Hi ,
Im new to VC++...May i know what"s the difference b/w MFC and vc++ and where to start with...
im planning to start with Programming windows with MFC (Jeff procise)..
Please correct me if im wrong...

Visual C++ may refer to the Microsoft C++ compiler, or even the IDE. You can think of it as C++ on windows. MFC is a c++ framework written around Windows APIs to make life easier. Wikipedia has separete entries for Visual C++[^] and MFC[^]. Give them a read.

That would be a very good start if you are good at object oriented programming, specifically C++. (But legend says that you must start off with Win API and then move forward to MFC, not that it is a rule though)
Good luck with your learning. It must be fun.

AVI compression looks like a viable option? There are video compression libraries on the internet (some with source code and samples).

solve the following system:
2x1-x2=1
-xi+2xi+1=0, i=1,2,.....,n-2.
-xn-1+2xn=1.
Using a)thomas method,
b) Jacobi method,
c) SOR scheme (use w=1 (Gauss-Seidel), w=1.1, w=1.2, w=1.3, w=1.4, w=1.5).
Use intial approximation x^(0) e=10^-6. Limit the maximum number of iteration to N=500. Display the output in the following form:
Number of iteration for convergence:?
Solution:
x1=
x2=

x20=

Hi
If this is your problem:
2x1-x2=1 ...................[1]
-xi+2xi+1=0, i=1,2,.....,n-2. .....[2]
-xn-1+2xn=1 ......................[3]
solution:
from [1] you get:
x(2)= 2*x(1)-1
from [3] you get:
x(n-1) = 2*x(n) -1
from [2] you get:
n= ? : rem n value should be set
for j=1 to 50
rem 50 is max iterations set to.
for i=1 to n-2
if i=2 then
x(2)= 2*x(1)-1
end if
x(i)= 2*x(i+1)
next i
x(n-1) = 2*x(n) -1
next j
Remark: I hope I understood your problem, since the solution
correctness depends on that too.
If your your problem is not stated correctly, that
belongs to you.
I hope that I helped, if you need more let me know.

Alright, I'm trying to have my program, which was writting in C++ using Dev-Cpp 4.9.9.2, open a separate program.
I know this can be achieved throw the use of system() but I can't seem to get it to work right, I'm currently using the command line:
system("c:\\Program Files\\Internet Explorer\\iexplorer.exe"); I get the error "'c:\Program' is not recognized as an internal or external command, operable program or batch file."
|
|
|
|
|
- It's just a command line, as passed to CMD, so put double quotes around the path as it contains spaces:
system("\"c:\\Program Files\\Internet Explorer\\iexplorer.exe\"");
- Isn't it iexplore.exe, not iexplorer.exe?

Thanks again Stuart really appreciating all the help you're giving me. That one worked perfect on the first try. I didn't know anything about double quotes until a little bit before i posted this issue. I looked up other examples on google and when I tried it with the double quotes before it told me the same issue. But having just tested it with the line still saying iexplorer instead of iexplore it gave the error again, so it looks like that was my issue.. really need to stop doing this at 2 am..

|

The message you showed, saying that 'c:\Program' wasn't recognised, is a giveaway that you're having issues with spaces in the command-line. If you see it in the future, that's what your issue will be...

In my VC++ 8.0 project I got the following errors:
1>d:\development\glestold\source\shared_lib\sources\graphics\interpolation.cpp(19) : fatal error C1083: Cannot open include file: 'windef.h': No such file or directory
1>d:\development\glestold\source\shared_lib\include\platform\sdl\sdl_opengl.h(32) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory
I searched and found those files in the PlatformSDK folder i.e
C:\Program Files\Microsoft Platform SDK\Include folder.
I included this and the corresponding lib path in the project settings.
Now I get a punch of errors in winnt.h file in which I didn't do any modifications(system file).

trying doing "#include<windows>" and "#include<windef>"
When I first started using Microsoft Visual Studio 2008 I kept having issues in regards to using the .h or not. Online tutorials and some books would tell me that most if not all include files had to have the .h but my compiler would only work when they didn't. So, it might work, it might not. </windef></windows>

I changed the #include statements as you said: But it's not working. What else can be done? I've installed the Microsoft Platform SDK. Is it the suitable one for Visual C++ 2005. If not can u tell me the correct version?

