something strange happened in pc (i suspect windows update did it). me , team working on windows forms project (targeting .net framework 4.0 client) past few months. fine until of sudden, vs 2017 started telling me .net framework 4.0 not installed on system, here screenshot: we cannot upgrade target framework because need support windows xp , .net framework 4 last 1 supported in xp. fortunately, in development machine .net 4 still available, here screenshot: but, in machine case this: .net 4.0 missing in link microsoft: https://www.microsoft.com/net/targeting so, here question: is microsoft intentionally removing .net 4.0 , other old frameworks windows 10, or bug in machine? any appreciated. thanks!

i have 1 excel file in row contains few cell string , other numeric, hyperlink. i want read data excel wrote below code hssfcell cell =row.getcell(j+1); cell.setcelltype(celltype.string); string cellvalue = cell.getstringcellvalue(); above code reads numeric cells , string cells when comes cells contain hyperlink, in case, reading cells null.i can put hyperlink between double quotes("abc@cd.com") in sheet want handle on code level. there way handle scenario? you should use cell. gethyperlink() hyperlink cell. if(cell.getcelltypeenum() == celltype.string){ hyperlink hyperlink = cell.gethyperlink(); string value = cell.getrichstringcellvalue().getstring(); if(hyperlink == null) { return value; } else { return value + " " + hyperlink.getaddress(); } }

so new spring boot, part of project scrap websites , operations on data scrapped, spring boot rest way expose data wondering when , can run pure java programs inside of spring boot project, idea came mind call programs inside of class implements commandlinerunner follows : public class myclass implements commandlinerunner{ private otherclassrepository otherclassrepository; public myclass ( otherclassrepository otherclassrepository ) { this.otherclassrepository = otherclassrepository; } //do operations , webscrapping programs created in other classes //guatering data @override public void run ( string... strings ) throws exception { //pass guethered data "otherclass" , expose } } and of course have controllers, repositories , entities. know if way , other ways work.

the datasheet tda93xx (an 80c51 based controller used in tv) on page 3 says can have: 32 - 128kx8-bit late programmed rom i wonder means? there chance me reprogram it? it means rom programmed before being encased variety of different methods. not mean device reprogrammable: u.s. pat. no. 4,295,209 discloses late programming igfet rom by ion implantation through openings in overlying phosphosilicate glass layer before metallization . ion implantation done through polycrystalline silicon gate electrode of selected igfets in rom. small size in rom preserved in u.s. pat. no. 4,295,209 incorporating silicon nitride coating beneath phosphosilicate glass layer. consequently, when implant openings etched in phosphosilicate glass layer, polycrystalline silicon gate electrode not exposed. accordingly, metal lines can cross directly on implant openings without contacting gate electrodes. however, silicon nitride coating ordinarily thin , there can capacitive coupling...
