Hi eo_support
I'm using eo webbrowser for windows form for my project which has multiple tabs. It concludes about 10 tabs. Each tab has a webcontrol to show website's content. However, when I check Windows Task Manage, I see many rundll32.exe running. which occupies my memory. Please explain this situation for me.
Thank you!

Hi,
This is normal. EO.WebBrowser is based on Chrome's source code and has the same multi-process architecture as Google Chrome. If you use Google Chrome to open many tabs you will see a lot of Chrome.exe process through Task Manager. We use rundll32.exe instead of Chrome.exe.
Thanks!

With chrome, I can open alot of tab, but with Eo browser, I can not, because the memory is full very quickly. Is there any way for me to solve this problem?
Thanks for support!

Hi,
The high memory usage has to do with the fact that we have everything packed in a single DLL EO.WebBrowser.dll. We do have a multi-DLL build that will reduce the memory consumption. We will post it on our download page very soon so that you can give it a try. We will reply here again as soon as the new build is posted.
Thanks!

Hi eo_support!
You should put this on NuGet package, so people can easily integrate it into their project, will be very handy!
Thanks!

Hi,
i did as instructed, but the asp.net MVC project does not work. I get following error "The DLL must be in the same directory as EO.WebBroser.dll". All required dll are in the same bin directory, but it is not working.
Thanks,
Matjaž

Hi Matjaz,
You probably don't want to use multi-DLL build with an ASP.NET MVC project. In theory it will work --- but ASP.NET copies all DLLs into a temp directory from you bin directory. So you will need to find out that temp directory and copy all the files into that temp directory (ASP.NET won't copy those automatically for you because they are not .NET dll and your application does not reference them directly). This is why our default distribution uses single DLL distribution. It saves you from this kind of trouble and is much easier to use.
Thanks!

Hi,
for all who wont to use mutiple dll in web project. It works great and memory consumption is half a consumption of single dll.
1. In web.config add <hostingEnvironment shadowCopyBinAssemblies="false" /> in <system.web> to prevent copying dll to temp folder
2. Copy all WebBrowser dlls in root of project
3. Reference EO.WebBrowser.dll to the project
4. After rebuild, copy all WebBrowser dlls to bin folder
That's all
Matjaž

Yes. It can be normal. Usually there are at least three processes: at least one for rendering (running HTML parsing, layout, rendering and JavaScript, there can be multiple rendering process), one for GPU, and one for everything else (network, cookies, and coordinates other processes). If your page uses plug-in, then another process will be created for the plug-ins. All these are designed to isolate different component into different process so that if one run into problem, all other portion will still be functional. For example, if a buggy plug-in is loaded and crashes, then only the plug-in process crashes and HTML parsing and layout will still be functional. So in this case all other part of the web page will still be functional, and only the plug-in is not functional.

hi eo,
i tried this multi-process following the instructions. Our VS solution when built outputs all binaries (DLL/EXE) to R:\bin folder so all the DLLs are copied to R:\bin folder. but when i ran the app, it complains EO.WebBrowser.Native.dll is missing.
Note, my app is not ASP.net app.
regards
philip

Hi Philip,
What is the exact error message you got? Please also check if you use shadow copy for your application. In the latest build, if your application uses shadow copy (such as an ASP.NET app), we will search the shadow copy source directory for the DLLs (the bin directory for an ASP.NET app), not the actually DLL loading location (the temp folder that contains the shadow copies of the original DLLs for ASP.NET app).
Thanks!
