Hi,
What is the best method to record the location of a file, so that
the file can be located later even the user has changed the file location ?
(beside using a file system watcher to notify the file location change, coz it would take up certain resources)
Thanks

Deployment (C++)[^]
If you can statically link to the CRT (and MFC if necessary) libraries you may be able to run
your EXE stand-alone on another system, if it doesn't need other DLLs.

It looks like your debug build was non-Unicode and your release build is set to use Unicode.

Hi,
i added a TreeCtrl to my Dialog.
The properties are standard exept of checkbox = true, hasbuttons = true, haslines = true and linesatroot = true.
the problem is, if i start the dialog with the treectrl, i have a scollbar on the bottom of the tree ctrl, but the list is empty.
even if there are items in it, the scrollbar is there an it is very long.
if i disable the ckeckbox-property, the there is noch scrollbar.
trying to check an item via setcheck(item, 1) fails!!!
any idea???
i already deleted all files and restart and so on.
all the other treectrl in the project which are done before work fine.
i use vs2005 windows xp sp2

I don't know if this is related to your checkboxe problem...
From the docs:
"If you want to use the checkbox style, you must set the TVS_CHECKBOXES style (with
SetWindowLong) after you create the tree-view control and before you populate the tree.
Otherwise, the checkboxes might appear unchecked, depending on timing issues."

If you do not want to use the boost libraries as suggested you can create simple trim functions using the find_first_not_of(), find_last_not_of() and substr() functions.
std::tstring::size_type trim_left(std::tstring &string, const std::tstring &chars = _T(" \t"))
{
std::tstring::size_type pos = string.find_first_not_of(chars);
if (pos != std::tstring::npos)
{
string = string.substr(pos);
}
return string.length();
}
std::tstring::size_type trim_right(std::tstring &string, const std::tstring &chars = _T(" \t"))
{
std::tstring::size_type pos = string.find_last_not_of(chars);
if (pos != std::tstring::npos)
{
string = string.substr(0, pos + 1);
}
return string.length();
}
std::tstring::size_type trim(std::tstring &string, const std::tstring &chars = _T(" \t"))
{
trim_left(string, chars);
return trim_right(string, chars);
}
You may be right
I may be crazy

I've tried this for quite a while, still clueless. 
I used WNetOpenEnum and WNetEnumResource to obtain the IP address of other PC connected to my neighborhood. Now I want to know the subnet mask settings and gateway settings of them. What functions to use?
I know structure INTERFACE_INFO contains field iiNetmask, which is the network mask, but which function can give me this structure as an output?
thank you very much for the help!

Hello Friends
Can someone please help me with a question regarding the SDK
Now Microsoft has comeup with a new SDK
a) If i compile any sample application , will it work on old OS (eg Win 98 , etc)
b) How i can find out what files need to be redistributed & where to find them?
Regards

a) Not necessarily. If the sample app is demonstrating APIs that became available on Windows 2000
then it's probably not going to run on Windows 3.1.
b) Deployment (C++)[^]

Hi,
I have data coming at a really fast rate 200 times a second. I have a consumer which runs slower then the producer, and I need to have the ability to keep the data being copied off for a long period of time, namely like for 3 to 4 hours. Now the way that it is going now I have this circular queue, but because the consumer runs slower, the producer overlaps it and I lose data and everything gets off sync. I can not lose any data, and I need to be able to write the data for 3 to 4 hours, is there any way that I can do this.
Thanks in advance

of course, you lock the shared resource (here, your circular queue") so that only one can use it at a time (either producer, or Consumer, but not both), and release it then.
you should document yourself about semaphore, mutex, and such security locking systems...
|

Thanks for the repsonse.
By doing the locking, wont you lose data? Since the producer wont be able to write the data in at the time that it is available?

thanksfully not !
actually, the producer (if it's the producer who wants to use the resource when it's locked) "hibernates" for a certain period, until the comsumer releases the resource.
the problem is if you don't release a locked resource... you can come into an infinite loop...

So right now what is happeneing is I have a hardware board hooked up to the computer and it throws out data 200 times a second. In the callback of the acquisition board I take the data and copy it into the circular queue. Now the consumer consumes the data at a slower rate, my estimate is 100 times a second, so because it is consuming the data at a slower rate, there will be a time where the producer will overlap the consumer in the circular queue. When this happens and there is a semaphore on it, the data will then be locked and hence I would lose the new data coming in from the acquisition board, would I? Or am I compeltely misunderstanding this
Thanks again

what you MUST implement however is a security which will forbid the producer to write in the queue if it's already full... it must wait for a consumer goes by there

Why a circular queue, and not a queue? Maybe even MSMQ[^]?

With a queue I thought I would over run the memory, and then cause the whole computer to crash.

The queue does not need to store items (entirely) in the memory. Again, look at MSMQ - it stores messages in files in the MSMQ\Storage folder.

You may also do this,
Use queue(STL,maybe) and mark the zone you push data into the queue [queue::push(msg)] using Critical section. That works, simple.
