An archive of solutions of programming problems I have faced in my career
View controllers in Ext JS can only listen to events coming from controls within the parent view.
It cannot listens to events from other sources outside of the parent view, or global events.
Use Controllers to facilitate collaboration between view controllers and different views.
One of the reasons why a connection to WCF services cannot be made due to security issue is due to time difference between the client and the server machine.
If you found this issue, synchronizing the time between the client and the server may resolve it.
When mapping a SQL table to a model using Hibernate or NHibernate, if you configure the mapping like following
<property name=”MyDecCol” type=”Decimal” precision=”28″ scale=”15″>
<column name=”MyDecCol” sql-type=”decimal” not-null=”false” />
</property>
For some reason, Hibernate/NHibernate will treat the field as a decimal with scale = 5 (5 decimal digits on the right side of the decimal separator). So if you save a value to this column with more decimal digits, it will be truncated to only 5 decimal digits.
I’m not sure why, but if you move the attributes to the inner column element, Hibernate and NHibernate will map the values correctly.
<property name=”MyDecCol” type=”Decimal”>
<column name=”MyDecCol” sql-type=”decimal” not-null=”false” precision=”28″ scale=”15″ />
</property>

It’s really confusing, Microsoft really needs to work on naming things.

Add a handler for AcquireRequestState event.
Write a handler for AcquireRequestState event to get the route data of the request from route table.
Set a breakpoint to peak into the route data when debugging.
Not sure why but following works
-Open the VM manager, detach the virtual network adapters.
-Reattach the network adapters/
After this, RDP starts working.
Use nmap in linux or cygwin/mingw
nmap –script ssl-enum-ciphers [hostname]
I was trying to install qark, an android security program, through pip.
After installation, the readme say to run qark –help. However the system cannot find this command.
After trying python -m quark.py, python quark.py, etc with no result. I managed to solve by finding out that the Script folder of the Python installation contains the .exe file for qark, qark.exe.
Adding this folder to my PATH environment variable allows running this command in the command prompt.
This should be something to be mentioned in the readme at least.
Model properties are all null after retrieving from POST request.
Check if they are properties instead of attributes.
Example: instead of
public String property;
Use
public String property { get; set; }
Use this in the config for the combo box. Replace display with the actual name of the display field.
listConfig: {
itemTpl: '<tpl for=".">{display:htmlEncode}</tpl>'
},
