Hi Guys and Gals.
I have a simple question, but for the life of me cant find an answer out there.
I have a string that will contain an Expression: string x = "(2+3)+((7*2)-5)";
I need x to execute now as an expression in order to get the result of the expression.
Eg. decimal y = (2+3)+((7*2)-5); [This is the value from the text string x]
Result in y = 14
Your help will be greatly appreciated or your guidance to a possible workable solution.
Kind Regards,
Elizma

Thanx for your help! I tried searching for it before I asked the question, but I guess my search criteria was wrong since the I put in "Convert String To Expression".
I found something that works.
E.g.
string x = "(2+3)+((7*2)-5)";
DataTable dt = new DataTable();
object sumObject;
sumObject = dt.Compute(x, "");

use Reverse Polish Notation
Expression can be analyzed
Often used to calculate the string

That sounds like requirements from a homework assignment; not a real-world requirement.
Reading and writing directly from an existing file will only work if the resultant file doesn't increase in size.

Hi,
I'm working on an application which reads a pdf document. As we all know we have hand tool in most of the pdf reader, which is used to scroll the document. My issue is when I use the hand tool to scroll the mouse, the speed of the movement of the mouse and the speed of the scrolling of the document is not synchronized. Not matter how fast or slow I move the mouse, speed of scrolling of the document remains same.
I need help in developing the logic for this.
Thank you,
Pavan Navali.

You mean from CP?
There are lots and lots of articles here. Search what you want. Read them and download source if present.

It depends on the website. If you're talking about CodeProject, then there's usually a link at the top of each edited article.

Ok so I am having a big problem with this. I had a problem with getting a remote servers serices to stop with WMI and ended up using a ServiceController instead (worked great).
I created a application that got all computer objects from AD. When you click on those computer objects it gets information such as services (and their state), installed applications, disk drives, and other information such a manufacturer, model, etc.. All of this works perfect!
The problem is I can't uninstall software. If I use the same credentials as I do getting the information I get an 'Access Denied' Error
ConnectionOptions conn = new ConnectionOptions();
conn.Impersonation = ImpersonationLevel.Impersonate;
conn.EnablePrivileges = true;
But if I do this I no longer get the access denied error and get the RPC server is unavailable:
ConnectionOptions conn = new ConnectionOptions();
conn.Authentication = AuthenticationLevel.Default;
conn.Impersonation = ImpersonationLevel.Impersonate;
conn.Username = "DOMAIN\USERNAME";
conn.Password = "PASSWORD";
conn.Authority = null;
conn.EnablePrivileges = true;
So how come I no longer get the access denied error and get something abouit the RPC server is not avaiable? How is this since the RPC service IS available since I just got tons of information from it!
Also if you are suggesting I try this instead of DOMAIN\USERNAME:
conn.Authority = "ntlmdomain:DOMAIN";
it doesn't work. When I do it that way it still gives me a access denied error.
I noticed someone else seemed to have this issue:
http://www.codeproject.com/Messages/2903205/WMI.aspx[^] but it was never resolved it looks like.
I have googled the crap out of this error message and tried everything that I found suggested (changing the AuthenticationLevel, changing the ImpersonationLevel) and it didn't work for me
