VBP builds different configs than IDE by default

[jmm]

I am trying to emulate a bat-file based build process using VBP. I ran across a difference between VBP and the IDE regarding building a project where no configuration is specified (a "default" configuration). The VBP GUI does not seem to allow for a "default" configuration to be built.

E.G.:
When a bat-file containing this IDE command runs:

Msdev c:\build\foo\foo.dsw /MAKE /REBUILD

only the "Win32 Release" configuration is built. But when I build the same project using VBP, VBP tries to build many configurations. The .bld file used to build the project looks like this:

<?xml version='1.0'?>
<project version='5'>
<step action='Make VC6' type='0'>
<Attr type='11'>-1</Attr>
<FileVer type='11'>-1</FileVer>
<Filename>c:\build\foo\foo.dsw</Filename>
<Version>1.2.3</Version>
<VersionSel type='3'>2</VersionSel>
<ignorefail type='11'>-1</ignorefail>
<indent type='3'>2</indent>
<name>VC6 build</name>
</step>
</project>

Can I make VBP build the same *default* configuration as the IDE would?

No. The "default" configuration is a nebulous thing (IIRC, it might be the first configuration physically found in the .dsp file, but I don't believe it's documented anywhere and doubt it's guaranteed to work the same for all versions of Visual Studio). We don't like to rely on such questionable defaults; if you don't explicitly specify the configuration in a Make VC6 action, all configurations will be built.
