c++ process start problem with path

I'm using process::start(PATH); to open up the process. The problem is, sometimes 开发者_C百科it finds the file and sometimes it doesn't.

For example, this works:

process::start("C:\text.exe");

But this doesn't work:

process::start("C:\New Folder\text.exe");

Any idea what the difference is?

You have to escape the \ characters.

In a C string \t is the TAB character. Use:

process::start("C:\\New Folder\\text.exe");

The library might think that c:\New is the program you are running, and Folder\text.exe is an argument you are passing to it.

You might need to quote it, so you're calling this:

"C:\New Folder\text.exe"

Which as a C++ string would look like this:

process::start("\"C:\\New Folder\\text.exe\"");
