Hi, I need to create a stored procedure which receives a parameter (named @codes). This is a string which contains a list of codes separated by a semicolumn. I'd need to look inside a table and return all rows that have a code (which is in the column EANcodes) which was passed in the @codes parameter. Can anyone help me get started. M...
Okay, first off, I'm new to Silverlight and am looking for someone to provide guidance as to whether the following solution is the prescribed way of going about this. Yesterday I started working on a problem that, at first blush, seemed pretty simple and straightforward. I need to pass a few parameters from an ASPX code-behind, which ho...
I have a template class with a private map member template <typename T> class MyClass { public: MyClass(){} private: std::map<T,T> myMap; } I would like to create a private method that accepts an iterator to the map void MyFunction(std::map<T,T>::iterator &myIter){....} However, this gets a compile error: identifier 'iterat...

This was quite interesting and after a simple search with google, i found the results related to perl and Ruby but no result with PHP. Is it possible to pass parame...
While browsing some source code I came across a function like this: void someFunction(char someArray[static 100]) { // do something cool here } With some experimentation it appears other qualifiers may appear there too: void someFunction(char someArray[const]) { // do something cool here } It appears that qualifiers are onl...

I have the following models: Employee = (id, employeeName) Project = (id, projectName) Assignment = (fk_employee, fk_project, from_date, to_date) What I want to do is to create a validator that won't allow assignment periods to overl...

Possible Duplicate: Passing By ref and out C#: does using ref/out for a method parameter make any difference if an object variable is being passed? In C#, an object variable passes only a reference to the method, which means it is already a ref/out parameter. Is this correct? ...
My query in HQL is basically: select functionA(a, :paramA), functionB(b, :paramB), functionC(c, :paramC), sum(d) from tableA groupby by functionA(a, :paramA), functionB(b, :paramB), functionC(c, :paramC) However this gets turned into SQL of select functionA(a, @param0), functionB(b, @param1), functionC(c, @param2), sum(d) from table...
Hi, what, if at all possible, would be a good solution to implement the following desired functionality where I want to: Cast the return type of a routine to the type of the routine parameter, e.g., // Foo and Bar are two types of Common interface Common{} interface Foo extends Common {} interface Bar extends Common {} // Examp...
I assume not, but I just wanted to check - is there any way in C++ to do something like the following? Obviously when I try the below I get a scope-based error about bar. void foo(Bar bar, int test = bar.testInt) { ... } ...
Hi, I have thread spawning function which accepts many parameters which have default values in the declaration. int spawn( funcptr func, void *arg = 0,int grp_id = 1,const char*threadname); I want to initialize first parameter func and the last parameter thread name and remaining variables assigned their default values. spawn( myfunc...
Currently my code looks like this. It allows me to parse multiple parameters my program script gets. Is there a different way that is closer to 'best practices'? I haven't seen code actually using the output of argparse, only how to set it up. def useArguments(): x = 0 while x <= 5: if x == 0: ...

I have a lot of memory allocations and the same number of FreeMem calls. What I didn't have though is a check before calling freemem to see if the pointer was nil, and a line after freeing to set the pointer to nil. I tried to create a function to do this procedure FreeMemAndNil(p: Pointer; size: Integer = -1); begin if p <> nil t...
I have a set of commands that I'd like to run and do some returncode checks against the result, so i figured it would be easy to put them into an array for execution. Let's take this one as an example: C:\windows\system32\inetsrv\AppCmd.exe set config "Default Web Site/" /section system.webServer/webdav/authoring /enabled:true /commit:...
Hi, I have C# webservice webmethods hosted on a server and accessed by different applications(web,winforms etc).

All they do is adding a web reference and passing parameters, i wish to see in my end what parameters t...
