I have placed the following in cell A1:
"a lot of text marker: xxx some more text"
I would like to copy the xxx value into cell A2.
Any suggestions on how this could be done?
Thanks
=MID(A1, FIND("marker:",A1) + LEN("marker:"), 4)
I am assuming that the xxx (per your example) is 3 characters long and a space is present between "marker:" and "xxx".
Just my two cents. Find() is case sensitive so if the text in A1 is
"a lot of text Marker: xxx some more text"
Then Find will give you an error.
You can use Search() in lieu of FIND()
=MID(A1, SEARCH("marker: ",A1) + LEN("marker: "), 3)
Also depending upon your regional settings you might have to use ";" instead of ","
If you wanted a VBA solution, this worked for me using your sample input:
Function GetValue(rng As Excel.Range) As String
Dim tempValue As String
Dim arrValues() As String
' get value from source range
tempValue = rng.value
' split by ":" character
arrValues = Split(tempValue, ":")
' split by spaces and take the second array element
' because there is a space between ":" and "xxx"
GetXXXValue = Trim$(Split(arrValues(1), " ")(1))
End Function
To use, put this code into the sheet module (see Where do I paste the code that I want to use in my workbook for placement assistance) and then put the following into cell A2:
=GetValue(A1)

Im trying to perform a search in DXL of a string that ends with specific characteres Im not able to find the way to perform this.
Example, I'm looking for
" A: 23.1.23.2.4"
But if this contains at the end the character "~" the find function does not work
Example Where the skip list contains "A: 12.2.1.4.5~ text text text text"
I just need to know in the object.text contains A: 12.2.1.4.5
string string_text = "A: 12.2.1.4.5"
if(find(skip[i],string_text,string_text)){
modify_attributes(req_text)
}else{
output << "stgring not found : "
}
use a regular expression, like this
void modify_attributes (string fulltext) {print "modifying.."}
string fulltext = "A: 12.2.1.4.5~ text text text text"
Regexp searchme = regexp2 "A: 12.2.1.4.5"
if(searchme (fulltext)){
modify_attributes(fulltext)
}else{
print "string not found "
}
The "find"-method for Skip lists is O(1), if I am not mistaken. But for that to work properly, the key, you are asking for, has to match exactly.
So, to benefit from the speed of value-retrieval by the find method, I suggest, that you have a look at your code part, where you put stuff into your Skip, (only put "clean" information in the Skip, which you know, you want to ask for later on).
That of course only works, if you have the possibility to do so, i.e. you don't get the Skip from somewhere you don't have control over..
I am parsing an RSS feed that
returns has the title in this format:
<title>Some Data with spaces / Bahnofstrasse 22</title>
so the first thing I did is to replace the spaces with a +
String result = _items[index].title.replaceAll(new RegExp(r"\s+\b|\b\s"), "+");
however, what I need to do is to select only the text after the / so in this case Bahnofstrasse 22, remove the spaces and add a city (e.g. Zurich) before the address so the desired results would be
Zürich,Bahnofstrasse,22
so essentially select all text after /, add Zurich and replace spaces with ,
If you know that the data will always be separated by a /, you could look at the second element of the split. For example,
final result = "Zürich," +
_items[index].title
.split("/")[1]
.replaceFirst("<", "")
.trim()
.replaceAll(" ", ",");
Regular expressions would only really be useful if, for example, the format of the data were variable.
I need to pull out (parse) the middle section of a data record, the typical record is similar to this string:
CARY 12345 (Supporting documentation here).
What I need to do is pull out just the 12345 portion of the data record. I've been using this CF code:
cnumber = '00' & listFirst( listLast( ctic, ' ' ), ' ' );
But the results output like this:
00(Supporting documentation here).
Instead, I would like the output to be:
0012345
If you're certain that your data would always look like that, and you always want to get the second item, you could do something like:
listGetAt(myData,2," ")
To pad with zeroes, you can use numberFormat():
numberFormat(listGetAt(myData,2," "),"0000000")
but this makes a number of assumptions about the format of your data and will break down if it doesn't match.
