Hello I want some help with a code to search through the text file and to separate the text from a separator value followed by a rogue(stopping) value.
Each line of text in the text file is: for example with sample data:
DAC11010|This is a Desk and a chair|$100;.
In the above example has the | sign as a seperator value and ;sign as a rogue(stopping) value. The separator value separate the text DAC11010 , This is a Desk and a chair , $100 the rogue(stopping) value means that it it is the EOLN(end of line) and ready to check the next line.
The separated text goes to 3 ListBoxes and the data added one after the other. The DAC11010 goes to the lstItemCode , This is a desk and chair goes to the lstDescription , $100 goes to the lstPrice.
I would like if someone would volunteer to help me program the code in vb.net. I hope I made myself clear.
Thank you [shannon].
If you haven't already done so, please turn on Option Strict. This is a 2 part process. First for the current project - In Solution Explorer double click My Project. Choose Compile on the left. In the Option Strict drop-down select ON. Second for future projects - Go to the Tools Menu -> Options -> Projects and Solutions -> VB Defaults. In the Option Strict drop-down select ON. This will save you from bugs at runtime.
I will not write the code for you. That is not the purpose of Stack Overflow. We help with specific problems you are having with your code. You don't appear to have any code.
I will explain one way your goal might be accomplished.
Declare 3 New List(Of String) variables to hold the data for the three list boxes. We will be looping through the text files lines but we don't want to update the user interface until after the loop so we will collect the data in memory.
You will need to import System.IO to use methods of the File class. You can use File.ReadAllLines to get an array of strings; each member of the array will contain one line from the text file.
Next, you will want to loop through the lines splitting each line into 3 sections. Use the For Each...Next type of loop. You can use the String.Split method passing in your "|"c parameter. The c tells the compiler that this is a Char not a string because .Split is expecting a Char Now you can use the .Add method to add the sections to the appropriate list.
After the loop, you can assign the 3 list to the .DataSource property of the appropriate ListBox.
Now write the code and if you have any problems ask a new question showing the specific code where you are having the problem.

I've been working on an independent project for a client of mine. They wanted to produce a button that, upon the user-click, it would open up a user-form and have a variety of macro-related options to choose from: a drop-down list, checkbox, option select button, etc.
I created a test formula and submitted it to the client; they enjoyed it thoroughly and decided to sent me a file to 'copy & paste' my original code within their excel file.
Problem is; because I'm a tad bit inexperienced with VBA I've run into a problem where once I click the button - the user form doesn't show up.
Below is a Dropbox link of the original file I created and it's original code; as well as the file that I am trying to copy.
Any help would be all welcome and appreciated.

OriginalProject.xlsm has a form named honor_roll_form which contains 100 lines of code.
CopyOfOriginal.xlsm has a form named UserForm1 which contains no useful code.
I do not believe there is any method of directly copying user forms from one workbook to another. Instead
Within VB Editor of OriginalProject.xlsm, select honor_roll_form.
Click File then Export File and save the form on your desktop or where ever you like.
You will now have two files on your desktop; one with an extension of frm and one with an extension of frx.
Within VB Editor of CopyOfOriginal.xlsm, click File then Import file.
Import honor_roll_form.frm
When I try clicking button "Honor Roll", I get "Method or data member not found" for project1Box. I will investigate after dinner (18:57 here) unless you tell me you already know why I am getting this error.
Extra comments in response to request from OP
It is late here but I have started looking down sub execute_button_Click within the second CopyOfOriginal.xlsm. I will comment on what I see even if it is not directly relevant to the non-execution of the macro.
If you open the VB Editor and look on the left you will see the Project Explorer. Near the top you will see:
Microsoft Excel Objects
Sheet1 (Sheet1)
I have always found this confusing. The first “Sheet1” is Excel’s Id for the worksheet and cannot be changed. The second “Sheet1” is the default name for the worksheet which can be changed. You can write Sheet1.Range("A1") or Worksheets("Sheet1").Range("A1"). That is: you can reference a worksheet by its Id or its name. You have named a variable of type Worksheet as Sheet1. Using Excel’s names as variable names can lead to bizarre errors so it is important to avoid doing anything like this.
