I would like to be able to run code from a text file - is that possible.Ideally multiple applications will read this file and all behave according to the code inside the file.rather than having to keep rebuilding and distributing new versions./

View 3 RepliesI am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

View 9 RepliesWith the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb':

I noticed that my application is running a bit slow. This is a Windows Service built using VB2010 with SQL Server as a back end. Its main function is to poll a folder looking for a text file. If found it reads the text file and imports the data into SQL Server.
While the slowness could be caused by a number of reasons, I am looking at my code to determine if it could be more efficient. Below I've pasted snippets of code where I initialize the DB connection and execute SQL statements. I've also included a snippet that illustrates how I am processing the text file.
I'd appreciate if the group could have a look at these and let me know if the method that I am using is the most efficient possible. At this time I am also focusing on other probable issues, but I can't rule out the possibility that the code that is in place might be a contributing factor.

I've got 2 seperated programs.
One is a program where you can select a product and select how many of them you want. Then the total price wil be displayedin a label. And the list of selected products will be saved in a .txt file.
The second program is an Edit program. The user can edit his selected products. Here he can change the total of a product.So if he had selected 1, he can change it to three or something. When the user clicks the button Save. The changes will besaved in the same .txt file and the total price will also be changed and displayed in program one.
Program one is compleet.Program two has problems and here i need your help:- the user can't make a change in the numbers, seems that the textbox is read-only or something. How to solve?- Then when i click save, the changed must be saved in the .txt ( i can't test this yet because no changes can't be made)- the total new price must be showed in program 1 (i think i programmed this well, but can you take a look)
