Remove Filter  | I have a string representing a date time, and a datetime local variable property. The string representing the datetime could be null or an empty string.

| | I'm not sure if this is the right forum to ask this in, sorry if it isn't. It's been a while since I've been to this site. We have a MS SQL database that contains a table with some columns that are no longer used (or shouldn't be). The data …  |

| | Good afternoon everyone! I'm running into a small snag and it could just be because it's late and I'm not thinking clearly. I have an ASP Panel that is an alert box. The panel's initial visible property is set to false and should only be set to true when specific … |
| | If I implement an abstract class that contains this method: private void MyMethod(string awesomeParameter, int aBigNumber) { // something cool happens here! throw new NotImplementedException(); } can I change it to this without breaking the implementation? private void MyMethod(string myParam, int myInt) { // something cool happens here! throw new …  |

| | Forgive me, but I've only really used WinForms in the past, and MVVM and WPF are new to me. For those who use MVVM with WPF, do you actually make separate directories (namespaces) for your Models, Views and ViewModels files or is it more of an abstract idea? I fundamentally … |
| | I am starting a new application for our business to help maintain our client information, so it is going to be a very data driven application. I'm curious, from the standpoint of those who have used both and who may have constructive suggestions on the future direction of development, should … |

| | I know the site switched to a tag system, and while I personally don't care for it, I like the community too much to find an alternative. Since I really only post to a single "tag" group, is it possible for people to have a favorite tags list we can … |
| | Good afternoon fine DaniWeb folks! I am about to pull my hair out on this one and I'd like to know if someone knows of a simple or obvious "gotcha!" for this problem. I've got a form with some detail fields on it (below)  When a user attempts … |
| | I would like to see a forum dedicated to UX/UI design. I know that a good application or website performs its job exceptionally well and the look and feel of the application doesn't affect, or shouldn't affect it's performance. But come on! It does. UX/UI design is more than just … |
| | I am trying to programatically create and dispose of file system watchers, but I am running into an issue when trying to dispose of them. When I try to use the code: // dispose of any existing watchers. foreach (FileSystemWatcher fileWatcher in this.Controls) { fileWatcher.Dispose(); } I am receiving a … |
| | I'd like to suggest a forum category for Azure development. Many of the concepts are covered by the topics here, but some are not, such as Azure SQL Database, Virtual Machines and Virtual Networks, Cloud Services, etc... I know that some of those (VMs and VNs notibly) aren't really directly …  |
| | I'd like to propose that DaniWeb adds a new category of forums for Cloud development. The Software and Web Development might apply, but with the cloud being so versatile, you could technically do either Software or Web work on it. Just throwing that out there :) |
| | I'm sorry if this is the wrong place to put this, but since I normally code in C#, and my potential solution would involve using C# I figured this would be the best place to start. I've been given a task at work to allow our customers the ability to … |

| | Out of curiosity, when you start a new solution and you add your first project to it, if it's a window's form application, you get a nice and neat form called "Form1" (how creative!). Do you rename that file? If so, what do you name it? If not, why?  |
| | So I was playing around with Visual Studio 2010 and when I removed the Application.EnableVisualStyles() method from the Main() method, I noticed that the controls on the design surface don't change, they maintain their visual style, but when the application is run, it doesn't have the styles. Is there a … |

| | Hi everyone! I am working on a custom control, and for the life of me I can't figure this one out. As of right now, all properties for controls that are settable in the editor I use this code: [Browsable(true), Description(""), Category(""), DefaultValue()] I fill in the blanks appropriately, but … |
| | So I've been thinking about SQL security lately and wanted to see what others are doing. I have been using integrated security (window's authentication), stored procecedures when necessary and have done my best to limit access to tables and those stored procedures with SQL server in conjunction with my application. … |
| | I have a DataGridView that contains 3 columns, the first is a drop down and the second and third are textboxes. However, the third one is read-only and is only there to provide information to the user on the item selected from the dropdown column. If the user changes the … |

| | In order to show a first run dialog (a window that appears before the main application starts if certain conditions are met) I have decided to modify the Main method and do this: static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); if (Properties.Settings.Default.FirstRun) { Application.Run(new RunOnce()); } Application.Run(new Main()); } Is this … |

| | The application I am working on uses SQL to store data. Most of the data is fine the way it is, but one of the tables contains information that would be very tempting for some users to alter. My original plans were to have the application check the identity column … |
| | Just came across [this](http://www.faqs.org/rfcs/rfc2821.html) (RFC2821) and in section 4.5.3.1 (Size limits and minimums) it states (emphasis added): > There are several objects that have required minimum/maximum sizes[...] > **local-part** > *The maximum total length of a user name or other local-part is 64 characters.* > > **domain** > *The maximum … |

| | I need to retrieve the major and minor version of the application, and instead of instantiating a new Version class with `new Version(Application.ProductVersion);` is there a static copy of the Version class that already exists? If so, I can't find it, can someone point me in that direction, or is … |
| | I need an array for a method to use to iterate through a string's characters and perform certain operations when one is found or found in certain combinations. Anyway, to keep things separate and easier to interpret later, I have created an array of characters for the method to iterate … |
