converter

问题 I have a DataGrid with several Columns. Some of these columns are something like state|Color1|Color2|Color3|... I want to do this: If state==1 => RowForeground = Color1 If state==2 => RowForeground = Color2 If state==3 => RowForeground = Color3 ... The very first solution I can think is to use several Data Triggers: <DataTrigger Binding="{Binding Path=state}" Value="0"> <Setter Property="Foreground" Value="{Binding Path=color0, Converter={StaticResource str2clrConverter}}"/> </DataTrigger>

问题 I am wondering if someone could help me how to make connections between measures, for example how can I calculate relation between centimeters and inches like in the picture. This is my app for school project and it is more or less done except that part. So i am reading values from plist, and based on my first column in picker, second and third are displayed. All units and measures are read from plist. With energy, distance, volume etc. as keys. So what would be easiest way to make

问题 Is it possible to override the default converter of JSF with a custom converter. For instance what will happen if I register a custom converter with CONVERTER_ID="javax.faces.Enum" in faces-config.xml. Would JSF pick custom converter or would it still use the in-built EnumConverter? Kaushal 回答1: You can define your custom converter and use it in JSF components that you would like to override the default one: http://www.mkyong.com/jsf2/custom-converter-in-jsf-2-0/ If you want to definitely use

问题 I'm using SQL Server 2005. The datatype is varchar . I'm trying to convert numbers like 1250000 to 1.25 within the SQL query and drop the trailing zeroes. I have tried a number of things with no success - have run into 'trim is not a function', etc. Here's what I currently have, in each iteration that I have attempted. select top 30 var1, var2, var3, var4, CONVERT(DECIMAL(6,2), (var5 / 1000000)) as 'Number' from databasetable where var1 = x select top 30 var1, var2, var3, var4, cast((var5 /

问题 I wrote my first JSF (1.2) custom converter. I declared it in faces-config.xml ( converter-id and converter-class ), wrote the Java class implementing getAsObject and getAsString methods. Then i put the converter in a page like this: <ice:selectInputDate id="ctldatanascita" value="#{beanrichiestaabilitazione.datanascita}" renderAsPopup="true"> <f:converter converterId="cisConverterDate" /> </ice:selectInputDate> The class is istantiated, but the Converter interface methods are never called.

问题 How do I take a single ASCII character and convert it to its decimal equivelant in MIPs? Do I simply have to have some conditions to subtract a certain amount from the ascii code to make it its decimal representation? 回答1: Here's a simplistic implementation of what Pax wrote (it assumes that hexadecimal digits - A to F are always upper case) File hextodec.c #include <stdio.h> /* *Converts an ASCII char to its decimal equivalent. *Returns -1 on error. * */ extern int hextodec(char* c); int

问题 I'm stuck at the situation when the type of an object was changed. How can I convert this: { "_id" : NumberLong(257), "address" : "street Street, house 50, appartment 508, floor 5" } to this: { "_id" : NumberLong(257), "userAddressList" : [{ "street" : "Street", "house" : "50", "building" : "", "appartment " : NumberLong(508), "entrance" : NumberLong(0), "floor" : NumberLong(5), "intercom" : "" }] } using mongo shell? I need to convert about 350 entries, hope it can be done by the script. 回答1

问题 I have an array of data (in reality a parsed CSV dump from MySQL with headers) ['adam', 'smith', 'honda', 'civic'] I have an object which defines how that array of data should look as an object. { first_name : 0, last_name: 1, car : { make: 2, model: 3 } } This object could have any depth of nested values. It is also dynamically generated. My question is: how do I cast the values from the array to the object? (I am trying to make a recursive function loop over the object and grab the array
