问题 I'm writing a simple asp page to show a team rota based on some XML. Here's the XML: <rota> <shift date="20091201" primary="Chan" secondary="John" notes="notes"></shift> <shift date="20091202" primary="Mike" secondary="Alex" notes="notes"></shift> <shift date="20091203" primary="Ross" secondary="Mike" notes="notes"></shift> <shift date="20091204" primary="Neil" secondary="Ross" notes="notes"></shift> </rota> I want my asp page to show today's rota details and maybe the details for the next

问题 I'm having a really hard time believing this question has never been asked before, it MUST be! I'm working on a batch file that needs to run some sql commands. All tutorials explaining this DO NOT WORK (referring to this link:Pass parameters to sql script that someone will undoubtedly mention)! I've tried other posts on this site verbatim and still nothing is working. The way I see it, there are two ways I can approach this: 1. Either figure out how to call my basic MYSQL script and specify a

问题 So, I have this templatized function (which I know is ugly to look at.) My intention was not to default the template parameter though, my intention was to create a typename derived from T that could be used in caster that the user could not assign to. My question is how do I create a typename for a templatized function which the user cannot pass as an argument? As an example: template <typename T> typename R = std::conditional<sizeof(T) == 4, char, short>; R foo(T bar){return R(bar);} Clearly

问题 Hey everyone, today I'm trying to get a link to an XML file passed from the Object Embed code into my Flash movie. (Not using SWFobject). I have 1 swf file that should be able to connect to 3 different XML files. Attempt 1 Below is the HTML code (I'm trying to get theXML path): <div class="left"> <h2>300 x 353 Green Accent Color</h2> <script type="text/javascript"> AC_FL_RunContent( 'codebase','http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0','width','300'

问题 I have an XML on which I am displaying the test cases as HTML using XSLT. I have one query. How to pass a variable as a parameter and access it on the other page. So far I achieved this: <xsl:for-each select="//test-suite[@type='TestFixture']"> <tr> <xsl:choose> <xsl:when test="contains(@result, 'Success')"> <xsl:variable name="nameOfPage" select="@name" /> <td><a href="DownloadManagerFeature.xml?nameOfPage={$nameOfPage}" style="text-decoration: none" ><font color="239625"><xsl:value-of

问题 Lets say my file looks like this: #include <iostream> #include <string> using namespace std; class testclass{ public: string name; //testclass(const string& sref){ // name = sref; //} testclass(string str){ name = str; } ~testclass(){} }; int main(){ testclass t1("constStringRef"); cout << t1.name << '\n'; } What are the differences between constructor 1 and 2 given the following constructor-call: testclass tobj("tmemberstring"); Here is what i thought of: I know that passing by reference

问题 I have a function that takes in a number of parameters.. it then does a db insert. i have a foreign key on one of the fields (modelID) i want to pass a NULL if no model ID is selected. i tried the following: Dim model As Nullable(Of Integer) If ddlModel.SelectedValue = "Other" Then 'add new model model = cSource.InsertModel(txtModel.Text, ddlManuf.SelectedValue) ElseIf ddlModel.SelectedValue = "0" Then model = Nothing Else model = ddlModel.SelectedValue End If but now i get an error saying:

问题 I'm new to the Django Framework and one thing bothers me. I want a simple Rest Call: www.abc.com/users/1/cantonments/1/ If i use 'pk' in the url pattern everything works out of the box (pk, pk1, pk2....). But i have some permission functionality which expects the parameters in kwargs in the form 'upk' and 'cpk' for user and cantonment. So if i change pk to upk everything breaks. Somehow the url needs ONE pk. This works: url(r'^users/(?P<pk>[0-9]+)/cantonments/(?P<cpk>[0-9]+)/$', views

问题 Code below taken from here. * qsort example */ #include <stdio.h> #include <stdlib.h> int values[] = { 40, 10, 100, 90, 20, 25 }; int compare (const void * a, const void * b) { return ( *(int*)a - *(int*)b ); } int main () { int n; qsort (values, 6, sizeof(int), compare); for (n=0; n<6; n++) printf ("%d ",values[n]); return 0; } We have a compare function with parameters in its signature but when we call it in qsort no arguments are passed. How are the values of a and b passed to the function

问题 When I use the code <%= render 'chart', width:100 %> I can get the width value in the page, like <%= width %> But if I want to get the width value in java script in the same page, I really have no idea. So my pending solution is hiding the value in the div, then use the $('div').text() to retrieve the value. So I just want to know if we have any other way to get the parameters passed in rails by java script? 回答1: You can directly output the value in the javascript part: <script type="text
