Is there any open source codes which can convert OpenGL rendering to HPGL format file?
|

Hi all,
I am registering a clipboard format as follows
UINT format = Registerclipboardformat(_T("FileName"));
then using the same format for setting the clipboard data
Setclipboarddata(format,hclipboarddata);
Now when i pass the file name to the handle, i could see in the memory location the path name is correct but after the execution of setclipboarddata command and after closing the clipboard when i see on the clipbook viewer, only drive letter is pasted.
Pl. answer to me ?
Thanks..

In VC++ 5.0 through 7.0 creating a static library is no big deal. Any projects created can find the libraries quite easily. Now I need to use a specific library in a VC++.Net environment and am a loss as to how to.
I am a teacher at a community college and basically teach c++ console applications and the texts that I use currently contain a copy of VC++ 6.0 but our classrooms are fixed with VC++.Net
Any help would be helpful.
I am a new member and hope to submit this particular library that provides a sequre method for fetching keyboard data for all primitive types, strings and dates for console applications which obviate the not-so-secure cin.

I have an include fiel enums.h that houses off enums used
enum WordDirection
{
Right = 0,
Down,
Diag_Down,
Diag_Up
};
I have a class 'A'
private:
int _iRow;
int _iCol;
bool _bHighlight;
std::vector<cletter> _arrLetters;
WordDirection _enumDirection;
TCHAR _sWord[16];
now adding the include into the cpp seems fine. but the compile flips in the enum line of the include file and says "error C2011: 'WordDirection' : 'enum' type redefinition"

I'm not an expert yet, but I play one at work. Yeah and here too.

your file is being included more than once, so it's trying to create the enum more than once ( I reckon ). If you're using precompiled headers ( stdafx.h ), try including it in there and nowhere else in your project. The other thing is to put an inclusion guard block around your code so it will only include once. I think #pragma once is all you need to do this, at the top of the file.

I need to close IE after starting IE with Createprocess. I am using ::PostMessage to try to close IE, but it is not working. I want to use Createprocess to start IE.
LPSTR szAPP = "c:\\progra~1\\intern~1\\iexplore.exe";
(CreateProcess(NULL,szAPP, NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo));
Sleep(10000);
hWnd=FindWindow(_T("IEFrame"), NULL);
::PostMessage(hWnd, WM_CLOSE, NULL, NULL);

Why dont u use ExitProcess API to close it.

Hi Mr Zak,
have you check for returned hWnd, may be it's NULL?
ZakAkili wrote:
::PostMessage(hWnd, WM_CLOSE, NULL, NULL);
Try WM_QUIT or pass ProcessInfo.hProcess returned from CreateProcess to TerminateProcess to closedown the IE

Try:
LPCSTR szAPP = "c:\\progra~1\\intern~1\\iexplore.exe";
CreateProcess(NULL,szAPP,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo));
Sleep(10000);
TerminateProcess(ProcessInfo.hProcess, 0);

Hi Guys.
I was reading through one of Mike's articles on sockets. And I just CANT
seems to wrap my brain around this one:
BYTE* bp = (BYTE*)(&dataLength) + sizeof(dataLength) - cbLeftToReceive;
I got this far:
(Its a Byte)(Called bp) = (Point to Byte)(&WHAT?!?!) + Something?
Okay now I'm lost.. I simply dont get the (&dataLength), now Datalength
is just an int, so what with the (&int) what does it do?
What does the syntax here mean?
Somebody please help me out!

Mike who?
Which article?

BYTE* bp ==> bp is a pointer to a BYTE
(BYTE*)(&dataLength) ==> casting the address of dataLength to a BYTE pointer
+ sizeof(dataLength) ==> advance the BYTE pointer to the byte just past the end of the memory occupied by datalength
- cbLeftToReceive; ==> bring the pointer back cbLeftToReceive bytes

Hello gurus,
I'd like to know how I can convert a DWORD (32 bits) value into a byte array of four bytes (32 bits)?
<br />
DWORD dwLength=(DWORD) file.GetLength();<br />
BYTE length[4];<br />
length contains the value dwLength as a 4 bytes array.
Thanks 
Best regards.

for (int i = 3; i >= 0; --i)
{
length[3 - i] = (dwLength & (0xff << (i * 8))) >> (i * 8);
}

DWORD dwLength=(DWORD) file.GetLength();
BYTE length[sizeof(DWORD)];
*(DWORD*) &length[0] = dwLength; Keep in mind that any code doing anything with the bytes will have to account for the endian type of the CPU.

Hi,
Thanks
Actually I've found the following way:
<br />
length[0]=HIBYTE(HIWORD(dwLength));<br />
length[1]=LOBYTE(HIWORD(dwLength));<br />
length[2]=HIBYTE(LOWORD(dwLength));<br />
length[3]=LOBYTE(LOWORD(dwLength));<br />
which also works

Or how about:
BYTE *pLength = (BYTE*)dwLength;
pLength[0] will equal the low byte (assuming an intel machine)
What do you need this for?

|

It works, but not the same way as my code in my earlier post. Yours forces big-endian order. Which isn't wrong per se, it's just something to be aware of. Don't try to write that byte array out to a file and read it back in as a DWORD, for example.

Hi
DWORD dwData=0x65A6;
BYTE arrDest[4];<br />
memcpy(arrDest,&dwData,sizeof(DWORD));<br />

Why? This is the method I've used in years past. I find it easier to read than a bunch of pointers ands casts.

I just write that thinking that people like it or not. I still use it in imaging programs, where image documents are large size and memory and speed are a constraint. It saves memory and helps out small programmers from the pointers nightmare, and the main point is it will save precious time as compare to for loops and memcpy operations etc.
