• WinForms: How do I simulate button behavior on an image?

  - by Cheeso

  I have an extension of the winforms TabControl, it's draws an X on each tab to allow the user to close the tab. How can I similate button look&feel on that image? It's not a button, it's not even an image control. It's just been drawn there. Is there a way to draw an inset border on MouseDown and Raised on MouseUp? Would I be better off generating another image, for the "inset" phase? anyone done this before? Related: Simulate Winforms Button Click Animation But this question is different because he actually has a PictureBox control. I don't.

• What is the simplest, but solid, interface from WinForms to a SQL Server database?

  - by Greg

  Hi, If I wanted to have my data in SQL Server, but wanted to use a thick client WinForms application for users, what would be the best practice way to have calls occurring from WinForms to database? And how simple is this? I guess I'm trying to gauge to what extent there are issues with this approach and one needs to go for some (a) middle tier with web services, or (b) have to go asp.net or something. I really just have a simple app that needs a database and I'll only have a 10 - 30 clients on a LAN/WAN network that would be connecting in.

• Silverlight Vs. WPF Vs. Winforms What is good for specifically my purpose?

  - by Cyril Gupta

  I am about to start a new Windows applications and the contenders for the platform are: Windows Forms WPF Silverlight Now my experience with WPF at least in my last application was not very encouraging (the app failed to run on the deployment machines and I had to re-do it in Winforms). So my confidence is shaken here. My app is for mass-distribution (the last version had some 100,000+ installations). So I want to make absolutely sure that my users will be able to use it and enjoy it without any problems. I would love to create a nice interface, going the next step like a Flex or Silverlight, iPhone app, with animations and effects. So I would really like to go with WPF or Silverlight if I can. My needs are Good support for visuals and animation effects. Support for database connectivity. Support for printing (Is there an equivalent of PrintDocument in Silverlight) Must not suffer from deployment troubles. Silverlight is universal, but does it have printing support and good controls toolset? WPF has printing support and a nice toolset, but can I depend on it? Winforms is dated already and is not so impressive, but should I go with it anyway? Your advice would be appreciated

• Best way to databind a Winforms control to a nullable type?

  - by Steve Hiner

  I'm currently using winforms databinding to wire up a data editing form. I'm using the netTiers framework through CodeSmith to generate my data objects. For database fields that allow nulls it creates nullable types. I've found that using winforms databinding the controls won't bind properly to nullable types. I've seen solutions online suggesting that people create new textbox classes that can handle the nullable types but that could be a pain having to swap out the textboxes on the forms I've already created. Initially I thought it would be great to use an extension method to do it. Basically creating an extension property for the textbox class and bind to that. From my limited extension method experience and doing a bit of checking online it looks like you can't do an extension property. As far as I can tell, binding has to be through a property since it needs to be able to get or set the value so an extension method wouldn't work. I'd love to find a clean way to retrofit these forms using something like extension methods but if I have to create new textbox and combo box controls that's what I'll do. My project is currently limited to .Net 2.0 due to the requirement to run on Windows 2000. Any suggestions?

• How do I write code that doesn't suck? [closed]

  - by Afnan

  My friends and I would like to write a C# desktop application, and would like some guidance on how to make sure the code base is professional and well-kept. Should we use classes or interfaces for our inheritance patterns (which is better)? What are the best practices for professional applications? How do we know what sloppy code looks like, and how do we avoid creating sloppy code? Are there any best practices regarding the design of Winforms applications?

• A good way in .NET Winforms to have user entered time frame?

  - by Ben

  Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

• Any picture Gallery Control for .NET 1.1 in WinForms?

  - by Romias

  I need a UserControl to display pictures as a Gallery in Winforms. I have my pictures as a Image Collection but no problem to change to fit Control capabilities. It could be nice if it is for .NET 1.1 but since I'm planning to migrate all our code to 2.0 if the control is in that framework it could be useful in the future If it is free much better :) Does any of you know a control like this? Thanks!

• How can you speed up the display of WinForms in C#?

  - by Craig Johnston

  How can you speed up the display of WinForms in C#?

Other languages seem to be render forms a lot quicker. Is there a way to speed things up? Using C# in VS2005.
