Does it work with Win32 or is it MFC only ?
Watched code never compiles.

Well the version I am using supports both Win32 and MFC. I think I downloaded it from one of the article comments several years back. Looks like the article was geared towards MFC.

You might want to remove the extraneous dot in those two URLs.

Hi DavidCrow,
Actually the trailing dot at the end of the URI is correct. It is called the root zone and is described in RFC-1034[^]. I come from a Unix backgound and have always written my URI with the DNS root zone. It is only recently within the last 2-3 years that I have noticed that certain browsers and webservers cannot handle the DNS root zone being present in the URI. I guess their 20 year old software engineers forgot to read RFC-1034.
Maybe I am just getting old. I guess the next thing that will dissapear will be the HTTP:// protocol indicator.
Best Wishes,

I've never seen such a dot used. I can't get those URLs to work with IE or FF.

Hi Friends,
I am using CListCtrl all images display on the first column, but i expect a output on second column,i don't know how to display on second column. please help me.Here is my sample code for first columns image dispaly.
Code..
m_SmallImg.Create(IDB_BITMAP2, 16, 1, RGB(255, 255, 255));
m_SmallImg1.Create(IDB_BITMAP1, 16, 1, RGB(255, 255, 255));
m_List->SetBkColor(RGB(66,66,66));
m_List->SetTextColor(RGB(255,255,255));
m_List->SetTextBkColor(RGB(66,66,66));
m_List->SetOutlineColor(RGB(255,0,0));
for(int i=0;i<=6;i++)
{
LVITEM lvItem;
lvItem.mask = LVIF_TEXT | LVIF_IMAGE;
lvItem.iItem = i;
lvItem.iSubItem = 0;
lvItem.iImage = i % 2;
lvItem.pszText = " sModelName ";
i = m_List->InsertItem(&lvItem);
m_List->SetItemText(i, 1, " TagName ");
m_List->SetItemText(i, 2, " UserName ");
m_List->SetItemText(i, 3, " Descddfgdfgfggdf ");

Hi,
I have a doubt regarding multimap::equal_range function for the following program.
int main ()
{
multimap<char,int> mymm;
multimap<char,int>::iterator it,it1,it2;
pair<multimap<char,int>::iterator,multimap<char,int>::iterator> ret;
mymm.insert(std::pair<const char,int>('a',10));
mymm.insert(std::pair<const char,int>('b',20));
mymm.insert(std::pair<const char,int>('b',30));
mymm.insert(std::pair<const char,int>('c',40));
mymm.insert(std::pair<const char,int>('b',50));
mymm.insert(std::pair<const char,int>('c',60));
mymm.insert(std::pair<const char,int>('d',70));
cout << "mymm contains:\n";
for (char ch='a'; ch<='d'; ch++)
{
cout << ch << " =>";
ret = mymm.equal_range(ch);
it1 = ret.first;
it2 = ret.second;
cout << (*it1).second << " " << (*it2).second << endl;
for (it=ret.first; it!=ret.second; ++it)
cout << " " << (*it).second;
cout << endl;
}
return 0;
}
It is giving following output:
mymm contains:
a =>10 20
10
b =>20 40
20 30 50
c =>40 70
40 60
d =>70 70
What I am not getting is the o/p for 'b'. I think it should be
b =>20 60
20 30 50
Please revert.
BR,
Akash

The output is correct, the map is orderd by the key.

Some suggestions:
- Use
typedefs:
typedef multimap<char,int> char2int;
typedef char2int::iterator char2map_it;
char2map mymm;
char2map_it it,it1,it2;
pair<char2map_it, char2map_it> ret;
There's no need to repeat long type names all over the place. One design decision should, if possible, be expressed in one place (or as few as possible): Now I can change from a map from chars to ints to a map from chars to std::strings by changing one line, for example.
- Use
make_pair from #include <utility>:
mymm.insert(make_pair('a', 10));
None of this is related to your question...

Which is fairly meaningless given that you've provided no context, or stated exactly what is happening. By "crash" do you mean an exception is thrown, an assertion is fired, or something else? Please elaborate. Have you used the debugger to narrow the problem down?

Locate the source file, and take a look at line 177 to see which condition is failing. That should get you started.

