Hi All,
I’m developing a function driver 64bit, on “Windows 64 bit Standard Edition”.
I encountered with two issues:
1.Failed to pass pointer buffer (more then 16 Mb size) from 64 / 32 bit application To the 64 bit Driver (probe & lock mechanize fails).
2.Failed to map in 64 bit Driver more then 1 Gb memory (using MmMapIoSpace api).
I will appreciate your assistance.
Thanks.

Where to get source code of any example of race condition. I need to simulate it using some sample. I tried to google it but not succeed. If any body having any idea would be better.

<br />
CAR raceCar = new CAR();<br />
CAR raceCar2 = new CAR();<br />
<br />
raceCar.WaitForStartFlag();<br />
raceCar2.WaitForStartFlag();<br />
<br />
while(RACING)<br />
{<br />
raceCar.RACE_!!!_();<br />
raceCar2.RACE_!!!_();<br />
}<br />
<br />
this is my old race condition codez sample

this is pretty easy .. create a console app with two threads. one of them prints out 10xA, the other one 10xB.
Don't try it, just do it!

I need urgent help regarding this.can anyone please convert this algorithm into c++ program.Its very important for me..pleaseee 
Staff Removal Algorithm.
procedure
STAFFLINEREMOVAL(IMAGE,STAVES)
threshold = 2∗staffHeight;
tolerance = 1+ceil(staffHeight/3.0);
IMAGE REMOVE = copy(IMAGE);
for nvalid = 0 to STAVES size do
Point2D staff = validStaves[nvalid];
for i = 0 to staff size do
col =staff[i].x;
refRow =staff[i].y;
row = refRow;
pel = valuePixel(IMAGE,IMAGE REMOVE)
decrement/increase the reference row until one
pixel different from white pixel (dist1/dist2) is found;
if dist1 ≤ max(1,min(dist2,tolerance)) then
refRow− = dist1;
else
if dist2 ≤ max(1,min(dist1,tolerance))
then
refRow+ = dist2;
else
continue;
end if
end if
Count the number of decrements/increase on
the reference row until the black pixel changes to white
pixel (run);
if run ≥ threshold then
continue;
end if
remove the vertical black sequences on the IM-
AGE;
end for
end for
end procedure

That doesn't look too hard.
How far have you got doing it yourself? What are you having problems with?
Have you written any code to try to do it?

Actually i tried writing but im not so proficient in c++.But it is compulsory to write in c++ so im helpless.Please do the needful.I shall be very grateful

Why not try, and see how you get on ? There are plenty of people on here who will help on specific problems, but they won't do your homework for you !! (You wouldn't learn anything that way, would you ?)

Why is it "compulsory" to use C++?
If it's for a college course, you should be learning what you need, not relying on others to do your homework.
If it's for your job, you should only be taking on work you're capable of doing, or explaining to your boss that you don't have the ability for certain tasks.
Whatever the reason, if you want someone to do work for you, then you're going to have to pay them for it. I don't work for free for my company, and I've no intention of doing it in my spare time.

Its not my homework and neither do i need to learn c++.Just cuz the person who wants to see the implementation wants it in c++..I dont have much time to learn complete c++ and write the program.Its a small help.Thats it
|
|
|
|
|
I have to do the whole project so im definitely not dumping my work on you.Just the c++ part,im not good at it and mainly theres no time.Here i thought people would help cuz its a small task.Do you really expect people to pay?

Why is it so urgent if it's not homework or part of your job?
Its not my homework and neither do i need to learn c++.
Maybe you do need to learn C++ if you want to do this.
Just cuz the person who wants to see the implementation wants it in c++
And who is this mysterious "person", if it's not your tutor or manager? Why does he want you to do it? Why can't he do it himself? Why did you tell him you could do it if you couldn't?
I have to do the whole project so im definitely not dumping my work on you.Just the c++ part
So it's a project of some sort? And why is there a "C++ part" - what kind of a project is it? Presumably multi-language, so why did you take it on if you couldn't do it?
Why is it so important that this particular part gets written in C++?
If it's homework, then presumably you're supposed to learn C++. If it's part of your job, presumably you've been employed on the basis that you knew C++. If it's a home/hobby project, why try to use a language you don't know?
Here i thought people would help cuz its a small task.
People here are more than willing to help if those they are helping are willing to put in a bit of effort. If you'd tried to write it and posted your attempts, explaining where you had problems, you'd probably have had several answers by now, and have completed the task. Just asking "please send me the code" is making no effort, rude, and very unlikely to get any help at all.
Do you really expect people to pay?
Do you really expect people to do your homework, or as seems more likely, your job for you and not get something for it?
I'm not trying to be nasty here, just trying to make you understand that you can't expect to have everything in life handed to you on a plate, and usually you have to work for it. A bit of effort on your part will not only solve whatever problem you're working on, but also increase your own level of knowledge, which will undoubtedly be of use to you in the future...

hi,
write now i getting time from a mail. and this time is in the form of system time. First of all i am getting this time as file time from the i converted that into system time so that i got time.
Now i want write this into mail again for that I wrote like follows
SPropValue prop;
SYSTEMTIME sTm={1220,12,11,12};
FILETIME fileTime;
SystemTimeToFileTime(&sTm, &fileTime);
prop.ulPropTag= PR_LAST_MODIFICATION_TIME;
prop.Value.ft=fileTime;
But it is not working
If the process is wrong just show me the solution
thanks in advance.

if (FAILED(hr))
{
if (lpAttach)
lpAttach->Release();
pNewMessage->Release();
return false;
}
enum {SUBJECT, CLASS, BODY, MSG_DEL, MSG_PROPS };
// Message properties tag array
SPropValue lpPropValueArray2[MSG_PROPS];

hi all
i have programmed code to generate an .exe for drawing a plot of a mathmatic function dynamically by vc++ api.
now i am testing the stabilization of this .exe programme.
and i found that when the graphic window,drawing the plot, has been refreshed ( i redraw the plot by call InvalidateRect (hwnd, NULL, TRUE) ; ) for 12 times the .exe code will be crashed down. that is to say no response to the mouse click or close. and i have to shut the .exe down by ending its processe in task manager.
anyone has come up against this situation? please help me or give me some advice.
your help will be appreciated

Sounds to me like you are leaking GDI resources. Use the task manager to check how many GDI objects your app hanging on to after every draw.
You may be right
I may be crazy

wow that is it GDI leaking. i have check my code. insert lines of ReleaseDC and DeleteObject. then the .exe is running well.
Thank you very much!! appreciate for your advice. thank you.

Yes u r right, thanks a lot. i found this article very helpful but also am still creating a dll in which
i attach a detour to system call and make it mycall, this is very clear. but how can i inject this dll into
all running processes at the same time, every example here r talking about specific process "messenger" or "notepad", i know that am very noob but i need this so much. PLZ help me again.
