Two differnent selections (plus) when looking at forms properties
If you open the properties dialogue, you can click on several different selection including the different sections of the form. However, you can also click on the box in the upper left corner of the form which gives properties of the form itself, or click on the frame of the form, which shows the properties/relationships of the form/subform.
You can format virtually anything in that manner by drilling down to it. (Anything that is, except it seems a tab control, which seems to have limitiations on [what] you can change - though even there you can change some things.
Again, why don't you just edit the subform directly?
Good grief Blindman - this is front end development. You don't just take 5 minutes to change something manually for each form - you spend two days writing a code routine to do it for you.
Do you mean the fonts and what have you of the controls on the subform? If yes - select the sub form in design view, Ctrl + A (select all) and enter the font names and sizes via the formatting tool bar.
BTW - easy way to get everything (that you subsequently create) to look uniform is to create a form and a report, set up all your properties (including properties for each control) save and then click Tools -> Options -> Forms\ Reports and enter the names of your newly created form and report into the relevent template entries.
