// class: CManageActCtx

//
|
|
// Purpose: To deactivate UI theme context (if set) and restore
|
|
// the context automatically.
|
|
//
|
|
// Usage: 1. Call Activate to set the activation context to V5
|
|
// common controls. This is needed before calling into snapins
|
|
// so that snapin created windows are not themed accidentally.
|
|
//
|
|
// The snapin can theme its windows by calling appropriate
|
|
// fusion apis while calling create-window.
|
|
//
|
|
// 2. Call Deactivate to restore the activation context.
|
|
// This is needed after calling into snapins, so that
|
|
// if we called from themed context then it is restored.
|
|
//
|
|
// Explanation:
|
|
// When MMC calls into the snapin if the last winproc which
|
|
// received a window message is themed and will result in a
|
|
// call to snapin then we will call the snapin in themed
|
|
// context. If snapin creates & displays any UI then it will
|
|
// be themed. This function is to de-activate the theming
|
|
// before calling the snapin.
