Using VBA Functions in Excel Worksheet
When evaluating a blank cell, Excel returns two different values from two functions I had expected would return the same value:
Worksheet function: Application.WorksheetFunction.IsNumber(Range(.)) returns FALSE
VBA function: IsNumeric(.) returns TRUE
Why would IsNumeric return TRUE for a value of ""?
Is it possible to create "custom" worksheet functions in VBA in Excel 2007?
I used to do this quite easily in Excel 5. I can't find how to do this in the new version.
This MS article doesn't seem to work for the 2007:
in using VBA Excel and have never use VBA excel before and am totally lost in my problem. Thus, I would GREATLY appreciate a direction or two.
I have 2 worksheets ONE and TWO. Both have the same columns type and column number (approximately 15) with worksheet TWO being the more updated worksheet.
I need to find the rows in worksheet TWO which are not present in worksheet ONE by comparing column A in both worksheets. After which I will copy the whole row from worksheet TWO to worksheet ONE. During the process of comparing column A in both worksheets, I also need to update column C and E of worksheet ONE.
I can do the above without using VBA but I need to create a macro for it to automate the whole process for future uses.
There is an Excel worksheet function "FIND()" I use in cell equations along with MID(), RIGHT() and LEFT().
I have found the MID(), RIGHT() and LEFT() to work in VBA, however I am not having luck with a function like the FIND() in the worksheet functions. Does something like that exist in VBA?
I have a macro that opens a worksheet and at the same time disables the ability to print, save, email, . the information on the worksheet. There is also a button that re-enables these commands on exit.
Problem being some people are closing the worksheet by clicking on the x button in the top right hand corner - leaving these commands disabled.
Is there a way I can use VBA in my existing button code to disable the close worksheet and close excel crosses, ane re-enable them when the button to exit the worksheet is correctly pressed? I can see that it can be done via a form, but I have a worksheet not a form.
Any help or comments on whether this is possible

Consider the following real problem. You want to write a function that is capable of sorting virtually any collection of data that can be stored in an array. This might be an array of strings, or integers, or floats, or even structures. The sorting algorithm can be the same for all. For example, it could be a simple bubble sort algorithm, or the more complex shell or quick sort algorithm. Well use a simple bubble sort for demonstration purposes.
If youre a flash developer you definitely need to know the origins of the trigonometric functions. Ill start by saying that the SIN function is reflection of an angle on the Y-axis, and COS a reflection of an angle on the X-axis. People say that a picture is worth a thousand words, then, take a look for yourself. Enjoy
