Ok, another relatively simple question that I just can't get my head around...
I am working on an HTML Editing program, that needs to get the source code for a document from the MSHTML Editor. I am using the following function to return the document object, and then what I thought would be the source code, in a CString. The problem is that the string always contains the text "[Object]" rather than the source code. What am I doing wrong? or what do I need to do to get the source as a string?
CString CMyView::GetText()
{
BSTR bStr = 0;
HRESULT hr = E_FAIL;
IHTMLDocument2* pDoc = NULL;
if (SUCCEEDED(HrGetDoc(&pDoc)))
{
IHTMLElementCollection* pElementCol = NULL;
hr = pDoc->get_all(&pElementCol);
if (SUCCEEDED(hr))
{
pElementCol->toString(&bStr);
pElementCol->Release();
}
pDoc->Release();
}
....
}
The function 'HrGetDoc(IHTMLDocument2 **ppDoc)' simply returns a pointer to the IHTMLDocument2 object. I know this is valid because I can use it elsewhere to update the document.
According to the MSDN documentation, 'IHTMLElementCollection::toString(**BSTR)' will return a string representation of the element collection - in this case the entire document. I also tried directly using 'IHTMLDocument2::toString(**BSTR)' but i still get the string "[object]" retuned.
What am I doing wrong. I suspect that I still need to do one more step before I can get the document, such as '[object].toString(...)' but how do I do this?
Again, any help you can give me will be appreciated.

Hi
Enumerate the Element collection
and then use IHTMLElement::get_outerHTML to retrieve the HTML of the individual elements

Thanks, I have something 'kind of' working now  . But I can only get the contents between the BODY tags. Even getting the content between the HTML tags would not be enough, as the user could have a comment before the start of the document (or not have HTML tags at all).
Any solutions?
Thanks again,
David Wulff

At a guess,
All the code should be between either the HEAD and BODY tags, or just the HTML tags So when you enumerate the Tags these are the only two you actually need to find.
If there are no HTML tags then it isn't HTML !
as HTML is a standard

I am trying to communicate with a RS-485 device through a serial port (COM1). Everything works okay via RS-232 or using a special converter which toggles the RTS line high while TX is active. I have tried using RTS_CONTROL_TOGGLE or EscapeCommFunction (SETRTS/CLRRTS) without success. I suspect that either the RTS line is not held high quick enough (thus character is not sent) or that the RTS line is held high too long (thus misses the echoed character).
Suggestions or experiences under this configuration?

Any one have any ideas on this problem that I sent off to msdn ?
http://msdn.microsoft.com/library/devprods/vs6/visualc/vclang/_iostream_a_streambuf_derivation_example.htm
C++ Visual Studio 6 with SP4 on Windows NT 4.0
There are contradictory examples of filebuf using the sync method and the fd accessor method(s). The C++ standard documents the methods and so does Microsoft, however MS's library doc's are full of examples of using features that they don't support and they do not show workarounds in fact the class filebuf is total unusable in buffered IO situations and has no way of working without manually changing your include files.
If this was a support question I could word it as ...
When using buffered IO with the filebuf class how does someone within the sync method pysically get the output to the disk as a buffer, usually this could be done by calling the base filebuf class sync but it does not implement buffering properly and only calls a flush function rather than checking for unbuffered == false then calling write then calling flush. Also I cannot compensate by getting the file descriptor and manually doing the write because the filebuf::fd is not supported!!!

Hello,
I'm currently trying to get a grip of the STL. All I could find so far is one (fairly poor) tutorial in the MSDN.
Does anybody know where to get some good tutorial for STL?
Thanks,
Matthias

Hi,
check this link:
http://www.sgi.com/Technology/STL/other_resources.html
The best solution is of course to buy a book with good examples.

i began loving STL after reading:
"Thinking in C++ 2nd edition"
by Bruce Eckel
i think two or three of the chapters are dedicated to STL... and are full of examples...
hope this helps

Dear Sam.
With the Help of ur WFC Lib. we tried to interact with Tape Drive for Getting Header Info., Catalogging, and BackupRead....
but we failed in the first phase itself...(Getting Header Info..)
The method OPEN in CMIRCOSOFTTAPE fails to read the info.
Could u help us to overcome this problem.???
Any ideas and Suggestions would be welcome...

