问题 I know that in Visual Basic, delegate function cannot contain optional parameters. But can a method take a delegate as an optional parameter? What I want to do is this: Delegate Sub MyDelegate(ByVal input As String) Sub MyDelegateDefault(ByVal input As String) 'by default do nothing' End Sub Sub MyDelegateCustom1(ByVal input As String) 'do something here' End Sub In a different part of code: Sub OtherFunction(ByVal str As String, Optional ByVal delegate As MyDelegate = AddressOf

问题 I have a string like: $description = ' <a href="http://www.replace.com/1st-link/">1st link in string</a>, <a href="http://www.ignore.com/">2nd link in string</a>, some other text in string, <a href="http://www.replace.com/3rd-link/">3rd link in string</a>. '; I need to use preg_replace to append a query parameter of "?id=awesome" to any urls in the $description string from "replace.com" (ignoring all other links, i.e. "ignore.com"). Thanks in advance for any help! 回答1: Ok, simple enough, here

问题 I have a SQL query, mad in Python using Psycopg2. The query reads some columns from the arches table: rows = archesDB.read_all("""SELECT "+str(columns)[1:-1].replace("'","")+" FROM arches WHERE lower(arch) like '%%%s%%'""" % (arch.lower())) I want to parametrize this query, so that it will not specify the columns needed using string concatenation, but as parameters - a far more elegant way. The naïve way is to SELECT * , and filter out the columns I need. But this burdens the DB and network

问题 I have this jqgrid definition and I'm trying to open the selected document in a new Window. My final urls should like these: http://localhost/XPagesSortableSearchResults.nsf/xPerson.xsp?documentId=9D93E80306A7AA88802572580072717A&action=openDocument and also I need to generate this type of url: http://localhost/XPagesSortableSearchResults.nsf/$$OpenDominoDocument.xsp?documentId=9D93E80306A7AA88802572580072717&action=openDocument $().ready(function(){ jQuery("#list2").jqGrid({ url:'./xGrid7

问题 I have a report that has multiple cascading parameters, which works quite well out of Report Manager. I would like to create a version that will take a single parameter, and iterate over every parameter down the line. As an example, suppose parameters such as state, county and city. If we pass in a state (ie Florida) the report would have multiple pages for each county, each page consisting of one city in that county. The object is to email monthly reports to stakeholders in each state, with

问题 Basically, I want to know why this (passing the memory adress of list as parameter): void init_lista (elemPtr *list) { *list = NULL; } int main(){ elemPtr list; init_list(&list); //[...] } is different than this (passing just the content of list): void init_lista (elemPtr list) { list = NULL; } int main(){ elemPtr list; init_list(list); //[...] } OBS: elemPtr is a pointer type of a structure ( typedef struct elem *elemPtr ). What I understand from & and * is that the first will get the var's

问题 I'm looking to implement a RESTful API and I was wondering what parameter is advised when the browser client can't do a PUT/DELETE request to the server. (since some browser apparently doesn't support these requests) Does it exist a specific parameter name for that? (something like request_method=DELETE on a POST request, that should indicate to the server that the client really want a DELETE but can't indicate it)? or there is no specifications like that? My searches lead me to the

问题 I am using EasyGUI as part of a small program I am writing. In it, I am using the IntegerBox "function". Part of the parameters of this function is the lowerbound and the upperbound (the limits of the value entered). If the value is under the lowerbound or if it exceeds the upperbound, the program raises an error. Only for this program, I want to remove the lowerbound/upperbound--- so it is possible to put any number in. My code is: import easygui as eg numMin=eg.integerbox(msg="What is the

问题 Is there a way (in MySQL) to get the pure SQL statement after parameters have been added? I'm having issues with one of my statements once I start using parameters, and I want to see what's being executed. Of course it has to do with dates. Using MySQL .NET Connector. I have access to MySQL server, and I use SQLYog to administrate. Thanks! -Steve 回答1: You can use the query logs option to have all queries issued to the server logged.
