Hello everyone,
I need to make Application that uses IShockwaveFlash, could anyone help me on how to check if flash.ocx (or whatever it uses) is installed, and if installed what version is installed?

try
CLSIDFromProgId(L"ShockwaveFlash.ShockwaveFlash", &clsid);
if this function is SUCCEEDED then flash is installed. Also CoCreateIstance can be tried to make sure.

I suspect you are using WTL's version of CString. Dump the atlmisc.h, and include atlstr.h instead, to use ATL's version of CString. It might also do you some good if you upgraded WTL too. Smile | :)

You should ask in the XML Forum[^], not in here.

However, to save your first post being a copy of this, here's a few things to get you started.

In your stdafx.h file (or whatever you're using as a precompiled header) put

#import <msxml.dll> rename_namespace("MSXML") raw_interfaces_only named_guids

That will give you declarations for the various MS XML interfaces and such.

Secondly, you need to instantiate a document. Here's where it's a little tricky, since you have to know what version of MSXML you want to use.

CComPtr<MSXML::IXMLDOMDocument> spDoc;
HRESULT hr;
CLSID clsid;
if (SUCCEEDED(::CLSIDFromProgID(L"MSXML2.DOMDocument.3.0", &clsid)))
{
hr = ::CoCreateInstance(clsid, NULL, CLSCTX_ALL, MSXML::IID_IXMLDOMDocument, reinterpret_cast<void**>(&spDoc));
if (SUCCEEDED(hr))
{
// Yay, we have a document object!
}
}

Once you have one of those, you can load it

VARIANT_BOOL bLoaded = VARIANT_FALSE;
hr = spDoc->load( _variant_t(sourcefile), &bLoaded);
if (SUCCEEDED(hr) && bLoaded)
{
// Your document is loaded, use MSXML methods to interrogate the DOM document
// and extract your data...
}

MSDN has lots of information on IXMLDOMDocument and the other related interfaces, so dig around in there, or ask questions in the XML forum.

VB.But it can‘t show rightly when I insert it to the word document.

About my ocx : A project based MFC ActiveX Wizzard , I placed a CSlider

Following things I done so that I stop getting errors.
1) Copied WTL folder at various places
2) Copied WTL files in VC98, and many combinations.
3) I installed WTL wizard
4) Tools --> options I included, directories ,libraries etc

It gives errors in bunch for CString ,IXMLDOMDocument and upto 103 same.
if any one know how to link WTL.

What version of Visual Studio are you using?
Have you tried building a new test application?

Are you including atlmisc.h? That's where CString is defined. You typically include this in stdafx.h.

Patience is a virtue; do you think we have nothing better to do than answer questions all day?

Before you include any WTL headers, try

#define _WTL_USE_CSTRING

This tells WTL to define and use it's own CString implementation, instead of relying on the MFC one. If you have VC7 or later (which you apparently don't), CString doesn't really need the rest of MFC.

Dear Friend
Did you noticed problem is not with only CString. It is giving problem with

d:\mrutyunjaya\xmlload\xmldom.h(82) : error C2065: 'IXMLDOMDocument' : undeclared identifier
d:\mrutyunjaya\xmlload\xmldom.h(82) : error C2955: 'CComPtr' : use of class template requires template argument list
c:\program files\microsoft visual studio\vc98\atl\include\atlbase.h(563) : see declaration of 'CComPtr'.

Thanks for CString suggestion I will try that.

Well, the file producing the errors isn't a standard one, but my guess is that you're not including an MS supplied file, like msxml.h or something, since that would define IXMLDOMDocument. In any case, this latter issue is nothing to do with WTL.

Urgent:memory leak in recursion with CComPtr

rana7410-Jul-06 22:08

10-Jul-06 22:08

I have a recurive loop where each element has to get its parent and retrieve the property
CComPTR<ihtmlelement> spElem=....
.........
........
.......
IHTMLElement* spParentElem=NULL;
while (1)
{
CComBSTR bsTagName;
spElem->get_tagName(&bsTagName);
std::string thisods=ODSTag;
ODSTag=OLE2A(bsTagName);
if(thisods.size() > 0)
{
ODSTag+= ".";
ODSTag+=thisods.c_str();
}

hr = spElem->get_parentElement(&spParentElem);===>memory leaks here
if (FAILED(hr) || !spParentElem)
break;
spElem.Detach()->Release();
spElem=NULL;
spElem = spParentElem;

}

I am getting massive memory leaks in the line above.What am i doing wrong here?Any help or advise would be appreciated.Thanks in advance.

Re: Urgent:memory leak in recursion with CComPtr

Firstly if you use the "sp" prefix, which generally stands for "Smart Pointer", the variable in question should actually be a smart pointer. i.e.

CComPtr<IHTMLElement> spParentElem;

Don't write misleading code.

Make your code like this:

CComPtr<IHTMLElement> spParentElem;
while (1)
{
    CComBSTR bsTagName;
    spElem->get_tagName(&bsTagName);
    std::string thisods=ODSTag;
    ODSTag=OLE2A(bsTagName);
    if(thisods.size() > 0)
    {
       ODSTag+= ".";
       ODSTag+=thisods.c_str(); 
    }
 
    spParentElem.Release(); // FREE THE OLD ONE!
    hr = spElem->get_parentElement(&spParentElem);===>memory leaks here
    if (FAILED(hr) || !spParentElem)
    {
       break;
    }
    spElem.Detach()->Release();
    spElem=NULL;
    spElem = spParentElem;
}

The addition is shown in bold.

I'm going to finish with a bitch. We can't see any "<"s or ">"s or what's between them: this is important in C++ code. Also there is no formatting. Please make an effort to make things easier for the people who are taking time to help you. At the very least you could tick the "Ignore HTML tags in this message (good for code snippets)" check box.

PS: I can see iteration here but no recursion.

Get Frame window Handle

HakunaMatada10-Jul-06 17:58

HakunaMatada

10-Jul-06 17:58

I have an SDI application. This SDI application has a Splitter control, which has Pane controls and the pane controls themselves have other child controls. So, there is a hierarchy of controls. Now, If I have the handle of any child control, I want to get the Handle of the SDI application window. Is there any way to achieve this?

GetParent() may work, but I would certainly not know how many GetParent()s I am supposed to call. For Example, if I have the HWND of the PaneControl, I would have to call GetParent() twice. One for the Splitter control and the other for the application Window. Similarly, if I have the handle of the Splitter control, I would have to call GetParent() only once. This is the why I think GetParent() is not such a good idea. Any other options?
