Searching One XML File For A Set Of Nodes And Inserting Them Into Another XML File?
Aug 21, 2011
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 need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.

I am currently stuck on searching an xml document to find a single node so that i can insert edit changes from a ui to the text of the node.
[Code]...
What i am doing is i have a drop down menu on a ui that a user selects a query and then the query text is displayed for editing. When the user clicks the save button it will take the edited query and replace the text of the original query. The only problem i am having is i can't find any example of how to do an xpath to find the selected query from the drop down menu.
Dim QueryText As XmlNode = QueryList.XMLDoc.SelectSingleNode("/Queries/Query/Text")
This gets the text of the first query but i need it adjusted to search the xml document for whatever query the user has selected... once i get the path able to find the selected query i should be able to finish this devil of a task.

I'm simply trying to merge 2 xml documents (adding nodes from one into the other). I've done some Google searching, and tried a few things, but I always get the same error "The node to be inserted is from a different document context" I'm sure I'm missing something simple, just seems like this should not be that difficult. Here's my code:

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 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]...

I am trying to parse this xml file, which has some nested nodes. I don't know how to put the xml file content that looks neat here. if you can tell me how, that would be great too.And this is my code. I am able to retrieve some info, but some of them is not correct (strGrant has values that is supposed to be for strSupport).
Dim strGrant, strSupport, strDatabank, strWeight, strNumOfGrants, strNumOfSupports, strNumOfDatabanks As String

I'm trying to make a script that searches for multiple .TXT files in a directory, and then searches the text of each file for a matching string(ie. "turtles"). It will search each file for the word "turtles". I've been on google trying to figure this out for a while, I'm guessing StreamReader is the way to go?

This is an veriation on a previos thread of mine (les complicated I think)
All .png Image Files in a Folder is named as 6 diget numbers.
Forinstance a "2" wil apear as "000002"
"22" as "000022"
"42" as 000042"
Can this files be searched by numeric value insted of a string?
So if I then searced fot the value of 2 I will get file named 000002 and not file named 000042 or 000022

I have been searching all over the forum and internet, but seems to have a hard time finding some help on how to search for a file at unknown location.
The reason is that, I made an easy form that helps some friends of mine find around a website more quickly.
Now this is what I want.
They have a game installed on the computer, and I want my program to search for this file and execute it afterwords.
F.eks
I have 4 HD's and WOW is on the 3rd. I want this software to search all the HD's to search for Wow.exe.

I have some code that does what I need it to do, But I am going to have make changes to accommodate the user request. Basically the program searches a folder for a paint code, ex. 351X035. When the code is found it displays a link so the user can click it to open up a PDF. The way I have it setup now is that they have to know the exact paint code for it to pull the link to the file. I need to search to find the file(s) with less than the exact code.

Im brand new to programming. Apart from doing a few digital dashboards in excel i have zero experience with vb or creating code. You may need to be patient.What i am trying to do is from my form, browse to a pic in a folder and insert it into a picture box in the program. the pic should insert itself into the program after it has been selected, and the picture should resize itself to fit the pic box (or viceversa if need be)
I have looked at some similar threads on this issue but none of the code in those solutions is working for me.

I've been using VB.NET for a few years now, but I never really got into binary files. How do you add onto binary files from the beginning? Here is some example code:
Dim writer As New IO.BinaryWriter(IO.File.Open("C:\Users\Dameon\Desktop\newbin.bin", IO.FileMode.CreateNew))
writer.Write("HELLO WORLD!")
[Code]....
How can I add onto the beginning of the file without overwriting what's already there? I'm trying to make my own file archive format. I have the compressing/decompressing down, but now I'm implementing adding/deleting a file after the archive already made.

I need some guidance on the best way to proceed with searching a file content.I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file.These files contain information that is produced from another application and therefore I am unable to change the format of the file.This file contains information that I want the user to be able to be able to enter search criteria in a form that then searches this file and returns information. The individual information is split into sections of data and this is defined by the section start label lbl{ and the end label }} Therefore the below information highlighted in bold is an individual section
lbl{-32768 21 12 0 text {Equip no: P-102BDescr 1: RECYCLE PUMP-BDescr 2:}}lbl{-32768 21 28 0 text {Equip no: D-100Descr 1: COLUMN RECIEVERDescr 2:}}Now comes the hard bit, in the bold section above you will notice that there is some text Equip no: P-102B I want the user to be able to enter in a form *102B* and for it to return -32768 21 12 0 which is after lbl{ and before text.Now obviously I could loop through the whole file to do this, however I am very concerned about RAM usage and also the time it will take to do this. Obviously the user could use this search option over and over again and therefore we would be searching the same file over and over again. One of my thoughts was to read the file once and output the content in an Access Database table and then use SQL to get the information? However would the user require Access on there machine to be able to do create the database or could I just ship a blank Access database with my app and then copy this and populate? Also I am not sure if Access is the best database, obviously I don't want people to have to use Oracle of SQL as this would require server configuration etc. but are there better free databases out there?
