As a last question about this subject when I wrote:
#include "atlimage.h"
It gave an error as:
Cannot open include file: 'AtlImage.h': No such file or directory
Is the error means that CImage is not supported by Visual C++ 6? Or is there anything that can I do about that problem?
Thanks again

CImage wraps Windows GDI/GDI+ APIs which are all available for you to use.
The very simplest way I know to load and display a JPEG image is to use GDI+...
Gdiplus::Bitmap MyBitmap(L"C:\\test.jpg", FALSE);
Gdiplus::Graphics MyGraphics(hwnd);
MyGraphics.DrawImage(&MyBitmap, 0, 0, MyBitmap.GetWidth(), MyBitmap.GetHeight());

I see that CImage is not supported by Visual c++ 6.I want to ask a basic question; Can we add the CImage libraries to Visual C++ 6 manually.If it is possible how can we do that.

Hello..
I want to do NOT operation..but i here output is wrong..
<br />
main()<br />
{<br />
unsigned int Value=4; <br />
<br />
Value = ~ Value; <br />
<br />
}<br />
but my output is 4294967291 insted of 251.
Please help me out..
Thanks

If you only want to use 8 bits, you need to use unsigned char. Int is 32 bit longs, so you get FFFFFFFB when you do the NOT operation.

Actually:
unsigned int Value = 4;
Value = ~Value;

Actually The output (4294967291 = 0xFFFFFFFB) is correct (your assumptions are wrong) because the unsigned int type is 4-bytes wide:
HEX: ~0x00000004 =
0xFFFFFFFB
BINARY: ~0000 0000 0000 0000 0000 0000 0000 0100 =
1111 1111 1111 1111 1111 1111 1111 1011
if you want to obtain 251 then use the unsigned char type:
unsigned char Value;
Value = 4;
Value = ~ Value;

not very sure abt this.. bt i guess that if u wanna arrive at 251 ie. -5 (sign extended), u gotta use short int or int instead of unsigned int.
hope this helps

This is wrong. An integer is coded on 4 bytes, not on 1 byte, so it is 00000000 00000000 00000000 00000100 instead. Try to invert it, and you'll see that you will get 4294967291.
Replace the unsigned int by an unsigned char if you want to work on 1 byte.

Hi,
You are using unsigned int it is 32 bits long for 32 bit processer, and or depending on your compiler.
hence ~value is 0xFFFFFFFB not 0x000000FB,
if you really want 8bits of data use unsigned char instead.

Hello all
i have problem that when i'm input a character in emp_no field the program end or exit
i want that when i input number the program accept it and when i input character display me message that is wrong input and return to input number again
i used isdigit function but i want to return input again if the input not number
and Thank's For All

<br />
public:
void set_emp_no(int no)<br />

goto Begin;
And You think you get away with that? You can make this a
while(1) {
...
} loop.
if( isdigit( no)) could be changed to
if( <code>!</code>isdigit( no)) {
...complain about error here...
} and the isalpha could subsequently be dropped.
Failure is not an option - it's built right in.

The variable no needs to be changed to a string or a char[]. Then you can loop through each character to determine if it is a digit or not.

Hey guys, im taking some old code from my company and trying to make a library since the origional was about 20,000 lines of code with GIANT switch statement in each method.
any how, ive checked MSDN, and no one here(the 3 developers for release software are 23, 24, and 22, all straight out of college)
so the statements:
BOOL APIENTRY DllMain( HINSTANCE hModule, <br />
DWORD ul_reason_for_call, <br />
LPVOID lpReserved<br />
)<br />
{<br />
switch (ul_reason_for_call)<br />
{<br />
case DLL_PROCESS_ATTACH:<br />
case DLL_THREAD_ATTACH:<br />
case DLL_THREAD_DETACH:<br />
case DLL_PROCESS_DETACH:<br />
CGeneratePrinterCommands::_CGeneratePrinterCommandsHandle = hModule;<br />
break;<br />
}<br />
return TRUE;<br />
}<br />
<br />
temp = LoadResource(_CGeneratePrinterCommandsHandle, FindResource(_CGeneratePrinterCommandsHandle, MAKEINTRESOURCE(IDR_R800_XFER_M), _TEXT("HEXSTRING")));
cam anyone explain whats going on here regarding the _CGeneratePrinterCommandsHandle?

Hi,
_CGeneratePrinterCommandsHandle is storing the hModule,
which is the handle to the instance of the dll file, it contains
some resource data of type HEXSTRING and id IDR_R800_XFER_M.
The resource data is fetched to the global memory temp.

For my job I have designed a particular scripting language, that's ok, and it works fine.
But now I want to make a program to help write these scripts, so I thought in a SDI application with a RichEditView, and I want to add some intellisense features, like any program enviroment you can find these days, so my question is simple.
Could you someone point me, maybe, an article or something like that that talk about this kind of feature?.
I don't know if I have explained well, I would like my program be able to show ie a list with the script keywords while someone is writing. How could I do that?.
Thank you.
Demian.

i have tried the 2 steps of Keith's Rule guide
(
Last Resorts
Debugging in Release Mode
and
Making Debug Mode more like Release Mode
}
althought could fix it (or better didnt know where to look to fix the problem)

Hi all:
Yesterday I asked about dialog UI paint problem in which when the dialog overlapped with another window the dialog's UI got different kinds of trailing white strips. Today the problem solved accidentally in which DefWindowProc didn't get called once I finishing paint the dialog customarily, the modification was just a simple substitution from "break" to "return 1". For a hindsight, I know the rough idea behind this, I should have handled the painting by myself solely instead of let system handle it again, but I don't know what DefWindowProc done when I've painted the dialog made the dialog graffitified.
