Hello i'm frenche sorry for my english

I use your UDF to post a file on dl.free.fr. with success. and a _IECreateEmbedded().

But in the end of proccess, the server send me a webpage that containt an URL to delete the file and other. When i click on an URL it crashes.

exit code in Scite: !>14:50:03 AutoIT3.exe ended.rc:-1073741819

Some idea, problem with _IENaviagte() or UDF ???

Anything is possible, but I don't see how it could be affected by some used function from WinHTTP.au3.

...String returned by _WinHttpQueryOption($hRequest, $WINHTTP_OPTION_URL) is null terminated for sure, even more than it should be (lol).

Can you post Encode_MultiPart_FormData() function too? Why aren't you reading in binary mode?

Btw, nice script.

Can you post Encode_MultiPart_FormData() function too? Why aren't you reading in binary mode?

I think, it's from my UDF: http://www.autoitscript.com/forum/index.ph...st&p=610967

GaRydelaMer · April 16, 2009

Hello Thx for reply

@ ProgAndy: Yes i use you're function Encode_MultiPart_FormData()

I don't thing it was null termainating in "_WinHttpQueryOption($hRequest, $WINHTTP_OPTION_URL)"

I look fine the WebPage and she's refresh along the server want's to scan the file.

But i can't click on links !!! AuToIt Crash !!! The problem it's with IE object perhaps ?

I have this text in the console.

Hi everybody,

I have problems downloading larger binary files, like images.

$hw_open = _WinHttpOpen("WinHTTP Example")

$hw_connect = _WinHttpConnect($hw_open, "192.168.2.2")
$h_openRequest = _WinHttpOpenRequest($hw_connect, "GET", "/image.gif", "HTTP/1.1")
_WinHttpSendRequest($h_openRequest)
_WinHttpReceiveResponse($h_openRequest)

If _WinHttpQueryDataAvailable($h_openRequest) Then
    $rData = _WinHttpReadData($h_openRequest, 2, 1000000 )
    ConsoleWrite( "Len: " & BinaryLen( $rData ) & @CRLF )
EndIf
_WinHttpCloseHandle($h_openRequest)
_WinHttpCloseHandle($hw_connect)
_WinHttpCloseHandle($hw_open)
Exit

The Image is around 33kB and it takes roughly 10 seconds until the ConsoleWrite output appears.

In Wireshark I can see that the request is served within a couple of milliseconds.

Debugging showed my that the ReadData call takes the most time.

Is there something I am missing?

Thanks

aboy

GaRydelaMer · April 17, 2009

Hi

Try this ^_^

Global $hw_open = _WinHttpOpen("WinHTTP Example")

Global $hw_connect = _WinHttpConnect($hw_open, "localhost")
Global $h_openRequest = _WinHttpOpenRequest($hw_connect, "GET", "/css/images/banniere_fixe_zazouminiwebserver.jpg", "HTTP/1.1")
_WinHttpSendRequest($h_openRequest)
_WinHttpReceiveResponse($h_openRequest)

If _WinHttpQueryDataAvailable($h_openRequest) Then
    Global $rData = _WinHttpReadData($h_openRequest, 2), $temp
    While 1
        $temp = _WinHttpReadData($h_openRequest, 2)
        If BinaryLen($temp) = 0 Then ExitLoop
        ConsoleWrite("Len 1: " & BinaryLen($temp) & @CRLF)
        $rData = _WinHttpBinaryConcat($rData, $temp)
    WEnd
    $temp = ""
EndIf
ConsoleWrite("Total Len: " & BinaryLen($rData) & @CRLF)

_WinHttpCloseHandle($h_openRequest)
_WinHttpCloseHandle($hw_connect)
_WinHttpCloseHandle($hw_open)
Exit

ProgAndy · April 17, 2009

I found out, that _WinHttpBinaryConcat is not needed. You can append a binary Variabel to another with & ^_^

1) Create an empty binary variable:

$Bin = Binary("")

2) Append Binary Data

$Bin &= Binary("0x1254AB")

Edited April 17, 2009 by ProgAndy

GaRydelaMer · April 17, 2009

thx ProgAndy

I never use BinaryString !!

I can write to a file: FileWrite($hFile, $bin_String) ?

Edit:

Yes We Can ^_^

Fantastic

Edited April 17, 2009 by GaRydelaMer

ProgAndy · April 17, 2009

Yes. Open it in Binary (over)write mode and then write Binary data ^_^

aboy · April 17, 2009

Hi guys, thanks for the reply.

It still lags a lot, her is my current loop:

If _WinHttpQueryDataAvailable($h_openRequest) Then
    While 1
        $tempData = _WinHttpReadData($h_openRequest, 2 )
        $rData &= $tempData
        ConsoleWrite("Len 1: " & BinaryLen($tempData) & @CRLF)
        If $tempData = 0 Then 
            ExitLoop 
        EndIf
    WEnd
    ConsoleWrite( "Len total: " & BinaryLen( $rData ) & @CRLF )
EndIf

And that's the Console output:

Len 1: 8192
Len 1: 8192

The output of the last block of data (356bytes) takes really long, the ones before are immediately there.

