• Visual C# sentence case string

  How to convert uppercase string to sentence case string in C# e.g. input: HI ALL! I'M A NEWBIE. PLZ HELP! output: Hi all! I'm a newbie. Plz help! Here, I just wrote this as this made me curious.  I know this could probably be done a lot better by iterating over a chararray and changing the case depending on flipping a bit to indicate it was necessary but I was lazy and used strings: /// <summary> /// Represents a paragraph in English /// </summary> public abstract class Paragraph { /// <summary> /// Convert a string in arbitrary case to English sentence capitalis ...Show All

• Windows Forms How can I alter the property of the main form control from a secondary form?

  Hello, I want to change the BackColor property, for instance, of a control belonging to the main form from a seconday form. How can I do that Please help. Thanks. I'm not an experienced C#'er, but I would try this. If the secondary form was created by the main form, saying secondform.Parent should get you the main form (Possibly you'll need more .Parent, but keep working your way up). Then TypeCast to the main form's type. Then put a period, the controls name, and the property (in your case BackColor); EX: MainForm amf; SecondForm asf; Do ((MainForm)asf.Parent).controlname.Backcolor ...Show All

• Windows Forms Docking Problems

  I have a form with a menu and a toolbar, a splitter panel and other controls in the splitter.  If I dock the splitter, it slides up under the toolbar and the menu bar. I put the menu and toolbar into a panel and docked that panel to the top. then dock the splitter to fill or to the left. Fill puts the splitter under the top panel and left moves the top panel to the side.  Is there an attribute I am missing to prevent this   Suggestions Thanks Glen I know I'm late on this post (new to this section of the forum), but even another way is to open the "document outline" (found under the view menu in "other ...Show All

• Visual Basic Audio Spectrum

  Hi, i'm writing an app, and i would like it to have support for the windows media player activeX control, but i would like it to be hidden, and my application will show all the information, and custom buttons. Now i have all that done, but i would really like to get an audio analyzer put in my app, that is to say a graphical representation of the frequency of the sound on each channel.

• Visual Studio 2008 (Pre-release) ToQueryable() - Does it cause a query execution?

  From what I've been able to tell, calling ToQueryable() on the results of a "var x = (query)" operation doesn't actually invoke the execution, it simply wraps the contents of the expression tree generated for (x) inside an IQueryable<T> type. I just wanted to confirm here that calling ToQueryable() isn't going to give my query a case of the dreaded "premature query syndrome" , and that its just wrapping the deferred query in some more layers, and not going out and making the database call. Correct - ToQueryable() does not invoke x.GetEnumerator(): If x is IQueryable, then ToQueryable() returns x. If x is no ...Show All

• Visual C# Center picturebox in Panel with AutoScroll

  Center picturebox in Panel with AutoScroll...at runtime. If the picturebox anchor is not set to top,left AutoScroll won't appear. Any cure for this I have different size images. Most are larger than the control space...so AutoScroll comes in handy. When an image will fit, or is much smaller I want to center it in the panel that is set to fill. (rather than have the smaller images in the top left position of the panel). (This actually should be posted in Windows Forms general forum!) I wrote a piece of sample code that does exactly what you want, but I took a slightly different approach: I create a sub panel dynamically and s ...Show All
