Sort A Datagridview And Remove A Row From Its Sorted Position?

Jan 13, 2010

What I am trying to do is sort a datagridview and remove a row from its sorted position to the 1st row.

The problem I am experiencing is as follows:

in the source below, when the code runs "MeanRow" is populated with what is required. As soon as Rows.Remove() executes, the MeanRow datarow is lost. Why would this be if I'm declaring a new variable and simply setting it?

Code:
MeanRow = r
TabGrid(dgv.Name).Datatable.Rows.Remove(r)
Code:
Private Sub dgv_Sorted(ByVal sender As Object, ByVal e As EventArgs)
Dim MeanRow As DataRow

Move Position Of Specified Word Within String

Dec 9, 2009

I have a string

Example: Dim strList as String = "one;two;four;three;five;six;"

I want a function which will take in two values. a word, and a direction

Example: "three;" , "left"

I need to move move the given word "three;" further to the left until it finds the next occurance of ';'

Example: place the value "three;" just before the value "four;"

Result: "one;two;three;four;five;six;"

I will also need to move it to the right, assuming a direction of "right" is sent into my function. But I can figure that part out once I get the other concept working.

Finding The Position Of Certain Delimiter Using String.IndexOf?

Jul 28, 2009

What would be the simplest way to find the n-th position of delimiter in a string.For example, say, I have a string variable called FullFilePath that contains the path of a file, like, C:SourceFiles<mthyr><subject><filename>.txt From this, I would like to extract out mthyr, subject, and filename, using the delimiter, "".

I was hoping string.IndexOf would let me find the n-th position of the delimiter "", in which case I can use the result to do a string.Substring. But it looks like IndexOf only finds the first occurence of a certain string, which means I would have to interate this somehow to look for the n-th occurence.

Or is there another method that will help me do this more efficiently.

Replace Comma In String But Only At Specific Position

Dec 12, 2011

I am reading a csv file in VB.net and saving the line to a SQL database. At a later point in my code, the SQL line is retrieved in the application, and the Split function is used to get 'field' values. The Split is done taking comma as the separator. The application processes many other files (including excel), and the split function is used for all of them. The problem I am now facing is that one of the csv files I read, has a field value that starts with " followed by multiple values separated by a comma and ends with another ". The normal reading of the csv file results in each of those single field values is taken to be a separate value.

An example line is:
Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
Where there should only be separated to 4 columns, they get separated to 9 columns instead. What I want to do is replaced the commas after 'Bus' and until 'Toll' with a '?' instead. I have tried using Replace, including the overloaded one with starting position, but it ends up replacing ALL the commas in the line with '?'

Attempt 1:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine(intStartPos), ",", "?")
end if
Where vstrLine is Elker,MissB,"Bus, Taxi, Train, Ferry, Parking, Toll",800253
and intStartPos is the first instance of a comma after the "
It returns only the '?' and not the string with 1 comma replaced by '?'

Attempt 2:
If vstrLine(intStartPos) = "," Then
strRetVal = Replace(vstrLine, ",", "?", intStartPos)
end if
It returns a string with all commas replaced with '?'

VS 2008 Inserting A String Of Text At A Certain Position?

Sep 8, 2009

far it works! But it work's too well. What I'm trying to do is insert a string of text at a certain index position of a text file, underneath a certain line of text. So far I have:

'Controls Var 16
If CheckBox1.Checked = True Then
If Mytempstring.Contains("zrandomtextz=0") = True Then
Mytempstring = Mytempstring.Replace("zrandomtextz=0", "zrandomtextz=1")
ElseIf Mytempstring.Contains("zrandomtextz=") = False Then

[Code]...

It's inserting the text, but it's inserting it at every line of text in the file. So instead of one instance of "zrandomtextz" underneath "xinserttextx" I get "zrandomtextz" before every single line in the file. Can someone please help me as this has been an issue for months now? Edit: There are quite a few lines above this one, as in 50-150, so I removed all of the above section, however I can assure you that whenever it is simply replacing then writing to file it works flawlessly, it's only now that I'm having problems and this is when I try to insert new stuff under stuff.

Regex - Replace Space In A String At Random Position In .net?

Mar 1, 2012

I want to select a random space in a string and replace it with a word (%word%) but there is a problem. The position cannot be fixed as i want it to be inserted at a random break. Few things which iam considering :

1)break the string at a space and merge it with the word

2) find a random space and replace it with the word. I like this point and so far all i have is break the selectedtext into string array and then iterate over each line. But i don't know how to find a random string position? Any short and sweet code please?

If (rtfArticle.SelectedText.Length > 0) Then
Dim strArray As String() = rtfArticle.SelectedText.Split(New Char() {ChrW(10)})
For Each str3 As String In strArray

Search For New Line Position In A String Variable Using InStr

Aug 7, 2009

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:

"This is the update: I have an issue with the application"

I need only part of the data, that comes after the new line i.e. "I have an issue with the application".

For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.

I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.

How can I get the data I need?

Xml - Find The String Position (index) From A XPath Statement?

May 7, 2009

I'm looking for the actual index position in a given source string.I have the following string

"<a>
<b>zyx</b>
<b>wvu</b>

[code]....

I'm loading that string into a .NET XmlDocument object. Carriage Returns and Line Fees may be a factor here.

Dim xmlSearchText As New XmlDocument()
xmlSearchText.LoadXml(SearchTextBox.Text)
Dim selectedNode As XmlNode = xmlSearchText.SelectSingleNode(txtSearch.Text)

The following XPath Statement could be used to find the 3rd node:

a/b[.='tsr']

However, I need it to return a string index of 23 rather than the ordinal position of 3.

Saving Window Size And Position Multiple Monitors Toolbar Position Etc.

Aug 24, 2009

I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:

1. Multiple monitors. (and resolution between those monitors)

2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)

3. Sometimes the programs dont open on the right monitor they were closed on.

Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?
