hi i am trying to read NTFS share permission. Imported

<br />
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]<br />
            protected struct SHARE_INFO_2<br />
            {<br />
                [MarshalAs(UnmanagedType.LPWStr)]<br />
                public string NetName;<br />
                public ShareType ShareType;<br />
                [MarshalAs(UnmanagedType.LPWStr)]<br />
                public string Remark;<br />
                public int Permissions;<br />
                public int MaxUsers;<br />
                public int CurrentUsers;<br />
                [MarshalAs(UnmanagedType.LPWStr)]<br />
                public string Path;<br />
                [MarshalAs(UnmanagedType.LPWStr)]<br />
                public string Password;<br />
            }<br />

According to MSDN, Permissions include ACCESS_READ, ACCESS_WRITE, ... etc but the document doesn't tell you the "Integer" value of these constants. Where can I find the C++ header file where these constants are defined? I need them so I can convert integer value "Permissions" into human readable message.[^].

Thank you!

I found this SHARE_INFO_503 structure (Windows)[^] which uses the same value names, but in this documentation the actual values are mentioned.

At the bottom of that MSDN document, you'll see it says "Header: Lmshare.h (include Lm.h)".

Searching the header files listed in Lm.h for one of the values will lead you to LMaccess.h. The values start on line 1250 of that file:

C++

#define ACCESS_NONE         0
#define ACCESS_ALL          ( ACCESS_READ | \
                                ACCESS_WRITE | \
                                ACCESS_CREATE | \
                                ACCESS_EXEC | \
                                ACCESS_DELETE | \
                                ACCESS_ATRIB | \
                                ACCESS_PERM \
                            )

#define ACCESS_READ         0x01
#define ACCESS_WRITE        0x02
#define ACCESS_CREATE       0x04
#define ACCESS_EXEC         0x08
#define ACCESS_DELETE       0x10
#define ACCESS_ATRIB        0x20
#define ACCESS_PERM         0x40

I am to search these URL from web. It's like google. google serach key world from web pages i want the same but as we know that google work on the indexing. I want to return only the website url that is similiar to entered word

Re: return list of url if i enter specific keyword

Then you first need to create a database of all URLs that exist in the world; that will be quite a big list.

You could only do this by building up a list of all visitable URL's and then you could query that.

When you search via Google, they aren't going off and hunting for matches on the web at that point. They search their indexed versions, which they have previously crawled. You need to take a similar approach in order to satisfy your requirement.

Why don't you use google for that. Try the following search:

allinurl: codeproject answers

This will give you all urls that contains "codeproject" as well as "answers" as keywords.

Try it out!

C# timeout

I am running a C# 2010 windows application that calls a C# 2008 console application to make various calls to a web service. I am getting the following timeout error. I am wondering what part of the application I should look at to determine what is causing the timeout? Both applications are compiled in debug mode.

I am wondering if you can tell in the application what timeout parameter(s) need to be changed? What coding changes would I make to prevent the timeout errors from occuring?

Here is the error message:

 Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.

As your stack trace mentions SQLClient in almost every line I would suspect it is your database query that is timing out, that will live in your WCF. You can change both the the connection timeout and/or the command timeout.

If it is a large application and especially if it is a system (multiple applications like you're having) you might want to consider some serious logging. The timestamps in the log can immediately tell you where the culprit is.

I suggest thinking the logging mechanism over for a while before jumping in a quick and dirty solution. Good logging saved my day in numerous times.

Hope this helps.

What you need to do FIRST is determine what is being processed (presuming some SQL.)
The SECOND you need to determine what a reasonable time for that process to take - especially from the business side.

As an example it unreasonable to expect a user to wait for an hour for a web site to finish processing a request (where the web app is blocked until it is done.)

To "fix" a problem like this depends on the specifics of the problem but some or all of the following might be necessary but this is not a complete list.
- Tune the database/schema
- Adjust the SQL operation parameters or SQL itself.
- Rearch/design the interface to preclude such operations.
- Rearch/design the interface to create a batch processing system where a request is posted, some other process processes each request, and some time later a result is created, then the caller at some later time, may submit another (different) request to retrieve the result.

Hi,

It is never easy!! We have a response file which has two types of decisions, ACCEPT and DECLINE with in the comma separated name/value pair. I am inserting this information in to the database and want only the decision ACCEPT. In cases in line contains DECLINE, I want to skip this current line and go to the next line.

I am using the StreamREader to read the file.

Thanks!

Very simplistic, but something along the lines of:

if (line.Contains("ACCEPT"))
    // Do something.
else
    // Do something else

Just some pseudo code but that might set you off in the right direction. Might have been useful to see some code.

try something like this.

using (StreamReader sr = new StreamReader(path))
{
   while (sr.Peek() > -1)
   {
     string line = sr.ReadLine();
     //extract the line contents
     if( line.Contains("Accept")) // you can replace the condition with your choice
     {
        //Do Insert to database
     }
   }
}

Thanks!

Line.Contains("ACCEPT") worked perfect!!

Wanted to find out, since you are already doing a PEEK, why are you still checking to see of the line is NULL?
