Okay, so WMI seems pretty neat, until you figure out what it takes to get it installed if it is not already on a system. Just a word of warning before running off to depend upon it.

using multiple-language resource

I wrote a resource script with menu resources duplicated on several languages.
MSDN states that I can control loading appropriate version of resource using
SetThreadLocale() call, but this way doesn't work. Operating system always
loads English version of menus in spite of what thread locale I'm using. Can
you tell me what's wrong? I'm working with Windows XP SP1.

but it resources loaded in English. Dont know why?

Hi,

I use a thread in my app and in one portion of the code, the thread call another class. This class trie to pop up a window but get's a handle of 0x0000. Look like the Create or CreateIndirect fails.....

<br />
CWaitDlg *w=new  CWaitDlg ("","Please Wait"); //<-- this will return a 0x0000<br />
w->Create (IDD_WAIT);   <br />
w->ShowWindow (SW_SHOWNORMAL);<br />
<br />

The handle will always be 0 until you actually create the window.

You are right.

Is the thread that creates this based on a UI type thread or a background worker thread? If you are using MFC (which it appears), this is very important, as you should only create UI elements with a UI thread. See AfxBeginThread() in the Docs for more info.

onwards and upwards...

memory allocation

3-Jun-04 4:42

Hi everybody,

I would like to create a function which could allocate memory for any of pointer of pointer declared.
In my class C, i consider 2 pointers of pointers : **p and **q ( declared as public in class C), i would like to create a function AllocMemPointerOfPointer, which takes 3 input : RowSize, ColSize and Pointer. The function doesn't return value. It just allocate memory for Pointer, which is a pointer on RowSize pointers of any type .
How could i do that without allocate memory to a "copy" of Pointer ?

I hope my question is clear ! if not, feel free to ask me more informations !

Thanks in advance for your answers

Maybe you should make your modal dialog window have the desktop as its parent?
Try calling GetDesktopWindow() and use the returned handle for the parent of the modal dialog and see if that helps.

Hi!
I am trying to use the registry with win32 api c++.
But I have difficulties using the RegQueryValue functions.
I found some examples on the net but they all use CString and I cant use it because I dont write in MFC...
Can someone write an example? ( if possible the whole thing how to get a value?)
Thanks in advance!

Well... I am a beginner ...

TCHAR tszProductName[128];
DWORD dwBufSize = 128;

RegOpenKeyEx(HKEY_LOCAL_MACHINE, _T("Software\\Microsoft\\Windows\\CurrentVersion"), 0, KEY_READ, &hKey);
RegQueryValueEx(hKey, _T("ProductName"), NULL, REG_SZ, (LPBYTE)tszProductName, &dwBufSize);
RegCloseKey(hKey);

printf("Windows Product Name: ");
printf(tszProductName);

Hope that helps Big Grin | :-D

There are plenty of MSDN examples that do not use MFC. Here's but one:

    HKEY hKey;
    TCHAR szProductType[MY_BUFSIZE];
    DWORD dwBufLen = MY_BUFSIZE;
    LONG lRet;
 
    if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,
        TEXT("SYSTEM\\CurrentControlSet\\Control\\ProductOptions"),

                    KEY_QUERY_VALUE,
                    &hKey) != ERROR_SUCCESS) return RTN_ERROR;
 
    lRet = RegQueryValueEx(hKey,

                    (LPBYTE)szProductType,
                    &dwBufLen);
 
    RegCloseKey(hKey);

casting a vector

Jerome Conus3-Jun-04 2:33

Jerome Conus

3-Jun-04 2:33

Hi !

I have a vector of objects of class B. Class B is derived from class A :
A function in my application is asking for a vector of class A objects.
I want to pass my vector of B objects (which I guess should be possible because B objects are A objects, thus a vector of B objects if also a vector of A objects).

Here is a snippet of what I tried :

class A;
class B : public A;

void foo(std::vector<const A>& vect)
{
   //...
}

void main()
{
   std::vector<const B> MyVect;
   MyVect.push_back(new B);
   foo(MyVect);
}

I get a compile error, telling me that it's not possible to convert std::vector<const B> to std::vector<const A>.

How can I solve this ?

Thanks !
Jerome

cgott3-Jun-04 3:07

Hi Jerome

This cast can't be possible because std::vector< const A > and std::vector< const B > isn't the same class. I think you can do a template function like:

// file foo.h

template< class _T >
inline void foo( std::vector< const _T > &rVector )
{
// in your case you can do
const A &rEntry = ( const A& ) rVector[ nIndex ];
...
...
}

The compiler creates now two methods like:
inline void foo( std::vector< const A > &rVector )
{
const A &rEntry = ( const A& ) rVector[ nIndex ];
...
...
}
and
inline void foo( std::vector< const B > &rVector )
{
const A &rEntry = ( const A& ) rVector[ nIndex ];
...
...
}

The classes need to be derived from the same parent:

class C<br />
{<br />
};<br />
<br />
class A : public C<br />
{<br />
};<br />
<br />
class B : public C<br />
{<br />
};

And then you can have:

std::vector<C *>

And store A's and B's