Try Mid and Replace together
<cfoutput>
<cfset str = Mid("CARY 12345","5", "6")>
<cfset str = "00"&str>
<cfset str = Replace(str, " ","","All")>
#str#
</cfoutput>
I need to take/cut first 300 words or characters from a string.
That means, I need a limited number of characters from a string, from the beginning.
Something like truncating.
Is there a function to do this?
str = "many words here words words words ..."
first_500_words = str.split(" ").first(500).join(" ")
first_500_chars = str[0..500]
Depending on the size of your text and performance needs, one option is #text.split(/\s+/).slice(0,300).join(' ')
If you actually want to truncate on character level, which is advisable because different words differ in display length quite a bit, use:
def truncate_words(text, length = 300, end_string = ' …')
words = text.split()
words[0..(length-1)].join(' ') + (words.length > length ? end_string : '')
end
which I found here: http://snippets.dzone.com/posts/show/804
If you're using Rails, you can also use string.truncate but it does not take into account word boundries.
str = "this is really long string which I want to truncate..."
str.truncate 300, separator: " "
or if you prefer to youse brackets
str.truncate(300, separator: " ")
It's the most elegant solution of all above. As you mentioned in the topic, you use Rails so it will work. If you code in raw Ruby, you should write something like this:
str.split.first(300).join " "
The split method no need to take argument if you need to split the text by spaces.
The max number of characters you can use in string in a vba function is 255.
I am trying to run this function
Var1= 1
Var2= 2
.
.
.
Var256 =256
RunMacros= "'Tims_pet_Robot """ & Var1 & """ , """ & Var2 & """ , """ ... """ & Var256 """ '"
Runat=TimeValue("15:00:00")
Application.OnTime EarliestTime:=Runat, Procedure:=RunMacros & RunMacros2 ', schedule:=True
It runs a procedure at a certain time and passes a bunch of variables to it. but the string is too long.
Update:
Regrettably I am sure it is not the watch window.
Also, it isn't really the max size of a string that I'm dealing with. It's the max size of
a string in a vba function.
For example this function works.
Sub test()
Dim RunAt As Date
Dim RunWhat As String
RunAt = Now + 0.00001
RunWhat = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" & _
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" & _
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" 'that makes 254 'a''s
Application.OnTime EarliestTime:=RunAt, Procedure:="'" & RunWhat & " 12'"
End Sub
Sub aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(m As Integer)
MsgBox ("it works!" & m)
End Sub
But if you change the 12 to 123 it breaks
Example
Sub test2()
Dim RunAt As Date
Dim RunWhat As String
RunAt = Now + 0.00001
RunWhat = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" & _
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" & _
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" 'that makes 254 'a''s
Application.OnTime EarliestTime:=RunAt, Procedure:="'" & RunWhat & " 123'"
End Sub
Sub aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(m As Integer)
MsgBox ("it works!" & m)
End Sub
This code does not work, I'm pretty sure it's because a vba function cannot handle a string with more than 255 chars.
Even if you're in Excel and call a function and give it a string longer that 255 chars it doesn't work.
Try in cell A1 =vlookup("really long string", A1:Z10, 1) and then put the really long string somewhere in that range. The vlookup will fail (not fail to find it, but you won't actually be able to do it)
Also I am aware that there is a max length to a sub name, I'm just under it. Sorry that it look so ugly.
Update 2: so I just ended up printing the variable to a sheet and getting the function called by ontime to read them off the sheet. :(
I may have missed something here, but why can't you just declare your string with the desired size? For example, in my VBA code I often use something like:
Dim AString As String * 1024
which provides for a 1k string. Obviously, you can use whatever declaration you like within the larger limits of Excel and available memory etc.
This may be a little inefficient in some cases, and you will probably wish to use Trim(AString) like constructs to obviate any superfluous trailing blanks. Still, it easily exceeds 256 chars.
This works and shows more than 255 characters in the message box.
