Dec 3, 2009I'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?
DB/Reporting :: Check If Sql Connection Is Good?
May 31, 2009I have a little problem with checking if a sql connection is good.
Attached here i have a simple vb.net program that should check if the sql connection to the sql server is good. If i just run it once it works very well. But if i use it in a timer and check the connection to the sql server every 10sec it will only tell me that the connection is good (V=0).
I have tested the code with turning of the sql server service.

Dim sqlconnection As New System.Data.SqlClient.SqlConnection(connect)
