parameters

问题 I have 5 parameters and I want to send them to the method: public static SqlCommand getCommand(string procedure, SqlParameter[] parameter) { Sqlcommand cmd; return cmd } Can I send these paramters at one time like this? SqlParameterCollection prm; prm.Add(p1); prm.Add(p2); prm.Add(p3); prm.Add(p4); prm.Add(p5); sqlcommand cmd = getCommand(prm); 回答1: Or create an array of parameters by hand: SqlParameter[] parameter = { new SqlParameter(...), new SqlParameter(...), new SqlParameter(...) }; But

问题 I created bool dropIndexes to void ladujZBazy and created if (dropIndexes) beacuse When I checked items on list in checkedListBox1 and search some items using textBox1 my previous check is gone.

问题 My Facebook feed dialog link correctly renders a dialog page, but the image set with the picture parameter does not show up -- just the gray line that indicates no picture. I've changed picture files and types a few times, but the image still doesn't show up. Here is the code: $share_url = "https://www.facebook.com/dialog/feed?app_id=$app_id"; $share_url .= "&link=http://www.doozeez.com"; $share_url .= "&picture=http://doozeez.com/images/halloweenloot.png"; $share_url .= "&caption=to spend in

问题 <script src="myscript.js?someParameter=123"></script> From within myscript.js , is there any way to obtain that someParameter was set to 123 ? Or is the only way to use server side scripts that generate the javascript file with the parameters in it? 回答1: Well, you get URL parameters from window.location.href . As the name says, it refers to the current window. What the <script> tag does it to embed the linked file into the current document, thus into the same window. If you parsed window

问题 The title is pretty self-explanatory, but here's a simplified example: #include <cstdio> template <typename T> struct MyTemplate { T member; void printMemberSize() { printf("%i\n", sizeof(T)); } }; int main() { MyTemplate<struct { int a; int b; }> t; // <-- compiler doesn't like this t.printMemberSize(); return 0; } The compiler complains when I try to use an anonymous struct as a template argument. What's the best way to achieve something like this without having to have a separate, named

问题 I would like to map this: http://www.example.com/index.php?param1=value1&param2=value2&param3=value3 (etc. ad infinitum) to http://www.example.com/index.php?param1=newvalue1&param2=value2&param3=value3 (etc.) In other words, just change the value of a single parameter in the query string. I know what the old value is, so I am trying to match the exact text index.php?param1=value1 and replace it with index.php?param1=newvalue1 . I cannot seem to find any examples on how to do this using mod

问题 Hello Android developers, I'm trying to pass arguments between two distinct activities but I've got stuck into an issue and I can't get out of it. Basically, I'm trying to pass two strings from a fragment contained in my MainActivity, MainFragment to my secondary activity, SecondaryActivity I can pass those two strings from Other Activities to the SecondaryActivity without issues.

问题 I can't figure out how the firstname and lastname variables are being set in the below C code. printf("Hello, %s, %s\n", firstname, lastname); It looks the char [s] parameter of the readln function is setting firstname & lastname. Is this possible, if so what is this called so I can do a bit of research. Thanks Edit: Below is a simpler version. It looks like the parameter is setting a variable. int foo(char s[]){ s[0]='w'; s[1]='\0'; return 5; } int main() { char name[2]; int wtf; wtf = foo
