I like that. If you want to use dynamic_cast and typeid, you'll better find some good reason and know what you're doing Smile | :)

Hi,

I'm not sure if this is the right place to be asking this question, but if its not I'd be grateful if someone could suggest a good site to go to.

I am using eMbedded Visual C++ and created an application using the AppWizard (exe). It uses shared dlls. My problem is that I am not sure how to add the dlls to my installer package, and which dlls to add. When I was debugging the application on a mobile device it downloaded mfcce300d.dll to the device. I have tried adding this to the installer package but when I try and run the application after installation it says that there is a library or component missing. Any ideas anyone?

Thanks,

Graham

MFCCE300d.dll is the debugging version of the MFCCE300 library (hence the trailing 'd') and is only used when you run the debug version of your app. MFCCE300.dll is the release version and already exists on the device; you don't have to install it yourself.

You can use the dependency walker http://www.dependencywalker.com [^] to determine which DLLs your app uses (even for CE applications).

Google for EZSetup to find a free and open source simple CE installation package. See http://www.pocketpcdn.com/articles/ezsetup.html[^] for an article.

I have a program that search text files in a path that user define.When I click search button it start searching,but the program freeze.So I decide to put this function in a thread.

First:Is that good idea to put it in a thread and does it solve the problem of freezing?I read in MSDN that in worker thread when controlling function exists the thread terminate.My controlling function is recursive function brcause I want to search through directories so is that caused error?

Second:My controling function begins like this:

<br />
UINT FindFile(LPVOID chPath)<br />
{<br />
<br />
  CString strWildcard = (CString&)(chPath);<br />
   <br />
   if (strWildcard == "")<br />
	return 1;<br />
<br />
  CFileFind finder;<br />
<br />
  strWildcard += _T("\\*.*");<br />

It always afetr CFileFind finder line,thrown an unhandled error.Any idea?

Third:How can I access my controls in my dialog inside my controlling funcion?Shoud it be ALWAYS a global function?

Thanks a lot

Probably you're having problems with chPath. I guess you should change (CString & ) to (LPCTSTR), but you didn't post your call to AfxBeginThread.

CString str;
m_editpath.GetWindowText(str);
AfxBeginThread(FindFile,(LPVOID &)str);

Well,I change CString & to LPCSTR.I debug it and "strWildcard" is like this:
{0x003869e8 "îþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþîþ"} ATL::CStringT<char,strtraitmfc<char,atl::chtraitscrt<char>

But there is no difference.the problem happend at CFindFile line.Not at "strWildcard" line.

Your problem is quite interesting. First of all, you're passing a reference to local CString, which is destroyed as soon as you leave the scope. So, depending on timing issues, your FindFile function may get correct string or not.

Easiest (but not elegant) way to solve this problem is to use global variable. You may also allocate a CString on the heap and pass a CString pointer to AfxBeginThread. In this case, FindFile would have to delete the string after it's no longer used.

I'm writing this right here in webpage, so take it with a grain of salt:

// start thread
CString *pStr = new CString;
m_edit.GetWindowText(*pStr);
AfxBeginThread(ThreadFunc, pStr);
// you don't delete pStr here, ThreadFunc will take care of this

...

UINT ThreadFunc(LPVOID p)
{
CString *pStr = (CString *)p;
FindFile(*pStr);
delete pStr;
}

Ohhhhh,thats perfect.It works. Smile | :)

Now I have another questions.How can I figure out the function finish to kill thread?Does thread kill authomaticly after function finish?

I want to update my controls in dialog box during the execution of thread,So I need to access them in my GLOBAL function. Frown | :(

Whats the trick for that?Something like a search of windows.It update list control each time it found the new file.

Yes, thread terminates automatically when controlling function finishes.

What kind of updating it is? Do you just want to add file names to some list control?

Just pass the dialog pointer to thread function instead of string. You'll be able get window text and add items to list as well.

Winsock books for MFC?

the winsock programmes using MFC or related?
thanks in advance

Hello, the codegurus around the world.;)

One time, I also try to find the book saying "WinSock for MFC".
However, I can't find them.

Basically, we write the code of WinSock by C, and MFC is written by C++.
So, it is better to use CAsyncSocket in MFC.
Or, we can create the new Socket class by WinSock.

Some software company maybe uses WinSock and MFC, and we may create more
powerful code than CAsyncSocket. But, we need more skill to do that. Cry | :((

Please, don't send me your email about your questions directly.
Have a nice day!

Best way to intercommunicate between apps

EiSl26-Aug-02 22:44

Hello all,

We've a couple of applications using to perform regression tests. The 'front-end' application which launches and controls all.

Current situation (part of)
- Front-end launches the 'big-app' and uses a fixed delay before continue operation to give 'big-app' the possibility to initialize itself.

Bad part: fixed delay in combination with fast or slow PC.

Prefered situation
- Front-end launches the 'big-app' and continues execution when 'big-app' signals its ready to continue.

My question:
What is the best solution for this signalling event. I need no other info than: "I'm ready... go on".
A named pipe looks a bit overkill too me.

With regards,

EizSl

If the big guy is Windows (not console) app, you should use WaitForInputIdle.

You can use named Win32 event - see CreateEvent and OpenEvent API functions or CEvent MFC class.

You mean using the WM_COPYDATA with use of HWND_BROADCAST in SendMessage ?
