Right now I am writing a macro with a defult action if an arry is empty. Unfortunatly the way I wanted to do it will not work becuse it can't recognize the difference between one entry in the array and no entries:
If LBound(array) = UBound(array) Then
I have a range varable (say productxrange), is there a way to determin if that range is empty?
View 4 Replies View RelatedHow can determine if a range is empty without looping it till the first value is found? On a 5x5 range a for loop is not that bad but what if its the whole worksheet? Is there a fast way to do this?

x = Cells(Row, Column).Value

How can I determine that the cell is blank and not actually 0 ?
This will probably turn out to be a really quick one: I've got some named ranges I'm working with that in of themselves use Offset to automatically expand a list.
View 7 Replies View RelatedI have an excel document with hundreds of columns. Each column should not be empty; they must have at least one value. Right now I'm applying a filter and going through each column one by one to make sure that it is not empty. How can I perform this check without having to go through each column one by one?

2. In column B i have the formula that references the corresponding cell in column A in the same row i.e. B1 "=(A1={1;3;5;7;8;10;12})"
Problem: This formula works only when the value in column A equals "1"...i need it to work when it equals any of the identified numbers in the set.
I have an array with an ubound of 10,000 because I will be loading a different amount of numbers each time I run the macro. Is there a way to tell the amount of digits filled inside the array if it is less than 10,000?
View 4 Replies View Related1 workbook, 2 worksheets (or tabs). On tab 1, I want a formula/alert that tells the user if any duplicate values exist in Column A of tab 2
Tab 2, Column A, has Unique ID's (6 digit numeric values)
The user manually inputs the ID's on new rows in Column A
Row 1 is reserved and in use for something else
Row 2 is my header, so cell A2 says "ID"
Row 3-623 currently contain unique ID's
When the user inputs a new ID into cell A624, then they return to Tab 1, I want my formula/alert on Tab 1 to tell the user that they have duplicates in Column A of tab 2. I know the Conditional Formatting, but if the user copies in 100 new values, they won't necessarily see the highlighted cells. My tab 1 is my "checks and balances" and the last place the user is suppposed to look to ensure that they haven't created any duplicate ID's. If the user sees a warning message that says duplicates exist, then I'll tell them that they need to look at column A (for cells that have been conditionally highlighted).
One issue that I'm running into with the conditional highlighting is that I want cells A3:A1048576 to already have the conditional formatting - this way when the user inserts a value into Cell A624, then A625, etc they conditional formatting is already there. Right now with data in cells A3:A623, cells A624:A1048576 are all highlighted with the Red/Bold Red Font (which is okay I guess), but ideally it would be nice to not count 2+ empty cells as duplicates and I'll have to have my formula on Tab 1 not include the blank cells.
I DO NOT want to use the Remove Duplicates feature of Excel 2010. If I remove them I could be removing data in columns B, C, D, etc that belong to the Unique ID. I just need the user to be told in Tab 1 that they DO have duplicates and I'll train the user how to research this and fix it.
The reason I want to look for duplicates in the entire Column A is because the list of Unique ID's will grow over time.
I have an array of variants..
lvarArrSource = Array(12, "=F", 2, 3, 4, 5, 11, 6, 7, 8, 9, 10, "123", "F", "F", "F", "F", 11, "F", "NR", "F")
which i am using to map columns between spreadsheets. The basic numeric entries refer to columns to copy. But I want to make the routine smarter with the strings.
If array(x) = 12 (For example) Then
Do something
End If
If left(array(x),1) = "=" Then
Do something Else
End If
If array(x) Is String literal (e.g "xyz" Or "123") Then
Do a third thing
End If
i cant find a typeof or isstring kind of function. Isnumeric works ok for some values but quoted numbers (eg "123") return true (which isnt what i want). I have tried the left(string,1) = """ but excel seems to hide the quotes.
If I have say several hundred elements stored in an indexed array and I want to clear them each time the sub or function holding them is called, is there a way to erase the contents of the entire array without having to loop through each element.
Something like array().clear? Note that each time the sub is called, they are also redimed to some reference.
Secondly, I am struggling to find a solution to something that in PHP, Java and javascript is painfully simple! That is - checking to see if an array contains no elements.
In PHP for example, you can do:
PHP Code:
$arr = array();echo empty($arr)."
";echo (sizeof($arr) == 0)."
";
This will produce the following output:
Code:
1
1
But ... I can't seem to find any equivalent of empty or sizeof in VBA.
I'm trying to write a function that I can pass an array along with the data I want added to that array. The function will resize the array, put the data into it and return the new array. Example:
Function AddNewDataToArray(MyArray As Variant, Arg1 As String, Arg2 As String, Arg3 As String) As Variant
'If no elements have been added
Redim Preserve MyArray(1 To 3, 1 To 1)
'Add the first record of data to the array.
'If there is already data in the array
Redim Preserve MyArray(1 To 3, 1 To UBound(MyArray, 2))
'Add the next record of data to the array
End Function
As 2 dimensional arrays are Base 1, the challenge I have is getting it to resize (redim preserve) the array when it has to add the first record. I thought I could just use an IsArray function to test if there had been any data added. If not, then it would run the following...........
I want to test how many elements are not empty within a variant array.
For example for arrays Arr1 and Arr2 below the answers would be:
- for Arr1 not empty elements=1
- for Arr2 not empty elements=0
Arr1(0)=empty
Arr1(1)=2
Arr1(2)=empty
Arr2(0)=empty
Arr2(1)=empty
Arr2(2)=empty
I've tried with function COUNTA inside VBA but counts even the empty values:
Code:
NotEmptyCells = Application.WorksheetFunction.CountA(Arr1)
Is there another function to count this from an array or alternative way?
I have an array MyArr() in excel.
Its length is from 1 to i where i takes dynamic value from varibable.
Now the problem is MyArr(1 to i) has some empty values.
Like say: if i = 5 then
MyArr(1) = "a"
MyArr(2) = ""
MyArr(3) = "b"
MyArr(4) = ""
MyArr(5) = "c"
How can I get rid of those empty elements so that MyArr() becomes only three elements long and then display them in a range of three cells.

