Can you see if _MFC_VER has been defined?

Well, CString can be available for use where _MFC_VER is not defined as well!
For instance, you could use CString in a console project with no MFC support by just including atlstr.h You could better do this:
#ifdef __ATLSTR_H__
#endif

Well, CString is available even where __ATLSTR_H__!
Just write:
#include <cpallini_free_stringz.h>
#define CString stringz

Hi All,
The task which is given to me is that i have to show a cylinder in 3D.Then when i click on any part of the cylinder and drag the mouse i should be able to deform the cylinder and when i leave the mouse the object should be in the last deformed state.I am planning to use directx for this.
Any inputs from you will be very helpful for me.
Thanking you in Advance,
Regards,
Ashwath.

I'm guessing, based on your post that you have not done much Direct3D programming (otherwise, you'd know the answer). Can you display a just a cylinder (without any modification)? That would be the obvious starting point. Wireframe? Solid? Lighting? What version DirectX? You leave out alot of important details. You should initially query the capabilities of your graphics device. But, essentially, I think you will want to coordinate the output of a number of standard DirectX APIs: Direct Input (to respond to the mouse action), and, the display of the cylinder data. The way I'd do it would be to implement a cylinder Mesh (which is a standard DirectX object), and which gives you access to the Vertex Buffer and Index Buffer (and all the other data you'll need). The easiet method would be to implement a series of drawing calls using a progressive algorithm that deforms the Mesh by some simple metric. You would be writing data to the Vertex Buffer and then displaying the Mesh.
Also, there is a Graphics Forum here at CodeProject, where you'd probably get a better answer.

Hello all,
I developed a VC++ application. Basically I extract some data from the webcam, process it and give the results to a formular.
When I initiate the data processing, the GUI does not respond anymore. The data processing is still going on, because I can check with breakpoints that the analysis has not crash. But as the computer seems to be bussy on the data processing, I can not display it on the Windows.
I was considering using Threads, but I´m having some problems with the Threads provided by VC++, so I might move to pthread instead.
Does anyone have faced this problem before? Is there any recomendation or suggestion?
Thank you, and best regards,
Enrique

Which kind of problems are you having with windows threads? You don't need to switch to posix threads, windows threads are a proven technology

Hola Miguel, and thank you for answering
Basically, I´ve the following problems:
Following this manual:
http://support.microsoft.com/?scid=kb%3Ben-us%3B815805&x=13&y=8[^]
Everytime I try to switch to (/clr:oldSyntax), instead of just /clr, I´m getting so many errors with my application (like using public, private, etc :P).
Following this manual:
http://hemswell.lincoln.ac.uk/~slawson/napier/CO42018/labs/lab06.html[^]
The line that says:
hThreads[0] = CreateThread(NULL,0,MyThread,"T1",NULL,&iID[0]);
Drop me this error (translated from German to English):
error C3867: "OpenCVWin32::Form1::ExampleFunction": The function call is missing argument list. Use "& OpenCVWin32:: Form1:: ExampleFunction" to create a pointer to the member.
So I use the mentioned syntax. And then:
error C3374: Address of "OpenCVWin32:: Form1:: ExampleFunction" can only be adopted if a delegate instance is created.
So at this point I´m really blocked :S

I think you are mixing a managed C++ thread tutorial with your unmanaged code. You should look into CreateThread function parameters in MSDN help. Maybe you are passing something that does not conform to the function pointer that it expects in the third parameter.

Thank you Miguel,
So far the application seems to compile when I declare the threaded function as static, but I have some memory violations problem (could be solved by using Mutex?). I will read the documentation you suggested me, and try to post if I find a solution.
Cheers.

Nope, you've to fix your code.

hi:
MFC dialog-based application, how the real-time rendering curves, what parts to draw, how to ensure real-time?
Is mainly how to achieve real-time, actually read data from the serial port mapping curve, a bit like temperature monitoring software

Could you elaborate a bit your question ? What do you want to do ? What is this curve you want to draw ? And what do you mean by real-time exactly ?
|
|
|
|
|
Please clarify your question. Are you talking about Bezier curves? And what do you mean by real-time - animation?

It still not really a lot of information but I guess you want to display some kind of graph. In that sense, you can take a look at my sig, there's a link to a chart control that I developped and which is quite efficient (well, it was designed to be efficient because it had to plot some data at high rate on a pocket PC).

Just try a Google search and you will probably find many titles, although I don't know how many free ones there are. If you need help with actual problems when you start writing code then you can always post questions here.
