Windows Installer Basics: .idt (text representation of database tables)

A ".idt" file is a Windows Installer text format in which a single table's structure and contents is described. This is the first few lines of such a file (for the "Control" table):

Dialog_         Control       Type        X    Y    Width Height Attributes Property Text                 Control_Next  Help
s72             s50           s20         i2   i2   i2    i2     I4         S50      L0                   S50           L50

AdminBrowseDlg  BannerLine    Line        0    44   374    0     1
AdminBrowseDlg  BottomLine    Line        97   234  277    0     1
AdminBrowseDlg  Cancel        PushButton  240  243  56     17    3                   [ButtonText_Cancel]  ComboLabel
AdminBrowseDlg  ComboLabel    Text        25   58   44     10    3                   &Look in:            DirectoryCombo
AdminBrowseDlg  CompanyLogo   Bitmap      330  10   26     26    1048577             BannerGraphic.BMP

Note that the ".idt" file is a tab seperated file and so I touched up the lines above to make the columns more obvious... These are the main features:

You can export and import ".idt" files with "ORCA", you can also do so with these MAKEMSI commands:

The following MAKEMSI shortcuts manipulate ".idt" files:
