File browsing dialog has been blocked

Reply Quote

I am getting the following message when I click on the "Upload" button. What does it mean?

I had Flash 10.3.181.28 and upgraded to 10.3.181.34 just to be safe but I still get the same problem.

I cannot reproduce on your sample page. I'm assuming it's because it uses Silverlight. Do you have a sample page which uses Flash?

I'm using IE 9.

frJericho,

You can disable the Silverlight in your browser then try again.

1. If Ajax Uploader detects SilverLight is installed on your PC, It will use the SilverLight solution.

2. If Ajax Uploader detects Flash is installed on your PC, It will use the Flash solution.

3. If Ajax Uploader detects Iframe is supported on your Browser, It will use the Iframe solution.

4. For downlevel browsers, Ajax Uploader will render as default ASP.NET upload control.

In IE, go to tools (Alt+X) , choose "Manage Add-ons".

I think I can answer my own question: why does it uses Flash in my sample page and Silverlight in yours?

I have the following line of code which seems to force Flash:

htmlcontent.UseStandardDialog = true;

When I switch this value to "false" my browser starts using Silverlight.

Is that right? Is CuteEditor forcing Flash when the standard dialogs are used?

My original question remains: why am I getting an error message about the diaolg being blocked when using Flash?

Hello I am one of FrJerichos customers affected by this issue. If I click on the 'Upload' button nothing happens. When I close the window after that IE 9 locks up on me and I have to force it to close. If I tab to the 'Upload' button and press enter, I see the pop up that FrJericho posted originally.

I'm using IE 9, Windows 7 64 bit SP1. Let me know if I can provide any more information to help resolve the issue.

Continuing my investigation, I am attempting to force the uploader in InsertImage.aspx to use Silverlight by adding UploadType="Silverlight" like so:

<ce:uploader id="InputFile" UploadType="Silverlight" runat="server"></ce:uploader>

but I get the following error message:

this is clearly wrong because I already have the latest version of Silverlight installed on my machine.

Here a summary of what I have discovered so far:

When the editor is configured to use standard dialogs, the uploader ignores Silverlight and uses Flash. Why?
When the uploader uses Flash, some of my users get the "File browsing dialog has been blocked" error message. Why?
When I attempt to force the uploader to use Silverlight I get a message that I should get the latest version of Silverlight despite the fact that I already have the latest Silverlight on my machine (screenshot above). Why?
Someone else observed similar problems when using standard dialogs: http://cutesoft.net/forums/thread/49725.aspx

I was asked to attempt to perform the upload at http://richtextbox.com/test/UseStandardDialog.aspx and I experienced the same errors however this image uploader works flawlessly...

The above image occurs when I tab to the upload button and press enter.

The above image occurs when I try to close the window after I attempt to upload and it fails.

In the standard dialog example, Cute Editor uses showmodaldialog function in IE.

We think silverlight has some problems in showmodaldialog. This cause silverlight is not loaded correctly in showmodaldialog. So the Flash mode is used.

Since silverlight can not be loaded correctly, so UploadType="Silverlight" will trigger an error.

"File browsing dialog has been blocked" For this error, do you know which browser they are using and what the flash version is?

In case you are wondering why I absolutly have to use standard dialogs: I am displaying the CuteEditor in an IFrame which is causing several problems as descripbed here: http://cutesoft.net/forums/thread/45310.aspx As Adam suggests in that thread, the standard dialogs resolve the problems. This demo page very closely mimics my situation: http://richtextbox.com/test/iframe.aspx and I can reproduce the problem in that demo page as well.

I feel like I'm trapped: I have to use the standard dialogs in order to overcome the problems related to displaying the editor in an iframe but standard dialogs cause Flash to be used and the file browse dialog is disallowed in that situation.
