Array Of Strings Contains Carriage Returns That Can't Be Found
May 9, 2012
I have used StreamReader to read the contents of a file to its end, and parsed each line into an array entry for an array of strings. That part works, and I have verified that each array entry does contain the proper line entry from the file. However, if I were to go and print out (say, in a MsgBox) each line, every line after the first one would look like (Carriage Return)(proper thing), yet searching for the CRs using InStr yields that there is no CR or ControlChars.NewLine etc. character in the string. I'll show you my code:
Dim FileParse(255) as string
Public Function FileRead(ByVal FILENAME As String)
Dim sr As New System.IO.StreamReader(System.AppDomain.CurrentDomain.BaseDirectory & FILENAME)
Dim FileData As String = sr.ReadToEnd
[code]....
I just set the For Loop from 0 to 10 because I am unsure how to tell the loop to end when it has finished with the last entry of the Lines() array, and since the program will later be writing to the source file, it is likely that the number of lines will change (which is why I just arbitrarily set the FileParse array to have 256 spots).
I'm working on a program that stores some of its configuration information in an XML file. I'm able to read and write the xml files ok and everything works, but I would like to be able to open the xml files in other programs such as programmer's notepad. When I open the xml file in programmer's notepad, all the text is on a single line. Is there a way to embed carriage returns into the xml file?
I am using Visual Studio 2005 and .NET 2.0 to display data pulled from a Oracle table. I am trying to display a notes column, but the column is not displaying the CRLF characters properly. The text is showing as a single line.
Private Sub BindNotesGrid() Dim colRequestNotes As New BoundColumn() Dim colCreatedBy As New BoundColumn() Dim colCreatedDate As New BoundColumn()
Is there any way, in my project's properties, to put a carriage return or a line feed in the Description field of the Assembly Information dialog box, in which the Description information would then appear in the description field of the about box of my project?
Where Me.Note is a string that I am looking for and replacing it with the contents of txtNote.text. And then storing it all back in the string CoverPage.CoverPage is an rtf string that will holds place holders for the text I want to change.(That works) But when i update the note that may have a carriage return in it, the coverpage does not reconize the carriage returns comping from the Multiline textbox when its displayed.I have tried replaceing Enivronment.Newline with vbCr, vbCrl and whatever else I can think of. is there an issue with taking a string carriage control and tranfering it to a rtf carriage control?
I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :
Protected Sub MakeWordListBeforeTab() Dim filename As String = "D:lao�0001.txt" 'read from file'
[Code].....
I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.
I had a strange error in a VB6 app this morning and it all stems from the fact that IsNumeric is not working as I expected. To me this seems like a bug.
This code displays 4.15877E+62 in a message box:
Dim strMessage As String strMessage = "0415877D57" If IsNumeric(strMessage) Then
[Code]....
I am guessing that the runtime engine is incorrectly thinking that the D is in fact an E? I think this is a bug though as the exact same code in VB.NET outputs not numeric Is this a known issue with IsNumeric?
I'm trying to sort an array based on a structure but whenever I do this, it basically erases all the data in the entire array.I have verified that the array is populated correctly, it is when using array.sort that everything returns blank.
I currently have a VB.NET dll that returns a jagged array of double. This is the declaration:
Public Function CalcMatching(ByRef dataArray1 As Object, ByRef dataLen1 As Integer, ByRef dataArray2 As Object, ByRef dataLen2 As Integer, ByRef matchingType As String) As Double()()
It works well inside VB.NET, but when I insert it into a VBA project, I noticed that after the execution of the funtion, while retrieving the data, the "Type mismatch' excpetion is raised inside VBA.I searched over the internet, but I could not find a delcaration of a jagged array inside VBA. is that possible? If yes, how can I do it?
i am trying to write a function which should return a 2D array , please advise what is wrong with.
vb.net Public Function Cursor(ByVal SQL As String, Optional ByVal PARA1 As String = "", _ Optional ByVal PARA2 As String = "") As String(,) Dim Cols, roWES, I, J As Integer
I am trying to search an array and then say whether the result was found or not.
So far i have:
Option Explicit On Module Module1 Const MaxAnimals = 20
[Code]....
Now i have looked online and all of them seem to give you like ready made things on VB but i have not used them yet and i know there is an easy way of doing it as my friend managed to do it before but i can't get hold of him.
Basically it is a program (There is more of it but this is not necessary for this) which puts the names of animals into an array then you can either add another animal, or in the sub i am doing at the moment view all the animals in the array but i can't work out how!
Correct the problems with this function, and then extend it so that it also returns a usable array of pointers to some structures.
The extended version of this function should: Maintain the same "char *" return type which returns a pointer to a usable, for storing a C string, memory buffer.
In addition, also return a usable array of pointers to structures. This array of pointers is of variable and random length, which must be obtained using GetNumberOfSomeSeqsToGenerate(), which is called, ONLY, from within this new extended version of the function.
The type of these structures and the function that should be used to get these structures are defined as follows:
typedef struct { char* name; /* '\0'-terminated C string */ int number; } SomeSeq;
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?
I would like to get fill a String array with all the images found within a directory.Till now i use the following to get all the images with jpg format Dim List() as string = Directory.GetFiles(Path, "*.jpg")Now i would like to extend it and get all the image formats.Could i use the directory.GetFiles combined with an "ImageFormat enumeration"?
I have following code somewhere in my VB.NET 2008 program to create an array of files found in a folder: Dim objFolder As New IO.DirectoryInfo(strXMLImportPath) Dim arrXMLFiles2Import As IO.FileInfo() = objFolder.GetFiles("*.xml") ... UpdateFileQ(arrXMLFiles2Import) [Code] .....
When setting "option strict" to on, I'm getting following error on the line: lbFileQ.Items.AddRange(dirlist) Overload resolution failed because no accessible 'AddRange' can be called with these arguments: 'Public Sub AddRange(items() As Object)': Option Strict On disallows implicit conversions from 'System.Array' to '1-dimensional array of Object'. 'Public Sub AddRange(value As System.Windows.Forms.ListBox.ObjectCollection)': Value of type 'System.Array' cannot be converted to 'System.Windows.Forms.ListBox.ObjectCollection'.
Although everything works fine with option strict set to off, I'd like to correct this problem. Also note that array "arrXMLFiles2Import" is used later on in the program, so I can't change anything on that.
I'm attempting to run my first program in vb.net and everything works BUT the array.
Here is the archive: [URL]
The problem occurs in the Maps.vb file on line 17 when the assignment of variables to the array starts. When running the breakpoint debugger you will notice that when it reaches line 17 it just skips the whole sub and then the next breakpoint is unable to be found.
