I have been wondering what the purpose of the Formula property is in VBA since we can get the exact same output in Excel using the same code without the the said property.
For example :
Sub myformula()
Range("f3").Formula = "=sum(b6+h9)"
End Sub
produces the same results as
Sub myformula()
Range("f3") = "=sum(b6+h9)"
End Sub
Is there a specific scenario in which using this property becomes important and just typing out the formula as a value might not work?

So I'm attempting to filter a large section of data in a spreadsheet with checkboxes. So far around 80 individual checkboxes. I'm wondering if there is anyway to refer to the checkbox (or any other control) name within the sub, as a specific reference, i.e. thiscontrol.name. At present the first checkbox reads:
Private Sub_F1_Click()
StringVariableForLaterUse ="F1"
If F1.Value = True Then
'Display Data Relevant to F1
End If
End
I'm wondering if I can use
StringVariableForLaterUse = ThisControl.Name
and
If ThisControl.Value = True Then
I'd then be able to replicate this a further 78 times. Currently pure laziness factor, however I want my Subs to be self sufficient as possible. Any thoughts folks?
You can never use a string like an object... But, for an ActiveXcheck box, use the next workaround code.
Public chk1 As Shape
Private Sub CheckBox1_Click()
Set chk1 = ActiveSheet.Shapes(CheckBox1.Name)
MsgBox chk1.OLEFormat.Object.Object.value
End Sub
You can use now chk1 in another Sub inside the sheet module.
You can also refer to it from a module Sub, referencing the sheet, too:
Sub testSheetChk()
Debug.Print Worksheets("Sheet Name").chk1.OLEFormat.Object.Object.value
End Sub
But, this will work only after you firstly run (once) the click event, in order to alocate a value to the object variable.
Hey I am doing a reporting generate program.
I need to update certain part of some TextBox in PowerPoint (such as date).
I tried to do it with vba, but it turns out to be very complicated because once I updated the text content, I would have to re-setup all the format.
Is there an convenient way to update certain part of the TextBox without have to re-setting up all the formatting?
As you suspected, the Replace method will do what you want.
Example:
Sub ReplaceText(oRng As TextRange, sReplaceWhat As String, sWithWhat As String)
With oRng
.Characters.Replace sReplaceWhat, sWithWhat
End With
End Sub
And to test it
Sub Test()
With ActivePresentation.Slides(1).Shapes(1)
Call ReplaceText(.TextFrame.TextRange, "text", "newtext")
End With
End Sub
I've seen many users asking questions trying to change the colors of cells using User-defined functions. I was always under the impression that it was not possible to do so. My understanding was that a user-defined function cannot change any properties of a cell except the value of the cell that contains the formula. Subs are what change cells themselves.
However, when playing around with some code to test this, I found that it's not always the case.
Using the simple code:
Function ColorCell(rng As Range)
If rng.Value = 1 Then
ColorCell = False
Else
ColorCell = True
rng.Interior.ColorIndex = 3
End If
End Function
If I enter the function into a cell, I achieve expected results, no cells change colors. However, if I use the Formulas > Insert Function button and navigate to my formula to insert it this way, it does color the targeted cells.
How is this possible, and why did the function behave differently when entered in different ways?
EDIT: this was tested using Excel 2007
use this code...just replace sheet name and try
Sheets("sheet_name").range(j:j).clear
for j=2 to 15
if Sheets("sheet_name").Cells(j, 1).value=1 then
else
Sheets("sheet_name").Cells(j, 1).Interior.ColorIndex = 3
next j
As we all find out sooner or later, in user functions you can't access subs that change things in your spreadsheet directly.
But try this:
Dim ColorMeTarget As Range, ColorMeVal As Long
Public Function ColorMe(ByVal TargetRange As Range, ByVal ColVal As Long)
Set ColorMeTarget = TargetRange
ColorMeVal = ColVal
ColorMe = ColVal
End Function
Public Sub ColorMeSub()
Application.OnTime Now + TimeValue("00:00:05"), "ColorMeSub"
If ColorMeTarget.Interior.Color <> ColorMeVal Then ColorMeTarget.Interior.Color = ColorMeVal
End Sub
If you run the sub first, it will constantly scan the static variables ColorMeTarget and ColorMeVal to see if there is a change. The function ColorMe will set these values. Some additional code is needed in case ColorMeTarget is not yet initialized.
If you get smarter, you could have the function first check to see if there is indeed a change and add the new coloring requests to a stack. Your reoccurring sub can then 'catch up', especially if you have many functions like this.
You can then even have all kinds of additional controls added to your function/macro--EVEN STUFF NOT COVERED BY THE LATEST VERSIONS OF 'CONDITIONAL FORMATING'!!! YAY!!!!
Something to try: In some of my automated macros, I am able to set OnTime through a function but cannot make it work here. It would be cleaner to have the function set the OnTime and not have a reoccuring sub that needs initializing.
I use Worksheet_Change event to detect value change in working range. Example.I want to do something when range A1:A5 has been change. I use below event.
Sub Worksheet_Change(ByVal Target As Range)
If Not Intersect(Target, Range(<Your working range>)) Is Nothing Then 'Define range that you want to do
'Statement here
...
End If
End Sub
When the range value has been change. It will execute your code.
And other way. Use Conditional Formatting.
could also try the non-script method of auto-coloring a cell based on the condition of the cell (aka Conditional Formatting):
Kindly I need help after trying for hours myself.
I have this code to run a code base on a cell value change, but works only if I type myself the change.
I need to be automatic with the function I have inside the cell, but I can get it right.
