This looks like a VERY cool project! Thanks for releasing it...

I grabbed the MSI, installed it (on Vista), but don't see the solution/source. The C:\Program Files\Microsoft VLinq Query Builder\ folder only has the bin's, ico, etc

Is the MSI only bin's or does it also contain the source?

Thanks,

I tried to sign in on the code-website but that does not seem to work.

installed on VS 2008 Pro RTM on Vista Ultimate x86.

not working, no designer icon in vs items.

something in setup is not working.

the files are there ... looks like VS has the stuff.

perhaps we need to run devenv with a packages command ??

mitsu — Thu, 03 Apr 2008 02:21:53 GMT

Very strange. Can you check the file 'VLinq queries.zip' is in \Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp\1033

If so, close all VS instance and try 'devenv /installvstemplates'

Hello VinceX.NET,

Did you try to run the setup as admin ?

If you have both VS2005 and VS2008 installed, then after installation, run the VS2008 command line and enter "devenv.exe /installvstemplates".

Hi Mitsu!

Thanks! Seems to be a great tool!

I've tried installing it on 'VS.NET Team Suite 2008 RTM' without success. The installation ends successfully but "VLinq Query" item is not addded to the item list. Following your guides, I checked "\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp\1033". It didn't contain the 'VLinq queries.zip' file so I added it from the sources by hand and ran 'devenv /installvstemplates'. This time 'VLinq query' was shown in the items list but when I try to invoke the designer of my VLinq query, I get the error 'cannot locate resource 'querybagdesigner.xaml'.

My Windows is XP SP2.

Any ideas what the problem is?

No! I am using the English version of Windows XP. I've just noticed one problem. My Visual Studio is installed on 'D:\Program Files\Microsoft Visual Studio v9.0' but the item templates copied by the installer is put on 'C:\Program Files\Microsoft Visual Studio v9.0'. I've put them in the correct path manually but still the same problem with finding 'querybagdesigner.xaml'.

Judging by all the problems everyone is having, the installation obviously wasn't tested on Vista. I suggest you test it on several Vista machines and release a version that works. And the devenv /installallvstemplates hack? It removes all my templates! Yes, I ran it all 'as Administrator'.

re: Visual Linq query builder for Linq to Sql: VLinq

mitsu — Sat, 19 Apr 2008 20:09:57 GMT

@Dave: sounds strange. When in the property editor, make sure you have checked the radiobox correctly in addition to providing the connnection string.

Yes, recompilation is asked many times. We are using the project compiled information to run the query which is a strange choice but which allows to execute the query in a very close environment that what the user will have at runtime. This part has to be optimized because we ask for recompilation at each time the document is modified (even if it does not generates new code). I hope to solve this point in the next release.

When I try to use the tool to do a join I get this error: "The Property "StatusId" type is not valid in a join declaration". I know I could just reference Status from within the Group table but I'm just trying to see if the join functionality works.

re: Visual Linq query builder for Linq to Sql: VLinq

nealb — Mon, 12 May 2008 18:39:48 GMT

Nice effort, however the tool is extremely confusing! I wasn't able to create a single query, because the tool is not intuitive at-all. The article was my only hope and it leaves-out far too many details during the walk-through. For example: I have no idea how the author proceeded from a "New (blank) Query" to this screen, showing a datasource: http://blogs.msdn.com/blogfiles/mitsu/WindowsLiveWriter/VisualLinqquerybuilderforLinqtoSqlVLinq_A02A/clip_image016_2.jpg

When I tried to add a datasource, all I saw was a blank dialog with no obvious purpose.

The flashing and zooming graphics are neat, but the tool is buried so far down in the IDE and it is too hard to find and the tools' UI is far too vague.

Nice initial effort, but this thing needs a lot more work before I can recommend it to my team. I hate to be the dissenter here, but someone had to say it.

Thanks anyway

re: Visual Linq query builder for Linq to Sql: VLinq

mitsu — Tue, 13 May 2008 02:22:28 GMT

Hi nealb,

Even if many people found it easy to use, I take your point. The best I can recommand is to look at the webcast (see link on the project page).

Just to remind, this is a free tool developed by interns. One of the goals was to test what kind of new UI we could make for a visual studio addin using WPF. It's maybe not intuitive for everyone but I think it's an interesting try. We will fix some issues but we did not plan to 'work' again on this project. It's free, the source code is provided and I think it's already a good thing !

2. When I press the Preview button, It displays "No Data. If your query..." (sorry, I couldn't cut and paste)

3. When I first create a query it adds my namespace to the Type when generating the code as in:

from b in context.GetTable<Namespace.Brand>()

when I manually remove the namespace. it compiles correctly.

re: Visual Linq query builder for Linq to Sql: VLinq

sam2008 — Mon, 20 Oct 2008 08:52:55 GMT

LINQ defines a set of query operators that can be used to query, project and filter data in arrays, enumerable classes, XML, relational database, and third party data sources. While it allows any data source to be queried, it requires that the data be encapsulated as objects. So, if the data source does not natively store data as objects, the data must be mapped to the object domain. Queries written using the query operators are executed either by the LINQ query processing engine or, via an extension mechanism, handed over to LINQ providers which either implement a separate query processing engine or translate to a different format to be executed on a separate data store (such as on a database server as SQL queries). The results of a query are returned as a collection of in-memory objects that can be enumerated.

Great product. But I will be damned if I can get it to work. No matter what config I try I get a connection failed error. I have a server explorer connection created, and I am able to open and edit items via that. I have also coded a simple query based off the datacontext and that works fine. I have tried to use the VS connections and the custom connections. Neither of these work.

Hello,

This tool looks really good, however I am a little lost. I have read the posts here and many have helped (e.g. needing to run 'devenv /installvstemplates'). However I am unable to figure out how to set the connection string.

I would like to know if you can describe in more details how to get to this dialog: http://blogs.msdn.com/blogfiles/mitsu/WindowsLiveWriter/VisualLinqquerybuilderforLinqtoSqlVLinq_A02A/clip_image012_2.jpg

The property window I see for the vlinq class does not have a connection string option. I have also noticed that the video shows a different version of vlinq. I was wondering if I have the wrong version. If so, can you provide a URL for the newest version?

Thanks,

Will

I have just stumbled upon this amazing tool and I have to say thank you it is really amazing what you have achieved, it is a real help.

One thing I want to do and I do not know if it is supported is to get things make more complicated select citereon. For example I want to get a weighted average eg: sum(a*b)/sum(a) where a and b are some values in the table. I would do this with a lambda expression normally as say:

Group.Sum(Function(f) f.a * f.b) / Group.Sum(Function(f) f.b)

I cannot seem to do something like that in your tool but wondered if perhaps it was possible and I was just missing something simple?

Thanks again for a great piece of work
