How to create a log in form using range - excel

i am having a problem selecting the range
this is for vba
Dim i As Long
Dim LastRow As Long
LastRow = Sheets("admin").Range("a" & Rows.Count).End(xlUp).Row
For i = 2 To LastRow
If Sheets("admin").Cells(i, "A").Value = (Me.TextBox1) Then
Sheets("admin").Select
Me.TextBox1.Value = Sheets("admin").Cells(i, "A2").Value
Sheets("Interface").Select
Sheets("Menu").Visible = True
ActiveWindow.SelectedSheets.Visible = False
Sheets("Menu").Select
Sheet6.User.Enabled = True
End If
Next i
i am expecting to have each role to access a certain sheets

I believe the following might help you, I've removed the unnecessary select statement and altered your code ever so slightly:
Sub Example()
Dim i As Long
Dim LastRow As Long
LastRow = Sheets("admin").Cells(Rows.count, "A").End(xlUp).Row
For i = 2 To LastRow
If Sheets("admin").Cells(i, "A").Value = (Me.TextBox1) Then
Me.TextBox1.Value = Sheets("admin").Cells(i, "B").Value
'check if you want the value on column B, amend as required
'it doesn't make sense to check whether Column A = Me.TextBox1 and then pass the
'value from TextBox1 to Column A again...
Sheets("Interface").Visible = xlSheetHidden 'or xlSheetVeryHidden
Sheets("Menu").Visible = True
Sheets("Menu").Select
Sheet6.User.Enabled = True
End If
Next i
End Sub

Loop through and copy paste values without repetition if conditions are met

Im trying to create a table that pulls data from my raw data if certain conditions are met. The code I currently have does not seem to be working.
Public Sub insert_rows()
Dim datasheet As Worksheet
Dim datasheet2 As Worksheet
Dim r As Long
Dim tableA As ListObject
Set tableA = Worksheets(Sheet7).ListObject(Preventable)
Set datasheet = Worksheets(Sheet7)
Set datasheet2 = Worksheets("Data")
With datasheet2
nr = Cells(Rows.Count, 1).End(x1up).Row
For r = 1 To nr
If Cells(r, 17) = "Y" Then
Cells(r, 16).Copy Destination:=Sheets("Sheet7").Range("B4")
End If
Next
End With
End Sub
Basically I have several worksheets and need to pull data from one of them to add to this table in another worksheet. My condition is if the Column in the raw data worksheet contains "Y", then pull cell values into the table of the other worksheet. An image below is an example of the data I want to copy and paste over:
As you can see, they are string values separated by "," and can contain duplicates.
I only want to add just the unique entries into the new table; with no repetition of cells. Anyway I could modify this code to suit those conditions?
You could try something like this:
Public Sub insert_rows()
Dim datasheet As Worksheet
Dim datasheet2 As Worksheet
Dim r As Long, i As Long, nr As Long
Dim tableStartingRow As Long, currenttableitem As Long
Dim stringvalues As Variant
Dim stringseparator As String
Dim valueexists As Boolean
tableStartingRow = 4
stringseparator = ","
Set datasheet = Worksheets("Sheet7")
Set datasheet2 = Worksheets("Data")
With datasheet
currenttableitem = .Cells(.Rows.Count, 2).End(xlUp).Row
End With
With datasheet2
nr = .Cells(.Rows.Count, 16).End(xlUp).Row
For r = 1 To nr
If .Cells(r, 17) = "Y" Then
If InStr(.Cells(r, 16), stringseparator) > 0 Then 'If value contains comma
stringvalues = Split(.Cells(r, 16), stringseparator)
For i = LBound(stringvalues) To UBound(stringvalues)
valueexists = False 'Reset boolean
For x = tableStartingRow To currenttableitem
If datasheet.Range("B" & x).Value = Trim(stringvalues(i)) Then
valueexists = True
Exit For
End If
Next x
If Not valueexists Then
currenttableitem = currenttableitem + 1
datasheet.Range("B" & currenttableitem).Value = Trim(stringvalues(i))
End If
Next i
Else
valueexists = False 'Reset boolean
For x = tableStartingRow To currenttableitem
If datasheet.Range("B" & x).Value = .Cells(r, 16).Value Then
valueexists = True
Exit For
End If
Next x
If Not valueexists Then
currenttableitem = currenttableitem + 1
datasheet.Range("B" & currenttableitem).Value = .Cells(r, 16).Value
End If
End If
End If
Next
End With
End Sub
This code will check each value of the cells and will split the contents by ",". Then compare with the content of the table to see if this value is already in there. In case it is not, it will be added, otherwise omitted.
Also, I notice the use of the Cells inside of a With statement. That was making a reference to the active worksheet. To make reference to the item in the With statement, you need to use .Cells
I hope this will help.

