1. Please use [code]code here...[/code] tags when posting code.
2. Don't waste your time and switch to B4XPages.
2. Post the error message.

    'These variables can only be accessed from this module.

    Private lblKode As Label
    Private edtKode As EditText
    Private lblProdName As Label
    Private edtProdName As EditText
    Private lvDtMaster As ListView
End Sub

Sub edtKode_EnterPressed
    mdlconn.CSR1= mdlConn.SQL1.ExecQuery("select * from MasterData where SKU = '" & edtKode.Text & "'")
    If mdlConn.CSR1.RowCount > 0 Then
        'Csr1.Position = 0
        ToastMessageShow("Found",True)
        edtProdName.Text = Csr1.GetString("Name")

[DonManfred]

mdlConn.CSR1=mdlConn.SQL1.ExecQuery("select * from myTabel where PartCode = '" & edtCdItem.Text & "'")

where is the full error?

 

[jamir]

where is the full error?

this code "mdlConn.CSR1=mdlConn.SQL1.ExecQuery("select * from myTabel where PartCode = '" & edtCdItem.Text & "'")" is running very well

the full error when program is running, when Press ENTER after type the SKU textbox
Error message in application when i add the sintaks "edtProdName.Text = Csr1.GetString("Name")" in Sub edtKode_EnterPressed
when i delete that syntax the application running very well

in this case, i want to display at NAME Textbox after i type the SKU textbox, with even EnterPressed

sorry my English so bad

thx Manfred for ur attention

 

[jamir]

typo : even -> event
in this case, i want to display at NAME Textbox after i type the SKU textbox, with event EnterPressed

In one place you refer to the cursor: mdlConn.CSR1 and in another place, you refer to it: CSR1 without a prefix. It should be without the prefix

 

[jamir]

edtProdName.Text = mdlconn.CSR1.GetString("ProdName")
I've tried that syntax before but the result is still error and then i try edtProdName.Text = CSR1.GetString("ProdName"), its the same error when the application running

btw thx Mahares, thank for ur share and coming... any solution again ?

 

[Mahares]

any solution again ?

Is there any chance you put a small project together to reproduce the problem. It does not seem too complicated to solve your problem. Someone, will probably get back to you. You have a better chance of getting a better answer.
Even if you do not get an answer you will get advice on: Using a full parameterized query, using resultset instead of cursor and closing the cursor when finished.
