Issues masking a password in VB

I have written some code in VB script that does not always present the same dialog box. The attached code should prompt for a password and not allow a blank password. Then prompt to confirm that password, again not allowing a blank. Then compare the 2 and loop if they do not match, or (remarked out) change the password of the stated user (pphread).

the issue I have is that when executed I get a dialog box stating "Please enter the new password for Pphread.". I enter a password and then I should get a prompt stating "Please confirm the password for Pphread.".

Sometimes I get the confirmation prompt and sometime I get just a blank dialog box with a text box and submit button. No text stating "Please confirm the password for Pphread."

It appears to be random as to when it is correct and when it is not.

I have attached the code and a picture of the blank dialog box.

Any suggestions would be great.

Currently testing on Windows 7/64bit w/IE10, but will need to run on Windows XP SP3 32bit w/ IE9

thanks

Very strange indeed. I have confirmed the behaviour on W7/64,IE10/32. It may be a bug, I haven't been able to establish the reason behind it ("F12 dev tools" shows the text is actually there but invisible) but I did find a solution I think.

It works consistently for me (with a reasonable amount of testing) after changing WriteLn to Write (only the last one I left alone) so it seems the linefeeds in between the html tags are messing with the document somehow:
      .Write("<html><body bgColor=Silver><center>") 
      .Write( sTitle ) 
      .Write("<input type=password id=pass>  " & _ 
               "<button id=but0>Submit</button>") 
      .WriteLn("</center></body></html>") 

Open in new window

It works the same as concatenating the string all into one Writeln.
      .WriteLn("<html><body bgColor=Silver><center>" & sTitle & "<input type=password id=pass>  " & "<button id=but0>Submit</button>" & "</center></body></html>")

Of course you will still need to test on IE9 anyway, I haven't got that version available.

robert_schutt I have given you the credit seeing as you came up with the fix. Now I have to enter another question because the script does not work on Windows XP. The line:

<code>Set user = GetObject("WinNT://" & strComputer & "/" & strUser & ",user") </code>

Causes Windows XP to error with:

You were not connected because a duplicate name exists on the network. Go to Control Panel and change the computer name and try again.

I will be posting another question to see if this can be fixed. Thank s for this fix.

Pphread

The error is false as the computer name is not a duplicate.
