i have code in c# want use in other project (coded in c++). researched, need create .lib msvs creates .dll (i think..). think possible use .dll using loadlibrary() on c++ seems not friendly. 1 - can create .lib in msvs? if not, how can create it. 2 - best way integrate code? .lib or using .dll + loadlibrary()? the easiest option, honestly, use c++/cli. lets use both object systems (.net, , traditional c++ standard template library).

i using carrierwave (https://github.com/jnicklas/carrierwave). need make sure images conform maximum/minimum height , width? otherwise error should display. should handled in uploader class or in model (possibly through custom validation method)? you can validate image width/height on client side, not guarantee anything, because it's easy manipulate/circumvent. for user friendliness: check on client side , give warning before uploading. data integrity, check on server side after upload.

is keyboard shortcut or free addon in visual studio 2010 allows switch between header (c/c++ .h file) , implementation (c/c++ .cpp file)? visual studio not have built-in keyboard shortcut switch , forth. macro far best bet if want automate single keyboard shortcut. list of suggested options, see answers previous question . the add-in visual assist x provides feature shortcut alt + o (however, add-ins not supported express editions of visual studio). if you're trying avoid using macro, there alternative way achieve similar result, although two-click process: to switch header implementation: right-click a.cpp file , choose "go header file" context menu. to switch implementation header: right-click identifier declared in header , choose "go definition" context menu.

how can convert unicode value equivalent string? for example, have "రమెశ్", , need function accepts unicode value , returns string. i looking @ system.text.encoding.convert() function, not take in unicode value; takes 2 encodings , byte array. i bascially have byte array need save in string field , come later , convert string first byte array. so use byteconverter.getstring(bytearray) save byte array string, can't byte array. try following: byte[] bytes = ...; string convertedutf8 = encoding.utf8.getstring(bytes); string convertedutf16 = encoding.unicode.getstring(bytes); // utf-16 the other way around using `getbytes(): byte[] bytesutf8 = encoding.utf8.getbytes(convertedutf8); byte[] bytesutf16 = encoding.unicode.getbytes(convertedutf16); in encoding class, there more variants if need them.

how can copy 1 data column 1 data table new datatable. when try it, error column 'xxx' belongs datatable.? datacolumn = datatable1.columns[1]; datatable2 = new datatable(); datatable2.columns.add(datacolumn); thanks in advance you cannot copy datacolumns. you'll need create new datacolumn in new datatable same data type in old datatable's column, , need run loop bring in data old datatable new datatable. see following code. assumes datatables have same number of rows. datatable dt1 = new datatable(); datatable dt2 = new datatable(); dt2.columns.add("columna", dt1.columns["columna"].datatype); (int = 0; < dt1.rows.count; i++) { dt2.rows[i]["columna"] = dt1.rows[i]["columna"]; } also, if data copying reference types , not value types might want see if .clone() method available type, or make 1 yourself. doing 'this = that' in loop not work on reference types.

for reason header row not visible. using swingbindings.createjtablebinding bind pojo table. table showing rows header row not visible. if inspect jtableheader in table there , columns have names expected. jtable header properties: isenabled , isvisible set true. is there missing? i don't know swingbindings.createjtablebinding is, when use swing add table jscrollpane. table header used column header view of scrollpane. if not using jscrollpane, need create jpanel using borderlayout. table added center , table header added north.

i test one: [test] public void testcollectionassert () { var a1 = new [] { new [] { "a" } }; var a2 = new [] { new [] { "a" } }; assert.arenotequal (a1, a2); //collectionassert.areequal (a1, a2); collectionassert.areequivalent (a1, a2); } to pass. real case more complicated, solving 1 in generic way do. ideas? there's useful linq operator called sequenceequal() compares 2 sequences equality. sequenceequal() walks through 2 ienumerable<> sequences , verifies have same number of elements , elements @ same index equal (using default equality comparer). however, since have nested collections, need extend concept of equality apply them well. fortunately, there's overload allows supply own iequalitycomparer<> object. since it's awkward have define class provide equality semantics, i've written generic extension allows use delegate instead. let's @ code: public st...

my app being rejected marketplace because of requirement 5.2.4.c (back button must close menu or dialog , cancel navigation). i'm using listpicker silverlight toolkit , that's what's causing failure: pressing button when listpicker open goes instead of closing listpicker , cancelling navigation. this seems simple enough fix: if user presses button , listpicker open, close , cancel navigation. however, haven't seen way of programatically either detecting whether listpicker open, or closing listpicker. am missing something? how fix bug? one again, have asked question soon. answer here: http://silverlight.codeplex.com/workitem/7643

i have service .net using ftpwebrequest download images ftp server. have camera stores images on same ftp server. if service see image , tries download before camera has finished storing same image, 'not-yet-stored-part' of image appears grey (corrupted). question: how detect whether image ready download (stored completely)? if had control on sending service, implement using marker files. if sending service e.g. write ".finished" file when it's done, wait file appear. however, suspect not have control on software in camera. there few issues detecting whether camera has finished uploading, slow internet connection. i think best solution check changes in file size. monitor folder , see whether new files appear. then, if file size has not changed e.g. minute, should safe download file.

my last experience wcf 3.0 pretty bad, because of reverted using asmx. see wcf 4.0 seems provide better configuration model, concern wcf 3.0 had lot of timeouts on extended service calls, asmx these timeout values can configured through iis , accept negative integer value of -1. does wcf 4.0 default configuration support getting timeout values iis, or once again need configure timeouts handle extended web service calls take time complete (could 6 hours). thanks in wcf have configuration level control on timeouts on both servers , clients editing binding configuration. since wcf not designed coupled iis don't think can inherit timeouts iis might have set them in both places. check link documentation on basichttpbinding element (which used soap 1.1): http://msdn.microsoft.com/en-us/library/ms731361.aspx and 1 details on different timeout configurations in wcf: http://social.msdn.microsoft.com/forums/en-us/wcf/thread/84551e45-19a2-4d0d-bcc0-516a4041943d/ i have ...
