View 1 RepliesI'm building a program in which it asks for your name and age and determines a ticket price based upon these details. I want it to show the person's name, then their age, (jump down a line) then their ticket price, and then it jumps down a line to show the next person's name, age and ticket price. Issue is, when it's meant to jump down to show the next person, it just completely deletes the last person's details.I'm using this line of code:
TxtFareShow.Text = (Name & Age & vbCrLf & Price) & vbCrLf
How do I fix this?
What I basically have is a small game which I want to count wins/loss/ties. I have no problem with the game aspect but need to know how I can replace a string in a csv file. IE: If Jim wins the game, his 5 needs to be turned to a 6. After googling quite a while I came across the replace() function, but it doesn't actually rewrite it back to the text file
Contents of users.txt:
Jim,1.jpg,5,1,0

The issue I have, is if I try to use any sort of IO function after this (WriteAllLines, streamwriter, etc) - I get a process is being used and can't touch the file (because its being read).Must I somehow create a new file with a copy of everything including the replaced string?
I 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 6 RepliesI have some large csv files (1.5gb each) where I need to replace specific values. The method I'm currently using is terribly slow and I'm fairly certain that there should be a way to speed this up but I'm just not experienced enough to know what I should be doing. This is my first post and I tried searching through to find something relevant but didn't come across anything.
My other thought would be to break the file into chunks so that I can read the entire thing into memory, do all of the replacements there and then output to a consolidated file. I tried this but the way I did it actually ended up seeming slower than my current method.

Replacing text with AutoText entries in Word 2007 using VB.NET
View 1 RepliesI am trying to do this but it doesn't work:
VB
Dim str As String = "07" & GetBetween("Stephen 0761234567", "07", vbNewLine)Dim op As String = "lol" TextBox1.Text.Replace(str, op)
GetBetween is just a function to match something between something else. That works fine, the string (str) sets as 0761234567 just like I want but when i try to replace the text it doesn't work.
I'll explain the scenario. I have a list containing character list and it's corresponding unicode characters(copied from CharMap and pasted in VB editor).
For example:
Text = Unicode --> Unicode character

K = U+004A --> J

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:

So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
