visio c# get RGB-Color from a layer -

-

i try current color of layer in visio document rgb. problem colors, not set "rgb(1,2,3)" in formula. there colors set, based on current scheme. there colors "255" (layer color not chosen) or "19" (the used color depends on active scheme, eg. dark-gray).

i need way transform "19" rgb-scheme, depending on current scheme , variant.

heiko

visio has first 24 colors fixed. others come in form of rgb(r, g, b) formula. list of fixed colors can obtained form document.colors. in all, start following:

using system.drawing; using system.text.regularexpressions; using visio = microsoft.office.interop.visio;  static color getlayercolor(visio.layer layer) {     var str = layer         .cellsc[(short)visio.viscellindices.vislayercolor]         .resultstru[""];      // case 1: fixed color     int colornum;     if (int.tryparse(str, out colornum))     {         var visiocolor = layer.document.colors[colornum];          return color.fromargb(             visiocolor.red,              visiocolor.green,              visiocolor.blue);     }      // case 2: rgb formula     var m = regex.match(str, @"rgb\((\d+),\s*(\d+),\s*(\d+)\)").groups;      return color.fromargb(         int.parse(m[1].value),          int.parse(m[2].value),          int.parse(m[3].value)         ); }

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*...
