Show New Form And Lock Other One?

Jul 24, 2009

I have my main form then a progress bar form that is shown when the program is running. I simply want to keep the progress bar form on top of the other form and make the other form so it can't be changed.

I've tried form2.showdialog, but that stops the code in the main form from running so it's no good.

form2.show(me) just keeps form2 ontop of form1

me.topmost in form2 does the same as the last thing

setting the form1.enabled = false isn't something I want to do since you can't even move the form when it's like that

So really I'm at a complete loss here

also how can I get the progress to start in the center of form1? There is a setting in the form properties but is doesn't seem to work.

The form is full screen, but I can shift the location. I do have a dual screen system. The application goes full screen on the left most screen. This does this inside the development environment and using the EXE. What am I missing? I thought Locked is suppose to prevent the form from moving.

Lock Records On SQL?

Sep 25, 2009

I have a form and its filled from a VIEW of two tables on SQL server. When its opened i dont want other users opening that customers details from either table.I know SQL itself prevents writes if its opened but i want to stop people opening the record in the first place.[code]...

I then tried writing these values to the db on the form loading but it doesent work - it just sends back NULLs. I tried the same code in the on load event into a button and it works fine there. So im thinking i should do this as a Trigger on SQL itself, but im unsure how i could get the users computername or Windows Login name, or even username from the front end im building.
