IndexOf returns -1 if it's not there. Or a RegEx if you need case insensitive checking.

One way is to use the IndexOf function

I am trying to write an application that allows user login by windows authentication (includes domain and username).
For example:
Username: MYDOMAIN\MyUser
Domain:MYDOMAIN
If this username is valid, application will check for user's role, if user's role is BUILTIN\Users then this user can do their works.
But it's so difficult, can you help me?

Im trying to call a function in a class written in managed c++, from c#. The compiler interpret the types WCHAR*, BSTR and wchar_t* in managed c++ to a ushort* in c#.
This is the C# code calling the method _logonUserWithSSPI in the managed c++ code:
pExistingTokenHandle = oSSPIHelper._logonUserWithSSPI(NTLM", TOKEN_QUERY, "DOMAIN", "test", "smurf");
This is the managed c++ code (.h):
HANDLE _logonUserWithSSPI(WCHAR* pszSSP, DWORD grfDesiredAccessToToken, BSTR pszAuthority, wchar_t* szPrincipal, wchar_t* pszPassword);
How could I call this _logonUserWithSSPI method and pass the strings to it (convert a string to ushort*)?

hi,
Im developing a music centre project for college and i was just wondering could someone clear this up for me before i delve into it further.
Is it possible to rip straight from a CD to .mp3 or .ogg using C#? These are the only two format options i am allowed to use.
I have done a lot of searching and i am surprised that i couldnt find any decent information on it. I have found lots of shareware applications that do so i have to assume that it can be done, its just that no one wants to tell anyone how they didit!
At the minute im thinking off just ripping them as .wav's and then automatically converting them to .mp3 and then deleting the original .wav.
Yes this does sound crap and would take a lot of time in the application, AND i would get an awful grade for it but at the minute its all i can think off!
Any help appreciated!

Find the specification for a music cd, and then a mp3. Then with your C# skills do the conversion from the cd audio to mp3 format.

I have a stupid question:
May I include a file of any type into my project for further using?
For example, I include a text file into my project (Readme.txt), then I can read this file internally from my project by my form
|
|

|

If you set it to be an embedded resource, it's included in your assembly.
You can then, for example, use
Assembly asm = Assembly.GetExecutingAssembly();
Stream str = asm.GetManifestResourceStream("MyNamespace.Readme.txt");to get a Stream that you can read the embedded resource with.
One important fact is that you have to give the complete name of the embedded resource (including your assembly's namespace) or else it cannot be found and you'll receive null from GetManifestResourceStream().

Hi
I don't know if it's possible to include any File to a project. But I dont't think so.
But if you want to read a text file you can use the StreamReader Class.
Example:
using System.IO;
string read ="";
StreamReader sr = new StreamReader("c:\\readme.txt");
sr.ReadLine();//or any method you need
read = sr.ReadLine().ToString();
sr.Close();

no, I mean this file is included in my project, not in hard ive

Hi,
You can change the column title using ColumnName property of DataColumn.
ds.Tables[0].Columns[0].ColumnName = "Employee Id";
ds.Tables[0].Columns[1].ColumnName = " Employee First Name";
Change the column names before associating the data set with the data grid.
Hope this will help you.

I think you need something like OpenFileDialog.
Try this:
OpenFileDialog openfile = new OpenFileDialog();

My application re-configures the network settings (IP, Subnet Mask, Gateway, DNS..) and after that I want to disable and then enable the Local area connection (not the network card), so the connection is refreshed with the new settings without having to restart the computer. Does anybody have any idea on how to do it in C#? Thanks for your time.
