So you're a .net beginner but really just a programming beginner yes?

That statement tends to indicate that you don't have basic fundamental skills of software development. It might be possible to use internet forums to struggle through to a solution but I suggest that approach is suboptimal. I believe that using some books or taking some courses that target beginner fundamentals would streamline your learning curve as well as increase the quality of the software products you are responsible for producing.

The only objective of my project is to find a way to compensate for the mechanical lost on the Z axis. Only 2 people with even less skills for programming will be using this .net file.
I have about 100 hours (at about 12 hours/week) to try to come up with something useful, but the program doesn't need to be "professional". I just needed some tips as to how this could be accomplished.
The loop algorithm would simply be:
do
{
Get Xposition
Get Yposition
Z=F(X,Y)
Move Piezo(Z)
}while THREAD unfinished
It's JUST the part of activating this loop WHILE the thread is being accomplished that eludes me. But anyway, thanks for your "help", I will try some other forum (Not that I haven't read any files or books to try to get an answer...)

You have two (crude) options:
(1) Go multithreading
(2) Insert the Z correction code inside the main thread (of course you lose the loop, the correction will be sparse in the main thread).
From design grounds, probably point 1 is more attractive (you have two logical separated paths for action code and Z compensation one), but for practical reasons maybe the second approach will be (and only you, having system knowledge, know if it will be) really more effective (i.e. ad hoc compensation based on current action).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

And oh yes; I do have programming experience, having completed 2 courses: c++ and object-oriented programming. However, I AM NOT a computer engineering student, but a mechanical engineering student with a major in mechatronics. However, this project, as it was suppose to be mechatronics oriented, turned out to be more of a programming challenge, and I intend to see it through. That is, as far as I know, ALSO a good way to learn.
I hit a wall, I need help, and taking a course is not an option for THIS particular task. Can SOMEONE point me to a USEFUL source?

How disturbing it is when you come out of your way to offer some help and a dunce gives you a 1 vote because you asked him to read a book.

A 1 vote? I didn't vote, and I appreciate every bit of help I can get!

I'm sorry, in that case. I've seen some people doing that here, so I guessed a hazard.

I didnt work with device drivers yet..can anybody help me
thanks in advance..

You need documentation from the driver/device that explains the data/communications/protocol whatever. Other than that you use CreateFile/ReadFile/WriteFile as the basis of connecting and communicating.

Don't forget DeviceIoControl[^]. In many cases this is used more than ReadFile and WriteFile when communicating with device drivers.

I ahev an application that spits data continuously to an edit control in a dialog based MFC app. I cannot seem to get the edit control to keep scrolling with the data as the data reaches the end of the visible box area. Is there a better control or does the edit control have a way to automatically keep up with the data being sent to it so that you do not have to manually use the scroll bar to get to the last piece of data on the screen?

Is your data that comes in line-delimited? If so, use a listbox. Otherwise, you'll need to add the incoming data to the end of the edit control using SetSel() and ReplaceSel(), or use LineScroll().

Hey everybody!
I'm a bit new in unmanaged c++, let alone ADO, so its a bit of a newbie question...
I'm trying to get the signatures of the stored procedures in my database.
Thanks!

Hello,
I'm not a pc expert. I have a Sony Vaio VGN-AR31E working with Windows Vista and I just bought a Video software called Ulead Video Studio 11.5 software. I tried to install it but for that I need to install Microsoft Visual C++ 2005 Redistributable. I tried several times to install it (version 2005 SP1 or version 2008) but i always have the same error message : "Error 1935. An error occured during the installation of assembly 'Microsoft.VC90.ATL, version="9.0.21022.8",publicKeyToken="1fc8b3b9a1e18e3b", processorArchitecture="x86", type="win32". Please refer to Help and Support for more information. Hresult: 0x800736B3.
I feel completely lost and have no idea of what to do?... could you help me and send me any help by e-mail (jhaustraete@gmail.com). Thnak you very much!

I'm developing a game as a win32 project.
I now need to add some simple windows forms to the game. When I try to do that, VS asks me
"you are adding a CLR component to a native project. Your project will be converted to have Common Language Runtime support. Do you wish to continue?"
What should I consider (portability, efficiency) before choosing yes?

You know about the difference between Windows Dialogs and .Net-Forms, do you?
You want to write a game using C++, right?
And you are positively sure that you want to add a .NET-Form to that game?
If you answer any of above questions with "No." of "Hmm - maybe..." or even "Huh?", you need to rethink what you really want to do.
If you answered all questions with "Yes!", you will need to have your project converted to Managed C++. And that is what the dialog offers.
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Thank you very much.
I think I know the difference. I guess it's very hard to acheive functionalities of a .NET form with a Windows Dialog.
And I need about ten different designed forms, some are pop-ups, some are complicated forms.
I do write a game using c++.
I'm not sure about adding .NET component. I want to because it will make like a lot easier.
There is ofcourse the question of portability - I'm demanding my players to have .NET 2.
The question is how terrible is that ?
out of the users that have directX9, how many have .NET 2 ?
Is it really a big deal to install it (.NET) during installation ?
efficiency considerations ?

What is it you want to achieve? We here are happy to help you.
Hanan888 wrote: I'm not sure about adding .NET component.
If you are adding .NT anyway, why do you want C++ in the first place? You seem to know .Net already.
You could use .NET as your main target (C#, VB.NET, IronPython, Boo...whatever) and code things where you have to have access to Win32-routines using a C++/CLI to unmanaged C++ bridge.
Hanan888 wrote: Is it really a big deal to install it (.NET) during installation ?
No.
But AFAIK you are not allowed to ship the framework with your product.
The customer would have to get it directly from Microsoft.
But the time to install is about a quarter of an hour.
IIRC, Net 2.0 is limited to W2K and newer. You would exclude the Win95-based platforms. Probably not a real problem.
Hanan888 wrote: efficiency considerations ?
.NET, like Java, tends to eat a lot of memory.
The Quake engine was ported to managed C++ and ran fine. Only a little slower.

IMHO, just say 'no'. .NET is for business applications, not games.
You can make great GUIs without it - look at WTL, for instance.

Hello All
I am using MFC with OpenGL to code multimedia application, I am using SDI architecture, and I found that when I open any menu item and select it, windows sometimes don’t erase the menu area immediately, and it appears like a shadow over the OpenGL window, until I do any repaint action it disappears
It seems to me that it is windows issue, but I am not sure!

A-M-S-S wrote: It seems to me that it is windows issue
I would say the opposite  . Whenever windows need to refresh a window (like for example in your case because something went in front of it), it will send a WM_PAINT message to it. So it is up to you to repaint the window whenever you receive that message.
