I created a toolbar using ArcObjects 10.0 which does some heavy processing in the onClick event of the only button it includes. It works fine however it works only once. If I click again on the button nothing happens. To run it again I need to restart ArcMap and run it again. I cannot understand this behavior?
i am working for Electrical Data set, which is having a tree like network, and network should be downstream, there are some lines which lies opposite direction in it. need to identify those lines. below is the example.
below is the process flow i am using in my tool.
Below is the Code linked to click event of the button:
public WrongDirection()
{
//Setting Status Bar
IStatusBar pstatusbar = ArcMap.Application.StatusBar;
pstatusbar.ShowProgressBar("Running wrong Direction..", 0, 17, 1, true);
try
{
//Define IMxdocument and Imap
IMxDocument mxdoc = ArcMap.Application.Document as IMxDocument;
IMap map = mxdoc.FocusMap;
if (map.Layer[0] == null)
{ return; }
// Setting GXDialog for Output
IGxDialog pGXDialog = new GxDialogClass();
pGXDialog.AllowMultiSelect = false;
if (pGXDialog.DoModalSave(0) != true)
{
pstatusbar.HideProgressBar();
return;
}
pGXDialog.ButtonCaption = "Save";
pGXDialog.Title = "Save Wrong Direction Points Feature";
pGXDialog.RememberLocation = true;
IGxObjectFilter gxobjFilter = new GxFilterShapefilesClass();
pGXDialog.ObjectFilter = gxobjFilter;
pGXDialog.DoModalSave(0);
IGxObject pGxObject = pGXDialog.FinalLocation;
String s, Fp;
s = pGXDialog.Name;
Fp = pGxObject.FullName + "\\" + s;
pstatusbar.StepProgressBar();
