Question

Resident programs in memory using C

Asked by: fran_azofeifa

I want to know how could I do to simulate something similar that happens with programas like Messenger, or WinZip, that are still in memory when an user destroys it. (their icon is located below at the right of the computer).

Also, I would like that my program's icon, would stay below at the right of the computer, like Messenger, McAffe Antivirus and other programs.

How could I do this using a C program?

Thank you very much!.

Their program isn't still in memory after the user destroys it, that's just not possible.  What is happening is that when the user presses the close button, the application simply hides the main window, and adds an icon to the system tray.  

To add a system tray icon, you need to fill a NOTIFYICONDATA structure, and then call Shell_NotifyIcon() passing NIM_ADD as the first parameter.

U can use TSR ( Terminate & Resident in Memory ) Programs i.e. programs that can be placed in the memory for permanent.

Refer "Writing TSRs in C" book of BPB Publications ( written mostly by Yashwant Kanetkar though i m not sure ).

However, note that these TSRs work only in DOS Mode & not in Windows Mode since it frees all resources used by the DOS Programs wen switching back to Windows Mode. So practically, ur C Program cannot be minimzed to an Icon in the Taskbar, it vil just get destroyed wen u close the DOS Prompt Window.

Reply if u need more help with TSRs.

If you have more information about TSR, I would like to know about it.

Thank you, jinesh.

Sorry for being so late. Was kinda really messed up.

TSR ---> Terminate & Stay Resident in Memory

These are special kind of programs that execute & stay in the memory even after they have been terminated by TC. They were usually used to write programs that had to be continuously run in the background like "Checking Empty Disk Space", "Displaying Time on the Screen", etc., but they were occasionally also used to create harmless viruses, all of these before the advent of hard-core multi-tasking.

I had been searching for more info. abt TSRs on the Net & have found a few wich i vil posting shortly.

Meanwhile, reply with progress status on ur side.

Cheers !!!

fran_azofeifa, TSR is not you're looking for. You should concentrate on the first comment. However, if you need information about TSR just start here -> http://www.answers.com/topic/terminate-and-stay-resident . Also if you google, do not search only TSR because it is acronym for lots of things. "tsr terminate stay resident" (without quotes) will make you go.
