You cannot resize or reposition a WebBrowser control window in Windows Internet Explorer 7

INTRODUCTION

You cannot resize or reposition the WebBrowser control window in Windows Internet Explorer 7 when an application hosts a WebBrowser control. Additionally, the application may not receive the WM_WINDOWPOSCHANGING notification messages as expected. This behavior is a security enhancement in Internet Explorer 7.

MORE INFORMATION

This behavior occurs if the script on the WebBrowser control contains calls to any of the following methods:
  • window.moveTo
  • window.moveBy
  • window.resizeTo
  • window.resizeBy
A security change in Internet Explorer 7 prevents the WebBrowser control from spoofing the host application. Therefore, these methods do not work for applications that host the WebBrowser control.

APPLIES TO
  • Windows Internet Explorer 7 for Windows XP
  • Windows Internet Explorer 7 in Windows Vista

Community Feedback System

Very often, it takes hours to solve a problem. Very often, you've looked high and low, and have tried a lot of solutions. When you finally found it, chances are, it was because someone else helped you. Here's your chance to give back. Use our community feedback tool to let others know what worked for you and what didn't.

Please also understand that the community feedback system is not warranted to be correct, it's simply a system that we've built to let people try and help each other. If something in a feedback response doesn't make sense to you, or you're not comfortable making changes that the feedback talks about (like registry edits), please consult a professional.

Thank you for using kbAlertz.com Feedback System.
