Description of article:
The purpose of this article is to present a method whereby both static and non-static class member functions, as well as non-member functions can be used as callback functions. Type-safety is important in this implementation, and some features are left out in order to retain this.

You can't because static member functions and standard member functions don't have the same prototype: for the latter, an implicit this parameter is passed.
The way to solve this problem is that in general, most callback functions allow you to pass some data (in general a pointer). Pass the pointer to your class instance (this) along the address of the static function that will be used for callback. In the callback function, you can then cast back the pointer to your class and call a member function from it (it should be public).

I read already those threads...
The problem is i am not able to read a text file...
how to delimit the text file..
|

Why are you using OpenText() instead of Open()? I use the latter with text files, but OpenText() will work also.
In any case, what error are you receiving?

I thought I already did. Use:
books.Open("c:\\book1.txt",
COleVariant(0L),
vtFalse,
COleVariant(6L),
vtOptional,
vtOptional,
vtTrue,
vtOptional,
vtDelim,
vtOptional,
vtOptional,
vtOptional,
vtFalse,
vtOptional,
vtOptional); If you still need to use OpenText(), try:
books.OpenText("c:\\book1.txt",
COleVariant(1L),
COleVariant(1L),
COleVariant(1L),
-4142,
vtFalse,
vtFalse,
vtFalse,
vtFalse,
vtTrue,
vtFalse,
vtOptional,
vtOptional,
vtOptional,
vtOptional,
vtOptional,
vtOptional,
vtOptional);

That's what the tenth argument to OpenText() is for.

You should not open a .txt file like this. Because there is no need for any automation in this.
You use this...
CStdioFile myFile;
CFileException fileException;
myFile.Open( "F:\\test.txt", CFile::modeCreate | CFile::modeReadWrite|CFile::modeNoTruncate, &fileException );
myFile.Write(const void* lpBuf, UINT nCount);
myFile.close();
Thanks and Regards.

Hi, I need to create a Setup.exe of mi app. I have a problem.
What I have done is that:
Build->Configuration->Select Release
Compile, build
There was an error:
fatal error C1083: Cannot open precompiled header file: 'Release/TMB.pch': No such file or directory
I changed the settings and selected
Precompiled Headers->Not using precompiled headers
But now it says:
error LNK2001: unresolved external symbol _dbdead
error LNK2001: unresolved external symbol ...
error LNK2001: unresolved external symbol ...
error LNK2001: unresolved external symbol ...
about 30 times.
What should I do?
Time to come clean...

Hi,
hope this might help
While programming in VC++ using dblibrary for c I too got some Unresolved externals error.
I don't know much about your IDE,but here's what I did in VC++
1. clean your solution: Build > Clean Solution
2. found out the name of the required lib file
3. Project > settings> links tab , added the .lib file name to list of Object/Library modules

How to store and retrieve the properties of an object using Serialize?
|
|
|
|
|
Serialization is a topic (i.e. your question is a bit too broad): Google is your best friend.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.
-- Alfonso the Wise, 13th Century King of Castile.

CObject ... DECLARE_SERIAL .... Serialize ... IsStoring ... are the clues
