  • Easy way to add multiple existing .csproj to a Visual Studio Solution?

    - by Michael J Swart
    I've checked out a branch of C# code from source control. It contains maybe 50 projects in various folders. There's no existing .sln file to be found. I intended to create a blank solution to add existing solutions. The UI only lets me do this one project at a time. Is there something I'm missing? I'd like to specify a list of *.csproj files and somehow come up with a .sln file that contains all the projects.

  • Foreign key refering to primary keys across multiple tables?

    - by sanjay bharkatiya
    hi , i have three tables say city,state and road 1) city - city_id(PK),name 2) state- Stt_id(PK),name 3) Road- Edge_id(PK), Admin_id(FK) where Admin_id refers to city_id and Stt_id both. This is done because the tables are too huge. say city_id contains 1,2,3 and Stt_id contains 4,5,6 now if i am inserting 1,2,3,4,5,6 in admin_id it is throuing an error .. what is the solution of my problem, regards sanjay

  • ADO.NET Multiple simultaneous reads from an open database.

    - by Deverill
    Answer not needed - my logic was wrong and this question is invalid. Charles helped me see where I went off-tracks. Thanks I have a utility that moves data from one source to another. In the process of writing the record I check to see if it exists and do an update/insert as necessary. The difficulty I have is that as I'm writing the main record info there is a 2nd table for "custom data" that I have to check to see if it exists and do an update/insert for that as well. Example: I may be loading a pencil sharpener that may or may not exist. While I'm writing it into destination it has characteristics such as style, color, etc. and each of them may or may not exist. As written I seem to need to have 2 DataReaders open, one for the sharpener and one to check for and update color. I am new to ADO.NET, but not to programming and it's more complicated than I listed but for sanity's sake I didn't put all the details. My question is: What am I missing? You can't have 2 readers open at the same time on a connection, yet I can't close the first if I'm stepping through all products. It seems inefficient to have 2 connections, readers, etc. for this. Is there a feature of ADO.NET DBs that I'm missing? How would you do it? Thanks!

  • LINQ to SQL - How to efficiently do either an AND or an OR search for multiple criteria

    - by Dan Diplo
    I have an ASP.NET MVC site (which uses Linq To Sql for the ORM) and a situation where a client wants a search facility against a bespoke database whereby they can choose to either do an 'AND' search (all criteria match) or an 'OR' search (any criteria match). The query is quite complex and long and I want to know if there is a simple way I can make it do both without having to have create and maintain two different versions of the query. For instance, the current 'AND' search looks something like this (but this is a much simplified version): private IQueryable<SampleListDto> GetSampleSearchQuery(SamplesCriteria criteria) { var results = from r in Table where (r.Id == criteria.SampleId) && (r.Status.SampleStatusId == criteria.SampleStatusId) && (r.Job.JobNumber.StartsWith(criteria.JobNumber)) && (r.Description.Contains(criteria.Description)) select r; } I could copy this and replace the && with || operators to get the 'OR' version, but feel there must be a better way of achieving this. Does anybody have any suggestions how this can be achieved in an efficient and flexible way that is easy to maintain? Thanks.

  • How do you limit a page with multiple flash mp3 players to play one at a time?

    - by Andrew.S
    I am working with the open source flash player at http://flash-mp3-player.net/ and I am trying to figure out how to limit one sound file at a time. I know this has been done on a number of sites but I am unsure how to approach it. Scenario: A page has five different instances of the flash player. The user is litening to one song but clicks on another to listen to it. Goal: The first audio file automatically stops while the second starts playing instead of both playing at the same time. Do I need to have some sort of javascript handler than interacts with the swf or something?

  • Why does C++ not allow multiple types in one auto statement?

    - by Walter
    The 2011 C++ standard introduced the new keyword auto, which can be used for defining variables instead of a type, i.e. auto p=make_pair(1,2.5); // pair<int,double> auto i=std::begin(c), end=std::end(c); // decltype(std::begin(c)) In the second line, i and end are of the same type, referred to as auto. The standard does not allow auto i=std::begin(container), e=std::end(container), x=*i; when x would be of different type. My question: why does the standard not allow this last line? It could be allowed by interpreting auto not as representing some to-be-decuded type, but as indicating that the type of any variable declared auto shall be deduced from its assigned value. Is there any good reason for the C++11 standard to not follow this approach? There is actually a use case for this, namely in the initialisation statement of for loops: for(auto i=std::begin(c), end=std::end(c), x=*i; i!=end; ++i, x+=*i) { ... } when the scope of the variables i, end, and x is limited to the for loop. AFAIK, this cannot be achieved in C++ unless those variables have a common type. Is this correct? (ugly tricks of putting all types inside a struct excluded) There may also be use cases in some variadic template applications.

