entry-point

This is part of a series of at least two closely related, but distinct questions. I hope I'm doing the right thing by asking them separately. I'm trying to get my Visual C++ 2008 app to work without the C Runtime Library. It's a Win32 GUI app without MFC or other fancy stuff, just plain Windows API. So I set Project Properties -> Configuration -> C/C++ -> Advanced -> Omit Default Library Names to Yes (compiler flag /Zl ) and rebuilt. Then the linker complains about an unresolved external _WinMainCRTStartup . Fair enough, I can tell the linker to use a different entry point, say MyStartup .

What is the difference between the three functions and when to use them?? WinMain is used for an application (ending .exe) to indicate the process is starting. It will provide command line arguments for the process and serves as the user code entry point for a process. WinMain (or a different version of main) is also a required function. The OS needs a function to call in order to start a process running. DllMain is used for a DLL to signify a lot of different scenarios. Most notably, it will be called when The DLL is loaded into the process: DLL_PROCESS_ATTACH The DLL is unloaded from the

I need to find the assembly in which managed code execution started. // using System.Reflection; Assembly entryAssembly = Assembly.GetEntryAssembly(); This seems like the way to go, but the MSDN reference page for Assembly.GetEntryAssembly states that this method "[c]an return null when called from unmanaged code." In that case, I would like to know which assembly was called by unmanaged code. Is there a reliable way of doing this, i.e. one that always returns a non-null Assembly reference? The best I could think of so far is the following, which should work in a single-threaded scenario: //

How to setup alternate entrypoint in Blackberry Application.There will be 2 application UI Application Background Application: will run on autostart. There is a blackberry knowledge center article about this, which I tried, and coded as follows. But on clicking the application icon, there is no response. class EntryPointForApplication extends UiApplication { public EntryPointForApplication() { GUIApplication scr = new GUIApplication(); pushScreen(scr); } public static void main(String[] args) { if ( args != null && args.length > 0 && args[0].equals("background1") ){ // Keep this instance

Is it possible to avoid the entry point (main) in a C program. In the below code, is it possible to invoke the func() call without calling via main() in the below program ? If Yes, how to do it and when would it be required and why is such a provision given ? int func(void) { printf("This is func \n"); return 0; } int main(void) { printf("This is main \n"); return 0; } If you're using gcc, I found a thread that said you can use the -e command-line parameter to specify a different entry point; so you could use func as your entry point, which would leave main unused. Note that this doesn't

I've seen this in a few tutorials now... but how in the world can Android source code not have a main method and still run. For example (from http://developer.android.com/guide/tutorials/hello-world.html ): public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } That runs but there is no main!!! I've also thought that using things like onCreate (or formLoad, etc.) was bad becuase a constructor should do that work and such
