Hi, I'm a begginer in this programming stuff, and I learn visual C++ from the book "teach yourself visual c++ in 21 days". anyway I am on the 6th day now and I have a small problem with the menu code. here is the listing:
1.CMenu *m_lMenu;
2.CPoint m_pPoint;
3.m_pPoint = point;
4.ClientToScreen(&m_pPoint);
5.m_lMenu - GetMenu();
6.m_lMenu = m_lMenu->GetSubMenu(0);
7.m_lMenu->TrackPopupMenu(TPM_CENTERALIGN + TPM_LEFTBUTTON, m_pPoint.x, m_pPoint.y, this, NULL);
now when I compile my project ( ofcourse there is other code which works just fine), compiler gives me 2 warnings:
D:\C\projects\menus\menusDlg.cpp(203) : warning C4552: '>>' : operator has no effect; expected operator with side-effect
D:\C\projects\menus\menusDlg.cpp(204) : warning C4700: local variable 'm_lMenu' used without having been initialized
this code is copied from the book so if there is error then the error is in th book.
So my question is what is the problem? my guess is that there is something wrong with line 5 (m_lMenu - GetMenu()) make's no sense right? or is the problem in something other?
I tried even with -> and .

Looks like line 5 should have used the = operator instead.

This text is your translation from %LANGUAGE% into english?
Do you have a compiler error number (four digits with a 'C' or 'L' prefixed)?

Just because you have a solution to the problem, and it may be a little embarassing for you (we've all been there - including me just a few days ag0), please don't delete the question.
When people look at the forums, they'll just see answer's with no questions - and that's just confusing and rude.

Good comment, however there is no simple way to delete whole thread which in this case would be prefered.
My error was that I ovelooked my own error catching message and thread process was timing out on me. Thus I did not see the entry point.
I am not sure if that would be of any benefit to anybody.

Well, deleting the whole thread would be harsh on those people who kindly helped you - a little public visibility of helpers keeps them helping, I think.
I do understand where you're coming from though - I recently posted a dumb question, and kinda wished I could go back in time too....

I have converted my exisiting vc6 project to vc8 i.e. visual studio 2005. Now i have created the exe and try to execute that on other pc where VS 2005 is not installed. I tried with linking MFC dlls statically even that is also not working.
Following error occurs when i execute the exe
"The application failed to initialize properly (0xc0150002). Click on OK to terminate the application."
Please help.

You are not trying to deploy a debug build, are you (or using any DLLs that are debug versions themselves)?
Just because you did a static MFC link does not mean that your application will not have any other DLL dependencies. Depends on what else you are using in your project.
Peace!

actually execuatble compiled with VC8, are also using manifest file to execute. which doesn't present in new computers.. you just download and execute vcredist.exe (URL given by Mr. David Crow)

So, I need to validate that a workstation exists on a local area network
I can do so in a few ways, like NetServerGetInfo or WNetGetResourceInformation
The annoying thing is, these functions hang for 30 seconds or so when passed
a workstation name that does not exist, example "\\notThere"
I thought of using some of the picg samples, but they require UDP protocol, which I cant depend on.
Does anyone know of a fast way to see if there is such a machine on the network?

Is IsDestinationReachable("\\\\notThere", NULL) of any help?

Yes that is better - about a 3 second wait for a non machine, versus about 30 seconds if GetFileAttributes() is called on a bad share.
Thanks for the tip.

Before anyone can provide an intelligent answer, do you need to know of a system (any system) is running at the IP address that the workstation name you provide resolves to, or do you need to make sure that a real Windows system is there?
If the former, something like a naive ping or routing tests will work. If the latter, you may be stuck with the functions you are using now. You could always throw up a "Please Wait" dialog while you are doing the test - like if you need to validate something against a license server...

We find illegal copies of our software in several countries.
Currently we hope a new developped software can be installed only on buyer's computer. In other words, the software only can be installed on buyer's windows OS.
To do so, I need to get Unique Windows ID, and software is installed by checking the ID - my plan is: buyer sends the ID to us before we submit software to him.
I posted a post before which asks for Windows CD-key, but repliers said it is impossible.
Do u know any idea to get Unique Windows ID to help me?
thx.

Several copy protection schemes resort to using the network adapters MAK.
I dont think you can get the windows code.

Welcome to the club! 
What you can do, as others have done, is not use the Windows registration key, but use other things that are system specific. Here is a list of a few of them, in order of increasing fragility (i.e. likelihood of changing):
o CPUID value (Google for the CPUID instruction)
o Motherboard/BIOS ID
o Number of IDE/SATA controllers
o Geometries of physical drives (not partitions or drive letter, and be sure to allow for additional drives to be added)
o On-board devices (# of COM and Parallel ports)
o NIC address(s)
o Computer Name
Not all of the items are easy to get, mind you, and ones that are easy to get like drive letters, computer name, OS version/patch level, etc. are more likely to change, and remember that it is a serious PAIN IN THE ASS to have to contact a software vendor to get a new key each time you upgrade your memory or drives.
Be prepared for more users to contact you about system-level changes invalidating their system-locked installation.
Peace!

Are there any functions to round the decimal value to its nearest decimal.
For eg:
1. float fVal = 5.26 The final result should be fVal = 5.30
2. float fVal = 5.23 The final result should be fVal = 5.20
using ceil it gives 6 and using floor it gives 5; but i m looking for nearest decimal.
Answers are appreciated.
