Function CreateSemaphore can generate a semaphore
As to anythings else I know very little
Can you tell me where better to programme by adopting semaphore
and the way
Thanks

Semaphore is an synchronization element, like event, critical section or mutex - elements used in multithreaded programming. You can look to MSDN for detailed description (see CreateSemaphore function).

Yeah
That is a good idea
and also
note: there are many perfect articles in this site
Maybe that can help us to master "semaphore"
Thank you again!

Hi,
I created a resource-only Dll to store string, dialog, icon and bitmap. With loadstring function i can load a string from this dll, but i don't know how dipslay a dialog from it. here is my code :
UINT CDataResource::GetResourceDialog(int ResourceID)<br />
{<br />
LPCDLGTEMPLATE lpDialogTemplate = NULL;<br />
HGLOBAL hDialogTemplate = NULL;<br />
HINSTANCE hInst = AfxFindResourceHandle(MAKEINTRESOURCE(ResourceID), RT_DIALOG);<br />
HRSRC hResource = ::FindResource(hInst, MAKEINTRESOURCE(ResourceID), RT_DIALOG);<br />
hDialogTemplate = LoadResource(hInst, hResource);<br />
if (hDialogTemplate != NULL)<br />
lpDialogTemplate = (LPCDLGTEMPLATE)LockResource(hDialogTemplate);<br />
else<br />
return 0;<br />
<br />
ASSERT(lpDialogTemplate != NULL);
// HERE I WANT TO DISPLAY MY DIALOG
<br />
UnlockResource(hDialogTemplate);<br />
FreeResource(hDialogTemplate);<br />
<br />
<br />
<br />
<br />
return 1;<br />
}<br />
Thanks in advance

hm... It is about 4 years ago, that I did it...
I had the same ressource IDs in the main App AND in the DLL,
but in different languages.
I guess, you can do it like this:
HINSTANCE hDLL = AfxLoadLibrary("ress.dll");
HINSTANCE hRes = AfxGetRessourceHandle();
AfxSetRessourceHandle(hDLL);
//now do your dialog stuff..
AfxSetRessourceHandle(hRes);
AfxFreeLibrary(hDLL);

hi there 
sorry for this question and dont kill me thanks
(at the moment i work on pocket pc - so there are missing some desktop mfc stuff - but i think its a generally c++ question)
i want to read a file line by line. is it a "good" way to read only once char at time and check for a \n? or is there are more "professional" way to do it?
e.g. this dummy code:
CFile file;
file.Open( L"\\file.txt", CFile::modeRead );
BYTE w[1];
CString s;
while( file.Read( &w, 1 ) != 0 )
{
if( w[ 0 ] == '\n' )
{
MessageBox( NULL, s, NULL, NULL );
s = "";
}
else
{
s.Insert( s.GetLength(), w[0] );
}
}
file.Close();
|
|
|
|
|
<br />
try<br />
{<br />
CStdioFile File("MyFile.txt",CFile::modeRead|CFile::typeText);<br />
<br />
CString strBuf;<br />
bool bNotEOF;<br />
<br />
bNotEOF = File.ReadString(strBuf);
<br />
while ( bNotEOF ) <br />
{<br />
bNotEOF = File.ReadString(strBuf);
}<br />
File.Close();
}<br />
catch(...)<br />
{<br />
::AfxMessageBox("some error");<br />
}<br />
<br />
hope this helps

i found a nearly similar code too ... but there is one problem:
error C2039: 'ReadString' : is not a member of 'CStdioFile'
on pocket pc the readstring method isnt available 
also "getline" + some iostream functions are not available
|

If you look at the implementation of GetLine() of a similar function, you'll notice that it reads from the file character by character until EOF or '\n' is encountered! So what you can do is write your own getline  .
Tip, one of the parameteres should be the length of the buffer you are putting the characters in, this helps avoiding problems.

You could also try using fscanf, which includes a format parameter, and you can specify that the scan reads up to but not including a set of characters. (From memory, check the docs) ...
fscanf (fileptr, "%^['\n']s, &buf);
The format specifier is essentially %s, but in between the % and the s is the "up to but not including this list of chars ... the newline."

Hi
I've write some strings into the registry by using 'WriteProfileString()'.
Like this (in the registry):
MYPROGRAM
|
|-- EMPLOYEE
|
|
Name: Jens
Salary: 3Million Euro

etc
Now i want to delete the entire section ("employee"). How can i achieve this?
Greetings

I have recently had to work with the registry too, and I found that CodeProject has an entire section of articles about the registry. Using the list on the left, follow links through General/System/Registry.
I found that one of the easiest to do "simple" things was from Joseph Newcomer (http://www.codeproject.com/system/registry_class.asp[^]).

Use CWinApp::DelRegTree. It will delete the key and all subkeys. Stay away from the roll-your-own registry solutions. CWinApp's have methods Get/Write for profile data and it can either be the registry or an .INI file.

Hi!
I am creating an application which connects to a ftp server and put a file on the server. When I press the send button it sends the file without problem but it seems to me like my application is freezed until the send operation is done! When I click on something on my program before the send operation is terminated my program just crashes down! This is the code I use:
--------------------
CInternetSession InternetSession;
CFtpConnection *m_pFtpConnection;
try
{
m_pFtpConnection = InternetSession.GetFtpConnection(m_serv, m_user, m_pass, INTERNET_INVALID_PORT_NUMBER, m_passsive);
}
catch ( CInternetException *pEx )
{
TCHAR szError [1024];
if ( pEx -> GetErrorMessage ( szError, 1024 ) )
AfxMessageBox ( szError );
else
AfxMessageBox ( "There was an exception." );
pEx -> Delete ();
m_pFtpConnection = NULL;
}
m_pFtpConnection->PutFile("...............", "............." );
if ( m_pFtpConnection != NULL )
{
m_pFtpConnection->Close ();
delete m_pFtpConnection;
}
---------------------------------------
How can I fix this?
Thank you for your future answers!
Well... I am a beginner ...

This is normal behavior. If you want your application to do other things while the file is being transaferred, but this code in a separate thread. Or you could use CFtpConnection::OpenFile() and CInternetFile::Write() to write the file in chunks, updating your UI in between.
