• Smart Device Development How to access form controls from outside the form class

  Hello, I have got a question that I believe must be quite basic. I am currently working on a project that involves developing an application on a PDA using .Net Compact Framework 2.0 in C#. Here is my problem: After performing the InitializeComponent(), I have to enable many device features such as its barcode scanner, battery status trigger.... . In order to well seperate the view with the buisiness logic, we would not like to write all these "device initialization" codes in the form class but in separate classes. The problem is that some of these initialization methods require to access a form control (e.g. the scanner should display the barcode it reads in a textbox, the battery status should be displayed in a label...).

• Software Development for Windows Vista What do I need to develop a video player?

  Hi/Hello I'm just a designer who wanna enter into a programming world, and I will be happy for the rest of my life if I will ever be able to create my own video player.

• SQL Server Pausing Log Shipping Plans

  We are doing an IP Restructuring on our DR site over the weekend due to some business and management requirements.I actually have 2 questions. I have implemented log shipping plans for our databases. Which means I will have to pause (disable) my log shipping plans while this is being done and resume (re-enable) after everything is comlete. Any insights on what else I need to do apart from these My second question is this. I am generating transaction log backups every 15 minutes and is averaging at 350MB (this much data every 15 minutes - not to mention that I've got around 40+ databases, all configured for log shipping just for this instance alone). My alert threshold is 45 minutes. My log shipping plan for one database starts failing pr ...Show All

• SQL Server Is SQL Server CE really the solution?

  Hi,   So far, with other programming platforms, I used to have the facility, embedded within application .exe, to:        1- Interface with already existing "multi-user" database (ex: Oracle, Access, etc.)        2- Create/access "local"/"Single-User" files for processing purposes.  (try to minimize network trafic...)   So far, I've read a lot about SQL Server products (SQL Server, Sql Server Express, SQL Server CE), at least all articles I could find, and would like to have your opinion on what would be the best approach        1- What SQL version to use for "multi-user" databases &n ...Show All

• Gadgets How do I do this: ?

  There are several things I want to do. First off what I am doing is reworking a gadget that was made to play mp3s from WMP, this gadget also displays the song track, artist & album. The problem I have is that I don't find it flexible enough and it's just ugly looking to boot, I have so far reworked the interface so that it is much nicer looking visually tho still needs some work, got rid of the album art in the interface BUT I still want to be able to display the art but in a flyout which while I can get the flyout itself to work it does not display the album art and would like to know how to reference the working javascript that was in the parent window/gadget to display the image in the flyout.

• SQL Server Query timeout

  I need to figure out if my query is timing out due to row lock contention. The SqlException trapped in my client C# application contains Error Number 1205 but sometimes it contains -2. I guess the SqlCommand timeout and the server timeout are the two possibilities. Is there a definitive way to find out that the SqlException was thrown due to one of these two reasons Because if it's some other reason, I want to excute a different logic.
