Performing a search on the different search engines
WEBDEV - Server codePHPAjax
The following code is used to perform a search on the different Internet search engines.
// URL that must be queried
sURL is string
 
// Parameters to pass (in "get")
sParameters is string
 
// Result of request
sResult is string
 
// Value that must be found by the engine
sSearchValue is string
 
// Name of the "agent": "Mozilla/4.0...." to simulate IE
sAgentName is string = "Mozilla/4.0 (compatible; MSIE 6.0; Win32)"
sSearchValue = "PCSOFT WINDEV WEBDEV"
// Replace the space characters by +
sSearchValue = Replace(sSearchValue, " ", "+")
// OR replace the space characters by %20
// GOOGLE case:
// sURL = "http://www.google.com/search"
// sParameters=StringBuild("q=%1&start=0", sSearchValue)
// DIR case
// sURL = "http://www.dir.com/cgi/search"
// sParameters = StringBuild("qry=%1&submit=New+search", ...
// sSearchValue) + CR
// NOMADE case
// sURL = "http://search.nomade.tiscali.fr/search.asp"
// sParameters=StringBuild("MT=%1t&s=%1&opt=0", sSearchValue)
// YAHOO case
// sURL = "http://fr.search.yahoo.com/search/fr"
// sParameters=StringBuild("p=%1&n=10", sSearchValue)+CR
// Retrieve the result page further to an HTTP request
// with the parameters in command line
IF HTTPRequest(sURL+"?" + sParameters, sAgentName) = False THEN
Error(ErrorInfo())
ELSE
// To view the result in an HTML control
sResult = HTTPGetResult(httpResult)
TEXTCTRL = sResult
HTMLCTRL = sResult
// Don't assign the URL to the HTML control,
// but the HTML code only.
// Therefore, the "current" directory is not the site directory
// The images and the scripts will not be found
END
Calling an HTTP request

FileID is int

// Open the "C:\MyImages\Images.GIF" file
FileID = fOpen("C:\MyImages\Images.GIF", foCreate)
IF FileID <> -1 THEN
// Retrieve the image
ResCall = HTTPRequest("http://www.windev.com/img/decor/block-t-l.gif")
IF ResCall = True THEN
// Save the image in the file
fWrite(FileID, HTTPGetResult(), ...
