Trapping errors are important as users can do marvelous things to mess up you macros. Here you can use either of these 2 statements.
- On Error Resume Next OR
Everybody uses “totals”, right? See the example image. Most users would create the total on row 3.
Sometimes we need to know what the cell contains ie dates, text or formulas before taking a course of action. In this example a message box is displayed. Replace this with a macro should you require another course of action.
Sometimes we need to know the current cell position. This would do the trick.
Sub MyPosition()
To email your current workbook the following code.
Sub Email()
If the contents of the cell cannot fit the column & you want it to fit just nicely, you could use auto fit.
You can hide the Excel application with this macro. This disables the user from using the excel menus. Don't forget to set it back to visible.
Sub HideExcel()
It's a good idea to insert the current date when you save the file so that you can tell if it's the latest version. Of course this is shown under file properties but how many people know where to find it?
Sometimes when you run a macro, the screen flickers a lot due to the screen updating itself. This slows the macro done especially when the macro has a lot of work to do. You need to include the statement as shown below.
You can select the first sheet of the workbook without knowing the name of the sheet by referring to it by the index.
Sub FirstSheet()
Ever had a macro running perfectly one day and the next day errors keep on popping up even though you never made changes to that macro? This is no fault of yours.
It is always a good idea to insert the file name & path and include it in the print range so that you will know the filename & it's location when you need to find the file.
When you need place your text on an exact spot, (for instance when you need to print on pre-printed forms) adjusting the row height & column width can be a big headache coz when you adjust, all other text will move.
When you need to get input from users, you can use input boxes. This macro will ask for the user's name and will display a message "Hello" plus the user's name.
Everybody knows how to ride a mouse (er... move a mouse). Sometimes the keyboard is faster. Well here's a list of controls.
Page Down = To move 1 page down
Unable to sort your dates correctly? If the dates are entered as a text (eg key in as '1/4/2010) then sorting would give you undesired results. You could use...
Sometimes we have many sheets or sheets with long names & we cannot view them all. You can select which sheet to go to by using this macro.
Sub Go2sheet()
Using Excel functions in VBA is almost the same as using them in a spreadsheet. For example to round an amount to 2 decimal places in a spreadsheet would be;
Killing or deleting files is easy. However the files must not be in used.
Equally simple. Just like adjusting columns, point between the row headings (That's the numbers on the left of the rows) the pointer will turn into a double arrow head.
Do you want excel to use the system date? Use this formula =today() and presto you can see the system date. Cool huh? But if you just want the system date without using the formula just press ctrl : and Excel will insert the system date.
Entering data in rows & column can be pretty tedious especially when you have wide columns and the great number of columns. Excel has a data form feature that makes data entry a breeze.
Creating function is useful as complicated formulas can be made easier in code than in a spread sheet. Formulas can be protected so that users cannot see or modify them.
Lets say you need to total numbers that are not in a range, example a1, a5, a10. Well normally the formula would be =a1+a5+a10. If you have 10 cells to total up that would be slow coz you need to type in "+".
To get the current cell address (or current range) to perhaps incorporate into your formula, you could use the following code.
Sub MyAddress()
Sometimes you may want to put a line of text on the next row and not let it continue on the first row. See this example in a message box.
Sub TwoLines()
This is a simple job. Don't sweat it. When you point between the column headings (That's the Alphabets at the top of the columns A, B, C .... etc) the pointer will turn into a double arrow head.
When you need to centre text across cell, the most common method used would be the merge & centre tool. However merging cells could cause other problems when selecting a range or when trying to perform a copy and paste.
Let's say your numbers need to be 4 digits long. 1 to be shown as 0001, 2 as 0002 and so forth. Click Format/Cells/Number/Custom go to the type text box and type in 0000 & click ok.
Need to draw tables? If you noticed your formatting tool bar, the border icon has pretty limited border styles. Where the heck do you go to if you want some fancy borders with colours? It's actually under our nose.
There are times you need to highlight duplicate data in your worksheet. This macro does the trick.
Sub DupsRed()
To delete empty rows in a selected range we can use the following macro. The macro here uses the For Next Loop. First the macro counts the rows in a selected range to determine the when the macro should stop. The For Next statement acts as a counter.
For those who may not have time to format or simple have got an awful sense of colour selection, you could use Excel's Auto Format. First select your range, Click Format / Auto Format and...
