PowerBuilder .NET Web Forms use Internet Explorer Web Controls to display correctly and to provide functionality for the Tab, TreeView, and Toolbar controls.
You can download IE Web Controls from the Microsoft Web site. The download comes with a Readme file that provides instructions for installing the controls.
After you install the IE Web Controls by running the build.bat file included in the download, you must copy the controls to a webctrl_client\1_0 directory under the IIS root.
To copy the IE Web Controls:
Open a DOS command box.
Change directories to the directory where you installed the IE Web Controls.
Type the following line at the command prompt, modifying the server IIS root directory if you do not use the default c:\Inetpub\wwwroot directory:
xcopy /s /i .\build\Runtime c:\Inetpub\wwwroot\webctrl_client\1_0 /y
Press Enter.
This creates the following directory structure under the root: \webctrl_client\1_0 [images] [treeimages]
The \webctrl_client\1_0 directory should contain the following files: MultiPage.htc, TabStrip.htc, toolbar.htc, treeview.htc, webservice.htc, and webserviced.htc
