Print Preview Crashes

[win568neu]

Hi Salvador

The "normal" Download of Files works. But if you are in the Pdf Previewer and Press the Download Button, than it comes to an Exception and the Application closes. In the Callstack, i see the Function libcef.RelaunchChromeBrowserWithNewCommandLineIfNeeded and GetHandleverifier which are constantly called. I send you the Stacktrace:

I tried to reproduce this issue with cefclient, MiniBrowser and BriskBard but I couldn't make them crash.

Please, check that the CEF binaries used by the application were copied from the "Release" and "Resources" directories. Sometimes using the binaries from the "Debug" directory cause unexpected issues.

Provide a step by step guide to reproduce this issue in my computer with one of the demos.

Hi Salvador

I already had problems and therefore only use the CEF binaries from the specified directories.
Our application is more like the TabbedBrowser. I will therefore try to reproduce the problem with your demo application.

I'm currently still working on our IDE experts, but hope to get it done this week.

Hi Salvador

Good News. I found the issue. I used the wrong handle for a window message. Therefore an exception occurred during the download. Now the download also works

Hi Salvador

When I view a PDF file in the CEF PDF plugin and press the download button, a popup appears that contains the file name and 2 buttons for opening the folder and viewing the file respectively.
How can you deactivate this? I have already set Downloadbubble to STATE_DISABLED but unfortunately it still shows that

[salvadordf]

I just uploaded a fix for this issue to GitHub.
Please, download CEF4Delphi again.

Hi Salvador

Thank you very much. Now it works.

You told me to report problems to you. If the download bubble is displayed and you click on the "Open button", then it crashes in libcef.dll.

It's irrelevant to me at the moment because we display the ad differently.

Thanks for reporting this issue!

I still can't reproduce that crash using cefclient, MiniBrowser or BriskBard. I'll keep doing more tests.
