  • Generating Color Gradient

    - by Malfist
    I want to display to my user how many (percent wise) of their forms are compliant with the new standard. The way I want to let them know visually is the percent amount will be colored. It will be 0xFF0000 (pure red) for 0% and 0x00FF00 (pure green) at 100%. What is the best way to calculate the color for each step along the way?

  • Taking over someone else's code

    - by tom d
    I am taking over someone elses code. What are some good ways to learn what that programmer did as quickly as possible? I have been running it, stepping through it and looking at the callstack. What else can I do? Sorry I forgot to mention, but there is little documentation and I have been trying to fix simple problems. Thanks!

  • Restore WindowState from Minimized

    - by tbetts42
    Is there an easy method to restore a minimized form to its previous state, either Normal or Maximized? I'm expecting the same functionality as clicking the taskbar (or right-clicking and choosing restore). So far, I have this, but if the form was previously maximized, it still comes back as a normal window. if (docView.WindowState == FormWindowState.Minimized) docView.WindowState = FormWindowState.Normal; Do I have to handle the state change in the form to remember the previous state?

  • How to handle the close (big X) button at the source?

    - by Simon T.
    We would like under some circumstances to block the action of the close button in the title bar. The problem is that it's a MDI applications and it seems that we will have to add code in each forms to cancel the operation in the Closingevent handler. It seems that the child forms are the first to receive the event. There is no way to add code at a single place to cancel the close operation. Information on how the close event is propagated to the child form would be welcome. Is there a simple way of doing what we want to do?

  • How can I keep up to date on the latest web development standards?

    - by Structure
    First off, I know that this question begs the other question - should the latest web development standards be followed and further will they remain relevant? That aside, I am focused on GUI development, usability, etc. Front-end web development that utilizes XHTML, CSS, JavaScript, etc. I know there are many gurus and thought leaders out there but with my projects I simply do not always have time to follow them all and keep up with the latest development standards. However, this is obviously very important. So how can I keep myself up to date on the latest web development standards while maintaining productivity? Are there any specific groups or organizations to monitor for this? Best practices that one might follow?

  • Format TimeSpan in DataGridView column

    - by Dan Neely
    I've seen these questions but both involve methods that aren't available in the CellStyle Format value. I only want to show the hours and minutes portion (16:05); not the seconds as well (16:05:13). I tried forcing the seconds value to zero but still got something like 16:05:00. Short of using a kludge like providing a string or a DateTime (and only showing the hour/minutes part) is there any way I can get the formatting to do what I want.

  • Is there a way to organize a icon collection to allow for easy searching?

    - by John M
    Is there any way of organizing a icon collection so that it easier to find needed icons? For example: the program needs a save icon there are 5 icons collections on your HD that have a save icon and there are 5 more collections that don't have a save icon (but you don't know that) do you browse through each icon collection? run a search (assumes files are named consistently)? Would it be ideal to have some sort of organized directory (printable?)?

  • Is there any way to disable the "double-click to copy" functionality of a .NET label?

    - by DavidCarroll
    This is really annoying. I'm using the label as part of a list item user control, where the user can click it to select the list item and double-click it to rename it. However, if you had a name in the clipboard, double-clicking the label will replace it with the text of the label! I've also check the other labels in the application, and they will also copy to the clipboard on a doubleclick. I have not written any clipboard code in this program, and I am using the standard .NET labels. Is there any way to disable this functionality?

  • For which substring of the string1 matches occurred with the string2.

    - by Harikrishna
    I want to know that in particular string1 for which substring of the string1 the string2 matches.Like String str1="Order Number Order Time Trade Number"; String str2="Order Tm"; string regex = Regex.Escape(str2.Replace(@"\ ", @"\s*"); bool isColumnNameMatched = Regex.IsMatch(str1, regex, RegexOptions.IgnoreCase); I am using regex because "Order Tm" will also matches "Order Time".It gives bool value that matches occurred or not. But if it str2 is in str1 then I want to know at which position in the str1 the str2 matches. Like str2="Order Tm" then something like that returns the string which is matched with str2 in the str1.Here str2="Order Tm" then it should return like in the str1,Order Time is the substring where matches is occurred.

  • In a Windows forms application, how can I use a listbox in a DataGridView coloumn instead of a combo

    - by Alex
    I'm working on a windows forms application that uses a DataGridView. Some of the cells contain a DataGridViewComboBox. In some cases, I have several values to display in the combobox. For that scenario, it would be better to use a ListBox instead of a ComboBox. Is it possible to use a multi-column listbox within a DataGridView instead of a ComboBox? If so, can you point me in the right direction? Thanks much. Al D.

  • How do you get the solution directory in C# (VS 2008) in code?

    - by IsaacB
    Hi, Got an annoying problem here. I've got an NHibernate/Forms application I'm working through SVN. I made some of my own controls, but when I drag and drop those (or view some form editors where I have already dragged and dropped) onto some of my other controls, Visual studio decides it needs to execute some of the code I wrote, including the part that looks for hibernate.cfg.xml. I have no idea why this is, but (sometimes!) when it executes the code during my form load or drag and drop it switches the current directory to C:\program files\vs 9.0\common7\ide, and then nhibernate throws an exception that it can't find hibernate.cfg.xml, because I'm searching for that in a relative path. Now, I don't want to hard code the location of hibernate.cfg.xml, or just copy hibernate.cfg.xml to the ide directory (which will work). I want a solution that gets the solutions directory while the current directory is common7\ide. Something that will let someone view my forms in the designer on a fresh checkout to an arbitrary directory on an arbitrary machine. And no, I'm not about to load the controls in code. I have so many controls within controls that it is a nightmare to line everything up without it. I tried a pre build event that made a file that has the solution directory in it, but of course how can I find that from common7\ide? All the projects files need to be in the solution directory because of svn. Thanks for your help guys, I've already spent a few hours fiddling with this in vain.

  • Does Adding more namespace in the code file affect performace ?

    - by Harikrishna
    If we imports more namespace in the code file(cs file) then it affects on perfomance ? Like we should add namespace in the cs file as needed. That is adding more namespace in the cs file affects performance ? Like using System; using System.Data.Sql; using System.Collections.Generic; using System.Data; using System.IO; using System.Linq; using System.Text.RegularExpressions; using System.Windows.Forms; using System.Xml; using System.Data.SqlClient; using System.ComponentModel;

  • Exception in the OnIdle event does not bubble up

    - by sthay
    On my main form, I subscribed to two events: Application.ThreadException and Application.Idle. In theory, any exception that is not caught should get bubbled up to the main form. However, this does not work if the exception happens in the OnIdle event. The system just crashes. Does anyone know how to solve this problem? Thanks so much.

  • .NET grouping forms so that pulling up the primary form shows all other forms?

    - by toasteroven
    I have an app that can open up some other forms at the user's request, and they're set to not show in the taskbar. The problem is, if one of the secondary windows becomes hidden by another app, switching to the primary window only brings that form to the forefront. Is there a good way to "group" the forms so that giving any of them focus brings the whole group to the front? I tried calling BringToFront() on each form in the primary form's Activated event, but that also gives the secondary forms focus, making it impossible to interact with the primary form.
