Hi all,
I am developing a Win32 Console application that reads XML file and displays the data. I am importing msxml4.dll and then usiing the following code to create the instance of the DomDocument class
HRESULT hr;
IXMLDOMDocumentPtr pDocument = NULL;
IXMLDOMParseErrorPtr pParseError = NULL;
BSTR bstr = NULL;
VARIANT_BOOL status = NULL;
VARIANT vsrc;
CoInitialize(NULL);
hr = CoCreateInstance(CLSID_XMLDocument,NULL,_ CLSCTX_INPROC_SERVER,IID_IXMLDocument,(void**)&pDocument);
VariantInit(&vsrc);
V_BSTR(&vsrc) = SysAllocString(L"try.xml");
V_VT(&vsrc) = VT_BSTR;
hr = pDocument->load(vsrc,&status);
hr = pDocument->Getxml(&bstr);
cout << "Try.xml comtents: " << bstr;
if(bstr)
SysFreeString(bstr);
if(&vsrc)
VariantClear(&vsrc);
if(pParseError)
pParseError->Release();
if(pDocument)
pDocument->Release();
CoUninitialize();
when I compiled the program it gives error
'Getxml' : is not a member of 'IXMLDOMDocument'
when I run the application without calling getXML function it gives me run time error that unhandled exception in the application.exe 0xC0000005: Access Violation.
Can anyone tell me where I am wrong.
I ahve the following files in system folder
msxml2.dll,msxml2r.dll,msxml3a.dll,msxml3.dll.msxml3r.dll.msxml4.dll,msxml4r.dll.msxmlr.dll
One point where I suspect error could be as to crete instance using CLSID_DOMDocument40, IXMLDOMDocument4 but in my project it gives me error when I call the CoCreateInstance with the above mentioned parameters.
Thanks in advance.

Instead of GetXml() simply use IXmlDomDocument::xml variable. it is BSTR variable which contain whole XML file which is currently loaded in interface.
Anyway from where you got this example Code!

Hi Alok,
Error in the CoCreateInstance is still the same. Error is
D:\Ritu\VC++\Win32XML\xmlsource.cpp(20) : error C2065: 'IID_IXMLDOMDocument' : undeclared identifier

Hi Alok,
The type of errors are still same. Errors are:
error C2039: 'loadXml' : is not a member of 'IXMLDOMDocument'
error C2039: 'xml' : is not a member of 'IXMLDOMDocument'
error C2039: 'GetnodeName' : is not a member of 'IXMLDOMNode'
error C2039: 'GetnodeName' : is not a member of 'IXMLDOMNode'
error C2039: 'GetnodeValue' : is not a member of 'IXMLDOMNode'

Hi Alok,
Including msxml2.h does not make any difference. Right now I am downloading MSXML 4.0 SP2. It may change the scenario.
But to run the XML from visual basic we don't need to install MSXML4.0. Just registering the dlls are sufficient.
Do we really need to install MSXML4.0 for VC++ ??? I think if we have the DLLs then it should run in the proper way.

There is theoretically no difference in COM programming in both VB and VC.
If some COM dll run in vb then it defiantly run in VC, that’s the power of COM!

Actually MSXML SKD provide you -> documentation, sample source code and msxml4.h. it's upto u what do u need

Just by registering the proper dll makes your program work properly.

Hi
I have an application which runs a timer synchronously. I think I have a bug in the timer. Can I find out the bug with the VC++ debugger or should I go for any other tools. Please help with ideas.

Hello,
I have a C++ dll that I just created and im having trouble converting the data inside a BYTE * to a C# version of byte[].
On my C# App I DllImported the dll, the return type i set to be an IntPtr (the return type of the C++ dll is BYTE *)
I then put the IntPtr I then Marshaled it and put the results inside a MemoryStream.
The output should have been an image (bitmap). but when trying to save to file it gives an error of not valid type.
My question is, on the C++ dll, what type is BYTE *? on my C# side should I go int, Uint32, IntPtr??
Any help would be greatly appreciated.

Did I create a tough question?
Does anyone know what to Marshal the BYTE * to on the C# side?

i've tried everything i can think of, but can't seem to capture a double-click in my CSliderCtrl-derived class.
i've tried ON_WM_LBUTTONDBLCLK, ON_WM_NCLBUTTONDBLCLK, PreTranslateMessage and even WindowProc , but none of them respond to double-clicks.
i've looked at the source for the control, but there's not much there (it's a common ctrl, so the bulk of the implementation is probably in COMCTRL32.DLL).
so, anyone else ever managed to capture dblclicks on a slider ?

I still think that you should have gone with my suggestion - which was to have one menu and only show valid options.
Where does it crash ? Perhaps if you posted the full code ( at the moment, what you're including is missing ), someone will post it into a project and try to work out what's going wrong, but it would be more helpful if you told us.

Well i wanted to go with your suggestion but then i have the program crushing and i have already intergrated my code it is now large. But even the submenu one that i am thinking above cannot confuse user's of the system if it is used.

First trick of programming - if it crashes, work out why, don't just change to a lesser design 
To reiterate - where/why does it crash ? I assume that crush == crash ?

I keep hoping that at some point you will either check the 'Do not treat <'s as HTML tags' box so that your includes come out in your post, or you'll stop just posting all the code over and over, and actually tell us what's going wrong/what error messages you get/etc.
