If Block is firing both If and Else statements - vb.net

I'm having an issue that I feel should be fairly simple but turns out I can't get it to work. I'm sure it's something that I am doing but I need your expert help. I'm simply cycling through a datatable and checking to see if a value shows up again in a different column of the datatable. For some reason BOTH statements are firing and the else statement is overwriting the If statement.
For i = 0 To length - 1
For j = 0 To length - 1
If Trim(dt.Rows(i)(0)) = Trim(dt.Rows(j)(6)) Then
need_dt.Rows(i)(9) = "COMP"
need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(need_dt.Rows(i)(2), -5), "MM/dd/yy")
Else
need_dt.Rows(i)(9) = "TOP"
need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(need_dt.Rows(i)(2), -16), "MM/dd/yy")
End If
If Year(need_dt.Rows(i)(10)) = 2029 Then need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(Now, 14), "MM/dd/yyyy")
Next
Next

The else statement will be executed on all rows that aren't found. You need to keep the result in a variable and do the action you want at the end. Since the other If statement doesn't use j, you don't need to do it on every j.
For i = 0 To length - 1
Dim isFound As Boolean = False
For j = 0 To length - 1
If Trim(dt.Rows(i)(0)) = Trim(dt.Rows(j)(6)) Then
isFound = True
Exit For
End If
Next
If isFound Then
need_dt.Rows(i)(9) = "COMP"
need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(need_dt.Rows(i)(2), -5), "MM/dd/yy")
Else
need_dt.Rows(i)(9) = "TOP"
need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(need_dt.Rows(i)(2), -16), "MM/dd/yy")
End If
If Year(need_dt.Rows(i)(10)) = 2029 Then need_dt.Rows(i)(10) = Format(resource.AddWorkingDays(Now, 14), "MM/dd/yyyy")
Next

As I understand you want set column number 9 = "COMP" if value of column 0 exists in column 6 of any row.
In this case your problem is -> if last value of column 6 in last row is not equal to value of column 1 - value of column 9 will be overwritten with "TOP"
In your code you need exit from loop after you find equal value.
But I suggest to use little bid more readable approach
For Each row As DataRow in need_dt.Rows
Dim firstColumnValue As String = row.Field(Of String)("0ColumnName").Trim()
Dim is6ColumnContainValue As Func(Of DataRow, Boolean) =
Function(dtRow) dtRow.Field(Of String)("6ColumnName").Trim() = firstColumnValue
Dim isValueFound = need_dt.AsEnumerable().Any(is6ColumnContainValue)
Dim tenthColumnValue AS Date = row.Field(Of Date)("10ColumnName")
Dim workingDaysToAdd As Integer
If IsValueFound = True Then
row.SetField("9ColumnName", "COMP")
workingDaysToAdd = -5
Else
row.SetField("9ColumnName", "COMP")
workingDaysToAdd = -16
End If
If TenthColumnValue.Year = 2029 Then
tenthColumnValue = resource.AddWorkingDays(Date.Now, 14)
Else
tenthColumnValue = resource.AddWorkingDays(tenthColumnValue, workingDaysToAdd)
End If
row.SetField("10ColumnName", tenthColumnValue)
Next
Also suggest to set Option Strict On which give compile time feedback about possible type conversion errors

