assumming test is integer and strText is a string. This should work

test  = strText.Indexof("\t")+1

IndexOf returns an integer with position, not a string, just like InStr. So should be something like:

ListViewItem item = lstMfgColors.SelectedItems[I];
int pos = item.Text.Indexof("\t",0)+1;

Is that what you need?
Maybe some sourcecode around it would be more explanatory...

try this:
- Use a string variable type string:
string segment = str.Substring(index1,len);
where segment is a variable to store the substring,
str is the original string,
index1 is the zero-based starting position of the substring that you want to extract,
len is the number of characters you wish to extract.

This should resolve it.
