I don't know if this applies to 8.0, but it did to 7.x: If you want to use the ATL (& MFC)-implementation of CString, then make sure to include atlstr.h just after atlbase.h (at the very least before any of the wtl-includes). WTL has its own CString-implementation, which it'll enable if ATL::CString isn't present by the time of inclusion. This can create all kinds of bizarre type mismatches if you include atlstr.h after WTL.

I want to create a child(?) window on a form that overlaps the non-client area of the main window. Similar to the Office 2007 application button (see http://images.tomshardware.com/2006/03/10/office_2007_beta_2_02.jpg).
I have tried setting the window style to WS_POPUP, but the window is still clipped to the client area of the frame. The only way I can get around this is to use a screen DC, but that doesn's seem like the right thing to do (and I have to manually determine when the window shoudl be visible so I don't draw over other windows.
Any hints would be greatly appreciated.

i developed an ActiveX control with ATL,vs2005
When I try to open my ActiveX Control with Dependency Walker in client machine
i got the following error:
"Failed to load due to a mismatched machine type with one or more of the dependent modules"
It need "CoreDll.dll".
I saw below article on MSDN to troubleshoot the issue
http://msdn2.microsoft.com/en-us/library/aa459142.aspx
but it looks like it is all about Windows CE and .Net compact framework. I am using Windows XP SP2.
Any help is appreciated.

Instead of client m/c, use dependency walker on development m/c to detect all dependencies, and ship them along with activex.

use dependency walker on development m/c
"atl80.dll" and "msvcr80.dll" are needed ,i ship them along with the activex ,but it can not work.

Hi all,I want to use bho to catch the message of mouse right click.It seems there exists one way:
Using ATL.I followed MSDN:rewrite SetSite,and then assign FindConnectionPoint，then advise，at last catch events to invoke，the following is example codes in invoke():
switch (dispidMember)
{
case DISPID_HTMLELEMENTEVENTS_ONCLICK:
CComPtr< IDispatch > pDisp;
IHTMLDocument2*pHTMLDoc;
mWebBrowser2->get_Document(&pDisp);
if (pDisp!=NULL)
{
pDisp->QueryInterface(IID_IHTMLDocument2, (void**)&pHTMLDoc);
pHTMLDoc->elementFromPoint(myPoint.x,myPoint.y,&pElement);
}
...
}
But,how can I know myPoint,where can I get it?
|
|
|
|
|
pDispParams parameter of IDispatch::Invoke would have that infromation.
|
|
|
|
|
I have the same question.
Could you pls let me know how to get the point from DISPPARAMS* pDispParams

If you hide the for loop in InterIpqam::opertator=(),and then you rebuild and debug it, you maynot find the memory leak prompt in output box. Why?
I am very puzzled.

- When you post code, can you (please) use a setting where your
#include angle brackets don't get converted to tags - the "Ignore HTML tags in this message (good for code snippets)" checkbox should be checked - There will be no memory leaks in the code you've posted - it doesn't actually use any of your
structs - I added some code to instantiate some
interipqam items and assign them - there were no memory leaks that I could see.
I think you can be reasonably confident that std::vector works as advertised, at least as far as allocating memory goes.

Firstly, thanks for your answer.
Secondly, let me go on with my question.
Of course, I know it not creat any objects, so it doesn't have any memory leak.
But in vc's output when you debug it, you may find memory leak prompt info.
I copy the prompt info here.
Detected memory leaks!
Dumping objects ->
{42} normal block at 0x00441F70, 33 bytes long.
Data: < C > 00 43 00 CD CD CD CD CD CD CD CD CD CD CD CD CD
{41} normal block at 0x00441FC0, 40 bytes long.
Data: < |L > 14 7C 4C 10 16 00 00 00 00 00 00 00 00 00 00 00
Object dump complete.
So I wonder why?Can u tell me the cause? Thanks

I didn't have any memory leak information when I ran your code. However, to find the source of those leaks, you could try using _CrtSetBreakAlloc to get the runtime to break when the relevant memory allocation is performed. Looking at your text, you need to look for allocations 41 and 42 (the numbers inside the curly brackets).
However, I think you'll find those allocations are made by the C runtime library *before* your code is ever called (I compiled a console application with the line int* a = new int; and that was allocation number 88), so they aren't allocations you need to worry about, because the runtime library clears them *after* your code exits.

my code:
<code>CComQIPtr<IHTMLDOMNode>pRootNode(lpParentDisp);
CComPtr<IDispatch> spChildren;
if(FAILED(pRootNode->get_childNodes(&spChildren)))return;
CComQIPtr<IHTMLDOMChildrenCollection> pChildColl(spChildren);
long lCount = 0;
pChildColl->get_length(&lCount);
for (long l = 0;l<lCount;l++)
{
CComPtr<IDispatch> spChild;
pChildColl->item(l,&spChild);
CComQIPtr<IHTMLDOMNode> pChild(spChild);
CComQIPtr<IHTMLElement> pElement(pChild); // I don't obtain the point
}</code>
please somebody help me ! thanks........

Hi,
I've created a com object in ATL ( still learning ). However, somethimes you get to see such nice online installers.
Someone goes to a specific page, gets the error that he needs some files installed on his computer. then in iexplore, a nice goldbar kicks in wich automaticly sends you the nessesary files on accept. even better, they totally install and register themselfs. So how can i create this? i'm using apache 2.* on a debian linux server ( sorry, trying to jump to winserv 2003 any time now )

1 .write a inf file like this sample:
; Sample INF file for AVJumbee.dll
[version]
; version signature (same for both NT and Win95) do not remove
signature="$Chicago$"
AdvancedINF=2.0
[Add.Code]
AsiaViewFTPCtrl.dll=AsiaViewFTPCtrl.dll /// com dll
; needed DLL
[AsiaViewFTPCtrl.dll]
file-win32-x86=thiscab
clsid={42FD5C77-532D-4BB0-A284-F0D8FB124049} // com guid
FileVersion=1,00,0,3
RegisterServer=yes
; end of INF file
2 download CabArc.Exe file
3 run cmd:CABARC -s 6144 n AsiaViewFTPCtrl.CAB AsiaViewFTPCtrl.dll AsiaViewFTPCtrl.INF //make a .CAB file
4 codesign2005 tools
5 put the sign cab file to web

I used CWindow::Create() to build a new POPUP window in VC++6.0/WTL. I wanted to
make the window behave like a dialog without using a dialog resource template. By behave like a dialog, I mean the running process suspends until the dialog window returns/closed.
Can you please help me with that? Thanks.

Gurus,
If I have an STL list (doesn't matter what of) and I sort it, how can I add one element to the list, whilst maintaining the sort order?
All I can think of to achieve this is to either: (1) add the new element to one end, and run sort() again, or (2) iterate through the entire list, checking the sort predicate against each element. Neither of these seem particulalrly appealing.
Does anyone know the most processor efficient way of doing this please ?
thanks,
Neil.
cheers,
Neil

They hide that information in the documentation[^]
Lower_bound is a version of binary search: it attempts to find the element value in an ordered range [first, last) [1]. Specifically, it returns the first position where value could be inserted without violating the ordering.
However that might not be the "most efficient" for your application. There are several things to consider. If you use STL much you should have Scott Meyers book as it discusses efficiency issues.

It probably won't be - I don't think the structure of std::list iterators is terribly conducive to binary searches - could be wrong, mind.

std::deque would probably be a better choice in most cases.
