Hi !
I have a class named CGroup in a standard couple of file .cpp and .h, and I'd like to use a STL vector of CGroup s in a structure.
So I typdef ed it in stdafx.h (as explained in a CP article about using STL ) like that : typedef vector<CGroup> tv_Group . The problem is, the compiler is unable to find the "size" of a CGroup class, since the typedef occurs before the class declaration, and therefore throws an error.
I've also tried
class CGroup;
typedef vector<CGroup> tv_Group; unsuccessfully.
I can remember having seen a post here in the forum recently about exactly the same problem, but I have forgotten the proposed solution (Only to say, there _is_ a way to do it).
Thanks for any help.

what compiler error exactly do you get?
group.h must be included before typedef. forward declaration "class CGroup;" is not enough because compiler can't deduce the size of CGroup from it. it works if you have a vector of pointers to CGroup:
class CGroup;
typedef vector<CGroup*> tv_Group;
also, i would put the typedef in group.h instead of stdafx.h
hope this helps

Hi,
What could be the possible causes for a dragand drop operation to fail. I've used a COleDataSource Object and Initiated a drag operation with the COleDataSource's DoDragDrop method. I find that it has been returning from the ::DoDragDrop( Win32 API) instead of going into a loop. any help would be greatly appreciated. thanks in advance
Vijay.

I don't know if you have some money to pay for a SDK, but I know that Golden Hawk Tech. offers a C++ SDK to write very much formats. But as I mentioned it's quite expensive .
See http://www.goldenhawk.com/cpp.htm for details.

Nero also has an SDK. I think it's free.

Not quite. It needs Nero installed to run so it's not really "free"....

What is the fastest (in terms of performance) way to append text to a CEditview?

Hi, can someone help me understand what is being done here ? This is a code snippet from a Visual Studio Add-in project, and i have a few questions about it (after the sample).
HRESULT CCommands::Function(IDispatch* theDocument)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CComQIPtr<ITextDocument,&IID_ITextDocument> pActiveDoc(theDocument);
if(pActiveDoc == NULL)
return S_OK;
CComPtr<IDispatch> pDispTextSel;
pActiveDoc->get_Selection(&pDispTextSel);
if (pDispTextSel == NULL)
return S_OK;
Maybe i am in the wrong forum, and this is all trivial ATL/COM stuff that i lack . Sorry if the questions are dumb .
1.What is pActiveDoc ? A pointer on the Idispatch *theDocument ?.
2.Where can I find the description of the get_Selection method ?
3.Where can I find the descrition of the method available for pActiveDoc ?
4. What is AFX_MANAGE_STATE(AfxGetStaticModuleState()); being done for ?
Actually, what I'm trying to do is get the filename of the active file in the Visual C++ editor...I was looking at another Add-In src to try and understand how this functions, but this is all not as easy as I thought

1. pActiveDoc is a smart pointer to theDocument (wraps the pointer and takes care of object reference counting). since there is the Selection property, i guess that it is really a TextDocument object of DevStudio.
2.
Selection Property
Applies to: TextDocument object, TextWindow object
Gets the TextSelection object, which represents the selected text.
Syntax
object.Selection
Parameters
object - An expression that evaluates to a TextDocument object or a TextWindow object.
Remarks
The Selection property has the TextSelection type.
For the TextDocument object, the Selection property gets the object representing the text selected in a document's active view or in the topmost view if no views are active.
For the TextWindow object, the Selection property gets the object representing the text selected in the text window.
3. check the MSDN: Visual Tools and Languages -> Visual Studio 6.0 Documentation -> Visual C++ Documentation -> Using Visual C++ -> Visual C++ User's Guide -> Automating Tasks in Visual Studio. there's the description of VisualStudio object model.
4. AFX_MANAGE_STATE must be called at the beginning of every exported method in MFC dlls to correctly set the module state. find more details in MSDN
5. call Name or FullName property on pActiveDoc object

hello,
How can i modify style of child window,
i use
pChild->ModifyStyle(0,WS_THICKFRAME,SWP_NOMOVE | SWP_NOSIZE );
but the window haven't resizable border.
you know how to do this ?
thx in advance
|
|
|
|
|
does the window have WS_DLGFRAME style also? if it does, i think you will have to remove it. some window styles cannot be used together. also, for some styles you have to call SetWindowPos() after ModifyStyle(), to make them active (IIRC, ES_READONLY for edit controls ,etc)
|

thx Zed
my window doesn't have WS_DLGFRAME . I have a little problem with
SetWindowPos() :
pChild->SetWindowPos(NULL, 0, 0, 0, 0, SWP_FRAMECHANGED |<br />
SWP_NOMOVE | SWP_NOSIZE |<br />
SWP_NOZORDER);
after SetWindowPos my window has resizable borders, but i put the flags SWP_NOMOVE but my view move and it does not remain where it was.
So i would like to get border without call SetWindowPos it isn't posible ?

i'm not sure
the problem is that SWP_FRAMECHANGED flags resulst in WM_NCCALCSIZE being sent to window, which forces the window to change its size. maybe you can add SWP_NOREDRAW flag which will defer repainting, and then call MoveWindow() to resize the window to its previous size. i'm not sure if this will work, but you can try

before call ModifyStyle ,i moved the view with ScrollWindow, there is a possibility to get "window scrolling" position (and not use GetScrollPos for scrollbar) ?
thx again Zed

|

GetScrollInfo(), but i'm not quiter sure what are you trying to achieve. can you post some more details?
|
|
|
|

in fact i scroll the view without use the scrollbar.
when i click in the view and move my mouse i do :
if (pMsg->message == WM_MOUSEMOVE) )
{
if (pMsg->wParam & VK_LBUTTON)
{
POINT Point = pMsg->pt;
long ScrollX = Point.x - m_Point.x;
long ScrollY = Point.y - m_Point.y;
ScrollWindow(-ScrollX,-ScrollY);
m_pPoint = Point
}
}
so i move my view and i don't know really its coordinates.
when i use :
pChild->SetWindowPos(NULL, 0, 0, 0, 0,SWP_FRAMECHANGED |
SWP_NOMOVE | SWP_NOSIZE |
SWP_NOZORDER);
my view loose its scrolling, so i want to know its coordinate before SetWindowPos .
Or get a way to put the sizable border without use SetWindowPos .
have you any idea ?

i'm not sure if i correctly understood the relationship between the view and pChild. is that the same window or are they parent-child?
if the view is scrolled only from your code, maybe you can accumulate ScrollX and ScrollY in every WM_MOUSEMOVE handler call and thus have the total ammount by which the view was scrolled, so you can use that (i'm just guessing here).

pChild is the parent child.

OK thx, i'll go to do this, i hoped there was a "function" like GetScrollWindow"....but no.
thx Zed for you help!
