What is the best way to disable copy/cut/paste in word/ppt/excel and outlook

I trapped the ctrl C, ctrl V ctrl X but the context menu and ribbon menu I cant figure out. I need to disable if the user has no permission or capture the event and verify.

thanks for you help,

Hello Rob,

You use a Ribbon Command component to intercept or disable an action. This requires that you specify the IdMso of the control to intercept (or disable); see sections Intercepting built-in Ribbon controls and Disabling built-in Ribbon controls at https://www.add-in-express.com/docs/net-ribbon-components.php#intercepting-ribbon-controls. But still there are problems that you need to bypass. Please have a look at

The information on the pages above also applies to Excel 2016.

Hi Andrei,

I have run into a little gotcha in the implementation. When the document is in Protected mode, the Ribbon Command setting seems to have no effect. I want to also turn off Copy/Cut but seems in Protected mode, I cannot. It is always there where a document not in protected mode works properly.

thanks,

Rob

Hello Rob,

I seem to have the same result. I'll try to get more information and let you know about my results tomorrow.

Hello Rob,

I found a solution a minute ago: 

private void adxRibbonButton2_OnClick(object sender, IRibbonControl control, bool pressed) {
    Excel.ProtectedViewWindow pvw = ExcelApp.ActiveProtectedViewWindow;
    Excel.Workbook parentWorkbook  = pvw.Workbook;
    Excel.Application app = parentWorkbook.Application;
    Office.CommandBars cBars = app.CommandBars;
    Office.CommandBar contextMenuBar = cBars["Cell"];
    if (contextMenuBar != null) {
        Office.CommandBarControl ctrl = contextMenuBar.FindControl(Type.Missing, 19);
        if (ctrl != null) {
            ctrl.Enabled = false;
            Marshal.ReleaseComObject(ctrl); ctrl = null;
        }
        Marshal.ReleaseComObject(contextMenuBar); contextMenuBar = null;
    }
    Marshal.ReleaseComObject(cBars); cBars = null;
    Marshal.ReleaseComObject(app); app = null;
    Marshal.ReleaseComObject(parentWorkbook); parentWorkbook = null;
    Marshal.ReleaseComObject(pvw); pvw = null;
}

Wow, I never would have figured that out. I will try it out.

Will this method work for Word and PPT too?


Also, side question, I am sure that we are not ReleasingObjects properly. Do you provide and consulting services to review code and ensure we are releasing properly so we dont have glitchy issues?

thanks,

Rob

I can't make a similar approach work with PowerPoint. I'll spend some more time on this issue and let you know about my result.

I know an only straightforward way I: you upgrade to Premium and we perform the code review as part of services the Premium subscription provides.
