How to use treeview,multiple projects in one solution explorer and search from databases

(1) How to use treeView control to open Ms word document
(2) How to work with two or more projects in the same solution explorer and calling classes from each other
(3) How to search a databases in c#.net

First treeview is used to explore hierarchical strucutre by expanding nodes and not for starting processes like microsoft word, but if you want to start a process from your application you can do that by including

System.Diagnostics.Process.Start(file path);

Second you can do that by including a project into another, I explain, suppose that you have two projects ProjectA and ProjectB in the same solution if you want to use ProjectA classes within ProjectB you have to add in the namespaces list of the ProjectB
using ProjectA;

Third, I didn't understand excatly what do you mean by search data bases, are you meaning make SQL requests against data bases to get records or something else?
