I need a regular expression that I can use in VBScript and .NET that will return only the numbers that are found in a string.
For Example any of the following "strings" should return only 1231231234
123 123 1234
(123) 123-1234
123-123-1234

I want to run a check on a String right before I append it to a StringBuilder to make sure only numeric characters are in the string. What's a simple way to do that?
View 7 RepliesI am new to VB (and coding in general) and I'm wanting to make a check digit generator. To do this I need to take the a user text input and split it into individual digits so that I can then calculate the check digit.

For some reason I can't figure this out. Here's my code. colorTextbox.Text =Format(Hex(ColorBox.Color.G), "00")What I want it to do is format the Green Hex number to be "00" instead of just "0" when the color is something like blackhis has proven to be very stressful and this Format command makes no sense to me anymore (worked differently in 2005).For one, whatever I put in the quotes ("00") is what comes out in the text box. Butaccording to the command parameters, "00" should be the format, not the actual text! So then I tried any string format I could think of (## etc.) along with switching the order and I STILL can't figure this out.
View 16 RepliesHow to extract digits from the beginning of a string?
1234A - should output: 1234
123AB - should output 123
12ABC - should output 12
1ABCD - should output 1
This is an example of the text I want to modify:
0110
0001
0001
1000
[Code]....
Here, I want to replace two-line digits in bold(0110 0001) with a different sequence as the program scans the text line by line. But two things complicate the task:
1. the comma lines should be ignored, but
2. they also should stay intact after changing the digits.
I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

I am struggling to extract a 'matched' string and wonder if I am missing something simple.Let's say my code finds a string 'abcdefgh -john. smith 1234567 a123-a-123-f the last search, abc, 123 ;'I am searching this string for the pattern '[a-z]###-[a-z]-###-*'I know this text appears in the string as 'a123-a-123-f'I would like to be able to return the matched string value 'a123-a-123-f' to a variable.If I place a wildcard * in front of the pattern, it will find the text, but obviously everything else in front of it, is there a way that somebody can think of to strip the variable without using the preceding wildcard?I am not worried about the wildcard on the end of the string as I can strip back to the last space.[code]

So this should return all filenames of that directory
like:

With that said, shall the Private Property Attributes() As String() not return the values of DirectoryAttribute placed over the interfaces properties as well, since I specify True in the inheritance parameter of the Type.GetCustomAttributes method?
I have an third part dll that have a function that returns a string.When I call the function I got for example "123456" back. At least it seams like that, but when i do mystring.length it does not return any length. If I set the text property of a label it shows "123456".
When I have the string I got from the dll I send it to a webservice function:
rem call dll and get string
dim mystring as string=mydll.getstring()
rem Send it to the webservice
webservice.SaveString(mystring)
The webservice crashes with an webexeption ("protocoll error") when I send in the string I got from the dll. If I instead send it like this:
rem call dll and get string
dim mystring as string=mydll.getstring()
rem Send it to the webservice
dim FixedString as string = mid(mystring,1,6)
webservice.SaveString(mystring)
Then it works and everything is fine. That leads me to think that the string I got from the DLL is in someway not terminated correct.And I dont know how to fix it from vb.net (I cant change the DLL)and I dont know in beforehand how long the string will be.The dll does only work on site when specific hardware is connected so I can't sit at the office trying to fix this in dev-environment. So I would like to have some possibly solutions to this before I go to the customer again.
Edit 1:I tried to just do a loop that looped from 1 to 100 (because I dont know the real length) and tried to copy all characters that <>"" to a new variable but it didnt work. I didnt try other variants because the day was over and I had to leave the customer site.
Edit 2:The DLL Im talking to is made in VB6. That DLL is talking to other DLLs that is made in C++ (I think).
My program < - > vb6-DLL <-> c++-DLL <-> hardware

View 3 RepliesI'm sure but can't see the answer. Currently going through a string "DO While Not ts_IN.AtEndOfStream" looking for information. This includes then checking another string (while inside the first) for matching reference point for further data.
So within the first loop, I have a second loop "Do While Not ts_IN2.AtEndOfStream". And looping through that string searching for the reference point.
This works initially, but after awhile don't find anything because it is not going back to the start of ts_IN2 string each time loops on the first section.

Is it possible to do this, I can't seem to find a method that works?
