I need information about programming plugins techniques. I currently wrote easiest scheme using DLL's with fixed set of exported functions. But it is preferred to have more flexible mechanism with various additional functions.
Any information, url's, etc. are welcome.

Like COM components? I'm not sure I understand your question.

Well, I'm not very familiar with COM though I know it can be used.
I need general information about plugins architecture, custom application APIs, etc.
Consider I wanna make somewhat like Photoshop 8BF filters. How could I build such a technique? I'd like to see different methods.

How to run the command of ["%ProgramFiles%\\Outlook express\\msimn.exe" /mail] under w2k?
|
|
|
|
|
I think you don't need to give the full path
Simply ShellExecute msimn.exe

But msimn.exe just is a instance.
|
|
|
|

I didnt understand what you meant.
But if you mean you want to start a separate instance of msimn.exe when it is already running, that's not possible. msimn.exe will allow only one instance at a time. If you attempt to start it again, it will activate the current instance.

My english is pool.The "Instance" meant Sample,not the Handle of program.
In my app,I want to run the Windows Default Mail Program.The code is following:
//...................
strDefaultMailCmd = registry.ReadString(strMailReg);
// the Value of strDefaultMailCmd: "%ProgramFiles%\\Outlook Express\\msimn.exe" /mail
if(!strDefaultMailCmd.IsEmpty())
ShellExecute(NULL,"open",strDefaultMailCmd,"",SW_SHOW);
But outlook express is not run.

Thanx

You need to use SHGetSpecialFolderLocation, SHGetSpecialFolderPath to convert "%ProgramFiles% to the actual path

I'm trying to change the font of a CTabCtrl. Can anyone help me?
|
|
|
|

CTabCtrl is derived from CWnd
You can use CWnd::SetFont

It worked. Thanks. Now how do I change the font color and make it bold? I searched the MSDN but, being a newbie, I didn't know what I was lookin' for.
|
|
|
|
|
making it bold is easy
just set a suitable nWeight if you are using CreateFont or a suitable lfWeight if you are using CreateFontIndirect and making the font from a LOGFONT
not sure its that easy to change the color
You might have to owner draw or something

I am using just DOS based C++ and need to know how to redirect the output to go to the printer. This is what I have to work with but am not sure ow to implement it in the .h
ofstream printer("LPT1",ios::out)
printer << data << "line of code";
Any ideas?

Hi,
Would you please tell me that how to
get and set the rgb color for each pixel in a
bitmap image. In addition, are there getpixel()
and setpixel() functions in CDIB class?
Thanks in Advance!
chen

Well, you could use GetPixel/SetPixel but that's pretty slow. Any DIBSection wrapper ( which I presume CDIB is ) would however store a pointer to the bitmap data, which you can then access directly.

Thanks for your reply!
I cannot find the GetPixel() and Setpixel() functions
in CDIB class Lib. Would you please show these source
code?
chen

I dunno what CDIB is, CDC is the class that has the Set/GetPixel methods, and they are still VERY slow.
Where did you get the CDIB class ? Is it a DIBSECTION wrapper ?

The CDIB class i used is wrote by Jorge Lodos (lodos@cigb.edu.cu) in 1998.
But there is no GetPixel and SetPixel function.
It looks like that:
// dib.h
#ifndef _INC_DIB
#define _INC_DIB
/* DIB constants */
#define PALVERSION 0x300
/* Dib Header Marker - used in writing DIBs to files */
#define DIB_HEADER_MARKER ((WORD) ('M' << 8) | 'B')
/* DIB Macros*/
#define RECTWIDTH(lpRect) ((lpRect)->right - (lpRect)->left)
#define RECTHEIGHT(lpRect) ((lpRect)->bottom - (lpRect)->top)
// WIDTHBYTES performs DWORD-aligning of DIB scanlines. The "bits"
// parameter is the bit count for the scanline (biWidth * biBitCount),
// and this macro returns the number of DWORD-aligned bytes needed
// to hold those bits.
#define WIDTHBYTES(bits) (((bits) + 31) / 32 * 4)
class CDib : public CObject
{
DECLARE_DYNAMIC(CDib)
// Constructors
public:
CDib();
public:
CPalette* m_pPalette;
LPBYTE m_pBits;
LPBITMAPINFO m_pBMI;
public:
DWORD Width() const;
DWORD Height() const;
WORD NumColors() const;
BOOL IsValid() const { return (m_pBMI != NULL); }
// Operations
public:
BOOL Paint(HDC, LPRECT, LPRECT) const;
HGLOBAL CopyToHandle() const;
DWORD Save(CFile& file) const;
DWORD Read(CFile& file);
DWORD ReadFromHandle(HGLOBAL hGlobal);
void Invalidate() { Free(); }
virtual void Serialize(CArchive& ar);
/* new added by chen 2001.11.14*/
void SetPixel( int iX, int iY, RGBQUAD& rgbPixel );
RGBQUAD GetPixel(int iX, int iY);
void AssertPosition( int iX, int iY );
// Implementation
public:
virtual ~CDib();
protected:
BOOL CreatePalette();
WORD PaletteSize() const;
void Free();
public:
#ifdef _DEBUG
virtual void Dump(CDumpContext& dc) const;
#endif
protected:
CDib& operator = (CDib& dib);
};
#endif //!_INC_DIB

Dear Christian,
My really problem is:
In order to change the colour of the text in a bitmap image,
the text is viewed as image pixels. But i want to show the
process of the colour changes. The problem may occured:
can i control the change process of the colour as I needed?
or is there other good methods?
Thanks a lot!

Have I answered this already ? If you want to change the text colour, the reliable way is to draw the text yourself and change the colour yourself. It's also the fastest.

Like I said, Get/SetPixel are methods of CDC.

There's your pointer to the bitmap data, just like I said. I suggest you write a Get/SetPixel method to work with this, it will be nice and fast then, although not as fast as iterating through in a tight loop.
Do you need to deal with paletised images ? How about 16 bit ? Both of those will be a pain, 24/32 bit is nice and easy.

NewB question of the day.
I am reading an article here at code project and it says to create my dialog type app and then add some controls next it states to:
"Using ClassWizard, create a CDialog-derived class for your dialog resource. Change the base class from CDialog to CNewDialog.."
I'm not sure how to do this from the ClassWizard.. Is it the same as going into the .h and .ccp files of my dialog and changing all occurrences of CDialog to CNewDialog?
Thanks,
Rob

While in the dialog editor, hold the ctrl key and double click the dialog (not on a control). It will invoke the class wizard for you and do the necessary things...
Hope this helps,
Bill
