Datagrid object bug in Visual Basic 6.0 (SP6)

Noticed strange bug or some undesirable feature while developing application in Visual Basic 6.0 IDE.  I have static Data objects drag & dropped on Form. Objects are of type Adodc and Datagrid. Adodc properties (ConnectionString and RecordSource) are empty. I fill them during run time and then refresh in my code. Then comes this bug. Datagrid which is connected to adodc object already at design time, tries to delete leftmost upper data grid cell content. And if database field allows empty value, then this deletion really happens. And it all goes on even data grid properties are set not to allow updates, additions and deletions. DataGrid control and ADO Data Control both are updated to Service Pack 6. I tried several things and finally found a workaround.

Canon Pixma Pro 100 driver installation in complex LAN environment

Guys from Canon have not really figured out all steps that comes out when installing Canon Pixma Pro 100 for several computers in Wi-Fi environment. When installing driver for first time and device (printer) is not configured yet and is empty, it is normal than we need somehow to configure Wi-Fi settings in the printer. For this we use CD with software (or download from Canon site) and a USB cable. Installation is straightforward. You set-up first computer, than you can remove USB wire because it is not needed any more. And you can then print through Wi-Fi. Difficulties come in situation when there is NAT between computers and Wi-Fi and you want to add several more computers.

HP Photosmart 5520 printer Wi-Fi connection problem and fix

When you are using HP Photosmart 5520 e-All-in-One printer it is possible that you are struggling with frequent disconnects in your LAN infrastructure. That was the situation with me too. I checked if printer receives statical IP address, if it has strong Wi-Fi signal. Reinstalled driver. Connected it by network name and also by IP. Nothing helped. During a day it several times lost connection and user was not able to print and to scan. After a while connection usually restored, but such unstable behavior was not acceptable. Then I tried one workaround.

Intel boosts JavaScript speed

Intel together with Firefox works on special API that accelerates JavaScript by using parallel computing power of modern processors. It could boost speed by 4 times or more. Interesting will this performance increase be available to other brands processor systems? Anyway parallel processing is very hot topic in these days and I believe we will soon hear more about speed improvements on personal computers and ordinary applications.
