Q. Internet Explorer 7 supports a Windowless SELECT control as well as the Windowed SELECT control?

The new Windowless SELECT control in Internet Explorer 7 was designed to replace the Windowed SELECT control, but some compatibility issues with Microsoft Office caused Microsoft to support the Windowed SELECT control for programs that you specify.

If you open a CMD.EXE and type reg query "HKLMSOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_USE_WINDOWEDSELECTCONTROL", you receive:

! REG.EXE VERSION 3.0HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_USE_WINDOWEDSELECTCONTROL    excel.exe   REG_DWORD       0x1    infopath.exe        REG_DWORD       0x1    powerpnt.exe        REG_DWORD       0x1    winword.exe REG_DWORD       0x1

The above programs default to using the Windowed SELECT control.

When MSHTML is loaded, the default behavior is to use Windowless SELECT control when an application has no Value Name in at the

"HKLMSOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_USE_WINDOWEDSELECTCONTROL" key, or if it's data value is 0.

If your wanted to add YourApplication.exe to the list of applications that use the Windowed SELECT control, use the following command:

REG ADD "HKLMSOFTWAREMicrosoftInternet ExplorerMainFeatureControlFEATURE_USE_WINDOWEDSELECTCONTROL" /V YourApplication.exe /T REG_DWORD /F /D 1
