Of course. it should be

if(cMailDate <big>>=</big> startDate && cMailDate <big>< </big>endDate)

Hi...

startDate =4/1/2008
endDate=4/3/2008
mailDates = 4/2/2008 7:26:33 pm..

my code is..

/////////////////////////////////////////////////////////
if (mailDate > firstDate && mailDate < secondDate)
{
AfxMessageBox("mails are between startDate and endDate");
}
else
{
AfxMessageBox("mails are not between startDate and endDate");
}
///////////////////////////////////////////////////////////

I should get the message as "mails are between stdate and enddate"

I am getting no mails.

thanking you

Sorry, I misunderstood the date formats you're using. if all your dates use the mm/dd/yyyy format (regardless about time) then you've to use always the US format, i.e.

COleDateTime startDate, endDate, mailDate;
DWORD lcidUS = MAKELCID( MAKELANGID( LANG_ENGLISH,SUBLANG_ENGLISH_US), SORT_DEFAULT);

startDate.ParseDateTime(_T("4/1/2008"), 0, lcidUS);
endDate.ParseDateTime(_T("4/3/2008"), 0, lcidUs);
mailDate.ParseDateTime(_T("4/2/2008 7:26:50 pm"), 0, lcidUS);

if ( mailDate >= startDate && mailDate < endDate)
{
  // mailDate is between startDate and endDate
}
else
{
  // mailDate is NOT between startDate and endDate
}

Hi All,
I am trying to display the total physical memory of my system. I used GlobalMemoryStatus() API. After rounding the value I get 447 MB. But, the system properties show the RAM as 448 MB. Does anyone have an idea why we get such a difference and how it could be overcome?

Thank you,
AJ

A little test on my system confirms the beahaviour you depicted. Then I found this [^], but I don't know if it is correct.

Visual Studio 6 had an Export Makefile option but as I am now using Visual Studio 2005 I cannot find this option, has it gone?

Does anyone know what is the method to generate a Make file if you wnat to port your code from Windows to a Unix platform?

Thnak you pallini.

still i am unable to solve my problem when I call my dll function

DebugError
-----------
Program:\Project\Test.exe
Module:
File:i386\chkespc.c
Line:42
The value of ESP was not properly saved across a function call.This is usually a result
of calling a function declared with no calling convention with a function pointer declared
with a different calling convention.

Try to post the code, on mondays my CPMRUs battery pack charge is pretty down.

by lot of R&D I find that This problem is occuring when I am calling
function with arguments i.e.
int function1(int arg)

when I callled the function without arguments no error is occuring
everything is fine i.e.
int function2();

Trioum

If it is a general issue, i.e. event an empty function give troubles then your calling convention is wrong.
I think you may (if you don't like to post the actual code), at least, post a simple test code that fails on your system.

ok I am sending some piece of code
in my dll my function as follows

extern "C" __declspec(dllexport) void function1();
extern "C" __declspec(dllexport) int function2(int index);

DllMain()
{

}

void function1()
{
// some code
}

int function2(int index)
{
int somevalue
somevalue =index;
return somevalue;

}

now on my applcation.exe

extern "C" __declspec(dllimport) void function1();
extern "C" __declspec(dllimport) int function2(int index);

//function1()
CMyDialog::OnButton()
{
function1();
//no error

}

//Now I called function2()
CMyDialog::OnButton()
{
function2(5);
// Debug error that I already post

}

Trioum

Why your function definitions don't match function declarations?
Should be

extern "C"
{
  __declspec(dllexport) int function2(int index)
  {
    int somevalue
    somevalue =index;
    return somevalue;
  }
}

I tried this sample.
But i am not getting error if i define just as
int function2(int index){ ...} why?

Because it is allowed.

Hello Everybody,

I too have a same problem.
[1]having a function ABC(arg1, arg2) in a dll that does not uses MFC.
[2]explicitly loading the dll (through LoadLibrary()).
[3]fetching the address of ABC() by using GetProcAddress(...) and storing it in appropriate function pointer.
[4]calling ABC() through the function pointer.

In DEBUG mode when control reaches the function pointer I get a MessageBox with following message :

The value of ESP was not properly saved across a function call.This is usually a result
of calling a function declared with no calling convention with a function pointer declared
with a different calling convention.

MessageBox does not appears in RELEASE mode.

Regards.

If it only happens in Debug mode and works correctly in Release then perhaps this compiler bug is causing it.

I believe it only effects VC2002 and VC2003.

Problem solved. !!! Cool | :cool:

!!!

I declared function pointer in following way :
typedef int (_stdcall *PFUN_ABC) (arg1, arg2);

PFUN_ABC pFunABC = (PFUN_ABC) GetProcAddress(hDLL, "ABC");
pFunABC(arg1, arg2);

Now works fine in DEBUG and RELEASE.

Thanks.
Regards.