It is better to always use meaningful names. At the moment, you know what Sheet1 means but if you come back to this macro in six or twelve months will you remember. I would use a variable as you have but I would name it WshtCis208 or WshtVBAProg or something similar.
Set ID = Range(Sheet1.Cells(2, 1), Sheet1.Cells(52, 1)) could be written as:
With WshtCis208
Set ID = Range(.Cells(2, 1), .Cells(52, 1))
End With
Using With statements produces faster code and, almost always, code that it easier to read.
“52” is the current bottom row for this table. Will you amend the macro for them every time they add or remove a student? There are several techniques for finding the last row, none of which is perfect in every situation. The technique that is the most convenient most of the time is:
Const ColCis208Id as Long = 1
Const ColCis208MidTermExam as Long = 5
Dim RowCis208Last as Long
RowCis208Last = .Cells(.Rows.Count, ColCis208Id).End(xlUp).Row
At the moment, column 1 is the Id column. It is perhaps unlikely that the Id column will move but it is very likely that some of the others columns will move when some new column is identified as useful. Do you want to scan the code trying to decide which 5s refer to the MidtermExam column when a Project3 column is added?
Constants allow you to name literals that might change. It makes your code easier to read and saves so much pain when a value changes.
.Rows.Count gives the number of rows in a worksheet for the current version of Excel so .Cells(.Rows.Count, ColCis208Id) identifies the bottom cell of column 1. End(xlUp).Row says go up until you hit a cell with a value and returns its row number. It is the VBA equivalent of Ctrl+Up.
The next statement subjectCount = … fails because projectBox does not exist on the form. You have changed the captions but not the names.
As far as I can see the form fails to execute because you have started updating it but have not finished.
Ok.
So I am working on a project, irrelevant, and I have a bunch (8) of ComboBoxes (they are in DropDownList mode) and there is 8 save files. I have them being imported and converted to strings:
Using class2 As New StreamReader(path & "SaveData/classdata/classdata2.NIC")
Dim fdcount1 As String
fdcount = class2.ReadToEnd()
MessageBox.Show(fdcount1)
hr2choice.SelectedItem = fdcount1
End Using
I already tested this, and it seems to be working.
(Test code I used:)
MessageBox.Show(fdcount1)
and it showed the value ("DiVita")
Despite this, when I tried setting the ComboBox value to this, it did not seem to work.
The ComboBox does have this value in it, and if I try this, it works:
hr2choice.SelectedItem = "DiVita"
For whatever reasons though, it does not work when I try doing it directly from the string.
Thanks for any help with this!

To answer this, I have to assume that the data in the text file is formatted as one line for each piece of data.
There seems to be a couple of issues with your code. fdcount is just declared as a string where it should be an array to make it easier to access each line that is read from the file. fdcount1 has no relationship to fdcount - it is a completely separate entity, so the data in fdcount1 is coming from somewhere else.
Rather than the above code, It's easier to use this
Dim fdcount() As String
fdcount = File.ReadAllLines("SaveData/classdata/classdata2.NIC")
MessageBox.Show(fdcount(1))
Note that fdcount is declared as an Array of String. The 2nd line does all the opening, reading into the array, and closing of the file.
You can then access each element of the array as shown in the 3rd line.
I am fairly new to VBA (Word 2010) and I'm unsure if something I'd like to do is even possible in the way that I want to do it, or if I need to investigate completely different avenues. I want to be able to print ranges (or items) that are not currently enumerated as part of either wdPrintOutRange or wdPrintOutItem. Is it possible to define a member of a wd enumeration?
As an example, I'd like to be able to print comments by a particular user. wdPrintComments is a member of the wdPrintOutItem enumeration, but, I only want comments that have an Initial value of JQC. Can I define a wdPrintCommentsJQC constant? My code is reasonably simple; I have a userform that lets the user pick some settings (comments by user, endnotes only, etc.) and a Run button whose Click event should generate a PrintOut method with the proper attributes. Am I on the wrong track?
(If it matters, the Initial values will be known to me as I write the code. I have a discrete list.)
No, it's not possible to add a constant to a predefined enumeration type.