"can anybody tell me how i can format source code in

Let's test. The following code is inside a < pre >...< /pre > block:
void CMyClass::OnSomeEvent()
{
}

I want to trigger a started NT service on some event. i.e a service should activate on that event and perform its funtionality.
The invoking event should be passed from another VC application.
Can anybody tell me how can I do it.
(I want something like as Message Passing within different applications)
Please guide.
Thanks in advance

You might try having a look at my DCOM programming tutorial, which shows you, step-by-step, how to do this with DCOM, where the server program (which has the events and the functionality) is a Windows NT Service.
The tutorial starts with Step 1, and then Back and Next links are provided to help you move through the steps.
Hope this helps

If you get the book "RPC for Windows NT" and read and understand it, then you can code your own special interface into the NT service as the RPC server and into your VC app as the RPC client. I do this a lot using the Local RPC and it works great.

Hi,
COM object is a binary file, and dll also binary file.
what is difference between them (internally)?
thanks

Think of things this way...
You know how, in a C++ program, you have all sorts of objects, like CWinApp, CMyView, CMainFrame, etc.?
These are all called "code-level" objects; that is, the only thing that knows about them is the program's source code.
COM takes objects to the next level, that is, the "binary level." Think again of a class, but this time another executeable program instantiates it in memory and calls its methods and properties. Although this time, the object is not in your code, it's in the binary.
DLLs are simply libraries of functions that are like the .LIB files we use for linking things statically, only this time, the linking happens "dynamically", or during run time
Cheers,
Brian Hart

Hi,
COM object can be stored in the DLL or EXE file. When a COM object is stored in the DLL the only difference with the usual DLL file, is that the COM DLL must have several COM related methods:
DllGetClassObject
DllRegisterServer
DllUnregisterServer
DllCanUnloadNow
See description of these functions in MSDN for more details...

Hello Everybody,
I know this is COM/DCOM but since Visual C++ is used so much to do this, I thought I would post here too
I have written a comprehensive, seven-step tutorial which is easy enough for beginners to use, and posted it on The Code Project to help you get started on DCOM programming.
It's as yet an "unedited reader contribution" but I want to invite you to look at it anyway and let me know what you think. Feedback is so very needed on this kind of a project.
The tutorial starts with Step 1, and is at (for the moment) http://www.codeproject.com/useritems/HelloTutorial1.asp
Cheers,
Brian

Ok, I have two classes, eg, CView1 and CView2. I want to call a function in one view to get some text, then call a function in the second view to set the text to what I just got. Following so far? I need to do this in a function in my CWinApp derived class.
The program is set up to be MDI, and both views are attached to the same CMDIChildWnd frame, switched between with tabs. I am need to do this so I can update one document based on the other when the views are switched.
For example, when the tab is clicked to switch the view to view1 from view2, I call "theApp.SetVew1_from_View2()", which needs to be like:
void CMyApp::SetVew1_from_View2()
{
CString strView2 = CView2::GetText();
CView1::SetText(strView2);
}
Except that I obviously need to get valid pointers to each view. This is my question (finally ), how do I get pointers to each view (attached to the same child frame)?
I have tried getting the CMDIFrameWnd, then the active child frame, but I can't get pointers to each view from here.
Any light you could shed on this would be greatly appreciated.
Thanks in advance,
David Wulff

An approach is, instead of the app getting pointers to the views, how about the views giving the app pointers back to themselves?
Add two public member variables to CMyApp, and #include lines, like this:
#include "View1.h"
#include "View2.h"
class CMyApp : public CWinApp
{
...
public:
CView1* m_pView1;
CView2* m_pView2;
}
// IN MYAPP.CPP
CMyApp::CMyApp()
{
// Initialize view pointers to NULL
m_pView1 = NULL;
m_pView2 = NULL;
}
void CMyApp::SetView1FromView2()
{
if (m_pView1 == NULL || m_pView2 == NULL)
return;
m_pView1->SetText(m_pView2->GetText());
}
// NOW IN View1.cpp
CView1::~CView1()
{
theApp.m_pView1 = NULL;
}
void CView1::OnInitialUpdate()
{
CView::OnInitialUpdate();
...
theApp.m_pView1 = this;
}
// AND IN View2.cpp
CView2::~CView2()
{
theApp.m_pView2 = NULL;
}
...
void CView2::OnInitialUpdate()
{
CView::OnInitialUpdate();
...
theApp.m_pView2 = this;
}
And voila!
Cheers,
Brian

Thanks. I'll play around with this idea, but just one question:
If I have more than child frame open, wont the pointer 'point' to the most recently created one.
Actually forget this, I have just thought of adding the 'theApp.m_pViewX = this;' each time the child frame is selected. After all, only one can be shown at a time.
Thanks again,
David
