winapi - How to use RegDeleteTree to delete KEY_WOW64_64KEY key? -

-

i have tested regdeletetree() in 32bit program. delete key_wow64_32key key. there function regopenkeyex() specify key_wow64_32key or key_wow64_64key ?

i have tired code:

hkey key = null; if (regopenkeyex(hkey_local_machine, _t("software\\asd"), 0, key_read | key_wow64_64key, &key) == error_success) {     long d = regdeletetree(key, null);      if (d != error_success)     {         cout << "error" << d;     }     else     {         cout << "success";     } }

the output success key still exits in registry. i'm running on windows 7 vs 2013 , compiled win32 program not x64.

use regopenkeyex key_wow64_64key open 64 bit view of key. call regdeletetree passing returned key.

regarding update. ask read access when opening key. documentation regdeletetree states:

the key must have been opened following access rights: delete, key_enumerate_sub_keys, , key_query_value.

the fact call succeeds anyway makes me think process subject virtualization. need have manifest process forces uac elevation. use requireadministrator option in manifest.

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
