  • SSIS with different table structures

    - by Grace
    I have a flat file source from Excel that has a structure like this: **People** Day1 Day2 Day3 Day4 Person1 someValue ... Person2 Person3 And i would like the package to put this information in a database with standard columns 'Person', 'Day', 'Value'. Does anybody know how to do this - at the moment because the days are going along the top, the package is assuming these are seperate data columns when they are not really and the mapping is not working.

  • Efficiently get the size of a parameter pack up to a certain index

    - by NmdMystery
    I want to be able to determine the number of bytes that are in a subset of a parameter pack from 0 to a given index. Right now I'm using a non-constexpr way of doing this. Below is my code: template <size_t index, typename... args> struct pack_size_index; template <size_t index, typename type_t, typename... args> struct pack_size_index <index, type_t, args...> { static const size_t index_v = index; static const size_t value(void) { if (index_v > 0) { return sizeof(type_t) + pack_size_index<index - 1, args...>::value(); } return 0; } }; template <size_t index> struct pack_size_index <index> { static const size_t index_v = index; static const size_t value(void) { return 0; } }; Usage: //output: 5 (equal to 1 + 4) std::cout << pack_size_index<2, bool, float, int, double>::value() << std::endl; //output: 20 (equal to 8 + 8 + 4) std::cout << pack_size_index<3, double, double, float, int>::value() << std::endl; This gets the job done, but this uses runtime comparison and the resulting executable increases in size rapidly whenever this is used. What's a less expensive way of doing this?

  • Translate an IQueryable instance to LINQ syntax in a string

    - by James Dunne
    I would like to find out if anyone has existing work surrounding formatting an IQueryable instance back into a LINQ C# syntax inside a string. It'd be a nice-to-have feature for an internal LINQ-to-SQL auditing framework I'm building. Once my framework gets the IQueryable instance from a data repository method, I'd like to output something like: This LINQ query: from ce in db.EiClassEnrollment join c in db.EiCourse on ce.CourseID equals c.CourseID join cl in db.EiClass on ce.ClassID equals cl.ClassID join t in db.EiTerm on ce.TermID equals t.TermID join st in db.EiStaff on cl.Instructor equals st.StaffID where (ce.StudentID == studentID) && (ce.TermID == termID) && (cl.Campus == campusID) select new { ce, cl, t, c, st }; Generates the following LINQ-to-SQL query: DECLARE @p0 int; DECLARE @p1 int; DECLARE @p2 int; SET @p0 = 777; SET @p1 = 778; SET @p2 = 779; SELECT [t0].[ClassEnrollmentID], ..., [t4].[Name] FROM [dbo].[ei_ClassEnrollment] AS [t0] INNER JOIN [dbo].[ei_Course] AS [t1] ON [t0].[CourseID] = [t1].[CourseID] INNER JOIN [dbo].[ei_Class] AS [t2] ON [t0].[ClassID] = [t2].[ClassID] INNER JOIN [dbo].[ei_Term] AS [t3] ON [t0].[TermID] = [t3].[TermID] INNER JOIN [dbo].[ei_Staff] AS [t4] ON [t2].[Instructor] = [t4].[StaffID] WHERE ([t0].[StudentID] = @p0) AND ([t0].[TermID] = @p1) AND ([t2].[Campus] = @p2) I already have the SQL output working as you can see. I just need to find a way to get the IQueryable to translate into a string representing its original LINQ syntax (with an acceptable translation loss). I'm not afraid of writing it myself, but I'd like to see if anyone else has done this first.

  • What's the easiest way to create an extensible custom container in Flex?

    - by Chris R
    I want to create an MXML container component that has some of its own chrome -- a standard query display, et al -- and that supports the addition of child components to it. Something a lot like the existing mx:Panel class, which includes a title label, but acts like a plain mx:Box with regards to adding children. What's the easiest way to do this? Edit: To be clear, I want to be able to extend the container using MXML, so the "Multiple visual children" problem is relevant.

