Scanne en tekst for en string

dette er svært viktig for meg å vite.

This example, taken from MSDN assumes that you have read a part of the file into a string variable. You obvioulsy need to loop throught the whole file.

InStr Function Example
This example uses the InStr function to return the position of the first occurrence of one string within another. You should also take a look at help in VB.

Dim SearchString, SearchChar, MyPos
SearchString =\"XXpXXpXXPXXP\"  \' String to search in.
SearchChar = \"P\"  \' Search for \"P\".

\' A textual comparison starting at position 4. Returns 6.
MyPos = Instr(4, SearchString, SearchChar, 1) 

\' A binary comparison starting at position 1. Returns 9.
MyPos = Instr(1, SearchString, SearchChar, 0)

\' Comparison is binary by default (last argument is omitted).
MyPos = Instr(SearchString, SearchChar)  \' Returns 9.

MyPos = Instr(1, SearchString, \"W\")  \' Returns 0.