  • How can one put together multiple arrays into one string?

    - by Noor
    I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

  • How can match end-of-line multiple times in a regex without interpolation?

    - by harschware
    Hi, if I have a input with new lines in it like: [INFO] xyz [INFO] How can I pull out the xyz part? I tried a pattern like /^\[INFO\]$(.*?)$\[INFO\]/ms, but perl gives me: Use of uninitialized value $\ in regexp compilation at scripts\t.pl line 6. I've been trying things to get interpolation to stop like using qr// but alas, no love. EDIT: The key is that the end-of-line anchor is a dollar sign but at times it may be necessary to intersperse the end-of-line anchor through the pattern. If the pattern is interpolating then you might get problems such as uninitialized $\. For instance an acceptable solution here is /^\[INFO\]\s*^(.*?)\s*^\[INFO\]/ms but that does not solve the crux of the first problem. I've changed the anchors to be ^ so there is no interpolation going on, and with this input I'm free to do that. But what about when I really do want to reference EOL with $ in my pattern? How do I get the regex to compile?

  • How do I get this sql to linq? Multiple groups

    - by Dwight T
    For a db person, LINQ can be frustrating. I need to convert the following SQL into Linq. SELECT COUNT(o.objectiveid), COUNT(distinct r.ReviewId), l.Abbreviation FROM Objective o JOIN Review r on r.ReviewId = o.ReviewId and r.ReviewPeriodId = 3 and r.IsDeleted = 0 JOIN Position p on p.PositionId = r.EmployeePositionId and p.DivisionId = 2 JOIN Location l on l.LocationId = p.LocationId GROUP BY l.Abbreviation The group by nested example might be the way I have to go, but not sure. Doing one group by I have used the following code: var query = from rev in db.Reviews .Where(r => r.IsDeleted == false && r.ReviewPeriodId == reviewPeriodId) from obj in db.Objectives .Where(o => o.ReviewId == rev.ReviewId && o.IsDeleted == false) from pos in db.Positions .Where(p => rev.EmployeePositionId == p.PositionId && p.IsDeleted == false && p.DivisionId == divisionId ) from loc in db.Locations .Where(l => pos.LocationId == l.LocationId) group loc by loc.Abbreviation into locgroup select new ReportResults { KeyId = 0, Description = locgroup.Key, Count = locgroup.Count() }; return query.ToList(); What is the correct way? Thanks

  • Why Is my UISlider Thumb Image Being Shown Multiple Times and Not Disappearing As They Should?

    - by Gorgando
    This slider is possessed: When I move the slider thumb left or right, it leaves the original image there (creating an extra image). This doesn't happen every time and the only consistency i've noticed is that it's inconsistent. When the table is in "Editing mode" it is more likely to create a duplicate thumb image, but it also does so in regular mode. This is the code that I use to create the slider: CGRect frame = CGRectMake(20, 42.0, 280.0, 22); self.slider = [[UISlider alloc] initWithFrame:frame]; [self.slider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged]; self.slider.continuous = YES; self.slider.minimumValue = 0.0; self.slider.maximumValue = 5.0; self.slider.value = 0.0; [sliderCell addSubview:self.slider]; Appreciate any thoughts you might have!

  • How do I define a template class and divide it into multiple files?

    - by hkBattousai
    I have written a simple template class for test purpose. It compiles without any errors, but when I try to use it in main(), it give some linker errors. main.cpp #include <iostream> #include "MyNumber.h" int wmain(int argc, wchar_t * argv[]) { MyNumber<float> num; num.SetValue(3.14); std::cout << "My number is " << num.GetValue() << "." << std::endl; system("pause"); return 0; } MyNumber.h #pragma once template <class T> class MyNumber { public: MyNumber(); ~MyNumber(); void SetValue(T val); T GetValue(); private: T m_Number; }; MyNumber.cpp #include "MyNumber.h" template <class T> MyNumber<T>::MyNumber() { m_Number = static_cast<T>(0); } template <class T> MyNumber<T>::~MyNumber() { } template <class T> void MyNumber<T>::SetValue(T val) { m_Number = val; } template <class T> T MyNumber<T>::GetValue() { return m_Number; } When I build this code, I get the following linker errors: Error 7 Console Demo C:\Development\IDE\Visual Studio 2010\SAVE\Grand Solution\X64\Debug\Console Demo.exe 1 error LNK1120: 4 unresolved externals Error 3 Console Demo C:\Development\IDE\Visual Studio 2010\SAVE\Grand Solution\Console Demo\main.obj error LNK2019: unresolved external symbol "public: __cdecl MyNumber::~MyNumber(void)" (??1?$MyNumber@M@@QEAA@XZ) referenced in function wmain Error 6 Console Demo C:\Development\IDE\Visual Studio 2010\SAVE\Grand Solution\Console Demo\main.obj error LNK2019: unresolved external symbol "public: __cdecl MyNumber::MyNumber(void)" (??0?$MyNumber@M@@QEAA@XZ) referenced in function wmain Error 4 Console Demo C:\Development\IDE\Visual Studio 2010\SAVE\Grand Solution\Console Demo\main.obj error LNK2019: unresolved external symbol "public: float __cdecl MyNumber::GetValue(void)" (?GetValue@?$MyNumber@M@@QEAAMXZ) referenced in function wmain Error 5 Console Demo C:\Development\IDE\Visual Studio 2010\SAVE\Grand Solution\Console Demo\main.obj error LNK2019: unresolved external symbol "public: void __cdecl MyNumber::SetValue(float)" (?SetValue@?$MyNumber@M@@QEAAXM@Z) referenced in function wmain But, if I leave main() empty, I don't get any linker errors. What is wrong with my template class? What am I doing wrong?

