I can't figure out the syntax for searching an array of stored words for a string matching an input string. I understand the pseudocode of it, but I'm tripping up over what variables I need to put where, and how they should be formatted. More than happy to provide more details should anyone request them.

I have to scan through documents. Excell, Word, txt, ect looking for company names that match a pre-difined list of companies.I then email the companies some specifics in regards to that doc.The problem I have been having recently is that the list of companies keeps growing and I am starting to miss some more than I used to.What I would like to build is a tiny app that has 2 Text boxes.1 on the left for input (where I would copy/paste) the document text I receive.and one on the right for the output where it will highlight any line that contains the name of any of the pre-defined companies.
I started toying with the idea and so far I have form with a SplitContainer. Within that SplitContainer each side has a TextBox... Below the Textbox on the left hand side splitcontainer I have a submit button with no actions currently assigned to it.
I am very basic with this right now and I'm certain there are ways to do this even more simply than the 2D array, however that is what we are working on right now.

View 1 RepliesI am trying to search for a particular string on a *.txt file, while i can do this i want to be able to do it without having to type the exact string.
For example:
if i search "string" i find "string" but not "String" the big letter wrecks the search... anyone knows how to do a search like this?
And i want also to give me an incremental search while i am typing on a list box.
For example:
if i type "s" it appears, sangoku,slb, siemens,sentence,...., string,...
on the listbox. These are words that exist on the *.txt file i am reading.
if i type "st" it appears only string and any other word that starts with "st"
it would be an automatic search without having to press enter, or any search button. Just by pressing the keyboard on the letter we wanted the search would be made.
Iam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.
The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.

View 2 RepliesI want to do in vb.net what I would have done in SQL with the CHARINDEX command. That is, I want to interrogate a string and ask, 'Does this string contain a hyphen? If so, whereabouts in the string is it?' I tried Googling this but as with a lot of things in vb.net, there's always a million different answers given with each response seemingly trying to overcomplicate the issue and out-code the previous one. Hence my confusion.

View 1 RepliesIn this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.

I have finally been stumped this semester in my Visual basic course. Mainly because I have to write a program that is started from something that I have not created. I have to create a program that will take in info from the user, then spit out the poker hand that they are holding. For instance, the user will type in 1 for ace, 2 for 2, 3 for 3......10 for 10, 11 for Jack, and then in the next column type in C for Clubs, S for Spades.. and so on. Here is the code I have been given:

How can I make a control array? Or the equivalent.
I am used to Visual Basic 6 which presents the option of whether to create a control array when I copy and paste and control.
the following code shows invalid qualifier when executed
Dim strs As String
Dim insStr As String
Dim strRes As String
strs = "This is VB.NET Test"
insStr = "Insert"
strRes = strs.Insert(insStr)
I know that this was an advanced compiler option in previous versions of Visual Studio, is there a way to disable array bounds checking in Visual Studio 2008? There's no option for it that I can see.

View 2 RepliesI've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I have been tasked to create a Visual Basic console script that asks the user 5 times in a row to input a number into an array (sales figures in thousands), Then you display these results as a sort of tally chart.

The output would be
