Adding Controls To The Visual Studio Toolbox
The controls are automatically added to the Visual Studio Toolbox during installation of SftTree/OCX and are located in the toolbox group "Softel vdm, Inc.". The controls can also be added to the toolbox "manually" using the following simple procedure.
Adding SftTree/OCX
Adding The SftHelperComponent Component
Adding SftTree/OCX To The Visual Studio Toolbox
For Visual Studio 2019, 2022 and 2026 the controls are automatically added to the Visual Studio Toolbox in the toolbox group named "Softel vdm, Inc." and this section can be skipped. Otherwise, the SftTree/OCX control must be added to the toolbox before it can be used in a project.
Open a form in your project in design view. Right-click anywhere on the Toolbox and select "Add Tab" from the popup menu.
This creates a new tab for the control to be added.
To complete the new tab, enter a suitable tab label. In this example, we enter "Softel vdm, Inc." and press Return.
Once the tab has been added, we are ready to add controls to it.
Right-click on the area below the tab heading and select "Choose Items..." (or Add/Remove Items... in older Visual Studio versions) from the popup menu.
This will present the Choose Toolbox Items dialog, which is used to locate the ActiveX control you want to add.
Finally, click OK and the control now appears in your Toolbox.
Adding The SftHelperComponent Component
For Visual Studio 2019, 2022 and 2026 the controls are automatically added to the Visual Studio Toolbox in the toolbox group named "Softel vdm, Inc." and this section can be skipped. Otherwise, the SftTree/OCX control must be added to the toolbox before it can be used in a project.
Open a form in your project in design view.
In the toolbox, locate the group "Softel vdm, Inc.", created when the SftTree/OCX control was added to the toolbox (see above).
Right-click on the area below the tab heading and select "Choose Items..." (or Add/Remove Items... in older Visual Studio versions) from the popup menu.
This will present the Choose Toolbox Items dialog, which is used to locate the .NET component you want to add.
The SftHelperComponent is located at C:\Program Files\Common Files\Softelvdm\Softelvdm.Controls or C:\Program Files (x86)\Common Files\Softelvdm\Softelvdm.Controls on 64-bit Windows versions.
Add the assembly Softelvdm.OCXHelperV2.dll.
Locate the assembly and click Open to accept.
This will return you to the Choose Toolbox Items dialog which now shows the newly added assembly.
Finally, click OK and the control now appears in your Toolbox.
