I'm not sure whether you will get precise timing of 1 ms because as per the windows concept, each process will get 20ms of time for it's execution, it's depends on the scheuduler that your process will get scheduled.So a in the user mode, we could not ensure the correctness of the timer.

We can use waitable timer for the same, since it is a kernel object, it will signal at the specified time. But I doubt whether your application can handle do the required processing thsi small amount of time. Anyway check this.

The Windows multimedia timers are supposed to offer the programmer the ability to get timer resolutions better than what is typically available (around 10ms on Windows XP).

I have not tested these functionalities extensivelly, but I did notice a subjective improvement in a 3D animation I was building.

Check timeBeginPeriod function and the related multimedia timer functions. The minimum resolution that can be set is 1ms.

no need of doing all this.

just right click on the dialog. Take properties from the menu.

In the general tab u can find a combobox called menu. Select "IDR_MENU2" from that one. Build and run the project. Cool | :cool:

There is nothing wrong in your code.
It is working fine here.

Just debug the code once,keeping a breakpoint at OnCreate()

Can u give some more details ??

To know the routing of the command,Keep message boxes in each view and run the application.

I think this must help you to know the command routing.

IHtmlPopup Error [modified]

I am building a BHO that is meant to popup a IHtmlPopup window on a mouse over image event. All the code works fine if the image is in the main Window.

However if the image is in a frame then I get the following error:

{"Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"} System.Exception {System.UnauthorizedAccessException}

This happens when I try to create the Popup Window or access its Document
The code below is in C#, but I think it would apply to C++ too.

I have tried getting the parentWindow from the Frame's document and from teh main document.

<br />
//IHTMLWindow4 parentWindow = (IHTMLWindow4)FrameDocument.parentWindow;<br />
IHTMLWindow4 parentWindow = (IHTMLWindow4)PageDocument.parentWindow;<br />
<br />
//This line will work, but if you look at the Document Property, you will see the exception<br />
IHTMLPopup popUp = (IHTMLPopup)parentWindow.createPopup( ref argIn );<br />
//This line will throw the exception<br />
IHTMLDocument2 popupDoc = (IHTMLDocument2)popUp.document;<br />

Any ideas?

Thanks, but I am not sure that is my problem. My code works when there are no frames in the html. It fails when we have frames. Also, I can get it to work using simple javascript even in frames. Just cant get the C# code to work with frames.

Copying Data to the Clipboard
Having registered a Clipboard format, we can look at copying data to the Clipboard. Let's first look at the OnUpdate. . . handler for the Edit Copy command:

void CClipView::OnUpdateEditCopy(CCmdUI* pCmdUI)<br />
{<br />
    int i = m_wndList.GetSelCount();<br />
    pCmdUI->Enable(i > 0 ? TRUE : FALSE);<br />
}

If no items are selected, the command is disabled. This does two things: It shows the user the command won't do anything (it's grayed out), and it prevents us from getting Copy commands when there is nothing to copy. Let's look at the code for doing the actual copy operation:

void CClipView::OnEditCopy()<br />
{<br />
    // Get the number of selected items.<br />
    int iCount = m_wndList.GetSelCount();<br />
    ASSERT(iCount > 0);<br />
    // Get the list of selection IDs.<br />
    int* pItems = new int [iCount];<br />
    m_wndList.GetSelItems(iCount, pItems);<br />
    // Create a list.<br />
    CMyObList ObList;<br />
    // Add all the items to the list.<br />
    int i;<br />
    CMyObj* pObj;<br />
    for (i=0; i<iCount; i++) {<br />
        pObj = (CMyObj*) m_wndList.GetItemData(pItems[i]);<br />
        ObList.Append(pObj);<br />
    }<br />
    // Done with the item list.<br />
    delete pItems;<br />
    // Create a memory-file-based archive.<br />
    CSharedFile mf (GMEM_MOVEABLE|GMEM_DDESHARE|GMEM_ZEROINIT);<br />
    CArchive ar(&mf, CArchive::store);  <br />
    ObList.Serialize(ar);<br />
    ar.Close(); // Flush and close.<br />
    HGLOBAL hMem = mf.Detach();<br />
    if (!hMem) return;<br />
    // Nuke the list but not the objects.<br />
    ObList.RemoveAll();<br />
    // Send the Clipboard the data.<br />
    OpenClipboard();<br />
    EmptyClipboard();<br />
    SetClipboardData(theApp.m_uiMyListClipFormat, hMem);<br />
    CloseClipboard();<br />
}

The number of selected items is used to create a temporary array of selection IDs. The IDs are set into the array by calling GetSelItems. A new CMyObList is created and the pointer to each object is added to the list. Note that we are adding a reference to an object that is in use elsewhere, so it's important that we don't delete these objects by mistake when we're done here.

Once the new CMyObList object has been built, a CSharedFile is created and an archive is created on top of the shared file. We can now serialize the list to the archive and, hence, to the shared file in memory. Once that's done, the memory of the shared file is detached, ready for sending to the Clipboard. The temporary CMyList object has all its items removed, not destroyed. The list object itself is, of course, destroyed when the function exits. The Clipboard is opened, emptied, and set with the data from the shared file. The memory block now becomes the property of the Clipboard. Finally, the Clipboard is closed.

If you use the Clipboard viewer after copying a list to the Clipboard, you'll see an item from your private format. You can't view the data, of course, because the Clipboard has no way of understanding it. You can add that capability for owner-drawn Clipboard items if you want the user to be able to see the data in the Clipboard viewer.
