title: How to read/write excel checkbox status in c++
body: <p>I am working on an issue that requires me to read/write status of a checkbox in a given cell in Excel.</p>
  
  <p>I know that you can access activeX controls can be accessed using COM/OLE. However, I have not been able to find any solution to this problem. In fact, I am not even sure if you can access checkbox using row-column. I studied the properties of activeX checkbox. Found top and left properties, but not row-column</p>
  
  <p>I want to ask if:
  1. Is there any direct way to do this.
  2. If not, any indirect way, say getting the top/left column somehow and then getting row/column positions and comparing the two.
  3. Is there any way to do the same with form controls?</p>
