strftime will probably do what you ask.

thanks for the reply!

this is what i use:

void CSimpleDlg::SetStartTime(SYSTEMTIME& stStart)
{
wchar_t* wcStartTime = new wchar_t[MAX_SIZE_STRING_TIME];
wcsftime(wcStartTime,MAX_SIZE_STRING_TIME,L"%H:%M:%S",&stStart);

}

i get a compilation error regarding last parameter should be of 'tm' struct.how do i convert from SYSTEMTIME to tm?

thanks again

you might also do it that way:

<br />
wchar_t* wcStartTime = new wchar_t[MAX_SIZE_STRING_TIME];<br />
swprintf(wcStartTime, "%i:%i:%i", stStart.wHour, stStart.wMinute, stStart.wSecond);<br />

The values in the SYSTEMTIME structure are in no particular format. It's up to you to format them into a variable. For example:

char str[32];<br />
SYSTEMTIME st;<br />
GetSystemTime(&st);<br />
sprintf(str, "%02u:%02u:%02u", st.wHour, st.wMinute, st.wSecond);

The WIN32 api has some powerful functions for formatting SYSTEMTIME vars. See GetDateFormat and GetTimeFormat in the docs.

Hello,
I have a problem ... I want to capture the desktop and save it in a 24Bit bitmap ... my desktop can be 256, 16bit or 32bit color.
How can I do that ? It works fine if the desktop is in 24bit ... but I want to convert a HBITMAP from 256, 16bit, 32bit to 24bit ... I hope I will not have to convert it manualy by saveing it byte by byte .... I hope there is something in windows that can take care of it ... because I saw 15Bit color and God knows many these types can be and I hope I don't have to take care of all... Please if anone can help me... !!! thanks !!!

Check out a class by PJ Naughter called CDibImage. It does conversion to 24bit. Excellent class. http://www.naughter.com/dibimage.html[^]

Hi
Recently I installed Visual Studio .NET for testing purposes, but kept Visual Studio 6 on my HDD. Now I uninstalled VS .NET and VS6 doesn't handle files like .dsw,.cpp,.h etc anymore. How do I restore the file associations with VC6 again?

regards

Either reinstall, or set the associations manually. VS6 doesn't include any tools for redoing the associations.

Ok thanks, seem like it's gonna be a lot of work. Do I lose my VC settings like colors, fonts, include/lib folders etc. if I reinstall?

Yeah, but you can backup that part of the registry first (just export to a .reg file, and import again after the install)

GetObjectsForNativeVariants

Anybody know how to use the Marshal.GetObjectsForNativeVariants function.I want to transfer the data from Unmanaged Win32 DLL to C# DLL.but the restriction is that I can only use IntPtr as passing param.
Like
Win32 DLL

I created One SafeArray
SAFEARRAY *pSA;
//Some code
pSA = SafeArrayCreate(VT_BSTR...);

SafeArrayPutElement(pSA...,String here );//safearray is full of BSTR Strings

then I called the C# DLL function
pData->ISetIntData((long)pSA);

And in C# DLL

public void ISetIntData(IntPtr Val)
{
Object[] MyObj=Marshal.GetObjectsForNativeVariants(Val,2);
String str=(String)MyObj[0];
MessageBox.Show(str);
//Here It is crashing...
}

Is this a right way Or I am doing some crazy Stuff?

Problem with serialization.

I created a class with serialzation support. But then I store class all Ok, but then I try to load class compilation don't pass. Copliler writes:

binary '>>' : no operator defined which takes a right-hand operand of type 'class SnytVolRelOrder *' (or there is no acceptable conversion);

Maybe anyboby knows that's the problem is ?

Sorry for my English.

You can't serialize this type. Only following types works:

CObject* | SIZE und CSize |float
----------------------------------------
WORD | CString | POINT und CPoint
DWORD | BYTE | RECT und CRect
double | LONG | CTime und CTimeSpan
int | COleCurrency | COleVariant
COleDateTime | COleDateTimeSpan

You must override Serialize for each class that you intend to serialize. The overridden Serialize must first call the Serialize function of its base class.

I've already done this. The problem is my class normaly loads but then i try to story compliter write an error.

SnytVolRelOrd ord; or SnytVolRelOrd *ord = new SnytVolRelOrd();
CArchive ar(...);
....
ar<<ord; <-----------ok.="" compiler="" passed="" this="" place

ar="">>ord;<------Comiler write an error.

Life is not a programm.

I have no idea, which kind of problem it is. But, if I serialize my own classes i call the serialize() Function. Like this in DocClass:

void CEmvDoc::Serialize(CArchive& ar)
{
if (ar.IsStoring())
{ // Save
m_tProjDate=CTime::GetCurrentTime();
ar << m_sProjName << m_tProjDate;
}
else
{ // Load
ar >> m_sProjName >> m_tProjDate;
}
m_oaInterfaces.Serialize(ar);
SetModifiedFlag(false);
}
