Hallo ,
I have the following problem: in a simple windows application "DynamicLoad.exe" a dll "DefExported.dll" is loaded. If I quit
the dll in InitInstance() with return FALSE instead of return TRUE,
I get memory leaks in the debugger at the end. Is it possible to change this?
Detected memory leaks!
Dumping objects ->
{96} client block at 0x0035A150, subtype c0, 64 bytes long.
a CDynLinkLibrary object at $0035A150, 64 bytes long
Object dump complete.
The program '[444] DynamicLoad.exe: Native' has exited with code 2 (0x2).
(Remark: FreeLibrary( hClcltr ) does not change anything, because return False results in 0 for HINSTANCE hClcltr=LoadLibrary("DefExported.dll").)
The problem is independent of the Microsoft Visual Studio Version (e.g. 6,7,8). The code to try out this, you can look at the page of "DLLs
are Simple! Part 3 By Mahmood Komeily" on this forum.
Just add in DefExported.cpp:
BOOL CDefExportedApp::InitInstance()
{
CWinApp::InitInstance();
return FALSE;
//return TRUE;
}
And in DefExported.h:
class CDefExportedApp : public CWinApp
{
public:
int Multiply(int ParOne,int ParTwo);
CDefExportedApp();
virtual BOOL InitInstance();
...
}

Check the dynamically allocated memory
Knock out 'T' from CAN'T ,
You 'CAN' if you think you 'CAN'

Thank yor for the fast answer.
I myself haven't forgotten to delete again new allocated memory.
Some memory allocations in the Microsoft code causes the leaks.
Maybe there exist work arounds: it's not necessary to quit the dll in
InitInstance(), it could be elsewhere. But in the dll it should be
decided that a loadlibrary-call returns with zero.
I thougth that this could be done best in InitInstance.

Which is a big indicator that you should probably start with something a little less ambitious. It's not my intention to burst your bubble, or thwart your desire to learn, but going about this project without even knowing where to start is akin to going up to the plate with two strikes against you (baseball analogy). It's going to be hard to pull it off.

Somewhat incomplete though. More like going to the plate "for the first time ever" already having two strikes.

Does the driver support two devices/cameras simultaneously?
My guess is a driver problem. Check the manufacturers web site.
|
|
|
|

no , it wasn't a problem of driver , I installed another driver ... nothing , and I know that another person solved it .

Can we write functions in a structure (struct) in C language. In C++, its possible. I have heard that we can write functions in C language using Function Pointers.. If anyone knows regarding this, please tell me.

C++-classes are really just structs with their members being private by default.
C-functions are not nested within structs.
But a C-struct can easily hold a function pointer - to a fuction defined and declared elsewhere.
In fact, this is very similar to what the C++-compiler does behind your back: Convert all functions of a class to global ones taking a first 'this' parameter defining all that distinguishes the instance from others of the same class.

Not sure what you mean but
to get the path of My Documents
use this registry key
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
Personal value has the complete path

Its something like this:
std::string GetApplicationDataPath()
{
std::auto_ptr<char> path( new char[MAX_PATH]);
const HRESULT result = ::SHGetFolderPath( NULL, CSIDL_APPDATA, NULL, SHGFP_TYPE_CURRENT, path.get());
if( result != S_OK)
return std::string();
else {
std::string s( path.get());
if( s.at( s.size()-1) != '\\')
s += '\\';
return s + _T("\\MyApp\\");
}
}
The CSIDL_APPDATA defines which of the plethora of system directories you want.
MSDN has them all.
