I'm reading in an xml file, which is working fine with no problems, but I want to re-format one of the elements data attributes slightly.
The XML attribute output is currently Wind: NW at 6 mph
What I want to do is extract just the number from the string, I figured an easy way would be to simply play with the length of the string and assign it to another variable.
However, I've ran into a little problem.
I can use windRtrim = wind.Substring(0, wind.Length - 4) (Where windRtrim is the amended string variable and wind is the string from above)
This returns Wind: NW at 6
Which is great, but the problem now is trimming the correct number of characters from the beginning of the string as it'll be different if the number were to go over 9 (ie. 10 and above)
I have an array filled with values from Excel cells. Each of the values is a concatenation of two things separated by a pipe, like "Machines|MachinesCode"
I need to, as I fill this array, strip out the pipe and everything in front of it so that the array being filled is only filled with the "MachinesCode" part of the cell value, but I haven't had much luck finding how I should do this. Each cell is dynamically filled and will never have a set length, so I can't set a trip by a particular number value of characters in the strings.
This subroutine is what I'm using. I am filling array FieldArray with another array (ExcelArray) currently holding the concatenated values.
Public Shared Sub PopulateFieldArray(ByRef FieldArray() As String, ByVal iFieldCount As Integer, ByVal ExcelArray(,) As Object)
Dim iIndex As Integer
For iIndex = 1 To iFieldCount
FieldArray(iIndex) = CStr(ExcelArray(2, iIndex))
Next
End Sub
But I don't know what to wrap around the CStr Excel array to cut off the pipe and all values before it while I fill FieldArray.

program makes strings from webbrowser documenttext.For example
String1 = "<span class""long-title"" title"" Informations here"
Im trying to remove all text before "Informations here" this is what i currently have.
dim mychar as char () = {"<"c, "s"c, "p"c, "a"c, '....thatandlike20moretill.... "e"c, """"c}
string1 = string1.TrimStart(mychar)
(Note that each letter or symbol inbetween the quotations is a part of the string (span = "s" "p"...)Now this works. Not all the time though and its a pain in the .. having to do "letter"c, all the time.. (I got over 10 strings lol) Im wondering if theres a way easier method to remove part of string from the beginning, maybe like still a certen part of the length..
I have a byte array with contents from a file in it, but I want to trim / remove the first element from it [byte(0)]. I've searched for days and experimented with a hundred different methods but they don't work.
[Code]...
Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
I have some questions about arrays.
1) Lets say I open a file in a byte array and I need to add 5 bytes of data at the beginning. How would I go in doing that? ex: attaching to arrays together.
2) How would I go in adding 1 byte of data in a bye array?
All i need to do is open part of a file in bytes. Add a letter and 2 numbers to it at the begging and a number at the end.All i need to know is how to attach 2 byte arrays together and how can u add a byte of data to an array.
my problem is how can i convert the 63 in the beginning of the number ex."639063100343" and change it to 0 ex."09063100343"

View 4 RepliesI've made a little map-maker for my tile game, which just stores a single digit for each tile. The problem I've noticed, is that when I save a digit, it tags a space on the end of it, so that when I read the file I have to read every 2nd character.... plus ofc it makes the file twice as large. Is there a way to trim the space from my digit when I save it to a text file?

View 1 RepliesI have a form which has a tabgroup with three tabs. One of the tabs has a bunch of utilities a domain admin would use. Is there any way to create a login form that grabs info from active directory, and based on the group you're in, the correct tabs will appear on the form. For example if you are in the domain admins group, that tab will appear, if you are in the helpdesk group it won't show.
View 12 RepliesI've got an unusual request. I have an image that will always have bounds that are of Base 2 (2, 4, 8, 16, 32, 64,...) in both dimensions. I need to know if there's a way that I can get a small 16 x 16 square (or smaller, still of base 2) portion of the image. I'm planning on overlaying a grid on this image that way the user can select a portion of it and then the program creates a dynamic image from the selected grid square to use. Is this possible to do? I did a quick search on the Image class and didn't see anything that stood out. Note: This is for framework 2.0, but not picky about jumping to 4.0 if necessary.
View 8 RepliesI have a large tab delimited text file to process each day (usually around 25 mb) consisting of usually well over 100,000 lines. The file is actually made up of about 9 or 10 reports separated by "END OF REPORT". I'm wanting to write each individual report to it's own text file. Some values may have trailing spaces or even contain nothing but spaces, so I am wanting to trim those to only the data, or be left with null. Ultimately each report will be imported into sql server tables. The code I have below runs successfully to completionwithout error although each text file is empty.

I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one

View 1 RepliesI have an VB.NET app that writes the status to a log file in text format. Over time, the file is getting large and I wanted to know if there is an efficient way to truncate the beginning of the file.
To make things easier, I am looking to specify a file size (say 2-3 mb) and I am writing the log using a StreamWriter:
Using strm As New IO.StreamWriter(filelocation.log, True)
strm.WriteLine("msg to write")
strm.Close()
End Using
I thought about using the strm.BaseStream.Length to determine how much of the file to cut off, but by using the .SetLength it would cut from the end - not the desired result.
All appears well, except for the zip codes that begin with a zero. I'm using a case statement to verify the zone, but VS2010, helpful as it is, removes the the lead zeros, after which said zip codes won't verify.strZip is put in through a text box, and a debug.writeline will tell me that VS stores it correctly, with the leading zeros. But when I get to the Case statement, it just will not let me look for a zero initiated number. I felt I was doing well by going with a string rather than something more numerical, but that apparently isn't enough.
