hi capricious_001

you can check http://www.codeproject.com/internet/csmtpconn.asp[^]

The Program is not through Telnet but it's a simple implementation to send mails using SMTP.

Hope it helps....

Hey quickdeveloper,

Thats a really neat program, and I'm actually looking at using that. What I really like is that its REALLY clean and well documented... meaning it took me only a few seconds to realize whats going on and i'm a newbie programmer.

The only problem is that you need to have access to an SMTP server that has no authentication whatsoever and doesnt use SSL.

lol you wouldnt know of any SMTP Servers that don't have any authentication or use SSL would you? :P

Thanks for the script btw Smile | :)

Most likely you've got recursion that is too deep. i.e.

void Foo()
{
     Foo();
}

Thanks Steve. It looks like I solved the problem by reduce the size of arrays in the program.

However, now I got "unhandled exception, 0xC0000005 access violation"

Please help thanks

When I print (using the break points)the array value, e.g. data[1022] I got -1.#INDO and the error message says: Unhandled exception in Data_proc.exe:0xC0000005: Access violation

The function code where the message is generated:

void CBlast_vib_procDlg::complexFFT(float data[],unsigned int &nn,int &isign)
-> {

The data[1022] is within the range of the array defination.

First, I create a bmp control on a Dialog, and set its ID to ID_MYBMP
second, I creat a member variable for the bmp control as m_mybmp;
third, I import a bmp file into the resource and name it IDB_MYBMP;
forth, I add following code to the funcion OnInitDialog()

BOOL CMyDlg::OnInitDialog() 
{
    CDialog::OnInitDialog();

    CBitmap bmp;
    bmp.LoadBitmap(IDB_MYBMP);
    m_mybmp.SetBitmap((HBITMAP)bmp);
}

Thank you very much!!!

I'd check if bmp contains a bitmap, in the debugger. One way is just to call GetWidth and see what you get back. Then you can focus on the bitmap control as a possible source of the problem.

Try the following code as it works in my application for same

CBitmap bmp;
     bmp.LoadBitmap(MAKEINTRESOURCE(IDB_SCHEDULE));
     m_Schedule.SetBitmap(bmp);
     bmp.Detach();

Hope it works for you

Hi ewighell
Do you set Bitmap(false) to true in property window from control?

The bitmap is destroyed when your CBitmap object goes out of scope. Make the CBitmap a member of your dialog class.

Hello,

I have a simple application where I try to display a dialog with a timer. It builds fine in the debug mode but not in the release mode. This is the error I get:

Make sure that the OnNotifyPowerOnTime function implementation is not enclosed within a #ifdef DEBUG section (there is one around the Dump( ) and AssertValid( ) functions, it may have ended up inside that section).

Hi dabs,

You were right. The function was enclosed within a #ifdef _DEBUG section. I moved the function outside the #ifdef _DEBUG and recompiled and everything is fine. Thanks for your help.

Hi,

Do not need the actual parameter for WPARAM. As long as the defn. matches the decl. My code compiles fine in both the release (after the fix, thanks to dabs) and debug mode.

Win 32 DLL using .NET

Does it make sense to use the .NET framework to develop a Win32 DLL that will reuse a lot of code from another project that uses MFC classes . I am going to stick to coding language as C++

If so what kind of solution ( project / language) is preferred ?

Engineering is the effort !

Sounds like you need to host an instance of the WebBrowser control. It's an ActiveX control so you'll to use MFC or ATL unless you want to implement the hosting code yourself (you almost certainly don't).

Thanks for the tip... I'd like to know if you think I should use (MFC or ATL) as I'm trying to read .html files on disk and display them within a screensaver. What is the easiest way of accomplishing this goal? I have to use the method declaration that follows, and all I have to use is a handle to the screensaver window (hWnd):

LRESULT WINAPI ScreenSaverProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

socket question

nahitan11-Apr-06 11:02

11-Apr-06 11:02

I have to send some data as XML format to two different places right now I send all the data to one location through a socket and I need to create another socket to send some other data to second location as follow:

If (data1)
send to LOC1
else
send to LOC2

and this LOC1 connection should always be open
at this point I have the socket and connection to LOC2

Please help me to know how to make the second connection to LOC1 for the first connection to LOC2 the code uses CfgRemoteAddr=127.0.0.1 and some local port: local 1222 and remote 1223.
as follow:
if( hCfg->CfgApiSocket->CfgTCP )
.
.
..
if( !hSocket->sSend( hCfg->CfgApiSocket->CfgRemoteAddr, 0, ( LPSTR )XMLString, XMLSize ))
{
//Socket::sSend( LPSTR Address, INT PortId, LPSTR txBuff, INT txBuffSize )
tmpVar = 0;
memset( Buff, '\0', MAX_LOADSTRING );
tmpVar = hSocket->GetError(( LPSTR )Buff );
LogError( "WEAPIClass", "InSockProcess", "Error sSend Socket: %d, %s", tmpVar, Buff );
LinkStatus( IPC_LINK_DOWN, 0, NULL, 0 );
}
else
{

LogAppDiag( LOGGER_INBOUND_DIAG, XMLString, XMLSize, LOG_FORMAT_ASCII );
}

Thanks for any idea

Memory Leak using Bounds checker

act_x11-Apr-06 10:11

act_x

11-Apr-06 10:11

for pointer variables defined globally say CmemObject *pMem = NULL

For a class CMyClass

CMyClass::Init()
{
pMem = new CMemObject();

}

CMyClass :: ~CMyClass()
{
if(pMem)
{
delete pMem;
pMem = NULL ;
}

}

Still shows a leak where the new operator is called .
Is it safe to ignore this error as I am finally de allocating it ?

Are you sure the destructor for CMyClass is getting called AND pMem is not set to NULL somewhere else?
