View 3 RepliesAm writing a windows app using vb.net 2005. The app captures a string variable from the user. As each file within a directory is read, I want to match the stored string within each file. If I find a match to the string, I want a list box to be populated with the name of the file. I have added Imports System.Text.RegularExpressions and tried using the match collection.
For example: My direcotry has 5 text files. I want to match a string "PARENT" in the text of all these 5 files. The list box should output the name of each file where the string was found.

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.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo

However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.
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?

View 5 RepliesI'm trying to include a few text files in my project. These files are read and used to make decisions in the program. Ordinarily, I would just set the file path and open the file via StreamReader, no problem. However, this application now needs to work on other computers and I want to include the text files in the application directory. I've researched two ways to do this:
1) Include the files as resources and reference them via my.resources.
I've gotten this to work ok, except the files are opened as strings upon starting the application. They are fairly large files, which I imagine is taking a lot of unnecessary memory. Also, StreamReader wont work with these files as resources,
or at least I can't figure out how to. My application is already based around using StreamReader so I don't really want to change this.
2) Include the files as additional items. I know how to do this too, but I can't reference the files programmatically.
Can I use a resource text file via StreamReader or how would I reference the files if they're included in my project directory?

View 2 RepliesA variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
I have tried several solutions:
1) data.SaveToFile "/temp/"&filename, 2
Error: Object required: '????????????????????'
???
2) File.WriteAllBytes "/temp/"&filename, data
Error: Object required: 'File'
I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!)

Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Dim BinaryStream

This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.
All I am doing is reading each txt file I find in a directory and finding certain strings in the text then counting how many I find in each file and then once each file has its separate counts it send it to a sql database. I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files

View 4 RepliesThe user inputs a serial number in a form, the program searches a specified text file on the internet for that serial number, and if it is there then the program runs normally, but if not it exits. I already know how to do the trial part of this program and I know that this is not secure as someone could just hack it and find the text file and read the numbers, however this is for school and is not commercial. The only thing I need to know is how to search a text file for exact text that has been inputted by the user. I've been trawling the internet and I've heard of something called instr or something, but I'm not sure.

View 2 RepliesTrying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??
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..
