Custom auxiliary files folder

[ioanvlad]

Besides the installation folder for my executables, I need to create a folder with auxiliary files, in a user-selected location (if user selects a custom install), or in C:\My Data if user selects a default install. I have a custom dialog allowing the user to select the data folder and store the location in a DATAFLD property, but somehow the value being selected by user is not transmitted, so the directory always is C:\DataFolder. What am I doing wrong? Below I describe how I do things. Many respectful thanks.

I have inside my Package element:

<Property Id="DATAFLD" Value="[WindowsVolume]DataFolder" />

<Directory Id="DataFolder"> <Directory Id="DataFolder2" Name="My Dir2 Name" /> </Directory>

and various component files specifying one of the two folders as their Directory.

To provide the dialog making this choice, I create a dialog with:

<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs">
<Fragment>
<UI>
<Dialog Id="InstallDirDlgData" Width="370" Height="270" Title="!(loc.InstallDirDlg_Title)">
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)" />
<Control Id="Back" Type="PushButton" X="180" Y="243" Width="56" Height="17" Text="!(loc.WixUIBack)" />
<Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56" Height="17" Cancel="yes" Text="!(loc.WixUICancel)">
<Publish Event="SpawnDialog" Value="CancelDlg" />
</Control>

<Control Id="Description" Type="Text" X="25" Y="23" Width="280" Height="15" Transparent="yes" NoPrefix="yes" Text="!(loc.InstallDirDlgDescription)" />
<Control Id="Title" Type="Text" X="15" Y="6" Width="200" Height="15" Transparent="yes" NoPrefix="yes" Text="Data Folder" />
<Control Id="BannerBitmap" Type="Bitmap" X="0" Y="0" Width="370" Height="44" TabSkip="no" Text="!(loc.InstallDirDlgBannerBitmap)" />
<Control Id="BannerLine" Type="Line" X="0" Y="44" Width="370" Height="0" />
<Control Id="BottomLine" Type="Line" X="0" Y="234" Width="370" Height="0" />

<Control Id="FolderLabel" Type="Text" X="20" Y="60" Width="290" Height="30" NoPrefix="yes" Text="Set as Data folder:" />
<Control Id="Folder" Type="PathEdit" X="20" Y="100" Width="320" Height="18" Property="DATAFLD" Indirect="yes" />
<Control Id="ChangeFolder" Type="PushButton" X="20" Y="120" Width="56" Height="17" Text="!(loc.InstallDirDlgChange)" />
</Dialog>
</UI>
</Fragment>
</Wix>

and I publish it with:

<Publish Dialog="InstallDirDlgData" Control="Back" Event="NewDialog" Value="InstallDirDlg" />
<Publish Dialog="InstallDirDlgData" Control="Next" Event="SetTargetPath" Value="[DATAFLD]" Order="1" />
<Publish Dialog="InstallDirDlgData" Control="Next" Event="DoAction" Value="WixUIValidatePath_$(sys.BUILDARCHSHORT)" Order="2" Condition="NOT WIXUI_DONTVALIDATEPATH" />
<Publish Dialog="InstallDirDlgData" Control="Next" Event="SpawnDialog" Value="InvalidDirDlg" Order="3" Condition="NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID&lt;&gt;&quot;1&quot;" />
<Publish Dialog="InstallDirDlgData" Control="Next" Event="NewDialog" Value="InstallDirDlgProj" Order="4" Condition="WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID=&quot;1&quot;" />
<Publish Dialog="InstallDirDlgData" Control="ChangeFolder" Property="_BrowseProperty" Value="[DATAFLD]" Order="1" />
<Publish Dialog="InstallDirDlgData" Control="ChangeFolder" Event="SpawnDialog" Value="BrowseDlg" Order="2" />
