C++ = "C plus plus"
Windows 2000 = "Windows two thousand"
Hope this helps.

C plus plus. Most programmers I know say "win 2K" or just "2K" when referencing Win 2000.

Maer727 If you concentrate on naff stuff like this in a section about C++ programming techniques then I;m afraid there's not much hope for you in programming.
Concentrate on the real work and leave the nonsense behind.

- In MSDN(Ti:SystemParametersInfo), it is said "fWinIni ... This parameter can be zero if you don't want to update the user profile or broadcast the WM_SETTINGCHANGE message ... ".
- I do not know what means "user profile" here.
- Can you show me an example?

I've understood that all the minimized windows can be grouped into a single bar, called taskbar just like the windows taskbar, but i don't know how can i make that the minimized windows don't have the restore button, and all the rest. So my question is how, can i build a taskbar into an app?, using the doking windows?, or how?

- In MSDN (Ti: NONCLIENTMETRICS), first paragraph, it is said "The NONCLIENTMETRICS structure contains the scalable metrics associated with the nonclient area of a nonminimized window. "
- I do not know what means "scalable metrics" here.
- Can you show me an example?

Here is my problem! I have three classes set up sort of like this:
class MainClass
{
CSocketClass * pSock; // instance of my socket class.
}
class CSocketClass
{
CSocketAddr * pObj;
};
class CSocketAddr
{
operator LPSOCKADDR()
{
return ( LPSOCKADDR )( LPSOCKADDR_IN )this;
}
}
When I call my MainObject->pSock->bind() [which uses my LPSOCKADDR override] and try to do some binding, the pointer this does not refer to the class I called it from, it points back to my main object! That is bunk! When I say "this" I want the class I am calling in. Is it just me?
Peace.

What does you bind function look like?
Todd Smith
|
|
|
|
|
void XSocket::bindAddress()
{
if( ::bind( m_hSocket, ( LPSOCKADDR )m_pAddress, sizeof( SOCKADDR ) ) == SOCKET_ERROR )
throw "bindAddress";
}
Well, not anymore...
I got around this by not overloading operators and calling member funcs explicitly. It still p1ss3s me off though! I think the "this" pointer within a class should reference the class it is within.
Peace.

I've Created a Internet Explorer Bar using vc 6.0.My project can run smoothly in Windows 2000,But in Windows Me,When I close IE,It will popup a error message which said "Iexplore have unknown error,will closed".
In my project,I use a MFC regular dll writed by myself,this dll has been tested ok.
Who can tell me what's the possible mistakes in my project?
|

|

The first one would be using Windows2000 api methods not available in Windows ME.
Cheers,

Hi all!
I made a dialog base application and wanted to use a class I wrote before. I copied the header file and the implementation file to the project folder and use "add files to project" option to add these 2 files. These 2 files are actually working files. However, when I tried to recompile the project, it kept giving me this error.
------Configuration: MyProject - Win32 Release----------
Compiling...
controllerList.cpp
D:\MyProject\MyPoint.cpp(188) : fatal error C1010: unexpected end of file while looking for precompiled header directive
Error executing cl.exe.
Does any one know what is wrong here?
Thank You
Vu
The class is very simple. If you need to have a look, here it is:
//---------------------
myPoint.h
//---------------------
#ifndef MYPOINT_H
#define MYPOINT_H
class MyPoint
{
private:
int x,y;
public:
MyPoint();
~MyPoint();
void setPoint(int,int);
int getX();
int getY();
};
#endif
//---------------------
myPoint.cpp
//---------------------
#include "MyPoint.h"
MyPoint::MyPoint()
{
x= 0;
y=0;
}
MyPoint::~MyPoint()
{
x=-1;
y=-1;
}
int MyPoint::getX()
{
return x;
}
int MyPoint::getY()
{
return y;
}
void MyPoint::setPoint(int x1,int y1)
{
x= x1;
y = y1;
}

Add #include "stdafx.h" to the top of your file

You have to either turn off use of precompiled headers or enable your class to use precompiled headers.
To turn off Precompiled Headers got to the menu. Select Project -> Settings..., select the C/C++ tab. Select Precompiled Headers from the dropdown combobox. Here you select Not using precompiled headers.
To enable your class to use Precompiled Headers add
#include "stdafx.h"
to the top off you classes header file before all other #include statements.

