Can anyone explain how to use the CWnd::HtmlHelp(,) function? I'm using VS2008 and programming in MFC so I'd like to use the CWnd version rather than the API version. I've search MSDN and they show plenty of examples for the API version , but NONE for the CWnd version. Or at least I haven't found any. Can someone explain, by example the CWnd version's usage,Please.

You would use it like any other class method. Do you have a CWnd object?

Can you more explain about your program,please?

then what will be the following is true for that instance
1)all instances of the parent class will reference one variable and each instance of the child class
would reference its own separate variable
2)all instances of the parent class would reference one variable and all instance of the child class would reference another variable.
3)All instance of the parent and the child classes would reference the same variable.
4)Each instance of the parent and the child classes would reference its own separate variable.
5)None of the above
I want to know answer with some detail, if anybody could have .
Thanks in advance

Sometimes a little test is better than a thousand words:
(assuming 'parent' is base class and 'child' is derived one)
#include <iostream>
using namespace std;
class A
{
public:
static int alpha;
};
class AA: public A
{
public:
static int alpha;
};
int A::alpha = 1;
int AA::alpha = 5;
void main()
{
int i;
const int N=5;
A a[N];
AA aa[N];
for (i=0; i<n;> {
cout << "a[" << i << "].alpha = " << a[i].alpha << endl;
cout << "aa[" << i << "].alpha = " << aa[i].alpha << endl;
}
}
</iostream>
The output is:
a[0].alpha = 1
aa[0].alpha = 5
a[1].alpha = 1
aa[1].alpha = 5
a[2].alpha = 1
aa[2].alpha = 5
a[3].alpha = 1
aa[3].alpha = 5
a[4].alpha = 1
aa[4].alpha = 5
Personally, I'll bet on point (2).

Yes, since about XVII century.

Hello,
I am making a GUI on Visual Studio's (2005) Windows Form Application. I have set the radio buttons to a default value. But, I want to give the user the choice to choose another radio button. But since I have set the value of "Checked" in the event handler of the radio button, right now the default value is the only value that can be chosen (so its fixed). How do I make this changeable?
Thank you in advance,
jazz24

I'm not all that sure what you are asking.
If you have individual options, which can be on or off independently of each other, then you should be using checkboxes, not radio buttons.
If you have a choice of (eg) three things, only one of which can be selected, radio buttons are good.
They need to be one after each other in the tab order, the first one needs the group bit selected, and all after the first need it deselected.
I would also strongly recommend that the ID numbers are in the same order as the radio buttons.
Then you can use
CheckRadioButton (int nIDFirst, int nIDLast, int nIDSelect);
to programmatically select a radio button, and IsDlgButtonChecked to check whether a radio button is checked or not.
Or DDX_Radio (...) in your CDialog::DoDataExchange (...) function for MFC dialogs.

My VC6.0 (win 2000 server) stopped responding to F1 and won’t do MSDN search either.
I get an hour glass and File Manager indicates that application is not responding.
I have reinstalled VC 6.0, with SP 6 and reinstalled my MSDN. Any other suggestions?
I am ready to do new install from scratch.
Please, no Vista / VS 200x “upgrades” suggestions , not an option!
Thanks for reading.

I am trying to create a dll from c++ to be used as a plugin for iTunes. Unfortunately I cannot find any documentation on this. The plugin I am trying to make will be pulling information from iTunes while running and display it in the taskbar as an icon with bubble notifications when the song changes, showing song title etc. Does anyone have any code from plugins they have made in the past? I am very new to this haha.
Thank you

How can you create a freestanding .exe that does not require the CLR using VS2008. The program is actually ANSI C code, no C++ except for // COMMENTARY.

you mean a standalone ?
just statically link the required libraries in your linker settings...

In the project settings/Configuration Properties/General, set Common Language Runtime support to
No Common Language Runtime support.

Thank you all for the help.
I did not exactly state the true situation, and that was causing me some problems. The project actually linked in another library (also ANSI C only), but the library was build with /MD and this caused multi-defined errors when I tried to use /MT for the base project. I did have the source of the library (fortunately) so I rebuilt it using /MT also, and then the base project compiled correctly. Tested the .EXE on this machine (without VS installed) and it works correctly.

I have this dialog:
<br />
MYAPP DIALOG 10, 19, 158, 104<br />
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU<br />
...<br />
BEGIN<br />
...<br />
RADIOBUTTON "1&50%", IDD_Zoom150RB, 16, 10, 32, 10, WS_GROUP | WS_TABSTOP<br />
...<br />
RADIOBUTTON " ", IDD_ZoomSpinRB, 62, 38, 12, 10, WS_TABSTOP<br />
EDITTEXT IDD_ZoomSpinEF, 76, 36, 36, 14, WS_GROUP<br />
...<br />
END<br />
The contents within IDD_ZoomSpinEF editbox, needs to update the IDD_ZoomSpinRB label.
The editbox isn’t associated with the ratio button, thus when the ratio button is selected nothing is read.
How can I associate the editbox with the ratio button?

You can't "associate" them, and have it automatically work.
What you can do is write a EN_CHANGE handler for the edit box, then use SetDlgItemText (ZoomSpinRB, ...) to set the text for the radio button.
I'd be tempted to skip this step though - make the radio button text be blank, and just put the edit box where the radio text would have been. Then when they click on the custom option radio button, read the edit box and use that percentage for whatever you want it for.

Thank you! Your answer helped me much. I used EN_CHANGE notify and SetDlgItemText().

Hi there,
I working in VC 6.0, in which I need to polulate the datas in a grid. One of the field may contain values either text or a check box. So how can I implement a column which have only text in some rows and the some rows having check boxes.
Which control should I use, a Data Grid or a List Control?
thanks in advance.
regards,
Rajesh

It's really up to you, and dependent on your familiarity with each, other app specific details.
I'd also throw in a recomendation for GridCtrl (by our very own C Maunder), and the newer version posted a few months ago. They can take data from a variety of sources, and you can have cells with all sorts of type of data. Checkbox, text, number, colour pickers and (written by me!) progress bars.
