AWSについて

今日、初めて、AWS3.0（Amazon Web Service)をVS.NETで呼んでみました。

会社で、ASP.NETで呼んでみたところ、どうも日本語のkeywordがうまくいかなかったのだが、家で再度、WinFormで呼んでみると、あっさり検索できた。
でも、まだAinSearchに関してはうまくいっていない。

ソースは以下。

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ws As New AmazonSearchService
Dim request As New KeywordRequest
Dim productsinfo As ProductInfo
request.devtag = "****"
request.tag = "webservices-20"
request.keyword = TextBox1.Text
request.mode = "books-jp"
request.type = "heavy"
request.locale = "jp"

Try
productsinfo = ws.KeywordSearchRequest(request)
Catch ex As Exception

End Try
ws.Dispose()
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click　　'←これはうまくいっていない。
Dim ws As New AmazonSearchService
Dim request As New AsinRequest
Dim productsinfo As ProductInfo

request.asin = TextBox1.Text
request.devtag = "****"
request.mode = "books-jp"
request.type = "lite"
request.locale = "jp"

Try
productsinfo = ws.AsinSearchRequest(request)
Catch ex As Exception

End Try
ws.Dispose()

End Sub