Searching for String inside another (with interruptions), on Excel

I'm trying to check whether the main string contains the entire substring, even if there are interruptions.
For example:
main string = 12ab34cd,
substring = 1234d
should return a positive, since 1234d is entirely contained in my main string, even though there are extra characters.
Since InStr doesn't take wildcards, I wrote my own VBA using the mid function, which works well if there are extra characters at the start/end, but not with extra characters in the middle.
In the above example, the function I wrote
works if the main string is ab1234dc,
but not if it's 12ab34cd.
Is there a way to accomplish what I'm trying to do using VBA?
Note Both of the methods below are case sensitive. To make them case insensitive, you can either use Ucase (or Lcase) to create phrases with the same case, or you can prefix the routine with the Option Compare Text statement.
Although this can be done with regular expressions, here's a method using Mid and Instr
Option Explicit
Function ssFind(findStr, mainStr) As Boolean
Dim I As Long, J As Long
I = 1: J = 1
Do Until I > Len(findStr)
J = InStr(J, mainStr, Mid(findStr, I, 1))
If J = 0 Then
ssFind = False
Exit Function
End If
I = I + 1: J = J + 1
Loop
ssFind = True
End Function
Actually, you can shorten the code further using Like:
Option Explicit
Function ssFind(findStr, mainStr) As Boolean
Dim I As Long
Dim S As String
For I = 1 To Len(findStr)
S = S & "*" & Mid(findStr, I, 1)
Next I
S = S & "*"
ssFind = mainStr Like S
End Function
Assuming you have 3 columns "SUBSTR","MAIN" and "CHECK" and your "Substring" data range is named "SUBSTR"
Sub check_char()
Dim c As Range
For Each c In Range("SUBSTR")
a = 1
test = ""
For i = 1 To Len(c.Offset(0, 1))
If Mid(c.Offset(0, 1), i, 1) = Mid(c, a, 1) Then
test = test & Mid(c.Offset(0, 1), i, 1)
a = a + 1
End If
Next i
If test = c Then
c.Offset(0, 2) = "MATCH"
Else
c.Offset(0, 2) = "NO MATCH"
End If
Next
End Sub

Do-While loop (VBA) not looping

so I thought this would be a simple logical problem, but for the life of me I cannot find the issue with this code block. I have checked around on Stack for a solution, but all other do/while loop problems appear to be primarily with other languages.
What I am trying to do is simply loop through an array & add a new worksheet for each element in the array that is not null. Pretty simple right? Yet for some reason it simply loops through once and thats it.
Here is the code block:
Dim repNames() As String
Dim x As Integer
x = 25
ReDim repNames(1 To x)
repNames(1) = "Ahern"
repNames(2) = "Castronovo"
repNames(3) = "Glick"
repNames(4) = "Fields"
repNames(5) = "Murphy"
repNames(6) = "Sleeter"
repNames(7) = "Vivian"
repNames(8) = "Walschot"
repNames(9) = "Wilson"
Dim i As Integer
i = 1
Do 'Loop keeps creating only 1 new sheet. Should create 9.
Worksheets.Add.Name = repNames(i)
i = i + 2
Loop While repNames(i) <> Null
I believe the problem is with this line: Loop While repNames(i) <> Null,
but obviously the logical test seems to hold up.
Any help would be hugely appreciated!
As others note, Null is not the comparison you want to make. Testing anything for equivalence with Null will return Null -- even ?Null = Null returns Null, which is why your loop is exiting early. (Note: To test for a Null, you need to use the IsNull function which returns a boolean, but that is NOT how you test for an empty string.)
In VBA, to test for a zero-length string or empty string, you can use either "" or vbNullString constant, or some people use the Len function to check for zero-length.
Rectifying that error, as originally written in your code, your logical test should abort the loop if any item is an empty string, but none of the items are empty strings (at least not in the example data you've provided) so you end up with an infinite loop which will error once i exceeds the number of items in the repNames array.
This would be probably better suited as a For Each loop.
Dim rep as Variant
For Each rep in repNames
Worksheets.Add.Name = rep
Next
If you need to skip empty values, or duplicate values, you can add that logic as needed within the loop:
For Each rep in repNames
If rep <> vbNullString 'only process non-zero-length strings
Worksheets.Add.name = rep
End If
Next
Etc.
Firstly, you should be comparing to vbNullString. This loops multiple times:
' Declare variables
Dim repNames() As String
Dim x As Integer
Dim i As Integer
' Set data
x = 25
ReDim repNames(1 To x)
repNames(1) = "Ahern"
repNames(2) = "Castronovo"
repNames(3) = "Glick"
repNames(4) = "Fields"
repNames(5) = "Murphy"
repNames(6) = "Sleeter"
repNames(7) = "Vivian"
repNames(8) = "Walschot"
repNames(9) = "Wilson"
' Loop through items
i = 1
Do
Worksheets.Add.Name = repNames(i)
i = i + 2
Loop While repNames(i) <> vbNullString
There is one more problem – why i = i + 2 ? In your question you say you wanted the loop to execute 9 times, but using i = i + 2 skips every other item. If you indeed want to loop through every item:
Do
Worksheets.Add.Name = repNames(i)
i = i + 1
Loop While repNames(i) <> vbNullString
Here you go, I have changed the loop conditional, and changed i=i+2 to i=i+1. A regular while loop would be better than a do while encase the first element is empty
Dim repNames()
Dim x As Integer
x = 25
ReDim repNames(1 To x)
repNames(1) = "Ahern"
repNames(2) = "Castronovo"
repNames(3) = "Glick"
repNames(4) = "Fields"
repNames(5) = "Murphy"
repNames(6) = "Sleeter"
repNames(7) = "Vivian"
repNames(8) = "Walschot"
repNames(9) = "Wilson"
Dim i As Integer
i = 1
Do While repNames(i) <> ""
Worksheets.Add.Name = repNames(i)
i = i + 1
Loop