However, one possible way to do this would be to build a string of page numbers which contain the items you wish to print, open the print dialog in the "dialogs" collection, and set it to print a specified range, andinsert the string containing the list of pages (separate them with commas). Finally, execute the .show method of the print dialog to show it to the user and give them the opportunity to set any other items and click the "ok" button. I've done something very similar when I needed to print a specific chapter of a long document, and so I had to specify the "from" section and page and the "to" section and page for the user. Below I just show how to specify a list of pages instead of the ".form" and "to" I was using:
With Dialogs(wdDialogFilePrint)
.Range = wdPrintRangeOfPages
.Pages = "3,5,7-11"
.show
end with
I'm not sure how you want to print the comments (or other elements), but you could create another document and insert what you want to print on this document.
According to what you want, you could insert them as they were (comments, footnotes, etc) or as plain text, or any other format.
I'd like to be able to create a page element which I can feed text and it will form itself into the preferred layout. For instance:
{MACRO DocumentIntro("Introduction to Business Studies", "FP015", "Teachers' Guide")}
with that as a field, the output should be a line, the first two strings a certain size and font, centred, another line and then the third string fonted, sized and centred.
I know that's sort of TeX-like and perhaps beyond the scope of VBA, but if anyone's got any idea how it might be possible, please tell!
EDIT:
Ok, if I put the required information into Keyword, as part of the document properties, with some kind of unique separator, then that gets that info in, and the info will be unique to each document. Next one puts a bookmark where the stuff is going to be displayed. Then one creates an AutoOpen macro that goes to that bookmark, pulls the relevants out of the keywords, and forms the text appropriately into the bookmark's .Selection.
Is that feasible?
You're certainly on the right track here for a coding solution. However, there is a simpler way with no code - this is the type of scenario that Content Controls in Word 2007 were built for and with Fields/Properties, you can bind to content controls (CC). These CC can hold styles (like centered, bold, etc.). No VBA required.
The very easiest thing to do is to pick 3 built-in document properties that you will always want these to be. For example, "Title" could be your first string, "Subject" your second string and "Keywords" your third. Then, just go to the Insert ribbon, Quick Parts, Document Properties and insert, place and format those how you like. Then go to Word's start button (the orb thingy) and then under Prepare choose Properties. Here you can type, for example "Introduction to Business Studies", into the Title box and then just deselect it somehow (like click in another box). The Content Control for Title will be filled in automatically with your text.
If you want to use this for multiple files, just create this file as a .dotx (after CC insertion/placement/formatting and before updating the Document Properties' text). Then every time all you'll have to do is set these three properties with each new file.
Well, yes, it did turn out to be feasible.
Sub autoopen()
Dim sKeywords As String
sKeywords = ActiveDocument.BuiltInDocumentProperties(4)
ActiveDocument.Bookmarks("foo").Select
Selection.Text = sKeywords
End Sub
Okay, I have some filling out to do, but at least the guts of it are there.
I know that often using a for loop to generate repetitive content is the better way than pasting something 20 times and changing each paste to the correct number by hand. But let's say for cases where content is hard-coded and I just want a list from 1-20.
I would like a text editor with a "smart" paste command that takes any number imbedded in a string on the clipboard and increments it each time I paste. If it doesn't exist, I will make a plugin.
I'm trying to think of a good 2-stroke keyboard shortcut to do it, close to the ctrl-V. Maybe ctrl-g or numpad_+ (in an app with no zooming).
Does it exist?
In Zeus this can be easily done as follows:
Column mark the area to be converted to a numbers
Use the Macros, Execute Script menu
Type in numbers to run the numbers Lua macro
Type in the first number of the sequence
The marked area will be replaced by an incrementing sequence of number starting at the first number provided in step 4.
I'm trying to think of a good 2-stroke
keyboard shortcut to do it,
Making this into a key stoke action is as simple as binding the numbers Lua macro to the keyboard.
Here is an example of how it works. If 1 values in the text below are column marked and the macro executed with a starting number of 1000:
Field_1
Field_1
Field_1
Field_1
the following text changes will be made:
Field_1000
Field_1001
Field_1002
Field_1003
Armed bear J has a renumber region command, as well as a case-preserving replace-in-files, which means I often keep it around for those features.
TextPad is another text editor with a Fill Region function, for filling with a character, a string, or incrementing numbers (starting from X, with left- or right-alignment, and space- or zero-filled.)
I used Notepad++ now, but I have to keep TextPad around just for that number-filling function.
