C# example:how to get version/created time of assembly

1, We need function like this :

  public string GetServerInfo(Assembly _assembly)
    {
        StringBuilder r = new StringBuilder();
        try
        {
            r.AppendLine("Version:" + _assembly.GetName().Version.ToString());
            r.Append("Build: " + System.IO.File.GetLastWriteTime(_assembly.Location).ToString("dd/MM/yyyy HH:mm"));
        }
        catch (Exception ex)
        {
            Logger.prn(ex);
        }
        return r.ToString();
    }

Then we can call it like this :

Assembly _assembly = Assembly.GetExecutingAssembly();
string info= GetServerInfo(_assembly);

mysql how to select records with unicode characters

following select returning these records:
SELECT * FROM candidate WHERE CHAR_LENGTH(first_name)<>LENGTH(first_name);

mysql and php to fix character encoding

*  call mb_internal_encoding("UTF-8") at the head of my PHP scripts
*  MySQL tables all have DEFAULT CHARSET=utf8  > COLLATE=utf8_unicode_ci
*  call mysql_set_charset('utf8') immediately after I connect to the  DB with mysql_connect().
*  call header('Content-Type: text/html; charset=utf-8') before  outputting anything to the browser.
*  specify <meta http-equiv="Content-Type" content="text/html;  charset=utf-8"/> in the HEAD of my HTML.
*  FORM tags all have accept-charset="UTF-8".

vim commands

:g/search-string/norm @h  
runs a macro recorded in h for every match of search-string

Vim-style movement:
'h' 'j' 'k' 'l' for movement (Up, Down, Left, Right)
'gg' End
'G' Home
'0' Beginning of line
'$' End of Line
'H' Top of the Screen
'M' Middle of the screen
'L' Bottom of the screen

windows using
:split command or the ^w commands:

^wn - new window

^ws - horizontal split

^wv - vertical split

^wr - rotate windows

^ww/^wW - move to the next/previous window

^w= - make all windows equal size

^wc - close the active window

Load controls in asp.net dynamically

1.Add placeholder to .aspx

<asp:Panel ID="PlaceHolderPanel" runat="server">
   </asp:Panel>

2. add control loading code to codebehind :

string AlreadyLoaded=null;
private void loadControl(string ctr){
       if (!string.IsNullOrEmpty(ctr) && AlreadyLoaded!=ctr ) {
           Control ctrl = LoadControl(ctr);
           ctrl.ID="ctr1";
           PlaceHolderPanel.Controls.Clear();
           PlaceHolderPanel.Controls.Add(ctrl);
           ControlName = ctr;
           AlreadyLoaded=ctr;
       }

   }

protected void Page_Load(object sender, EventArgs e){
       loadControl("~/Controls/mycontrol.ascx");
}

There are limitations for loaded controls , one of them using onPreRender rather then Page_load:

// 1.call all functions in prerender only
protected override void OnPreRender(EventArgs e){
       SetFilterValues();
       Bind();
     base.OnPreRender(e);
}

C# how to use iterator

//  create iterator method 

      public IEnumerable<decimal?> BucketIterator(Accounts_basic a ) {
            int cycle = 0;
            for (int i=7 ; i > 0 ; i--){

                    switch (i) {
                 case 1:yield return a.dd_15;break;

                         case 2 :yield return a.dd_30; break;

                         case 3:yield return a.dd_60; break;

                         case 4:yield return a.dd_90; break;

                         case 5 :yield return a.dd_120; break;

                         case 6:yield return a.dd_150; break;

                         case 7:yield return a.dd_180; break;

                 default : yield break;

                }

            }

// use iterator method as follows
 foreach (decimal? amount in BucketIterator(accounts_basic)) {
        // use amount here 
}

is already mapped in workspace or removing other's working space

The path C:\Projects is already mapped in workspace PC123;DOMAIN\USER

tf workspaces /computer:PC123 /owner:* /format:detailed

And – sure enough, it looks like there’s another workspace for a different user profile – with the same PC name (PC123).
tf workspaces /computer:PC123 /owner:* /format:detailed /server:http://tfs:8080
================================
Workspace: PC123
Owner : *ME*
Computer : PC123
Comment :
Server : tfs.domain
Working folders:
====================================
Workspace: PC123
Owner : *SOMEONE-ELSE*
Computer : PC123
Comment :
Server : tfs.domain

Working folders:
$/AAA: C:\Projects
$/AAA/BBB/CCC: C:\Projects\AAA\BBB\CCC
Not sure how/why this has happened – perhaps a duplicate PC-NAME ?

Anyway – here’s the command to REMOVE the baaad workspace – clear it out all and start again.

tf workspace /delete PC123;other-user /server:http://tfs:8080
A deleted workspace cannot be recovered.
Workspace ‘PC123′ on server ‘http://tfs.8080′ has 0 pending change(s).
Are you sure you want to delete the workspace? (Yes/No) Y
