HtmlBox don’t show files inside of browser any more in VWG6.4

Hi,

I have a dialog with an HtmlBox inside with the purpose of show files inside of browser.

In VWG6.3 the same code works well for most of file formats like for example pdf files, after upgrade to VWG6.4 this don’t show anymore pdf files inside.

I have tested in IE and Firefox and the behavior are the same for both bownser: when compile code in VWG6.3 shows pdf files inside of IE or FF, but when compile the same code in VWG6.4 pdf files are not showed any more inside of the browser.

There are needed some code changes when upgrade to VWG6.4?

Thanks & Regards,

Rui

Hi Rui,

I can't remember any details at the moment that you need to do differently in 6.4 compared to what you did in 6.3. For testing, I downloaded the "sample gateway listing folders ..." codesample linked from our Gateway article here and tested both in 6.3 and 6.4 and I am unable to see any different behaviour.

I even added a new form with a button that would open the original form in a dialog, and it still shows the PDF inside my IE9.

I would advice a full clear of caching on your 6.4 project and if that does not work for your, please create the most minimal reproducing sample application, clean it, zip it and email it to the support email address (see my signature) along with the full Http reference to this thread. Please also post here when you have sent the email.

I think it's a good idea that you include the PDF document(s) that you have problems with in case your problem has any relation to the contents of the PDF, although that should in general not be the case.

Hi Palli,

Thanks for the reply.

It is solved now. The problem was not related with VWG6.4.

We have changed our function to get mime string directly from registry, but I don’t know why .pdf mime definition string does not exist in my Windows7 computer.

It is solved now by correcting the function to get mime.

Anyway I will post here the function, maybe could be useful to others:

public static string m_GetMimeFromFile(string file

{

string mime = "application/octetstream";

string ext = System.IO.Path.GetExtension(file).ToLower();

Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);

if (rk != null && rk.GetValue("Content Type") != null)

mime = rk.GetValue("Content Type").ToString();

return mime;

}

Thanks & Regards,
