Reading from a text file

mp3guy

How can I tell VB to read characters from a text file? The characters are separated by a comma, and are varible in length. Like:

1223A,AD43B,D45C,D43,DAC54,ADCBA4

how can I get one of these values at a time, so I can read the first set of characters, use them, then go onto the next set?

in B it's

do
input #1,A$
loop until EOF(1)

hint A$ = " a string"

The answer to this is simple. My solution is in c#, so you can port it easily (i don't code vb that much) Do it like so:

char c = ',';
string sentence;
string[] s;
sentence = "1223A,AD43B,D45C,D43,DAC54,ADCBA4";
s = sentence.Split(c);

s will be populated with 1223A being in s[0], AD43B being in s[1] and so on.

thanks, i got it to work, with:

dim mystring as string
Do Until EOF(1)
input #1, mystring$
loop

Unfortunately it's not obvious that you have already googled it.

If you come looking for help from people you should be a little more respectful. If someone says GTFW and they frequently answer questions then it's likely that they have good reason. It's also more than likely how you asked the question rather than what you asked.

You should read the charter and in particular read:
HOW TO ASK A QUESTION

BTW look up the Scripting.FileSystemObject and Scripting.TextStream object for reading in a marginally more object oriented manner.

First check on google

http://www.builderau.com.au/program/windows/0,39024644,20267367,00.htm

http://www.experts-exchange.com/Programming/Programming_Languages/Visual_Basic/Q_20941478.html

Or you could of searched this forum as I am sure the same question has been asked more then once.

Failing that the VB help screens should of been able to tell you (unless they removed sample code from it now?)

I wasted eight seconds of my time clicking the thread and reading it. I’m not getting those eight seconds back. If no one slaps him down two things will happen; he’ll never learn to STFW before posting and he’ll continue posting STFW/RTFM type questions on this and other boards.

Now imagine, as often happens when we get a new crop of noobs starting CS courses every autumn, that he’s not the only one who asks such questions. Within a short while, half of the threads would end up a similar waste of our time. I’ve seen entire mailing lists and bulletin boards abandoned because no one was willing to police the signal to noise ratio.

In short, flaming teaches people to look before they leap.
