ucExplorer is an Active-X control wrapper for the IExplorerBrowser object, which allows you to host an Explorer window on your form with options for interaction and configuration. This control is being built in twinBASIC, a 100% compatible successor to VB6, and can be used in tB, VB6, VBA6, VBA7 x87, VBA7 x64, and even Windows Forms in .NET.
You should use the most recent build of twinBASIC to build it yourself. If you intend to use it in VB6, be sure to run as admin when building and enable the 'Register to HKEY_LOCAL_MACHINE' option in project settings.
Update (03 Mar 2024): .twinproj has been updated to use a more recent version of WinDevLib (formerly tbShellLib) due to errors in the package tB did not raise at the time this project was released.
Update (19 Dec 2023): .twinproj updated to reference WinDevLib (formerly tbShellLib) 7.0-- this eliminates package errors that tB did not raise at the time this project was initially released.
5/04 Beta 0.9.7 new crash mitigation attempt
4/30 Beta 0.9.6 crash mitigation proposal from wqweto added.
4/25 Beta 0.9.5 renames the control to ZZucExplorer and changes the GUIDs so it's seen as a whole new control. This is neccessary to avoid caching issues while having multiple builds for debugging the crashing. Also added some more attempts to mitigate that. Added version string in design mode.
4/24 Beta 0.9.4 actually fixes the sizing issue (it seems to have gotten reverted in 0.9.3) and makes another attempt at addressing VBA x64 crash-on-exit.
4/24 Beta 0.9.3 fixes the sizing issue on scaled displays and attempts to address crash-on-close issue in some 64bit Office VBA hosts (but the good news there, it's successfully running and generally working in 64bit Office!). Also fixed the 'doesn't work on XP' message for VB6 running in compatibility mode... had been under the mistaken impression RtlGetVersion didn't lie to you the same way GetVersionEx did.
4/23 afternoon: OCXs updated to address small bug where GetCurrentView did not return all options. OCX test app has been updated to display selection and size the control; tbcontrol-version test app updated to sync code to master. Also confirmed ocx is working (both x86/x64) in tB, next step is to test in VB6 and VBA. Then .NET.
4/23 morning: I've added a test app for the compiled OCX, and compiled OCXs. Note that if you're not building the OCXs yourself, they'll need to be registered, there's currently reg-free sxs, though I will add a manifest for that at some point.
Beta 0.9.2 now available, this makes some final code cleanup and settings adjustments before build testing. Once I've confirmed it works in at least some hosts I'll post compiled OCX builds to Releases as well.
Beta 0.9.1: The control is now configured to build an ocx. The old test form is now in ucExplorerWithTestForm.twinproj. Corrected the version info failure bug making the control think it was on XP.
ucExplorer is now entering alpha testing. The initial feature set is complete, and it's loading to the correct startup path, and the implemented interfaces are being called without raising errors in their default state. The selection changed events are successfully listing files, and the navigation event is successfully reporting new paths. There's a lot of features still to test.
Update: Alpha 0.2 fixes filtering not working when set in design mode, and adds a SetColumns method and a GetCurrentView method for getting the interfaces yourself. Also enables sizing the test form (sizing was working fine, just wasn't enabled).
