WinHttp.WinHttpRequestオブジェクトを使って使ってHttp PostでByte配列のデータを送信するExcel VBAプログラムです。 WinHttp.WinHttpRequestを使う際には、 1. ExcelのMicrosoft Visual Basic エディタのメニューバーから「ツール->参照設定」とたどる。 2. 表示されたダイアログからMicrosoft WinHTTP Serviceにチェックを入れる。 という手順が必要です。 Byte配列をPOST Private Const BOUNDARY As String = "SOMETHING" Private Function httpPostServletByte(url As String, data() As Byte) As Byte() On Error GoTo e Dim WinHttpReq As WinHttp.WinHttpRequest If (WinHttpReq Is Nothing) Then Set WinHttpReq = New WinHttpRequest End If WinHttpReq.Open "POST", url, False WinHttpReq.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded; boundary=" & BOUNDARY WinHttpReq.send data Dim response() As Byte: response = WinHttpReq.ResponseBody httpPostServletByte = response Set WinHttpReq = Nothing Exit Function e: Set WinHttpReq = Nothing Debug.Print "httpPost Error:" & Err....

ADODB.streamオブジェクトを使って文字列をByte配列に変換するコードのサンプルです。 ExcelVBAでADODB.streamを使う際には、 1. ExcelのMicrosoft Visual Basic エディタのメニューバーから「ツール->参照設定」とたどる。 2. 表示されたダイアログからMicrosoft ActiveX Data Objectsにチェックを入れる。 という手順が必要です。 文字列からByte配列へ Private Function ADOS_EncodeStringToByte(ByVal cset As String, ByRef strUni As String) As Byte() On Error GoTo e Dim objStm As ADODB.stream: Set objStm = New ADODB.stream objStm.Mode = adModeReadWrite objStm.Open objStm.Type = adTypeText objStm.Charset = cset objStm.WriteText strUni objStm.Position = 0 objStm.Type = adTypeBinary Select Case UCase(cset) Case "UNICODE", "UTF-16" objStm.Position = 2 Case "UTF-8" objStm.Position = 3 End Select ADOS_EncodeStringToByte = objStm.Read() objStm.Close Set objStm = Nothing Exit Function e: Debug.Print "Error occurred while encoding characters" & Err.Description If objStm Is No...
