Hello Sirs
Is it possible to convert FFMEPG on Visual Studio ?
thanks

 Failure is Success If we learn from it!!

No it is not possible. See here[^] and here[^].

RASDIALPARAMS lpRasDialParams;<br />
ZeroMemory(&lpRasDialParams,sizeof(lpRasDialParams));<br />
wcscpy(lpRasDialParams.szEntryName, TEXT("我的连接"));<br />
lpRasDialParams.dwSize = sizeof(lpRasDialParams);<br />
BOOL lpBool = TRUE;<br />
DWORD dwReturn = 0;<br />
<br />
dwReturn = ::RasGetEntryDialParams(NULL, &lpRasDialParams, &lpBool);
dwRetrun value is 1168 ? what is this?

Try looking at the documentation for the function[^]. That points you at either the RAS specific errors or winerror.h. In winerror.h, you'll find this:
#define ERROR_NOT_FOUND 1168L
which I suspect means your entry name is unknown.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

yes, i seee it.
but entry name is right, the name is same of ras connect name

I'm using a long long variable with swprintf, however swprintf is unable to understand long long and returning zero.
wchar_t[20];
long long var = 500000;
swprintf(t, L"%i", var);
MessageBox(NULL, t, L"Output", NULL);
tried %i and %d
any advice for work fix solution or a work around! i would be very thankful.

try %lld, that's what most C runtimes use, I don't see it in the MS doco, but it might just work...

Not portable, "I64" formats a _int64, while "ll" formats a long long, which is AT LEAST 64 bits long. Haven't yet met a platform where they differ though 
|
|
|
|
|
OP said nothing about "portable"
|
|
|
|
|
See the MSDN reference here[^] for details of format specifiers. Your format string uses "%i" which is for normal integer.
It's time for a new signature.

How do you format numbers with commas?
10
100
1,000
10,000
100,000
1,000,000
10,000,000
100,000,000
1,000,000,000
I found the context for doing that somewhere before, but I'm unable to find anywhere!

Hi, I'm a student and now I'm working on a project in computer vision field. I need to detect the changes between two images (captured at different times, at the same position ), and the problems are noises and illumination variations in these images. I've read many paper with complex algorithms to solve these problems, but it's very difficult to implement them in programming language (mine is C++). Could you suggest me how to solve these problem, or point me to an open source program which does this task ?
Thanks and best regards !

Here is a more logic thinking solution than actual guidance.
I'm sure you know char table[x][y], I believe you can use it with the Bitmap data type. I don't know the relevant declaration for it. You create a table for the first image and a second table containing the second image. You can then select which to use as reference and then calculate based on pixel [1][1] for the second picture based on the difference for the reference picture. Hope that helped!
If you can share those papers, I have interest to dip my hands on something similar.

There will be slight changes in the images even when the target object hasn't changed. The key problem is determining if the changes are enough to conclude the target object has changed.
The first step is to obtain sample data. Capture repeated images of the unchanged object (under different conditions, e.g. day/night). Then capture images of the MINIMUM change in the target object you want to detect.
The next step is to analyze the variation among the images of the unchanged object, and the differences between the images of the changed/unchanged object.
In the easiest case, you'll find a simple threshold that will distinguish between the changed and unchanged cases. It's harder if the noise/illumination differences among the unchanged images exceed the differences between changed/unchanged objects. In this case, you'll need a more complex algorithm.
Two things to look at: 1. Total number of pixels that have changed, and 2. Total number of pixels that have changed by more than a given threshold.

So, Trying to make a 5 card draw poker game using C, and I've come across a hurdle. The following code is randomly choosing cards correctly, but when I try to change them from their deck number to their card, they all come out as the same card. Not sure what is happening, but if you run the program, I put cout statements in to show how the numbers are random.

Sorry for it being so long. First programming class, so I can only use what I know.
The includes didn't copy correctly, so here they are.
#include<iostream>
#include<string>
#include<ctime>
#include<cstdlib>
#include <stdlib.h>

Hi,
probably lots of problems in your code; I didn't look at it in any detail as there is a lot of it and it is badly formatted. Next time use PRE tags so it gets to preserve its original formatting and indentation, and gets shown in a non-proportional font, with syntax coloring.
if(cardNum9 == 8 || 21 || 34 || 47) is not what you want; you mean
if(cardNum9 == 8 || cardNum9 == 21 || cardNum9 == 34 || cardNum9 == 47)
which you probably could write as just if((cardNum9 % 13) == 8)
Whay you wrote is ORing all the numbers, treating them as booleans, hence the result is always 1 (unless all your numbers were 0).
Strong suggestion: if you are familiar with arrays, start using them right now. You can do what you have with one fifth of the code you have now, and less code means less trouble and fewer bugs. You will waste a lot of time by not using arrays!
and why is it %51 and not %52???????????????

Thanks for the quick reply, Luc.
I'll plug the new way of doing the numbers into my code in a little while, hopefully they will work, but my wrists are starting to cramp from all the playing in the code I've been doing.
The class I am in doesn't start array's until next week, so that's why I haven't used any yet, but I do plan to use them. I just wanted to get a jump-start on my final project and see what I could do with what I know.
And I have it as %51+1 instead of %52, because doesn't %52 give you all the numbers from 0-52? I don't need 0 so by adding the +1 to %51, I make it 1-52.

as %N returns the remainder after division by N, what do you think the largest value of %N could be?
without arrays, make sure to consider using a lot of modulo operators! I already gave you an example.

just a note.
the % operator has a lower precedence than the + operator. so you code is really doing this: rand() % 52 . that is, the addition (51 + 1) happens before the %.
this might be closer to what you want: (rand() % 51) + 1
don't know if it will solve your problem, tho.
