how can this be used with vc++ program I create.
waiting for reply

You know I am not sure, there is so many meanings that it boarders on the ridiculous.
1) Windows programming: memory, icons, bitmap, dialog boxes, I/0, and strings.
2) C++: memory, I/O.
Oh, 1 applies to Mac programming too.
A resource is anything that you must draw on to accomplish the goal, including dependency on outside resources such as the Web.

In a Visual C++ program, visual elements in your program (menus, dialog boxes, bitmaps, icons, and some strings) are defined in a source file with the extension .RC, which is referred to as a resource script. This file is compiled and 'linked' into your program. The term "resources" refers to these visual elements.

the DC functions: Ellipse, Rectangle ... are filled by current brush.
I hope they are draw only without been filled.
any idea to do this?

You can use from Graphic like this
<br />
SolidBrush Brush(Color(255,0,120,120));<br />
Pen pen(&Brush, 4.0f);<br />
Graphics graphics(GetDC()->m_hDC) ;<br />
graphics.DrawEllipse(&pen,100,100,200,200);<br />

Can you be more specific
and you need to using namespace Gdiplus;

I have vs2003 and you can see MSDN for Graphics

I seen the reference to ‘graphics’ and understand we are at a crossroads between systems of programming for windows. That being said ignore it and select a NULL brush before drawing the ellipse.

Hi John R. Shaw,
you said that create null brush before draw ellipse in CDC
but in graphics if you run this code you see a ellipse with one stroke

we target to win95/98 and use VC6.
NULL brush, I tried it before in this way:
CBrush*pb=0;
dc.SelectObject(pb);
but the select is ignored (previous brush is still working).
any comment about null brush?
|

|
|

That's not what he meant by null brush.
dc.SelectObject(GetStockObject(NULL_BRUSH));
|
|

Thanks hfry, I have been away and you and others pointed out what I was saying.

how to select a null brush?
|
|
|
|
|
<br />
CPaintDC dc(this);
dc.SelectObject((HBRUSH)GetStockObject(NULL_BRUSH));<br />
dc.Ellipse(100,100,200,200);<br />
<br />

thx.
it works fine on screen - hope the same for printer.

My project was been written in VS 6, when I build it in VS 8 :
error C2872:'unary_function' ambiguous symbol.
How can I resolve this problem?
Thanks forward...

As a first step I would suggest googling on the topic "Breaking changes in Visual C++" and see what turns up. Between version 6 and 8 MS have increased C++ standards compliance, so some older code may well be broken.

Hi,
Having a little trouble with FindFirst File function.... heres what ive got...
include "stdafx.h"
#include <string>
#include <direct.h>
//#include "dirent.h"
#include <winsock2.h>
#include <fstream>
#include <vector>

#include <stdio.h>
#pragma comment(lib,"ws2_32")
using namespace std;
// Stuff.......
char fileFound[256];
strcpy(fileFound, path1);
WIN32_FIND_DATA FindFileData;
HANDLE hp;
hp = FindFirstFile(fileFound, &FindFileData);
printf ("The first file found is %s\n", FindFileData.cFileName);
FindClose(hp);
The error i recieve is...
error C2664: 'FindFirstFileW' : cannot convert parameter 1 from 'char [256]' to 'LPCWSTR'
I know sometimes when compiling the error is not always what it seeems.. but have no idea..
Please help.

can you tell me what type of application are you working on?
MFC , Console or On something else because I tried executing your code in MFC application and apart from a very minor change I was able to get the result.

Hi,
Im using Visual Studio 2005 but ive figured that part out via searching long and hard on the web... however im stuck with another problem just the same....
heres what i got for that part....
std::wstring s2ws(const std::string& s){
int len;
int slength = (int)s.length() + 1;
len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0);
wchar_t* buf = new wchar_t[len];
MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);
std::wstring r(buf);
delete[] buf;
return r;
}
#ifdef UNICODE
std::wstring stemp = s2ws(ipp); // Temporary buffer is required
LPCWSTR result = stemp.c_str();
#endif
WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE;
char DirSpec[MAX_PATH + 1]; // directory specification
DWORD dwError;
hFind = FindFirstFile(result, &FindFileData);
printf ("First file name is %s\n", FindFileData.cFileName);
My problem is i cant seem to get the FindFileData function to return a readable string...
but i need FindFileData to be string s; for example...
|
|
|
|
|
Should get it now.
strcat(result,"\0");
hFind=FindFirstFile(result,&FindFileData);
Do you get the name of the file or not?
