Help I need help

[Sophie]

CString string= "http://home.microsoft.com?RID=Report1&Date=today";
int len = string.GetLength();
while(len>0)
{
int pos = string.Find("?");
if(pos>0)
{
int i =0;
CString URL = string.Mid(0, pos);
int pos2 = string.Find("=");
int pos3 = string.Find("&");
CString string2 = string.Mid(pos2, 8);


}
}

What I want is to find what is inbetween '=' & '&'. I can find "Report1" but than I can't find "today"

If someone can show me what I'm doing wrong...

Thank you

try like this :

CString string= "home.microsoft.com?RID=Report1&Date=today";
int pos = string.Find("?");
if(pos>0)
{
CString URL = string.Mid(0, pos);
string = string.Mid(pos);
len = string.GetLength();
while(len>0)
{
int pos2 = string.Find("=");
int pos3 = string.Find("&");
if (pos3 == -1)
CString string2 = string.Mid(pos2, pos3);
else
CString string2 = string.Mid(pos2);
string = string.Mid(pos3);
len = string.GetLength();
}
}



if i understand what you want to do... it will be ok..

sorry.. i make 1 error in last..
now its good :

CString string= "home.microsoft.com?RID=Report1&Date=today";
int pos = string.Find("?");
if(pos>0)
{
CString URL = string.Mid(0, pos);
string = string.Mid(pos);
len = string.GetLength();
while(len>0)
{
int pos2 = string.Find("=");
int pos3 = string.Find("&");
if (pos3 != -1)
{
CString string2 = string.Mid(pos2, pos3);
string = string.Mid(pos3);
len = string.GetLength();
}
else
{
CString string2 = string.Mid(pos2);
len = 0;
}
}
}

CString string = "http://home.microsoft.com?RID=Report1&Date=today";
int len = string.GetLength();
if (len > 0) // use if instead of while, or we have an infinte loop
{
int pos = string.Find("?");
if(pos>0)
{
int i =0;
CString URL = string.Mid(0, pos);
int pos2 = string.Find("=");
int pos3 = string.Find("&");
// use pos2 + 1, because CString's are 0
CString string2 = string.Mid(pos2 + 1, pos3 - pos2 - 1); based
int pos4 = string.ReverseFind('=');
CString string3 = string.Right (len - pos4 - 1);
}
}

To find the last part of the string (the "today" part), you just need to find the '=' and grap all the characters after that up to the end. I found the '=' sign by using CString::ReverseFind, & then took the remaining characters with CString::Right.

If the code doesn't make sense to you, or if you have any more questions, send me a private message or just respond to this message.

This works great for that string but what if a parameter was added such that
CString string = "http://home.microsoft.com?RID=Report1&Date=today&Date2=today2";

Thanks

loop like i said... but change values for .Mid()
