MFC applications created by the MFC App templates will usually save and restore UI from the registry after the first run. To see your changes after rebuilding the application delete the saved registry data before you run it again.

The registry location is set in the InitIntance function. For example,

    // Standard initialization
    // If you are not using these features and wish to reduce the size
    // of your final executable, you should remove from the following
    // the specific initialization routines you do not need
    // Change the registry key under which our settings are stored
    // TODO: You should modify this string to be something appropriate
    // such as the name of your company or organization
    SetRegistryKey(_T("Local AppWizard-Generated Applications"));

This is what the data looks like under HKCU -

MFCUIRegistry

Initial toolbar -

Initial

Revised Resource -

ReorderedButtons

After deleting the MFCTBButtonOrder registry key and subkeys -

While deleting the registry information solves the annoying problem that you have seen during development you should decide if you want your deployed release version to exhibit the same behavior. In other words, do you want your application to save and restore its UI for actual users? If the answer to this question is "Yes" then you need to exclude this code from your release version.

Thanks for your warm remind! Because our app don't need to customize the toolbar now, so this solution is good for us.

The use of the registry by MFC to save and restore UI applies to more than a toolbar. I suggest that you test by commenting out the registry data delete code. Then open and close the application several times while changing window size and position with each run. This will give you a better sense of what the MFC framework is saving and restoring.

For my own development system I added an external tool to Visual Studio's tool menu. This runs the reg delete command to delete a project's saved MFC data from the HKCU key. This simplifies development for me with the added benefit of not changing code.

Wow! You gived a humanized way to delete the registry, that is better than delete regs each startup. And I also found the app saved some infos to the registry when closing, it's worth for me to learn about it more.