Hello guys,
I'm trying to write a funtion to read a simple bitmap, but I've encountered a serious problem.
As model I used the description of the bitmap file format from wikipedia http://en.wikipedia.org/wiki/BMP_file_format[^] and as far as I know this is definitely the correct format.
I also used the same 2x2 24-bit bitmap[^] to test my function, but except for the first value (the magic number or identifier) all other read values are wrong.
#include <stdint.h>
#include <stdio.h>
typedef uint8_t BYTE;
typedef uint16_t BYTE2;
typedef uint32_t BYTE4;
typedef struct BMP_FILE_HEADER
{
BYTE2 MagicNumber;
BYTE4 FileSize;
BYTE2 Reserved1;
BYTE2 Reserved2;
BYTE4 Offset;
} BMP_FILE_HEADER;
typedef struct BMP_INFO_HEADER
{
BYTE4 HeaderSize;
BYTE4 ImageWidth;
BYTE4 ImageHeight;
BYTE2 NumberOfColorPanels;
BYTE2 ColorDepth;
BYTE4 Compression;
BYTE4 ImageSize;
BYTE4 HorizontalResolution;
BYTE4 VerticalResolution;
BYTE4 NumberOfColors;
BYTE4 NumberOfImportantColors;
} BMP_INFO_HEADER;
typedef struct BITMAP
{
BMP_FILE_HEADER bmpFileHeader;
BMP_INFO_HEADER bmpInfoHeader;
BYTE* bmpData;
} BITMAP;
#define BI_RGB 0
#define BI_RLE8 1
#define BI_RLE4 2
#define BI_BITFIELDS 3
#define BI_JPEG 4
#define BI_PNG 5
BITMAP readbmp(const char* _pcFileName)
{
FILE* bmp = fopen(_pcFileName, "rb");
BITMAP bitmap;
fread(&bitmap.bmpFileHeader, sizeof(BMP_FILE_HEADER), 1, bmp);
fread(&bitmap.bmpInfoHeader, sizeof(BMP_INFO_HEADER), 1, bmp);
fseek(bmp, bitmap.bmpFileHeader.Offset, SEEK_SET);
bitmap.bmpData = (BYTE*)malloc(bitmap.bmpInfoHeader.ImageSize);
fread(bitmap.bmpData, bitmap.bmpInfoHeader.ImageSize, 1, bmp);
fclose(bmp);
return bitmap;
}
To test my function i wrote a short program, which reads the above mentioned bitmap.
#include <iostream>
#include "readbmp.h"
#define DBG(x) (cout << #x << "\t:\t" << (x) << endl)
using namespace std;
int main(void)
{
BITMAP myBmp;
myBmp = readbmp("..\\bmp24.bmp");
DBG(myBmp.bmpFileHeader.MagicNumber);
DBG(myBmp.bmpFileHeader.FileSize);
DBG(myBmp.bmpFileHeader.Reserved1);
DBG(myBmp.bmpFileHeader.Reserved2);
DBG(myBmp.bmpFileHeader.Offset);
DBG(myBmp.bmpInfoHeader.HeaderSize);
DBG(myBmp.bmpInfoHeader.ImageWidth);
DBG(myBmp.bmpInfoHeader.ImageHeight);
DBG(myBmp.bmpInfoHeader.NumberOfColorPanels);
DBG(myBmp.bmpInfoHeader.ColorDepth);
DBG(myBmp.bmpInfoHeader.Compression);
DBG(myBmp.bmpInfoHeader.ImageSize);
DBG(myBmp.bmpInfoHeader.HorizontalResolution);
DBG(myBmp.bmpInfoHeader.VerticalResolution);
DBG(myBmp.bmpInfoHeader.NumberOfColors);
DBG(myBmp.bmpInfoHeader.NumberOfImportantColors);
cin.get();
return 0;
}
This code just writes out the header informations as following:
myBmp.bmpFileHeader.MagicNumber : 19778
myBmp.bmpFileHeader.FileSize : 0
myBmp.bmpFileHeader.Reserved1 : 0
myBmp.bmpFileHeader.Reserved2 : 54
myBmp.bmpFileHeader.Offset : 2621440
myBmp.bmpInfoHeader.HeaderSize : 131072
myBmp.bmpInfoHeader.ImageWidth : 131072
myBmp.bmpInfoHeader.ImageHeight : 65536
myBmp.bmpInfoHeader.NumberOfColorPanels : 24
myBmp.bmpInfoHeader.ColorDepth : 0
myBmp.bmpInfoHeader.Compression : 0
myBmp.bmpInfoHeader.ImageSize : 247660544
myBmp.bmpInfoHeader.HorizontalResolution : 247660544
myBmp.bmpInfoHeader.VerticalResolution : 0
myBmp.bmpInfoHeader.NumberOfColors : 0
myBmp.bmpInfoHeader.NumberOfImportantColors : 0
What am I doing wrong? It looks as if the parameters are in a wrong order, even though I used the one described on wikipedia.
Thanks for your help.

