}
//return the position of the first occurrence of one
string "searchString" within another "txt"
//return -1 means cannot find

Answer / majhoul
int Instr(int start,string string1,string string2,string type-of-the-test)
{
lenght= string2.lenght();
int lenght ;
int i ;// as counter for lenght
if (string1==NULL ll string2==Null)// to check that the
both of the strings
is not empty
return 0;
if (type-of-the-test = "text")// it doesn't matter if it is upper or lower case in the text test !!!
{
string1=toupper(string1) ;
string2=toupper(string2) ;
}
int location = string1.find(string2);
while (location != string::npos)//
{
if (location > start) // the string was found we have to check if it is match the type the test
{
i=0 ;
while ( lenght > 0 )
{
if (string1[location+i]!= string2[i] )
break ;// return where the string was found
}
if ((lenght-1) == i)
return location ;
}
else
location = string1.find(string2,location+1)
}
return 0 ; // if the string wasn't find at all [p
}
' String to search in.
string SearchString = "XXpXXpXXPXXP"
string SearchChar = "P"
TestPos = InStr(4, SearchString, SearchChar,"Text")
' A binary comparison starting at position 1. Returns 9.
TestPos = InStr(1, SearchString, SearchChar,"binary")
//' If Option Compare is not set, or set to Binary, return //9.
//' If Option Compare is set to Text, returns 3.
//TestPos = InStr(SearchString, SearchChar)
//' Returns 0.
//TestPos = InStr(1, SearchString, "W")