Sub TestStrLength()
Dim s As String
Dim i As Integer
s = ""
For i = 1 To 500
s = s & "1234567890"
Next i
MsgBox s
End Sub
The message box truncates the string to 1023 characters, but the string itself can be very large.
I would also recommend that instead of using fixed variables names with numbers (e.g. Var1, Var2, Var3, ... Var255) that you use an array. This is much shorter declaration and easier to use - loops.
Here's an example:
Sub StrArray()
Dim var(256) As Integer
Dim i As Integer
Dim s As String
For i = 1 To 256
var(i) = i
Next i
s = "Tims_pet_Robot"
For i = 1 To 256
s = s & " """ & var(i) & """"
Next i
SecondSub (s)
End Sub
Sub SecondSub(s As String)
MsgBox "String length = " & Len(s)
End Sub
Updated this to show that a string can be longer than 255 characters and used in a subroutine/function as a parameter that way. This shows that the string length is 1443 characters. The actual limit in VBA is 2GB per string.
Perhaps there is instead a problem with the API that you are using and that has a limit to the string (such as a fixed length string). The issue is not with VBA itself.
Ok, I see the problem is specifically with the Application.OnTime method itself. It is behaving like Excel functions in that they only accept strings that are up to 255 characters in length. VBA procedures and functions though do not have this limit as I have shown. Perhaps then this limit is imposed for any built-in Excel object method.
Update:
changed ...longer than 256 characters... to ...longer than 255 characters...
Are you sure? This forum thread suggests it might be your watch window. Try outputting the string to a MsgBox, which can display a maximum of 1024 characters:
MsgBox RunMacros
This test shows that the string in VBA can be at least 10^8 characters long. But if you change it to 10^9 you will fail.
Sub TestForStringLengthVBA()
Dim text As String
text = Space(10 ^ 8) & "Hello world"
Debug.Print Len(text)
text = Right(text, 5)
Debug.Print text
End Sub
So do not be mislead by Intermediate window editor or MsgBox output.
Couldn't you just have another sub that acts as a caller using module level variable(s) for the arguments you want to pass. For example...
Option Explicit
Public strMsg As String
Sub Scheduler()
strMsg = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
Application.OnTime Now + TimeValue("00:00:01"), "'Caller'"
End Sub
Sub Caller()
Call aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa("It Works! " & strMsg)
End Sub
Sub aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(strMessage As String)
MsgBox strMessage
End Sub
Excel only shows 255 characters but in fact if more than 255 characters are saved, to see the complete string, consult it in the immediate window
Press Crl + G and type ?RunWhat in the immediate window and press Enter
One of the main causes of this problem that I’ve run into is the fact that the entire procedure-plus-arguments string is limited to 255 characters, including the procedure's containing Excel file specification (automatically added by Excel), which is aggravated by Excel’s brain-dead default specification of the file's full-path\name. So, if you have very deep folder structures (like I do) combined with long-ish, descriptive file names and descriptive folder names (like I often use), then that factor can be a frequent problem when using OnTime.
WORKAROUND: I always (!) explicitly include the containing workbook’s name, which apparently alleviates Excel from having to automatically do so (in its nonsensical manner):
Sub CallOnTime()
Application.OnTime Now + TimeSerial(0, 0, 1), _
"'" & ThisWorkbook.Name & "'!'TargetMacro 37,""Some really long String parameter…""'"
End Sub
Sub TargetMacro(I As Integer, S As String)
MsgBox "I=" & I & ", S=" & S
End Sub
That buys me a lot of string-length real estate to use for the called procedure's arguments.
IMPORTANT: note the inclusion and position of the single-quoted bang delimiter ('!') in the above example.
My guess is that the original designer chose to include the full file-path along with the procedure's containing file name to avoid identification ambiguity with other workbooks running under the same instance of the Excel application. But that's a nonsensical rationale because Excel doesn't allow multiple workbooks with the same name to be opened under a single instance, even if they exist under different folder paths (which, of course, they would have to).
Some additional space-saving tips:
If the parameters include a worksheet specification, use its numeric
sheet Index property instead of its name.
Eliminate any space characters around the comma delimiters.
