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)

So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
String myTestValue = "NotModified";
TestMethod(myTestValue);
System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....
And what is going on under the hood? I would have bet my life that the value would have changed....
<script runat ="server" >
Dim objDT As New System.Data.DataTable
Dim objDR As System.Data.DataRow
[code]......
I know strings are immutable, so the minute you change a string reference's value .NET makes a brand new string on the heap. But what if you don't change the value of a string reference; rather, you simply pass it into a function ByVal -- does this operation copy the string value on the heap as well? My inclination is "no," but I'd like to confirm.
For example:
Public Function IsStringHello(ByVal test As String) As Boolean
Return (String.Compare(test, "Hello") = 0)
End Function
Calling program:
Dim myWord as String = "Blah"
Dim matchesHello as Boolean = IsStringHello(myWord)
I know passing myWord by value makes a copy of the reference to "Blah", but since I have not tried to change the string itself, would it make another copy of the string on the heap?

I'm making this program that opens the same forder in every pc but it identifies the pc name to do it.
Public Class cv7import Private Sub cv7import_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

but I want it to do it with the pc's name and I'm not sure how the environment.systemdirectory works, or even if it's the right one to use. Is it the right thing to use or is there a better solution.
I 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]....
Just as a secondary question, usually I reduce: -(ByVal sender As System.Object, ByVal e As System.EventArgs) to just () for most occurrences of auto-generated subroutines. Is there any harm in doing this? I cant see any reduction in performance but do get more readability.
View 8 RepliesI 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?
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
Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName
Properties.Settings.Default.Save();

View 2 RepliesI 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).
View 1 RepliesI 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]
I 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.

this code does not work...when I put it in a msg box to show the error : it appears as buton1.performclick()and if I write button1.performclick() manually ,then it does the operation.I want to trigger the perform click operation from a textbox.text. Main error is:Public member 'PerformClick' on type 'String' not found.
I'm having a bit of trouble figuring out this error and what it means. Here is the code that is throwing the error,
For Idx = 1 To cboCallType.Items.Count - 1

For I = 1 To cboCallType.Items.Count - 1 ' Set Index to look at the array
Public member 'Selected' on type 'String' not found. I'm assuming this error means you can't select a String in the combobox? I always thought you could, I'm just checking to see if one of the items were selected before moving on with the code, what other way is there to accomplish this and/or what does this error actually mean and how do I go about solving it?
