c# - why WaitForExit() doesn't wait? -

-

i adding custom action vs2008 setup project (msi installer).

i calling batch file create database , want delete files after. have waitforexit() not wait. why?

            processstartinfo startinfo = new processstartinfo();             startinfo.useshellexecute = false;             string tempdir = @"c:\temp\";             startinfo.filename = tempdir + "sybasedb\\en_allinone_installdb.bat";             startinfo.arguments = tempdir + "sybasedb\\";              try             {                 process startdb = process.start(startinfo);                 startdb.waitforexit();              }             catch (exception e)             {                 //do something?             }             {                 system.io.file.delete(tempdir);             }

no difference startinfo.useshellexecute = true; batch executed without problem because require user input , input y , n questions. delete action happened before input. , have pause @ end of batch file. can watch process of batch file going.

edit: tested more 10 times, didn't work. after lunch, put 1 more waitforexit , while loop hasexited check. sleep inside while loop. found worked. deleted code, 1 waitforexit. seems work now.

this throwing exception because can't execute .bat file. intend execute cmd.exe giving .bat file command line argument.

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() .

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
