Colors are represented by red, Green, and blue values (RGB). To get a color between two colors, average their RGB values:
R = (R1 + R2) / 2;
G = (G1 + G2) / 2;
B = (B1 + B2) / 2;
Where color 1 is (R1, G1, B1), color 2 is (R2, G2, B2) and the between color is (R, G, B).

hi
i have one view base class is CFormView.when i Resize my application. View size also changing , Which is expected but all the controls in are not visible. Here I need scroll bar for this view in this situation to view all controls. In resource view I enabled vertical and horizontal scrolls but its not working. please help me how to do it..
|

Yeah - you need to handle scrolling yourself. You need to:
- When the view is resized, work out if it's big enough to display all the controls. If it is, then disable the scroll bars. If it isn't, then you need to use
SetScrollInfo[^] to tell the scrollbars how to display themselves. - You need to add OnVScroll and/or OnHScroll handlers to deal with scroll messages. Use SetScrollPos[^] and ScrollWindow[^] to tell the view about the scrollbar parameters so it can work out which bit of the form should be displayed
Yeah, it's a pain. Microsoft do supply a CScrollView...but that inherits from CView, as does CFormView - and MFC is a bit backward when it comes to OOP.

Hi,
I am compiling the legacy code in VS.Net 2008 64 bit platform. I am getting the above error in the following line
static HRESULT copy(destination_type* pTo , const int source_type* pFrom)
how to resolve the above error?
Please help me
Regards

What are destination_type and source_type meant to be?
Also - "const int source_type* pFrom" looks wrong no matter what source_type is (unless it is nothing)

This is the definition
template <class MapType, class DestinationType = MapType::referent_type>
and source type is defined as
typename MapType::value_type source_type;
what is wrong here?
|
|
|
|
|
const int source_type* pFrom
You have two types in that parameter declaration. Let us say that source_type is std::string - that translates to
const int std::string* pFrom
That doesn't make sense, now, does it?

get out to what the original types are solved.
Try to make the first or the second paramater to void* to check which parameter is the error.
Press F1 for help or google it.

I figured out why it doesn't work in visual studio c++. Here is the correct code I used to fix my error C2143:
#include "Wave.h" /* This header file has the CWave class in it */
CWave *wave1;
int main()
{
wave1.Load(_T("C:...\Music.wav"));
wave1.Play();
Sleep(100000);
}

//int a=2;
c = Add(5, 6);
Console.Write(c);
}
}
-------
when i run prog .i get run time exception
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'trydll.dll

Is that the working directory of your application ? Make sure this is the case. I'm not a C# expert but I suppose you can find that in the project options.
|
|
|
|
|
yes i put it in working dir
|
|
|

you need to put the mangled name for the function.
[DllImport("/*put the path of the dll*/")]
public static extern int Add/*mangled function name instead of Add*/(int a, int b);
You need to google first, if you have "It's urgent please" mentioned in your question.

Are you talking about any Source Code Management tools ?
Please go through these sites and rephrase the question ...
