I have a program that dynamically generates new VB code, and needs to call that code later on. How do I get it to run code from a text file? Is there any command to extract lines from text files and run them as code?

One of the features of my new Vb game is the ability to modularly add and remove in-game items. However, in order to add these items I figure their effects should be recorded in code in the text file they will be stored in.In short, I want to store code in a text file and then have it run on command
Furthermore, is there a way I could put all of the code on one line?
I'm working in VB.Net w/ WPF and I need to create a DataGrid at run-time (in the code-behind) with the text in each grid cell able to wrap. I've found a lot of examples showing how to do this in the XML but I can't find anything explaining how this is done in the code-behind. I'm stuck trying to figure out how the DataGridTemplateColumn, CellTemplate, and DataTemplate all work together.
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
[code]....
I think the problem is with the binding and the textblock property. Something like this would make more sense but it doesn't work...
Dim b1 As New Binding("Wrap")
factory1.SetValue(TextBlock.TextWrapping, b1)

I have a text document that stores around 200 commands ,each on its own line with a value of either 0 or 1 after them. This determins if that command is ON or OFF.
I need to be able to manipulate the on/off values for 5 specific commands using a check box to say "turn this one on" if box is marked. or vice-versa.[code]...
I have no code specifically for this part of my project just saying this ahead of time.I have not used text files that are inside my project but I want to be able to open the file when I load my form and save it when I close my form.I know how to save manualy and same with opening but that defeats the purpose this has to do as much as possible on its own.All I have are code from a project I made a while back which was a notepad program.[code]however I need this to all happen on its own and it needs to install these text files with the program hence why they are in with the project there are about 30 text files that will need to be with it so if I can get help with one then I can figure the rest out.
View 3 RepliesI'm trying to open a text file that was already generated with info inside.I want to read specific lines and have them changed via user input.the lines are not consistently on the same "line".An example of the text I'm trying to read and change is:
// General (upgradeable) values the Player sees for each system
hullLevel = 1700
weaponsLevel = 1450
[code]....
The "H" in hullLevel shows up in line 26 in some of the files, line 27 in other, line 36 in some others and line 37 in yet others.
The reason this jumps around is that this comes from a file that is edited by other modders when they create a ship for a game that I'm modding.My program is designed to allow the user to visually see a representation of how strong and well equiped a ship is and change the values of each line with a slider bar.I have all the slider bar and progress bar code worked out.
I just need a way to reliably pull these lines no matter where they are from the ship file chosen by the user so that the program can edit them without disturbing the rest of the text in the file.
Im wonder how i can create a textfile from the text inside in the textbox. I have already begun with the code, but i get an error.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim output As String = Nothing
output = TextBox2.Text
output = GetFileContents("C: est.txt")
End Sub
How do i make it works?

im new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.

I 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':
Dim RXArray(2047) As Char ' Array to hold received characters
Dim RXCnt As Integer ' Received character count

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.
