在IIS7的環境佈署 Reportviewer 卻無法正常顯示的問題

由於IIS7新架構的關係, 導致ReportViewer的報表成果無法正確展示在頁面下，目前可透過兩種方式解決。
第一個是將網站所屬的應用程式集區的管線模式由整合式變更為傳統。
第二個則是設定網站的 處理常式對應，程序如下：

1. Go to IIS 7 admin screen.

2. Go to your Virtual Directory (Application actually).

3. Click on Handler Mappings.

4. Click on Add Managed Handler.

5. Add the following Handler:

Request Path: Reserved.ReportViewerWebControl.axd

Type: Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a  (This can be selected from the drop down, just make sure you select the correct one).

Name: Reserved.ReportViewerWebControl.axd

Insert geometry 前確認是否合法

之前為專案寫了一個 shapefile 匯入程式, 匯入目標是PostgreSQL資料庫， 後來在資料庫中進行 intersect 時發生空間分析的錯誤，經過追查發現有些Geometry有 self-intersection 的狀況，接著還好在 google 找到解決方案

以上這段是要在PostgreSQL裡建立一個function，然後在進行 insert 動作的時候, 讓要 insert 的 geometry 先丟到這個function進行檢查並重整後, 回傳正確的 geometry。結束
