• Hansen Steve Page Load Firing Twice

  I converted to 2.0 and now hte page load fires twice on my web sites. I understand there may be a place where the converted inserted code that loads the page twice, but I can't find it in the code behind. I'm using vb. Thanks. Not a silly question at all. I am seeing the same behavior on two of my pages involving a CrossPage Post. It seems like if I do not go through the same logic to initialize all the controls twice (which is potentially a lot of overhead) the page won't look right. On the first Page_Load, Page.PreviousPage is set; the second time around Page.PreviousPage Is Nothing, The page_load even somehow looked like... Private Sub Page_Load(ByVa ...Show All

• susanasusana [OT?] Programmatically refresh usb devices

  Hi All, I have a problem - I have written a .NET 2.0 program that allows me to automatically retrieve files from a Pocket PC (ipaq hx 2790) using RAPI. Unfortunately, if the ipaq is removed from the usb cradle while it is connected to ActiveSync, when it is replaced into the cradle it will not reconnect!!! Doing a "Scan for hardware changes" for USB devices from the Device Manager refreshes the connecting and the ipaq reconnects. Obviously I dont want the end user to have to refesh the usb this way if this problem happens, so what I want is a way to programmatically refresh the usb devices. (or if anyway knows what is the real problem here i would be grateful for a fix) Also if there is a better newsgroup for this questi ...Show All

• MongoBongo DataSet Copy/Clone

  Hi, I need to have a copy from one Dataset created at the Form level. I'm using the TableAdapters and BindingSource Objects also. In some cases I need to check and verify if a specific row exists in my DataSet. How can I do it using the DataSet Is there any other way (BindingSource.Find) My table have 3 fields for the table key. I am assigning the BindingSource to a DGV.DataSource to display it. This specific BindingSource as its DataSource and DataMember related to the original DataSet. If I want to consult a specific row on the DataSet this will change the Position on it, true This would mean that the DGV display would also change, true I don't want that to happen. Can someone help me Thanks, ...Show All

• kuha60 File In Use error, Whilst using InterfaceCodeCompiler.CompileAssemblyFromSource()

  Through these samples of code is what leads up to the error. It happens in the Compile Console Method (1st one Below). I receive a Console.dll; file is in use and I cannot figure out why... without that error, this would work flawlessly, how I want it to. Basically, when the user enters any character with a hyphen (-) as a prefix to it, in the textbox, hits process, in my console, it will attempt to save all that to a file (it automatically includes a fixed class & method, it just writes the command), and if there are any errors, it will display it in txtHistory, using the Add() Method (not shown). Anyways , the error occurs where it is in YELLOW, with a RED background, and in pretty big font, compared to the rest, so i ...Show All

• DzheiZee Serialization error with SqlConnection variable

  I'm getting a serialization error in ASP.NET when it tries to store one of my classes in the Session state. I marked the SqlConnection variable as non-serializable but it still tries to store it in the session state. My class looks like this: [Serializable] public class SqlServerDAL { [XmlIgnoreAttribute] private SqlConnection Connection; } Any ideas why this is happening even though I marked it with the XmlIgnoreAttribute Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'C ...Show All

• jepptje Strong names for assemblies

  Hello, I'm a new developer (in several senses of the word "new") and I am working on a large-scale internal project requiring testing of code written before I got here. I have already used the CLR profiler successfully on a production release of the product. However, the CLR Profiler is not giving me the information I really need (how long a process takes in real time); so I've written a short assembly that I've attached to certain methods in the project that writes out to an external file with a trace and other information. The problem that has arisen is, in one specific class, this assembly causes a build error, because it is not a "strongly named assembly." How exactly does one name an assembly strongly BTW. ...Show All

• Sweeps78 downloading/reading source code from websites

  I just got visual C#, had been using java, and am stuck trying to figure out how to read the source code from a public website. In java it was...

  I need a way to check, using Javascript, if the user has added the domain as a Trusted Site. We sell different kinds of content management tools and similar products to our customers.

• HeathM How to monitor an I/O event from a separate process?

  I have a third party application that reads a file.  I am trying to create an new application that writes updates to the file after that 3rd party app reads it.  Is it possible to monitor file access from .NET on the O/S level to trigger my application to syncronize read and writes over time   How would you do it   If this is not possible, how would you solve this problem other than recreating the third party application (which is not realistically possible) I/O monitoring seems to be possible, as there are programs like http://www.sysinternals.com/Utilities/Filemon.html  that does it.  I just need to know how they hook into Windows and trigger an event ...Show All
