Creating A POS (point Of Sales) System
Dec 15, 2011I have just finished college and I am awaiting my exam date. I have created some desktop applications for my portfolio, but now I want to create a Point of Sales (POS) system to add to the list.I notice in supermarkets and various shops that POS systems use touch screen monitors to interact with the program.My first question is, do I need to use different code or controls in my applications so they can be used with touch screen monitors.I have created an application for hotels for booking rooms (not for a client, just as a demo project), but if there is anyone out there who could give me some pointers on how to create the POS system.I will be doing some research and I will start designing some controls over the next few days. I am looking forward to getting this project started.

Jul 22, 2011Declaring this API:

Friend Shared Function WindowFromPoint(ByVal Point As System.Drawning.Point) As IntPtr

If I execute the Code Analysis I obtain this warning (The text is translated from italian, probably in the english language should be a bit different)
Warning 13 CA1901: Microsoft.Portability: According to the code statement, the parameter 'Point' of P / Invoke 'NativeMethods.WindowFromPoint (Point)' will be 8 bytes on 32-bit platforms. This is incorrect since the actual declaration native API indicating that it should be 4 bytes on 32-bit platforms. Consult the documentation MSDN Platform SDK to determine the type of data to be used in place of 'Point'
Now, since the structure System.Drawning.Point consists of two Int32 (4 bit) Integer: [URL]
I don't understand why this warning.
WindowFromPoint is normally used with the position of the cursor, Cursor.Position, which is a System.Drawning.Point.... Dim Hwnd as IntPtr = WindowFromPoint(Cursor.Position)
what whould I have to use instread a Point?

View 4 RepliesEmail Code Works On Local System But Not From Web Server?
May 2, 2011I have developed an ASP.Net 2.0 application and I am facing problem in sending email from my Web Server. Following is the VB code I have used to send email from my web application. Thing is when I try to send email from my local system (laptop) the email goes out fine and reaches the recipient address instantly but when I try to send email from my web server it fails.My hosting provider gave me a relay-host address for sending out email. The email goes out fine but the relay host has an annoying amount of delay in email delivery which is a problem during the sign up process.
Here is the code I am using:I have imported system.net.mail in my code and used async="true" on the aspx page.
Private Sub SendMail(ByVal actcd As String)
Dim mailMessage As New System.Net.Mail.MailMessage
mailMessage.From = New MailAddress(support@ihomejobs.com)

I have tried the above settings and they work fine from outlook and the application when tried on my laptop but these settings fail on web server.I want to send email from my web server without using a relay-host.

View 2 RepliesAuto-generate - Updating Function - Hospital System Which Works With A Access Database ?
Jun 21, 2010I am using vb to make a hospital system which works with a access database. i am having an issue with the updating function to the database, this time round instead of hard codding the connection i used the connection/data source wizard, in microsoft visual studio 2008 and there fore most of the code has been auto generated for me, which includes the insert, delete and update funtions from what i can find and what i have read vb is ment to also auto generate this which it is not. the funny thing is that i can close the program down and reload it (as long as i haven't opened the database) and my changes are still there but if i go and open the database and it hasn't changed. also i can change the database through the use of the Dataset connections in the datasource tab but not int he program the code ive found and believe that is meant to update the database
This is running off a couple of buttons i also have a update query but have know way of accessing it

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.

Calculating Point-to-point Directions On A 2-D Grid?
Mar 11, 2012I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize

View 1 RepliesMove From Point A To Point B Along An Angle?
Mar 14, 2009I need to move an ellipse from a known point on the screen to another known point on the screen.
I've tried using For.....Loops with less than desired results.
I can't remember everything I've tried, a lot of trial and error has been layed to waste. Lol
I've ended up with this code after putting together what I've tried, what I've learned elsewhere, and a couple of posts I've read on here.
All I want to do is move the ellipse from one point to the other along a straight line that forms the angle between the two points (X1,Y1) and (X2,Y2), make it grow from 2 pixels at it's start, to about 80 pixels by the time it reaches half way, then shrink from 80 pixels back down to 2 pixels by the time it reaches the point (X2,Y2).
Easier said than done.
Here's what I have at the present.....
Dim W As Integer
Dim H As Integer
Dim Num As Integer
[Code].....
....This seems like such a simple task, yet it's been a week since I came up with the idea, and I've had little success.
