Have you read up on DragAcceptFiles(), DragQueryFile(), and WM_DROPFILES?

Hello Sir/Mam,
I am working on Microsoft power point using Microsoft VC++ 2008 . I want to know ,when i create an instance of power point Application then no one can see the application or it should not be visible after activate a presentation.
When i use Setvisible(FALSE) function, there is exception occured.

Hi,
I am C++ newbie so.... I was trying to derive an Object from CString
Since Derived Classes can access protected members I tried to access
m_pchData
When I got an errors message that m_pchData was undefined I tried to
qualify it by using CString :: m_pchData
When I got the following error message
I dont get I am using CString in afx.H not CStringT in afxstr.h
Error 1 error C2039: 'm_pchData' : is not a member of 'ATL::CStringT<basetype,stringtraits>'

m_pchData doesn't exist in MFC for VS 2005 or 2008. In these, m_pszData is private, but you have helper functions to access it.

I understand but why does the compiler reference CStringT
When I used the CString object
|
|

CString is simply a typedef of CStringT. CStringT is derived from CSimpleString. This combination allows various encoding methods to be used with the same code. Thus you have CStringA (using char) and CStringW (using wchar_t) as basic types. In theory you could create even more types by using the templates and adding you own helper classes.

So ....CStringT is for regular excuse the term string char
as opposed to Unicode
The members of CString are really in AFX.H were Cstring is defined
|
|

|

No, CStringT is a template class that allows you to instantiate a string class that uses ANSI, UNICODE or whatever encoding scheme you want to try.
CString is a typedef of CStringT. The typedef for CString is NOT defined in afx.h. As far as I can tell, you are confusing VC++ 6.0 and VS 2005/2008.

You could be right thr AFX.H member where I found CString
Was in my Platfork SDK folder
Not in the VC folder (Part of Visual Studio SubDir)
Thankx

Do NOT use any MFC from a platform SDK. You shouldn't even be referencing such an outdated SDK in VS 2005/2008 since it will cause other frustrations. (I rarely use the Platform SDK and when I do, I always install it in a Virtual PC, clean out the dross and then copy the directories out and then only use it by specific reference in the a project file.)

Ok Im trying to start this problem off but i have no idea where to start off i was wondering if someone could break it down for me.
A voltage source supplies a load through a resistor. The
voltage source has a rating of 1000 volts and a power rating
of 10000 watts. The resistor is 5 ohms with a power ratings
of 118.975 watts. The resistance of the load may vary
randomly between 200 and 600 ohms. Using 100000 samples
calculate the I have to find the number of times the power rating of the resistor is exceeded,average power delivered by source, maximum power delivered by source,and the minimum power delivered by source

AFAIK VC++ stands for Visual C++, not for Voltage Computing++...

Hey dude! your question has nothing to do with programming. Take your question to appropriate forum before someone zaps you with 1000 volts rod. ![Jig | [Dance]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/jig.gif)

I have to do this using C++, so i think i have the appropriate forum

yes you could do it in C++. There is nothing that will prevent you. But your question does not have any slight hint of programming.
Heck, during my days of Electronics classes, we did it using paper and pencil. How is that for programming

Wow, paper and pencil...100000 samples...how long did your Electronics course take?

Having the sample count already specified implies this is a homework question, but I'll try to give as many hints as I can without ruining it for your learning...
1/ To start with, this isn't a C specific question, but there's nothing stopping you doing this in C. You could do it in fortran, c#; heck, I'd probably recommend using excel...
2/ Your initial problem is solving the equation on pen and paper.
(Yes, I know you have a thing that varies - remember your algebra)
volts = current * resistance
power = current * volts
current = volts / resistance.
I'd suggest excel to start with, or a simple MFC dialog application with a box you type in a user supplied resistance value, and then spit out the results you care about to test your equation.
4/ Now move on to the second part of the question, the varying resistor.
4a/ What is the probability curve? Even if you assume it's flat, you should document that assumption. Why is it varying? If it's a toddler playing with a knob, it may be a guaussing distribution. The point is that it's not specified, so you either have to ask, or at least spell out your assumption.
4b/ Look up Monte Carlo Simulation - I bet it's what you've been taught. Run your function 100000 times with a random number between 200 and 600 and pop the results into a huge table.
4c/ Whether you write them to a text file, and import that into excel, or add a pretty graphic control (we have them here on CP) is up to you.
Good luck,
Iain.
