You need to add a reference to a type library for your server in the file global.asa.
Like this:
<!-- METADATA TYPE="TypeLib" FILE="d:\path\to\typelib\or\server.dll" -->
I think that should help you.

I am not all that familiar with the STL so bear with me.
I need something that can hold a lot of information and
be resized fairly easily - I have thought of std::vector
for this purpose.
However, the data I am using is not int, double, long, etc...
Instead, it is a class, say for simplicity CString.
Is it possible to define:
<br />
vector<CString> StringStack;<br />
This compiles and I can seem to add "strings" to it
If so, how does one go about declaring and using an iterator for this?
Have tried:
<br />
vector<CString>::iterator itr;<br />
for (itr = StringStack.begin(); itr != StringStack.end(); ++itr)<br />
{<br />
cout << *itr;<br />
}<br />
But this doesn't seem to work. Is what I am attempting even possible?
Thanks.

Ok, I am guessing here. Does CString support iostreams? You might try using std::string.

I'm going to patent thought. I have yet to see any prior art.

I think I've got it.
I do need to overload << though.
|
|
|
|
|
Try this:
<br />
vector<CString> StringStack;<br />
<br />
StringStack.push_back(CString("John"));<br />
StringStack.push_back(CString("Kim"));<br />
StringStack.push_back(CString("Kathy"));<br />
<br />
vector<CString>::iterator itr;<br />
for (itr = StringStack.begin(); itr != StringStack.end(); ++itr)<br />
{<br />
cout << (LPCTSTR)*itr << endl;<br />
}<br />

Thanks for the reply. I think I've figured it out.
I actually wasn't using CString, but rather a user-defined
class. Nonetheless, I seem to have figured it out.
The following apprears to work:
<br />
using std::vector;<br />
using std::endl;<br />
using std::sort;<br />
using std::partition;<br />
using std::less;<br />
using std::bind2nd;<br />
using std::ostream_iterator;<br />
using std::copy;<br />
using std::back_inserter;<br />
using std::vector<CSpring>;<br />
<br />
void CSpringSolver::DumpSprings()<br />
{<br />
vector<CSpring>::iterator itr;<br />
for (itr = SpringStack.begin(); itr != SpringStack.end(); ++itr)<br />
{<br />
itr->ShowSpring();
}<br />
}<br />
I just need to overload << (if possible)

So I've authored the activeX control using ATL and used the wizard to implement the connection point I added. Of course the wizard generated that header file, '<NameOfProject>CP.h', and in that header was the class: 'CProxy<INameOfDispInterface>Events'.
Now here's my dilema...
I want the event handler, that is a member function of the MFC dialog containing the control, to close and destroy the dialog. Unfortunately when that happens, the COleControlSite with the ATL control in it also get's destroyed, and then when the 'Fire_<Event1>' method returns from the call to 'pDispatch->Invoke' it tries to call release on the CComPtr it held pointing to the COleControlSite (which was just destroyed).........hence a memory access exception.
I'd love for someone to point out what I'm doing wrong, or perhaps another way to do this.
Ultimately all I care about is having an MFC dialog that can destroy itself based on some kind of event from a contained ATL control.
thanks,
nebbish

I've created a toolbar for IE using ATL, and weird problem has showed up.
Everything is fine when I open up Internet Explorer and select View->Toolbars->mytoolbar, however, when i close IE after that and open it up again, there is only the first button visible on my toolbar.
When i hide my toolbar, restart IE and make toolbar visible (View->Toolbars->mytoolbar)everything is ok again (all the buttons do appear...), so the problem might be related somehow to IE initializing toolbars at startup...
Any comments?

