I have a Panel with many buttons inside it which is under Panel.Controls

each button inside the panel has a One Dimensional Array in their Tags which contains these data.

(0) = State / Flag
(1) = Button ID Coordination
(2) = Button Current Flag in Addressing / Clicking
(3) = Stored Actual Position Value

My Goal here is How i can find the index of the correct button which contain the flag i wanted to find in their tags.

i can think of solution is using Array.FindIndex via converting first the Panel.Controls collections into a Button() / Array of buttons

then Find the tag(2) which valued 1 so i can also get the Index of that button and retrieve the Actual Position value

need help ASAP reply PLEASE !!!

make a structure rather than the array; im not sure if this is what you need.
NOTE: only 1 button is added to panel (Panel1, Button2)

example:

Private SelectedIndex As Integer

    Public Structure myTag
        Public Property stateFl As Integer
        Public Property buttonId As Integer
        Public Property buttonAddressing As Integer
        Public Property positionValue As Integer
    End Structure

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim currentTag As New myTag
        With currentTag ' feed value here
            .stateFl = 0
            .buttonId = 1
            .buttonAddressing = 2
            .positionValue = 3
        End With

        Button2.Tag = currentTag

        Dim retrievedTag As myTag = Button2.Tag
        With retrievedTag
            MsgBox(String.Format("{0} {1} {2} {3}", .stateFl, .buttonId, .buttonAddressing, .positionValue))
        End With
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        SelectedIndex = Panel1.Controls.GetChildIndex(Button2) ' palitan mo to if runtime generated ang mga buttons, also need mo mag add ng handler on each button created (IF RUNTIME GENERATED)
        MsgBox(SelectedIndex)
    End Sub

what is your table structure?

but try this, i could not help that much without the table structure.
select the day as column. if days are incomplete, create a temporary table to store all days in a month then update each column.

 

[karloy]

guys patulong naman kung pano gawin to.

thanks

I made this thread for all programmers starting their adventure in VB.NET.

Please post relevant and sensible questions regarding VB.NET,
share your knowledge and expertise, share codes and techniques.

Post question on HOW TOs:
How to do this or that, ill supply bits of code to accomplish basic tasks.

Ill be posting series of samples leading to complete applications,
your suggestions are encouraged.
These samples will contain codes relevant to other tasks as well.

Platform = VS2003 to VS2012

i suggest learn and get the feel of VB.NET/VISUAL STUDIO IDE first before posting questions,
so that we can talk on the same page.


Topics:
VB.NET Winforms (not Web Applications)
ADO.NET as applied in VB.NET
Crystal Reports on VB.NET
SQLServer as used in VB.NET
MSAccess as used in VB.NET
Classes
UserControls

Technologies:
Serial - like using SMS, Barcode and other hardware
TCP/IP - chat applications, sockets, internet applications
MSMQ - message queuing
Remoting - executing assemblies in other computer
WebServices - using webservices in windows forms
Multithreading - executing more than 1 process at the same time

I currently use Visual Studio 2008 only, but basic codes will apply to all versions

Please do not ask for a complete system,
instead use the codes and assistance that you will find here
to build your own system.


***Thanks to moderators, STICKY na ang thread!

Lets share knowledge so that we can be a more flexible and well rounded programmer. Be it for school or work.

meron sila sample code sa "Sample Program" ng SDK. modify nyo nalang or pm me email. send ko sa inyo.

NOTE: vs2005 yung nasa sample nila.

pwede yang ganyan. permanently. but if runtime naman, ang ginagawa ko. ni rereload ko ang items ng combobox.

' fetch updated items here

combobox1.datasource = yourDataTable
combobox1.displaymember = "yourColumn"
combobox1.valuemember = "yourValueOrID"

 

[patrickkillua]

Gud Day, pls give me references,tut,tricks kung pano ang multi-user ng vb.net application sa LAN. TIA, and some reference's related in bank report's using VB.net

Based on Multi User.. User must have a role.. ex Admin,Sales etc..on database.. then tag/link it on your user..
Regarding to those report you may use built-in Report of VS .. "Crystal Report".
For reference just explore the rest of the page...

May mga alm po ba kung school that provide seminars in MSSQL advance.. (Replication/Mirroring) ?
or any that is related on VS or .NET?
