No, previous applications do not have an effect on subsequent applications.

Every case is taken on its own merits to satisfy the ECO that you have reasons to return home which must outweigh reasons to overstay hence the ties which must be shown to your homeland.

Visit visas are notoriously difficult to obtain but not impossible and total discretion lies at the hands of the ECO so the stronger the application you present the better chance you may have.

Good luck on your forthcoming decision....
