here somenode has some children where first and last children node names are same where as other nodes except the first and last node has some diffrent name ( identical to each other ). I am creating a function to insert a node at specific position, I am not sure about the criteria but may be in the mid.
how can I insert node in specific position. I am using XMLnode.appendChild method for insertion Do I need to rearrange/sort nodes after insertion. How can I determine what is structure and how should I find where the new node should be added according to current document structure.
I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position() MyPosition.X = 400 MyPosition.Y = 400 Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
I am using a form with 2 buttons and one treeview in the first button , I can add a node with this code [code]in the second button i can add a node but only in the last node c.nodes.add("World")My question is how to add a node in the third node or a specific node of the treeView
I am trying to work out how I can insert the string "End" into my textbox at a specific cursor point? (where the '???' is in the code below)As you can see by the code below this will happen when the user clicks return on the keyboard within the textbox.
I have the code to get the cursor index which is being stored as integer 'intcurrentcolumn'. Private Sub Enter_Click(ByVal Sender As System.Object, ByVal k As System.Windows.Forms.KeyEventArgs)
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.
I have two XmlDocuments that both have a namespace attribute specified. Both documents have the same structure, but contain different data. I can't seem to get a specific node tree from one document added to the end of the same node tree in a second document. Here is an example of my two documents:
I certainly know this is wrong... I've tried serveral different approaches. This particular approach adds all <Item> nodes to the destination document, but it adds them to the very bottom of the document instead of after the last <Item>. how to add a specific node tree an XmlDocument to a specific position in another document? Again, there is a namespace involved and the <Item> nodes have nested nodes/elements under each one.
NOTE: The <Id> nodes have example data to show uniqueness only. I can never count on any kind of numbering. The order of each <Item> node is totally unimportant. I'm just assuming it will be easiest to add additional <Item> nodes after the last one in the destination document.
I bring this file into a dataset in visual Studio. The problem ixs that I cannot associate a particular set of options with a particular line item - I can't distinguish Item num="0" from Item num="1" and so forth, because the element 'Item' presents itself as a table withing the dataset, and the element 'Option' also presents itself as a table within the dataset. I don't know how to connect the two.
I've A treeview with parent nodes and all parents have also childrens. i need to sort only the childrens in one of the parent nodes without sorting the parent nodes in the treeview because i want to keep the order of the parents.how can i do this?
That gets me the first vehicle in the XML, so then I will know the ID of the driver of that vehicle based on the GoverningDriverIdInfo/ItemId. Then I need to match that ID with the id property of the driver node. Then get the value of the DriverInputSetGoodStudent node.
<session> <data> <policy> <line>

I see that the code didn't paste in the quite correctly, there is an "end session" tag that isn't appearing in the code block.
The process I currently use to insert a string into a text file is to read the file and modify it as I write the file out again which seems to be how everyone is doing it.
Since .net has such a diverse library I was wondering if there was a specific command for inserting a string at a specific line in a txt file.
I would imagine it would look something like this:
dim file as file file.open("filePath") file.insert(string, location) 'this isn't actually an option, I tried
I am making a game and decided to add a high score section. I currently have this code setup to insert and read from the database, I set the insert code to a bottom just for testing purposes.[code]There are three columns in the database rank, score and name. I set the rank to auto number so the database would assign the player rank automatically, how would I go about inserting the score into the relevant place inside the database and moving the other scores to their new relevant places?

So I have a TreeView and it has about 7 parent nodes that have 3-5 children each. All of these children nodes when click navigate to a URL. What I would like to do is have one parent node auto-expand based on the URL and the other parent nodes to collapse.
I am to search for a particular string in a text file, which I can do using a regular expression.Upon getting this string I am supposed to search for another one then, find a value corresponding to some time step and write it to an excel file.How do I indicate the position from which I want my reader to commence? Let's say my match.Index returns 100 000 as the location for the first string I was searching for. How do I then resume my new search at this point?
I have tried with filestream but it also changed the strings that is in position
Dim fs As FileStream = File.Open("C: est.blah", FileMode.Open, FileAccess.ReadWrite) Dim testdata As String = "a" fs.Write(Enc.GetBytes(testdata), 0, testdata.Length)
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 '?'

How can I make my MDI child form to load in a specific position in the parent form? Or preferably, how can I make the child form Dock Inside a Panel in the parent form?
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.
i have a treeview which has a bunch of parent and child nodes preset at design time, there is 1 parent node tho which is called developer, that i want to add child nodes to at runtime.When the form first loads im trying to have it check a text file and for each line in the text file add the text/string from that as a child node tot he 'developer' parent node.
