Excel VBA copy or reference a value


Excel VBA provide options on how to pass value from worksheet to worksheet or from workbook to another workbook.

To optimize or make the VBA code run faster is to make the worksheet interaction lesser.

Recording an Excel VBA macro to copy and paste a value will have a similar output to the code below.

Sub Macro1()
'
' Macro1 Macro
' 
'
    Range("A2").Select
    Selection.Copy

    Sheets("Sheet2").Select
    Range("A3").Select
    ActiveSheet.Paste

End Sub

what the code does is to select the cell on the active sheet for copying and select another worksheet and select the cell where the value will be placed and paste the copied cell value.

Steps are:
a. Select the cell and copy the value
b. Select the worksheet where the value is to be copied
c. Next step, is select the cell on the selected worksheet
d. Paste the value on the cell

Steps are absolutely fine, if it works as expected. But if you are copying hundreds or thousands of cells. It will be a waste of time and the computer will be very slow.

Another way to copy and paste a value, or reference a cell value is using the code below:

Sub cells_copy()

       
     Sheets("Sheet1").Range("A1:A25").Copy
     Sheets("Sheet2").Range("B1").Resize.PasteSpecial Paste:=xlPasteAllExceptBorders

End Sub

Code above uses copy and paste method, but ultimately waste clipboard memory.

Code below is quite optimized since the value is just reference to the cell and no clipboard memory resources are used, and selecting worksheet is not needed also.

Sub cells_copying()

Worksheets("Sheet3").Range("C1:C25").Resize.Value = Worksheets("Sheet1").Range("b1:b25").Resize.Value


End Sub

Mileage will always vary, of course any code optimized or not optimized is good, as long as it deliver the expected results.


Hope it helps.

Cheers..till next time!

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided. Why would you need a command line tool if there’s a GUI to check? If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username. If you have remote computers, you need to delegate someone in the remote office or location to check. Or you can just write a batch file or script to automate the task. Here’s the code below on how get computer model, manufacturer and the username. Open an elevated command prompt and type:     wmic computersystem get "Model","Manufacturer", "Name", "UserName" Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.

If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
