I have added the function but still did not work..
When I press test button on dialog, it works and seems ok.
got any idea??? 
<br />
BOOL Appl::InitInstance()<br />
{<br />
AfxOleInit();<br />
<br />
Works fine using AfxEnableControlContainer
Here's what msdn says about it:
If you did not enable ActiveX control support when you used AppWizard to generate your application, you will have to add this support manually. This article describes the process for manually adding ActiveX control containment to an existing OLE container application

Helo,
I m writing win32 client socket using openssl.
my code for receive is like
static int lsSocketRecv(SSL* ssl, char* buf, int len)
{
int nRecv = 0;
char* p = buf;
int nRest = len;
do {
//nRecv = recv (sock, p, nRest, 0);
nRecv = SSL_read (ssl, p, nRest);
if (nRecv < 0)
{
printf("error");
}
}
when my control come to SSL_read(), it will blocks there only.
I mean control is not going ahead from SSL_read().
I already add all dependency regarding openssl and I m able to sucessfully connect with the server.
one more thing is that is there any way so that i can make it nonblocking mode in SSL.
Regards,
Amit

How can I do this?

Hi,
I am trying to understand "__declspec(thread)" and where it is declared
My situation is I have a DLL which is implicitly bound (hope that is the right term) many threads access the DLL
I do some processing in the DLL_THREAD_ATTACH message
Lets say I declare a pointer with __declspec(thread) attribute in the Global Section of the DLL
e.g. __declspec(thread) char *thread_ptr;
In the process that calls the DLL there exists a function which is multithreaded (many threads execute this function)
lets call it funca() How do I access thread_ptr in funca or better yet how do I declare it
e.g. extern __declspec(thread) char *thread_ptr not sure
|
|
|
|
|
see the guidelines in the remark section of [__declspec( thread ) declarator^]
how ever your example is correct, extern keyword is not required if the declaration is in the same file of funca() definition
|
|
|
|
|
I guess the Linker would know that the __declspec(thread) char *threadptr in the DLL and the__declspec(thread) char *threadptr in main->funca() are one and the same if the DLL is implictly (hope that is the right term) Loaded by the process/.exe

I am not very mych expert in VC++. i need to draw some airplane like shape and need to move it. or simply just moveit to new coordinates. right now i am generating the new coordinatees and drawing a circle in the new position. but i need to dwaw some 2 d aircraft like shape.
here is a part of my code
for (i=0;i<m_SizeOfArray;i++)
{
GraphRegion->Ellipse(Points[i].x-5,Points[i].y+5,5+Points[i].x,Points[i].y-5);
}
it generates circle in new positions.or can anyone tell me how u can load an image to new positions.
i badly need the solution.

I guess you can use CDC of your frame. When dragging you image you have to clear it and redraw it in new position. Clear your image by using XOR at same coordinates. Do not clear the entire area for performance.

Mmmm,
If the "plane" is always the same... why don't you try to draw it right first, without movements... then get the first point (let's say the front of the cabine) and take it like "point_start" then base all the other points to this one in a function.
Then a loop with invalidate / erase background and the call to your function with the new "start_point".
an example in "grosso modo":
The static figure
dc.MoveTo (100, 100);
dc.LineTo (125, 125);
dc.LineTo (100, 150);
dc.LineTo (100, 100);
The dinamic function
void draw_shape (int x, int y);
{
dc.MoveTo (x, y);
dc.LineTo (x + 25, y + 25);
dc.LineTo (x, y + 50);
dc.LineTo (x, y);
}
for (int i = 0; i < 10; i++)
draw_shape (0 + i, 100);
Or the other possibility...
You can draw your plane in a bitmap using resource editor, give it a name and then use it with BitBlt
CClientDC dc(this);
CDC dcNewMem;
dcNewMem.CreateCompatibleDC (&dc);
CBitmap bmPlane;
BITMAP bmTemp;
if (bmPlane.m_hObject != NULL)
bmPlane.DeleteObject();
bmNewIn.LoadBitmap (IDB_PLANE);
bmNewIn.GetObject(sizeof(bmTemp), &bmTemp);
dcNewMem.SelectObject(&bmPlane);
dc.BitBlt(x, y, bmTemp.bmWidth, bmTemp.bmHeight, &dcNewMem, 0, 0, SRCCOPY);
}

it is working. but porblem is if the new point is too close then it shows like a line. is there any way to delete the previous shape while i m drawing the same shape in new location.
i need ur help.

