This switching from VB6 to VB.NET is starting to become a major pain I have a program I am making that loads a list of Vehicles from a text file to ListBox1. When the Selected Item in ListBox1 is clicked, it brings up the Image of that Vehicle, called from an external Image folder, so new Images can be added. I have an 'Add Entry', 'Delete Entry', 'Refresh List', 'Save Changed List', and 'Exit' buttons, all coded and working as I want them to - Everything is working better than I planned, without having to Google my a$$ off finding 'snippets' - I figured most of it out myself - What I am trying to do now is have a ListBox2 populated with a section of the text file:

View 1 RepliesI need some assistance because I still coming up empty on how to open up a text file and replace some words then save it as another name.
View 3 RepliesI am using the following code, but cannot get this to work. I have got it to work if the replacement is just of one word. So if the word test is replaced by mouse and the only thing in the file is the word test, it works.
How can I replace like this:
CH_IPVOD_filename.mpg > replace the CH_IPVOD_ with nothing for the result of:
filename.mpg
?
I would like to replace every instance of ch_ipvod_ with nothing.

View 7 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 a text file which contain 149000 Words 1 Word Per LineI want to Search Words Who end with "sd" or something else i am using a listbox in which i load all text and then search for it i don't want to know how to search directly from text file listbox method take too much time?

How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?

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.

I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

View 1 RepliesAnyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
