c# - How to get around storing a usercontrol out of process in session state -


i attempting store usercontrol in session state between postbacks, using sql stateserver.

i class not serializable error:

unable serialize session state. in 'stateserver' , 'sqlserver' mode, asp.net serialize session state objects, , result non-serializable objects or marshalbyref objects not permitted. same restriction applies if similar serialization done custom session state store in 'custom' mode.

stack trace

serializationexception: type 'asp.bookingcontrols_controls_ucdates_ascx' in assembly 'app_web_eckjngpu, version=0.0.0.0, culture=neutral, publickeytoken=null' not marked serializable.]

now, marking usercontorl class serializable, still error. research have determined, far, usercontrol cannot serialized. fine.

the general proposed idea around this, seems to split control (data) control (interface/front end), , rebuild on other side.

now, before attempt make impacting changes code, question following:

will object derived usercontrol class, not created dynamic usercontrol means of page.loadcontrol("control.ascx"), serializable, or have create seperate "accompanying class" store data. if so, assume can not inherit control class properties, inherit usercontrol classes not serializable?

example:

not using:

dim mydatescontrol new usercontrol mydatescontrol = page.loadcontrol("~/bookingcontrols/ucdates.ascx")          ctype(mydatescontrol, controls_ucdates)             .checkindate = session("nowcheckin")             .checkoutdate = session("nowcheckout")             .nights = "xxx"             .guid = currentbookingfilter.guid             .extrainfo = currentbookingfilter         end

would following work, object serializable out of process session state.

dim mydatescontrol new controls_ucdates          ctype(mydatescontrol, controls_ucdates)             .checkindate = session("nowcheckin")             .checkoutdate = session("nowcheckout")             .nights = "xxx"             .guid = currentbookingfilter.guid             .extrainfo = currentbookingfilter         end

in second block, mydatescontrol serializable?

nthe end result mydatescontorl class, inheriting usercontrol class, not serialized session state.

i created "accompanying" class , duplicated properties of uc. in code, use accompanying class store state control, , create controls before display, re-reassign properties.

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)...