There are lots of short cuts in Excel. Like I always say to my students, when in doubt, Right Click. Whenever you point & right click at an object, a menu associated with the object will pop up.
An active cell is the current cell that is selected. This term is used in many macros. This can be used as a marker.
To hide your worksheet from users you can use the following code.
Sub HideSheet()
To insert rows required by a user is easy. Here the input box is used so that a user can define the number of rows required.
Sub InsertRow()
To move a sheet, simply click on the sheet tab & drag to the left or right.
To rename a sheet, double click on the sheet tab & type in the new name.
To delete all the range names in your workbook, this macro will do the trick.
Sub DeleteNames()
What if you want your dates to show Sunday, 25 December? Simple, select the cell with the date, click Format/Cells/Number/Custom (If you are too lazy just press Ctrl 1 remember?), go to the TYPE text box and...
There's more to it than just copy (Edit/Copy or ctrl C) & paste (Edit/Paste or ctrl V). You can copy and control exactly what you want to paste. Example you need to copy a total (where you used a formula) and when you pasted it get an error because of the formula.
To use a counter in your macro, just assign any cell to retain the value. In this example the cell A1 is chosen. Each time the macro is run, it adds the value 1 to the cell A1.
Getting wrong date formats when entering a date? Let's say you entered 1st April 2010 in excel, but upon pressing the Enter key the date shows 4th January 2010 instead.
There are times you need include numbers or dates together with your text. Typing it in doesn't do much if the numbers keep on changing because it's a formula and you want it linked to your text.
When your row height is much higher the your font, you will notice the contents will be anchored to the bottom of the cell. And that's a bit ugly. What if I want it to be in the centre instead. No problem.
Again Office 2000 applications tries to save space buy cramping both toolbars into one row. Land is an expensive commodity these days!!! So, just point at the light grey vertical line at the begining of the Formatting toolbar until you see a crossed double arrow head.
Sometimes you may want to close all files without saving. Doing it manually is a hassle with the question "Do you wanna save?"
Sub CloseAll()
To populate a combobox or a listbox is the same. You could add from the code or even from a range of cells in your spreadsheet. To add from the code, just add this line to your code.
If you're sharing a computer, there's always a smart alec who likes to mess up your toobars. To reset them back to the default style, Right Click any tool bar, Customise, Click the Tool bar tab, select the tool bar you want to reset & click on RESET and presto. It's done.
To specify a macro to go to a specific range you can use the Goto method. Here I have already named a range in my worksheet called "Sales". You may also use an alternative method ie the Range select method.
When you have selected a range, it is sometimes useful to know how many rows or columns you have selected as this information can be used in your macros (for eg when you have reached the end, you will know it is time to stop the macros. This macro will do the trick.
It's a rat race out there sometimes. Short cuts do help & is faster then reaching for the mouse. Especially if your mouse is not working properly (pretty common problem for some of us huh?)
Unable to do a lookup? Entries look the same but lookup returns #N/A error. This is a formatting problem. To overcome this you have a couple of options. One is to copy the data from Excel and paste it to Notepad.
A point to note is, try not to use the For, Next loop because this method is very slow...
Sometimes we inherit files belonging to someone else who has a bad taste in colour, fonts & borders. You want to clear all formats quickly before you get sore eyes. What do you do?
Excel recognises dates whether you use slash ("/") or hyphen ("-"). However if you use full stop (".") Excel would assume the date as a text. Therefore you will not be able to customise the date styles or even perform calculations with the date.
How do you turn on your toolbars? Very simple, point at any tool bar & RIGHT CLICK and select the tool bar that you want to appear. Like I always say, when in doubt...
Making your macros run automatically when opening your workbook. You can either use the Auto Open method or the Workbook Open method. These macros will display the message "Hello" when you open the workbook.
Copy data from a specific range can be done with this macro. Here data is copied from the current sheet to the activecell.
Sub CopyRange()
The menu bars for Office 2000 applications tend to help you save time by displaying the regularly used commands instead of the full list of commands and to display the full list you would have to...
There are times where we import text file into Excel an we get text that are separated. I received an email asking how put these text together. Select across your cells first and run this macro.
There are time you just want to squeeze everything into one cell. Other than adjusting the column width, you could reduce the font size either manually or automatically.
