That's like asking what the fastest sorting algorithm is. It cannot be answered with the lack of information you've provided.

Help on closesocket()

Hi,

Does anyone know what the contents of the win32 api function closesocket(SOCKET s) are? As in, the exact code?

I need to use closesocket but I can't use the pre-written function because if I include winsock.h and such, the defines collide with too many of my other defines (I'm compiling and running the program under cygwin, but the problem is that the sockets are closed through windows, so I need closesocket to properly terminate them).

Thanks

Kelly Ryan

How are you opening the socket? Isn't the SOCKET parameter used by closesocket() the same one filled in by connect()? In any case, SOCKET is just an unsigned int.

use winsock2.h
and try WSACleanup() after to close everything
and also closesocket()

You can't replace closesocket(). The implementation is going to effect data stored in the TCP/IP stack that you don't have access to.

I believe you must solve that problem.

OnKeyUp doesnt work

Hi,

i have a dialog based app with a PretranslateMessage and a OnKeyUp Function that looks like this

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN)
{

switch (pMsg->wParam)
{
case VK_ESCAPE:
break;
....
}

return CDialog::PreTranslateMessage(pMsg);

}

void CMyDlg::OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags)
{
MessageBox ("Up");

CDialog::OnKeyUp(nChar, nRepCnt, nFlags);
}

But the Key up does not work ;
Exception : if i place it directly into the PretranslateMessage Function I can handle the event.

What is the problem ?

thanks

Load a new resource at runtime for my CFormview

24-Jun-04 4:52

So here is the problem ... i've been searching for days in the interet but found nothing that could help me. If someone knows the solution of my problem ...

So I wrote a multilanguage application with nice resource only dll's for the dialog boxes, menus ... It works fine libraries and resources are loaded, but there's a problem for two of them.

My application is made of 2 CFormview. It seems that the application loads once the resources for thoses two formviews during the CMainFrame::OnCreateClientfunction, and then nevermore.

Is there a possibility for a view to reload it's dialog resource at runtime ? I've been trying updateview, updatedate, invalidate ... Im'not sure that it is possible . Confused | :confused:

catching return key (VK_RETURN) with OnKeyDown

V.24-Jun-04 4:48

24-Jun-04 4:48

Hello,

It seems that in the app. where I'm working on, the default behaviour of OnKeyDown doesn't seem to catch the return key.

Can you modify this?
Can you modify this for 1 class and not for the entire app.?

tnx!

Hi ,
you need to overide the virtualfunction OnGetDlgCode, and then write the following line of code . Your Class must be derived from CWnd.

return CYourClass::OnGetDlgCode() | DLGC_WANTALLKEYS;

Hey,
tnx for your reply.
I did this:

<br />
UINT CtrlFlexArray::OnGetDlgCode(){<br />
	return CWnd::OnGetDlgCode() | DLGC_WANTALLKEYS;<br />
}			//end function OnGetDlgCode<br />

but the OnKeyDown still doesn't catch the return key.
Did I forgot something or did I do something wrong?
(NOTE: CtrlFlexArray is derived from CvsFlexArray and CvsFlexArray from CWnd, but I don't think this is the problem)

tnx!

Don't forget to add

ON_WM_GETDLGCODE()

to the message map of your class.

I want to install three hooks in a dll,one is WH_GETMESSAGE, two is WH_CBT,the other is WH_SHELL,the first hook is installed successfully but the second failed,codes as below:

BOOL __declspec(dllexport)__stdcall installhookCBT(HWND hCallProc)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
hCallHook=hCallProc;
hkbCBT=SetWindowsHookEx(WH_CBT,(HOOKPROC)CBTProc,hins,0);
if(NULL == hkbCBT)
{
DWORD d=GetLastError();
CString str;
str.Format("%d",d);
CFile file;
file.Open("D:\\1.txt",CFile::modeCreate|CFile::modeWrite);
file.Write(str,str.GetLength());
file.Close();

Maybe GetCurrentProcess, followed by OpenProcess, followed by GetModuleHandle with the process handle could do it. I haven't tried it, just guessing.

I hope this helps

GetModuleFileName(NULL, ...) is what you want to call from within the EXE.
