eclipse reduce tab height

Simple and definitive guide for this annoing problem

Every Linux GTK (and not only) them present horrible Eclipse IDE
I'm working with:
CentOs 7 GUI
Eclipse Mars 4.5

You can customize file in this path:

$YOURHOMEDIR/.p2/pool/plugins/org.eclipse.ui.themes_x.x.x.x.V.xxxxxx/e4_default_gtk.css

Modify css class as:

.MPartStack {
  font-size: 9;
  font-family: Liberation Sans;
  swt-tab-renderer: null;
  swt-tab-height: 22px;
  swt-selected-tabs-background: #FFFFFF #ECE9D8 100%;
  swt-simple: false;
  swt-mru-visible: false;
}

to obtain decent tab style

Alternative to yuo can install Eclipse plugin :

Go to menu Help > Install new software, then install E4 CSS editor (Incubation) plug-in using update site (add this link: http://download.eclipse.org/e4/updates/0.12).

After restart, go to Window > Preferences, General > Appearance and now you can edit styles here for any selected theme

MysqlException Number Code List

When we catch exception using, for example, mysql net connector we can go deep and find out error.
We can discover error code, checking property Number of class MySqlException.



try
{
 connection.Open();
}
catch (MysqlException ex)
{
 switch (ex.Number)
                {
                    case 0:
                        return "Cannot connect to server";
                        break;

                    case 1045:

Cenots set Fully Qualified Domain Name Glasshfish problem

How to configure fqdn on centos for your linux box on private lan
Remeber that domain must be always full qualified,  domain + extension  (local + .com)

Example data:
Server Name ----------------------------------- gffp01t
Static ip ----------------------------------------- 192.168.1.191
Local domain (for your lan example) ------ local.com 

1 Edit Hosts File
$ sudo vim /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
127.0.0.1 gffp01t.local.com gffp01t
192.168.1.191 gffp01t.local.com gffp01t
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 
::1 gffp01t.local.com gffp01t

2 Edit network $ sudo vim  /etc/sysconfig/network HOSTNAME=gffp01t.local.com

.....
Reboot system  
.....

4 Verify
$ hostname
(output) gffp01t.local.com
$ hostname -f
(output) gffp01t.local.com

NSIS customize files based on languages

 NSIS How to get user selected language without using registry function

This is an example based on my custom needed to rename config file for my application based on language selection by user during setup 

First onInit function you must pop $LANGUAGE variable on global stack as you can retrive it later.

Function .onInit
....
....
!insertmacro MUI_LANGDLL_DISPLAY
 Pop $LANGUAGE

FunctionEnd

Then on interested section you wite your custom language files (D_MyApp..... E_MyApp.... F_MyApp...)

Section "MainSection" SEC01
  SetOutPath "$INSTDIR"
  SetOverwrite try
  SetDetailsPrint none
  SetShellVarContext all
  File "D:\projects\xxxxx\MyApp_v32_09082013\D_MyApp.exe.config"
  File "D:\projects\xxxxx\MyApp_v32_09082013\E_MyApp.exe.config"
  File "D:\projects\xxxxx\MyApp_v32_09082013\F_MyApp.exe.config"

 Here you compare $LANGUAGE with LCID value  (see http://www.science.co.il/Language/Locale-codes.asp  for reference)
If selected language match then rename file else continue if statement

  StrCmp $LANGUAGE '1031' customGerman noDE
  customGerman:
  Rename "$INSTDIR\D_MyApp.exe.config" "$INSTDIR\MyApp.exe.config"
  goto languageSettingsDone
 
  noDE:
  StrCmp $LANGUAGE '1033' customEnglish noEN
  customEnglish:
  Rename "$INSTDIR\E_MyApp.exe.config" "$INSTDIR\MyApp.exe.config"
  goto languageSettingsDone

  noEN:
  StrCmp $LANGUAGE '1036' customFrench noFR
  customFrench:
  Rename "$INSTDIR\F_MyApp.exe.config" "$INSTDIR\MyApp.exe.config"
  goto languageSettingsDone
 
  noFR:
  goto languageSettingsDone
 
  languageSettingsDone:
....

Crystal Reports filed text newline, carriage return, \r\n

Nel mio crystal report ho un textFiled, vorrei settare il suo valore runtime.

rpt.DataDefinition.FormulaFields["fieldTarga"].Text =TextBoxTarga.Text;

Tutto funziona correttamente, fino a quando il valore da assegnare non contiene i caratteri speciali linefeed e carriage return "\r\n". Questo è un bug di Crystal Report for .NET 

Per risolvere il problema, anche se di primo acchito appare insensato, possiamo ovviare usando questa semplice funzione:

string FormatCRField(string s)
        {
            return "'" + s.Replace("\r\n", "' + chr(10) + '") + "'";
        }

Sostituisce "\r\n"  con chr(10) che verrà interpetato correttamente dal "parser" di CR.

Spero che questo possa aiutarti.
