Hello everyone,
Does anyone know about ActiveXObject(“ADODB.Stream”)?I need to use it to get web data for my project,what I know the Microsoft jscript(.js) can do it ,and I have an example,I am going to try convert it to maxscript,but 3dsmax does not work for the codes:
Jscript original codes:
var oXmlHttp = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
oXmlHttp.open("GET","https://www.yahoo.com", false);
oXmlHttp.send()
var oStream = new ActiveXObject("ADODB.Stream");
{
oStream.Type=1;
oStream.Mode=3;
oStream.Open() ;
oStream.Write(oXmlHttp.responseBody);
oStream.Position= 0;
oStream.Type= 2;
oStream.Charset="gb2312";
var result= oStream.ReadText();
oStream.Close();
oStream = null;
WScript.Echo( result);
}
The codes I was translated,cause error
(
rollout httpSock "httpSock" width:0 height:0 (activeXControl port "Microsoft.XMLHTTP" setupEvents:false releaseOnClose:false);
createDialog httpSock pos:[-100,-100];destroyDialog httpSock;
oXmlHttp= httpSock.port
oXmlHttp.open "GET" "https://www.yahoo.com" false
oXmlHttp.send();
rollout httpSock "httpSock" width:0 height:0 (activeXControl port "ADODB.Stream" setupEvents:false releaseOnClose:false);
createDialog httpSock pos:[-100,-100];destroyDialog httpSock;
oStream = httpSock.port
if oXmlHttp.readyState==4 then
(
oStream.Type=#adTypeBinary
oStream.Mode=#adModeWrite
oStream.open();
oStream.Write oXmlHttp.responseBody; -- Runtime error: Unable to place variant into OLE SAFEARRAY: Bad variable type.; value: 3P <<
oStream.Position= 0;
oStream.Charset="gb2312"; -- Runtime error: Cannot set the property, .Charset <<
result= oStream.ReadText(); -- Runtime error: ComObject method call failed, ReadText() <<
oStream.Close();
oStream =undefined;
print result
)
)
why do you need exactly ADODB.Stream? you can use .net FileStream, can’t you?
I tried,I used (dotNetClass “system.Net.WebRequest”),sometimes not response even I can visit url site normally,is the “.net FileStream” as same as dotNetClass “system.Net.WebRequest”?Is there an example?
ADODB.Stream is just a pretty old thing for stream reading/writing… depending on what you want to read/write you can use StreamReader/StreamWriter or FileStream.
what do you want to read or write?
I just want to read text of a url line such as:(Only read function)
http://en.wikipedia.org/wiki/Text
the whole text(html format is ok)
I want to store necessary data for my website,and then read it from maxscript
I got an example,is this way right?why I got txt=”” after run?
url="http://en.wikipedia.org/wiki/Text"
wc=dotNetClass "System.Net.WebClient"
sr=dotNetClass "System.IO.StreamReader"
wcobj=(dotNetObject wc)
wcobj.Headers.Add "user-agent:xxx"
stm=wcobj.OpenRead url
srobj=dotNetObject sr stm
txt=srobj.ReadToEnd()
srobj.Close()
print txt
