问题 So I've got a "daily dashboard" report in SSRS 2005. It has a parameter, @pDate, which defaults to "=Now". I'd like to use this same report in a linked report to show yesterday's final dashboard (which would then be mailed out via subscription), and override the parameter default with another expression, "=dateadd(d,-1,Now)." But when I change the default parameter, I get a data mismatch error (natch). I'm assuming that's the end of the line and I just need to deploy a copy of the daily

问题 Following the C++ enum pattern I already described here, I was trying to do a similar thing but this time the sequence of values I want to use is not comprehended of continuous integer numbers. The code is obviously wrong: class Rotations { enum PossibleIndexes { ZERO, PLUS180, PLUS90, MINUS90 }; enum PossibleValues { ZERO= 0, PLUS180= 180, PLUS90= 90, MINUS90= -90 }; static int Count() { return MINUS90 + 1; } static PossibleValues Default(){ return ZERO; } }; as there will be conflicts

问题 Using Visual C# 2008 express edition, I am trying to create a button on my form to set the form back to default properties, such as size, backcolor, etc... anybody have any examples on how I would do this? 回答1: By far the simplest way is to just create a new instance of the form and close the old one. That requires a little bit of surgery if this is the main form of your app, closing it would terminate the program. Start by opening Program.cs and edit it so it looks like this: static class

问题 I've found myself using the following pattern as a way to get optional parameters with defaults in Go struct constructors: package main import ( "fmt" ) type Object struct { Type int Name string } func NewObject(obj *Object) *Object { if obj == nil { obj = &Object{} } // Type has a default of 1 if obj.Type == 0 { obj.Type = 1 } return obj } func main() { // create object with Name="foo" and Type=1 obj1 := NewObject(&Object{Name: "foo"}) fmt.Println(obj1) // create object with Name="" and Type

问题 I have an application that plays video files. I have been using code for using Videoview and starting the Videoview manually to play video files. However, I just wanted to know if I can use the default media player or video player of android rather than creating or using the VideoView to play the file..

问题 I have my templated container class that looks like this: template< class KeyType, class ValueType, class KeyCompareFunctor = AnObnoxiouslyLongSequenceOfCharacters<KeyType>, class ValueCompareFunctor = AnObnoxiouslyLongSequenceOfCharacters<ValueType> > class MyClass { [...] } Which means that when I instantiate an object of this class, I can do it several different ways: MyClass<MyKeyType, MyValueType> myObject; MyClass<MyKeyType, MyValueType, MyCustomKeyCompareFunctor> myObject; MyClass

问题 I am using a MySQL database with PHP. I store my date values in the database using the DATETIME field. I'm using this PHP code to convert inputted dates to the appropriate format for MySQL. date("Y-m-d H:i:s", strtotime($inputDate)) However, whenever a date is invalid, it is placed in the database as 1969-12-31 19:00:00 Is there a way to default this to 0000-00-00 00:00:00 ? 回答1: Just detect validity with the output of strtotime() , which returns false on failure. Something like: $time =
