Finish off with TRIM and an IFERROR 'wrapper'. In B1 as,

问题 I can't figure out why I'm getting the error library.mak:95: *** missing separator. Stop. When I use make on cygwin.

Separator in ItemsControl renders in different shades for each item

阅读更多关于 Separator in ItemsControl renders in different shades for each item

I have an ItemsControl presenting TextBlocks, with a Separator at the bottom of each item. My problem is that each Separator is rendered in a slightly different shade of gray - it looks really dodgy: Here is my XAML: <ItemsControl ItemsSource="{Binding Path=Items}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel></StackPanel> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding}" ></TextBlock> <Separator></Separator> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I have also

How to add menu items separators which work as expected on OSX?

阅读更多关于 How to add menu items separators which work as expected on OSX?

On Windows platform, with the VCL , when we want to add a separator in a menu, we add a TMenuItem with a Caption := '-' ; With FireMonkey , we add a TMenuItem with a Text := '-' ; It works as expected on Windows platform, the item with the Text='-' is displayed as a separator. But, when I run the same application on OSX , I have the minus sign visible... I haven't found any property on the TMenuItem to specify it is a separator ... I have tried with a TMainMenu and a TMenuBar ( UseOSMenu := True|False; ) and I still have this issue. Any idea to create a real separator? (otherwise, I will check

Hiding UITableView separator behind the contentView

阅读更多关于 Hiding UITableView separator behind the contentView

问题 I made a grouped UITableView in iPhone OS 3.0 that looked like the left image. The result is the right image in OS 3.1. The imageView is under the separators. I've tried to put the content view in front. The separatorStyle propriety seems ignored when the tableView is in grouped style (to draw the separator myself). Changing the separator color gives strings results. Thanks for your help! Edit: This is the code with no change made : static NSString *CellIdentifier = @"Cell"; UITableViewCell

I'd try (a) first ;) I did it with a custom view button, with a 1 pixel wide background: UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 1, 44)]; label.backgroundColor = [UIColor whiteColor]; UIBarButtonItem *divider = [[UIBarButtonItem alloc] initWithCustomView:label]; // Add button to array of toolbar items [items

Java CSV parser with string separator (multi-character)

阅读更多关于 Java CSV parser with string separator (multi-character)

Is there any Java open source library that supports multi-character (i.e., String with length > 1) separators (delimiters) for CSV? By definition, CSV = Comma-Separated Values data with a single character (',') as the delimiter. However, many other single-character alternatives exist (e.g., tab), making CSV to stand for "Character-Separated Values" data (essentially, DSV: Delimiter-Separated Values data). Main Java open source libraries for CSV (e.g., OpenCSV ) support virtually any character as the delimiter, but not string (multi-character) delimiters. So, for data separated with strings

Vertical bar (|) Unicode replacement

阅读更多关于 Vertical bar (|) Unicode replacement

问题 We are using the vertical bar | ( | ) character as a field separator in one of our modules. so the users should not use this character in a title. If they do use it, I would like to replace it with a similar character. Is there a Unicode replacement for it? The only character that I have found and looks similar to it is broken vertical bar ¦ ( ¦ ). 回答1: I do not understand what you really need. Do you need to change the separator sequence to something guaranteed not to exist in the dataset?
