pwede pong ilagay nyo sa button nyo yung ganito..
sample lang po..

Code:

foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.Cells[CheckBoxColumn1.Name].Value = true) { ///kunin mo yung serial number } }

boss salamat sa pagreply ... eto sinubukan ko, kaso ung huling na i-check na checkbox lang ang na sesave ng paulit-ulit kahit pa marami nmng checkbox ang naka check ...

PS: kung ilan ung checkbox nga naka check ganun rin kadami ung entries sa database ng huling checkbox na nai-check...

Code:

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
       

        Dim serialnumber As String = DataGridView1.CurrentRow.Cells("SerialNumber").Value
        Dim siteid As String = Main.StatusBar1.Panels(2).Text
        Dim connection As New SqlConnection
        Dim cmd As New SqlCommand
        connection.ConnectionString = "Data Source =TOBZ-PC; Initial Catalog =Glowb; Integrated Security =SSPI;"

        For Each row As DataGridViewRow In DataGridView1.Rows

            If row.Cells(Column1.Name).Value = True Then

                connection.Open()
                cmd.Connection = connection
                cmd.CommandText = " INSERT INTO [Equipment Request](SerialNumber, SiteID) VALUES('" & serialnumber & "', '" & siteid & "') "
                cmd.ExecuteNonQuery()
                connection.Close()
            End If

sir mukhang hindi mo nilagay yung value ng "serialNumber" na galing dun sa row... tama ba?

dapat po ninyong palitan yung laman ng variable na to sa loob ng if statement..

hindi ito yung saktong code pero nandito yung idea..

Code:

If row.Cells(Column1.Name).Value = True Then
serialNumber = row.Cells(ColumnForSerial.Name).Value

///other codes

data type mismatch in criteria expression po ang error nya...nalilito n ko!!!phelp nmn plz

wala ka ba numeric na field?

and also whag mo gawin to

cmd = New OleDbCommand("insert into empmaster values (@empno, @empfirst, @empmiddle, @emplast, @empaddress, @empcontact, @empemailid, @empgender, @empdob, @empbloodgroup, @empdoj, @empnamebank, @empposition, @empbankbranch, @empbankno, @empimage)", con)

sa INSERT specify the target field

INSERT INTO TABLE1 (Field1, Field2) VALUES( @Field1, @Field2)

mas malinaw, kasi pag nag add ka ng field sa table lagot na yang code mo

now yung error is
"data type mismatch"

alam mo siguro meaning neto?

tignan mop baka nag insert ng string sa numeric field
or nag insert ng null sa field

kasi baka may emty or un initialized variable or control ka dyan

try mo ganito sa string field
cmd.Parameters("@empno").Value = "" & txtempno.Text

Sir, anu-ano po ba ang mga String function na available sa vb.net na wala sa vb6? or nasa vb6 na wala sa vb.net? kasi po Right() function lang nakita ko. gusto ko po kasi matutunan sa vb.net ung string manipulation. marunnog po ako sa vb6 ang gusto ko po sana ay malaman ung mga function na importante na pwdeng maiapply sa system. O kaya naman po kahit ung mga comparison ng mga function sa vb6 to vb.net

halos lahat ng vb6 function meron sa vb.net :

vb6 : left()

vb.net : microsoft.visualbasic.left()

ericgmejia said:
I made this thread for all programmers starting their adventure on 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 VS2010

i suggest learn and master the VB.NET IDE first before asking 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

Suggested Third Party Tools:
DevXPress 2009 Free Edition
SQLServer 2005 Express Edition

Suggested references:
http://www.homeandlearn.co.uk/net/vbnet.html
http://www.java2s.com/Tutorial/VB/CatalogVB.htm

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.

***Can somebody suggest to the moderators to make this thread sticky if you find it useful in your studies or work.

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