Errr.. Try perhaps the correct file name (I don't think "time" is a valid header file ). Perhaps "Time.h" will work better .

hi, it's possible to create a file in ram and accessing it with fopen/fread funcion?I've got some libraries that works on an mp3 file and I need them to work only on first 30 seconds, since they work on file stream and ends when EOF is reached I tought to create a file, copy first 30 seconds into and work in ram as it is a real file, but I don't know how... thanks

Check the memory mapped files

As Papa mentions check out memory mapped files - but you will need to use the Win32 read/write calls not fread/fwrite. You'll need to use ReadFile/WriteFile using the file handle that you get back from creating the mem mapped file. Check out CreateFileMapping (I was curious about this too ) and it's related functions on MSDN.

thanks to Papa amd Jim, but I've lib code that uses fread/fopen ( for portability iusse), so I can't use Win32 API, I think I'll copy the file into a new one on HD and then delete it after my works on it, thanks

How do use lib file. Do i just have to declare the lib name in the link tab. How do i get the function names that are exposed by the library??
|
|
|
|
|
Instead of putting it in the link tab, you can also use:
#pragma comment(lib, "libfile")
I suppose, if you have the DLL of the LIB file, you can view the dependencies from the "Depends" Visual Studio tool. It will list the functions exported.
Hope this helps.

Actually the project did not make any dll file....i have the complete code for the lib project. The project compiles ok no errors there. Only when i add the lib file to the project and try to call the global function for that lib then i get loads of unresolved symbols errors. Any ideas how to deal with this or what i am doing wrong here.
Thanks

The exported function is not being called correctly. Make sure C++'s name mangling is not biting you.

I'm curiuos about this too. Could you expound upon "name mangling" and how to avoid it?

Hey everybody,
I'm hoping more people can shed some light onto my font problem that I discussed in an earlier post.
Our application has a drawing area where the user can assign font type and size to a particular object. We're currently storing the logical units for the font, is this a bad thing? Will this display the same on all output devices (printer/screen etc)?
To me it seems like its better practise to store the actual point size, what's the dis/advantages of each and why? anyone?
Mike.

The only thing I would say is that dealing with fonts and a point size is usually much easier as you can get the actual point size for any given DC (be it printer or screen etc) using:
size = -MulDiv(pointSize, pDC->GetDeviceCaps(LOGPIXELSY), 72);
With logical coordinates you probably have to go through another translation first.
Also, it may depend on what DC mapping mode you are using.

Hello! i have a small problem
in my thread class (called CHilos) i declared as a member variable:
[CODE]
struct Param {
HWND *ventana;
CHilos *hilo;
} *param;[/CODE]
and in my thread 'begin' function i have:
[CODE]
void CHilos::Comenzar(LPVOID lParametro)
{
DWORD handle;
param->ventana = static_cast<hwnd *="">(lParametro);
param->hilo = this;
CreateThread(NULL,0,CHilos::ThreadProc,(LPVOID)param,0,&handle);
}
[/CODE]
and i get a runtime error in both param-> lines. In the createThread i used to pass this instead of param.
[CODE]CreateThread(NULL,0,CHilos::ThreadProc,(LPVOID)this,0,&handle);[/CODE]
what am i doing wrong?
thanks!

param = ??
param is a pointer to a struct Param, meaning its pointing to a struct param, but which one?
you do have something like this?
Param xParam = {0};
param = &xParam;
or maybe like this?
param = new Param;
or again like this?
param = (Param*) calloc (1, sizeof(Param));
in the last two case dont forget to delete (for new), free (for calloc) respectively when you are done using the param (thread end?).

Change:
<small>kfaday wrote:</small><br />
DWORD handle;<br />
param->ventana = static_cast(lParametro);<br />
param->hilo = this;
to:
DWORD handle;<br />
Param *pNewParam = (Param *) lParametro
Now you can access your members with pNewParam !

Try this, a simple one (MFC)
CTime t = CTime::GetCurrentTime();
struct tm* osTime;
osTime = t.GetLocalTm( NULL );
ASSERT( osTime->tm_mon == 2 );

i hope following will help u
CTime stime = CTime::GetCurrentTime();
CString s = stime.Format("%A, %B %d, %Y,%I:%M : %S :%p" );
AfxMessageBox(s);
chk it

Hi,
I try to use Script Control OCX in VC++ 7.0
i can do that.My problem is that i want to just compile script file by using AddCode method.But it is do compile and run script code.how can i disallow running script:
if (m_TargetEngine == CLSID_JScript)
{
m_ScriptControl.put_Language("JScript");
}
else
{
m_ScriptControl.put_Language("VBScript");
}
m_ScriptControl.put_State(0);
UINT column = 0;
UINT line = 0;
UINT Number;
CString Description;
CString Source;
CString Text;
try
{
//it is also do run but i dont want it do that
m_ScriptControl.AddCode(strCode);
}
catch (...)
{
LPDISPATCH lpdisp = m_ScriptControl.get_Error();
DISPID dispid;
OLECHAR* name = L"Column";
CComVariant result;
HRESULT hr = lpdisp->GetIDsOfNames(IID_NULL,&name,1,GetUserDefaultLCID(),&dispid);
DISPPARAMS params = {NULL,NULL,0,0};
hr = lpdisp->Invoke(dispid,IID_NULL,GetUserDefaultLCID(),DISPATCH_PROPERTYGET,¶ms,&result,NULL,NULL);
column = result.iVal;
name = L"Line";
