Undo pending changes from a specific user account

Uncategorized Leave a comment

 

If you want to undo some changes from a specific user, you can use:

 

Change directory to folder containing "tf.exe"
    • cd "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE"

Check the status of checked out files, to see correct "account"
    • tf status "$/TFS/Path/To/Folder/To/Search/For/Pending/Changes" /s:123.123.123.123 /u:* /recursive /format:detailed

Undo pending changes
    • tf undo /workspace:"S001";MyDomain\myUserName "$/TFS/Path/To/Folder/To/Search/For/Pending/Changes" /recursive

Server side resource rendering with Angular and ASP .NET MVC: pass data from html to controller.

Uncategorized One Comment

I wanted a ASP .NET MVC view (*.cshtml) to render on the server and pass the static text contained in the the ASP .NET project resource file to an Angular controller, so on the initial page request, all static data is returned to the client. Dynamic data, like grid content would then be requested by a separate JSON call.

The resource data is passed to the Angular controller by using ng-init.

 

For the sake of this blog post I stuffed everything in one *.cshtml page, including CSS en JavaScript.

Of course this would be separate files in an real application.

Using a recursive common table expression, to calculate totals and subtotals of children and grandchildren in a hierarchy

Uncategorized Leave a comment

In SQL Server a common table expression can be used to calculate totals / subtotals of a table containing hierarchical data:

 

-- Create test data:
if object_id('tempdb..#Hierarchy') is not null
begin
    drop table #Hierarchy
end

create table #Hierarchy (
    Id int not null,
    ParentId int null,
    Amount int not null
)

insert into #Hierarchy (Id, ParentId, Amount) values
    (1, null, 100)
,    (2, 1, 100)
,   (3, 1, 100)
,   (4, 1, 100)
,   (5, 4, 100)
,   (6, 4, 100)
,   (7, 4, 100)
,   (8, 7, 100)

;with CTE (ParentId, Id, Amount, IsParent)
as
(
    -- Add all records as "anchor", because foreach record we are going to calculate the total amount.
    select    h.ParentId
    ,        h.Id
    ,        h.Amount
    ,        0 as IsParent
    from    #Hierarchy h
    union all
    -- Recursively add parent records until root parent foreach record in "anchor".
    select    h.ParentId
    ,        h.Id
    ,        h.Amount
    ,        1 as IsParent
    from    CTE c
    join    #Hierarchy h on c.ParentId = h.Id
)

select        c1.Id
,            c1.ParentId
,            sum(c1.Amount) as TotalAmount
,            case when sum(c1.IsParent) > 0 then 1 else 0 end as IsParent
from        CTE c1
group by    c1.Id, c1.ParentId

How to manually get Angular services in TypeScript

Uncategorized Leave a comment

If you manually want to get / use Angular services in TypeScript you can use the following code:

 

/// <reference path="../libraries/angular/angular.d.ts" />

module app {
    "use strict";

    var appModule = angular.module("app", []);
    var injector: angular.auto.IInjectorService = angular.injector(["ng"]);
    var httpService: angular.IHttpService = injector.get("$http");
    var qService: angular.IQService = injector.get("$q");
}

Fix favicon error

Uncategorized Leave a comment

When there is no favicon.ico in the root of your website, then the browser will automatically get a 404 favicon error.
To prevent this error, you can add a transparent favicon.ico to the “head” tag of your HTML page:

<link rel="icon" href="data:;base64,iVBORw0KGgo=">
