Macro That Automatica​lly Updates Data Itself In Excel If you need to have a database that automatically updates itself.  In fact, if you have a folder with different excel files, say folder Y (all the same form/template), and the first X cells of these files need to be extracted to another excel workbook (file Z). Every file represents 1 row in workbook  Z. But this should be done automatically. So if I copy a new excel file in folder Y, the first X of this new excel file should automatically (can be with a ‘button demand’)  be copied into workbook Y. Option Explicit Const cstFolder = "C:\Users\ATC0155\Documents\Toolbox\Excel\1208 20 selfupdate" Const cstCols = 5 Sub DoUpdate() Dim wks As Worksheet Dim strFile As String Dim appExcel As Excel.Application Dim lngRow As Long ' Prepare the sheet to receive the data Set wks = Sheet1 wks.Cells.ClearContents ' Run through each file in the folder strFile = Dir(cstFolder ...

Delegate is neither meant to do any action nor to persist a value. so there is no need to access the delegate by an object. And we can even declare the delegate outside of the class. There is no significant in declaring the dele...

Concept of etworks Consist of two or more computer connected to each other. Share resources (such as disks, files,directories, printers, CD-ROMs etc.) Exchange files, data and allow electronic communication between them. Types of Networks Local Area Network (LAN) Metropolitan Area Network (MAN) Wide Area Network (WAN) Local Area Network Confined to a relatively small area. Generally limited to a geographical area such as a school, building or an office. Rarely are LAN computers more than a mile apart. Metropolitan Area Network (MAN) Covers larger geographical areas, such as cities. Wide Area Network Connects larger geographical areas, such as the whole of India or the world. Dedicated transoceanic cabling or satellite communication may be used to connect this type of network. Peer-to-peer operations Peer-to-peer operations All computers are considered equal. Designed primarily for small to medium local area networks. Advantages Less initial expense ...

You can still get some information from your dump tapes, and with a couple of educated guesses, you can get the system up and running. There are a couple of ways to proceed. If you have another system, and you have some spare disk space, you can start to gather some information while the hardware guy is replacing the disk drive. On the second system, create a directory on a file system that has at least 15 MB free. You probably won't use that much, but a little extra space never hurts. In a crunch, you could probably get by with 5 MB or less. Let's call the directory /hope (because we hope we can get some information out of this). We are going to use the interactive option to ufsrestore (this option is also in restore under Sun OS, but I will use the Solaris versions here) to extract the vfstab from the dump tape. Use the following commands: # cd /hope # ufsrestore -ivf /dev/rmt/0 Verify volume and initialize maps More messages concerning block size, date of the dump, ...

From the boot prompt (the 'OK' prompt) type: OK boot cdrom -s When the system has booted up, you should be at a shell prompt. You'll need to partition the disk using format. # format c0t0d0 You will see the format menu. It is usually not necessary to actually format the disk, since almost all SCSI disks are preformatted at the factory. We simply need to repartition the disk. Select the partition option: format> partition You will see the partitioning menu. Enter the following commands, using the printout of your previous partition layout in that machine's logbook as a guide. (See comments about partition sizes later in this article if you don't have such a record.) partition> 0 Enter partition id tag[root]: Enter partition permission flags[wm]: Enter new starting cyl[0]: Enter partition size[??b, ??c, ??mb, ??gb]: Repeat this process for all the other slices on the disk. Be sure to zero out any unused slices on the disk to avoid problems later....

1. Disasters  Its statistics are almost similar to any other parts of the ocean. various authors just exaggerate things based on their beliefs in the myths. There are also errors in the data . for example a ship reported missing may be taken into account but it may show up two days later .and this will not be recorded. 2. Things Dissolve  I don't know what this means .but i would not be very surprised if sugar dissolves in the Bermuda triangle. 3. Magnetism ... there is no evidence of extreme magnetic force . but the compass readings do vary over the triangle area ... and not just the there but everywhere on earth. The compass reading usually varies over a particular geographic region. I think the Bermuda triangle hides a warm hole or a singularity in it "nature abhors naked singularity" i mean if u say its due to magnetic field , how do u explain the reappearance of ships or old things that were experienced by the people magnetic field doesn't play hide...

Here are a few interview tips to help you make a great impression on the person who interviews you. 1 . Market your skills and related experience in the field that you are applying for.

Prepare answers to common interview questions ahead of time, and practice saying them, so you aren't stumped during the interview. 4 . Dress for success, in the manner you would dress for the position you're seeking. 5 . Bring a list of your own questions with you in a folder with the company's name on it, so that you don't forget them. You should keep your extra resumes in there too. 6 . Be a good listener and focus. Some job seekers talk too much during interviews. 7 . Be prepared to describe y...
