I was looking at the instruction posted on http://www.codeproject.com/miscctrl/mschart.asp
but i need an XY Scatter plot instead of Bar graph, and I have no idea how to use the m.chart.SetChartData() for XY plot. Can someone help me with some sample code on that please.. because I don't know how to separate the X and Y data...

with many many many thanks,

Making a compiler which produces EXE files

Hi.
I know how to write an interpreter which can execute a program written in my own language. I want to know how I can implement the functionality so that the program can be made an independent EXE file which will run without the need of an interpreter. (Just like the VC++ compiler&linker do).
Waiting 4 reply.

It's A LOT of work. First of all you need to produce assembly which of course should be machine-dependent, meaning that you should produce a different instruction set for each different machine. Assembly in x86 CISC architecture is quite chaotic. Then you either need to create a linker or use one that already works in order to make that assembly into binary code.
I 've tried that for the SPARC (RISC) architecture. In order to produce the proper assembly you really need to know a lot about the CPU architecture and read the manufacturer's manuals carefully.

Good luck should you try anything like that,

I think the easiest way to do that would be to generate code in an intermediate language, like C. Then you can compile and link using standard tools. In addition you'll take advantage of the optimization of the intermediate compiler that way.

I am facing problem in implementing edge detection for 24 bit BMP images.
The algorithm 3*3 mask works fine with 400*400 size image, but not with 800*600
the error message pops up as memory execess voilation .particularly it says memory is read only
If anyone knows how to implement the above please write to me ASAP.

where is gpedit.h?

Hello

I am trying to make a program that tells me what the local machine name is?

I use GetMachineName() function but it says that it needs gpedit.h and it is not on my box. So where can I find it? I searched google and nothing.

You have to get a newer PSDK to get that file. It did not come VC6. It is in the Feb 2003 PSDK (the latest one I have with VC6) and it came with VC7.0.

How about using GetComputerName() or GetComputerNameEx() instead?

My install of VS 2003 has the file in

Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include

I'm guessing an updated platform SDK installed it.

Decimal precision problem?

I have tried to code a pi-calculation program (gauss-method), but I can´t get enought decimals on it. I tried to install apfloat, but I just got some weird error messages and install won´t succeed. Even the author of apfloat couldn´t figure it out, why I´m getting them.

Is there some "easier" way to get more decimals (or even some other way)? Few million should be enought for a while Smile | :)

Just kidding...million is enought at the moment.

CreateThread() problem, need help

fklldsvs1-Jan-05 9:25

I am trying to port some WinCE code to VC++. I am having difficulty initializing a new thread with CreateThread().

WinCE:

WinCE_Program.h
DWORD NewThread(LPVOID);
HANDLE hNewThread;

WinCE_Program.c
{
hNewThread = CreateThread(NULL,0,NewThread,0,0,&dwThreadID);
}

The above works fine for WinCE.

If I use this code for VC++ 5.0, I get an compiler error message:
"cannot convert parameter 3 from unsigned long (void *) to unsigned long (_stdcall *) (void *)"

What do I need to do to correct this?

Thanks

Read the error message Wink | ;)

You're passing a function with the signature unsigned long (*)(void*) but CreateThread() expects the signature unsigned long (_stdcall *)(void*). So you need to add the __stdcall calling convention to your callback. The usual way of doing this is with the CALLBACK or WINAPI macro (which you'll see in the ThreadProc help page).

Re: who knows pascal??

Ravi Bhavnani1-Jan-05 5:13

In Pascal, the semicolon is used to separate (not terminate) statements. A separator is required at the end of the statement, unless the statement is followed by another separator (i.e. a block terminator like end or until).

The following code fragments are both valid:

if (someCondition())
   then
     begin
       y = 0;  { semicolon required }
       x := 1  { semicolon optional because next token is "end" }
     end;

if (someCondition())
   then
     begin
       y := 0;
       x := 1;
     end;

Since it doesn't hurt to always separate statements with a semicolon, it's best to just always use it (as in C).
