Hi, everyone.
Thank you for your help. But I am still missing the whole picture. Let me try to explain my confusion once more. I will describe the setup and I would need to know how to connect it
--- sdk.cpp --- compiles into sdk.lib
// defines global object
int& GetGlobal()
{
static int global_int=1;
return global_int;
}
--- sdk.h ---
extern "C" __declspec(dllimport)
int& GetGlobal();
--- plugin.cpp --- compiles into plugin.dll
#include "sdk.h"
// does something with a global object
extern "C" __declspec(dllexport)
void DoIt()
{
int& val=GetGlobal();
cout<

I am not really expecting an answer, but some clues...
Upon opening a socket, the socket opening doesn't fail. Yet, WSGetLastError() is returning a "file not found" error (a non winsock error).
Upon watching the file system (using FILEMON from SysInternals.com), I notice that my attempts to open a socket yield an attempt to load PSAPI.DLL from my current directory (every time).
This is the file not found, yet does not cause an socket error.
Questions:
1) Should I worry about this?
2) Why is winsock attempting to load PSAPI.DLL each time I create a socket?

I am currently working on a very important development project for my school, and a serious problem has occured. For some reason, DDX_Control() and GetDlgItem() will not work in CFormView, how am i sopposed to access control handles? I can't find another way around it, because i want to use a list control.

Don't you have member variables for the controls in your form ? use them directly.

They should work because I use them in my CFormView. Maybe you deleted something by mistake?
void CMyFormView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
DDX_Control(pDX, IDC_ICON_WINDOW, m_IconWindowCtrl);
DDX_Control(pDX, IDC_COMBO_ICONVIEW, m_ComboIconViewCtrl);
}
..
..
..
CListCtrl *pListCtrl = (CListCtrl *) GetDlgItem(IDC_ICON_WINDOW);

Why I can't use "\\servername\....\test.txt"?
When I use full path "c:\....\test.txt" it is fine.

Are you using CreateFile()? I got sick of that function for this reason and switched to the old <stdio.h> file functions. example:
FILE *file = fopen("\\servername\....\test.txt", "r");/*"r" means you're
reading the file........*/
if (file)
{
while (!feof(file)) /*while the file has not reached end of file*/
{
/*whatever........ go to cplusplus.com for a complete file function reference, type in "file functions" into the search field*/
}
fclose(file);//close the file
}
-- Steve

|

use "\\\\servername\\....\\test.txt"
and it will work

and you've tested the same filename string in a program like notepad?

i've written a snmp class that uses winsnmp, i'am facing a problem when quering a Win2000 or WinXP snmp agent, the response time is more than 10ms. i've seen applications that can do that much faster like my code, any suggenstions ??
Thank you!

SNMP is based on UDP and is considered extremely low priority. It's possible that the servers where the agents are running have higher priority tasks.

but this is with all servers/workstations, is there any way to boost the priortiy, do you have a glue how other programs might do that ?

yeateday i posted following Q:
visible spaces of a Tab ('\t') character equal to 6 space (' ') characters in CRichEditCtrl by default.
in visual c++ ide (not RichEdit), there is a setting which can change visible spaces of a Tab character to any space characters, i want to create a similar setting for our users.
//-------------------------------
a reply says to use SetParaFormat() with TABSTOPS flag.
i tested today, but it doesn't fit our case because it only formats max to 32 TABs in a line, if a line is very long, the format doesn't work fully.
how to solve the Q?
thx.
thanks in advance for any hints and help.

I'm building an app just as a personal toolbox for myself (may become cp article) and I'm looking for some suggestions. This app will need a database of some sort, and I'm leaning on using an embedded database rather then using MySQL or other service.
I've looked at the XML database options, but I don't like the idea of how large those files could potentially become. Anyone know of any free alternatives? Any database libs out there that I can embed into my app?
It doesn't have to be fully SQL complient, but I would like to be able to do simple joins at the bare minimum.
My code isn't buggy. Those are all fleatures.

SQLite seems popular and well supported, so this could be a good way to go. I don't like the fact that it is written in C and some other things are strange, but this is very personal stuff.
I'm working on app that uses pugXML (here on CP) as its database, and am very, very happy with this.

Can you embed that into your application or does it run as a seperate process?

not embedded, but small, practically free, and full SQL implementation including stored procedures.

Can anyone recommend a good FFT (Fast Fourier Transform) component that I can download? I simply want to pass it some data, and have it pop up a window displaying the FFT.
 Why is the phrase "It's none of my business" always followed by "BUT..."