Hi,
I have written a dll using ATL. In which I want to fire events from a call back function. When I tried to do that my program crashes.
So that I have implemented a hidden window (which I saw in an article in this site) and posting the message to that window. From there I fire the events. It is working quite fine.
But my problem is, when I closes the application which used my COM object, it crashes at the end. I cannot trace what is the problem.
I describe here step by step what I have written in my program..
1. This is the hidden window i have created..
// mywnd.h : header file
//
/////////////////////////////////////////////////////////////////////////////
// CMyWindow window
class CClsRecord;
class CMyWindow : public CWnd
{
// Construction
public:
LRESULT OnFireEventForThread(WPARAM wParam, LPARAM lParam);
CClsRecord *m_pControl;
HWND Create();
CMyWindow(CClsRecord *pCtrl);
// Attributes
public:
// Operations
public:
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CMyWindow)
protected:
virtual void PostNcDestroy();
//}}AFX_VIRTUAL
// Implementation
public:
virtual ~CMyWindow();
// Generated message map functions
protected:
//{{AFX_MSG(CMyWindow)
// NOTE - the ClassWizard will add and remove member functions here.
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};
/////////////////////////////////////////////////////////////////////////////
HWND CMyWindow::Create()
{
//Register a window class
LPCTSTR classname = 0;
classname = AfxRegisterWndClass(0);
//Create the window and return it's handle
CWnd::CreateEx(NULL,classname,NULL,NULL,1,1,1,1,NULL,NULL);
ASSERT(m_hWnd!=NULL);
return m_hWnd;
}
LRESULT CMyWindow::OnFireEventForThread(WPARAM wParam, LPARAM lParam)
{
CComBSTR bstr;
//This is a one-message-does-everything handler. If wParam is not
//set, that means our message has been sent to fire the even.
//If wParam is set that means we're being asked to destroy ourselves
if(!wParam)
{
if (lParam!=NULL)
{
bstr = m_pControl->GetEventMessage();
m_pControl->Fire_OnEvent(lParam,bstr.Copy());
}
}
else if(wParam==1)
DestroyWindow();
return TRUE;
}
void CMyWindow::PostNcDestroy()
{
//clean up this object
delete this;
}
2. In the ClsRecord class, I have created a thread like this
CMyWindow *pWnd = new CMyWindow(this);
HWND hwndTarget = pWnd->Create();
//create a thread for handling all the events
HANDLE threadHandle = CreateThread(NULL,NULL,
(LPTHREAD_START_ROUTINE)GetNextEventLoopInThread,
(LPVOID)hwndTarget,
NULL,
&Tid);
3. Now, I am sending the message to the window like this..
PostMessage(hWnd,WM_THREADFIREEVENT,(WPARAM)NULL,(LPARAM)CLS_END_CALL_EVENT);
4. Now I call the dll in a VB application. The events are getting fired without any problem. But when I close the vb application, my program crashes. If I use 'End' statement in VB also it crashes immediately.
I have absolutely no glue that what could be the probem? Is it because of a memory leak? Then how can I detect this?
Kindly help me..
Thanks in advance
with regards

Did you call CoInitializeEx(...) in both threads where you are accessing your object?
Don't forget to call also CoUninitialize() before the thread exits.

Hello,
My code looks like this:
struct CButton
{
COLORREF color;
BOOL select;
tagDRAWITEMSTRUCT pditag;
}MyCButton;
[helpstring("method DoOwnerButton")] HRESULT DoOwnerButton([in]DRAWITEMSTRUCT pstruct,int IID_BUTTON, TCHAR * Caption,int Wmessage,MyCButton pnew);
I am getting error:
error MIDL2025 : syntax error : expecting a type specification near "tagDRAWITEMSTRUCT"
Is that mean that I can not use Windows structure in idl file?
PLease answer as soon as you can
Tahnks in advance

Hello,
I want to use the latest collection classes from VC .NET so I chose hash_set. The collection is storing custom objects (not just plain ints) that have operator <. Can anyone show my how do define the hash_set and its corresponding hash_compare correctly?
Thanks

You only have to define operator < for your class:
class MyClass
{
public:
...
bool operator<(const MyClass& x)const
{
}
};

I wish it were that easy....
I get C2440 error (cannot convert from const MyClass to size_t). I think I must derive from hash_compare and implement custom hash method as the compiler does not know how to get a hash code for my objects...
Best regards,
Alexandru Savescu

This sounds strange. Could you post the code to see how you're using hash_set? I think it should work once you defined operator <.

Here's the code:
#include <iostream>
#include <hash_set>
using namespace std;
class MyClass
{
public:
int x;
MyClass (int a) : x (a)
{
}
bool operator < (const MyClass& OB) const
{
return x < OB.x;
}
};
int main ()
{
hash_set <MyClass> MySet;
MySet.insert (MyClass (2));
}

I write a control for script, but I can't return more then one parameters:
[out] VARIANT param1,
[out] VARIANT param2,
[out,retval] VARIANT *pret
now only one parameter will return well, is that script can't accept method that have more output parameters?
|
|

First I have to say, I like WTL so far and have decided to create a control instead of using MFC, my only question is this...actually i think i know the answer, but i'm not sure how...
How do I include an WTL control (mycontrol.h) in an MFC project???
What steps are required...?
Thanks...

My project compiles and builds and runs fine for debugging but when I try to build the release version I get the following error. Anyone ever seen this before?
error C2065: '_AtlModule' : undeclared identifier
I should mention that I was able to build the release before without a problem, then one day this showed up. I'm not sure what is going on. TIA for any assistance.

Hi all,
I have an application written in C++ using win32, it creates a few windows, has a menu etc. Nothing fancy. But it's becomming a major pain to add new windows, fancy controls and whatnot so I thought about using WTL instead of the raw API's.
Is that feasible? The app works fine right now so I would like to create the new windows using WTL, the existing may be converted in the future.

Yep, it's pretty easy.- Remove your include of windows.h; instead, include atlbase.h, atlapp.h, then whatever other ATL/WTL headers you need.
- Right after the atlapp.h include, add
extern CAppModule _Module; - In one of your CPP files, declare the global
CAppModule _Module; - At the beginning of
WinMain(), call _Module.Init(NULL, hInstance); (where hInstance is the 1st param to WinMain()).
