Dynamically Centering a Windows Forms Label Control

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :ASP.Net
 
I'm working on an athletic workout journal application that will include an Interval / Countdown Timer. I plan to build several versions of this application in different technologies (WPF, Web, Phone) but I'm building the first version in Windows Forms. I want the user to be able to dynamically set the size of the "Stopwatch" display font, then resize the form and have the text re-center in the form, taking into consideration the new font size. Stuff like this is easy in HTML, but not so much in Windows Forms. Though I'm still in the early stages I thought I'd share the bit of math that I've come up with and invite any suggestions you might have. Code Snippet using System.Text; using System.Windows.Forms; namespace WorkOutTimer { public partial...(read more)

Cutting Edge: A New Grid Control in Windows Forms

  

Grid controls are essential in many of today's apps. Until now, though, most developers using Visual Basic® have had to buy third-party components to get an effective, easy to use grid component. The Windows® Forms DataGrid turned out to lack too many features for the average developer.

Web-Aware Apps: Build Hyperlinks into Your Client App with the Windows Forms LinkLabel Control

  

LinkLabels are Windows Forms controls that enable a user to hyperlink to a URL that points to either the Web or the local directory system. While the SDK documentation discusses the control, it does not demonstrate how linking is accomplished, nor does it outline the power and flexibility the control provides. This article fills those gaps, showing how to link using the LinkLabel control. It also shows the flexibility of this control for the programmer using the .NET Framework. In addition, the author covers the large number of properties that allow you to customize your controls and accurately place them. Their built-in behaviors are also discussed, along with their use in both Visual Basic .NET and C#.

Windows.Forms.Label size change issue

  

Issue:

In a Windows Forms application developed with VB2008 Express, Label controls change size the first time the .Text property is updated.

Details:

On a Windows XP Pro SP3 system where the app was developed the labels retain the size set at design time.  On other systems, one also Windows XP, one Windows 7, labels shrink (all to the same size independent of content) the first time their .Text property is updated.  Labels that do not have their .Text property updated retain their design size.

Additional information:

The labels all occur within a FixedPanel of a SplitContainer.
Salient properties for the Label controls:
Anchor: Top, Left
AutoSize: False
BorderStyle: FixedSingle
Dock: None
Enabled: True
FlatStyle: Standard
Image: None
Locked: False
Margin: 0,0,0,0
MaximumSize:

Setting trust level for windows.system.forms.browser control

  

Hi All,

I am using a browser control in my WPF application. The users of this application will be using this control for viewing content that could contain malicious scripts. I want to set the Trust Level so that none of the scripts should be executed. I have added the Attribute to the method that creates the Browser control. I dont think its working though. Any thoughts on how this can be done?

Is Dispatcher.BeginInvoke really NOT thread safe, while the old System.Windows.Forms.Control.BeginIn

  

Hello.

 

System.Windows.Forms.Control.BeginInvoke is documented as thread safe (in fact, BeginInvoke , EndInvoke , Invoke , InvokeRequired , and CreateGraphics are).

Great!

 

But in WPF, Dispatcher.BeginInvoke is not documented as thread safe. Which would appear to me as a regression (and not really convenient, to be honest).

Was it only forgotten in MSDN documentation, or should I really use external locking to prevent the dispatcher to get lost in its messages and priorities?

 

 

Thanks. ;)

Application Architecture in Windows Forms 2.0

  
Applications have special support in Windows Forms. For starters, you can manage and tailor your application's lifetime, and, when the work flow is disrupted by an unhandled exception, you can choose from several methods of response. Then, there are several application models that you can employ, including Single Document Interface (SDI) and Multiple Document Interface (MDI) applications, each of which can support either multiple-instance or single-instance mode, the former the VS05 default and the latter requiring special consideration. All applications, however, can discover and use a wide variety of information about the system and environment they execute in.

Application Architecture in Windows Forms 2.0-Single-MDI Applications

  
Consider an MDI application like Microsoft Excel; files opened from the file system (by double-clicking) are all opened as separate child windows within the parent Excel window.7 For the first instance of an MDI application to open a new child window to display the file that was passed to the second instance of the application, the second instance must be able to communicate with the initial instance.

How to programmatically add controls to Windows forms at run time by using Visual C#

  
Create a Windows Forms Application
Start Visual Studio .NET or Visual Studio 2005 or a later version, and create a new Visual C# Windows Application project named WinControls. Form1 is added to the project by default.
Double-click Form1 to create and view the Form1_Load event procedure.
Add private instance variables to the Form1 class to work with common Windows controls. The Form1 class starts as follows:

How to Localize Windows Forms and Change the Language at Runtime

  
Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project
