    no :(

    new ASP (JASON_UTIL.ASP) code - SELECT is ok:
    Function QueryToJSON(dbc, sql)
    Dim rs, jsa
    Set dbc = Server.CreateObject("adodb.connection")
    dbc.CursorLocation = 3 "provider=SQLOLEDB;server=(local);Database=db","sa","pwd"
    Set jsa = jsArray()
    If mid(sql,1,6) = "update" then
    Set rs = dbc.Execute(sql)
    While Not (rs.EOF Or rs.BOF)
    Set jsa(Null) = jsObject()
    For Each col In rs.Fields
    jsa(Null)(col.Name) = col.Value
    End If
    Set QueryToJSON = jsa
    End Function
    browser (ok): table set J3=1 Where Numero=1
    the table is updated

    B4a (no error), but not updated:
    SQL = "query=update wCadBateria set J3=1 Where Numero=1"
    HttpUtils.PostString("UPDATE", ServerUrl, SQL)

    If Job = "UPDATE" Then
    UpDate = True
    End If

    UPDATE ok


    The error is in another string with blanks

    " ...where n=1 and F = 'Fase 1' "

    i´ll change the " " for "%20".

    i try to use this code (from post #1), but after I added the two files (HttpUtils and HttpUtilsService) to my project and tried to compile it I received the following error:
    Compiling code. 0.04
    Compiling layouts code. 0.00
    Generating R file. 0.22
    Compiling generated Java code. Error
    B4A line: 60
    HttpUtilsService.PostBytes = Data
    javac 1.6.0_27
    src\natura2000\mmare\ incompatible types
    found :
    required: byte[]
    mostCurrent._httputilsservice._postbytes = mostCurrent._data;
    1 error

    What am I doing wrong?

    Connection MS SQL

    It is possible to make a connection from Android device to a Microsoft SQL server without using ASP, but with a library ?

    Thank you

    I'm afraid that it is not possible.

    This thread is not about mssql library. Please start a new thread for this question.

    If you like you can post the error you got when trying this example.

    This thread is about using an ASP .Net web service to connect to a MS SQL database. I don't think that it is related to your question.

    Well done

    After appropriate modifications, the example code can run very well.
    Look forward to more and better.

    I have web service up and running on MSSQL database.
    Tested in web browser and its working

    Problem is with Android app since it always returns

    HttpUtils.IsSuccess(ServerUrl) = false

    and logcat contains this
    What should I do ?
  19. Erel

    Erel Administrator Staff Member Licensed User

    localhost points to the device not to the computer. Are you using an emulator or a real device?
  20. jalle007

    jalle007 Active Member Licensed User

    I tried both.
    The device is on the same netowrk as localhost (PC)
    I tried entering IP on my device and yes it opens my IIS homepage.

    but whenever i try to call eg:
    from code , httputils response with NoSuccess (because it cant see localhost)

    I would really like to test the app working with localhost rather then uploafing the page to remote server...
