Have two CSV files containing client records and need to compare the two and then output to a third file those rows where there are differences to the values within the record (row) as well as output those records (rows) on the second file that are not on first file . Example: File 1: KeyField,Name,City, Zip,Location 123,Fred,Chicago,60558,A2 234,Mary,Orlando,12376,4L6 345,George,Pittsburgh,40567, 22 456,Peter,Topeka,00341,234 567,Doc,Birmingham,76543,H86 File 2: KeyField,Name,City,Zip,Location 123,Fred,Chicago,60558,A2 234,Mary,Orlando,12376,4L6 345,George,Boston, 40567,22 456,Peter,Topeka,00341,234 567,Doc,Birmingham,7654,H86 678,Isabel,Guadalajara,87654,M111 The results should create a file containing : 345,George,Boston,40567,22 678,Isabel,Guadalajara,87654,M111 The following code gets me in the neighborhood as a visual check: import os import difflib f=open('original.csv','r') #open …

Hi. I'm trying to create a Traffic simulator and I'm stuck on how to get a Car object to turn into a road.

Reusable Code Snippet vb.Net Progress Bar With Text

A long standing complaint with the standard progress bar control is that there is no easy way to display text. In spite of numerous requests, Microsoft has not included this capability. The following code includes a class, `CustomProgress` which inherits the standard `ProgressBar` and adds such a feature. It is fairly easy to use. If you want to show a percentage progress you set `Text` to a null string and the percentage will be calculated from the `Minimum` and `Maximum` value properties. If you want a custom string then assign it to `Text`. Either the percentge or custom text will …

Hi everyone! I'm making an application which requires users with different permissions/previleges to login and use the application.For example, if the user is "admin", all menu items in the menu bar are shown and enabled. If the user is say "user_group1", some of the menu items are to be hidden. The same for "user_group2", "user_group3", "user_group4" and so on. I could put a code for each specific user in each form but that's a great deal since users and their user groups may be added after application deployment. So it has to be something flexible. I want the user "Administrator" …

Demonstrates using .NET Remoting to broadcast to client subscribers. There are three parts: 1) Server.cs - for console app responsible for broadcasting messages (date/time stamp currently) 2) Client.cs - for console app that registers with server to subscribe to broadcasts 3) Agent.cs - class library that facilitates/eposes the interfaces for our client/server communication To use, create the three project types defined above and include the appropriate code found in this snippet. In both the Server and Client projects, add references to the Agent.DLL project. Then, modify the IP address in the ClientClass's creation of the AbstractServer remoteObject to a string …

An example showing how to use the wx.media.MediaCtrl() widget to play MIDI, MP3, WAV, AU, AVI and MPG audio and video files. I have only tested it with Windows. If you are very ambitious, you could use a random graphics display with the sound, or tie the slider position to a slide presentation.

Hi! I've found this code in the net that merges rows successfully. However, the data is being written in the last row of the merge rows. What I want is that it should be written on the first instead. This is the code: Using gridBrush As Brush = New SolidBrush(Me.dgSM.GridColor), backColorBrush As Brush = New SolidBrush(e.CellStyle.BackColor) Using gridLinePen As Pen = New Pen(gridBrush) e.Graphics.FillRectangle(backColorBrush, e.CellBounds) If intRow < dgSM.Rows.Count - 1 AndAlso dgSM.Rows(intRow + 1).Cells(7).Value.ToString() = e.Value.ToString() Then e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom - 1, e.CellBounds.Right - 1, e.CellBounds.Bottom - 1) e.Graphics.FillRectangle(backColorBrush, e.CellBounds) End If e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1, e.CellBounds.Top, e.CellBounds.Right - …
