Slider Control, Force Ticks

Hi,

I've put a slider control into my window and set a range (min/max). I've also set a TickFreq.

The Ticks are also correctly displayed, but it is still possible to drag the thumb to any position on the slider, not only where the ticks are (btw: auto ticks is on).

I've found not method to force the slider use only the positions where the ticks are. Is there any? Or do I have to code that stuff for myself.. ( I cannot believe that Smile | :)

).

Thx, Shi

If you had a slider from 0 to 100, and ticks every 10, then the slider will give the user 100 positions it can be.

Or, set a slider from 0 to 10, tick at intervals of 1, then just multiply the position by 1 internally.

Tada!

Iain.

Process memory access

Hopefully somebody might be able to help me with this before the weekend sets in.

I'm trying to manipulate the memory of another process. So far I can change the protection, read and write data. But two of the APIs VirtualAllocEx() and VirtualFreeEx() fail nomatter what I try to do.

I am doing nothing out of the ordinary, I simply create a process in suspended state, get the base address of it's memory and manipulate it; similar to most code injection articles.

Is there anything special I should be doing before I use these?

Whatever you do, it *should* not work. If it does, it is a temporary faiure in Windows security.

You may need to enable debug privledges.

Something like this:

LUID luid;
HANDLE hToken;
TOKEN_PRIVILEGES tp, otp;
DWORD dwSize = sizeof(TOKEN_PRIVILEGES);
if(OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY,&hToken))
{
	if(LookupPrivilegeValue(NULL,SE_SYSTEMTIME_NAME,&luid))
	{
		SecureZeroMemory(&tp,sizeof(tp));
		tp.PrivilegeCount = 1;
		tp.Privileges[0].Luid = luid;
		tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
		if (AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES),&otp, &dwSize))
		{

//TRY YOUR MEMORY WRITING HERE
//NO GUARANTEES, -DAVE
		}
	}
	CloseHandle(hToken);
}

Best regards,

Sorry, I forgot to mention I had already done that.

Through trial and error, I have found that I must let the system decide where to allocate the memory. Though calls to VirtualAllocEx() with MEM_DECOMMIT still fail, as does VirtualFreeEx(). I'm guessing this must be some type of security feature and only the caller to VirtualAlloc may de-commit or free.

This is unwise as any change to that volume would render the app un-runnable. There are any number of ways in which this ID could be changed. If you intend to use any ID from a PC, always take it from a physical item.

HDD ID was used for this purpose when I was coding for DOS applications (many years before). May be due to that my first choice is HDD. Big Grin | :-D

I have no idea whether the mother board ID, etc is available at that time. Do you have any knowledge regarding this?

You can use it...but don't tell you are doing that.
The best is to mix that ID with other information like CPU ID, motherboard, ...
But comes other problems: not every CPU has got the ID Cry | :((

At the end I think that I sure way is doesn't exist Unsure | :~

For complication, I used to use HDD ID combined with user name, etc. Smile | :)