    - by user1781595
    I am about building a bar for DWM (ubuntu linux), showing wifi details such as the ssid. Thats my code: #include <stdio.h> #include <stdlib.h> int main( int argc, char *argv[] ) { FILE *fp; int status; char path[1035]; /* Open the command for reading. */ fp = popen("iwconfig", "r"); if (fp == NULL) { printf("Failed to run command\n" ); exit; } char s[500]; /* Read the output a line at a time - output it. */ while (fgets(path, sizeof(path)-1, fp) != NULL) { sprintf(s,"%s%s",s, path); } //printf("%s",s); /* close */ pclose(fp); char delimiter[1] = "s"; char *ptr; ptr = strtok(s, delimiter); printf("SSID: %s\n", ptr); return 0; } i am getting overflowerrors and dont know what to do.

  • Is there an API available to retrieve raw Wiktionary Data?

    - by Armentage
    I want to build a simple application that looks up words against Wiktionary to see if they exist. Is there a standard API supported by the Wiktionary software that would let me do this? Alternatively, is there any way I can pull down the dictionary data that backs a Wiktionary? There are many international variants who's data I would love to put a different front-end around.

  • How to perform an action when a remote (Http) file changed?

    - by ZeissS
    Hi, I want to create a script that checks an URL and perform an action (download + unzip) when the "Last-Modified" header of the remote file changed. I thought about fetching the header with curl but then I have to store it somewhere for each file and perform a date comparison. Does anyone have a different idea using (mostly) standard unix tools? thanks

  • Is external JavaScript source available to scripting context inside HTML page?

    - by John K
    When an external JavaScript file is referenced, <script type="text/javascript" src="js/jquery-1.4.4.min.js"></script> is the JavaScript source (lines of code before interpretation) available from the DOM or window context in the current HTML page? I mean by using only standard JavaScript without any installed components or tools. I know tools like Firebug trace into external source but it's installed on the platform and likely has special ability outside the context of the browser sandbox.

    - by CycDemo
    If I use as below, I get no error, no output. Why does p:panelGrid not work with ui:repeat? Note : I don't want to use c:forEach because of the I already face a lot of JSF issue. <p:panelGrid> <ui:repeat value="#{MyBean.dataList}" var="data"> <p:row> <p:column> <h:outputText value="#{data.name}"/> </p:column> <p:column> <h:outputText value="#{data.description}"/> </p:column> </p:row> </ui:repeat> </p:panelGrid> MyBean.java public List<Data> getDataList(){ List<Data> result = new ArrayList<Data>(); result.add(new Data("Name 1", "Description 1")); result.add(new Data("Name 2", "Description 2")); result.add(new Data("Name 3", "Description 3")); result.add(new Data("Name 4", "Description 4")); return result; } Expected output with primefaces

  • PHP: Adding arrays together

    - by Svish
    Could someone help me explain this? I have two snippets of code, one works as I expect, but the other does not. This works $a = array('a' => 1, 'b' => 2); $b = array('c' => 3); $c = $a + $b; print_r($c); // Output Array ( [a] => 1 [b] => 2 [c] => 3 ) This does not $a = array('a', 'b'); $b = array('c'); $c = $a + $b; print_r($c); // Output Array ( [a] => 1 [b] => 2 ) What is going on here?? Why doesn't the second version also add the two arrays together? What have I misunderstood? What should I be doing instead? Or is it a bug in PHP?

  • Why is T() = T() allowed in C++?

    - by Rimo
    I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?

    - by tiny_clanger
    I started with the standard scriptaculous drag and drop tree, and that all works fine.

It's not in a form, and I can't find a way to serialize it to move onto setting up the AJAX update.

  • Contact page MVC workflow

    - by alex
    All my previous projects have had this workflow on Contact pages User submits form Controller gets $_POST details Controller validates details (and sets error messages if necessary) Controller sends email Controller redirects to thanks page Is this the standard workflow? I used to validate everything in controllers, and then did some more reading and they recommended against it. Therefore, should I send the $_POST details to a helper type object and let it do all the work (validation/sending)?
