Hi,
I have an MFC based Document-View-Application with a CHTMLView hosting a IWebBrowser-Control. Futhermore I implemented an Event Sink based on a CCmdTarget to listen to MouseMove-Events (HTMLDocumentEvent) within the Browser-Control. This works fine for websites not working with frames. When I work with frames I only get connected to the frame-document itself.
Any help is truly appreceated.

I am new to COM. I am developing an application using COM. I got the error as: error LNK2001: unresolved external symbol _CLSID_WMRMKeys. What I know is that the com object is from a DLL, and I registered the DLL by running regsvr32 *.dll, and the registration is successful. Thanks for your help.

I presume you have included the header file for the dll in your application and everything looks fine until you link. I would recommend if you are new to com that you use the #import directive to access the dll's functionality (see MSDN) for more information.
The alternative would be to use include the yourdllsname_i_.c stub file in your project. Turning off precompiled headers on that file otherwise you'll get a weird "stdafx" not found error.
Using #import would be easier but ...

Hi Forum!
this is Shatrughan Mishra. I am thankfull to
you all as many like me would have been for the articles posted by you on
codeproject.com.
I have been trying to add two addins to the MS word 2000 and XP. Both
are working fine independently. But, the problem is when I try to add
both of them the one is overridden by the other and both produce the
same result. I also would like to learn about the mystery of ".dot".
Please guide me and help me solve my problem. If you charge anything for
this, I would be glad to pay for it.
Thanx in advance!
Regards!
Shatrughan.

Are the two add-ins using the same original code? I mean, did you create one project and made two copies, and changed the code in both the copies to create two add-ins?
If you did the above, then it will not work, as the GUID is the same for both. Then you should create new GUIDs using the GUIDGen.exe utility, and use them in at least one of the projects, so that they do not conflict.
And about the ".dot" stuff, sorry, I have never worked with that.
this is this.

There is an application with hosted Internet Explorer (WebBrowser). I have a problem with customizing
IE preferences. They are to be customized only for an instance of Internet Explorer without affecting
global preferences stored at HKCU\Software\Microsoft\Internet Explorer.
1. I need to specify default page, colors, CSS styles and font size. I use
IDocHostUIHandler::GetOptionKeyPath to specify registry path with custom preferences:
STDMETHODIMP rbDHTMLBridge::GetOptionKeyPath(BSTR __RPC_FAR *pbstrKey, DWORD dw)
{
MessageBox(NULL,"GetOptionKeyPath", "GetOptionKeyPath", MB_OK);
static LPCWSTR lpwszKey = L"Software\\MyApp";
if ((*pbstrKey = (LPOLESTR)CoTaskMemAlloc((wcslen(lpwszKey) + 1) * sizeof(OLECHAR))) != NULL) {
wcscpy(*pbstrKey, lpwszKey);
} else {
return E_INVALIDARG;
}
return S_OK;
}
Function is called by IE and returns S_OK. But it does not affect hosted IE: it uses global
preferences.
Why it didn't work? May be I missed some initialization?
2. I need to remove footer and header of HTML pages printed using hosted IE. It can't be done
by GetOptionKeyPath (Internet Explorer uses global preferences for footer and header in any case).
It can be done by WebBrowser.ExecWB(OLECMDID_PRINT, ...) as described in
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q267240. I copied code from this article into
my application but it didn't work. Footer and header from original page were used on the printed page.
Why it didn't work?
May be the reason is what i have IE6.0 but the highest version of IE in APPLIES TO section of the article is 5.0?
Any help will be appreciated.

Hello,
I was wondering if it is possible to implement MDI in a MFC based ActiveX control. I was able to implement SDI (using a sample from MSDN), but I faced some difficulties when implementing MDI. Any help would be highly appreciated.
Thanks in advance,

Hi,
I want to pass the reference(test) of the interface (ITest) define inside the COM DLL (TestCom.dll) in my application function.Example
GetMerchItemType( TestComLib::ITest &test, int Temp)
However I am facing the following error.
error C2653: 'TestComLib' : is not a class or namespace name
error C2061: syntax error : identifier 'ITest'
Can you please help me resolve this error.
Thanks

Check the spelling.
If you haven't explicitly renamed the namespace it would look something like 'TESTCOMLib'.

