i writing standard windows app in delphi 7. if writing console app, can call following output cmd line or output file. writeln('some info'); if standard gui app have started command line error. i/o error 105 there must simple solution problem. want app have 2 modes, gui mode , non-gui mode. how set correctly can write cmd window? this question similar (if not same) trying accomplish. wanted detect if app executed cmd.exe , send output parent console, otherwise display gui. answers here helped me solve issue. here code came experiment: parentchecker.dpr program parentchecker; uses vcl.forms, sysutils, psapi, windows, tlhelp32, main in 'main.pas' {frmparentchecker}; {$r *.res} function attachconsole(dwprocessid: integer): boolean; stdcall; external 'kernel32.dll'; function freeconsole(): boolean; stdcall; external 'kernel32.dll'; function getparentprocessname(): string; const buffersize = 4096; var handle...

i made script in ruby uses mechanize. goes google.com, logs in , image search cats. next want select 1 of results links page , save image. my problem links of results shown empty strings im not sure how specify , click them. here output of pp page can see links im talking about. note first link suggested links, can click because have title "past 24 hours" second link actual result search cannot click. #<mechanize::page::link "past 24 hours" "/search?q=cats&hl=en&gbv=1&ie=utf8&tbm=isch&source=lnt&tbs=qdr:d&sa=x&ei=t8kduu7ab4f8iwkzx4hobg&ved=0ccqqpwuoaq"> #<mechanize::page::link "" "http://www.google.com/imgres?imgurl=http://jasonlefkowitz.net/wp-content/uploads/2013/07/cute-cats-cats-33440930-1280-800.jpg&imgrefurl=http://jasonlefkowitz.net/2013/07/slideshow-20-cats-that-suck-at-reducing-tensions-in-the-israeli-palestinian-conflict/&usg=__1yeuvke4a9r6iirkcz9pu6ahn8q=&h=8...

i have gridview associated sqldatasource . when click button , change selectcommand , use databind update gridview . after postback, want latest data remain, don't want gridview loaded original selectcommand . i know done called viewstate , didn't manage implement in right way. i tried both enableviewstate="true" , enableviewstate="false" on grid itself, no luck. code <asp:gridview id="gridview1" ...... datasourceid="userssource" > <asp:sqldatasource id="userssource" ... selectcommand="select * users"></asp:sqldatasource> on startup, gridview filled results of select * users . now click button , following: userssource.selectcommand = "select * users user_id = 1"; gridview1.databind(); the gridview filled new data. now let's say, click on header sort table, there postback, , after it, data in table contain results of first query. what needs done here?...

i want multiply 2 int numbers and, in order prevent exceeding int limit (2147483647), result saved in long long variable. so, try piece of code: int a, b; long long result = * b; and it doesn't work! if a=50000 , b=50000 result=-1794967296 . therefore, have apply type casting a , b : int a, b; long long result = (long long)a * (long long)b; why necessary apply type casting in case? note: don't want change data type of a , b , need keep them int . since a , b int , product a*b int also. product big overflows , incorrect value.the cast needed product long long . by way, don't need cast both operands. 1 enough: long long result = * (long long)b; the other 1 promoted long long also. see this online demo . by way, prefer c++-style cast on c-style cast: long long result = * static_cast<long long>(b); hope helps.

i'd replace every other (odd?) space x . result should be: axb axb axb axb axb i tried like: replace ("a b b b b" , " " , "x")[position() mod 2 = 0] -- no result. first of all: fn:replace requires xpath 2.0 (or xquery) compatible query processor. you cannot use fn:replace predicate this. there no array-like access characters in xpath (like you're used eg. c). solve using fn:tokenize , for-loop, that's getting things rather complicated. your query did not return result, there 1 result (single element string sequence), predicate returns every second. use regular expression instead. expression matches on non-space ( \s ) , space ( \s ) , replaces patterns version x in between. star quantifier in end important odd number of match groups (like in example). replace("a b b b b" , "(\s+)\s+(\s+\s*)", "$1x$2")

i have application in using both navigation bar,and toolbar(at bottom).both having shade center bottom.this how creating toolbar` [self.navigationcontroller settoolbarhidden:no animated:yes]; self.navigationcontroller.toolbar.barstyle = uibarstyleblackopaque; self.navigationcontroller.toolbar.frame=cgrectmake(0, [[uiscreen mainscreen] bounds].size.height -12, [[uiscreen mainscreen] bounds].size.width,30); self.navigationcontroller.toolbar.tintcolor=[uicolor colorwithpatternimage:[uiimage imagenamed:@"top_bar.png"]]; and doing navigation bar this uiimage *navbar = [uiimage imagenamed:@"top_bar.png"]; [[uinavigationbar appearance] setbackgroundimage:navbar forbarmetrics:uibarmetricsdefault]; ` can point me in going wrong? i think easiest way create 1x1 uiimage , set background image navigation bar , toolbar. eliminate gradient , make both bars 1 solid color of choosing. here's example: uiimage *image = [self imagewith...
