Hi
I got some doubts with the PaintWeb integration

1) Is it possible to integrate PaintWeb with classic ASP projects or
any asp.net projects
2) I tried to integrate it with my classic ASP project and I got error
message like " Demo: PaintWeb initialization failed." and " Error:
Failed loading the configuration file."

Could you please help me to integrate it with my classic ASP web
application. I tried to run the demo from my site and it also shows
the same error message.


Following is the sample code that I used from your site


<!DOCTYPE html>
<html lang="en">
<head>

<title>PaintWeb simple demo</title>


<!-- $URL: http://code.google.com/p/paintweb $
$Date: 2010-06-26 22:58:27 +0300 $ -->
</head>
<body>

<p><img id="editableImage" src="PaintWeb/demos/freshalicious.jpg"
alt="Freshalicious"></p>

<p><button id="buttonEditImage">Edit image!</button></p>

<div id="PaintWebTarget"></div>

<script type="text/javascript" src="PaintWeb/build/paintweb.js"></
script>

<script type="text/javascript"><!--
(function () {
// Function called when the user clicks the "Edit image" button.
function pwStart () {
document.body.insertBefore(loadp, btn.parentNode);

timeStart = (new Date()).getTime();


pw.init(pwInit);
//alert (pw.config.configFile);
};

// Function called when the PaintWeb application fires the "appInit"
event.
function pwInit (ev) {
var initTime = (new Date()).getTime() - timeStart,
str = 'Demo: Yay, PaintWeb loaded in ' + initTime + ' ms! ' +
pw.toString();

document.body.removeChild(loadp);

if (ev.state === PaintWeb.INIT_ERROR) {
alert('Demo: PaintWeb initialization failed.');
return;

} else if (ev.state === PaintWeb.INIT_DONE) {
if (window.console && console.log) {
console.log(str);
} else if (window.opera) {
opera.postError(str);
}

} else {
alert('Demo: Unrecognized PaintWeb initialization state ' +
ev.state);

return;
}

img.style.display = 'none';
btn.style.display = 'none';
};

var img = document.getElementById('editableImage'),
btn = document.getElementById('buttonEditImage'),
target = document.getElementById('PaintWebTarget'),
loadp = document.createElement('p'),
timeStart = null,

// Create a PaintWeb instance.
pw = new PaintWeb();

pw.config.guiPlaceholder = target;
pw.config.imageLoad = img;
pw.config.configFile = 'config-example.json';
loadp.appendChild(document.createTextNode('Loading, please
wait...'));


if (btn.addEventListener) {
btn.addEventListener('click', pwStart, false);
} else if (btn.attachEvent) {
btn.attachEvent('onclick', pwStart);
} else {
btn.onclick = pwStart;
}
})();
--></script>

</body>

Hi,
 
I have the same issues and initialization errors. Was there ever a resolution to this? If so, can you post it? I'm using classic ASP on IIS 7.5. Thanks.

Try this:
the settings are as follows: 

IIS7 configuration to support JSON


IIS7 configuration to support JSON:
Using IIS manager: clock on IIS server (the main node on the left - where you see the machine name)
  1. Add ‘json’ MIME Type
  • Double click on ‘MIME Types’ icon
  • Click ‘Add…’ link (under Actions section on the right side)
  • In ‘Add MIMI Type’ window type:
File name extension: .json

2. Add Script Map Handler for ‘json’ MIME Type
  • Double click on ‘Handler Mappings’ icon
  • Click on ‘Add Script Map…’ link (under Actions section on the right side)
  • In ‘Add Script Map’ window type:
Request path: *.json
Executable: C:\Windows\System32\inetsrv\asp.dll
Name: JSON
  • Click OK (Message box pops up with a message: Do you want to allow this ISAPI extension?...etc ) Click Yes, You should see the .json extension added to the list of the Handler Mappings list

IIS6 configuration to support JSON:
Using IIS manager
  1. Add ‘json’ MIME Type
    • On the main IIS server right click and select ‘Properties’
    • From ‘Properties’ window in ‘MIME Types’ section click on ‘MIME Types’ button.
    • From ‘MIME Types’ window click on ‘New…’ button
    • In ‘MIME Type’ window type:

- Click on ‘Configuration…’ button.
- From ‘Application Configuration’ window select ‘Mappings’ tab if not selected.

- Click ‘OK’ to ‘Application Configuration’ window this will open ‘Inheritance Overrides’ window click ‘OK’ then click ‘OK’ on the Properties window. 
Important Note:
Make sure you have Active Server Pages Allowed in the Web Service Extensions section of your IIS configuration.
IIS6:
IIS6 Manager -> (local computer) -> Web Service Extensions -> Active Server Pages
Then click ‘Allow’ button.


IIS7:
1. from IIS7 manager click on the computer name item on the left 
2. click on “ISAPI and CGI Restrictions” icon (in IIS section) 
3. the “ISAPI and CGI Restrictions” window will show then make sure the ‘Restriction’ for ‘Active Server Pages’ is ‘Allowed’

I hope this will solve your problem. have a nice day.

Dhanashri,
 
Thank you for this. Your instructions are the resolution to the ASP problem. The issue was JSON mime type and handler not being set in IIS as ASP was already enabled.  Paintweb now works on my IIS 7.5 server.
 
Best regards.
