在同一台電腦安裝ArcGIS Desktop和ArcGIS Server後,會有一個AppLockMgr進程,會導致Desktop程式開啟、顯示和查詢檔案資料及其緩慢,上網查了一下,ESRI官方的說法是由於DCOM的使用權限設定的問題,解決辦法如下:Problem: Performance of ArcGIS Desktop or ArcReader is very slow when installed on the same machine as the ArcIMS ArcMap

內容摘要很多線劃圖資料進ArcSDE庫中都會有些對象轉換不進去。這些對象有很大一部分是由於資料本身有自相交的情況。如果這些線劃圖資料只是用來做底圖,而不需要做對象分析。則可以採用資料簡單化操作後再轉換入ArcSDE中。具體操作如下例子:流程說明Private Sub SimplifyPolyLine(pPolyline As esriGeometry.Polyline) '通過QI取得線對象的拓撲操作介面 Dim
Geoprocessor gp = new Geoprocessor(); gp.OverwriteOutput = true; IFeatureLayer inputfeaturelayer = pMap.get_Layer(0) as IFeatureLayer; IFeatureLayer cliplayer = pMap.get_Layer(1) as IFeatureLayer;
