Hi guys
If I run a program in a DOS console, what should I do to have the time displayed on screen as the program is running:
1) without overhead time
2) without a zillion numbers scrolling down the screen but as a neat counter that sits tight on one single place.
Thanks!

You could use the backspace (^H, ASCII 8) character to return to the start of the line in order to overwrite it.

I recently ran into the situation where a bitmap displayed different results for pixels (255, 0, 255 vs. 248, 0, 248) on a desktop PC and a pocket PC. I've looked around for comments on this but haven't found anything. Does anyone have any information as to how this is possible????

If any of you ever typed "///" in a c# document...it'd generate these nice xml summary blocks.
Are their any extensions to vs.net that do this sorta stuff to c++?
|
|
|
|
|
O btw...are their any plugins that add the collapsable regions of c# for c++ documents :P

In VS.NET 2003, go to Tools, Options, Text Editor, C/C++, and check the "Enter outlining mode when files open" box.

lets run a dos window (command.com) then type "sort" (then press return key).
the dos window blocks there (until we input complete command for "sort").
at this stage, can we terminate the "sort" command or exit dos window without pressing close button of the dos window? - i mean, terminate the dos window only by tying some command ot text?
================================================
this is a VC question actually.
I use an app to CreateProcess of the command.com.
but once the dos blocks there (i.e. in the middle of sending command "sort"), my app can not terminate the dos window - i have tried all functions (such as TerminateProcess, RxitProcess).
i think if i can terminate the dos by command as described above, i can terminate the dos in my app also.
thx

when u use createprocess to run command.exe are u using the process handle in the return PROCESS_INFORMATION structure to TerminateProcess() ?
also sort.exe is another app which is spawned by command.exe, so TerminateProcess() doesnt hav the process handle of sort.exe it only has command.exe.
maybe try using createprocess to run sort.exe instead?

When I run my VC++ program (both Console and Windows version), I noticed that the "Mem Usage" (under Processes in the Windows Task Manager) ALWAYS increases by 4K every time my program executes. Is this normal? I didnt use any dynamic memory creation (using "new"), but can this be a memory leak?
I let the program sleep using "Sleep(xxx), and I use FileMappingObject... Can this be the reason??

Your program's private bytes would be cleaned up upon exit anyway. You should see what your program does. Maybe you leaked some system resource or other shared resource, which might not get recovered until the system restarts.
|

The program will be running for weeks on end. Also, I use FileMappingObject every time the program runs (in this case, every 2 seconds). Every time this happens, it increases by 4k. Can this be related to opening files, or using FMO??
Thanks!

You need to UnmapViewOfFile those FMO when you are done. Also make sure to CloseHandle the FMO's 'file' handle after unmapping the view to it. There is no reason you could not run 'indefinitely' if the proper cleanup is performed.
We use FMO in our apps, and our apps run for months at a time.

I am writing a c++ program to encrypt/decrypt files. my instructor wants to start this program by right clicking on the file to be encrypted/decrypted and then choosing the option Encrypt/Decrypt among the list that appears when any file is right-clicked. Can anyone help me with that?
|
|

|
|
Meaning you probably need a context menu handler that responds to all file selections.
Selection of items from the context menu will invoke your program to encrypt/decrypt the selected file(s).

okay...i have written a program that calculates prime number till u stop the program. Now, what happens it that while calculating the numbers or calculating any mathematical equation for that matter, the program only manages to use a small portion of the CPU. How can i utilize the whole CPU. SOmething like multithreading. In basic terms, i want to calculate the number as fast as possible!!

What is it your program does that it does not consume more CPU time? If you had a tight loop performing only math, then your program should be using a LOT of the CPU time as the foreground process. In this case it does not make sense to split into multiple threads, you would just be wasting more time switching the context. Do you output to screen or wait for user or something? Typically you only multiple thread if you need to handle user input while calculating something, or your program responds to user input while checking mail, or waiting for characters from the modem, or reading and writing to the files on the hard drive or something else like that, where there are distinct different actions, some of which involve 'waiting' for soemthing. Your program seems very straight forward and should probably remain single threaded.

yeah, youre right. In a tight loop it does use all of the CPU.
