In my program, I need Memory Scanner. I've used this one: http://www.codeproject.com/Articles/716227/Csharp-How-to-Scan-a-Process-Memory
I've created a new C# file named MemoryScanner.cs and copied the code there.
How to run it from here:
private void startButton_Click(object sender, EventArgs e)
{
//here I would like to invoke the MemoryScanner
}
Thanks in advance for every help. :)
Apparently (from looking at the code of the link your provided), the entry point of the program is the static method Main in class Program in namespace MemoryScanner. Call this method to start the code.
Some points should be noted:
The implementation is left as an exercise. (If you really don't know how to call a static method in C#, please start with a good, basic C# tutorial.)
Currently, the code analyzes a process called notepad, outputs the result to dump.txt and waits for Console entry before returning. If you want to use that as part of your program, you will need to change these things. (Hint: Remove the Console parts and pass the values, which are currently hard-coded, as method parameters.)
In a nutshell: If you want to use the code, you won't get around reading and (at least partly) understanding it.
You need to add a using statement at the top of your page.
using MemoryScanner;

I am creating a program which shows a form with a text field and activate button, there are certain code which are entered by the user in the text field and on clicking activate button it does the work based on the code inputted by user.
I have successfully created a form and in the activate button click event it calls the method of another class (named Output) like below
Output o = new Output();//Created object for output class
o.effect(s.Text);//here effect() is function of Output and s is textfield
And in Output class's effect() function
void effect(String str)
{
switch(str)
{
case "code1": Console.Write("you enter code1"); //all the things to be done if code1 input
break;
...
...
default: ...;
break;
}
}
The above classes were successfully compiled and run properly. But now I want to make a dll support for this program so that whenever I have to add more code I can just easily create a new dll (Say, Outputversion2.dll) in which there are code like above Output class which can be entered in main program form.
Something like a code extension...
I don't want to mistakenly damage the main program by editing every time to add more codes that's why I thought of it.
Hope you understand what I want to do.
I am just beginner with c# , just learned a month ago.
Sorry for any Grammar error, my English is also not so good.
Thank U.
I'm not sure what you are trying to do here. If you're hoping to be able to dynamically add new DLLs, each with a set of handlers (i.e. cases), then you should probably use the Managed Extensibility Framework. Otherwise, if what you are trying to do is to simply have all handlers in one separate DLL that can be replaced at any time, you should place the Output class in a Class Library, which will compile into a DLL; you can then swap out versions of this DLL without worrying about changing the main program, so long as you don't change the interface (the classes and their functions' return types and parameters; you can change the code inside the function as much as you want).
Also, if your worried about destabilizing the main program, I would recommend keeping backups of the source code, and not releasing new versions until you have fully tested them multiple times.
I hope this helps.
I'm new in C# programming, can someone tell me on how to change display syntax in C#?
What I would like to output is that instead of:
Console.WriteLine("Hello");//output is "Hello"
I will change Console.WriteLine to other words, but still its use is for displaying output.
PrintIt("Hello");//output is "Hello"
I wanna use it in textbox and display it in the label. How to do this?
I'm hoping that you can help me. Thank you
You can define new procedure PrintIt() for that
public void PrintIt(string message){
Console.WriteLine(message);
}
public static void Main(String []args){
PrintIt("Hello");
}
Your Can Create a method like the Guy before me showed you or even u can create a Snippet and then use it every time you start a new project without the need to write the method again.
A code snippet is a block of reusable code that you can insert where you need it in your code. Snippets can be simple or more complex—for example, blocks such as try-finally and if-else are commonly used, but you could also use snippets to insert entire classes or methods.
For instance if you are familiar with the shortcut ctor you will know that tapping twice after you wrote that it will generate a constructor for you
Okay, I'm writing a language compiler in C# that converts my language into MSIL and then calls the MSIL compiler. But that's beside the point. I created some code to show you want I'm going to be working with:
module myApplication
[EntryPoint]
function void start
write("Hello World!\n")
wait(5) // wait 5 seconds
ret()
endfunction
endModule
Okay, I'm trying to scan through that code and find where "[EntryPoint]" is and then find all the "function void start" after it. So I can find the function type ("void") and name ("start"). The [EntryPoint] tag will always be above the function that will be defined as the applications entry point. And I will have to make it trim the whitespace and stuff. This is also scanning through using '\n' so the function MUST be under the tag.
And I also have another question, how would I make it separate the code inside the function from "function void start" and "endfunction"?
There is a lot more to writing a compiler than simple string manipulation - for example what if your source instead looked like this:
module myApplication
string myString = "[EntryPoint]
function void start
write("Hello World!\n")
wait(5) // wait 5 seconds
ret()
endfunction"
endModule
I.e. your source defines a string containing the source for a program - you can't just look through for something that looks like an entry point, you need to actually parse your source.

