Hey Guys
I have created a list view derived class and have passed it in to a Document Template and it displays as a plain white window. I was wondering how do i actually get the list ctrl to appear inside it.

What i want to do is just have a standard list control ie CListctrl displayed inside this CListView. But i can't get the list view to display how to i create the list view inside the window.

What code are you using at the moment?
"When a friend hurts us, we should write it down in the sand, where the winds of forgiveness get in charge of erasing it away, and when something great happens, we should engrave it in the stone of the memory of the heart, where no wind can erase it" Nish on life [methinks]

Just try using AppendMenu [Click Here for the MSDN explanation.]
Just use the MF_DISABLED flag to disable what you need.
Something like this:
pMenu->AppendMenu(MF_STRING | MF_DISABLED, 0, "Insert");

How can i declare the IDL interface, so a COM object can be assigned to a property of another COM object, and getting it back, just like the code below in VB.
-------------------------------------------------------------
Dim conn as MyLib.MyConnect
Dim msg as MyLib.MyMessage
Dim sentMsg as MyLib.MyMessage
set conn = new MyLib.MyConnect
set msg = new MyLib.MyMessage
msg.MsgData = "Hello, how are you "
set conn.Message = msg
MyConnect.SendMessage()
set sentMsg = conn.Message
--------------------------------------------------------------
Thanks

Do as the following:
[propputref, helpstring("property Message")] HRESULT Message([in] IUnknown* newVal);
[propgetref, helpstring("property Message")] HRESULT Message([out,retval] IUnknown** newVal);
Goodluck,
Dudi

normally, c++ calling is syncronized, here is an example:
//caller
int i;
GetInt(i);
//function
void GetInt(int&i)
{
............
i=5;
//point a
more code here
}//point b, end function
my question is, the caller gets value i=5 at point a or point b?
this question sounds silly and no interesting, but from first day of using COM to now, i don't undestand why following code works fine (thousands of times with no any trouble), see code bellow:
//COM code
void GetBSTR(BSTR*ppw)
{
BSTR str=::SysAllocString("my string in word");
*ppw=str;
//point a
::SysFreeString(str);
}//point b
the 'str' has been freed at point b, why caller has no trouble?
i know many people don't use ::SysFreeString, but anyway we should, otherwise who frees 'str'?
thx

It is just pure 'luck' that it works.
(The mem is marked free but the string is still there)

No, you should not free the string. When you return data through an [out] parameter, the data belongs to the caller. Freeing it like that destroys the data before the caller gets it.

Imagine this scenario:
Mate, can I borrow your shack by the beach for the weekend?
Um, Sure. I moved out a while ago tho, and left it abandoned, so I don't know what state it's in.
Now when you go to visit, you've got 3 chances:
1) It's still there, intact (but it may fall down later)
2) It's there, but it's gone damp and is now inhabited by nasty insects and scary hobos
3) It's already been condemmed and demolished
Due to timing, you're getting to your string before the memory manager has touched it, but its memory will be marked as no longer in use, so it could get reused by something else at any moment

Hi,
In my application, i have draw a 2D graph with a number scatter points. Now I want select two points by left-click the mouse two
times, and then change the positions of the points between the selected points (such as move points, linearization ...). Firstly, how to select the drawed points? how to give a mark of the selected point?
Thanks in advance?

Draw it with other color, other size - any way you want. See also MFC sample DRAWCLI - the great sample that shows graphic interface implementation. It uses PatBlt finction to mark selected objects. Remember also that standard way to select more than one object is using Ctrl key together with mouse.

i have 2 modeless dialog boxes (in same app), on each i display some pictures (16*16 pixels) - they are just pictures by DC (not windows).
i need to drag a pic from one dialog to another. i check mouse down on which pic then start drag. then use mouse move and mouse up (set capture) for drop.
i think it is possible to have better messages instead of simple mouse events even in this case.
do u have better idea?
thx

for some reasons, i need to create a CBitmap from buffer, the buffer is OK (BITMAPINFOHEADER+RGBQUADs+bitsBuf) because i display the buffer properly by StretchDibits function.
now i try to create CBitmap from it.
use CBitmap.CreateBitmapIndirect((BITMAP*)pBuf).
pBuf=BITMAP+bitsBuf. return value and size of the bitmap checked OK, but when select it into memory DC then BitBlt to client DC (all return values are OK), i see nothing.
do u know what is wrong?
and, why pBuf doesn't have color table?
Note: the CBitmat will be used in CToolBar (AddBitmap), so no DC should be involved.
thx.

I have a pdf file. I know there exists software
out there that lets me print on top of the pdf
file. Isn't there any way of printing user
text and a pdf file together so that text is
printed on top of that file?
I can convert the pdf to a bitmap and print text
with a bitmap easily. Unfortunately, the bitmap
does'nt print clearly. Isn't there a way to
print the pdf by a dos command and before that page goes to the printer, send some text with it so that it prints together?
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

I'm trying to have my EXE pass an WM_PAINT message to a dll with no luck. The last idea I had was to use the following
m_SpellCastingBar.SendMessage(WM_PAINT);
however this did not work as well. I have tried Invalidating the rectangle however I'm not sure if I'm even reaching the dll with this call as the WM_PAINT message is not getting retrieved by the dll.
Might there be something I am missing?
Thanks!

You should not pass WM_PAINT messages to windows. Windows will ignore them anyway. Windows only generates paint messages itself if the message queue for that thread is empty. Even then the target window needs to have an invalid area on it window rect for a paint message to be generated. When you were looking to invalidate the rect of the window that is more along the lines of what you need to do.
If you want to force a repaint of the window use the RedrawWindow function. Here is an example.
m_SpellCastingBar.RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_NOERASE | RDW_UPDATENOW);
The first two nulls indicate that you want the entire window to be updated. The flags say that you are invalidating the update region of your window because you can validate the window as well and prevent WM_PAINT messages from being called. RDW_NOERASE says do not generate a WM_ERASEBKGND message, and the RDW_UPDATENOW flag says expedite this request, and send the WM_PAINT message before the function call ends.
Coincidentally, these two function calls will do the equivalent of the RedrawWindow function above.
m_SpellCastingBar.InvalidateRect(NULL);
m_SpellCastingBar.UpdateWindow();

In a C++ class for a COM class, I have a method declared (which is a [out, retval] parameter):
<br />
STDMETHODIMP CSimCom::toString(BSTR *strdate)<br />
{<br />
...<br />
*strdate = cstr;
}<br />
