Convert Javascript to work in vb6.0

How can I use the microsoft script control to get the result of this java script to show in a text box?

Code:

Way too advanced PHP for me, sry :)

Looks more like Java Script. Why do you call it PHP?

Exactly how do you want it to work with VB6? Do you want to be able to run that script within your VB6 application? Do you have control over the script code (ie, is this your page or is it a page from some website you have no control over)? What's with the lines in red?

try adding a script control to your form then try evaluating the script in the script control

My mistake, Is it javascript, is it possible to set the webbrowser1 html to that code with out navigating to a webpage and execute the script? I couldn't figure out the script control.

Friendly bump, Edited my question.

OK, here's how you do it.

On a VB Form add a Script control. It is in Components under Microsoft Script Control 1.0

Add two Command buttons
Add a Textbox

Copy and Past the below code to your project

Code:

---

Private Sub Command1_Click()
 Dim InputData As String

 Open App.Path & "\JavaScript.txt" For Binary As #1

 InputData = String(LOF(1), 0)
 Get #1, 1, InputData
 Close #1

 Text1.Text = InputData
End Sub

Private Sub Command2_Click()
  ScriptControl1.Language = "JavaScript"
  ScriptControl1.Reset
  ScriptControl1.Timeout = NoTimeout
  ScriptControl1.AddObject "Any text you want", Me, True
  ScriptControl1.AddCode Text1.Text
  ScriptControl1.Run "begin"
End Sub

Public Sub ShowAnswerInVBApplication(s As String)
  '
  ' This sub is called by the Java script in function 'begin'
  '
  MsgBox s
End Sub

---

Now change the Java script code you have from your post #1 to the following:

Code:

---

function begin()
{
  //
  // This function was added so that the Java Script can work in
  // a Visual Basic application. 
  var hc = 0 + parseInt(1234) % 123431 + parseInt(1234) % 123431;

  //
  // Call the Public Sub in the Visual Basic application passing it the answer
  //
  ShowAnswerInVBApplication(hex_sha1("" + hc));
}

function hex_sha1(s)
{
  return binb2hex(core_sha1(str2binb(s),s.length*8));
}

function core_sha1(x, len)
{
  x[len>>5]|=0x80<<(24-len%32);
  x[((len+64>>9)<<4)+15]=len;
  var w=Array(80);
  var a=1732584193;
  var b= -271733879;
  var c= -1732584194;
  var d=271733878;
  var e= -1009589776;
  for(var i=0;i<x.length;i+=16)
  {
    var olda=a;
    var oldb=b;
    var oldc=c;
    var oldd=d;
    var olde=e;
    for(var j=0;j<80;j++)
    {
      if(j<16)
      {
        w[j]=x[i+j];
      }
      else
      {
        w[j]=((w[j-3]^w[j-8]^w[j-14]^w[j-16])<<1)|((w[j-3]^w[j-8]^w[j-14]^w[j-16])>>>(32-1));
      }
      var y2=(j<20)?1518500249:(j<40)?1859775393:(j<60)? -1894007588: -899497514;
      var t=safe_add(safe_add((a<<5)|(a>>>(32-5)),sha1_ft(j,b,c,d)),safe_add(safe_add(e,w[j]),y2));
      e=d;
      d=c;
      c=(b<<30)|(b>>>(32-30));
      b=a;
      a=t;
    }
    a=safe_add(a,olda);
    b=safe_add(b,oldb);
    c=safe_add(c,oldc);
    d=safe_add(d,oldd);
    e=safe_add(e,olde);
  }
  return Array(a,b,c,d,e);
}

function sha1_ft(t,b,c,d)
{
  if(t<20)
  {
    return(b&c)|((~b)&d);
  }
  if(t<40)
  {
    return b^c^d;
  }
  if(t<60)
  {
    return(b&c)|(b&d)|(c&d);
  }
  return b^c^d;
}

function safe_add(x,y)
{
  return((x>>16)+(y>>16)+((x&0xFFFF)+(y&0xFFFF)>>16)<<16)|((x&0xFFFF)+(y&0xFFFF)&0xFFFF);
}

function str2binb(str)
{
  var bin=Array();
  var mask=(1<<8)-1;
  for(var i=0; i<str.length*8; i+=8)
  {
    bin[i>>5]|=(str.charCodeAt(i/8)&mask)<<(32-8-i%32);
  }
  return bin;
}

function binb2hex(binarray)
{
  var hex_tab=0?"0123456789ABCDEF":"0123456789abcdef";
  var str="";
  for(var i=0; i<binarray.length*4; i++)
  {
    str+=hex_tab.charAt((binarray[i>>2]>>((3-i%4)*8+4))&0xF)+hex_tab.charAt((binarray[i>>2]>>((3-i%4)*8))&0xF);
  }
  return str;
}

Enjoy!

If you want to run the script in a WebBrowser then all you need to do is to add a WebBrowser control to your Form and a Command button.

The script code as you show it in your post #1 remains unchanged but save it as a file and give it a file name like script_test.html

In the Command click event just do this

Code:

---

Private Sub Command1_Click()
 WebBrowser1.Navigate App.Path & "\script_test.html"
End Sub

---

Only problem is when doing it this way you cannot get back the answer in your VB application unless you add some more code which I will show you if you are interested.

I love you guys ;), Gonna try both now.. Thanks!

Yes I do but I am not going to tell you what it is:bigyello:

Seriously, no one on vbforums charges for help they give (or they shouldn't).

I help you and anyone I can if I can; just for the benefit of being able to do so. That's my reward:)

Your to modest. I searched everywhere trying to get it to work. Thanks again :)

Not modest; it's the reason for this forum and it's members.