Hi everybody
I got some problems by using an application under Windows NT 4.0, this application uses OPC and it seems it's causing this kind of problem... it says RPC system not initialized... another weird thing is the request of the missing OCX of WinSock "mswinsck.ocx" that should come with the system (I took one on Win2K and registered by my own using REGSVR32... but I'm not sure it's a great idea...). If somebody know anything that may help please tell me!!!
Thanx

Hi, friends
I tried to build a dll which support COM self-regist using Visual C++ 6.0. I used a API, named LoadTypeLib, to load the dll's typelib:
...
CComPtr<itypelib> pTypeLib;
HRESULT result = LoadTypeLib(module,&pTypeLib);
...
The variable "module" is the DLL's full path name. For example, I use "D:\\temp\\test\\test.dll". But, the return value "result" always is 0x80029c4a (TYPE_E_CANTLOADLIBRARY). If I use "D:\\temp\\test\\test.tlb" as the value of "module", this function should return 0x00000000(S_OK).
I have import "test.tlb" into the resource of test.dll. So I don't know how to resolve this problem.
Thanks a lot!

Hello smallbluedemon,
1. Make sure that you have set the resource type to be "TYPELIB" and have also set the resource ID to be 1.
2. Try out the following function to load your resource-embedded type library binary :
HRESULT MyLoadTypeLibrary(ITypeLib** ppITypeLibReceiver)
{
TCHAR szFileName[_MAX_PATH];
memset (szFileName, 0, sizeof(szFileName));
GetModuleFileName
(
(HMODULE)NULL,
(LPTSTR)szFileName,
(DWORD)sizeof(szFileName)
);
// Need to concatenate a \1 to the end of the filename
// because we are acquiring the type library which is
// embedded as the 1st resource of type TYPELIB.
strcat (szFileName, "\\1");
return LoadTypeLib((const OLECHAR FAR*)_bstr_t(szFileName), ppITypeLibReceiver);
}
Use it in your code this way :
int main(int argc, char* argv[])
{
CComPtr<ITypeLib> pTypeLib;
MyLoadTypeLibrary(&pTypeLib);
return 0;
}
Pls let me know how things go 
Best Regards,
Bio.

Hello, Bio.
Thank you very much!
By your suggestion, I found my mistakes. In my resource header file "resource.h", I set following macro:
#define IDR_TYPELIB 199
But, I forgot to add this to file name. I add your statement:
........
GetModuleFileName(hInstance, ansiPath, MAX_PATH);
strcat(ansiPath,"\\199");
MultiByteToWideChar(CP_ACP, 0, ansiPath, strlen(ansiPath) + 1,module, MAX_PATH);
.......
Problem resolved !
Thank you again. Thank you very much!
Your sincerely
Remy (smallbluedemon)

I recently developed a .Net 2003 Windows Application that posts xml documents to a URL using XMLHTTP methods (required by vendor). I have not found any reference of XMLHTTP for the Net platform, but did find out that the methods are exposed through the MSXML library, so I added in my project a reference to the Interop msxml2 dll and used the methods. The application runs very well on my Visual Studio 2003 IDE, but when I moved the dll's to the server, it gives me the following exception:
System.Runtime.InteropServices.COMException (0x800C0008): The download of the specified resource has failed. at MSXML2.XMLHTTPClass.send(Object varBody) at ttHTTPWebclient.ttHttpWebClient.SendHttpRequest(String st
I don't know much about COM and have no idea what this error means. Could not find info about it on the net either, so I decided to try this forum.
Here is my code:
Public Function SendHttpRequest(ByVal strServiceURL As String, ByVal xmlMessage As String, Optional ByVal Mode As String = "msg") As String
Dim strResponse As String
Dim xmlhttp As New MSXML2.XMLHTTP
Dim xmlDocRQ As New MSXML2.DOMDocument
Dim xmlDocRS As New MSXML2.DOMDocument
Dim xmlLenght As Integer
Dim root As MSXML2.DOMNodeType
Try
'///////////////////////////////////////////////////////////////////
'// Createthe HHTP Post quote request //
'///////////////////////////////////////////////////////////////////
'Initialize Dom Variables
xmlLenght = xmlMessage.Length
xmlDocRQ.async = False
xmlDocRQ.loadXML(xmlMessage) 'Load xml Msg vendor request into a DOM
xmlhttp.open("post", strServiceURL, False, "ESPTest1", "4zz8ygh7mkka")
xmlhttp.setRequestHeader("Content-type", "text/xml; charset=utf-8")
xmlhttp.setRequestHeader("Content-length", xmlLenght)
'///////////////////////////////////////////////////////////////////
'// Send the Post request and get the response from the vendor //
'///////////////////////////////////////////////////////////////////
xmlhttp.send(xmlDocRQ)
xmlDocRS = xmlhttp.responseXML
strResponse = xmlDocRS.xml
'///////////////////////////////////////////////////////////////////
'// Return response to the calling method //
'///////////////////////////////////////////////////////////////////
Return strResponse
Catch ex As Exception
Dim strex As String
strex = ex.ToString()
Return strex
End Try
Any help will be greatly appreciated. I can not use normal POST messages because the authentication (userid/Password) can not be part of either the URL (query string) or the actual xml message being posted, per vendor requirement (owner of the page I am posting to) .
Regards,
Ivan

hello,
I am a newbie when working with COMs and dlls. I have written an application in VC++, and wanted to add one more functionality in the form of a function. Now this is additonal functionality is actually done by a VB team in the form of a .dll made in VB 6.
How can I import the function from that .dll to use in my application? Is there any tutorial available which addresses this issue?
Please let me know.
Thanks

