and are you talking about send files or just communcating...?
|
|
|
|
|
//basic send and recieve is...
#include <string>
#include <winsock2>
#pragma comment(lib,"ws2_32")
WSAData wsaData;
WORD wVersionRequested;
wVersionRequested=MAKEWORD(2, 2);
WSAStartup( wVersionRequested, &wsaData );
std::string rawcmd;
SOCKET communcationsock;
SOCKET ListenSocket;
SOCKADDR_IN service;
ListenSocket = socket(AF_INET, SOCK_STREAM, 0);
service.sin_family = AF_INET;
service.sin_addr.s_addr = INADDR_ANY;
service.sin_port = htons(21);
if (bind( ListenSocket, (SOCKADDR*) &service, sizeof(service)) == SOCKET_ERROR) {
printf("bind() failed.\n");
}
listen( ListenSocket, 1 );
communcationsock=SOCKET_ERROR;
while(communcationsock == SOCKET_ERROR) {
communcationsock = accept( ListenSocket, NULL, NULL);
}
bytesRecv = recv( communcationsock, CMD, 128, 0 );
rawcmd.assign(CMD, bytesRecv);
if(rawcmd=="..."){
char onconn[128]="Can You Hear Me\r\n";
send( communcationsock, onconn, strlen(onconn), 0 );
}
//Basicallly you have to open up a socket for communication.. then you can open up //another sock separately and send files using the same principal.

Hey,
I'm trying to make a move from VB.NET over to C++ (Visual Studio 2003). I'm not new to programming, just programming in C++. I've read through about 10 tutorials over the last week or so and none of them explain how to do graphic stuff. I need to essentially recreate the GUI from my VB.NET application where it colors in defined regions and has drag and drop that knows when you drag something onto that specified region.
Is this possible? (obviously it's possible, but if it takes writing like 100 different function and classes and libraries, it's not really possible).
If anyone can suggest a starting point, I'd be very greatful.
Thanks all!
Mike

I am curious, why do you "need to" do that?

Umm... I'm moving the game from vb.net to c++ so I need an interface I suppose. It has to be drag & drop and has to be able to have colored in regions because that's how the game is played. I'm not sure what you're getting at? /

No, I am not sure what you are getting at. In your first post you said you "need to" I wondered why you needed to port the application to C++ from VB.NET.
The C++ environment supports .NET development so the port from VB.NET to C++.NET should be a 1 to 1 port. The .NET class library is exactly the same in VC++.NET as in VB.NET.

I know the number of lines that I have in my document, but the number of pages will depend on the font size, spacing, margins, etc. Is there an easy way to determine the number of pages? A quick comment or code summary with a reference to relavent sample code would be greatly appreciated. Thank you.

You should be able to calculate the number of pages inside OnBeginPrinting(). Call pDC->GetDeviceCaps(VERTSIZE) to find the vertical height of the paper in mm. You should then be able to calculate the number of pages from the number of lines, the font size and the page size. Here is what I do...
void CActionManView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
m_nHeight = 32; Font size
m_normalFont.CreateFont(m_nHeight, 0, 0, 0, FW_NORMAL, FALSE, FALSE, 0, ANSI_CHARSET,
OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,
DEFAULT_PITCH | FF_DONTCARE,"Ariel");
pDC->SetMapMode(MM_LOMETRIC); // 0.1mm units
int height = pDC->GetDeviceCaps(VERTSIZE) * 10; // Get size of page in mm and scal to 0.1mm units
m_nItemsPerPage = height / m_nHeight; // Calculate items per page
m_nItemsPerPage -= 10; // Allow for header/footer
unsigned int nNumPages = (GetPrintableTaskCount() /m_nItemsPerPage)+ 1;
pInfo->SetMaxPage(nNumPages);
m_nPrintItemIndex = 0;
}
Hope this helps.

cannot convert parameter 1 from 'class CString' to 'const char *'

use ttol.
CString str = _T("12345");
long l = ttol(str);
When UNICODE is defined, TCHAR (which is what CString uses) is defined as wchar_t (which is typedef'd as unsigned short). When it is not defined, TCHAR is defined as char. Make sure you use the t-methods when dealing with strings and UNICODE builds.

If you are using CString, make sure you use the _ttol method. If you are building with UNICODE turned on, atol/atoi will give you conversion errors.

Thanks for reply..yeah i have checked,when i build in debug mode i did not get that error,when i build in UNICODE,i got the error...
One more Error...
error C2664:'CollateNoCase' : cannot convert parameter 1 from 'char [5]' to 'const unsigned short *'
how to over come this error pls
thanks in before

Use the t-methods and TCHAR instead of the standard methods and char.

Hello,
I want to change the visibility of a push button, such that given a certain condition, the button is not visible at all (I don't mean just greyed out, I mean completely gone). What method do I use to control this?
Thank you.

::ShowWindow(SW_SHOW/SW_HIDE) or CWnd::ShowWindow(SW_SHOW/SW_HIDE) depending on if you are using Win32 or MFC.

I have an SDI application that has inherited CFormView as the base class. When the application was created it disabled all print functionality. I would like to be able to add this functionality. I know that I can add virtual functions but I am confused on what to put in these functions. I would like to print the application as it looks. Is that even possible? Any help would be great.
thanks,
adam

there are a few things that I don't understand in this code example. one i don't know what the variable m_dib is and where it came from. I also don't understand GDIUtil::GrabDIB function call. I get an error that the compiler doesn't know that it exist. any help would be great.
thanks

The author of the article used someone else's code (the GDIUtil class/namespace). Click on the link he provides in the article for more information.
