Is there a program or software that first I would have to download onto computer and then from my computer onto my mobile's phone memory card to program then into the mobile phone for free phone call?

Are you asking for a way to use software to hack your phone in order to make free calls? I'm sure there's a way somewhere, somehow on a very small number of case-specific Mobile devices...

Phone usage is typically monitored remotely-- Your phone is borrowing bandwidth from cell towers, and your phone is clearly identified when it makes a connection to said cell tower. Conning your cell phone provider into giving you a free phone call is hardly worth the effort when you can simply use a free computer phone to make calls instead.

Where can one find information on clocking systems?

One can find information on clocking systems at Time Clock Window. This website is selling a software for time-keeping as well. Also they're selling the software for 60 dollars.

What are good computer cleaning websites?

If by clean you mean delete unneeded files, I use a commerical on my personal computer. It will automatically delete unneeded web caches, temporary files, or even whole applications that you don't want.

If by clean you mean speed up your computer dramatically, there isn't actually an application out there that will do that. Old computers can generally be sped up significantly by performing a factory reset (WARNING: this will DELETE ALL OF YOUR FILESexcept for the operating system).

Can you buy a really good computer for less than $500 dollars?

The Toshiba Satellite line has a number of quality computers under $500. You can choose from mini notebooks to 17" screens, 250-640 GB HDDs and several other options. I would highly recommend these computers to anybody who is looking for a computer for every day use.

First step you should take when creating a program?

The first step you should take when creating a program is to write an algorithm for it. An algorithm is a programming tool that offers a step by step solution to a programming problem.

Why do the people who answer these questions not bother to read them?

Hey, wait a minute here! :-) There's a big difference between serious contributors and stupid people or vandals. Serious answerers do read the questions thoroughly and try and answer them the best they can, which is clearly and to the point more often than not.

What is the different between computer cell and biological cell?

Computer cells are units of storage in a computer system, typically referring to a memory cell or a single unit in a spreadsheet. Biological cells are the basic structural and functional unit of all living organisms, containing genetic material and performing various cellular functions in the body. Both types of cells are fundamental units in their respective systems, but they operate in very different ways and serve different purposes.

How do you become famous on clubpnenguin?

you can't. This is simply because when clubpenguin was made up they also made up characters that people coule be friends with and show clubpenguins members new games. The famous ppl are only there for publicity

What is the purpose of The Computer Graphics Society?

The Computer Graphics Society is a networking page, similar to facebook, but caters solely to digital Artists. This page provides them with a platform to showcase their talents, as well as network and promote their craft to the world.

Why in Access can you not set an index to an OLEobject?

You use OLE Object fields to insert documents (Word, PDF, bitmap images, etc) into records. The OLE Object itself is actually a binary data field and the only way to compare any two OLE Objects is to compare the binary data itself. This makes no sense because we normally compare documents by type, size, author, title, creation date, last modified date, and so on, we don't compare their physical representations (the binary data itself). If we want to sort documents, we must extract the properties we wish to sort by and insert them as separate fields in our records, and use those fields as our index/sort keys.

Sometimes we really do need to use binary data as a sort key, but we cannot use an OLE Object to store that data because OLE Objects cannot be used as sort keys. Instead, we must use the built-in binary data field which can be indexed and sorted. Binary data fields can be fixed-length (binary) or variable length (varbinary). Note that OLE Objects are variable length with a theoretical limit of 1 GB, which is yet another reason why they are unsuitable for indexing. The fixed-length binary field has an upper limit of 510 bytes, making it ideal for indexing and sorting small amounts of binary data.

Unfortunately, the built-in binary data fields cannot be created using the table designer for no practical reason other than Microsoft decreed that you couldn't. Instead you must use DDL or VBA/DAO. Using DDL, the following will create a binary and a varbinary field. For completeness, I've also included an OLE Object field:

CREATE TABLE tblBinTestSQL (

Id counter NOT NULL PRIMARY KEY,

VarbinaryColumn varbinary(100) NULL,

BinaryColumn binary(100) NULL,

OLEColumn Longbinary NULL

);

Here's the VBA/DAO method of achieving the same thing:

Public Sub CreateBinaryColumns()

Dim td As DAO.TableDef

Dim db As DAO.Database

Dim fd As Field

Set db = CurrentDb

Set td = db.CreateTableDef("tblBinTestDAO")

Set fd = td.CreateField("ID", DataTypeEnum.dbLong)

fd.Attributes = fd.Attributes Or dbAutoIncrField

td.Fields.Append fd

Set fd = td.CreateField("BinaryColumn", DataTypeEnum.dbBinary, 100)

fd.Attributes = fd.Attributes Or dbFixedField

td.Fields.Append fd

Set fd = td.CreateField("VarbinaryColumn", DataTypeEnum.dbBinary, 100)

td.Fields.Append fd

Set fd = td.CreateField("OLEColumn", DataTypeEnum.dbLongBinary)

td.Fields.Append fd

db.TableDefs.Append td

End Sub

Once you have at least one table with a binary or varbinary field, you can simply copy that field to other tables. You can also modify the properties of those fields in table designer; you just can't use table designer to create those fields.

CCTV DVR Security: Connecting The Cables ?

When using a surveillance system at home, handling the wiring and hardware may become complicated. First, users must properly connect the video camera to the DVR or recording hard drive. Additionally, the security camera has to be plugged into an electrical outlet with a power cable. Then, the DVR must be connected to a TV, monitor, computer, router, or networking device. All of this requires knowledge of various data cable technologies such as HDMI, Ethernet, A/V, BNC, component, and others. It is also important to have sufficient cable length to make a proper connection between the camera and other devices which will be part of the surveillance system.

What is a hardware device that allows user store data?

A hardware device that allows users to store data is a hard drive, which can be either a traditional HDD (hard disk drive) or a solid-state drive (SSD). These devices provide a medium for saving files, applications, and the operating system, enabling users to access and manage their data efficiently. External storage options like USB flash drives and external hard drives also allow for portable data storage.
