Leaker! ;)

Service engineer working in horticulture... is that code for clearing weeds from the cannabis crop? :doh: Not sure of the details of your work, but lets say there are several "locations" you maintain. Does the company you work for have any type of software to track which "locations" have been serviced? Even if the company already has this tool, I suggest writing a Django app (as you are already learning Python) which you could use to track your servicing activities. Work in phases. First track where you have been, then expand the tool to include predictive behavior (i.e. have not been to location "X" in 5 weeks, time for preventative maintenance). You could even have the app create reports on which "locations" are the most problematic - if you add info about what machinery / tools the sites have, you could do comparisons on problematic vs. tool type, etc. As you already have knowledge of the horticulture service industry, you are in a great position to create a software tool like this - don't be discouraged if there already is an app that does this... New apps (though sometimes not better) are always supplanting older ones. The trick is to make yours better.

Dim cb As CheckBox = CType(Me.Controls.Find("A1", True)(0), CheckBox) cb.Checked = True

I had a similar problem (&Cancel button randomly gains focus) with an app I developed (VB2005), but I was able to code an "Are you sure?" work around. This issue only seems to occur on one desktop. It has a unique piece of hardware which I blame: a 'mini' keyboard with a PS/2 connector as opposed to a standard size USB keyboard.

I had this one about 2 years ago... I had put some code inside my "form1" and found that the code ran, but the form seemed to never appear. If you put a DoEvents after the show, then a Msgbox, you'll see what's happening... Your form is actually loading, but the program is exiting after the form.show method. If you want to load the form and not exit "Main" until you close the form try using the ShowDialog method of the form instead of the Show method. I think that's what you are looking for.
