I have event handlers to update datatables when input is changed on a form. When the form is loaded some objects are programatically changed depending on data in the datatables.pecifically, default values are populated using code. These changes cause events to fire causing data (mostly null when the first event fires) to be saved causing errors.

How to get the file path of the Temp directory (% temp%)? I use Visual Basic 2010
View 1 RepliesAm trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.

I need to disable events while the combobox is being populated. How do I do this?

I hava a form app, that runs hidden, with just a notify icon, the goal is control worker schedule and alert them for some things they have to do.My problem is,when i open a form (with TopMost = True), it works if the user is admin of the machine or domain admin, if the user is "regular" user, the form just don't open or shown to the screen.I believe that it has got something to do with write permissions in the app folder. I have a contextmenu that works great, even restoring the hidden main form, it just doesn't show/open the other form, without any error.Shouldn't .net use the user $temp folder to write something? If not what's the best way for the app use the EnvironmentVariable("temp")?
