GetLocalTime was just what I needed.
Thank you much.

How can I calculate exactly the size of a string in Bold or Italic? GetTextExtent() apparently doesn't care about Bold and Italic settings.
Thanks.

Dear Sirs,
We need to create an application that supports Hebrew. Could anyone please give me an explanation on how use hebrew strings as resources and use them on a Visual C++ 6/MFC application? 
Thanks,

Hi I'm still newbie in VC++ and MFC. I'm writing an application, and need to create controls at runtime. For example, I need to create a button on a window every time I click on another previously created button.
I think that the biggest difficulty is mapping messages from those controls.. I have a CButton list to store the buttons, but how to tell the parent window to process every button messages??
Thanks for your time!

Determine which NIC is the one that is providing me with 'default' internet access?
For example, you open IE and go to google. Which NIC is it using? Currently i use gethostbyname() which does list all the IPs the machine has, but I can't figure out a way to tell which one is the active one.

What is the advantage of using VERIFY in the Release version . IT gets evaulated but doesnt terminate in case of the expression evaulates to FALSE .
|
|
|
|
|
The advantage is exactly that it *does* get evaluated. As you may know ASSERT does not.

The diagnostic message has the form

where name is the name of the source file and num is the line number of the assertion that failed in the source file.
In the release version of MFC, VERIFY evaluates the expression but does not print or interrupt the program. For example, if the expression is a function call, the call will be made.

If it doesnt not interrupt the Program why do you need it ?

You still want the code to execute and do something usefull in the Release version.
e.g VERIFY(CloseHandle(hHandle));
In DEBUG will assert if it fails to close the handle. In RELEASE you still want it to attempt to close the handle.
You could write it:
BOOL bOK = CloseHandle(hHandle));
ASSERT(bOK);

The simple answer is that when developers put a statement into an ASSERT while they are building code in debug versions, that statement can either be something that is used just to check a result or something that should execute AND check the result. Since many developers have a style of putting "real" code in their ASSERT statements, they found out that in the release build, those statements disappeared, as the ASSERT statements were ignored.
Thus the utility of VERIFY. If you use an ASSERT and only use a statement that tests a condition, then you are alright in both debug and release versions. If you put "real" code into an ASSERT and expect it to always execute in both debug and release versions, then you should use VERIFY instead.

Hello.
When I try to register my windows class using RegisterClassEx in my program I get an error which GetLastError tells me is error 120.
This apparently is:
This function is not supported on this system.
I find this confusing as an identical call in one of the programs in the SDK samples works fine? The only difference between the two is that my project is built using UNICODE. Could this affect the outcome of function calls with identical input?
This is the code:
LRESULT WINAPI MsgProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_DESTROY:
PostQuitMessage(0);
return 0;
case WM_PAINT:
case WM_TIMER:
case WM_GRAPHNOTIFY:
case WM_LBUTTONDOWN:
case WM_NEXTSCREEN:
case WM_STARTSCREEN:
HandleEvent(msg, wParam, lParam);
break;
case WM_DISPLAYCHANGE:
break;
case WM_CHAR:
{
if(wParam == VK_ESCAPE)
{
PostMessage(hWnd, WM_CLOSE, 0, 0);
}
else
{
PostMessage(hWnd, WM_NEXTSCREEN, 0, 0);
}
}
break;
}
return DefWindowProc(hWnd, msg, wParam, lParam);
}
HRESULT MakeWindow(HINSTANCE hInstance)
{
WNDCLASSEX wc = {sizeof(WNDCLASSEX),
CS_CLASSDC,
MsgProc,
0L,
GetModuleHandle(NULL),
NULL,
NULL,
NULL,
NULL,
L"Star Chart",
NULL};
RegisterClassEx(&wc);
}
... rest of windows code ...
How can it be that this identical code works fine in one project and not in the other?
Any ideas would be greatly appreciated because I have been at this for 6 hours now with no success...
If anybody needs to see any other code I would be glad to post it for you, I really just don't know what to try now...
edit:
I have now found that it is the GetModuleHandle() call that is producing the error? Can this be right?
Thanks in advance.

I think I managed to fix the problem, it was to do with the UNICODE preprocessor assignments. I don't think the functions like these assignments on 98.

Hi There
Does anyone know the struture of Outlook's .MSG file? I would like to extract the actual email data/attachment from the file.
Any ideas/pointers?
Thanks
|

An Outlook MSG is just a text file with source code of your mail.
Take a look at Mail Propierties - Details - Source (with Express).
If you know a little SMTP, you understand this code.
Cheers!

I have two dialog: one parent and one child.
Can I get the name (or the class) of the parent from the child?
thanks a lot
|
|
|
|

Really I don't Understand what do you want.
if You need to access the class member of parent from
child.
here is solution
In Child Dlg Class ,declare a var which is pointer to
Parent Class.
like this
CParentDlg *m_ParentDlg;
and Function
GetParentWnd(CParentDlg *m_Wnd)<br />
{<br />
m_ParentDlg=m_Wnd;<br />
}
now in Parent Class before calling the Child DLg
pass parent pointer
mChildDlg.GetParentWnd(this);
///call the domodal or showindow
and use m_ParentDlg in your Child class to access info from main parent Dlg
