Hello everyone,
I am developing an application which contains a tree structure. The tree structure reflects the management structure of a big company -- child node represents the employees managed by direct manager (parent node), one parent node may have multiple (various) number of child nodes (employees he/she managed in his/her department).
I need to find all the employees a manager managed in the tree structure, the direct child node, the child node's child node, ... and so on (for example, if he is a senior manager, there are multiple levels of child nodes).
Currently, I am using brute force tree traverse approach to print all (direct and indirect) child nodes -- layer by layer. The tree is very large. I am wondering whether there are any good ideas about how to improve the search performance?
thanks in advance,
George

Use ShellExecute or ShellExecuteEx

"Never Judge a book by its cover.. So you can only judge those u love"

::ShellExecute(NULL, "open", "iexplore.exe", "1.htm", NULL, NULL, SW_SHOWNORMAL);

Why don't you do a debug session and single-step the code?
Then you will know exactly what's going on, and find out where the problem is.

hi

Then please tell us this:
What is your specific problem? What's not working?
What statement dosen't work?
You can't expect anyone to copy your code, clone your database e.t.c. and then come up with a solution.
