I have implemented this algorithm but for a specific application (a game in fact). But I was using hexagonal cells and the distance between two 'cells' was always 1 in my case.
So I think your implementation will be very different... But I can send you what I've done if you want to have an example... I don't have it here so I will send it to you when I'm back home. Just give me your e-mail adress.
Also, there are plenty of examples on the web and I think once I saw an example that was describing exactly the scheme you are asking for: the distance between two points is not equidistant (and there you'll have to play with the weight of the path between the two points).

I'm trying to programmatically adjust the playback volume of media files. Let's say u simultaneously play two .mpg files, one file plays at a very low volume, and the other plays at a very high volume.
does anyone know how the playback could be adjusted to 'equalize' the playback volume? without adjusting the device_volume, of course...
(currently using directshow, but any solution is welcome)
thanks

Hello. When i use .Net Framework 1.1 and i add any key event in text box. In program while i press ENTER, i hear a sound. Hod do i disable sound or override it?
I Use c++ and .NET Framework 1.1.4322

I have found a workaround. In keyPress event there should be e->Handled = true;, note that it can block all keys when active, so you must add at the end
if (e->KeyChar == 13)
{
e->Handled = true;
}
I also notice that this post shoud be in .NET Framework or in managec c++ catagory

Hello guys,
Requirement:My Application should work with any baudrate starting from 01- 256k ideally and i need to implement for 76800 baud with out fail.
Constraint:We are able configure the bauds from 0 - 9600 (all the numbers), 10400,14400,19200,38400,56000,57600,etc..... when i give different baudrate from the above list, the error comes is Invalid Parameter.
Question: Is there any work around to overcome this constraint.It's really urgent.
can someone through light on this.????
Thanks in advance.

Can any one offer any aletrnative solution ? or a way i could

You're doing something wrong. A CString can hold up to 2 billion characters.

Write exactly what you are doing, it will be easier to tell you whats wrong when i look at the code

in the header its just
CString m_str;
in the.cpp
in the constructor
its m_str(_T(""))
in the data exchange its
DDX_Text(pDX, IDC_ESTR, m_str);
then when OnOK is called i just do an UpdateData to capture the text, but it doesnt capture all of it
thanks

do you use a DDV() operation on your editbox ?

No, but i have added
DDV_MaxChars(pDX, m_str, 20000);
but all that will do it put a limit on what they can enter into the editbox
any ideas ???

So how do you know that all of the data from the edit control is not being transfered? Have you considered just using the edit control's GetWindowText() method instead? Used incorrectly, UpdateData() can hinder more than it helps.

"then when OnOK is called i just do an UpdateData to capture the text, but it doesnt capture all of it " -- before this all seem to be ok, but here ??
I also entered now in edit box about 4000 symbols, without marking in edit box ("Multiline", and such things), and it worked well ???
Try adding to your editbox CEdit value , and then get text with GetWindowText() function maybe it can help??
anyway i can't understand what kind of problem you have

CString is big enough and in fact a lot lot bigger than enough. It's got a 2 GB character limit.

A better question is how do you know that the CString isn't getting all of the text? The problem may not be the CString, but how you are viewing the result.

Thanks, i had realised this earlier when i was debugging
i didnt realise that not all of the strings contents were being displayed
when i watched that variable
i just assumed that the watch value was the whole value
thanks anyway

hehehe that's exactly where I was going. I've been stung by that one before too, unitl I realized what was going on.

Not sure if this is a VB question or not, but I'll post it here anyway.
I've written an activeX control which uses a mutex to protect a critical section part of my code, I use CreateMutex and OpenMutex to create/open the mutex, then waitForSingleObject to grab it, ReleaseMutex to release it.
If I stick this activeX control on a VB form, and create an .exe from the form. I can open as many of the exe's as I like and the mutex is only opened by one of the exe's at a time.
However when I put multiple ActiveX controls on the one form, create an exe from that. When I run this single exe, the multiple controls can open the mutex at the same time, and run the critical section code simultaneously. Is this beacuse all the controls are running from the same thread?
How can I get round this? I want my code protected but can I do this with having the controls on the same form?

You may not need to use a mutex. How about just jacketing the critical section part of your code with a static CCriticalSection?
