Answers

How do I set write permissions on the "temp" folder?

Perl Captcha requires to set write permissions on folder "temp" located in the same directory that the Perl page that process the form.

For Linux/Unix servers

FTP programs ("clients") allow you to set permissions for files and directories on your remote host. This function is often called chmod or set permissions in the program menu.

In the first image, look at the last column - that shows the permissions. It looks a bit confusing, but for now just note the sequence of letters:



Right click the folder or files to set permissions, and usually a popup screen will appear (see the second image):



Don't worry about the check boxes. Just delete the 'Numeric value:' and enter the number you need - in this case it's 777 or simply mark all checkboxes. Then click OK.

That's all.

For Windows servers

There should be an option in your web hosting control panel to set write permissions. If it's not present, you may can contact your web hosting service and request the write permissions for the PHP code.



Some of my fields are not being re-filled when the captcha code entered is incorrect, any solution?

Please do not use spaces in the field names, use underscore _ instead spaces.

Adidtionally, if you are not using spaces, note that in Internet Explorer the "select" fields need the "value" specified in order to be able to refill those fields with javascript.

Example (incorrect):

<select name="my field">
<option>Blue</option>
<option>Red</option>
<option>Green</option>
</select>

Example (correct):

<select name="my_field">
<option value="Blue">Blue</option>
<option value="Red">Red</option>
<option value="Green">Green</option>
</select>

Please add the value attributes to the option tags.



Is it possible to change the return link so that when the page refreshes, it jumps back down to the captcha image instead of the top of the page?

Yes, follow these steps:

1 - Add an empty anchor at the bottom of your page like this one:

<a name="captcha"></a>

2- Add #captcha to the end of your "Redirect on failed" page, example:

mypage.html#captcha


Can I put some sort of reset button to generate a new captcha image (ex: in case the user doesn't see clearly) ?

Yes, put this button into your page:

<input type="button" name="hdwnc" value="new image" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').src+'&'+Date();" />

This link makes the same function:

<a href="#captchaimg" onclick="document.getElementById('captchaimg').src =document.getElementById('captchaimg').src+'&'+Date();">new image</a>


The captcha image is not being displayed. There is a workaround?

First be sure that you uploaded all the files to your online web server.

If the files are already uploaded then open the files "hdwcaptcha.pl", "bmp.pm" and your old Perl file (probably formmail.pl or similar) and remove the -wT parameter at the first line of that files if present.

If the problem persits then please check the file permissions. The "hdwcaptcha.pl" and the "bmp.pm" files must have the same permissions than the old perl file in your server (probably formmail.pl or similar).

Additionally, don't forget to set the correct permissions for the "temp" folder (write permissions are needed only for the temp "folder").


When I double click the MXP file I'm getting this error: "Extension requires more recent version of Macromedia Extension Manager". How can I solve this?

Download the most recent version of the Adobe/Macromedia Extension Manager or the version related to your Dreamweaver version:

http://www.adobe.com/exchange/em_download/

After installed open the MXP file from the Extension Manager menu to be sure that you are installing the extension using the correct Extension Manager.

Do you offer a multi-domain license?

All extensions have an unlimited domain license. You can use them in all your web sites.


I'm getting this error message "Is not possible to create data structure.". What's happening?

Please, change the "Links relative to" setting in the site configuration options (Dreamweaver 8 or later).

If this setting does not solve the problem, then follow these steps:

  1. Restart Dreamweaver
  2. Be sure that you have a local web site defined in Dreamweaver
  3. Open the page where you want to insert the extension(this page must be saved previously into your web site)
  4. Try to insert the extension again


Can I pay using my credit card ?

Yes, Paypal allows you to pay directly using your credit card.

We also accept MoneyBookers (accepts credit cards when uploading funds).


Can I use these extensions with MACs ?

Yes, you can. These extensions are tested in all actual browsers and used from Dreamweaver on both platforms, PC and MAC.


I have downloaded the new program, but cannot seem to access it from the command panel.

Did you restart Dreamweaver after double clicking the MXP file? Please remember to restart Dreamweaver after double clicking the MXP file.


I'm getting this message "Please define your site first.". What I should do?

It's required to define a working site in Dreamweaver because Dreamweaver needs to know where to place the files.

Download here a PDF document with help about defining a site in Dreamweaver.



This extension works with Dreamweaver CS5?

Yes, all our extensions are compatible with the most recent Dreamweaver versions, including Dreamweaver MX, Dreamweaver MX 2004, Dreamweaver 8, Dreamweaver CS3, Dreamweaver CS4 and Dreamweaver CS5.


When I preview my web page after I get this message in my Internet Explorer,"To help protect your security, Internet Explorer has restricted...". What is the problem?

If you are testing your page directly from your local hard disk in IE 7, this message appears:

"To help protect your security, Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer. Click here for options."

In IE 7 this message appears when you test a web page that contains a script or Flash item directly form your local hard disk. When you upload your page to an online web server that message does not appear.

The address from a web server must start with http:// or https:// . On the other hand if the address starts with C:\ or file:// then you are testing it from your local hard disk.

Just upload your web page to your web site and you will see that the error disappears.



Note about sales taxes.

No sales tax is charged when you purchase via PayPal. You can order via PayPal with a credit card even if you do not have a PayPal account. PayPal's status as a financial institution exempts PayPal orders from sales tax. CodePeople will be the retailer of record. CodePeople is based in Switzerland and does not have any US sales tax obligations.


I'm getting this error: "TypeError: THE_DOM has no properties" . There is a workaround?

Please follow these steps:
  1. Check if  you have defined a local web site at dreamweaver.
  2. Check if you have saved the page into your local web site.
  3. If you are using Dreamweaver templates, check if your templates allow an "Editable Region" in the <HEAD> section of the HTML code.
  4. Mark the "Use case-sensitive link checking" option in the site settings and recreate your site cache.
  5. After these checks, please restart your Dreamweaver and try again.
If the above actions don’t solve the problem, then probably the reason is a wrong HTML structure in the page that you are trying to use the product, in this case, please check the page’s HTML structure and if you cannot find the problem then contact our support service.


I'm getting the error "Can't update menus. Extension will not be installed". What is the solution?

That's due to a bug in the Adobe Extension Manager that sometimes corrupts the "Menus.xml" file. That file can be found in the following location:

Windows users: C:\Documents and Settings\[UserName]\Application Data\Macromedia\Dreamweaver [version]\Configuration\Menus\menus.xml

Mac users: HD:Users:username:Library: Application Support:Macromedia:Dreamweaver [version]:Configuration:Menus:Menus.xml

To fix this problem close your Dreamweaver and try the following:

  1. Un-install all your extensions and then re-install them one at a time. This will work in most cases.
  2. If the above doesn't work then delete the "Menus.xml" file. After this you will need to disable and enable your extensions in order to get the menu entries again.
  3. If none of the above works then there is more than one file corrupted, the solution in this case will be to completely uninstall Dreamweaver and reinstall it again.
