Hi,

I used to see a drop down in my visual studio editor(using vc++) which would list out all the classes in the file and the second dropdown would have the listings of all the methods.

While doing something, those two dropdowns have gone missing, can anybody help me to browse the menu options and add them back into my visual studio.

Thanks,

are you using visual C++ 6 or .NET 2003 ?

if you're using VS.NET, you will find those comboboxes heading the source files (when you open one...).

cheers,

Might sound quite silly, but I am not able to see the wizard bar. Looked at the customize option to see whether its missing, but could'nt really find it.

THanks,

The Wizard Bar is only available in VS6.
Since you are using the .NET studio, you can activate the drop down combos by :

Tools->Options->Text Editor->C/C++->Navigation Bar

I found that the navigation bar option is checked. Relaunched the visual studio but not able to see the combos.

Get yourself the microsoft directx 9 sdk[^] and look @ the 'CaptureSound' sample.

Hi,

I have this project. It is an installer with the following requirments:

1. Enumerate COM Ports and prompt the user to select one to use for a modem.
2. Then programatically install the modem on the COM port selected from either a unimodem .inf file or a Nokia 2285 .inf file without any intervention again.

I need your assistance (even if commercial in nature) to accomplsh this in C/C++ or VB.

Best regards.

XML file traversal ????

Ritu Kwatra10-Apr-05 21:27

10-Apr-05 21:27

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,
I tried accessing XML variable also but the error is same that is
'xml' : is not a member of 'IXMLDOMDocument'

and I got the example on the msdn site
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/dom_hdi_cpp_getready.asp[^]

The difference in my code is in the CoCreateInstance statement. When I use CLSID_DOMDocument30(as in the msdn example) then it gives me the following error

'CLSID_DOMDocument30' : undeclared identifier

Here is small example,hope that's work for you.

MSXML2::IXMLDOMDocument *l_pXMLDomDocument;
MSXML2::IXMLDOMElement  *l_XMLDomElemnent;
MSXML2::IXMLDOMNode  *l_XMLDomFirstNode,*l_XMLDomNextNode;

CLSID clsidXMLDom;
	
::CLSIDFromProgID(OLESTR"msxml2.domdocument"),&clsidXMLDom);

	
	if(SUCCEEDED(CoCreateInstance(clsidXMLDom,NULL,CLSCTX_ALL,IID_IXMLDOMDocument,reinterpret_cast<LPVOID*>(&l_pXMLDomDocument))))
{
	//Object creation successful
	MessageBox("Object Creation successful");
}

CString strXml="<xml><cp>helloo</cp></xml>";
l_pXMLDomDocument->loadXml(_variant_t(strXml.AllocSysString()));

MessageBoxW(NULL,l_pXMLDomDocument->xml,L"XML",MB_OK);

 l_pXMLDomDocument->get_firstChild(&l_XMLDomFirstNode);

 MessageBoxW(NULL,l_XMLDomFirstNode->GetnodeName(),L"",MB_OK);

l_XMLDomFirstNode->get_firstChild(&l_XMLDomNextNode);

 CString str;

while(l_XMLDomNextNode)
 {
 MessageBoxW(NULL,l_XMLDomNextNode->GetnodeName(),L"",MB_OKCANCEL);

 l_XMLDomNextNode->get_firstChild(&l_XMLDomFirstNode);

 while(l_XMLDomFirstNode)
 {
 MessageBoxW(NULL,l_XMLDomFirstNode->GetnodeName(),l_XMLDomFirstNode->GetnodeValue().bstrVal,MB_OK);

 l_XMLDomFirstNode->get_nextSibling(&l_XMLDomFirstNode);

 }
		  

 if(l_XMLDomNextNode->get_nextSibling(&l_XMLDomNextNode)==S_FALSE)
	 l_XMLDomNextNode=NULL;

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
