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 just couldn't figure out how to datagridview works with if else statment.
View 2 RepliesI've figured out a way to load a php file and then search and replace if it contains one of the following:[code]Is their a way where I can load the the php file and also load a txt which contains the string i want to replace, so the exe dont actually save the txt.Replace. This way the user of the app can define the contents of the search and replace and it wont run out of memory.
View 1 RepliesI 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?

I'm trying to make a program (in VB 2008 Express Edition) that will take text (from a textbox) and then switch the letters (say a->f and A->F) and will put the result into a second textbox when I click a button. How do I code the program so that it will search through the textbox and find all of a certain letter (say a) and replace it, then search for the next letters (say b-z) and replace them?

I want to change
If strErrorMessage.Length > 0

and any other similar call to the Length method from a string to the following
If Len(strErrorMessage) > 0

I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
