Hope it helps!
I have a blog but I won't link it because some people can't take sarcasm. I might hurt someone's feelings! Check the 'email' button on a post of mine if you want the blog address. If you know the blog address and post something back at CP about whatever I post, you are a hypocrite.

Do you mean thread name for the debugger, the simple way is to remember the name that you have [set for the thread^], you may use [thread local storage^] to store the name but not required.

Actually in processing my DLL_THREAD_ATTACH I only want to process certin threads and I was thinking of Getting the thread name and comparing it to see if its the thread I want to process
However there doesn't seem to bet a GetThreadName API
|
|
|
|
|
Then don't think about debugger SetThreadName, It is available for debugging purpose, if the debugger is not attached then no use you should not use that for final product.
You may use [Thread Local Storage win32 API^] to store the name of the thread at a particular index and retrieve the value.

Problem is in DLL_THREAD_ATTACH
I only want to Process certin threads so...... I want to know the nature of the thread
Tried StackWalk but go to KiAPC.... it was an asyncourous procedure call which lost track of the stack
When going throgh the debugger I get the thread id, the statement after CreateThread or in this case since the orignal app is in C is _beginThreadx it would be nice if some how using the thread id I could some how tell the DLL_THREAD_ATTACH message the nature of the thread
Thankx

Hi all,
What is the counter part of the FtpCommand function for http? I need this inorder to find out if a certain http site supports pause and resume
BOOL bRet = ::FtpCommand(hConnect,FALSE,FTP_TRANSFER_TYPE_ASCII, "REST 0",0,&,hResponse);
This is the line
Thanks,
Jj

Hello again monsieur_jj,
You can use the code I posted yesterday[^] to pause/resume your download. You can easily implement it yourself. First you need to acquire some knowledge about HTTP. The ability to pause/resume a file download is actually taking an advantage of a function of the HTTP 1.1 RFC[^] over at the world wide web consortium[^].
If you take a look at section 14[^] and scroll down to 14.16 Content-Range you will see the description of how to obtain a range of bytes from the requested file. For example:
1.) When the HTTP download begins you should store the content length.
DWORD dwFileSize;
pSession->QueryInfo(HTTP_QUERY_CONTENT_LENGTH | HTTP_QUERY_FLAG_NUMBER,dwFileSize);
2.) Open the URL with the sample code I provided in my last post and begin writing the bytes.
3.) If the user pauses the download close the CInternetSession in the middle of writing to the file. Save the number of bytes written to a variable for later use.
4.) User resumes the download and you compare content-length with amount you previously wrote to disk. Re-open the file on disk and reopen the CInternetSession and URL.
But this time we add the Range header! For example:
"Range: bytes=1024-2048"
"Range: bytes=1024-"
"Range: bytes=-1024"
Any library which allows to add HTTP headers can be made to pause/resume HTTP downloads by simply adding the correct headers. Hope this helps!
Best Wishes,

Hello David,
May i ask you one question? actually i am working on project suggestion list and for every hit a request is send to server and than responce occur. this is done using http connection.now we are using thread for sending the request because we do not want that user will wait for responce while typing and one more condition i use is that i am taking an Id for requset and responce. when they are equal than only suggestion list is display.
It is working fine but after typing some lines a crash appear. IT is because of thread that is created everytime. I dont find any clue why is it so. bcause it take time to destroy a thread but on every hit thread is created.
Can yo please suggest me what is wrong .I am regularly checking your reply
Thanks

Hello Shilpi,
It is very difficult to say what is wrong without looking at the code. To eliminate the possibility of deadlocks and race conditions I always recommend using PostThreadMessage/PostMessage for communication between application dialogs and threads.
If you are creating a very large number of threads you may want to research STACK_SIZE_PARAM_IS_A_RESERVATION. When you use CreateThread it defaults to reserving 1 MB of stack space each thread. This can limit the amount of threads available to your application. I always reduce the stack size to 512 kilobytes for low-duty worker threads. For example:
CWinThread *pTmpThread = NULL;
...
...
if (NULL != pTmpThread)
{
ASSERT_VALID(pTmpThread);
if (!pTmpThread->CreateThread(CREATE_SUSPENDED | STACK_SIZE_PARAM_IS_A_RESERVATION ,524288,NULL))
{
delete pTmpThread;
*pOldThread=NULL;
return;
}
pTmpThread->m_bAutoDelete = TRUE;
VERIFY(pTmpThread->SetThreadPriority(THREAD_PRIORITY_NORMAL));
pTmpThread->ResumeThread();
PostThreadMessage(pTmpThread->m_nThreadID,WM_THREAD_START,0,0);
}
Once again it is very difficult to say what is the problem without having a look at your code. If you continue to have this same problem I would suggest creating a new post here on the C++ forum and maybe add some source code.
Best Wishes,
-David Delaune

Hi David,
Thanks for reply
I got the issue that was my mistake actually i am not tackle one condition and after fixing that bug it is working fine.
I am not using CWinThread. I am using one simple function as a thread.It is another way to create a thread.
Thanks Soo much

Hi David,
Can you give me an example on how those headers are used?
Thanks,
Jj
|
|
|
|

You simply need to pass the header text in OpenURL(). Have a look at the function GetHttpFile() in this example[^].

Are you wanting to close another dialog from your dialog? You need to give us a little more information (and relevant code to support it).