This is the code I have now that works well manually:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$1" Then
Application.EnableEvents = False
Range("D10").Select
Selection.ClearContents
Application.EnableEvents = True
End If
End Sub
Anything that I should add to make it automatic with the formula inside?
This is a tricky one since there is no built in worksheet event that triggers when a particular cell has a value change due to a formula. There is, however, a Worksheet.Calculate event that could be used.
First we make a global string variable. This is a variable that is declared outside of a subroutine or function. It will hold it's value between executions of subroutines and functions. So we will declare it, and then set it to the value of A1 when A1 is changed.
Dim lastValue As String
Private Sub Worksheet_Calculate()
If Range("A1").Value <> lastValue Then
lastValue = Range("A1").Value
Range("D10").ClearContents
End If
End Sub
lastValue here is our Global that will hold the last known value of A1. When worksheet.calculate is triggered it will compare that value against A1 to see if it's changed, if it is then it executes your code to clear the contents of D1
Instead of a Global you could also just stick that last known value of A1 into a Cell somewhere too. Then do you comparison to that. The advantage of using a cell over a global variable, is that the cell value will hold it's value even if you close and reopen the sheet. So, depending on your needs, it may be a better option:
Private Sub Worksheet_Calculate()
lastValue = Range("Z10").value
If Range("A1").Value <> lastValue Then
Range("Z10").value = Range("A1").Value
Range("D10").ClearContents
End If
End Sub
Where Range Z10 is the spot that holds the last known value.
Lastly I reduced your code to clear contents of D10 to a single line. Anytime you see Something.Select and then in the next line see Selection.DoSomething you can just get rid of that Select/Selection bit. Selecting a cell is generally something that only a human needs to do to interact with the sheet. VBA can do whatever it likes to cells without have to Select them.
I cannot figure out the best way to do the following problem. Basically my macro (excel, VB) is checking several (100+) worksheets for correct values, if wrong value is found, I want it to stop, give me a warning, then I could have a look into the reason why the value is wrong, correct it manually and then I want to resume the macro, or remember the last value checked so if I return, it remembers where to continue (resume).
My current problem is that it finds the wrong value, then I can either make it stop so I check the problem, or it goes through all the sheets and then I have to remember which sheets had the wrong value.
What I thought of is make a list where the name of sheet is added every time a wrong value is found. The problem is that usually there is more than 1 wrong value in the same sheet if there is a wrong value at all and this added the same sheet name several times to the list. Another problem with that is that I cannot correct the values straight away.
I'm very inexperienced with programming and so would appreciate your idea on how to best approach this problem (I don't want to spend a long time on coding something which wouldn't be efficient for such a "simple" problem).
When the error is found (I'm assuming you've already been able to identify this), you can use the Application.InputBox function to prompt you for a new value.
For example, if rng is a Range variable that represents the cell being checked, and you have some logic to determine where the error happens, then you can just do:
rng.Value = Application.InputBox("Please update the value in " & rng.Address, "Error!", rng.Value)
The inputbox function effectively halts execution of the procedure, while waiting for input from the user.
If InputBox isn't robust enough, then you can create a custom UserForm to do the same sort of thing. But for modifying single range values, one at a time, the InputBox is probably the easiest to implement.
I believe you can handle this task by using one or two static local variables in your macro. A variable declared with "static" rather than "dim" will remember its value from the last time that procedure was run. This can hold where you left off so you can resume from there.
One thing that could be a problem with this solution would be if the macro gets recompiled. That would probably cause VBA to clear the value that the static variable was holding. Just doing a data edit in Excel should not cause a recompile, but you will want to watch for this case, just to make sure it doesn't come up. It almost certainly will if you edit any code between executions.
Create a public variable that stores the cell address of the last checked cell and use a conditional statement to see if it's "mid-macro" for want of a better phrase. here is a very crude example...
Public lastCellChecked As String
Sub Check_Someting()
Dim cell As Excel.Range
Dim WS As Excel.Worksheet
If Not lastCellChecked = vbNullString Then Set cell = Evaluate(lastCellChecked)
'// Rest of code...
'// Some loop here I'm assuming...
lastCellChecked = "'" & WS.Name & "'!" & cell.Address
If cell.Value > 10 Then Exit Sub '// Lets assume this is classed as an error
'// Rest of loop here...
lastCellChecked = vbNullString
End Sub
The best way to do this is to create a userform and as mentioned by prior users create a public variable. When the program finds an error store the cell and initiate the userform. Your code will stop on the userform. When you're done checking the problem have a button on the userform that you can click to continue checking. Your loop can be something like the below.
public y as integer
sub temp1 ()
rw1= range("a500000").end(xlup).row 'any method to create a range will do
if y = null then y=1
for x = y to rw1
cells(x,1).select
'check for the problem your looking for
if errorX=true then
userform1.show
y = activecell.row
exit sub
end if
next x
end sub
What about inserting a button (on the sheet or in a menubar) for stopping?
Insert the code below:
'This at the top of the module
Public mStop As Boolean
'This in the module
Sub MyBreak()
mStop = True
End Sub
'This is your macro
Sub YourMacro()
'This at the top of your code
mStop = False
'Your code
'...
'This code where you want to break
DoEvents '<<<< This makes possible the stop
If mStop Then
mCont = MsgBox("Do you want to continue?", vbYesNo)
If mCont = vbNo Then
Exit Sub
Else
mStop = False
End If
End If
'Your code
'...
End Sub
Now you need to create a button and link it to the macro called "MyBreak".