This is because the compiler will add padding-zeros in the structure to align the different members on a specific boundary. You can read more about the subject here[^] (or google to find additional information).
To disable that, you have to pack your structure on a 1 byte boundary using #pragma pack(1). See here[^].
On the other hand, why are you writing the code to read a bitmap ? There are already quite some libraries which can do that, so why reinventing the wheel ? (unless for learning purpose, in which case it is understandable).
|
|
|
|
|
Learning purpose ... not really. I know that there are a lot of libraries out there, which can load bitmaps. Actually I was just bored to death and wanted to do something. And I wanted a bitmap structure/class which gives me full control over all parameters and single values.
Oh, and thanks, the parameters are now displayed correctly. There is just one thing I do not understand: The value which contains the image size is always 0x00.

It may be you won't need to use image-size, just width and height, and so don't need to worry too much about it. A quick search of (a limited amount of) code on my laptop that deals with bitmaps did not find it being used. Though Width and Height occur all the time as in a call to, for example, the Win32 function:
BitBlt(hDC,xDest,yDest,bmInfo.biWidth,bmInfo.biHeight,hDCMem,0,0,SRCCOPY);

|
|

Yeah, I think you're right. However, the image size would make memory allocation easier.

I am having a sample Console based application Test.dsw which uses .C files. The application start point is the file shown below.
//GLGMain.h
/*---------------------------------------------------------------------------
| This file defines platform-specific entry point and may be included when
| the generic GLG API is used.*/
#include "GlgApi.h"
#ifdef __cplusplus
extern "C" {
#endif
/* Prototype for GlgMain */
int GlgMain _G_PROTO(( int, char*[], GlgAppContext ));
#ifdef __cplusplus
}
#endif
#ifdef MS_WINDOWS
#include <windows.h>
/* MS Windows entry point. */
int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow )
{
GlgAppContext AppContext; GlgObject args_array; int rval; GlgLong argc;
char ** argv;
args_array = GlgParseArgs( "GlgToolkit", lpCmdLine, &argc, &argv );
AppContext = GlgInit( False, (GlgAppContext)hInstance, argc, argv );
rval = GlgMain( (int) argc, argv, AppContext );
GlgDropObject( args_array ); GlgTerminate(); return rval;
}
#else /* X Windows *//* X Windows entry point. */#ifdef _G_USE_PROTOTYPES
int main( int argc, char *argv[] )#elseint main( argc, argv ) int argc;
char *argv[];#endif{ return GlgMain( argc, argv, (GlgAppContext)0 );}
#endif
The main functionality of the application is present in the file diagramG.C.
I want to convert the application to MFC Based application and use the diagramG.C file in my application. When I tried to create a MFC EXE application and included the diagramG.C file in my project and started compiling its giving me errors. kindly advise.
Anyone kindly tell me the step by step procedure to use the diagramG.C file in my MFC based application and change the starting point of the application from int APIENTRY WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow ) to MFC starting point.
Thanks in advance

I would take the opposite route: let Visual Studio generate the MFC application skeleton for you and then add your files to it.

Please, read the posting guidelines before posting. When posting code, use the pre tags to format your code properly.
Now to your question: there's no magic way to convert from a console application to a MFC application. You'll need to understand how MFC works and refactor parts of your code. What has to be modified highly depends on your specific application, there's no generic way to do something like that.
So, if you never worked with MFC before, I strongly suggest you start by reading a good book on the subject, it will make you gain a lot of time in the near future.
