I have developped a add-in explorer bar for Internet Explorer. In the DllRegisterServer() function I have also entering the class-id of the toolbar to the registry key...
HKEY_LOCAL_MACHINE/Software/Microsoft/Internet Explorer/ Toolbar/{Toolbar Class ID}
But the toolbar is not visible in the Internet Explorer right after registration. After registering the dll, when I open a new instance of IE the toolbar doesn't appears by default. I have to explicitely check going to IE's View/Toolbar menu thereafter. But with many other third party toolbars like Yahoo, Google etc. the toolbar appears by default for the first time.
Can any one pls tell me where am I really missing out? Is there any other registry entry needed to make the toolbar default visible? I have already compared with Google toolbar registry entries with that of mine. They are almost same.Or do I have code any thing exclusive for that?
Thanx in advance for a positive reply from any friend in need around the globe.

I am currently attempting to localize a dialog for Japanese. This dialog inherits off of CAxDialogImpl. The seemingly simple way to localize this was to set the _Module.hinstResource to our language DLL. This seems to find the dialog and seems to load it. It does call _DialogSplitHelper::SplitDialogTemplate which finds all the controls and builds the template. However when it proceeds to call DialogBoxIndirectParam it returns a -1. Called GetLastError and of course it returns "Operation Completed Successfully".
Then I tried to modify the dialog to use our internal resources. I did that by overriding DoModal and creating a Modal Pump. This allows me to use our internal dialog creation tools that are designed to load from our Japanese language DLL and if that fails load from the embedded English resources. However the Japanese dialog fails to load, and then StartWindowProc asserts when trying to load the English dialog. This is because _Module.ExtractCreateWndData() returns a NULL. (NOTE: I do AddCreateWndData() in the DoModal call). Also if set the application to load English only, then this dialog still doesn't come up but does not assert in StartWindowProc.
Anybody seen this before and solved it? Anybody have any articles on localizing CAxDialogImpl()?
All help is helpful, and appreciated...
Thanks,
Brian

Can someone check their VC++ 7 compiler whether it accepts multiple entries into a map with duplicate keys?
Maps are NOT supposed to accept duplicate keys!! This is a feature reserved only for multimaps.
In VC++ 6, multiple entries into a map with duplicate keys, are accepted.
Thanks.

Could you give a testcase where this happens? The following test program gives the appropriate behavior in VC6:
#include <map>
#include <iostream>
using namespace std;
typedef map<int,int> items_t;
int main(int argc, char* argv[]) {
items_t items;
if (items.insert(items_t::value_type(1,2)).second) {
cout << "First insert OK!" << endl;
}
if (items.insert(items_t::value_type(1,3)).second) {
cout << "Second insert OK (bad!)" << endl;
}
cout << "Value for key 1: " << items[1];
return 0;
}

Thanks for replying.
In your sample, you are doing "items.insert(items_t::value_type(1,2)).second", which is the value of the second half of the "pair<const K, V>" format. Your sample, in essence, simply changes the value of that second half from 2, to 3.
I'm talking about the key itself,
items.insert(items_t::value_type(1).first, items_t::value_type(99).second); It doesn't matter what integer value is placed in "second" (i.e. as much as "int" can hold). "second" is not the key; "first" is.

items.insert(items_t::value_type(1,3)).second Take a closer look. map::insert(value_type) returns a pair which is not the map::value_type. Instead, the second element of the pair is a bool which indicates success or failure. In this case, I'm trying to insert a new element into the map with the same key as the first element (1). It fails, since the key 1 already exists in the map.
Are you referring to retrieving a reference to a map element, then modifying the key? The STL specifies that the key for an associative container should be immutable, but some implementions do not enforce this (it may be possible to change the key in such a way as to not break the strict weak ordering or multiplicity rules -- the STL itself cannot determine this).

std::map can't hold more than one equivalent key+data pair. However, if you insert an equivalent key+data pair, the old key+data pair is replaced with the new one.

I have a COM object I'm using in an ATL project. One of the exposed COM interfaces is called IWTOnLoad. According to the COM object's documentation, a class implements the IWTOnLoad by having a method in the class called .onLoadComplete. How would I go about implementing this IWTOnLoad COM interface in an ATL project?
The graveyards are filled with indispensible men.

