Hi,
I am trying to write a proxy server but have run into a major problem. When
i try to read from a connected socket, it reads a couple of times and then
i get a connection reset from peer error in the errno var. Below is a
portion
of the code. Can anyone tell me what i am doing wrong?
if (write(sockfd, tempBuffer, sizeof tempBuffer) < 0)
errexit("echo write: %s\n", strerror(errno));
bytesReceived = read(sockfd, buf, sizeof buf);
if (write(fd, buf, sizeof buf) < 0)
{ errexit("echo write: %s\n", strerror(errno)); }
/* Is it a html page or image file */
headerResult = CheckHeader(buf);
if (headerResult == 0) /* html page */
{
while (bytesRead > 0)
{
bytesRead = read(sockfd, buf, sizeof buf);
if (write(fd, buf, sizeof buf) < 0)
{ errexit("echo write: %s\n", strerror(errno)); }
}
}
else
{
while ((bytesReceived < headerResult)&&(bytesRead > 0))
{
bytesRead = read(sockfd, buf, sizeof buf);
if (bytesRead < 0)
{ errexit("echo read: %s\n", strerror(errno)); }
bytesReceived = bytesReceived + bytesRead;
if (write(fd, buf, sizeof buf) < 0)
{ errexit("echo write: %s\n", strerror(errno)); }
}
}
shutdown(fd,1);
close(sockfd);

I’m a new user in Microsoft Visual C++ and I’m having a problem using SQL and stored procedure. I’m trying to create a new application using ODBC but the menu new stored procedure in DataView was disabled (not active), so I can’t create new procedures. For information, I use Pervasive.SQL Database.
So I was wondering whether anyone can tell me how to create new procedures and connect it to Visual C++, or are there any other way on using and executing SQL commands in Visual C++ ? And, can I have some example as well ?
Thank you for your help.

You might want to look at the docs for SQLExecDirect in the MSDN.

I want a class to have a member variable: PAVISTREAM *m_pavistream. Visual C++ does not share my viewpoint, and gives me many errors in the .h file:
syntax error : missing ';' before '*'
error C2501: 'PAVISTREAM' : missing storage-class or type specifiers
error C2501: 'm_pavistream' : missing storage-class or type specifiers
However, this works fine when I have the stream as a local variable. I'm not seeing what's wrong with this declaration. But then again, I don't know anything about the stream interface, so that could be my problem  Ideas?
thanks-
jake

Ditch the P in front of it and make it IAviStream * m_pAviStream. Also, don't forget to include VFW.h and link with VFW32.LIB

I am developing a program that resides in the system tray and want it to start hidden. But, I am having a slight problem. I know how to start with the main window hidden, that's the easy part. The part that I'm having trouble with is that when I start the program you can see the main window flash for a split second. I've tried removing WS_VISIBLE from the mainframe, SW_HIDE on m_pMainWnd in theApp class, adding WS_ICONIC to the mainframe style, but no go. Any help on this is greatly appreciated.

try to resize the window to zero by using the method call MoveWindow(...)
Good luck.

This is a wierd situation, and the solution is even wierder. I had to do this in an app a while ago and it took me a while to solve it.
Change this:
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();
To this:
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
And add this:
m_nCmdShow = SW_HIDE;
Right before you register your doc templates.
Hope this helps,
Frank

Thanks for the info. It surprisingly worked, somewhat. It does start hidden but when the listview refreshes the first time (2-3sec after startup) it flashes on screen. I don't see why the m_nCmdShow is any different than just passing it a simple SW_HIDE but it works better. Thanks.

Ok, after further analysis I've discovered the problem. After the view refreshes I have a function called ProcessReminders() and in it if a reminder has the dialog option set that means show the window. I call showwindow on the mainframe ((CMainFrame*)AfxGetMainWnd())
and pass it SW_SHOW which causes it to be shown but then the app hides it do to the SW_HIDE value of m_nCmdShow. If I comment out the showwindow line everything starts up how I want it to, but if a reminder is set to show the window I need it to show.

In the program of a recognizer, I intend to set up a timer each time I finish a stroke, if a new stroke begins before the time out then reset the timer, otherwise invoke a function to recognize the strokes and kill the timer. It seems the SetTimer() can not be linked to an object. Is there any one knows how to do it?

Hi forum,
Questions:
Does anyone know how to retrieve the actual column arrangement?
Does anyone know how to do the drag/drop-operation programmatically?
Underlying concept:
I know that with a cole like this you may enable Drag & Drop Column arrangement in a CListCtrl:
DWORD dwStyle = List.GetExtendedStyle() | LVS_EX_FULLROWSELECT |
| LVS_EX_HEADERDRAGDROP;
List.SetExtendedStyle(dwStyle);
This is not only cool, it even works fine (if IE4 is installed).
Now I would like to save the column arrangment for a give CListCtrl to enhance my user interface.... (see questions)
Thanks for any ideas!!!

1. Why this returns -1:
LONG xx=MCIWndOpenDialog(m_hMCIWnd), where hMCIWnd is a valid handle to the window created by calling:
m_hMCIWnd=MCIWndCreate(this->GetSafeHwnd(),
AfxGetInstanceHandle(), WS_VISIBLE|WS_CHILD|MCIWNDF_SHOWALL|MCIWNDF_NOTIFYSIZE|MCIWNDF_NOTIFYPOS,NULL);
No open dialog is shown.
2. Problem 2: Why "Open" selected from the popup menu lunched from the menu button doesn't do anything?

I'm using some code to attempt to open an AVI stream. The code compiles in visual c++, but gives me 3 fatal linking errors. These are the errors:
error LNK2001: unresolved external symbol _AVIStreamLength@4
error LNK2001: unresolved external symbol _AVIStreamReadFormat@16
error LNK2001: unresolved external symbol _AVIStreamOpenFromFileA@24
Debug/Capture.exe : fatal error LNK1120: 3 unresolved externals
The _AVI symbols are the names of the 3 functions I attempt to call - I assume they are in vfw.h, which I include. Ideas?
thanks-

Hi All,
How can I apply a shading to text in a Rich Edit Control?
CRichEditCtrl::SetBackgroundColor() changes the background
color for the entire CRichEditCtrl window, but how do I
just apply a shadding (or background color) to a selected
piece of text? Word is able to do it.
-Michael

You can set a background color for selected text using RichEdit 2.0 or later. Just pass CHARFORMAT2 structure to CRichEditCtrl::SetSelectionCharFormat and set crBackColor member to whatever you want.
