The size of the structure is 14 bytes.
I assume this is (8 for 2 floats + 2 for the short and 4 for the 4 bit fields)
I am after a size of 11 bytes.
Are they any settings that I have not made?

You do know that sizeof() cannot be used on bit fields, don't you?

If I use the following code:-
typedef struct<br />
{ <br />
unsigned short data1;<br />
float data5;<br />
float data6;<br />
unsigned short data7;<br />
}TEST1_101;<br />
#pragma pack()<br />
TEST1_101 message_data1;<br />
int sizeStruct1 = sizeof(message_data1);
I get size = 12 bytes, which I understand (8 for floats + 2 x 2 for shorts = 12 bytes. But why dont I get 12 for the following:-
typedef struct<br />
{ <br />
unsigned data1 : 4;<br />
unsigned data2 : 4;<br />
unsigned data3 : 4;<br />
unsigned data4 : 4;<br />
float data5;<br />
float data6;<br />
unsigned short data7;<br />
}TEST1_101;<br />
#pragma pack()<br />
TEST1_101 message_data1;<br />
int sizeStruct1 = sizeof(message_data1);

I hinted at the fact that you cannot use sizeof() with bit fields. Did you miss that earlier?

OK, yes I saw your post that stated that, but removed the bit fields and tried a few other things and then put back the bit fields.
I think the overlay works with the union, but the fact that a bug in my program and the sizeof() problem with bitfields led to confusion.
Thanks,

Hi, I'm having a problem with a dialog. I need my dialog box to recieve/intercept all keyboard events that go on inside, but I'm getting problems where only the controls are reciving the keyboard events. Presumably only the window with the focus can ever recieve keyboard message. My dialog simply does not recieive any OnChar, OnKeyDown, or OnSysChar events. So I implemented OnKillFocus in the dialog like so...
void CMyDialog::OnKillFocus(CWnd* pNewWnd)
{
CWnd::OnKillFocus(pNewWnd);
SetFocus();
}However this seems to make all my buttons totally unclickable! Does anyone have a solution to this at all?

You might want to try overriding PreTranslateMessage for your dialog.

Thaks a lot but there aren't examples for office 2003.
My problem is that when i select the wrapped class, the file msword*.h and msword*.cpp aren't created but in the project i find only files for single classes that i selected (Capplication.h,CDocments.h,....)
Understand you my problem? Thanks a lot and i hope you understand my english

Can you give me more details on what you are attempting to do? Are you trying to use a framework such as MFC or just plain Win32 API? Are you trying to use the #import statement?

I'm using MFC, and i tryed to use the #import but don't work.
I thing the biggest problem is my office version that is 2003. When i add the wrapped class (type library), there isn't file like msword*.h in my project but only a lot of new class for word (for example CApplication.h, CDocuments.h, CDocument0.h,......).
Undestand you my problem?
thanks

The article I suggested to you contains sample code to be used with visual studio 6 and I'm assuming you have VS.NET 2002 or 2003. You can still use the sample code with just some minor modifications.
To start with the 'Add Class' wizard generates a header file for each class rather than one file for the whole type library. This means you need to add an include statement for each class you use.
Next the class names have changed. What was _Application in Word2000 is now CApplication in Word2003 likewise _Documents has changed to CDocuments and _Document has changed to CDocument0. If you look at the header file names the class wizard adds to your project you can work it out.
Finally the function names have changed. For instance GetActiveDocument() has changed to get_ActiveDocument() and SetVisible() has changed to put_Visible(). In general the functions are now called get_'property name' to retrieve the value of a property or put_'property name' to set the value of a property.
If you would like a very basic VS.NET 2003 MFC dialog project that generates a word document I would be happy to send one to you.

I sent you the project a couple of days ago to the address you specified. Let me know if you need it sent to a different address. Alternatively if you have a small test project you would like me look at you can mail it to (steve . thresher @ ukonline . co . uk) remove the brakets and blanks.

hi, i want to know how i can get back the data from click event of the list control?
i received a these 2 pointers, (NMHDR *pNMHDR, LRESULT *pResult). i think i need to have a typecast to get back my data.
how can i get the position i click on the list so that i can get back my data from CListCtrl::GetItem() or CListCtrl::GetItemData()?
any help?
thanks?

You have to call HitTest() function to check which item of List Control is hit. After getting Handle to that item, you can do whatever you want.
You can find Articles here on CodeProject for this. Sorry, I am too tired to search for those. You have to do it yourself.
Imagine that you are creating a fabric of human destiny with the object of making men happy in the end, giving them peace and rest at last, but that it was essential and inevitable to torture to death only one tiny creature..and to found that edifice on its unavenged tears, would you consent to be the architect on those conditions? Tell me, and tell me the truth!

Try casting to LPNMLISTVIEW:
LPNMLISTVIEW p = (LPNMLISTVIEW) pNMHDR;

actually, how can u get this?
i can't get any hints from MSDN library.

Hi there,
I know that it's bad coding practice to have public data members but what if you have a private struct containing about 10 fields. If I create a public struct containing the exact same fields and set each field to something, can I pass that public struct as a parameter to the mutator method to set the private data members to?
Does this fall under poor coding practices category or is it an exception to the rule?
Thanks!

Take a look at NetUserGetInfo() using level 1. The USER_INFO_1 structure has a field called usri1_flags.
Then do something like
:
if ((usri1_flags & UF_ACCOUNTDISABLE) == UF_ACCOUNTDISABLE)
{
}
