Keeping Count And Storing Of Text Instances?
Sep 22, 2011
I would like to make a simple code that counts the top three most recurring lines/ text in a txt file then saves that line/ text to another text file (this in turn will be read into AutoCAD's variable system).Forgetting the AutoCAD part which I can manage how do I in VB.net save the 3 most recurring lines of text each to its own text file see example below:
Text file to be read reads as follows:
APG
BTR
VTS
[code]....
The VB.net program would then save the text VTS to mostused.txt BTR to 2ndmostused.txt and APG to 3rdmostused.txt?

When I create more than one instance of the same form and I call a method on any of these instances, the code only fires on the most recently created instance. Even when I click a button on that form, it executes on the other form. How can I call these and keep them as distinct objects?
For example: if I build Form1 with a public method called ChangeMyColor and a button to call that method. Then in the main app I set MyForm1 = New Form1
and MyForm2 = New Form1, then call MyForm1.ChangeMyColor, the color changes on the second instance. Even if I click that button on the first instance, the color still changes on the second.

I have a VB2010 application that must run as multiple instances on the same PC (it is a controlling/monitoring program of several devices, each instance of the program control one device)
Of course, the same application must save its own setting in different place, one for each device. For example, if I start the application for the device 3, I have to save the setting in a place marked as "3", in this way, when I start the application for device 4 it will load the settings for device 4 and not 3.
Of course all labels and similar stuffs must refer the starting device: i.e. the mdi caption must report "device 4", and so on...
In vb6 I created a shortcut with a command line and made my application accepting command line parameters.
In this way I could start the application passing the device number too. For example "myapp.exe 3" start my application for the device 3.
I stored all settings in several INI file, each one for a device: setting1.ini, setting2.ini, setting3.ini, ....
I was wondering if in vb2010 would be a better way to do that.
1. How could I start multiple instances?
2. How could I store the settings?

I have an exe that runs from the server. The instances are shown on the server. So the questionis how can I get the following code to count the instances on the server.
HTML
Dim oProcess As Process
Dim nCount As Integer = 0
For Each oProcess In System.Diagnostics.Process.GetProcessesByName("MSTP")
nCount = nCount + 1
Next
(MSTP is the name of the application's exe.)

I have so many form to manage. I want to count the instances of a particular form. For example, if I show my form1 two times then there must be a counter for my form1 and if I also shown my form2 another counter for form2.I want to do this to minimize the instances of forms to be shown so that my resources will not burden to much.I want my code to be generic so that I can easily call it for my other forms.

My application outputs log text every so often and I need the user to be able to see the latest text at all times. I've tried a label, a text box and a rich text box, but I can't figure out a way to show the bottom-most text at all times.

What happens here is when I click on anyone of the radio buttons the text box score sets the value to either 0,1,2,3,4 but when I go the next case it goes back to 0 instead of keeping the value. I tried many different techniques while going about this none seem to work.

This gets the document and adds text into it, exactly what i want it to do. But it replaces the whole document. I just want it to add text at the start of the document. Not replace the whole document.

MSDN only discusses strings, images, audio, etc.. but does not cover text files.
I have a text file with about 6k lines of short strings, each on its own line, added to my project's resources and I'm trying to .add each line to a collection. I've tried about 7 or 8 things, not all using StreamReader, but I can't find documentation on this anywhere.
Here is the last thing I tried:
Dim JunkStrings As New Collection
Dim sr As StreamReader = New StreamReader(My.Resources.shorts)
Do While sr.Peek() >= 0
[Code].....
I just can't find the equivalent to this that reads lines from a text file out of my.resources.

I'm trying to read data from a text file with multiple records and fields separated by tabs to store into arrays, which I later want to output into a textbox on the form. The problem is that with the code I've written, when I debug it it exits the sub procedure when it enters the first loop where the parser is reading the text file. There are no error messages, it just exits? I'm not even sure if what I've written is possible. Here's what I've written so far:

Here is what I would like to do:
- Store string data from a 'sign in' form into a text file. This text file must be one that is saved even after the user exits the program. The text file must also be one that will stay with the program even after it is published (executable).
- Be able to write to/read from the file for purposes of displaying some or all of that data on a form.
I use an Application Setting to do this - of type 'Specialized String Collection'. I tried this, but for some reason I could not get it to work. It was a good idea, but I need to be able to SEE the data that has been saved, and with a setting it seems like that is not easily done. I've decided that I either need to use a simple text file or a 1-table database for this. I would prefer just a text file, but in either case, it needs to be part of the .exe when published.
I have added a text file to my project, but I am not sure if it will be "included" in the project when I publish it. The path of the file I've added is in 'My Documents', but in my code, I will have to specify the path in order to use Streamwriter. How will this affect the program when I publish it? I felt the need to make a new thread because on my last one we had been mainly talking about settings, and I've decided that isn't the best option for me.