The GNU Objective-C runtime provides a way that allows you to execute code before the execution of the program enters the main function. The code is executed on a per-class and a per-category basis, through a special class method +load.
Update: the answers I read below are not satisfactory. There's nothing special to call a function from a main program. The question is about HOOKING the SYSTEM that is the SYSTEM calls a function without YOUR PROGRAM even aware of it at RUNTIME.
Instead of Objective C see this article on Visual C++ (thanks to stackoverflow guy who answer my previous question):
http://www.codeguru.com/cpp/misc/misc/threadsprocesses/article.php/c6945
Otherwise there was no need for Objective C Runtime to include this load method. main entry point of course exists for Objective C program and if it suffices to just call a static method WITHIN the main method there's no big deal :)
In OOP languages since main is always inside a class, there is always a way to run some code before main function is executed. In Java it's called static initialization block. A similar mechanism is also available in C#. See this link
Code example:
namespace CSharpConsoleTest
{
class Program
{
static Program()
{
Console.WriteLine("Test123");
}
static void Main(string[] args)
{
Console.WriteLine("Test111");
}
}
}
Well the point is to be able to initialize static variables inside the class since they are created before instance variables.
What your are looking for in c# are called class constructors(runs before) and class destructors(runs after)
Here is a link to a tutorial...

Sorry i am new to C#. I have a program, where there is a class CatchFS. The main function in the class , has the code
CatchFS fs = new CatchFS(args);
fs.Start();
Can someone tell me what it means. I hv heard of thread.start() but object.start() is new to me . Am i even thinking right ?
Thanks a lot, Yes it is derived from a class called FileSysetm.cs. The start does this : public void Start ()
{
Console.WriteLine("start");
Create ();
if (MultiThreaded) {
mfh_fuse_loop_mt (fusep);
}
else {
mfh_fuse_loop (fusep);
}
}
Now im trying to do a fusemount. The program starts and it hangs. there is some call that was not returned and i couldnt figure out which one. I tried using debug option of monodevelop, but no use, it runs only in my main function and I get thread started and thats it !!
I think the file FileSystem.cs is from library Mono.fuse.dll. Thanks for all your time. I hv been looking at this question for 2 whole days, and I dont seem to figureout much as to why the code wont proceed.Im expecting my azure cloud storage to be mounted in this fusemount point. My aim is after running this code I should be able to do an ls on the mountpoint to get list of contents of the cloud storage. I am also suspecting the mountpoint. Thanks a lot for providing me all your inputs.
There is no object.Start method. Start must be a method of the CatchFS class or some base class from which CatchFS derives.
If possible, consult the documentation for the library CatchFS comes from. That should hopefully explain what CatchFS.Start does.
If the documentation is sparse or nonexistent but you do have the source code, you can also simply take a look at the CatchFS.Start method yourself and try to figure out what its intended behavior is.
If there's no documentation and you have no source code, you're dealing with a black box. If you can contact the developer who wrote CatchFS, ask him/her what Start does.
One final option would be to download .NET Reflector and use that to disassemble the compiled assembly from which CatchFS is loaded. Treat this as a last resort, as code revealed by Reflector is typically less readable than the original source.
Start is a method on the CatchFS class (or one of its parent classes) - you'll have to read the documentation or source for that class to find out what it actually means.
According to the MSDN Docs for Object, there is no Start method. This must either be a method of CatchFS or one of it's base classes.
