In this article, we take a VB project as example.

1. Install SCM Anywhere Standalone Client on your machine. The COM SDK comes with SCM Anywhere Standalone Windows Client.

2. Please add 2 dll files, "SCMSSDK.dll" and "SCMS.Core.dll", to the project. In Visual Studio | Project | Add Reference | Browse tab, browse to the SCM Anywhere Standalone Client installation folder, highlight and select "SCMSSDK.dll" and "SCMS.Core.dll", and click OK.

3. You can use the ConnectToServer() function to connect to your SCM Anywhere Standalone Server, and then use the CheckInFiles() function to check in the files.

Here is a sample in VB:

Imports com.dynamsoft.scm.SCMSDK

Public Class Form1

    Dim sdkObject As New SCMSSDK()
    Dim bobjTrial As New com.dynamsoft.scm.client.pub.common.basedataobjects.BoolObject

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

        'connect to server
        ResultValue = sdkObject.ConnectToServer("127.0.0.1", 7771, False, "admin", "", 0, "", 0, "", "", bobjTrial, iobjLeftTrialDays, iobjLeftPasswordDays, strobjError)

        If ResultValue <> 0 Then
            MsgBox("Failed to connect to server. " + strobjError.GetValue())
        Else
            MsgBox("Succeed in connecting to server.")
        End If

    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        'check in
        listFilesFullNameToCheckIn.Add("$/branch/1.txt")
        ResultValue = sdkObject.CheckInFiles("Default", listFilesFullNameToCheckIn, False, False, "check in a file", listIssueID, True, 2, listItemOperateResults, bConflictExists, strobjError)

        If ResultValue <> 0 Then
            MsgBox("Failed to check in. " + strobjError.GetValue())
        Else
            MsgBox("Succeed in checking in.")
        End If
    End Sub
End Class
