Hey Raj,
As a side note on this, I wrote a little app that goes over the heat
generated output and uses the lower-case, variablized value of the Source
attribute of the File elment. I then take that element and hash to generate
a, more then likely, unique file ID. The process looks something like this.
*Heat Output:*
<Directory Id="Website" Name="Website">
<Component Id="AddCategory.aspx" Guid="PUT-GUID-HERE">
<File Id="AddCategory.aspx" Name="AddCategory.aspx" KeyPath="yes"
Source="D
:\Development\PIDashboard\_OUTPUT_\1.0.0\Debug\App\Website\AddCategory.aspx"
/>
</Component>
*Re-org:*
<Directory Id="Website" Name="Website">
<Component Id="AddCategory.aspx" Guid="PUT-GUID-HERE">
<File Id="AddCategory.aspx" Name="AddCategory.aspx" KeyPath="yes"
Source="$(var.RootPath)\AddCategory.aspx" />
</Component>
*Hash:*
$(var.Root)\Website\AddCategory.aspx = $(var.root)\website\addcategory.aspx
protected string GetHashString(string s)
{
StringBuilder sb = new StringBuilder();
UTF8Encoding enc = new UTF8Encoding();
HashAlgorithm alg = HashAlgorithm.Create("MD5");
byte[] hash = alg.ComputeHash(enc.GetBytes(s));
foreach (byte x in hash)
{
sb.AppendFormat("{0:X2}", x);
}
return sb.ToString();
}
Output = CAE00571B0687E8E2CBD42D8F2D711F6
*Final Result:*
<Directory Id="D_903BF5C74F67E118C77BB96BA956A5CE" Name="Website">
<Component Id="CK_102FD739712DE86F5AC38CE8AA5E567A"
Guid="{B73B5A74-79AA-4E73-B23C-9F54E42FF494}">
<File Id="F_CAE00571B0687E8E2CBD42D8F2D711F6" Name="
AddCategory.aspx" KeyPath="yes" Source="$(var.RootPath)\AddCategory.aspx" />
</Component>
The major problem with the app is that it regenerates GUIDs each time it
runs. This is required in the build environment this is executed in at the
moment. The hope is to look up GUIDs from some for of data store to keep
with the best practices of components in Windows Installer.
Besides that, this should let you keep same named files in different
directories from colliding. It should also ensure that the file is unique
via its location if you want to reference later inside of the installer.

Hope that helps,
