Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)

I was wondering what the easiest way is to get a portion of text from a string for example, you have:
"example1,example2,example3"
And i need to be able to get all three of the items separate:
"example1"
"example2"
"example3"
The length and number of items will change, I'm using a listview subitem
Lets say I have a variable: varEmail. It contains a variable equal to the user's email address, so it might contain a value likeNow, lets say I want to get just a portion of the email address, e.g. strip off the domain, like so:

I have a combobox which is filled with items from a table like this: [Code] What Im trying to do is to when I choose one name from the dropdown list the firstname shall go to one textbox1 and lastname go to textbox2.

But how can I get just a portion of the selected string in the combobox to a string so I can do a search on it.

1) I recall seeing a really cool option in VB.NET using LINQ to match using "LIKE%'
2) I know regular expressions will work and I suspect that will result in the shortest code and probably won't be too hard to read for such a simple test.
Here's what I did.
Private Shared Function FileNameIsOk(ByVal fileName As String) As Boolean
For Position As Integer = 0 To fileName.Length - 1
Dim Character As String = fileName.Substring(Position, 1).ToUpper
Dim AsciiCharacter As Integer = Asc(Character)
Select Case True

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

View 1 RepliesI am getting a filename in a String and need to get the name from this. An example:
Dim file As String = "Hello.png"
'I need to get "Hello". One way of doing it is:
Dim name As String = file.Split(ChrW(46)).First()
The problem with this method is; What happens if the filename contains a .?
[Code]....
I am trying to make a filename something like this:
dim Test as string = "name_" + now.toshortdatestring() + ".pdf"
The datestring is like MM/DD/YYYY, which is a particularly bad filename (who want slashes in their file names??)Is there a way to format the date string differently (ie MM-DD-YYYY)?What I was trying to do is tag the file with a date so I could tell when the last time that file was generated, and also keep multiple copies around for archive purposes. Maybe there is a better way and then I dont even need this differently formatted string?
Well lets say i Build a Program its called test.exe
Now if i Rename the Program to test2.exe how can i check with the Programm how my Program ist called now? Cause My.Application.Info.AssemblyName tells me only the AssemblyName not how the File is called at the moment.
How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.
If openFileDialog1.ShowDialog() = DialogResult.OK Then

I have a piece of code to debug. Because of unknown bugs it creates a dummy filename. I want to track all the pieces of code who fires that creates the dummy filename, so I can change the dummy file creation to a thrown exception. Since I the dummy filename is stored on a string, I plan to modify that string to contain an invalid NTFS filename, maybe containing invalid chars. Is there a reason to prefer some invalid chars over others? There are some predefined invalid NTFS filename destined to this purpose? (I may think of AUX , COM1 , LPT1 or PRN , but those names run the risk of start sending data to a port instead of throwing an exception).

I have a quite simple application that is having some random locks up. It's just a few text fields that the user fill it up, 3 sets of Radio buttons, one of them with flags to chose the language and click the PDF button. The application uses iTextsharp to load a PDf template, insert the text into it, depending on the language loads some extra text from a .xml file, and depending on the radio button removes the images from the PDF, closes the pdfstamper and uses [Code] to open the file with whatever PDF application the user have installed and closes itself.
Sounds simple, but after the application is installed in the machine (never in debugging mode) it randomly locks up the application. I tried re-publish the application commenting out the Start(filename) line and the thing stopped locking. And I double checked it, re-publish with the line again and it locked after just a few attempts. [Code]

View 1 RepliesI have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName
instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.

How can I only add the decimal part of a number to another one?
example: if a number is A = 10.25
Then X = 30
Y = X + 0.25 (Here it added 0.25 which the decimal only NOT 10.25)
Another example, If X = 16.35, A = 102.001
Y = 16.351
