i have problem auto completion in visual studio 2013 express .what i can do please ?

Microsoft recently released Visual Studio Community, which comes with an immensely improved Intellisense as compared to the Express’ version.

Its totally free as long as you meet either of these two requirements:

  1. An unlimited number of users within an organization can use Visual Studio Community for the following scenarios: in a classroom learning environment, for academic research, or for contributing to open source projects.

  2. For all other usage scenarios: In non-enterprise organizations, up to 5 users can use Visual Studio Community. In enterprise organizations (meaning those with >250 PCs or > $1MM in annual revenue), no use is permitted beyond the open source, academic research, and classroom learning environment scenarios described above.

Here is a download link.
