Fiddler - NetMon on steroids

http://www.fiddlertool.com/fiddler/ Fiddler is a HTTP Debugging Proxy which logs all HTTP traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP Traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler is designed to be much simpler than using NetMon or Achilles, and includes a simple but powerful JScript.NET event-based scripting subsystem.

Multi-monitor task bar

This a truly cool app if you have multiple monitors. It allows you to create a seperate taskbar on your 2nd monitor (and even supports a 3rd monitor). http://www.mediachance.com/free/multimon.htm

ArcObjects AlterSpatialReference does not work

ESRI ArcObjects If you have attempted to use AlterSpatialReference and it does not seem to work then most probably the file is in use. If you attempted calling it from ArcCatalog, then check to see if the image is not loaded in ArcMap or ArcScene or is being used by some other application. In code, if you attempt to set the spatial reference then you need to set the GeoDatasetSchemeEdit to null (or nothing in VB). Here is an example using VC++ IDocumentPtr ipDoc; ipApp->get_Document(&ipDoc); IMxDocumentPtr ipMxDoc(ipDoc); IMapPtr ipMap; ipMxDoc->get_FocusMap(&ipMap); ISpatialReferencePtr ipSpatialReference; ipMap->get_SpatialReference( &ipSpatialReference ); IWorkspaceFactoryPtr ipWorkspaceFactory; ipWorkspaceFactory.CreateInstance(CLSID_RasterWorkspaceFactory); IRasterWorkspacePtr ipRWorkspace; IWorkspacePtr ipWorkspace; hRes = ipWorkspaceFactory->OpenFromFile(CComBSTR(strResPath), 0, &ipWorkspace); ipRWorkspace = ipWorkspace; IRasterDatasetPtr ipRasterDataset; IRasterPtr ipRaster; hRes = ipRWorkspace->OpenRasterDataset (CComBSTR(strResFileName), &ipRasterDataset); VARIANT_BOOL varCanAlter; if ( (ipSpatialReference != NULL) && (ipRasterDataset != NULL) ) { ((IGeoDatasetSchemaEditPtr)ipRasterDataset)->get_CanAlterSpatialReference(&varCanAlter); if (varCanAlter == VARIANT_TRUE ) { ((IGeoDatasetSchemaEditPtr)ipRasterDataset)->AlterSpatialReference(ipSpatialReference ); } } ipRasterDataset = NULL; //this is important - otherwise Spatial Ref wont be set //reopen raster dataset hRes = ipRWorkspace->OpenRasterDataset (CComBSTR(strResFileName), &ipRasterDataset); //...continue processing the raster

Assigning properties to delegates in C#

Assigning properties to delegates in C# - this cannot be done. So if you wanted to select a property to use at runtime, then you can use a method similar to that shown below. public class Class1 { string s1 = null; string s2 = null; private PropertyInfo _prop; public Class1(int iPropToUse) { if (iPropToUse == 1) _prop = typeof(Class1).GetProperty("PropOne"); else _prop = typeof(Class1).GetProperty("PropTwo"); } public string PropOne { get {return s1; } set {s1 = value;} } public string PropTwo { get {return s2;} set {s2 = value;} } public void SetStringValue(string s) { if (_prop != null) _prop.SetValue(this,s,null); } public string GetStringValue() { if (_prop != null) return (string) _prop.GetValue(this,null); else return "no property set"; } static void Main(string[] args) { Class1 o1 = new Class1(1); o1.SetStringValue("Hello"); Console.WriteLine(o1.GetStringValue()); Class1 o2 = new Class1(2); o2.SetStringValue("World"); Console.WriteLine(o2.GetStringValue()); int i = Console.Read(); } }
