• .NET Development Detecting remove lock event on file

  I have the following problem: We have to write an application that acts on changes on files. For example editing a word - file. We achieve this using the FileSystemWatcher from .NET 2.0.  When the word-file is saved the events correctly trigger, but the files are locked, which causes our action to fail, but this is not the problem. But when the user closes the word-application. The application release the lock,but  we can't seem to catch this event so we could run our actions then.   Does anybody has as solution Thx, gert So if there is no explicit windows way to detect a lock, we are back to an old-school trial and error approach to find out whether there is a lock ...Show All

• Visual FoxPro pass contents to C#

  hi! this is sort of connected to my other post regarding Foxpro and C#.. in the foxpro program i will type in a name and when i call the C# program it will also contain the name entered in the foxpro program. is this possible How can i do this thanks! From C#, you use ADO.NET, connect to the database that contains the data and query it. There is nothing to it, and it is not related to VFP. A SQL Server database is a repository of data. Which client you use to access that data is immaterial to SQL Server. So it is perfectly OK to insert data from a VFP front-end and retrieve it from C# as you want to do. If you are unfamiliar with C# and ADO.NET, there are forums here for them where you can ...Show All

• Smart Device Development Button Control

  I apologize if this is too simple an issue, but I am just beginning a project targeted at smartphones (e.g., Treo 700w).

• Windows Forms Strange RectangleF behaviour

  Hi, I'm experiencing seeing some rather odd behaviour with RectangleF in release mode. Consider the following unit test: [Test] public void RectTest() { RectangleF rect = new RectangleF(0.2f, 0.0f, 0.8, 0.0f); //RectangleF rect = new RectangleF(0.25f, 0.0f, 0.75f, 1.0f); if (rect.Right > 1.0f) throw new Exception("rect.Right > 1.0f"); } When I run this test with the first rectangle initialization, it throws an exception. However, with the second rectangle, it does not. More generally, it seems that for x=1/n, and width=1-(1/n), where n is odd, the exception is thrown, but when n is even, it isn't (that rule starts to break down around n=25). Note also that no exception is ever thrown in debu ...Show All

• SQL Server Where to find Reporting Services News

  I have read an article about Reporting Services that was rather critical regarding a number of topics. But, this article was from 2005 and I assume that there have been some improvements in Reporting Services since then. Or If so, are there any good places where you can find the news I haven’t been able to find a good site for news in, in this case, Reporting Services. Generally I search blogs.msdn.com, www.technorati.com , and blogsearch.google.com. The product teams blogs usually have the most up-to-date information. Here is one blog: http://blogs.msdn.com/bimusings/default.aspx One entry has lots of useful information. The Tigers Have Spoken (Reporting Services White Papers) I've got a virtual cor ...Show All

• Visual Studio Express Editions Dataset Not Writing to Database

  Ive set up a small database project. I created it using the wizards, and used the dragging and dropping of the table in the data sources view to get the fields and buttons on to the form. That is all I have done, no custom code or anything. But it doesnt work. The data is written to the dataset as it is all stored while the program is running in VB. However if you close it the data is not written to the database (I did press the save button). I dont understand why this doesnt work as I have touched it myself. Any ideas on how to fix this problem Thanks in advance Code is beneath Public Class Form1 Private Sub Table1BindingNavigatorSaveItem_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Han ...Show All
