If i persue my bachelor's in BCA or B.com from india but from a open University like ignou (Indra Gandhi open University), will i get admission in any foreign country?

Yes, ofcourse. Why would you think otherwise?
Universities abroad mention that your bachelor’s degree needs to be from a recognized university. As far as I know, IGNOU is a very recognized and well reputed university. So I don’t thing you have anything to worry in this matter.

Apart from this, the parameters that actually play a key role in your selection are:
1. Bachelor’s GPA

2. Entrance Test Score (GMAT/GRE)

3. Language Test Score (IELTS/TOEFL/PTE etc)

4. Work Experience

5. Extracurricullars

The score requirement varies across courses, schools and countries. Thus, you need to check for your preferred course and apply accordingly.
