Url Parsing VFP

[louie728]

Hello all,

I am developing an application that will send via a url querystring a path to a file for upload to a webpage. (example:

http://www.example.com?path=c:\path)

The path will have spaces because it will be sending files from the users my documents folder, right now I am just using STRTRAN to replace spaces with "%20", but would like to know if there is some built in routine or if someone knew of one that I could use for url parsing.

Any help is greatly appreciated......

louie728,

I'm not sure, but my guess is that your STRTRAN() solution would be the fastest and easiest way of doing this.

In general, you could simply parse the string and convert any characters outside a given range to it's hex equivalent. Something like this should work:

* ConvURL.PRG
LPARAMETERS p_cURL
#DEFINE cLowASCII 33 && greater than Space
#DEFINE cHighASCII 126 && less than DEL
LOCAL l_cResultURL, l_cChr

l_cResultURL = ""
FOR lnii = 1 TO LEN(p_cURL)
   l_cChr = SUBSTR(p_cURL, lnii, 1)
   IF !BETWEEN(ASC(l_cChr), cLowASCII, cHighASCII)
      l_cChr = "%"+RIGHT(TRANSFORM(ASC(l_cChr), "@0"),2)
   ENDIF
   l_cResultURL = l_cResultURL + l_cChr
ENDFOR

RETURN l_cResultURL

*EOP: ConvURL.PRG
