It is easy to access the dc of a radiobutton / checkbutton - Via onctlcolour() / WM_CTLCOLORSTATIC. However who can tell me how to override the default drawing of the WHITE CIRCLE / SQUARE and its CHECK / TICK ONLY. Where the hell is it drawn and how? I want to be able to change the colour of the dot in the radio button or tick in a checkbox while leaving the rest of its processing as default. I know how I could implement this with an owner draw class and bitmaps, but I cant find ANY information as to how the default drawing occurs. Where is it hidden? Does ANYBODY know

Those weren't made to be customizable (well, pre-XP at least). The button part is drawn by the common controls library. In XP it's handled by the visual styles ("themes") system.

While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate.

I was wondering can I pass a vector reference as an argumnet to a function?
Like
I can do the following: void myfunction(int & myarray[10][10])
there by passing reference to a two dimensional array as function argument.
But when I try the folloing I get compilation error
I have a class called 'Myclass'
In this class I declare a function called 'Myfunct' the declaration is as follows:
void Myfunct(vector |Myclass| &mc);
//I am trying to pass a reference to a vector of type 'Myclass'
//I get error message
Does this mean I cannot pass reference to a vector as argument?
|

What's the error ? I just did this:
#include "stdafx.h"
#include <vector>
#include <iostream>
using namespace std;
int MyFunc(vector<int> & vec)
{
return vec.size();
}
int main(int argc, char* argv[])
{
printf("Hello World!\n");
vector<int> MyVector;
MyVector.push_back(1);
MyVector.push_back(3);
MyVector.push_back(72);
cout << MyFunc(MyVector);
return 0;
}
and it works fine.

Hi friends!
Do you know the GradientFill function at Visual C++?
I have acquainted with this function when studying graphic.
And the contents are like below.
( for more information, please refer to MSDN )
/////////////////////////////////////////////
”Drawing a Shaded Triangle”
TRIVERTEX vert [4] ;
GRADIENT_TRIANGLE gTri;
vert [0] .x = 0;
vert [0] .y = 0;
vert [0] .Red = 0x0000;
vert [0] .Green = 0x0000;
vert [0] .Blue = 0x0000;
vert [0] .Alpha = 0x0000;
vert [1] .x = 100;
vert [1] .y = 0;
vert [1] .Red = 0x0000;
vert [1] .Green = 0x0000;
vert [1] .Blue = 0xff00;
vert [1] .Alpha = 0x0000;
vert [2] .x = 100;
vert [2] .y = 32;
vert [2] .Red = 0x0000;
vert [2] .Green = 0x0000;
vert [2] .Blue = 0xff00;
vert [2] .Alpha = 0x0000;
vert [3] .x = 0;
vert [3] .y = 32;
vert [3] .Red = 0xff00;
vert [3] .Green = 0xff00;
vert [3] .Blue = 0xff00;
vert [3] .Alpha = 0x0000;
gTRi[0].Vertex1 = 0
gTRi[0].Vertex2 = 1
gTRi[0].Vertex3 = 2
gTRi[1].Vertex1 = 0
gTRi[1].Vertex2 = 2
gTRi[1].Vertex3 = 3
GradientFill(hdc,vert,4,&gTRI,1,GRADIENT_FILL_TRIANGLE);
///////////////////////////////////////////////
And I have two questions.
1.GradientFill(hdc,vert,4,&gTRI,1,GRADIENT_FILL_TRIANGLE);
I’m curious to know the internal algorism of Visual C++’s materializing (as a picture) when there is given arguments on GradientFill().
2.vert [3] .Green = 0xff00;
I know RGB rule express 256 colors, from 0 to 255.
But GradientFill controls the color through hexadecimal.
I’d like to know how I can turn colors by hexadecimal into RGB 256 colors.
Maybe, there is a rule. I’d like to know what it is.

1. I dunno, but I'd imagine it's just the obvious one.
2. Green = 00ff00 because 0xFF = 255, so it's just a case of 0 Red, 255 Green, 0 Blue = Green. COLORREFs are created with the RGB macro which just shifts the values passed in to create the DWORD that holds it ( COLORREF is a typedef for DWORD ). To get the red/green/blue values out of a COLORREF ( which .xff00 is, just stated in hex ), just use the GetRValue/GetGValue/GetBValue macros.

At risk of stating the obvious, as M$ do not give us the source, I really cannot tell you more than the MSDN tells you.

I'm confused as to why you think I know more than I have said. Do you know what linear means ? The MSDN says it's a linear transition, which is what I meant when I said it's probably the most obvious way. If you had 255 pixels you needed to do a gradient on, and you needed, for example, your red value to move from 0 to 255, how would *you* do it ? I'd step by 1 every pixel. If I had 510 pixels, I'd step by 1 every second pixel and if I had 127, I'd step by 2 every pixel. Extrapolate that to values that are a bit harder to calculate on the fly and that's about as much as I can tell you.

Here's a hint for you - if you're going to use a fake email address, at least don't ask for a cc email when people reply to you.

I am not sure this is the right section.
I am having a problem with the VS installer. I am creating a simple install file for a project with one executable. I have a shortcut in the start menu.
What I want to do is create an uninstall shortcut right next to the programs shortcut. I can't figure out how and I can't find any sources.
Can anyone help me, please?

I don't know, but FWIW I'll point out two things:
1/ the installer that comes with VC is a cut down version of Install Shield. Apart from being hard to use, the cut down version was useless in my opinion. We moved to Setup Factory.
2/ M$ recommend not doing what you want to do, because not all programs do it, and so expecting it stops users from realising there is an add/remove programs area in the Control Panel, which is where they should be going.

Hi,
all
Now I use this StretchBlt() function to display a
Rectangle bitmap ,It works perfect.But if I just want to
display the Ellispe inside the Rectange bitmap, how I
should do then. Perhaps, are theree other functions can
achieve this goal?
Thank you for your advanced help.
Regards.

You need to do one of the following:
1/ Not target Windows 95, then you can use TransparentBlt or GDI+
2/ Get my code from the WDJ site for the Sept 2000 issue, it includes a version of TransparentBlt that works with W95
3/ Do it yourself, this involves generating a mask bitmap in order to do the transparent blt. MSDN explains how, or again refer to my code from the WDJ site.

I'll like to add in a window like that of VC++'s output window where I can generate lines of text output and double-clicking would highlight the whole line. What type of view is that? I figure it closest to CEditView, but it mustn't let the user type into it!

It's not one of the MFC view class windows.
It's a custom created window.
Try the BCG class library which has an almost identical control.

You can try with a CListCtrl.
