You have create the region of the ellipse dimension.
Crgn rgn;
rgn.BeginPath()
pDC->Ellipse(CRect(0,0,100,120));
rgn.EndPath()
rgn.CreateRgnFromPath();
rgn.FillColor(RGB(255,255,255));

check the CreateRgnFromPath

If none of the stock brushes fits your needs you've to create a new brush, for instance:

CBrush redBrush(RGB(255,0,0)); // create your new, red brush
CBrush *pOldBrush;
pOldBrush = pDC->SelectObject(&redBrush);
pDC->Ellipse(CRect(0,0,100,120));
pDC->SelectObject(pOldBrush);

Hello everyone,

The command dv is not print the correct value for input parameters? Here is my WinDbg debug on x64 platform and source code. Any ideas about how to retrieve the correct value?

0:000> bp foo
0:000> bl
 0 e 00000001`40001020     0001 (0001)  0:**** Test64bitDebug!foo
0:000> g
Breakpoint 0 hit
Test64bitDebug!foo:
00000001`40001020 89542410        mov     dword ptr [rsp+10h],edx ss:00000000`0012fea8=cccccccc
0:000> dv
              a = -858993460
              b = -858993460


int foo (int a, int b)
{
	return a+b;
}

int main()
{
	int a1 = 100;
	int b1 = a1 + 100;

	foo (a1, b1);

	return 0;
}

thanks in advance,
George

How can I make theme-awared transparent control with UXTheme library (MFC / VC++ 2005)

I have a request to make my currently developing program look less dull.
(the program is some kind of speech training/patient database front end program use for disabled childrens / physician so it going to look somewhat lively).

so I draw the background using GDI plus (in WM_PAINT/OnPaint).

since now my dialog had a background it also required the text path of other control like static text,group box and checkbox/radio button to be transparent.

I try using some basic method by sub-classing the control and override
WM_CTLCOLOR_REFLECT of the said class then set background mode to transparent and return HOLLOW_BRUSH , NULL_BRUSH .

But like everybody known , those method above only work for static text control.

calling pDC->SetTextColor on button(push,radio,check)/group-box
doesn't even change the text color of these control.

I guess that when the theme is enable Windows XP/VISTA doesn't use those information (background mode/text color) to draw the button control (push,radio,check) and group-box anymore.

My guess is that I have to do an owner-drawn by override OnDrawItem and draw the button based on it stage.

but since I only want the text-background of the control to be transparent
have to totally redesigned/drawing the checkbox/radio button is to much
(and it not gonna look like the standard-themed one).

then I found some info on these UXTheme library,can this library help in some way?

I really hope that someday MFC will come with those set bitmap,set color text,set transparent function so that I will not have to jeliously look at
.NET / VCL anymore since I am going to live with native c++ for a very long time.

Sorry for my bad english.

Thank in advance.

i can't understand why this result is showed~

if i input three string,
test1
test2
test3

and result is
test1
test2
test3
test3

as you can see, test3 show two times.
why that result come?

void main()
{
char data[100];
int i;
FILE *fp = fopen("D:\\Code\\test\\input.txt","rt");
int lens;
int num;
char ch;
if(fp == NULL)
{
puts("Error");
exit(0);
}

while ( !feof(fp) )
{
fgets(data, sizeof(data)-1, fp);
fputs(data, stdout);
}

fclose(fp);

}

firstly, i am sorry, i am from korea.
and i am not good in wriitting english so please understand~
Thank you everyone~

Your code appears to be correct.
Did you cross check if that file contains three entries only?

Somethings seem HARD to do, until we know how to do them.

Check the documentation of fgets:

If the End-of-File is encountered and no characters have been read, the contents of str remain unchanged and a null pointer is returned.

The end of file is detected once you try to read after the last character of your file. So, in your case, you will still execute fputs even if the eof was detected. You should do something like this instead:

char* pTemp = fgets(data, sizeof(data)-1, fp);
while (pTemp)
{
   fputs(data, stdout);
   pTemp = fgets(data, sizeof(data)-1, fp);
}

EDIT: oh and BTW, this kind of problem can be tracked quite easily by using your debugger. It is much faster than asking a question on a forum Wink | ;)

Modify your while loop as below

while ( !feof(fp) )
{
   if( fgets(data, sizeof(data)-1, fp) == NULL)
        break;
      else
         fputs(data, stdout);
}

Because: Your file ends with an empty line and your program doesn't check fgets return value.
Change

Assuming you're using C++ forget about all that C-style file manipulation bollocks and do something like the following:

// VanillaConsole.cpp : Defines the entry point for the console application.
//
 
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
 
int main()
{
	ifstream ifs("C:\\Data.txt");
	if (!ifs)
	{
		cerr << "Failed to open file!" << endl;
		return -1;
	}
 
	string line;
	while (getline(ifs, line))
	{
		cout << line << endl;
	}
 
	return 0;
}

Easier to understand and no limit on the length of a line.
