c# - Crystal report to send report directly to default printer -

i'm trying send report direct default printer , running ok code: doc.load(server.mappath("~\\reports\\crystalreport\\documentcrv.rpt")); doc.setdatasource(dsreport); doc.printtoprinter(1, true, 0, 0); the problem works when i'm running webapplication on dev machine (so, i'm assuming it's getting default printer server, not user's printer) there no way directly print users printer web server, unless possibly on same internal network / directory. management nightmare. your best bet pop open viewer , print dialog. i did use active x control enumerate end users printers , automatically print it. however, ie , poorly maintained.

rpmbuild - my RPM package requires 2 already installed shared libraries -

i'm looking making rpm packages. i created first rpm package rpmbuild. package simple. has copy several config files , 1 executable. i cannot install .rpm because 2 shared librairies used executable required. these librairies installed not linked .rpm package because build them 1 of projects. there located in /usr/myproject/lib directory. i tried put symbolic links /lib , /usr/lib, tried run "ldconfig" update .conf file contains /usr/myproject/lib directory, , tried update ld_library_path env variable without success. i know can ignore dependencies using -nodeps command line option i'd in next step create own yum repository yum not allow install package if dependencies not fulfilled. i prefer keep automatic dependency feature of rpmbuild enabled. thanks in advance. package these 2 libraries in rpm, can install both rpms in 1 rpm -i call.

Delphi function to convert Result of WrapText to TStringList -

i use function insert carriage returns on string nicely formatted emailing: m := wraptext(m, #13#10, ['.',' ',#9,'-'], 60); the problem email client has 1023 character limit when processing strings. if original length of m greater 1023, gets truncated (note: email client has events handle situation, think easier approach feed strings less limit). i looking " wraptexttostringlist " function this: var mstringlist: tstringlist; begin mstringlist := wraptexttostringlist(m, #13#10, ['.',' ',#9,'-'], 60); so passed 220 character body of email message. results string list approximately 4 entries. i think boils down creating function parses string @ #13#10 string list. anyone got one? tstringlist has built-in method parse string @ #13#10 string list. mystringlist := tstringlist.create; mystringlist.text := mystring; this populate list parsing string , creating new entry in list whenever finds r...
