View 1 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. The script is also extremely slow and seems to use quite a bit of memory. The arguments are ad
View 1 RepliesI want my Richtext box to be populated with a text string that contains HTML-style tags to set colour, underline etc.When I try to remove the tags using .cut(), the first cut always works, the second cut only sometimes.Here's a sample to test it:Create a new project and add a button and a richtext box.Add the following code:
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

This code works fine.The text between the tags is turned red, then the tags are removed.Now rem out the msgbox line and run again.Sometimes it works, sometimes the second cut fails with no message or warning.I am using Visual Basic 2010

View 4 RepliesI'm building a program in which it asks for your name and age and determines a ticket price based upon these details. I want it to show the person's name, then their age, (jump down a line) then their ticket price, and then it jumps down a line to show the next person's name, age and ticket price. Issue is, when it's meant to jump down to show the next person, it just completely deletes the last person's details.I'm using this line of code:
TxtFareShow.Text = (Name & Age & vbCrLf & Price) & vbCrLf
How do I fix this?
I'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

View 6 RepliesI've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
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'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 4 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.

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.
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.