Adding content of a cell into a string variable in VBA. Also, adding cells below it using offset

I have a simple function that is going to pull from a specific Cell (N4). If there are cells below it then it will loop and collect all the content of the cell and separate with comma.
I'm getting #VALUE! error in excel right now and I kind of know where my issue lies but can not figure how to fix it, since I am not that proficient with excel-vba code. I think the issue is with ActiveSheet.Range("N4").Value and the offset part.
I am not sure how to offset then select the value in the text then add it to my string Value.
Any thought on how I can select the content of cell and add to string variable and doing the same when you offset?
Here is my code:
Function pullshit() As String
Dim output As String
Dim counter As Integer
counter = 1
output = ActiveSheet.Range("N4").Value
If Application.offset(N4, counter, 0).Value = "" Then
pullshit = output
Else
While counter <> 0
output = output + ", " + Application.offset(N4, counter, 0).Value
counter = counter + 1
If Application.offset(N4, counter, 0) = "" Then
counter = 0
End If
Wend
pullshit = output
End If
End Function
Offset use is wrong. Try this.
Function pullshit() As String
Dim output As String
Dim counter As Integer
counter = 1
output = ActiveSheet.Range("N4").Value
If Range("N4").Offset(counter, 0).Value = "" Then
pullshit = output
Else
While counter <> 0
output = output + ", " + Range("N4").Offset(counter, 0).Value
counter = counter + 1
If Range("N4").Offset(counter, 0) = "" Then
counter = 0
End If
Wend
pullshit = output
End If
End Function

Run-time error "13": in my VBA excel code

I'm writing a script that will count a numbers of days between few separate dates. I have a data in cell like:
1-In Progress#02-ASSIGNED TO TEAM#22/01/2013 14:54:23,4-On

And for now I get
Run-time error "13"

