Re: CSocket crashes program inside thread

That article deals with passing a socket to a thread.

What I'm trying to do is create the socket inside the thread.

I can detect that the thread is being run, but the moment
I call Create, it crashes the program.

I get the following stack :

CMapPtrToPtr::GetValueAt(void * 0x00000744) line 179 + 3 bytes

unsigned int nPort = 0x7e00;
volatile unsigned char *exAddress;
exAddress =(volatile unsigned char *) nPort;

Best regards.

Anyone has any clue what could be causing this ?

Message from VC++ 6.0 linker
error LNK2001: unresolved external symbol __imp__AlphaBlend@44

I'm starting to think this project is jinxed. First my little property headache and now this one.

Thanks for any input.

Thanks, that did it.

Funny thing is I have a another project that uses this and I don't ever remember having to do this. Oh well, maybe I just forgot about it.

Again, thanks for your help.

Hiding the scroll bars in a IE ActiveX control window

Rezwan Haque11-Mar-05 5:04

Hi There,
I am using the Microsoft Web Browser ActiveX control component in a
a dialog container to display a web page in Visual C++ 6.0. Basically the web page
on the server is small rectagular area and thus the full IE acreen
area is not required. Despite disabling the member variable's for the
WebBrowser class Horizontal and Vertical scroll bars through EnableScrollBarCtrl
the Web container page produces a greyed out disabled scroll bar. Is there
any way over riding this and preventing it being displayed. Do I have to access
the COM interfaces and set the property that way.

Regards
Rezwan

Dear (whatever you want),

I have two questions:

1. I'm trying to make an active Document Server application in MFC in the VS2003.
The problem is that I don't have any MFC experience and I'm just longing for some easy programming with those arraylists and window forms. I think I could link my MFC project and my Managed C++ (or C#) with a CCW.
The question: Any hints or tips? Smile | :)

2.
The question: Is this the right discussion board?

thanks,

Paul

I would love to have a funny signature

I HAVE CREATED A XML USING IXMLDOMDOCUMENT.NOW I WANT FETCH A NODE . WHICH FUNCTION IS USED TO FETCH A NODE

Re: IXMLDOMDOCUMENT

let consider your XML to be something like this

<xml>
   <cp>
    <article>visual c++ is best</article>
    <author>best</author>
   </cp>
   <cp>
    <article>learning VC</article>
    <author>Mes</author>
   </cp>
</xml>

Now Assume you loaded it into your interface
IXMLDOMDocument object say pXmlDom

now for enumerating the data/node inside the XMLObject Read this little piece of code.

<font color=#008000>//First get NodeList</font>
 CComPtr<MSXML2::IXMLDOMNodeList> pNodeList=NULL;

<font color=#008000>//if you are wroking in MFC</font>

 CStringArray arrArticleName,arrAuthor;
<font color=#008000>//if you are in ATL comment above line and use this line
// CSimpleArray<CString> arrArticleName,arrAuthor;</font>




  pNodeList=pXmlDom.getElementsByTagName(L"cp");

 USES_CONVERSIONS;<font color=#008000>//for String conversion MACROS</font>


<font color=#008000>//check is we got the list successfully</font>

if(pNodeList)
 {
<font color=#008000>  //yeah we got something
  //Now enumerate the DATA</font>

  for(long i=0;i<pNodeList->Getlength();i++)
 {
<font color=#008000>   //Get Book Name</font>

  arrArticleName.AddString(W2T(pNodeList->Getitem(i)->selectSingleNode(L"article")->text));
<font color=#008000>   //Get Author</font>

 arrAuthor.AddString(W2T(pNodeList->Getitem(i)->selectSingleNode(L"author")->text));
 
  }
 }

Now arrAuthor, arrArticleName will contain the data of nodes
