Memory leaks

This is a pre-sale question. I do not have your software yet.

I developed an IE add-on that uses .Net generated interop wrappers for SHDocVw and mshtml. There are some unmanaged memory leaks in interop dlls that affect IE after a few hundred pages. The IE starts to cancel all navigation requests sent from the address bar.

Does the Add-in-express library has any advantages over WebBrowserClass wrapper when it comes to memory management? Do you have any tools to profile unmanaged code memory leaks?

Thank you

Hi Vladimir,

It would be a bit incorrect to compare the WebBrowser control and Add-in Express for IE.
Add-in Express is a tool for developing IE add-ons/extensions. While the WebBrowser control is usually used in standalong applications to host the web browser.
We have never been reported about memory leaks in our product. Anyway, when any issues emerge, we fix them as soon as we can.

Thank you, Sergey.

I am not referring to WebBrowser control which is a part of .Net library. I want to compare your tool with Pavel Zolnikov BandObject and SHDocVw interfaces which I use to get access to Internet Explorer events and DOM model. While BandObject works fine, the interoperability wrapper generated by VS for SHDocVw.dll has memory leaks. That is why I asked if use this wrapper.

Hi Vladimir.

How can I reproduce the issue with the interop assembly? Probably you have any sample code.
