c# - How can I open a Microsoft Word document from within a winforms .exe app? -

-

i have winforms app utilizes dll (docx) create .docx document stringbuilder. i'm trying open document microsoft word (the default program) button click. tried folowing code keep getting errors. can point me in right direction accomplish this?

private void button3_click(object sender, eventargs e)     {         var x = "";         using (docx document = docx.create("testdocx.docx"))         {             document.margintop = 25f;             document.marginbottom = 25f;             document.marginleft = 25f;             document.marginright = 25f;             paragraph p = document.insertparagraph();             fontfamily fontfamily = new fontfamily("courier new");              p.append(sb.tostring()).font(fontfamily).fontsize(8); //where "sb" stringbuilder             document.save();             x = environment.currentdirectory;         }         processstartinfo startinfo = new processstartinfo();         startinfo.filename = @"c:\program files (x86)\microsoft office\office12\winword.exe";         startinfo.arguments = x + "\\testdocx.docx";         startinfo.useshellexecute = true;         process.start(startinfo);     }

your approach hard-codes path winword. while may work case, inflexible , brittle.

you can instead do

process.start(x + "\\testdocx.docx");

that find default document handler .docx files (which winword, assuming installed , have not installed else handles .docx files).

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
