Well, I'm sure you know this but I would suggest buying a beginners book and going through that. They normally explain the Development Environment as well as teach you some c++ and even object oriented programming.
I started with this book: "Microsoft Visual C++ 5: No Experience Required"
- by Steven Holzner.
This is a basic book with examples. Serves to show you how things are done in Visual C++ and what can be done. Not the best book, but simple enough.
I don't know what to suggest for .Net as I have not bought any books myself. And am still working on Visual C++ 6.0.
Of course if you haven't done any coding then you will have to buy a book on programming in general.
Best of luck

I drived a class from CObject;all like this;
class CPerson :public CObject
{
public:
CPerson();
CPerson(CPerson &person);

CString m_strName;
};
CPerson::CPerson()
{
m_strNmae=_T("");
}
CPerson::CPerson(CPerson &person)
{
m_strName=person.m_strName;
}
CPerson &CPerson::operator =(CPerson &person)
{
m_strName=person.m_strName;
return *this;
}
but erro happed in compling ;the message is:
d:\microsoft visual studio\vc98\mfc\include\afxtempl.h(255) : error C2558: class 'CPerson' : no copy constructor available

Error executing cl.exe.
who can tel me where is the erros!
I am Made!

A copy constructor is defined to get a const reference, so you have to modify the param list of your copy constructor and your operator =. It should look like (const CPerson& person).

Not sure if this is the only error, but you've written m_strNmae instead of m_strName in your constructor

Your operator= is defined in .h file incorrectly.
CPerson& CPerson::operator=(CPerson person) ;
It should really be:
CPerson& CPerson::operator=(const CPerson& person) ;
Also if you define an operator= you should also define a copy constructor
CPerson(const CPerson& other) ;
CPerson::CPerson(const CPerson& other)
{
// copy across member variables
}

Hi,
I'm writing my first app in VC++6, what I want to do is have one parent window which contains a number of child windows with grids in them to display data. Each grid must be independant (i.e. they are not just different views of the same data, but contain totally independent sets of data.) The entire project must then be saved, i.e. all the data in all the grids stored in a single file.
This suggested to me that I should not be creating multiple views, so I am currently creating a new dialog whenever the user clicks a button on the toolbar, and keeping track of them all using a CTypedPtrList in the document. I created the app using AppWizard, as an SDI app with CFormView as the view class.
Is this the correct / best way to accomplish what I want? Or should I be doing something else? If this is not the best way, an explanation of the advantages/disadvantages would be very much appreciated.
Cheers,
Jonathan.

Hi,
I'm sorry that this is not a VC++ problem. But i really want to hear some experience from you in this this message board.
I have a new Pioneer CDRW/DVDRW driver (newly published DVR-A04-J). And I have installed some related softwares (Drag and Drop CD, DVDit! SE, MyDVD). Now when i uninstall all of above softwares, the problem occured: The driver cannot be displayed by the exploer. I have try
many methods for deal with this, but i am failured. I used Windows 2000 professional. Is there a method for finding my cd-rom? or i must be re-install the windows 2000?
Thanks in advance!

Everytime I open Visual C++ dev studio I get a message box with this remark. Two questions:
1.: What the hell is he talking about.
2.: How to get rid of this annoying thing?
thx in advance...

He is talking about windows of the ressource editor (dialogs, bitmaps, icons and so on). Because processing the ressource script is somewhat time consuming, he does not reopen this windows at project open time.

Just ignore it, it's really nothing you need to care about. Or close all ressource windows before exiting VisualStuido

thx for your reply, Daniel
One thing: I really HATE popup windows with stuff I want nothing to do with. Believe me, I am not a dumb.
But... pls..
You sayd: 'Or close all ressource windows before exiting Visual Studio'
Problem: Whatever 'window' I close before exiting VS, this annoying popup msgbox greets me again the next time.
I want to get RID of it...
Hope you will read this, because a lot of posting is going on now here on CP.

Hm... I always believed it has to do with resource windows.
Just checked it again. It seems to have something to do with the WizardBar. MS calls it a bug. Maybe it helps if you just remove the WizardBar. This knowlegde base article explains the details.

Hello,
I am writing a dialog based application in VC++ 6.0
I was wondering if there is a way to detect if a user has chosen to display Large Icons or Large font on his computer using the desktop properties. I will appreciate any input on this. Thanks !!
Sincerely,
Anjum.

You can detect the font size use the following:
CDC ScreenDC;
ScreenDC.CreateIC(_T("DISPLAY"), NULL, NULL, NULL);
int nLogDPIX = ScreenDC.GetDeviceCaps(LOGPIXELSX),
nLogDPIY = ScreenDC.GetDeviceCaps(LOGPIXELSY);
ScreenDC.DeleteDC();
if(nLogDPIX == 120 && nLogDPIY == 120) { // 120 DPI, Large Fonts
}
else { // 96 DPI, Small Fonts
}

Yet Another List Control Question
i'm doing a subitem edit on a report-style list control. when the user clicks on a subitem, i put an edit control on top of the list control and the user deposits (types) his junk.
the problem is that the list control holds onto the mouse - you can't mouse-select anything in the edit control. so, i came up with two choices:
1. do a SetCapture/ReleaseCapture thing for the edit control. SetCapture when editing starts, then Release when it loses focus or the user hits Enter. i think this is overkill.
2. disable the list control while the edit control is up. this is ugly, since the list control goes gray.
so, my questions are:
1. if i do #2, is there a good way to control the disabled appearance (maybe just the background color?) or the list control, without doing an owner drawn control?
2. is there another way to make this work?
this is on an Explorer context menu extension, so i don't want to use a full-blown grid control.

This is not an answer to your question. But I am amazed at your ability to create all kinds of nifty custom controls. That really is your speciality.
I must say that of all the custom control stuff on CP yours is the best in my opinion [though I am sorta biased by the fact that I don't think much of those fancy buttons and menus]. I always feel that having a multi colored tooltip or a super-fancy button isn't as useful as having a control that actually does sosme stuff. Like a font selectiopn combo for example which is a lot lot more useful than say a combo box that looks like it walked out of cartoon network.

Chris, it's late, so i may have read this totally wrong, but how about just doing a ReleaseCapture() on the list control prior to displaying the edit control? I'm assuming you're doing this in response to NM_CLICK and not LVN_BEGINLABELEDIT to make it obvious that the cell is editable (not requiring the user to double-click).
Another possible solution, one that i've used and works very nicely (although it takes a bit more effort) is not to wait for the click at all, but instead to float the edit control as soon as the user moves the mouse cursor over the cell. This lets the edit control behave exactly as it would be expected to, without any subclassing.

how does this handle mouse selection of text in the edit control?
i think if you have full-row select enabled, the list control eats all the mouse clicks somehow.
