@user71481 The way your question is worded is not doing you any favor. The two questions, about Android Studio, and "How to add a timer?", make it sound like you are looking for advice on code not written yet. If you remove those, and write a few short sentences to explain what it does (e.g., game starts, then measures how fast you can swipe the mouse" it would fare much better. — sᴉɔuɐɹɥԀ23 secs ago
That's ok @nhgrif I posted a wildly unpopular answer about a badge proposal that I think would have been well received if it was on MSE instead of MSO.

search("Steve");
> No match found for Steve No match found for Steve
func search(name: String) {
for friend in friends {
if friend == name {
// friend found
return // <-- return out of function and stop looking for your friend
}
}
// friend cannot be confirmed as unfound until this point
}

I created a new project and when I run it, it brings an empty window with a simple menu file/exit. but in the project files the only thing I have is foo.cpp

@mjolka Thanks Mat. I have use PInvoke in the past. In this situation it gets really messy to do so and the project is suppose to have a really minimal gui. So I guess it's in my favor to learn how to make a little GUI in C++ win32 rather.
However I have a question about PInvoke if you have used it in the past.
I have two DLLS, say FooD and BazD
the function I need to access is inside FooD and is called Foo()
I can do that using [DLLIMPORT FooD] following by the command to access Foo() in the next line
however, for the Foo() to work the 2nd DLL (BazD) needs to be in the same path and registered and I don't know what to do to make that happen
I can't really do [DLLImport BazD] as there isn't any function inside it that I need to access

@Mehrad this seems to work: right-click project -> Add -> Existing Item -> select BazD.dll -> click Add As Link from Add button drop-down. make sure BazD.dll has build action Content and Copy to Output Directory is either Copy always or Copy if newer
@mjolka I have dropped that dll in the debug folder and it worked. So I guess what you're suggesting will have that dll for keeps and sort out my problem
cheers
@mjolka that wokrs
I should find out what is add as link

That totally helped. using the same method I have added my main dll (FooD.dll) as well and now I don't need to address it with the full path. really appreciate it.

"So any tips to optimize this code?" Stackoverflow is not for optimizing code. Ask on Codereview instead. "It took 3 Hrs for me to write this can I be a developer?" Everyone can call himself a "developer", so yes you can. A different question is, can you become a good developer and this is something we can't answer.

That specific recommendation not withstanding, I actually think SOers are getting pretty good about recommendations and it might work to have CR as a migration target soon-ish.
They have been trained, in very large part thanks to @Duga.
Still showing "days in beta" on Area 51. Still showing stats on main page. Still don't have migration paths. All of that says that we're still in beta. We might be eligible to graduate. We might be on the cusp of graduating. However, we have not actually graduated in any real or meaningful way.

I wonder what's worse though, a question being incorrectly migrated because the migration path exists? Or an on-topic question getting closed because people think that's the correct action when the migration path doesn't exist.
The migration path needs to exist, but users should have to have a certain amount of rep on both the source and destination sites before being able to vote for migration. That's the real answer.
If you can't vote to close something as off-topic on the destination site, then who are you to say this question is definitely on topic there and should be migrated there?
If CR shouldn't have a path from SO, then no site should. That some sites do encourages the thought that migration should be handled through the close vote screen and encourages people to close questions that have no business being closed.
Vote to close if it's off-topic, other wise flag for migration.
Or actually, don't flag for migration. Only questions that have been closed should even be considered for migration. The first criteria for migration is that it be off-topic on the source site.
Once it's closed as off-topic on the source site by trusted users of the source site, it can be nominated for migration by any user. Then when destination site receives a nomination, trusted users of destination site vote on whether to accept and open at destination (or edit, accept, and reopen)
@nhgrif that would be a bit of a cumbersome process. IMO the option to "vote to close & migrate" should exist right from the start. Otherwise there will be a drastic reduction in migration, everywhere, because people can't bother to migrate closed questions.
I know. I'm just saying that if questions have to be closed first and migrated later, I don't think there will be many migration votes at all. No one will care because the problem is already dealt with - the question is closed.
Unless it is a particularly good question for destination site.
Which fits one of the other migration criteria: don't migrate crap.
People on SO often vote for migration just to get the question closed by whatever means. It's why crap gets migrated away from them to Programmers and elsewhere.

@RubberDuck I know the "yield" keyword uses a lot of "goto" behind the screens. Whether or not that's a valid reason for the keyword to still exist, perhaps we'll find out in the article.
@Quill is there really a valid markdown, such as [codereview] available for CR? I think I have tried in the past, but never got it to work. Or do you mean that they should use [at Code Review](http://youknowthelink.com)
@Legato Upvoting, while warming, won't really help the user being allowed to comment. Mentioning that the user should gain 50 rep before commenting is more proper, and a flag for comment-conversion is still good. We can't leave non-answers lying around.
