• Visual Studio 2008 (Pre-release) Is the pseudo SQL syntax necessary?

  Current LINQ syntax is like this: var upperLowerWords =         from w in words         select new {Upper = w.ToUpper(), Lower = w.ToLower()}         where w.StartsWith("a"); But I think that this is unnecessary breeding of C# with SQL. I believe that combination of methods with lambda calculus would be better: string[] words = { "aPPLE", "BlUeBeRrY", "cHeRry" }; var selectedWords = words.Select(    w => {return w.StartsWith("a")} ).Collect(    w2 => {return new {      Upper = ...Show All

• Visual C# Creating a Mouse-Pointer-Shy button

  Hi everyone, Am very new to C# and to programming altogether. After reading many ebooks and watching many learning videos on the subject I finally felt brave enough to mess around with some code. Not trying to do anything useful at this point, simply messing around. Am trying to simply make a button move to a *Random point within the confines of my form when a user *Hovers * their mouse pointer over the button. This is what I have so far: private void button1_MouseHover( object sender, EventArgs e) { button1.Location = new Point (40,25); } But as you can see, the new point is not random, it is specific.

• .NET Development J# doesn't support 64 bit?

  I'm getting my first 64-bit machine next week, so I thought I'd better start getting up to speed about 64 bit. I have a solution that has C# applications (WinForms and class libraries), as well as some J# class libraries. As long as the solution only contains C# projects, the platform configuration manager (that dropdown in the toolbar) says "All CPU", meaning it will generate platform-agnostic MSIL. But as soon as you add a J# project, it says "Mixed Platforms" and also adds "x86". Doesn't J# support 64-bit I thought it also produces MSIL ! Does this mean all my applications have to run in x86 Or is .NET smart enough to compile the C# ...Show All

  Could someone help understand how the listbox's item collection refreshes the listbox control when you exit the collection editor.  I have a usercontrol with a collection property, but I don't know how to refresh the usercontrol when I exit the collection editor during design time.  Thanks in adavance.

It uses some features that are not available in VB Express so I've ordered a Standard version of the software today. ...Show All

• Visual C# Specifyng "Font" With Trace File and Resource File Messages

  Hello ... I was wondering if there is any documentation on writing resource file strings to a trace file, and using a specific font. As a supplement/alternative ... is there any way to embed control characters for things like TABs in resource file strings to that you can clean up the output of a printed list of rows so they will start in the same location. For example: Phone1: 301 555-1212 // Tab between the colon and the first digit Phone2: 301 333-8877 // Same Phone3: 301 888-8888 // Same Thanks so much! ...Show All

  Hi, On W2K3 system I installed VS 2005 and I automatically got .Net FrameWork 2.0 installed. When I build an app it builds in .Net Framework 2.0.

• Visual Basic How does one hide a ListView column?

  Is it possible to hide a listview column I don't want to remove it, and I want to process the data in it. I just want to hide it. The problem is that the column will contain potentially sensitive information, and I want to be able to protect against shoulder surfers. The problem is, I cannot find a ListView.Columns( n ).Hide() method or a ListView.Columns( n ).Visible property. Is this possible to do, or do I just have to remove the column It doesn't seem like it should be all that hard. Thanks, Mark Warner. I don't think you can hide a column on a ListView, you either have to remove it or set th ...Show All