To delete previous contents on the screen you can call Invalidate () at the beginning of your function.
I made it in my project coding the OnDraw () function taking the starting point for visible things from the document and, when I wanted to update the window after a function I made:
Invalidate ();
UpdateWindow (); // for active view
// or: pDoc->UpdateAllViews (NULL); //to redraw all opened views although not active
Hope it helps

In OnSize, I wrote like:
m_btn.MoveWindow(&rc,TRUE);
...
Invalidate();

Hi all,
I am making this pauseresume downloader http version:
hOpen = InternetOpen("PauseResumeDemo",INTERNET_OPEN_TYPE_PRECONFIG ,NULL, NULL, NULL);
if(!hOpen)
{
return false;
}
DWORD dwContext = 123;
strStaus.Format("Connecting to server..");
GetDlgItem(IDC_STATIC_STATUSNEW)->SetWindowText(strStaus);
if ( !(hConnect = InternetConnect ( hOpen, "10.5.1.4/downloads/managepoint" , INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0 , 0) ) )
{
CString strMsg;
string strReposeFromServer;
GetLastResponse(strReposeFromServer);
strMsg.Format("Error:%d\nDescription:%s", GetLastError(), strReposeFromServer.c_str());
AfxMessageBox(strMsg, MB_OK);
return false;
}
strStaus.Format("Finding out if this server supoprts Pause & Resume..");
GetDlgItem(IDC_STATIC_STATUSNEW)->SetWindowText(strStaus);
now this works fine up to this point
LPCTSTR lpszVerb = "GET";
LPCTSTR lpszObjectName = "/";
LPCTSTR lpszVersion = NULL;
LPCTSTR lpszReferrer = NULL;
LPCTSTR *lplpszAcceptTypes = NULL;
DWORD dwOpenRequestFlags = INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTP |
INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTPS |
INTERNET_FLAG_KEEP_CONNECTION |
INTERNET_FLAG_NO_AUTH |
INTERNET_FLAG_NO_AUTO_REDIRECT |
INTERNET_FLAG_NO_COOKIES |
INTERNET_FLAG_NO_UI |
INTERNET_FLAG_RELOAD;
DWORD dwOpenRequestContext = 0;
HINTERNET hRequest = HttpOpenRequest(hConnect, lpszVerb, lpszObjectName, lpszVersion,
lpszReferrer, lplpszAcceptTypes,
dwOpenRequestFlags, dwOpenRequestContext);
sendReq = HttpSendRequest(hRequest, NULL, 0, NULL, 0);
HttpSendRequest returns falls however if i change the url to just 10.5.1.4 it returns true however the file that should be downloaded isnt there.
What can i do and what should i do after?
Thanks

HttpSendRequest will set an error that is accessable via GetLastError[^]. You can add something like this to get an error description:
DWORD dwErr = GetLastError();
LPTSTR lpMsgBuf = NULL;
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,NULL,dwErr,MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),(LPTSTR) &lpMsgBuf,0,NULL);
TRACE(_T("ERROR: %s\n"),lpMsgBuf);
LocalFree(lpMsgBuf);
Note that you must place the code immediately following the call to HttpSendRequest().

David,
Actually there is no error it just returns false.
Thanks

Strange.
The only other thing that stands out to me is the line:
LPCTSTR *lplpszAcceptTypes = NULL;
I am not sure if NULL is compliant with the W3C [^]standards. Try changing it to
Accept: text
or
Accept: *
If I am incorrect and NULL is a valid header value then I can only recommend taking a look at the MFC sample code TEAR[^] provided by Microsoft. I have successfully modified and used that sample in projects in the past.
Best Wishes,

Hello!
Its very difficult to debug your code remotely. To better format your code postings in the future I would recommend wrapping the text in the CODE then the PRE tags. Makes it much easier to read when its formatted correctly.
If your goal is to simply download a remote file then perhaps you can use CInternetSession[^] rather than the WinInet classes.
Here is a sample of how to read a remote file over HTTP and write it locally. Much easier!
I pulled this code snippit from an old project. It was inside a CWinThread derived class for multi-threaded downloads.
char httpbuff[512];
CInternetSession Session;
CStdioFile *remotefile = Session.OpenURL(_T("http://www.somewhere.com/somepath/somefile.zip") ,1,INTERNET_FLAG_TRANSFER_BINARY | INTERNET_FLAG_RELOAD);
CFile myfile(_T("\\Path\\To\\Somewhere\\Local"), CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
int iBytes;
while (iBytes = remotefile->Read(httpbuff, 512))
{
myfile.Write(httpbuff, iBytes);
}
If you also need the filesize for a progress bar then you can use CHttpFile::QueryInfo() to get that information. CHttpConnection::OpenRequest() returns CHttpFile.
Best Wishes,
-David Delaune

Does CInternetSession have pause resume capability?
