In Visual Studio 2008: Is there a way for me to customly collapse bits of code similar to like how I can automatically collapse chunks of comments?

A:
Your piece of code needs to be a block surrounded by, as desired:
- braces
#regionand#endregionin C##pragma regionand#pragma endregionin C/C++
If you can't collapse statement blocks, you need to enable this feature :
Tools -> Options -> Text Editor -> C/C++ -> Formatting -> check everything in "outlining"
Then, reopen the source file to reload outlining.

Hmm, well it works, but unfortuatly it is essentaly commenting the entire chunk of code out of my program. I want to be able to collapse working code. This is especialy usefull when i want to add a condition (an if statement) to activate a large chunk of code without putting it into a function (it dosent work as a function, so i dident make it as one).

If you're using an if statement, then you already have a collapsable block. So I don't get it. Btw, #pragma region keeps the code and enables you to collaspe working code, just as you need I guess.

Its more of like putting in new if statements. There are simply too many loops in my program (i think its at around 10 nested loops + a whole bunch of other if statements) and its beocmming hard to keep track of what is inside of what. How do i collapse loops and if statements?

I'm not sure why you think it is commenting out the code. You should be able to use the #pragma regions statements to create collapsible chunks of working code.

@Faken, ok now i get it, automatic outlining of statement blocks is not enabled by default in C++. i've edited.

TheSam is right, you can create collapsible chunks with the #pragma region and #pragma endregion statements.
Here is a sample:
int main(array<System::String> args)
{
Console::WriteLine(L"This");
Console::WriteLine(L"is");
Console::WriteLine(L"a");
#pragma region
Console::WriteLine(L"pragma");
Console::WriteLine(L"region");
#pragma endregion
Console::WriteLine(L"test.");
return 0;
}
In the above sample, everything between the samples can be collapsed.
You can also specify what text is displayed when it is collapsed. You can do that like this:
#pragma region The displayed text
That would obviously display "The displayed text" when the region was collapsed.