Just do a Rebuild all after having added StdAFX.h

I have a bitmap that I get from a third party decompressor of a video stream. The bitmap comes out at a resolution of 720*243 and 24-bits. I would to like to shrink it down and copy it to an offscreen bitmap that is 320*240 and 24-bits in order to speed up my motion detection algorithm and then blit that image to a screen without using the original image and StretchDIBits().
I believe I would want to create a CompatibleDC and a compatible bitmap to go with it then do a StretchDIBits to that CompatibleDC.
Am I right in this assumption and does anyone have some example code of how that is done?
Thanks,
Clint

You can also use CopyImage API function to resize the bitmap.

I think this is what I am looking for but what does it mean when it refers to the handle of the image. Would it be something like a HBITMAP?
Cheers,

You can pass HBITMAP in handle(First Parameter) of CopyImage.

Hi,
I am trying to draw a grid onto a CView.
The grid doesn't fit into the far right and lower bottom regions correctly. My suspicion is its some strange effect with rounding. It creates a strange effect when you look at the result after resizing the view.
Anyway it's only a small fragment of code, and i would be very grateful if someone would give it a whirl and give their diagnosis.
void CTestView::OnPaint()
{
CPaintDC dc(this); // device context for painting
CRect ScreenDimensions;
GetClientRect(ScreenDimensions);
POINT line[2]; //Array Of Points, Start And End Of Line
//Draw The Columns
for (int col=0; col <=50; col++)
{
line[0].x = ScreenDimensions.Width() / m_cols * col;
line[0].y = 0;
line[1].x = ScreenDimensions.Width() / m_cols * col;
line[1].y = ScreenDimensions.Height();
dc.Polyline(line,2);
}
//Draw The Rows
for (int row=0; row <=50; row++)
{
line[0].x = 0;
line[0].y = ScreenDimensions.Height() / 50 * row;
line[1].x = ScreenDimensions.Width() ;
line[1].y = ScreenDimensions.Height() / 50 * row;
dc.Polyline(line,2);
}
}
Cheers

To help with rounding errors, always multiply first, then divide.
The following works for me.
int m_cols = 42;
CPaintDC dc(this);
CRect ScreenDimensions;
GetClientRect(ScreenDimensions);
POINT line[2];
for (int col=0; col <= 50; col++)
{
line[0].x = ScreenDimensions.Width() * col / m_cols;
line[0].y = 0;
line[1].x = ScreenDimensions.Width() * col / m_cols;
line[1].y = ScreenDimensions.Height();
dc.Polyline(line,2);
}
for (int row=0; row <=50; row++)
{
line[0].x = 0;
line[0].y = ScreenDimensions.Height() * row / 50;
line[1].x = ScreenDimensions.Width() ;
line[1].y = ScreenDimensions.Height() * row / 50;
dc.Polyline(line,2);
}

I am currently writing an app that does not support doc/view. I want to be able to section of the FrameWnd into different views. I am able to split the windows fine at compile time. I want to be able to split the windows while the app is running. I tried to use the dynamic splitwindow but I had trouble because I am not using documents.
Does anyone have a sample of code that does this without using doc/view?
Or does anyone have any ideas?

(1) Add a CSplitterWnd to your CMainFrame class say m_split.
(2) Derive two view classes [say you have CMyTree and CMyList which are classes derived from CTreeView and CListView]
(3) m_split.CreateStatic(this,1,2);
(4) m_split.CreateView(0,0,RUNTIME_CLASS(CMyTree),CSize (150,100), NULL);
m_split.CreateView(0,0,RUNTIME_CLASS(CMyList),CSize (150,100), NULL);
Hope this helps

Thanks for replying,
This is what I had done for the original split window....
if(!m_ospltWindow.CreateStatic(this,1,2))
return false;
if(!m_ospltWindow.CreateView(0,1,RUNTIME_CLASS(CGraphView),CSize(200,200),pContext) )
return false;
if(!m_ospltWindow.CreateView(0,0,RUNTIME_CLASS(CChildView),CSize(200,200),pContext) )
return false;
I tried doing what you said for splitting one of the above splits but it didnt work. I have a menu option that when selected I want one ov the above splits to split again...know what I mean...
So in my OnSplitAgain function I had....
m_ospltWindow1.CreateStatic(m_ospltWindow,1,2);
m_ospltWindow1.CreateView(0,1,RUNTIME_CLASS(CGraphView),CSize(200,200),NULL);
m_ospltWindow1.CreateView(0,0,RUNTIME_CLASS(CChildView),CSize(200,200),NULL);
but it didnt work....