There is a activex written using MFC and COM .
The main class inherits
CComObjectRootEx
IDispatchImpl
CComCoClass
IObjectSafetyImpl
Now 2threads are created inside this class in the constructor.
When IE is refreshed/reloaded, I loss the pointer of the process and
threads are not deallocated.
So what I did is, made thread ID's as static in the class and
deallocate them in the constructor before creating new threads.
When I WaitforSingleObject() I always get time out(258).
so I call TerminateThread().
I know this is wrong way.
Now this method is leaving lot of leaks.
Please suggest me a remedy so that I can trap the refresh ask my thread
to exit gracefully.
Thanks a lot in advance.

Hello.
I know how to send longs, ints, booleans, (basic types) between a COM component and a client using VARIANT.
However, how do I send a user defined object using VARIANTs as well?
Is it possible?
Could you post please a small source code example?
THANK YOU

I have written a COM service using ATL 7.0 and VS 2003 which contains one COM Class. The class uses a number of member variables, some of which are CComBSTRs. Clients can use the get/put methods on these strings. The strings are processing parameters for calls to the calculation operation in the COM object. The string variables are changed to alter the output each time the object is called. Sometimes, the result of the get function is not what was sent to the put function.
Server Code:
<br />
CComBSTR m_bstrTheString;<br />
<br />
m_bstrTheString = SysAllocString(L"Testing");<br />
<br />
[propget, helpstring("property m_bstrTheString")] HRESULT m_bstrTheString([out, retval] BSTR* pVal);<br />
[propput, helpstring("property m_bstrTheString")] HRESULT m_bstrTheString([in] BSTR newVal);<br />
<br />
STDMETHOD(get_m_bstrTheString)(BSTR* pVal);<br />
STDMETHOD(put_m_bstrTheString)(BSTR newVal);<br />
<br />
STDMETHODIMP CMyClass::get_m_bstrTheString(BSTR* pVal)<br />
{<br />
*pVal = m_bstrTheString;<br />
return S_OK;<br />
}<br />
<br />
STDMETHODIMP CHunter::put_m_bstrTheString(BSTR newVal)<br />
{<br />
size_t s = ::SysStringLen(m_bstrTheString);<br />
if(s > 0)<br />
::SysFreeString(m_bstrTheString);<br />
m_bstrTheString= ::SysAllocString(newVal);<br />
return S_OK;<br />
}<br />
In the client code(simplified):
<br />
BSTR bstrIn;<br />
BSTR bstrOut;<br />
<br />
HRESULT hr = CoInitialize(NULL);<br />
CT2CW szIn(argv[3]);<br />
bstrIn = ::SysAllocString(szIn);<br />
if(bstrIn == NULL)<br />
return E_OUTOFMEMORY;<br />
MyService::IMyPtr pMine(__uuidof(MyService::CMy));<br />
hr = pHunter->put_m_bstrTheString(bstrIn);<br />
hr = pHunter->get_m_bstrTheString(&bstrOut);<br />
My question is: Is this a good way to go about this. I am having the problem of the string sometimes being overwritten by other variables of the same type when performing operations on them.
Thanks in advance for any help.
Rob

CComBSTR does all the SysAllocString stuff for you.
Try this instead:
<br />
CComBSTR m_bstrTheString;<br />
<br />
m_bstrTheString = L"Testing";
<br />
[propget, helpstring("property m_bstrTheString")] HRESULT m_bstrTheString([out, retval] BSTR* pVal);<br />
[propput, helpstring("property m_bstrTheString")] HRESULT m_bstrTheString([in] BSTR newVal);<br />
<br />
STDMETHOD(get_m_bstrTheString)(BSTR* pVal);<br />
STDMETHOD(put_m_bstrTheString)(BSTR newVal);<br />
<br />
STDMETHODIMP CMyClass::get_m_bstrTheString(BSTR* pVal)<br />
{<br />
*pVal = m_bstrTheString.Copy();<br />
return S_OK;<br />
}<br />
<br />
STDMETHODIMP CHunter::put_m_bstrTheString(BSTR newVal)<br />
{<br />
m_bstrTheString= newVal;<br />
return S_OK;<br />
}<br />