Looping through a range to find a value

I have a worksheet that has columns 1-8, rows 3 through the last row. I would like to loop through each cell to find out if a value of 1 is present. If it is then that row is copied and inserted for each value of 1, additionally that new row will have a text inserted in cell (13,row) then moved to the next row. This is as far as I got....thanks!
Sub Workcenter()
Application.ScreenUpdating = False
On Error Resume Next
Application.DisplayAlerts = False
On Error GoTo 0
Dim Test As Worksheet
Set TS = Worksheets("Test")
Application.DisplayAlerts = True
For k = 1 To 8
For j = 4 To TS.Cells(Rows.Count, k).End(xlUp).Row
If TS.Cells(j, k).Value = 1 Then TS.Cells.Activate
'TS.Cells.Activate.Row.Select
Rows(ActiveCell.Row).Select
Selection.Copy
Selection.Insert Shift:=xlDown
'ShopOrderNumRow = j
Next j
Next k
End Sub
Will try giving some example knowing that I still don't understand how the inserting is occurring for each cell of a row.
Providing more detail, or example of before/after in your post may help.
As for an example, since you're marking only a single cell in each row, I would suggest Find() for value of 1 to determine if you need to write to that specific cell.
'untested code
sub test()
toggle false
dim rowNum as long
for rowNum = firstRow to lastRow Step 1
with sheets(1)
with .range(.cells(rowNum,1),.cells(rowNum,8))
dim foundCell as range
set foundCell = .find(1)
if not foundCell is nothing then .cells(rowNum,13).value = "text"
end with
end with
next iterator
toggle true
end sub
private sub toggle(val as boolean)
with application
.screenupdating = val
.enableevents = val
end with
end sub
Edit1: Looks like countif() may be the saviour here.
Edit2: Tested code input (untested code part of Edit1)
Sub test()
Dim lastRow As Long: lastRow = 10
Dim firstRow As Long: firstRow = 1
toggle False
Dim rowNum As Long
For rowNum = lastRow To firstRow Step -1
With Sheets(1)
Dim countRange As Range
Set countRange = .Range(.Cells(rowNum, 1), .Cells(rowNum, 8))
Dim countOfOnes As Long
countOfOnes = Application.CountIf(countRange, 1)
If countOfOnes > 0 Then
With .Rows(rowNum)
.Copy
.Offset(1).Resize(countOfOnes).Insert Shift:=xlDown
End With
.Cells(rowNum, 13).Value = "text"
End If
End With
Next rowNum
toggle True
End Sub
Private Sub toggle(val As Boolean)
With Application
.ScreenUpdating = val
.EnableEvents = val
End With
End Sub

Excel VBA - Delete empty columns between two used ranges

I would like to delete all empty columns between 2 used ranges, based on the screenshot:
However, these two used ranges may have varying column length, thus the empty columns are not always Columns D to K.
Here is my code:
Sub MyColumns()
Application.ScreenUpdating = False
Application.DisplayAlerts = False
Workbooks.Open ("BOOK2.xlsx")
Workbooks("BOOK2.xlsx").Activate
Workbooks("BOOK2.xlsx").Sheets(1).Activate
Workbooks("BOOK2.xlsx").Sheets(1).Cells(1, 4).Value = "NON-EMPTY"
Dim finalfilledcolumn As Long
finalfilledcolumn = Workbooks("BOOK2.xlsx").Sheets(1).Cells(1, Columns.Count).End(xlToLeft).Column
Dim iCol As Long
Dim i As Long
iCol = firstfilledcolumn + 1
'Loop to delete empty columns
For i = 1 To firstfilledcolumn + 1
Columns(iCol).EntireColumn.Delete
Next i
Workbooks("BOOK2.xlsx").Close SaveChanges:=True
MsgBox "DONE!"
Application.ScreenUpdating = True
Application.DisplayAlerts = True
End Sub
However, the empty columns still remain.
Do note that the last filled column for the first used range, Place = "USA", Price = "110" and Category = "Mechanical" may not be fixed at Column C, but could go to Column D, E, etc.
Many thanks!
Please, try the next way:
Sub deleteEmptyColumn()
Dim sh As Worksheet, lastCol As Long, rngColDel As Range, i As Long
Set sh = ActiveSheet 'use here your necessary sheet, having the workbook open
'if not open, you can handle this part...
lastCol = sh.cells(1, sh.Columns.count).End(xlToLeft).column
For i = 1 To lastCol
If WorksheetFunction.CountA(sh.Columns(i)) = 0 Then
If rngColDel Is Nothing Then
Set rngColDel = sh.cells(1, i)
Else
Set rngColDel = Union(rngColDel, sh.cells(1, i))
End If
End If
Next i
If Not rngColDel Is Nothing Then rngColDel.EntireColumn.Delete
End Sub
Try this ..
Dim rng As Range, i As Long
Set rng = Workbooks("BOOK2.xlsx").Sheets(1).UsedRange
For i = rng.Columns.Count To 1 Step -1
If WorksheetFunction.CountA(rng.Columns(i)) = 0 Then
rng.Columns(i).EntireColumn.Delete
End If
Next i