I'm assuming you're not using attributed COM-stuff (VS.NET-specific). I don't know anything about attributed COM-programming and I really don't care to know anything about it, because I think that's a bastardization. (Goodie, I got to bitch/vent a little )
Add a , public IWTonLoad in the list of inheritances (sp?) for the implementing class.
Then add a COM_INTERFACE_ENTRY(IWTonLoad) in the BEGIN_COM_MAP map.
Then you may (optionally) add the interface to the array of "supported" interfaces in the ISupportsErrorInfo::InterfaceSupportsErrorInfo(REFIID riid) method. It depends on if you implement ISupportErrorInfo and if you use the ErrorInfo features in COM.
Then you add the method using the STDMETHOD macro as all the "other methods" are declared.
Optionally, you can also add a interface IWTonLoad in the corresponding coclass in your idl-file if you want to make the interface visible in the type library.
That should be pretty much it. You're new to ATL-programming, aren't you?

Hi. I am having some trouble with the Web Browser 2 control. I am able to display my html file within a window in my program, but can't print it. I am using ATL only.
The Nagivate() method has no errors but afterwards the ready state is always READYSTATE_LOADING, even some time after the browser control displays the html. When I try to print with the ExecWB function, I get error "0x80040100 Trying to revoke a drop target that has not been registered". I think there may be problem with the way the object is created?
Here is my code:
<br />
#include exdisp.h
#include exdispid.h
#include mshtmcid.h
<br />
CAxWindow wndIE;<br />
RECT rc = {0,200,800,700};<br />
HWND hIEWnd = wndIE.Create(hWnd, rc, _T(""), WS_CHILD | WS_VISIBLE | WS_THICKFRAME);<br />
CComPtr<IUnknown> punkCtrl;<br />
CComQIPtr<IWebBrowser2> pBrowserApp;<br />
<br />
wndIE.CreateControlEx ( L"{8856F961-340A-11D0-A96B-00C04FD705A2}", NULL, NULL, &punkCtrl );<br />
pBrowserApp = punkCtrl;<br />
<br />
if (pBrowserApp)<br />
{<br />
CComVariant vEmpty;<br />
hr = pBrowserApp->Navigate ( CComBSTR("c:\\report.html"), &vEmpty, &vEmpty, &vEmpty, &vEmpty );<br />
READYSTATE ReadyState;<br />
hr = pBrowserApp->get_ReadyState(&ReadyState);<br />
Sleep(3000);<br />
hr = pBrowserApp->get_ReadyState(&ReadyState);<br />
<br />
hr = pBrowserApp->ExecWB((OLECMDID)IDM_PRINT, (OLECMDEXECOPT)PRINT_DONTBOTHERUSER, NULL, NULL);<br />
}<br />
Any advice or comments would be greatly appreciated.
Thanks, Joanne

Update Internet Explorer up to last version. Can will help

I've answered my own question now, but FYI, the constant IDM_PRINT should be OLECMDID_PRINT, ie
ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, &vArg, NULL);

Hi,
I have a vector of classes.
I would like to write the entire vector to disk
I would like then load the entire vector back into memory.
And idea of the best way to do this?

Looks like a good idea to me. I'll give that a try. Thanks for the link.

One solution is STL std::copy().

Hi there,
please tell in detail ,what do u really mean by resource in ur project.
Although if u want to create an ACtiveX control at run time.
u can do it if u have the class id of the component selected by user.
Class CWnd * wnd =new CWnd();
and using wnd->CreateControl method and passing the Class ID of the selected ActiveX control u can create the control , and this control can be created in design mode by setting creation flag as WS_DISABLED.
u can also get its IUnknown pointer, calling GetControlIUnknown of CWnd class ,
and thru this IUnknown pointer u can get IDispatch pointer and then u can enumerate all methods and
properties of this control and even can Invoke them at run time.
u can even open the property page of this ActiveX Control using OleCreatePropertyFrame API.
Regards

Hi All,
If it doesn't support serialization,Is there any way for saving data or whatever it may be.Could you please advise me?
Thanks in Advance,Deepa.
|
|

|

It doesn't, but there's no reason why it couldn't, although you'd need a base mechanism for fabricating objects prior to calling their serialisation method, similar to the MFC approach, unless anyone knows of a better way.
