I am researching a project and am trying to get some direction. I may be tasked with accessing a service that has a existing C API, but I don't do C proper, only C#.
So what I am looking for are recommendations on things I can do or places I can look for support on getting at this API.
 Thanks all!

You are only as good as your last project.

PInvoke.net will list the functions for Windows API's. For third-party libraries, you'll have to contact the manufacturer of the library you're trying to use.

Kindly I want to know how I can use c# to do the following tasks in LAN:
- send and receive files to another PC(s) in my workgroup
- place an a signature or E-signature to the file which i sent belong to the user
- I want this file to come back to me with the user comment and signatue to be sure that he received it and read it with the comments
- when the user wants to open the sent file he has to put a password to open that file and read it so after putting that password his signature will automatically placed in the document
- the attachments such as Word documents or exel.
thanks for interst
with best regards

how about this one.. this one might be difficult....
Private Function Decrypt_Key(ByVal bProductKey() As Byte) As String
Dim ilByte As Long
Dim ilKeyByte As Long
Dim nCur As Integer
Dim RetKey As New System.Text.StringBuilder
Dim bKeyChars() As Char = {"B", "C", "D", "F", "G", "H", "J", "K", "M", "P", "Q", "R", "T", "V", "W", "X", "Y", "2", "3", "4", "6", "7", "8", "9"}
For ilByte = 24 To 0 Step -1
nCur = 0
For ilKeyByte = 14 To 0 Step -1
nCur = nCur * 256 Xor bProductKey(ilKeyByte)
bProductKey(ilKeyByte) = Int(nCur / 24)
nCur = nCur Mod 24
Next ilKeyByte
RetKey.Insert(0, bKeyChars(nCur))
If ilByte Mod 5 = 0 AndAlso ilByte <> 0 Then RetKey.Insert(0, "-")
Next ilByte
Return RetKey.ToString
End Function

Let me show you my secret weapon: Lutz Reflector[^]. Point it to a dll or exe built in Visual Basic.NET, and it can show you the corresponding code in C#. It's a great tool and will help you with your conversion process.

It says C to VB... does it have a reverse convertion?

If it says "C to VB" it has to be a typo. Reflector shows compiled code as IL, C#, VB , Delphi, MC++ or Chrome. There is no conversion from one language to another, and there is no C code.

i think you have sent the wrong converter.. its really a c# to vb converter...
do you have a yahoo messenger?

It isn't a converter; it is a decompiler that can decompile any .NET code into C#, VB.NET, IL, and a few others. Just load up your dll that you want converted to C#, then view the disassembled code in C#.

Iam trying to overload all operators using linked lists . I need some help regarding how to
go with it and what could tbe code be like.
Will really appreciate help in this regard . Looking forward to a positive response .

Overload all operators using linked lists? Operators on what class?
For your info, the LinkedList class[^] is built into .NET 2.0
|
|
|
|
|
I really appreciate the help but iam trying to use C++ way of linked list creation in C#
without using C# linked list class . Its my assignment. I really need help regardng that .
Like
in C++ Ptr->node
here iam using Node.Prev.Next; ecetera i really need help in this . Will appreciate any input.
|
|
|
|

Instead of the C++ pointer to the next node, just declare a node reference to the next node in C#:
class LinkedListNode
{
LinkedListNode next;
...
}

Hi,
Is there any who know how i can check it a user have pit an parameter behind the application name?
ie. myapp.exe parameter
I want to load a text file into a text field, and would like to know if it was possible to find out if the file could be loaded with a parameter like myapp.exe "C:\mytext.text" if im not not wrong this is also the way file extentions are loaded when you register an extention to your application.

Use the property Environment.CommandLine to see the full commandline (including the program itself).
Or use the method Environment.GetCommandLineArgs()
string cmd = Environment.CommandLine;<br />
string[] cmds = Environment.GetCommandLineArgs();<br />
You can check for if (cmds.Length == 2)
cmds[0] will be the path of your app, and cmds[1] (if it exists) will be the first parameter after it
