I have a question that relates to identifying words or characters in text boxes.Okay, I know that I can identify the entire text with textbox1.text = "~~~~". But say I want to search for a specific part.e.i.(in textbox)Hello, how are you?(in textbox)How, in code, would I find and select, let's say, the word "how"?Please, if you can help, I need it. I want to learn as much as I can about Visual Basic so I can become a better programmer.
View 13 RepliesHere's my problem i am trying to extract data from a forum

So here's a example
[quote=randombla13] I am the king of the world bla bla

[quote]This line should not be removed[quote]
[quote]
Now as you can see these are the codes you may have seen in many forums
Now want i want .Net to do is filter the the content in a textbox
And remove only the lines marked with red "[quote=randombla13]" from the first line
And the Extra "[quote]" from the end line
As you can see in the example the content has two "Quotes" so i jest want to remove only one from the first line and last line of the content
And note "[quote=randombla13]" the length after the = is Unknown it maybe of 6 characters or less or more

View 2 RepliesI have a text file stored as a string variable. The text file is processed so that it only contains lowercase words and spaces. Now, say I have a static dictionary, which is just a list of specific words, and I want to count, from within the text file, the frequency of each word in the dictionary. For example:
Text file:
i love love vb development although i m a total newbie
Dictionary:
love, development, fire, stone
The output I'd like to see is something like the following, listing both the dictionary word and its count. If it makes coding simpler, it can also only list the dictionary word that appeared in the text.
WORD, COUNT
love, 2
development, 1
fire, 0
stone, 0
Using a regex (eg "w+") I can get all the word matches, but I have no clue how to get the counts that are also in the dictionary, so I'm stuck. Efficiency is crucial here since the dictionary is quite large (~100,000 words) and the text files are not small either (~200kb each).
I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.

View 1 RepliesLet's say I have a textfile which contains paragraphs. Some of the paragraphs start with * or a > character. How do I index the words that start with these characters?
Example:
[code...]
In VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"
i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")

I'd like my application to be able to detect a where a particular USB device has been mounted, and adapt accordingly. Ideally, I'd associate paths with a USB serial number, rather than with a given path. However, I cannot figure out a simple way to access these unique IDs from VB.Net code.
View 1 RepliesMy VB.NET (3.5) application generates Excel reports. Newer versions of Excel support the Office Open XML file format, while older versions don't.

How can I identify the Excel version installed on the local machine?

View 2 RepliesI have a table of data exported to an Excel file that contains a Date/Time Field. The entries in the table are formatted like 01/01/2009 14:00 (military time). Every line in the table contains unique information that is specific to that particular date/time information, 1800 lines of data (the reason that I dont want to hand sort this table). How can I identify the items in the table that fall after a particular time of day? More specifically, I need to identify which of the data fields have a time after 14:00 on that particular day.

My issue is regarding overloaded functions of the already provided IIf function that would handle specific types. As you all know the IIf function provided returns objects, rather a specific type so for my needs I created a few overloaded function to do just that but with a specific type in mind. So having said I have IIf functions for types of booleans, strings, bytes, integers, etc etc.
Now my problem is when I'm trying to pass a byte value to this function that would return one of the two byte values. When I do this the designer keeps confusing my values as an integer value and calls for me to convert it to a byte. If I did this then it would defeat my entire purpose for creating these functions-which is to avoid any conversions. The only way I can solve this is by converting the whole statement itself or the true/false parameter parts individual to specify to the designer that these values are bytes. I'm just hoping there's a way of identifying the difference between bytes and integers..
other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

The problem at hand is to search an Access database for "duplicate" street addresses, given user input of street address, city, state, and zip code.Given the zip code, city and state do not need to be looked at.
My thought was to select off records in the database with the zip code that matches the input, then loop through those records, performing a "similarity" test on the street address field as compared to the input street address. Obviously we cannot test for exact matches (i.e. "SW" vs. "South West", etc.). This problem has obviously been solved before with post office software, algorithms used by mapping applications, etc.
But do you have any thoughts on what algorithm I might implement in a VB 2005 app?

View 2 RepliesI wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
