my aim is to create a key board driver, i got a program from the net and it is working but i have to focus the the keyboard events to a desired window (say ms word). what changes should i make in the following codes.
#include "mian.h"
#define MAX_COUNT 50 // Max number of keystrokes to remember
#pragma data_seg(".shared") // ".shared" is defined in exports.def to allow
// all instances of the dll to share these variables

HHOOK m_hHookKey = 0;
HWND m_hHwndMouse = 0;

int m_nLastPos = 0; // Last position used in the buffer
HCURSOR m_hCursorLast = 0; // These two values are used to copy the mouse

A while back I read something telling me that there was a way to call a base class function from the child class; does anyone know how to do this? Thanks!!
If it's broken, I probably did it

Baseclass::function

or simply function() if the child class do not have a function with the same name where the base class declare this function to be virtual...

What's the best way to write HTML code to a file? Is it simply to write the raw tags or are there some libraries around that simply this? Thanks in advance.

Just write tags like if you were writing some kind of text. save it as you would do with a text file. is the same, but put the .htm extension.

wouldn't you prefer declare me as a bool& or even a bool* instead ?

Depend on his religoius philosophy; whether me destructs when leaving life's scope. (That's almost nausiatingly poetic in a nerdy sort of way. Don't think of it as dying, think of it as going out of scope.)

As a bool, it consumes 1 byte. As a bool*, it would consume 4 bytes. Correct? If so, future posts would therefore be 300% larger than necessary!

ok for the bool*, but that was an expectation for getting me out of the scope. but what about a bool&?

Michael Dunn told me "Use the CCS_NOPARENTALIGN style".
I've used it but what I win with this is that I can set up the height free, but I am not able to put 30 pixels from left for example. I use this function to call the CToolBarCtrl:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN, CRect(0, 110, 80, 80), this, IDC_MY_TOOL_BAR);
If I set up like this:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN, CRect(30, 110, 80, 80), this, IDC_MY_TOOL_BAR);
The top fails... I don't know what to do...
Please, if you could put me an example of how to create a CToolBarCtrl with no top or bottom alignment into the window... I want to draw it into a CRect from the Window.
Thanks in advance !!!

Well, I solved it:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN|CBRS_NOALIGN|CBRS_FLYBY, CRect(30, 110, 80, 80), this, IDC_MY_TOOL_BAR);
Thanx anyway !!

Hi all! I had a question concerning visual c++ 6.0. I'm coding a card game in Win32 (no MFC) and am trying to fill an edit box on a dialog window dynamically with child controls. What the program does is it queries the current directory for all sound (.wav) files and, for each sound file, inserts three child controls in the edit box on one line. The controls are, from left to right, an edit box for the caption the user wants for this sound file, a play button to listen to the sound, and a second edit box for the name of the sound file.
I'm inserting these into an edit box because, since the sound list is obviously dynamic and of arbitrary length, I'd like to utilize the scroll bar on the edit box. The problem I'm running into is that the edit box is unaware of anything being added to it. I'm calling CreateWindow to add these controls to the edit box, with the handle to the edit box as the parent parameter, and the lines of child controls for the sound files fill up past the depth of the edit box without the scroll bar being activated.
One solution I tried was to insert a newline character into the edit box for each line of controls I added. This solved the scroll bar problem, but when you scroll the edit box the display gets really confused as to what to display (the controls or the "\n").
Any advice is GREATLY appreciated.

I've never heard of anything other than text being added to an edit control. Do you have an example that shows this?

I'm envisioning a list control with two "columns," one for caption and the other for filename. Each of these can be edited in place. A "Play" button would reside next to the list control and would act upon whatever file is currently selected.

That is a good point, and it need not be an edit box at all. I'm just looking for something like an edit box with scroll controls that I can add dynamic child controls inside of. Do you have any suggestions?

Here is a code snippet:
int xDim = 0;
int width = SOUND_CAPTION_BOX_WIDTH * cxChar;
//SendMessage(hList,EM_SETLINE,int((idx - SND_FILE_LIST_OFFSET)/HWNDS_PER_SOUND),(LPARAM)TEXT("\n"));
SendMessage(hList,LB_INSERTSTRING, 0, (LPARAM)TEXT("\n\n"));
captionRef = CreateWindowEx(
WS_EX_CLIENTEDGE,
"EDIT",
NULL,
//WS_CHILD | WS_VISIBLE | WS_BORDER | ES_LEFT | WS_THICKFRAME,
WS_CHILD | WS_VISIBLE | ES_LEFT,
xDim,
yDim,
width,
cyBox,
hList,
(HMENU)idx,
hInstance,
NULL);
SetWindowText(captionRef,caption);
idx++;
numActiveSoundChildWindows++;
xDim += width;
width = SOUND_PLAY_BTN_WIDTH * cxChar;
playBtnRef = CreateWindow(TEXT("button"),
TEXT(" PLAY "),
WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
xDim,
yDim,
width,
cyBox,
hList,
(HMENU)idx,
hInstance,
NULL);
idx++;
numActiveSoundChildWindows++;
xDim += width;
width = SOUND_FILE_NAME_BOX_WIDTH * cxChar;
fileNameRef = CreateWindowEx(
WS_EX_CLIENTEDGE,
"EDIT",
NULL,
WS_CHILD | WS_VISIBLE | ES_LEFT,
xDim,
yDim,
width,
cyBox,
hList,
(HMENU)idx,
hInstance,
NULL);
SetWindowText(fileNameRef,fileName);
idx++;
numActiveSoundChildWindows++;
yDim += cyBox;
the 'hList' is the handle to the edit box.

Hi!. i want to overload operator >>. What i've done so far doesn't work. I'm using visual C++ 6.0. When i place my mouse cursor over s, it says int s. It's the same if instead of writing 'std::string s' i write 'string s', even though in the header file i declared 'typedef std::string string;'
<br />
istream &operator>>(istream& stream, XML &x)<br />
{<br />
<br />
std::string s;<br />
std::getline(stream,s);<br />
x.fromString(s);
return stream;<br />
}<br />
This is how i declared inside the class in the header class.
<br />
friend istream &operator>>(istream &stream, XML &x)
this is what i'm including and using in the header file.
<br />
#include <iostream><br />
using std::istream;<br />
using std:stream;<br />
and in main: using namespace std;
my class is called xml
in main i declare:
<br />
xml table;<br />
cin >> table;<br />
thanks!!

Hi,
First of all, please tick the "Notify me by e-mail if someone answers this message" checkbox on (right below the editbox for entering the post) so that <'s appear correctly.
As for your problem, which is the behavior you observe? Does the program compile and you get weird results, or if it fails to compile what's the error? With a little more info we'll do a better job trying to help you.

well, it compiles, and i need to load a string (s)from standard input, but as s is thought as an int, nothing gets loaded in s. And i need a string to be loaded in s so i can call the function toString
thanks!

Well, I don't think your s is really compiled as an int: sometimes the intellisense feature (by which you guessed the variable was being treated like an int) gets crazy, that's all.
I'd try the following:
1. Make sure you already have a proper #include<string>.
2. To rule out some problem with getline, replace that line (just for testing purposes) with something like
s="hello world"; or whatever. What happens now? Does this shed some light on your problem?
3. After the getline output the contents of s to cout to see what it has been fed with.
Hopefully, some of these measures will make it clear where the problem lies. Good luck, don't hesitate to come back if you can't come up woth a solution.
