Replacing Nodes In A Xml File?
Sep 5, 2011
I decided to use XML to handle some of my configuration chores. My XML file looks something like this:
<catagories>
<catagory path= "C: empwyoming" name="Wyoming">
<URL Filename="Picture1.jpg">http://www.domain1.com/pic.jpg</URL>
<URL Filename="Picture2.jpg">http://www.domain2.com/pic.jpg</URL>
[code]....
I'm wanting to manage this list in my program. Currently, I have written code to read the catagories into a combo box, and once a catagory is chosen, I can read the children URL nodes into a listview. I want to allow editing and re-arranging of the URLs in the listview, and I'll have no problems with that. So my question is, what is the best way to dump the listview back to the xml file? You should consider the contents of the listview as a replacement for ALL of the existing children in the XML file.

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

friend of mine has no HTML knowledge so I'm attempting to write a program that replaces certain parts of a html file to suit his needs.I've edited the HTML file and marked certain parts with "tags" like this:
#IMAGEURL1# I have a textbox where he can copy + paste an image URL and hopefully the #IMAGEURL1# is replaced with the contents of the textbox.
So can someone please enlighten me to-as how to open a HTML file (there's no textbox to display the contents just yet, I'll add one if needed), find the specified text and then replace it with whats in a textbox.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

I am loading a dataset with a csv file.I remove the quotes around each field in the csv file and I am splitting each field wherever there is a comma:Dim fields() As String = lines(i).Split(","c) The problem is that some of the fields have a comma in the csv file (surrounded by double quotes).How do I replace those commas with a space to avoid problems when loading the dataset?

So i have an .ini file where one of the lines is for the output of a file. i need to substitute the current output in the file with a filepath that is stored in my vb app (named filepath). so i need a snippet that will open the ini file, find the correct line, and place my variable in there. ill paste in what the ini file looks like
[PDF Printer]
output=C:\Users\bobbyt\Desktop\test.pdf
confirmoverwrite=no
[Code]....
its not code so i suppose i shouldn't place tags around it. so that first line needs to have my new filepath in it.

I have about 7,000 files (with temporary file names) that I need to replace with specific file names.
I figure I can match up the temp file names with the needed file names in
access. I'm not sure where to go from there.
I do not have to use a database if there is another way of going about it
but I do not think there is.
amounts of file names to unqiue IDs/names?

What I basically have is a small game which I want to count wins/loss/ties. I have no problem with the game aspect but need to know how I can replace a string in a csv file. IE: If Jim wins the game, his 5 needs to be turned to a 6. After googling quite a while I came across the replace() function, but it doesn't actually rewrite it back to the text file
Contents of users.txt:
Jim,1.jpg,5,1,0
Will,2.jpg,6,7,0
Tom,3.jpg,5,5,0

The issue I have, is if I try to use any sort of IO function after this (WriteAllLines, streamwriter, etc) - I get a process is being used and can't touch the file (because its being read).Must I somehow create a new file with a copy of everything including the replaced string?

I am using the following code, but cannot get this to work. I have got it to work if the replacement is just of one word. So if the word test is replaced by mouse and the only thing in the file is the word test, it works.
How can I replace like this:
CH_IPVOD_filename.mpg > replace the CH_IPVOD_ with nothing for the result of:
filename.mpg
?
I would like to replace every instance of ch_ipvod_ with nothing.

I've got two programs, one is the main and the other is the updater. So far iv'e got it so that the main program checks for an update by comparing its version number with the latest one that's stored as a text file on the server. If there's a newer one, the update program is started and the main one closed. The update program will then use a web browser component to navigate to the download link and download the new version. The only problem I'm having at the moment is, How can I get the new downloaded version to replace the current one in Program Files? and will this cause permission problems?

I created a setup project along with my main program everything compiles ok and I'm able to install a successfully. The problem I am experiencing is when I try to install over the previous version. I have set the setup property RemovePreviousVersion to TRUE , DetectNewerInstalledVersion to TRUE and I also increment the Version number and choose Yes when prompted to automatically change the ProductCode.
What I find is that when I install my program, the date on a subfolder changes, I don't expect the dates of the support files to change. but I do expect the date of my main .exe file to change. Unfortunately it stays the same. Running the program also shows that this file was not updated. I have read the MSDN articles on this but cannot figure it out.

I'm trying to do some simple XML manipulation by searching one XML file for a set of nodes and inserting them into another XML file at a specific location.I'm able to succesfully create a node list from one of the files using the following xpath statement [code].....
I'm struggling to see how I can easily select any node I want within the first XML file but the second file refuses to play ball! I've attached the second XML file should anyone wish to check that I've interpreted the structure correctly.

I have a binary file. If I look at it with a hex editor, the first values are:208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, ... etc.It has a length of 330240 bytes I have tried to open it and read it into a string so I can manipulate it and write it back. No matter what I use, I either don't get the correct number of bytes or the values in the string are incorrect. The most common error results in the first values being: 63, 63, 17, 63, 63, 26, 0, 0, 0 .... etc.It is interesting that it appears that any value > 63 becomes 63.
I get the 2nd values by a simple loop:
For lnx = 0 To 99
Debug.Write(Asc(line.Substring(lnx, 1)))
Next
I have tried a whole number of ways to read in the file, including filestream, My.Computer.FileSystem.ReadAllText, File.io.readAllLines, etc.All either give me a string length of about 324000 (not sure why) or, if they do, don't have the correct values. Yes, I have tried various encoding options.
I need to find a string (sort of like: "D" & Chr(0) + "L" & Chr(0) + "S" & Chr(0)... ) so I can then replace that portion of the string with a new value, then write out the file.I use the ".indexOf" to find the data in the string.Why can't I load the file into a string? Or, do you know of an easy way to find some text (similar to above) in a file and then replace the next x number of bytes with a new value and close the file?

I now have a similar xml problem. Now that I can create and add to the file, I only have two more problems to solve.
1) How do I remove all nodes (without starting over from scratch, hopefully)?
2) How can I limit the number of nodes in the xml file?
That should do it (for now at least) until somebody wants some other feature.[URL]..

Alright, I decided instead of Serialization or Access, I'm going be using XML files.
Now, I have them properly adding and editing, but I see theirs a property .SelectNodes( )
How do I use this ? I did a quick Google Search, couldn't find much. Here's the current Code I'm using to Edit my Document.[code]...
