hi,
In the CDialog Class Declare a CString Variable and also in the View Class when you populate the CDialog Class.
CView Class
CDialogInstance dlg;
dlg.strNameValue = strViewClassString;
dlg.DoModel();
Good Luck.

Do your dialogs have a parent child relationship.
If affirmative you can use
GetParent();
else
you will need to pass a pointer of your class in another class and after that you can start using the variable/s / data of one class from another.
eg :
CMyDialog *myDlg=new CMyDialog();
myDlg->m_pParent=this;
myDlg->DoModal();
and in the header file of the child include the dialogs header file(for calling class.)and declare CMyFirstDialog m_pParent;
Somethings seem HARD to do, until we know how to do them.

CMain* m_Main=(CMain*)GetParent();<br />
m_Main->values or functions<br />
-------------------<br />
(3)<br />

Thanks but its not fulfil my need..I have a seperate keyboard other than our system keyboard.
I have class for that as keyboard.cpp,if i press 1 in that keyboard it goes to WM_KEYDOWn in that class and it goes to OnKEyDown in that particular CView class which one is active,but the number should typed in Edit control of dialog which is invoked by clicking the view window.
The WM_KEYDOWn function only goes to avtive View CGrpView and not to that particular dialog.So,i thought to get that all values which are entered in seperate keyboard in to CString and then give this CString value to Edit control..
My Objective is : when i pressed 1 in seperate keyboard it should get entered in that edit box in the dialog..

I have problems following you, but maybe what you need is something completly different and is more along the lines of a "focus follows mouse" setting for the whole Windows-Gui?

You want when you click 1 it insert to edit and run wm_keydwon,right?
|
|
|
|
|
Yes, when i clicked 1 it goes to keyboard.cpp,ther i wrote
void CKBoard::OnLButtonUp(UINT nFlags, CPoint point)
{
case 51 :
ActiveView->PostMessage(WM_KEYDOWN,49,0); break;
}
It executes the line and then it goes to OnkeyDown() in that particular dialog,their i wrote..
void CFaceDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
case 49:
case 97:
sSktNumValue += "1";
break;
}
This is coding..when i debugged this coding the control after executing WM_KEYDOWN...It should go to Onkeydown() in that dialog..But the control goes to OnKEyDown() in te particular view where the dialog exist...So i wrote the codings of Dialog OnKeyDown() in to THat view class OnKeyDown() function.
Thats im asking is there anyway to get value which i pressed in keyboard go to dialog OnKeyDown or the control goes as it is View class OnKeyDown()but the final value should entered in that particular Dialog edit box...
Pls give any solution..

Hello! I am new to c++.
I am now trying to create a GUI based program using Microsoft Visual C++ 2005 Express Edition.
I have a question. I want that when I click the exit button, the whole program that I created will exit. Can anybody tell me how to do that?

Try ::PostQuitMessage(0);.

Thanks for your reply. But, your code doesn't work.

Should be
using namespace std;

actually tried with using namespace std; (I have mistakenly specified in
the previous message). still showing an error
error C2871: 'std' : does not exist or is not a namespace
You only have to do a very few things right in your life so long as you don't do too many things wrong.

Try doing this way :
#include "vector"
#include "iostream"
using namespace std;
What is the type of application and your IDE?

It is #include <vector> without the .h.
And you need to put the using std namespace; line after the include.

Oops, sorry, I read the line too fast. Of course, it is using namespace std;

hey all,
I am using CNTGraph class that was found in the codeproject website.
I can plot a graph that I want.
But there are 2things I want to do:
1. I want to replot the graph everytime I recieve a new set of data points.
How do I do it? Is there a 'clear' or 'delete graph points' function that can be used to clear the previous plotted points before a new set of data is plotted.
2.Also, how do I set the scale on X-axis and Yaxis?
say, I want the scale of the X-axis in terms of 2units.ie., X-axis range (I use SetRange()) is (0,10). but the scale has to be like 0 2 4 6 8 10? Is there a function to do this?
Can anyone help me?

Ask on the forum at the bottom of the articles, you'll perhaps have an answer from the author.
