I am trying to search all sub directories for a symbol and replace it with another. The code below works for a specified path but it will not search sub directories.

one of the BIG hurdles in my simple project, making a search engine. I don't know how at all. The search engine need only to search in one Directory with its sub directories and txt files for criteria, and display the results, with option open from the results. any basic code or example maybe?

i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.

I have a VB .NET String. How can I search that string for a character string and replace it with another string?
For example:
Dim rValue As
String = sproc.ExecuteScalar()
' rValue now has the XML string <indracio fire height=23, width - 6>
/* This is the string that I want to search. Replace the words "indracio fire" with the word "lucion time"
How can I search this string for the words "indracio fire" , and replace with the word "lucion time" ?
I have a 133 Mb file which contains almost a million records. Currently, a user loads this file into KEdit (a great editor for working with large files) and changes occurrences of a dollar sign $ to blank and takes negative numbers represented as such with parentheses and changes that to a negative sign. That is, (5000.23) would become -5000.23. So the leading ( becomes a - and the trailing ) becomes a blank. I believe the only occurrences of ( and ) are around the numbers I want to change, so I don't have to worry about changing something that should have been left alone. Using VB.NET in Visual Studio 2008, is there a "painless" way to do this other than reading the file one record at a time and searching/replacing and writing the record out? While not really painful, I am worried about how long that will take (to run, not to code ). Is that a valid concern?
My long range goal is to automate many of the routine file preparation tasks my users do. We get an input file from 15 clients. The file can be in any format the client has chosen to give us, and it is our burden to reformat any errant fields into an acceptable format for insertion into our database.
I am trying to find or search record from a datagridview so I could replace it with a new data from a textbox. I used the datasource.find() method the only problem is...If the my Table consist only of one Row, the find method replaces that one row everytime i insert a data. I just couldn't figure out how to datagridview works with if else statment.

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.
I got some code that im try to make search and text file and replace it. The code im using to replace it with is whatever the user entered in txtURL.text. Here is what i have
Dim strFile as String
Dim result as String
strFile = "C:\test.txt"
oRead = IO.File.OpenText(strFile)
result = Replace(oRead.ReadToEnd(), txtURL.text, "1F.php")
oRead.Close()
Is this writing it back to the file also....I think that might be the problem, not sure..
I am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)
[Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()
Is there a way to look in a textbox for some text1 and then if its there, it is replaced by text2?

Basically I'm going to try and develop a software that merges PDFs automatically using the PDFSharp API.What I want in the program is to basically that: Have the program to give and Input and Output directoryMerge all the documents in the directory or sub-directoryRename the merged PDF file according the the name of the directory/sub-directoryIf the folder has PDF files and a Sub-Directory I want to merge the PDF files in the folder and rename them as per the main folder, and rename the files in the sub-folder according to its name (i.e. seperate|)
It's the first time I'm using an API.The problem I have is how to use the directories and sub-directories as I need them.
I have a large ASP.NET project where I want to do a mass search and replace (about 3500 instances)
I want to change
If strErrorMessage.Length > 0
If strSomeString.Length > 0
If strWhatever.Length > 0
and any other similar call to the Length method from a string to the following
If Len(strErrorMessage) > 0
If Len(strSomeString) > 0
If Len(strWhatever) > 0
Anyway to reliably do this in one shot?
I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0
This just won't work though as it won't understand how to rearrange it properly. Currently have VS2010 and N++ at my disposal.
I have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.
