Why isn't an exception thrown when the right .NET framework version is not present? -

-

we have .net application targets .net 3.5. our clients run shared drive (very infrequently) in order have central config file location.

we have noticed if workstation accesses shared drive , runs program, not have .net 3.5 installed, nothing happens, no error, no exception, no log entry, doesn't launch.

  • why there no error message shown in windows clr?

  • is there can put @ beginning of code ensure proper error message displayed?

it not option run installer check prereqs, installing in 1 central location.

thanks.

ideally, wouldn't have have wrapper query .net version, seems program failing launch, , windows should reporting somewhere. can't believe silently fail.

try app.config;

<configuration>     <startup>         <supportedruntime version="v3.5" />     </startup> </configuration>

i nice little dialog, so;

 --------------------------- moreverfoo.exe - .net framework initialization error --------------------------- run application, first must install 1 of following  versions of .net framework:   v3.5 contact application publisher instructions obtaining  appropriate version of .net framework. --------------------------- ok    ---------------------------

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
