Disable "Minimize CRT use in ATL" in your project properties, and it should work.

Thanks a lot! That's really fantastic.

Does any one know how to make modeless dlgs/propertysheets destroy by themself?
my code:
<br />
pdlg = new CMyDlg;<br />
if(pdlg && pdlg->Create(hwndParent))<br />
pdlg->ShowWindow(SW_SHOW);<br />
<br />
void OnClose(UINT uCode, int nID, HWND hwndCtrl)
{<br />
DestroyWindow();<br />
}<br />
void OnNcDestory(void)<br />
{<br />
m_hWnd = NULL;<br />
delete this;
}<br />
But it works fine in MFC
http://www.codeproject.com/dialog/gettingmodeless.asp[^]
any idea?

Override OnFinalMessage.
void OnFinalMessage(HWND /*hWnd*/)
{
delete this;
}

Crashed!
I found that the m_hWnd is NULL when running to "delete this;".
But m_hWnd is reset again after the destructor of base class "CWindowImplRoot" is invoked-- line 2752 in file atlwin.h
BTW: I'm using WTL8.0.

Are you using VC6? or VC7+? If VC6 maybe you should look at Michael Dunn's post.
If it's happening in VC7.1, there was this long discussion on the WTL Yahoo forums a while back. I'm not sure if VC8 suffers from this problem.

The windowing code is from atlwin.h which is from ATL. So this is not part of WTL. WTL is built on top of ATL's windowing code so having the most updated WTL doesn't help.
New versions of ATL only ship with new versions of Visual Studio. The ATL files that is in the Platform SDK seems rather old.

There is a CBitmapButton IDC_CLOSE in my Dialog.
I destroy the whole Dialog in OnClose callback function
<br />
void CDlg::OnClose(UINT uCode, int nID, HWND hwndCtrl)<br />
{<br />
DestroyWindow();<br />
}<br />
When the Main Dlg is deleted, it crashed at line 2752 in file atlwin.h
<br />
if(m_hWnd != NULL)
{<br />
ATLTRACE(atlTraceWindowing, 0, _T("ERROR - Object deleted before window was destroyed\n"));<br />
ATLASSERT(FALSE);<br />
}<br />
The m_hWnd is the handle of button IDC_CLOSE!

hi
how to create an ATL class which is derived from IDIspEventImpl interface???
"Every morning I go through Forbes list of 40 richest people in the world. If my name is not in there, I go to work..!!!"

1. Add IDispEventImpl as a base class
class CAboutDlg: public CAxDialogImpl<CAboutDlg>,
public IDispEventImpl<IDC_ABOUT, CAboutDlg, &DIID_DWebBrowserEvents2, &LIBID_SHDocVw, 1, 1>
2. Add a sink map to the class
BEGIN_SINK_MAP(CAboutDlg)
SINK_ENTRY_EX(IDC_ABOUT, DIID_DWebBrowserEvents2, DISPID_DOCUMENTCOMPLETE, OnDocumentComplete)
END_SINK_MAP()
3. Implement the event handler - this is the implementation, you obviously need a corresponding declaration in the class.
void __stdcall CAboutDlg::OnDocumentComplete(IDispatch* pDisp, VARIANT * URL)
{
Do Stuff Here
}
This is from actual working code - a dialog that embeds HTML display using IE.
HTH!

Has anyone tried compiling a VC6 MFC application using the VC7.1 compiler?
I followed this simple article on making VC6 to use the VC7.1 compiler.
http://pixwiki.bafsoft.com/wiki/index.php/Using_the_Optimizing_VC7_Compiler_with_the_VC6_IDE
Then all the errors I've been getting have been from the actual C:\Program
Files\Microsoft Visual Studio\VC98\MFC\Include\ folder (loads of template
syntax errors).
Surely Microsoft must've made a portability/conversion for VC6 MFC to be
used under VC7.1?
|

Doesn't surprise me - templates is the area where VC7.1 scores highest over VC6, in that it's nearly completely compliant with the C++ Standard, rather than being a not great attempt to be compliant with a draft standard (which was all that was around when VC6 was developed).
Let me guess - have you had to add/remove lots of 'typename' keywords? That's probably the biggest difference - VC6 will assume that dependent names are types, which isn't standard compliant. So, in this example from afxtempl.h (I compiled it with VC8)
<code>template<class TYPE, class ARG_TYPE>
CList<TYPE, ARG_TYPE>::CNode*
CList<TYPE, ARG_TYPE>::NewNode(CList::CNode* pPrev, CList::CNode* pNext)
{
... some more code ...
</code>
VC6 will assume CList<TYPE, ARG_TYPE>::CNode is a type, but VC7.1+ won't...because it might not be. You need to put typename CList<TYPE, ARG_TYPE>::CNode to tell the compiler that you are making a guarantee that it's a type.
Anyway - I'd suggest that you're out of luck - you should be OK compiling console and simple Win32 programs, but MFC and ATL programs require a match between compiler and library. That's the portability between VC6 and VC7.1 - you recompile you MFC programs with thea correct compiler/library match.

Hi All,
Can anyone tell me if there is an easy way to add 2 vectors?
Thanks and Regards,
Anil
|
|
|
|
|
std::vector<myType> v1;
std::vector<myType> v2;
for (std::vector<myType>::iterator
iter = v2.begin();
iter != v2.end();
iter++) {
v1.push_back(*iter);
}
|
|
|
|
|
|
Or without an explicit loop:
std::vector<myType> v1;
std::vector<myType> v2;
std::copy(v2.begin(), v2.end(), std::back_inserter(v1));
This code assumes:
#include <vector>
#include <algorithm>
#include <iterator>

If you mean make a third vector by summing two other vectors? If yes this code will do it:
vector<int> v1, v2, vout;
ASSERT(v2.size()>=v1.size());
transform(v1.begin(), v1.end(), v2.begin(), back_inserter(vout), plus());
This code assums the following:
#include <vector>
#include <algorithm>
#include <iterator>
#include <functional>
using namespace std;

Are the pixels in the RGBQUAD array stored from top left to bottom right of the image. I am trying to test sections of an image for color and I need to know how the pixels are stored.
For example:
bi->bmiColors[0].rgbBlue is the top left pixel and bi->bmiColors[lastindexvalue].rgbBlue is the bottom right pixel
Is that correct?
|
|
|
|
|
Yes that is where those pixels would be stored, provided the array was loaded properly. But working with images is usualy more complicated than that, it depends on the format of the image and who is filling the array.
INTP
Every thing is relative...

i have an activex control.
when i place it on a webpage like this
<OBJECT id="myObj" codebase="myObj.CAB#version=1,0,5,0" classid="clsid:57F..." border="0" height="514" width="655">
and in Javascript i write a func
myObj.OnSave();
it works perfectly, OnSave function is called successfully
but if i embed the same control on either VB or VC the OnSave function is not in the exported list at all
Not even in the object browser 
so i tried
CString szStr("OnSave");
IDispatch *pObj;
pUnk->QueryInterface(IID_IDispatch,(void**)&pObj);
DISPID FuncID;
OLECHAR FAR* szMember = szStr.AllocSysString();
HRESULT hr = pObj->GetIDsOfNames(IID_NULL,&szMember,1,LOCALE_SYSTEM_DEFAULT,&FuncID);
::SysFreeString(szMember);
this also return DISP_E_UNKNOWNNAME
i am stumped the control is same then why this kind of stuff
can anyone shed more light on this
The control is not written by me and i cannot contact the guy who did wrote it
please help
