Hi,
I get the "The data area passed to a system call is too small" error on my
HttpOpenRequest call. The program works fine on my local machine but if I
copy it to the server where it should run I get this error.
fuction doCall( const aUrl : String ) : String;
var
hSession, hHostConnection, hDownload: HINTERNET;
Buffer: PChar;
dwBufLen, dwIndex, dwBytesRead, dwTotalBytes: DWORD;
HasSize: Boolean;
Buf: array [0..1024] of Byte;
l_stream : TStream;
l_strStream : TStringStream;
begin
//open the connection to the internet
hsession := InternetOpen(PChar(''), INTERNET_OPEN_TYPE_DIRECT, nil, nil,
0);
if hSession = nil then
begin
Result := SysErrorMessage(GetLastError);
Exit;
end;
// Connect to the host
hHostConnection := InternetConnect(hSession, PChar(aUrl), 0, nil, nil,
INTERNET_SERVICE_HTTP, 0, DWORD(0));
if hHostConnection = nil then
begin
Result := 'Error in connection';
Exit;
end;
//Request the file
hDownload := HttpOpenRequest(hHostConnection, 'GET', PChar(''),
'HTTP/1.0',
PChar(''), nil, INTERNET_FLAG_RELOAD or INTERNET_FLAG_PRAGMA_NOCACHE,
0);
if hDownload = nil then
begin
Result := 'Could not download ' + SysErrorMessage(GetLastError);
Exit;
end;
//Send the request
HttpSendRequest(hDownload, nil, 0, nil, 0);
Could anybody assist in sorting out this error?
Thanks VERY much
Francois