Hello,
please help me to write a function rotate that will rotate the rectangle 45 degrees each time button is pressed
let say that rectangle values are as follows
rectangle[0].x=250.0;
rectangle[0].y=100.0;
rectangle[1].x=550.0;
rectangle[1].y=100.0;
rectangle[2].x=550.0;
rectangle[2].y=300.0;
rectangle[3].x=250.0;
rectangle[3].y=300.0;
i know that it should be something like
H2 = H·cosθ + W·sinθ
W2 = H·sinθ + W·cosθ
where H2 is the height of the rotated rectangles and W2 is the width.
i need an assistance in writing this function.. please help
|

1. Decide what point is to be the centre of rotation. Let's call it O, with co-ordinates (Xo, Yo).
2. Rotate each point of the rectangle, Pi, with co-ordinates (Xi, Yi), around O, producing a new point, Pi', with co-ordinates (Xi', Yi'). You do this using the following two identities:
Xi' = (Xi-Xo)cosθ - (Yi-Yo)sinθ
Yi' = (Xi-Xo)sinθ + (Yi-Yo)cosθ
You now have your rotated rectangle!

umm what i have in my code is something like:
px = (rectwidth/2); py = (rectheight/2);
so i assume that they represent my center through which i want to rotate my rectangle (px, py)
however, i am not sure how to represent all of the point of the rect to be Xi Yi
considering that my rectangle representaion is as mentioned in the previous post with co-ordinates of
(250, 100) is rectangle[0]
(550, 100) is rectangle[1]
(550, 300) is rectangle[2]
(250, 300) is rectangle[3]
i am new to C++ so i am having trouble seeing how your equasion can be programmed. i do understand the equasions u've provided though.
Please any suggestions on the programming?
like:
void rotate (float angle)
{
? = (? - px)cos(angle) - (? - py)sin(angle);
? = (? - px)sin(angle) + (? - py)cos(angle);
}
not sure what should be in there.

OK - for 'Pi', read 'rectangle[i]', for i in the range 0 to 3.
So, for rectangle, assuming you're transforming rectangle into a new rectangle, rectangleNew:
void rotate (float angle)
{
rectangleNew[0].x = (rectangle[0].x - px) * cos(angle) - (rectangle[0].y - py) * sin(angle);
rectangleNew[0].y = (rectangle[0].x - px) * sin(angle) + (rectangle[0].y - py) * cos(angle);
rectangleNew[1].x = (rectangle[1].x - px) * cos(angle) - (rectangle[1].y - py) * sin(angle);
rectangleNew[1].y = (rectangle[1].x - px) * sin(angle) + (rectangle[1].y - py) * cos(angle);
rectangleNew[2].x = (rectangle[2].x - px) * cos(angle) - (rectangle[2].y - py) * sin(angle);
rectangleNew[2].y = (rectangle[2].x - px) * sin(angle) + (rectangle[2].y - py) * cos(angle);
rectangleNew[3].x = (rectangle[3].x - px) * cos(angle) - (rectangle[3].y - py) * sin(angle);
rectangleNew[3].y = (rectangle[3].x - px) * sin(angle) + (rectangle[3].y - py) * cos(angle);
}
Don't try and rotate points in-place...

If you want to see a VERY well written (I'm biased) article which has a lot of transformation work with matrices, look at:

I've been trying to use the Synthesis Toolkit (Found here, for those unfamiliar: http://ccrma.stanford.edu/software/stk/ ) The instructions to use it on the site seem rather vague, at best. I've downloaded DirectX 9, and added a slew of libraries to link with, and now I have some unresolved external symbols. I'm not sure how to go about tackling these messages, and am not sure what could be causing it, or what could be missing. It looks to me like a missing function in RtApiDs, but I don't know where this class is. If anyone has any experience setting up the STK for Visual Studio 2005, guidance would be greatly appreciated.
These are the four error messages I am getting:
1>RtAudio.obj : error LNK2019: unresolved external symbol _DirectSoundCaptureEnumerateA@8 referenced in function "public: virtual unsigned int __thiscall RtApiDs::getDefaultInputDevice(void)" (?getDefaultInputDevice@RtApiDs@@UAEIXZ)

And here is the list of libraries I am linking with:
odbc32.lib

dsound.lib
dxguid.lib
winmm.lib
Wsock32.lib

*Edit: Edited the title of the post because this looks as if it is a DirectSound issue.

Hi, is it possible to get process IDs for the current user only... or alternatively from a process ID (PID) get the owner?
I tried using CreateToolhelp32Snapshot, this gives back processes from all users. When two different users have started an executable "test.exe" at the same time I'd like to find the PID of the "test.exe" from the current user.
Thanks!