Output Range same as input range

I have some history working with VBA, but can't seem to find the solution to this problem. I found an iteration process to select a cell, do a process, and then select the next cell and do the process again, until NULL. I am having a problem outputting each of the processes solutions into the next column. Here is what I have:
Sub Name ()
Dim X As Integer
Dim MyString as String
Application.ScreenUpdating = False
NumRows = Range("D2", Range("D2").End(xlDown)).Rows.Count
Range("D2").Select
For X = 1 To NumRows
MyString = ActiveCell.Value
MyString = Right(MyString, Len(MyString)-6)
Range("I2 to I#").Value = MyString
ActiveCell.Offset(1,0).Select
Next X
End Sub
Range("I2 to I#").Value = MyString is the line that I need help with. I need it to increment to I3, I4, I5, etc. until it reaches NumRows count.
When working with Cells the best way to loop through them is For Each Cell in Range so taking this and as comments told you to avoid selecting, this should help you:
Option Explicit
Sub Name()
Dim C As Range, MyRange As Range
Dim LastRow As Long
Application.ScreenUpdating = False
With ThisWorkbook.Sheets("MySheet") 'Change MySheet for your working sheet name
LastRow = .Cells(.Rows.Count, "D").End(xlUp).Row 'last row on column D
Set MyRange = .Range("D2:D" & LastRow) 'declare your working range
For Each C In MyRange
If Not C = vbNullString Then .Cells(C.Row, "I") = Right(C, Len(C) - 6)
Next C
End With
Application.ScreenUpdating = True
End Sub
Another solution is Do Until. You could use this method if you dont have empty cells in the middle of your data.
Option Explicit
Sub Test()
Dim StartingPoint As Long
StartingPoint = 2 'Set the line to begin
With ThisWorkbook.Worksheets("Sheet1") 'Set the worksheet
Do Until .Cells(StartingPoint, "D").Value = "" 'Repeat the process until you find empty cell
.Cells(StartingPoint, "I").Value = Right(.Cells(StartingPoint, "D").Value, Len(.Cells(StartingPoint, "D").Value) - 6)
StartingPoint = StartingPoint + 1
Loop
End With
End Sub

How to add a step function within a dictionary macro

I am new to VBA and I have been using the great help within this site, to create a macro to take a list of numbers from one sheet (Sheet 14), remove the duplicates and paste within another sheet (Sheet 2).
I am hoping to take this further by rather than pasting the cells one after another I am looking to have the list pasted in alternate rows i.e D10, D12, D14 etc.
I have tried various methods from within this site, however to no avail. I have used different types of "Step" functions but I am struggling to incorporate this within the below coding.
Any help is much appreciated!
Below is what I have at the moment:
Sub RUN()
Application.ScreenUpdating = False
Dim lastRow As Long
Dim i As Long
Dim dictionary As Object
Set dictionary = CreateObject("scripting.dictionary")
Sheet14.Activate
lastRow = Sheet14.Cells(Rows.Count, "F").End(xlUp).Row
On Error Resume Next
For i = 3 To lastRow
If Len(Cells(i, "F")) <> 0 Then
dictionary.Add Cells(i, "F").Value, 1
End If
Next
Sheet2.Range("d10").Resize(dictionary.Count).Value = _
Application.Transpose(dictionary.keys)
Application.ScreenUpdating = True
MsgBox dictionary.Count & " RUN TEMPLATES."
End Sub
Here's one approach (BTW, I wouldn't call a macro RUN):
Sub ListUniques()
Dim lastRow As Long
Dim i As Long
Dim dictionary As Object
Dim vKeys
Application.ScreenUpdating = False
Set dictionary = CreateObject("scripting.dictionary")
With Sheet14
lastRow = .Cells(.Rows.Count, "F").End(xlUp).Row
For i = 3 To lastRow
If Len(.Cells(i, "F")) <> 0 Then
dictionary(.Cells(i, "F").Value) = 1
End If
Next
End With
vKeys = dictionary.keys
For i = LBound(vKeys) To UBound(vKeys)
Sheet2.Range("d10").Offset(2 * i).Value = vKeys(i)
Next i
Application.ScreenUpdating = True
MsgBox dictionary.Count & " RUN TEMPLATES."
End Sub
