I write my report in TeXnicCenter and uses a bib file to create my references.

I have problem with creating the list of references. The error that occurs is:

Warning -- It didnt find a database entry

Adding the bib file in the tex file:

\bibliographystyle{plain}          % uses file "plain.bst"
\bibliography{References4Marsklar} % expects file

Below is how I write in the bib file:

@TECHREPORT{Anomaly detection1,
  author = {J. Ekman and A. Holst.},
  title = {Incremental stream clustering and anomaly detection},
  institution = {SICS Technical Report T2008:01},
  year = {2008},
  number = {},
  owner = {Swedish Institute of Computer Science, Kista, Sweden}

@PHDTHESIS{Bayesian neural network model2,
  author = {Anders Holst},
  title = {The Use of a {Bayesian} Neural Network Model for Classification Tasks},
  school = {Dept.\ of Numerical Analysis and Computing Science. 
    Royal Institute of Technology. Stockholm, Sweden.},
  year = {1997},
  pages = {16--17}

  author = {R. Steinert and D. Gillblad},
  title = {Long-Term Adaptation and Distributed Detection of Local Network Changes},
  journal = {Global Telecommunications Conference (GLOBECOM 2010). Ind.\ 
    Applic.~\& Methods Lab.\ (IAM), Swedish Inst.\ of Comput.\ Sci.\ (SICS), 
    Kista, Sweden},
  year = {2010},
  pages = {1--5},

Can you help me? What is wrong?

Welcome to TeX.SE! You can make the code sections of your question more easily readable by indenting them by four spaces, as I've done in the case above. – Mico Mar 5 '12 at 21:01
Consider reviewing the citation key requirement under BibTeX Intro. – Werner Mar 5 '12 at 21:11

Two comments. First, did you remember to run latex, then bibtex, then latex twice more? Second, you may be encountering problems because the keys of your entries contain whitespace. Do eliminate the whitespace, e.g., by replacing them with dashes, to get Bayesian-neural-network-model2 instead of Bayesian neural network model2. Of course, be sure to adjust the citation commands accordingly.
