IIS and COM+ Partitions: Failed to create ASP Application XXX due to invalid or missing COM Partition ID -


i have application uses com+ components. trying make application work on multiple applications in iis. each application has own application pool. why need separate com+ components 1 each application. way isolate com+ applications use com+ partitions.

i created partitions in component services admin tool, on windows server 2008 r2 server. created partitions , created com+ application inside each 1 of them. in iis have separate websites run in different application pools. configure each website use partition , assign partition guid exists. after set iis partition guid , enable use partitions then, after iisreset, run website in browser , receive http 500 internal server error. looked event viewer , error message: failed create asp application xxx due invalid or missing com partition id.

if disable use of partitions in component services admin tool , disable usage of partitions in iis application works. need able use partition allow multiple websites run in same time these com+ objects.

after lot of research on subject have found solution: not use partitionid iis , not enable partitions iis either. leave them default values.

the solution following: each partition should assigned default partition 1 user , each iis application (and each app pool) should run on same users default partitions use. if have 2 iis applications named: web1 , web2, , 2 app pools: app1 , app2, 2 users user1 , user2 , 2 partitions: part1 , part2. web1 should run under user1 , app1 should run under user1 (app1 application pool web1). in component services user1 should have default partition: part1. when web1 search com+ component first try search in partition assigned user of iis application: user1. user1 has default partition part1 find it.

hint: enable com+ partitions on windows server 2008 r2 go component services > computer > right click on > properties > options tab > check enable partitions , other one: check local store when choosing partition user . partitions can enabled in windows server editions. option disabled in windows 7 , couldn't find way enable it.

hope helps.

do not forget add com+ applications under each partition , add users there users can access them. add users in partition roles , in com+ partition users directory, under computer in component services.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
