Or you loop through FindWindow and FindWindowEx which provide same functioality like EnumWindows and EnumChildWindows

I am using _asm{...} inside a member function of a class. within the _asm{..} I am not able to access the member variables. The compiler generates an error "variable referenced but not defined".
Why is this happening?
USING INTEL COMPILER
CODE:
/////////////////////////////////////////
#include <xmmintrin.h>
#define A16 __declspec(align(16))
class SomeVar
{
public:
SomeVar();

A16 float xx[4]; A16 float yy[4]; A16 float ww[4];
void Update();
};
SomeVar::SomeVar()
{
for(int i = 0; i < 4; i++)
{
xx[i] = 1.0; yy[i] = 1.1; ww[i] = 0.0;
}
}
void SomeVar::Update()
{
__asm

printf("\n%f %f %f %f\n\n",ww[0],ww[1],ww[2],ww[3]);
}
SomeVar sv;
int main(int argc, char* argv[])

sv.Update();
return 0;

Inside of the Update() method, declare three local variables that hold the contents of the member variables. Then in the __asm block, reference the local variables.

I think you are referring to a system-model dialog box.

The name is misleading. It is the SDK you want for Windows 2000.

What part of "The name is misleading. It is the SDK you want for Windows 2000." was unclear.
Download it. Install it. Enjoy!

How to use Different font sizes in a VC++ Dialog Box
|
|
|
|
|
Right click on dialog select properties; from the general tab select the font size you want.
|
|
|
|
|
If you want to do it at run time, override the virtual function DoModal();
#include <afxpriv.h>
int CMyDlg::DoModal()
{
CDialogTemplate dlt;
if (!dlt.Load(MAKEINTRESOURCE(CMyDlg::IDD)))
{
return -1;
}
WORD nFontSize = 10;
TCHAR chFaceName[100] = "Courier New";
if (GetNewFontSize(....))
{
nFontSize = newsize;
}
if (GetNewFaceName(....))
{
lstrcpy(chFaceName, newfacename);
}
dlt.SetFont(chFaceName, (WORD)nFontSize);
LPSTR pData = (LPSTR)GlobalLock(dlt.m_hTemplate);
if (pData == NULL)
{
return -1;
}
m_lpszTemplateName = NULL;
InitModalIndirect(pData);
INT nResult = CDialog::DoModal();
GlobalUnlock(dlt.m_hTemplate);
return nResult;
}

I use a method similar to this with a highres app and it works great. On a highres monitor (2048 x 2560) I use 15pt font and on the second (1024x768) I use 10pt...

Hi all,
I'm new to C++ and am trying to write a kind of predictive text program where the text from a file will attempt to be predicted by the program. Atm I'm trying to get started by reading the text from the file a character at a time and having each character be displayed to the screen after a press of a key. I've managed to read the text and display it as a complete word but am having trouble reading and displaying it a character at a time. I've messed around with cin.get, cin.getc, cin.getchar etc and can't seem to get them to work correctly 
Any help on how to go about doing this would be greatly appreciated, Thanks.
The short program below is how I read the text from the file and displayed it to the screen:
Note, to avoid the console window disappearing, you have to run it using CTRL+F5. If there is another way to stop it closing please let me know. I'm using MS Visual C++.NET btw.
=====================
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main()
{
char buffer[256]; // Create 256 bit character array.
ifstream file_op; // Create an output stream variable.
file_op.open("mytext.txt"); // Open the text file to read from.
while(file_op >> buffer)
cout << buffer << endl; // Display complete text (complete word)
file_op.close();
return 0;
}
|
|
|
|
|
look in the help for getch(); you will need to include stdio.h.
|
|
|
|
|
Why not change buffer to be a single character?

A executable file which has compiled, How to insert it into IE?can you help me ,please tell me some about it,Thanks!
|

I believe your asking how to run an true exe (machine code) inside a browser. This is impossible for two reasons:
A) Browsers are not OSes they only display the contents of HTML pages and a few other formats. Additionally, a browser is not going to translate your code into code compatible with the visitors system.
B) Some plug-ins and scripts do allow for functionality similar to a program but they are intentionally made restrictive so that web authors cannot attack web surfers with malicious programs.
That being said, their are ways to write programs for browsers that are not true machine code. The most popular by far is Java code. This can be done through what are called Java Applets. The limitation to this is that each user will need to install your applet and accept it through a dialog that pops up when they go to your page if it contains code that could possibly harm the users computer. For a detailed explaination check out this site: http://java.sun.com/sfaq/

Thanks a lot!I find some web pages have a program such as realoneplayer,maybe i express incorrectly my idea,can you tell me how to do it ?

To do that you would need to create a plug-in for each browser that you would like to support. This is not a small task. Unless you absolutely need a plug-in (which isn't very likely) I would recommend making an applet. If you really want to make a plug-in for IE try this link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnanchor/html/anch_webdev.asp
If you want to play music from a browser you can do that with an applet. In fact their are some already made that are very customizable and easy to use and free that may give you an idea of what is possible with an applet as far as Javas' audio capability. Here is a link to one that I use on one of my sites:
