A pdf file isn't an image file, so it doesn't contain pixel descriptions, instead it contains descriptions of where to lay stuff out. if you need a line of pixels, then you'll need to load the whole pdf file, render it to a bitmap, and get the line from there

Hi all,
I'm looking to make a list of common code bugs so I can toss the basic code into a c++ console app and compile so I can practice debugging.
Please let me know if this is a stupid idea.

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.

You need to superclass it.

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?
