deleting “Could Not Find This Item” folder!

Very annoying bugs in windows. Happen to me twice. Restart still wont be able to delete

How to delete? Lets say the problem folder is c:\parent\the_stubborn_child

1. Open command prompt
2. change directory to that particular parent folder using cd command
e.g:
cd c:\parent

3. type dir /x. this will show the dos short name
4. delete the folder with this command : rmdir <short file name>
5. feel good about it

sharing global variables between function guide matlab

There might be a situation where you need to share variables between functions callback in matlab gui for example using variables which are initiated during gui start. There are 2 ways to do this

1. using global variable

function gui_OpeningFcn(hObject, eventdata, handles, varargin)
global x y z;
x = 1;
y = 2;
z = 3;

function pushbuttonNext_Callback(hObject, eventdata, handles)
global x y z;

x = x+1
y = y+1
z = z+1

function pushbuttonPrevious_Callback(hObject, eventdata, handles)
global x y z;

x = x-1
y = y-1
z = z-1

  2. using guidata

function gui_OpeningFcn(hObject, eventdata, handles, varargin)
x = 1;
y = 2;
z = 3;

handles.x = x;
handles.y = y;
handles.z = z;

guidata(hObject, handles);


function pushbuttonNext_Callback(hObject, eventdata, handles)
handles.x = handles.x + 1;
handles.y = handles.y + 1;
handles.z = handles.z + 1;

guidata(hObject,handles);

function pushbuttonPrevious_Callback(hObject, eventdata, handles)
handles.x = handles.x - 1;
handles.y = handles.y - 1;
handles.z = handles.z - 1;

guidata(hObject,handles);

*note that line 10, 18, 25 is called to save the variable in guidata structure so we are able to access in from other function scope

Redirect subfolder outside htdocs in apache

Lets say you have a folder with path "D:\myfolder\abc" and you want the address "http://localhost/web" to redirect to this folder instead of "C:\xampp\htdocs" as usual Add these lines to "httpd.conf" (located in "C:\xampp\apache\conf\")

Alias /fyp D:\myfolder\abc
<Directory D:\myfolder\abc>
 Require all granted
 Order allow,deny
 allow from all
</Directory>

fix phpmyadmin error #1146

For some reason in xampp  version 1.8.3-3 in default installation you will face error #1146 ('phpmyadmin.pma_table_uiprefs' doesn't exist) when trying to query table in phpmyadmin.

 

 To solve this issue : A. you can run  create_tables.sql inside "phpMyAdmin\examples" folder OR B. comment the advanced features settings 1. Find these lines in config.inc.php and comment them

/* User for advanced features */
//$cfg['Servers'][$i]['controluser'] = 'pma';
//$cfg['Servers'][$i]['controlpass'] = '';

/* Advanced phpMyAdmin features */
//$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
//$cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';
//$cfg['Servers'][$i]['relation'] = 'pma_relation';
//$cfg['Servers'][$i]['table_info'] = 'pma_table_info';
//$cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';
//$cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';
//$cfg['Servers'][$i]['column_info'] = 'pma_column_info';
//$cfg['Servers'][$i]['history'] = 'pma_history';
//$cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';
//$cfg['Servers'][$i]['tracking'] = 'pma_tracking';
//$cfg['Servers'][$i]['userconfig'] = 'pma_userconfig';
//$cfg['Servers'][$i]['recent'] = 'pma_recent';
//$cfg['Servers'][$i]['table_uiprefs'] = 'pma_table_uiprefs';