  • How do you write multiple lists from Matlab to the same excel file?

    - by Ben Fossen
    I have several lists in Matlab that I want to write to the same excel file. I have one list xordered and another list aspl. I do not know the length of the lists till after I run the Matlab program. I used data = xlswrite('edgar.xls',fliplr(sortedx'),'A2:A3000') for the first list but when I tried to write another list to the same file like this I ended up with two different excel files named edgar.xls asp_data = xlswrite('edagr.xls', fliplr(aspl'), 'B2:B3000') Is there a way I can write both of these lists into the same excel file? xordered in the A column and aspl in the B column?

  • Indesign and XML - how to auto flow into multiple pages with differing styles?

    - by MetaDan
    Hi guys, I've got a bit of a problem at the moment. I'm trying to work with indesign (cs3) and xml. Basically i have a template which is has 1 master dps, both pages have the same data (fields 1-5) but one is left aligned, one right - hence mildly different paragraph styles. What i want to be able to do is import xml and have indesign flow the data from the individual nodes into many pages. eg xml format: root day field1 field2 field3 field4 field5 day field1 field2 field3 field4 field5 day ... I can almost make this work by tagging the frames on the master pages, then creating pages and importing the xml, however it only flows the first 2 nodes into the pages reptitively for the total count of all the nodes. I can also almost make it work by creating a page from the untagged masters and then tagging the frames with the field1-5 tags then importing the xml. This populates the first page, however i then can't find a way to make the rest of the data flow into new pages... Am I missing something? Am I being a complete dumbass? If anyone can offer any help it will be greatly appreciated...

  • How to virtually delete data from multiple tables that are linked by a foreign key ?

    - by Shantanu Gupta
    I am using Sql Server 2005 This is a part of my database diagram. I want to perform deletion on my database which will start from tblDomain up tp tblSubTopics. Consider that each table has IsDeleted column which has to be marked true if request was made to delete data. But that data shoud remain their physically. Tables which will have IsDeleted Column are tblDomain tblSubject tblTopic tblSubTopic Now I want, if a user marks one domain as deleted then all the refrence field should also get marked as deleted. i.e. 1 domain is related to 5 subjects, those 5 subjects are related to 25 topics, those 25 topics are related to 500 subtopics and so on. Then how should i mark all these fileds as Deleted. ?

  • deriving activity diagram-based GUIs and CRUD them with a DB?

    - by Xin Tanaka
    i received a big book full of processes. i was thinking about the end user (they will be lawyers) and decided the best GUI would be showing activity diagrams or business processes. It reminded me Quickbooks and how non-accountants can successfully use it and understand accounting processes. i began doing research before sending my project to a bunch of programmers: is there some open source solution? can i use MS Visio libraries? which UML tool is programable? what about Eclipse and its modeling tools? etc etc the key points here are: relationships between events, artifacts, actors, etc should be stored in a database. processes or steps in a process should be easily modified by updating the database do this sounds too crazy? (should I explain a bit more why it must be programmed this way?)

  • How to deploy and configure many copies of an application to multiple domains on the same server

    - by Oren
    We are about to begin work on an application that will eventually be deployed many times on one server. I am hoping to build a nice interface so that one of my coworkers can easily create new deployments of this application. The idea is to create a wizard with a series of options that will configure basic properties of each particular copy of the app such as color scheme, domain name, etc. Each copy of the application may be further tweaked independently down the line. I would like to know what is the best way to manage the automatic creation of users, the updating of domain name info and the deploying of copies of an application, with the ability to maintain certain discrepancies between each of these copies (such as installed plugins, different CSS) as we update the application in the future. What I'm asking is extremely similar to the way StackExchange 1.0 functioned, where a user could configure several options and a customized version of the StackExchange would soon be up and running. How is this accomplished?
