I've been at this on/off for about a week now. I put it to the side & move onto other things and now I'm back to it.
I have a datagridview (dgvScheduleInfo). In its properties I have the "ReadOnly" set to true. I have 6 columns (0-5). The last column ("Notes") I want to make editable if someone clicks on a "Edit Notes" button. Sounds simple enough.
I've used the following code to no avail:
dgvScheduleInfo.Columns(5).ReadOnly = False
dgvScheduleInfo.Columns("Notes").ReadOnly = False
The code above errors out with a "Object reference not set to an instance of an object." even though when I step through the code it shows "Notes" as the name.
I've tried hard-coding a value for testing purposes:
Hello: I'm working on a large database project that I currently have in VBA/Access 2007 and intend to put into VB.Net/Access 2007 as I think it might be a better idea but I'm not sure. This program is for a large law case where I will be required to deploy it by sending it out on disks to various other firms across the country. I'm a bit rusty with this so I want to know the best way to handle the solution. If all these other firms don't have Access, what other type of database should I use? What is the best practice for deployment?
Your users do not need to have Access installed; you'll need the JET/MDAC libraries, that's what VB needs to read/write Access-databases. If you need some of the functionality from Access, you could distribute the Access Runtime[^].
I'd recommend against using Access, unless it's a single-user database. Sql Server (Express) would be a more reliable way.
Hello I'm a newbie at programming and I've taken on my biggest challenge and that is to communicate to my iPhone through the USB serial...I understand that the iPhone communicate via usbmuxd. I've downloaded the software and converted it to vb, but I don't know where to start as far as opening up the ports and getting the coding right. Any help would be appreciated.
