Hello,
Hope that someone can help me please?
I am using MSO8104A scope for my measurement and using vb.net as visual basic language. I have been stuck to one problem for a long time. The problem might not be very big for though.
I am using save waveform comment to save data from the oscilloscope. Once I save one group of data in one file I want the send group of data to be saved in the same file rather than creating another file when I am running a loop. Please can anyone suggest me which comment or code I can use to append the data in one file other than having many files?
Please kindly help!
Thanks

Open the file for appending. All explained in the documentation.

If it's all just "string" data, then you can just use File.AppenAllText.
If it's in another "format", then you need a custom solution that only the vendor's documentation can answer.

I like to use regions to collapse code but in VS 2019 the regions are not collapsible and are not marked as outline elements. Any idea if these are configurable?

Regions are working for me in 2019. The +/- button to expand/collapse is on the left border of the window just like it's always been.
It may be turned off for you. Type "region" into the new search box at the top of the VS window and the first item listed should be "Show outlining for comments and preprocessor regions". Make sure that's turned on.

Damn this was supposed to be in the Visual Studio forum.

I already said how to find it.
The new Search box in the center of the VS window just under the title bar. Type "region" into it and the first item should take you straight there.
But it that doesn't get you there, Tools -> Options -> Text Editor -> C# -> Advanced. The option is under "Outlining", the forth paragraph down.

You look at it.

OK, so what's stopping you from just getting the username on the login form from the database when you authenticate the user and then passing that data to the main form of your application? This is basic stuff, passing data between classes, and Forms are just classes.

how i can import from a text file also from database to one datagridview
|
|
|
|
|
That's not an import, but simply reading and displaying data. There are multiple articles and tutorials on loading data in a grid.

i need help to get my code work for one datagridview.

I'm having trouble understanding your question; do you want to load from "both" sources into the same gridview and display them as one?

yes exactly from both to one datagridview
|
|
|
|
|
If you execute one after the other, both would add rows to the datagridview. There is no .Clear() visible in your code, so one would assume it to be appended.

before i remember i do it like that but now many time trying without a solution
|

Dim ouvrir As New OpenFileDialog
If ouvrir.ShowDialog = DialogResult.OK Then
Dim aline() As String
Dim sr As New StreamReader(ouvrir.FileName)
While Not sr.EndOfStream
Dim ligne As String = sr.ReadLine
aline = ligne.Split(CChar(vbTab))
DataGridView1.Rows.Add(aline)
End While
cn.Open()
Dim cmd As New SqlCommand("select * from F_COMPTET", cn)
Using da As SqlDataReader = cmd.ExecuteReader
While da.Read
DataGridView1.Rows.Add(da("CT_Num"))
End While
End Using
There's only "adding" done to the rows, so both should be visible if you execute this.
