• TimmayB File search

  Is there anything in the .net library that would allow me to search for a file on a pc, ie. sql2005 installer I need a method that allows me to search specific locations for specified files rather than just checking a predefined path ie File.Exists(filename) as the user may have moved those files to a different location. ta Mark so I could just set the folder path as the C:\ drive and let it search that drive and all its folders for the application ... Indeed, correction, multiple parent directories... However, to search multiple directories you'd have to implement yourself. Just keep in mind that this could take a heck of a long time, so it'd probably ...Show All

• lecedre Validating XML Uploaded via FileUpload (ASP.NET)

  My webform allows users to upload an XML file, which I want to validate as part of a custom validator before doing anything with. This should be easy, right Problem: The XmlReader is unable to find a root node when accessing the FileUpload.PostedFile (or the equivelent Request.Files[0].InputStream). What's curious is this: I can load the stream directly into an XmlDocument without problem. I can also save it to disk and load it into a reader without problem. (So yes, I am sure that the root node exists in the filestream). Here's the basic code if anyone wants to try this out: XmlReader catalog = XmlReader.Create(Request.Files[0].InputStream); while (catalog.Read()) {} catalog.Close(); This would respond to something like: ...Show All

  I am having a hell of a time trying to solve this error. Stack trace is at the end. I am using WSE3 with a custom DLL to perform compression on the message body. The DLL is called WSCompression and can be found here: http://weblogs.shockbyte.com.ar/rodolfof/ When I test my web service through local web browser, the web service executes just fine. Its when I try to invoke the service from a fat client that I get the error listed below. If I change my IIS settings to be FullTrust, everything works fine, so I know its not my client.

• dclements CLR and thread deadlocks

  Hello, I'm hosting the CLR (.NET 2.0) in an unmanaged C++ app. The CLR is used for calling C# plugin functions through IDispatch. The C# plugins are COM visible classes and are created from the app main UI thread. They are mostly used for accessing the app through a COM primary interop assembly generated with TLBIMP.EXE. The interop between C# and the app is achieved through the default Microsoft COM wrappers. This is all working fine but I'm having a problem when the C# functions are called by the app from a worker thread. At this point the CLR attempts to interop with the app via the UI main thread which is causing a deadlock because that thread is locked while the worker thread is executing. From what I see in the call stack (b ...Show All

• jeffery chan securing server-side types in IPC remoting

  I have an application that uses .NET Remoting over IPC. I have a lot of code that distills to the following pattern. (Assume each interface/class defined in different assembly.) public interface ILimitedAccess {} public interface IFullAccess : ILimitedAccess {} internal class MyClass : IFullAccess { } Server-side components use IFullAccess. Client-side components use ILimitedAccess. In scenarios where the server and client are 2 separate machines, clients are effectively prevented from using the IFullAccess interfaces by witholding the .NET assembly that declares them. Unfortunately, I am using IPC and all of my .NET assemblies are on the same machine. This means that client-apps (which can be written by 3rd parties) can simply load ...Show All