I am trying to populate the 2 tables from excel to word. I will be getting the excel file with tables in various sheets. One sheet consist of 2 tables that will be inserted to one word document. So if there are 2 sheets then I will have the tables inserted in the 2 word document. In the excel sheet I have attached, there are 2 sheets with tables in each of them. I have written the code to copy and paste the table to word doc from (general) range A1:G4 (Table 1) and A9:H18 (Table 2) that has empty rows and columns selected. But there are empty rows and columns inserted since the table range is not same sheetwise. I would like get the empty rows and columns deleted in the word table.
Find the attached sample excel sheet and the word documents.

I have a long range of cells (U3:AX3), all of which are empty save one. Is there a way to search through the range of cells, and return the contents of the one cell that contains text?
I would do this with a series of nested IF statements if there weren't more than 30 of them!
Is a Cell with a formula (like shown below) considered true, or is it empty?
=IF(Scorecard!$B$13,Scorecard!$AD$4,"")
If Scorecard!$B$13 was False...
Would a cell with the above formula be considered?
True or Empty?
If Scorecard!$B$13 was True...
A cell with the above formula would be True.
I am getting values for my excel sheet from another department excel sheet . everything works fine. If there is no values in the rows in the Department sheet, then i need to hide the rows in my sheet. How to code this in VBA. When they add values to the rows then i should make the rows visble here. Kindy give me a sample of vba code to this or suggest me to solve.
View 9 Replies View RelatedIs it possible to make a cell "really" blank/empty based on an If statement? For instance:
=if(a1>10,a1,"")
Has a value_if_false of "". But Excel interprets this a bit differently than a cell that never had anything typed into it.
So if you have a column full of this formula copied down, and hit <control+down arrow>, you will go straight to the bottom and skip over all rows. Whereas if you have a column with values and empty cells alternating and hit <control+down arrow>, you will only skip the empty cells and go to the next value. Excel treats the conditionally empty cells as if they have a value, when it comes to this type of navigation. This holds even if you copy and paste "Values" for the cells over the formulas.
Is there any way to tell Excel to make the cells truly empty?
I need to write a macro which checks cells in one column and if the cell is empty it deletes the whole row (which contains the cell).
I tried this code but it doesn't delete all rows with empty cells:
I am using the following block of code, which cycles through the data and first deletes any cell with "Legal:" in it, and then cycles through again and deletes any row where the cell is blank.
The problem is that within the data, there are some locations where there are two blank rows in a row. When the code runs through, it deletes the FIRST blank row only, not the second. I Need ALL blank rows within the data set to be deleted.
Code:
Sub ModifyNewData()
Dim r As Range, rAll As Range
Dim WS As Worksheet
Dim iLast As Integer
[Code] ........
Also, if there is a way to write looking for blank rows into the first block of code looking for "Legal:" that would be cool too.
If not, just deleting all the blank rows is good. Right now, I have to have the second block of code run twice to get rid of the remaining blank rows.
Using the following code to remove empty rows based on whether a specific range of columns is empty. The code works if the cell has a zero, but not when the cell is blank. An example of the data is attached.
VB:
Public Sub DelRows2()
Dim Cel As Range, searchStr, FirstCell As String
Dim searchRange As Range, DeleteRange As Range
[Code].....
IF cell(some cell) empty AND cell(Diferent cell) not empty then Put Formula in empty cell
Next (to go throught the cells because the range constantly changes with every new report)
in C a string is nothing more than an Array of characters ending with a null character.
in VBA this does not seem to be the case.I am trying to use the BlowFish code from David Midkiff for some encryption, however the code sometimes fails:
When encrypting a string a string of a specific length should be returned. however sometimes one of the characters of the encrypted string is a null character, and the returned encrypted string (with a embedded null character) is causing me problems. I want to check for the null character and if present redo the encryption. But how do I check for the presence of this null character in a unicode (double-byte) string?
Checking with Len(encrypted) gives the correct length (!) but trying to move each (unicode)character into an array fails when using the Mid() function past the null character in the string.
Now I can use
byteArray() = StrConv(unicodetext,vbFromUnicode)
to get the lower byte of each character into an array easily, but how do I do this for both bytes of the unicode characters?
Using an integer array does not work other than through
intArray(j) = CInt(AscW(Mid(Outp, j, 1)))
which fails on the nullstring in my encrypted text.
I have tried with variants but so far no luck. I thought if the string was entered into a variant then I could also address the variant as an array of bytes, but that does not seem to be accepted by VBA.

The above code does not work of course and falls over. I am unsure whether I should try and concatenate with something like this eg "" & arrName(i) = Cells (r,c) or go down a different route.
