Vista:VB6 Checkboxes and Radio buttons dont show that they get focus when tabbed onto when using MS Windows common controls 6

Application Compatibility for Windows Vista

jads


When running a VB6 program on Vista that has checkboxes and/or radio buttons,, and you tab between the fields, you cannot see which of the fields has focus. In XP it showed focus by putting a rectangle around the checkbox and its caption, which does not occur on Vista.

The program is using a manifest embedded as a resource to use xp/vista themes.

You can replicate by placing some checkboxes and a text box on a form and compile as a standard exe. run on XP and you can see which field has focus. Run on Vista and you can only see when the textbox gets focus.

For me behaviour is the same under both OSs. I'm getting no indication of the current checkbox under Vista and XP when XP display style is set with a manifest file. When a manifest file is not present both OSs do show the current checkbox with a rectangluar outline.

Any idea why the checkbox is not being indicated as the current one The form I am using is pretty basic:

form content is

Searching for any possible info on this turned up zippo. My suggestion that if you continue to have issues with VB6 and this to contact VB support.

Yep. VB6 Checkboxes and Radio buttons dont show that they get focus when tabbed onto when using MS Windows common controls 6

but the upside is that in Vista if you have Command buttons on a Frame Control you no longer have to put them within a Picture to avoid the black borders, text in the caption of a Frame Control will also display as intended. Option buttons on a Frame Control also appear to display as intended without placing them into a Picture Control.

Hav'nt experimented myself but may be you could try changing the backcolor of a Control in its Get/Lost Focus events to indicate it is current.

Yes have tried that and it does work, bit of a pain though when there are many checkboxes and radio buttons.

Also have to run on XP as well as Vista, so cannot remove picture boxes as containers on frames

Ronny S.

I recently came over the same problem. If you want to have an application that work correct on XP and Vista you have 2 possibilities.

1. Put a Picturebox inside of every Frame that contains radio-buttons.

2. Replace the Frame control with another that does everything ok

If you want your app to display the focus correct (I think you have the same problem with the command-buttons) there is 1 workaround and 1 solution

1. To workaraound you have to turn on the accelerator-keys in windows system settings.

2. you have to subclass every form to capture the keyboard input and then pass a message to your form in case the Alt- or Tab-Keys are pressed. Windows-XP and Vista do only show the focus and accelerator-keys when you press a key.

There are freeware-controls that you can use: http://www.timosoft-software.de

Try the Button-Controls. I think there are code-samples which also include the subclassing to display focus.

Currently I am working on a project to automate the steps of replacing the VB.Frame control with the Framecontrol from timosoft. The project isn't finished jet, because it's harder than I thought....

I hope this helps...
