How to create a new thread to init socket in DLL?

I hava writen a DLL,and injected DLL into a process.But when I inject DLL into target process every time,it will terminate the target process.If I don't create a new thread in DLL,it work well.How can I write correct code to implement?
ps: testdll.cpp
#include "stdafx.h"

#include <afxdllx.h>

#include "process.h"

#ifdef _DEBUG

#define new DEBUG_NEW

#endif

static AFX_EXTENSION_MODULE TestDLL = { NULL, NULL };

unsigned __stdcall ThreadFunc(LPVOID pParam){

CSocket sockListen,m_sockSend;

sockListen.Create(6802,SOCK_STREAM,"127.0.0.1");

sockListen.Bind(6802,"127.0.0.1");

sockListen.Listen(5);

sockListen.Accept(m_sockSend);

Sleep(50000);

sockListen.Close();

MessageBox(NULL,"ThreadFunc","Oops!!",MB_OK);

return 0;

}

extern "C" int APIENTRY

DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)

{

UNREFERENCED_PARAMETER(lpReserved);

if (dwReason == DLL_PROCESS_ATTACH)

{

TRACE0("Test.DLL ！\n");

if (!AfxInitExtensionModule(TestDLL, hInstance))

return 0;

new CDynLinkLibrary(TestDLL);

_beginthreadex(NULL,0,ThreadFunc,NULL,0,NULL);

}

else if (dwReason == DLL_PROCESS_DETACH)

{

TRACE0("Test.DLL ！\n");

AfxTermExtensionModule(TestDLL);

}

return 1;

}

Hi all!
I have a problem in getting xml file data. If a xml file is in my computer, i can get all data. But if i want to access to another computer to get data, all of it will be NULL. My code is here: (unicode project)

// redefine : using msxml3.dll
typedef MSXML::IXMLDOMDocument* XMLDocumentPtr;
typedef MSXML::IXMLDOMElement* XMLElementPtr;
typedef MSXML::IXMLDOMNode* XMLNodePtr;
typedef MSXML::IXMLDOMNodeList* XMLNodeListPtr;
XMLDocumentPtr pXMLDoc = NULL;
HRESULT hr;
hr = CoInitialize(NULL);
if (FAILED(hr)) {
return FALSE;
}
hr = CoCreateInstance(MSXML::CLSID_DOMDocument, NULL,
CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER,
MSXML::IID_IXMLDOMDocument, (LPVOID*)&pXMLDoc);
if (!pXMLDoc) {
return FALSE;
}
pXMLDoc->put_async(VARIANT_TRUE);
VARIANT_BOOL varOkay;
pXMLDoc->load((_variant_t)szXMLFilePathName,&varOkay);
if(!varOkay)
return FALSE;
XMLNodePtr pNodeItem = NULL;
VARIANT var;
CString szTmp;
// get Version
szTmp = _T("VisioAlertData/VersionAlert/Version");
pXMLDoc->selectSingleNode((_bstr_t)szTmp, &pNodeItem);
if(pNodeItem)
{
pNodeItem->get_nodeTypedValue(&var);
vAlt.m_szVersion = var.bstrVal;
} .............

If szXMLFilePathName = _T("C:\\a.xml") then pNodeItem will be != NULL
But if szXMLFilePathName = _T("http://pnlong:8080/Visioalerte/VisioAlerte.xml") then pNodeItem will be = NULL. but if after pXMLDoc->load((_variant_t)szXMLFilePathName,&varOkay) i call a message: AfxMessageBox(szXMLFilePathName) then i can get all data.

I don't know why D'Oh! | :doh:

. Who can help me?
Thank in advance!

An edit box is a pretty interesting control. It paints itself outside of WM_PAINT, which makes owner drawing one challenging, and I would thing that owner drawnig one in an unusual shape would be doubly so.

Not exactly an Edit control but I'm sure you can apply the same principle http://www.codeproject.com/dialog/SimpleIrregular.asp[^]

Edit Control multiline - number of lines

Dear friends,
How can I know how many lines of text in the Edit control?
I want the edit control to scroll vertically to the last line of the text.
I want to know the number of lines (nLines) in Edit ocntrol so I can use CEDIT::LineScroll(nLines).
thanks and Cheers,
Joy Anne

One way could be:
You can use CString::Find method to check if the string in the edit box contains a \n. If it contains just increment the count by 1 and so on.....

Somethings seem HARD to do, until we know how to do them.

use CEdit::SetSel() and place the caret after the last character...

That does not give you the line number, however. You'd have to then call CEdit::LineFromChar() to get the line number (minus one).
