Hi,

we also have the same problem with the OCX from MW6 for QR code. The PB Webbrowser crashs and that have made us a criticl product crash for 2 days because we don't have find the cause until we suddenly found how we could reproduce the behaviour. Is there a patch for this bug? The suggestion of Miguel Leeuwe didn't work for us. What could be a alternative way to generate Qr Code which is compatible with everything ;) ?

Hi Dave;

  FYI: We have had a few crashes like this reported in the Support System but only when the PB App uses certain 3rd party controls / DLLs. One example is EZTWAIN product that when enabled when using the internal Web Browser control causes the PB App to crash. In this case, Engineering is still investigating this situation.

  Does your PB App use any external DLLs or OCX's like EZTWAIN (for example). If so, does the crashing stop if you comment out the instantiation of these 3rd party products (as a quick test)?

Hi,

I solved some problems with the webbrowser control by inserting this code, which HAS to be in the application object's Open() event:

// seems to be a necessary setting for CEF webbrowser control:
int li_ret
string ls_ret
li_ret = WebBrowserGet("UserAgent", ref ls_ret)
if ls_ret = "" then
	li_ret = WebBrowserSet("UserAgent", "AppeonWebBrowser")
	if li_ret <> 1 then
		Messagebox("Information", "Error setting the UserAgent for the WebBrowser", information!)
	end if
end if
// avoid an existing Appeon bug of blowing up when using the webbrowser control on Windows Server 2012 R2:
// w_wbrowser_dummy is a tiny invisible window with nothing in it
open(w_wbrowser_dummy)
close(w_wbrowser_dummy)

// this might not be necessary for resolving your problem:
string ls_docFolder
n_filesys lnf
ls_docFolder = lnf.of_getfolderpath(CSIDL_PERSONAL)

li_ret = WebBrowserSet("DownloadPath", ls_docFolder)
if li_ret <> 1 then
	Messagebox("Information", "Error setting the DownloadPath for the WebBrowser", information!)
end if
li_ret = WebBrowserSet("allow-file-access-from-files", "true")
if li_ret <> 1 then
	Messagebox("Information", "Error setting the FileAccess for the WebBrowser", information!)
end if

I hope it solves your problem, if not I'd suggest you create a support ticket on https://www.appeon.com/standardsupport/newbug

With the old one : Microsoft Web Browser, there is no crash
