  • Excel Matching problem with logic expression

    - by abelenky
    I have a block of data that represents the steps in a process and the possible errors: ProcessStep Status FeesPaid OK FormRecvd OK RoleAssigned OK CheckedIn Not Checked In. ReadyToStart Not Ready for Start I want to find the first Status that is not "OK". I have attempted this: =Match("<>""OK""", StatusRange, 0) which is supposed to return the index of the first element in the range that is NOT-EQUAL (<) to "OK" But this doesn't work, instead returning #N/A. I expect it to return 4 (index #4, in a 1-based index, representing that CheckedIn is the first non-OK element) Any ideas how to do this?

  • Regular expression in mySQL [migrated]

    - by Rayne
    I have a mysql table that has 2 columns - Column 1 contains a string value, and Column 2 contains the number of times that string value occurred. I'm trying to find the string abc.X.def, where the beginning of the string is "abc.", followed by one or more characters, then the string ".def". There could be more characters following ".def". How can I find such strings, then add the occurrence of such strings and display the results? For example, if I have abc.111.def23 1 abc.111.def 2 abc.22.def444 1 abc.111.def 1 Then I will get abc.111.def23 1 abc.111.def 3 abc.22.def444 1 Thank you.

  • How do I use Sketchflow sample data for a ListBoxItem Template at design time?

    - by Boris Nikolaevich
    I am using Expression Blend 4 and Visual Studio 2010 to create a Sketchflow prototype. I have a Sample Data collection and a ListBox that is bound to it. This displays as I would expect both at design time and at run time. However, the ListBoxItem template it just complex enough that I wanted to pull it out into its own XAML file. Even though the items still render as expected in the main ListBox where the template is used, when I open the template itself, all of the databound controls are empty. If I add a DataContext to the template, I can see and work with the populated objects while in the template, but then that local DataContext overrides the DataContext set on the listbox. A bit of code will illustrate. Start by creating a Sketchflow project (I am using Silverlight, but it should work the same for WPF), then add a project data source called SampleDataSource. Add a collection called ListData, with a single String property called Title. Here is the (scaled down) code for the main Sketchflow screen, which we'll call Main.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:DemoScreens" mc:Ignorable="d" x:Class="DemoScreens.Main" Width="800" Height="600"> <UserControl.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="ProjectDataSources.xaml"/> </ResourceDictionary.MergedDictionaries> <DataTemplate x:Key="ListBoxItemTemplate"> <local:DemoListBoxItemTemplate d:IsPrototypingComposition="True" Margin="0,0,5,0" Width="748"/> </DataTemplate> </ResourceDictionary> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="#5c87b2" DataContext="{Binding Source={StaticResource SampleDataSource}}"> <ListBox Background="White" x:Name="DemoList" Style="{StaticResource ListBox-Sketch}" Margin="20,100,20,20" ItemTemplate="{StaticResource ListBoxItemTemplate}" ItemsSource="{Binding ListData}" ScrollViewer.HorizontalScrollBarVisibility="Disabled"/> </Grid> </UserControl> You can see that it references the DemoListBoxItemTemplate, which is defined in its own DemoListBoxItemTemplate.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:DemoScreens" mc:Ignorable="d" x:Class="DemoScreens.DemoListBoxItemTemplate"> <Grid x:Name="LayoutRoot"> <TextBlock Text="{Binding Title}" Style="{StaticResource BasicTextBlock-Sketch}" Width="150"/> </Grid> </UserControl> Obviously, this is way simpler than my actual listbox, but it should be enough to illustrate my problem. When you open Main.xaml in the Expression designer, the list box is populated with sample data. But when you open DemoListBoxItemTemplate.xaml, there is no data context and therefore no data to display—which makes it more difficult to identify controls visually. How can I have sample data displayed when I am working with the template, while still allowing the larger set of sample data to be used for the ListBox itself?

  • How to evaluate a custom math expression in Python

    - by taynaron
    I'm writing a custom dice rolling parser (snicker if you must) in python. Basically, I want to use standard math evaluation but add the 'd' operator: #xdy sum = 0 for each in range(x): sum += randInt(1, y) return sum So that, for example, 1d6+2d6+2d6-72+4d100 = (5)+(1+1)+(6+2)-72+(5+39+38+59) = 84 I was using regex to replace all 'd's with the sum and then using eval, but my regex fell apart when dealing with parentheses on either side. Is there a faster way to go about this than implementing my own recursive parsing? Perhaps adding an operator to eval?

  • Passing expression as a parameter in Call by reference

    - by darkie15
    All, When we are passing an expression as a parameter, how does the evaluation occur? Here is a small example. This is just a pseudocode kind of example: f (x,y) { y = y+1; x = x+y; } main() { a = 2; b = 2; f(a+b, a) print a; } When accessing variable x in f, does it access the address of the temp variable which contains the result of a+b or will it access the individual addresses of a and b and then evaluate the value of a+b Please help. Regards, darkie15

  • Expression parser library for Android.

    - by Malx
    What is the best way to evaluate simple conditional statements like: "a>b" ? "x-4<10+y & y>x" ? Expressions are loaded from external file. Variables are set in application. Syntax used is not essential. It may be "&" or "and" or any other supported with language/library. I need to take different action depending on result of evaluation - is it true or false. Could I use any parser already included with Andorid? Is there some way to use JS "eval" from browser component? Is it possible to use sqlite expressions to get true/false result without selecting anything? Those libraries are implemented in native code. Will it be faster and less battery expensive?

  • Application Screen Repainting Issues

    - by Jeff Sheldon
    I have this issue lately at work. It drives be nuts, and I finally stopped to ask this question. It's quite often that an application I've been running just randomly fails to repaint itself for a while, usually in the editor screen. I most often see this occurring with Expression Web, Visual Studio 2008/2010 and SQL Server Management studio. These applications are what I work in the most, so I'm not surprised to mostly see it here. But I was curious if anyone else had a solution for this. I've tried: Reboots. The screen shot below is about 10 minutes after a reboot. New Video Drivers. This machine is running a Nvidia Quadro NVS 290 video card with the latest drivers. Closing other applications, this is the only thing running right now. As far as hardware, this machine has Dual Quad-Core Xeon 2.83ghz Processors, with 10 gigs of memory, running Windows XP SP3 64bit. Any help would be great. JNK EDIT: Per comments from deleted (wrong) answer: I'm running dual monitors. Set it to single display, still occurred. Rebooted, and tried it again, and it still occurred. Switched it back to dual screen. My resolution is only 1400x900 on each.

  • How can I get objects and property values from expression trees?

    This is a follow-up to the Getting Information About Objects, Types, and Members with Expression Trees post, so I would recommend that you read that one first. Among other code examples in that blog post, I demonstrated how you can get a property name as a string by using expression trees. Here is the method. public static string GetName<T>(Expression<Func<T>> e) { var member = (MemberExpression)e.Body; return member.Member.Name; } And here is how you can use it. string...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Complex(?) regex: Is expression, but not another

    - by Kieron
    (If you can make a better title, please do) Hi, I need to make sure a string matches the following regex: ^[0-9a-zA-Z]{1}[0-9a-zA-Z\.\-_]*$ (Starts with a letter or number, then any number of letters, numbers, dots, dashes or underscores) But given that, I need to make sure it doesn't match a Guid, my Guid matching reg-ex looks like this (obviously, this needs to be negated in the merged result): ^([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}$ The last requirement here is that they must (if it's possible) be merged into a single expression.
