The Problem was:
Problem stmt:
Hi Experts,

Contents Assist does not work in eclipse 3.3 CDT.

1.created a c++ project in Eclipse Europa 3.3 for CDT

2.now added a Header file and without compiling , try to use any method
defined in the header file by typing few characters and then ctrl+space

3.we dont get any option unless you save it once which inturn also
compiles the file.

More information:
There is one option in preference page =>c/c++=>check the checkBox
captioned
"follow unindexed files when producing the outline view".
which is to support content assist without compilation but does not work
accurately with europa.

But, if you follow the same steps with "ECLIPSE Genymade" which uses cdt
5.0
version , this option work properly.

So can anybody tell me how to resolve this.

SOLUTION:
As i have done a work around to resolve the problem , and its working in
my case.
In plugin org.eclipse.cdt.core there is a file TranslationUnit.java.
So just cange some line to a function named

public IASTCompletionNode getCompletionNode(IIndex index, int style, int
offset) throws CoreException
{
ICodeReaderFactory codeReaderFactory;
if (index != null && (style & (ITranslationUnit.AST_SKIP_INDEXED_HEADERS |
ITranslationUnit.AST_SKIP_ALL_HEADERS)) != 0) {
ICodeReaderFactory fallbackFactory;
if ((style & ITranslationUnit.AST_SKIP_ALL_HEADERS) != 0) {
fallbackFactory= SavedCodeReaderFactory.getInstance();
==>the above needs to be added and the below need to be commented
//fallbackFactory= NullCodeReaderFactory.getInstance();
}

Hope it should work,let me know incase of any error you face!!!

I suggest to post this to the eclipse.tools.cdt newsgroup.