Thanks

For me.

My WebServer for testing, is ZMWS on my USB Key, Freeware & open source support php and mysql and a custom handler and virtualhosts.

ex: in the configuration file: Handler:bat="C:\\winnt\\system32\\cmd.exe /C"

# The Document Root, where the virtual host files are located

# (absolute or relative to server dir)

# default is _vhosts.zmwsc/domain relative to main server's webdir

# VirtualHost:mycompany.com:webdir=_web.zmwsc/_vhosts.zmwsc/mycompany.com

ZMWS

With a jpg image.

If _WinHttpQueryDataAvailable($h_openRequest) Then
    Global $tempData = Binary("")
    Global $rData = _WinHttpReadData($h_openRequest, 2)
    While 1
        $tempData = _WinHttpReadData($h_openRequest, 2)
        If BinaryLen($tempData) = 0 Then ExitLoop
        ConsoleWrite("Len 1: " & BinaryLen($tempData) & @CRLF)
        $rData &= $tempData
    WEnd
    $tempData = Binary("")
EndIf
ConsoleWrite("Total Len: " & BinaryLen($rData) & @CRLF)

FileWrite("toto.jpg", $rData)

If you look in my console, i haven't this Line: Len 1: 0, because i'm exiting while before you.

I found out, that _WinHttpBinaryConcat is not needed. You can append a binary Variabel to another with &
1) Create an empty binary variable:
$Bin = Binary("")
2) Append Binary Data
$Bin &= Binary("0x1254AB")
$Bin &= Binary("0x1254AB")

Well of course. But that's not documented feature. I never read that one of the devs said you should/could concat two binary datas like that. Help file lacks that information too.

It was mentioned here by some Jon (who the fuc*k is he???) and that was ending with question mark.

Well, i always missed that, but it should be faster than the concat-func and aboy wants his code to be fast ^_^

Okay, so I ran my code and the one from GaRydelaMer

on an other machine (XP in a Parallels VM) and it runs smoothly...

Something must be wrong with my other PC at work. I'll check next Monday.

What I can say is that there are 2 network cards installed, hope that is not a problem...

Thanks for now!

Hi guys,

back at work I tried the code again and still had the lag with the last data call of _WinHttpReadData()

I just found out that the problem is indeed with my network cards. I have an internal one and

an external USB2Ethernet converter. The images are on a device that is connected to the USB2Ethernet converter.

When I remove the converter and request the data from a local running webserver,

the calls return pretty quickly. The same happens when I request data from a webserver

bound to the internal network card.

Any ideas if the winhttp.dll could cause the problems?

ProgAndy · April 20, 2009

I think, your device connected to your USB2Ethernet is not sending the size of the data to receive. Then WinHTTP waits until a timeout occurs, since it doesn't know when the transmission is complete.

This are bad news.. :-(

I tried the http.au3 UDF as well and it is faster but still slow compared to using wget.exe:

$wgetargs = "-O image.gif http://" & "192.168.3.88" & "/image.gif"          
ShellExecuteWait("wget.exe", $wgetargs , "", "", @SW_HIDE )

Works via the file system but that would have been the case with other UDFs

like winhttp.au3 or http.au3 as well... when we talk about binary files.

Thanks anyway,

aboy

@aboy, try running this:

#include <WinHTTP.au3>

Global $hHttpOpen = _WinHttpOpen()
If @error Then
    MsgBox(48, "Error", "Error initializing the usage of WinHTTP functions.")
    Exit
EndIf

Global $hHttpConnect = _WinHttpConnect($hHttpOpen, "192.168.2.2")
If @error Then
    MsgBox(48, "Error", "Error specifying the initial target server of an HTTP request.")
    _WinHttpCloseHandle($hHttpOpen)
    Exit
EndIf

Global $hHttpRequest = _WinHttpOpenRequest($hHttpConnect, "GET", "image.gif")
If @error Then
    MsgBox(48, "Error", "Error creating an HTTP request handle.")
    _WinHttpCloseHandle($hHttpConnect)
    _WinHttpCloseHandle($hHttpOpen)
    Exit
EndIf

_WinHttpSendRequest($hHttpRequest)
If @error Then
    MsgBox(48, "Error", "Error sending specified request.")
    _WinHttpCloseHandle($hHttpConnect)
    _WinHttpCloseHandle($hHttpOpen)
    Exit
EndIf

_WinHttpReceiveResponse($hHttpRequest)

If _WinHttpQueryDataAvailable($hHttpRequest) Then
    ConsoleWrite(_WinHttpQueryHeaders($hHttpRequest))
Else
    ConsoleWrite("! Nothing available." & @CRLF)
EndIf

_WinHttpCloseHandle($hHttpRequest)
_WinHttpCloseHandle($hHttpConnect)
_WinHttpCloseHandle($hHttpOpen)

ProgAndy could be right (as usual ^_^ )

edit:

Don't forget to post console output