I would be very grateful for any help.
You are getting that error because of Type Mismatch. dataztekstu is declared as a date and most probably the expression which is being returned by the function funkcjadataztekstu is not a date. You will have to step through it to find what value you are getting in return.
Here is a simple example to replicate that problem
This will give you that error
Option Explicit
Sub Sample()
Dim dt As String
Dim D As Date
dt = "Blah Blah"
D = getdate(dt)
Debug.Print D
End Sub
Function getdate(dd As String)
getdate = dd
End Function
This won't
Option Explicit
Sub Sample()
Dim dt As String
Dim D As Date
dt = "12/12/2014"
D = getdate(dt)
Debug.Print D
End Sub
Function getdate(dd As String)
getdate = dd
End Function
If you change your function to this
Function funkcjadataztekstu(koniectekstu As String)
Dim temp As String
temp = Right(koniectekstu, 19)
temp = Left(temp, 10)
MsgBox temp '<~~ This will tell you if you are getting a valid date in return
funkcjadataztekstu = temp
End Function
Then you can see what that function is returning.
I tried running your code, but it is a little difficult to understand just what it is that you want to do. Part of it is the code in your language, but the code is also hard to read beacuse of the lack of indentation etc. :)
Also, I do not understand how the data in the worksheet looks. I did get it running by guessing, though, and when I did I got the same error you are describing on the second run of the For loop - that was because the koniectekstu string was empty. Not sure if this is your problem, so my solution is a very general.
In order to solve this type of problem:
Use Option Explicit at the top of your code module. This will make you have to declare all variables used in the module, and you will remove many of the problems you have before you run the code. Eg you are declaring a variable status4jest but using a different variable called staus4jest and Excel will not complain unless you use Option Explicit.
Declare return types for your functions.
Format your code so it will be easier to read. Use space before and after statements. Comment everything! You have done some, but make sure a beginner can understand. I will edit you code as an example of indentation.
Debug! Step through your code using F8 and make sure all variables contain what you think they do. You will most likely solve your problem by debugging the code this way.
Ask for help here on specific problems you run into or how to solve specific problems, do not send all the code and ask why it is not working. If you break down your problems into parts and ask separately, you will learn VBA yourself a lot faster.
A specific tip regarding your code: look up the Split function. It can take a string and make an array based on a delimiter - Example: Split(tekstwsadowy, ",") will give you an array of strings, with the text between the commas.
Did I mention Option Explicit? ;)
Anyway, I hope this helps, even if I did not solve the exact error you are getting.

VBA code for Extracting Symbols like "&&","&&-","&-" and numbers into different columns

I am having a sheet which contains range of values like "5670&&2","1281&&-3&-5&&7",... etc. in Column A.
Kindly help me to extract the output in VBA in following way:
For E.g 5670&&2 I require A1 cell contains 5670,B1 cell contains &&,C1 cell contains 2.
For E.g 1281&&-3&-5&&7,I would require that A1 cell contains 1281,B1 cell contains &&-,C1 cell contains 3,D1 cell contains &-,E1 cell contains 5,F1 cell contains && and G1 cell contains 7.
Pls help in the same .
Thanks.,
Here i have tried to write code to separate numbers from non-numbers. Numbers and non-numbers are copied to different columns, like Excel Text-To-Columns. Code is a little crazy, if u need i will provide comments. As input the ActiveSheet.UsedRange.Columns(1).Cells is used.

For Each cellRange In targetRange
columnIndex = cellRange.Column

cellValue = cellRange.Value
If (VBA.Strings.Len(cellValue) <= 1) Then GoTo nextCell
For charIndex = 2 To Len(cellValue)
oneChar = VBA.Strings.Mid(cellValue, charIndex - 1, 1)
nextChar = VBA.Strings.Mid(cellValue, charIndex, 1)
If VBA.IsNumeric(oneChar) And VBA.IsNumeric(nextChar) Then GoTo nextCharLabel
If Not VBA.IsNumeric(oneChar) And Not VBA.IsNumeric(nextChar) Then GoTo nextCharLabel
cellRange.Offset(0, columnIndex).Value = VBA.Strings.Mid(cellValue, start, charIndex - start)
columnIndex = columnIndex + 1
copiedCharsCount = copiedCharsCount + (charIndex - start)
start = charIndex

Here is one more code. As a side product, function TextSplitToNumbersAndOther can be used independently as a formula to achieve the same effect.
To prevent accidental firing of the macro in a wrong sheet or a wrong column and overwriting neighbouring columns with scrap, named range "Start_point" should be defined by a user. Below this range in the same column, all data will be processed till the first blank row.

You can write a UDF (user defined function) to achieve the objective.
Your two example are in an order (ascending) to filter out into adjacent columns in Excel (A, B, C, D...)
So is it correct to assume logically, that you will never have scenarios where you will have to break the string into non-adjacent columns? e.g. 1234 goes to A, && goes to C, 3 goes to D... resulting in A, C, D.
Asumption 2: That your splitted-string is not going to need columns more than Excel can provide.
Steps you may try:
1. Check your string is not empty
2. Split it by the characters other than numerics
3. At the start and end of each non-numeric character you may proceed to the next adjacent column.
