Have a look at Adam Vieweger/s article
"How to post data using TCppWebBrowser in C++Builder".
http://community.borland.com/article/0,1410,27519,00.html

Just saying it doesn't work says nothing about the actual problem you are
having.  Please show your actual code.  How do you know what data the server
is expecting in the first place?

I never thought that make an Post was so hard....

I have tried with
    TVariant Datos = "usuario=paco123&password=paco123";
    MyTccpWebBrowser -> Navigate
(http://www.iberware.com/enercut/parametros.php",NULL,NULL,Datos);

    The url is the real url, and the usuario and password are real too. this
pages is made only for try, and it show in screen the
parametros that catch with Get. Is written in asp

I try with with this code too.

void WebPostData(TCppWebBrowser *CppWebBrowser, String sURL, String
sPostData)
{
  BSTR bstrHeaders = NULL;
  TVariant vFlags = {0}, vTargetFrameName={0}, vPostData={0}, vHeaders={0};
  LPSAFEARRAY psa;
  LPCTSTR cszPostData = sPostData.c_str();
  UINT cElems = lstrlen(cszPostData);
  LPSTR pPostData;
  LPVARIANT pvPostData;

  bstrHeaders = SysAllocString(L"Content-Type:
application/x-www-form-urlencodedrn");
  if (!bstrHeaders){
    Application->MessageBox("Could not allocate bstrHeaders", "Warning",
MB_OK | MB_ICONWARNING);
    return;
  }

  V_VT(&vHeaders) = VT_BSTR;
  V_BSTR(&vHeaders) = bstrHeaders;

  pvPostData = vPostData;

  if(pvPostData){
    VariantInit(pvPostData);

    psa = SafeArrayCreateVector(VT_UI1, 0, cElems);
    if(!psa){
      return;
    }

    SafeArrayAccessData(psa, (LPVOID*)&pPostData);
    memcpy(pPostData, cszPostData, cElems);
    SafeArrayUnaccessData(psa);

    V_VT(pvPostData) = VT_ARRAY | VT_UI1;
    V_ARRAY(pvPostData) = psa;
  }

   CppWebBrowser->Navigate((TVariant)sURL, &vFlags, &vTargetFrameName,
&vPostData, &vHeaders);
}

but send noting..

is impossible to pass two string ?

But you did not show how you called WebPostData() especially
the contents of String sURL. That looks important to me as you
will in one way or the other have to format that String for
different key-value pairs.

The problem for you is that Adam Vieweger in his article
does not show how that has to be done too.

As you will not be the first to try his code you may
expect some comments already. Go to the page again and use
the "View comments" link at the bottom of the page.

If you succeed then please inform us how.

Hans.

I just call
WebPostData(MtWebControl,http://www.iberware.com/enercut/parametros.php,"act
ion=LogMeIn&usuario=paco123&password=paco123");
I have tried without   action=LogMeIn too, but nothing
You can try it because the page is only for this.

Think that "action=LogMeIn" is not done in this way.

Tried it with the following html page.

<html>
<body>
    <form method="post" action 
="http://www.iberware.com/enercut/parametros.php">
      <input name="action" value="LogMeIn">
      <br>
      <input name="usuario" value="paco">
      <br>
      <input name="password" value="123456">
      <input type="Submit" value="Submit form">
    </form>
   <br>
    <form method="post" action 
="http://www.iberware.com/enercut/parametros.php">
      <input name="usuario" value="paco">
      <br>
      <input name="password" value="123456">
      <input type="Submit" value="Submit form">
    </form>
   <br>
    <form method="post" action 
="http://www.iberware.com/enercut/parametros.php?LogMeIn">
      <input name="usuario" value="paco">
      <br>
      <input name="password" value="123456">
      <input type="Submit" value="Submit form">
    </form>
   <br>
    <form method="post" action 
="http://www.iberware.com/enercut/parametros.php/LogMeIn">
      <input name="usuario" value="paco">
      <br>
      <input name="password" value="123456">
      <input type="Submit" value="Submit form">
    </form>
   <br>
   <form method="get" action 
="http://www.iberware.com/enercut/parametros.php">
      <input name="usuario" value="paco">
      <br>
      <input name="password" value="123456">
      <input type="Submit" value="Submit form">
    </form>
</body>
</html>

The page demands the post method. That's for sure.

I did not try with Adam's code.

Why did you not react on my suggestios
for the "View comments" link in the article ?

HAns.

it works fine.....

there was two   \\      that was missing  , in the Headers , but the code of
Adam really works.

Thank you very mach.

Now just have My other big problem:

        I can not send one text file to the USB port, ( is for cutting in a
plotter), in parallel port OK, but not in USB...

well it is another story....
