Finding Single File Using Wildcards?
Mar 3, 2012
I'm using Visual Basic Professional 2010, I have two directories of XML files. The naming convention in directory one is a user's name, a six digit date and ending in ".xml_CREATE.xml". So, I perform some work on a file in directory two. During the course of that processing I discover that a file exists in directory one called "Mike" an unknown six digit date and ending with ".xml_CREATE.xml", so while I have no way to know the date, I know it exists and would look something like Mike030312.xml_CREATE.xml. So, now I want to load that file as an XElement that I will eventually incorporate into an XDocument, so I need to perform a Load similar to:
myXMLFile = XElement.Load(My.Settings.XMLDir & "" & Mike030312.xml_CREATE.xml),
However, since I don't know the date, I need to insert wildcards at that spot. How do I make that happen?

i am pulling data line by line from a PPML what i need to do is: If "current line" matches my string then write that line to a new file
that part I have down my only issue is, is that the "current line" has filenames with in it that change constently i would like to be able to do something like a string with wildcards in it : "<currentline>src=""*""/>" but this does not seem to work Do i need to do an index with conditions or is there a different way if i do need to do an index how would i go about doing that in vb .net for studio 2008

I am using a database in Visual Basic 2010 displayed through a DataGridView. Through the DataGridView's "add query" option, I am writing these queries. My goal is to have partial search entries show up (ie if the entry is "Lewis" then it should be among the entries returned if "Le" is in the textbox.)
SELECT * FROM Table WHERE Surname LIKE '%' + @Surname + '%'
I am using the above query and it only returns exact matches despite the LIKE operator. Partial entries never show up despite the presence of the wildcard % symbol. It's as if the whole thing is being treated as an equal sign.What should I do? Is it a problem with the SQL itself or does VB's "add query" maker simply have such limited capabilities?

i have a bunch of radio buttons which can have different text displayed depending on whats retrieved from the database.however i want to add code that hides any radio button that would have a 'zero' retrieved from the database.so far this is the code i was coming up with, without getting into the nitty gritty of the actual database queries
If RadioButton1.Text = Me.HWExamsDataSet.DSExamTextA.Rows.Item.tostring = 0 Then
RadioButton1.Visible = False
End Ifabase entries or queries.
it looks like it may work...but is there a way to automate it so that i can put in a reference to ANY radiobutton like radiobutton(*).text? or a bunch of buttons if need be.i know theres a way to specify additional items to a given command...just can't remember if its curly brakets etc.

how to even start a code project of this sort but here it goes... I have an external Hard Drive with some music. My itunes makes duplicates of all my songs so this is what i have.
Dance.mp3
Dance 1.mp3
Dance 2.mp3

Party.mp3
Party 1.mp3

What I want to do is have the program search the files and delete all files that have a duplicate with a number behind it... Now I would use windows search but some of the songs are like 1001.mp3 or 1001 1.mp3... I want it to look like this when i get done (from the above):

I will have a directory of files (IFO, BUP, and VOB; DVD files for anyone who cares), I need to find the first one by sorting these like this: Filter out everything that does not have a .VOB in it, then find the one like this VTS_**_1.VOB. It will always have a "1" before the extension, but the two numbers before that change, lastly I need that file returned as a variable.

Is there a better way of finding the path of a file that was opened with the open file dialogue? This is what I did. It works, but it seems like there should be a way to get the path through one of the open dialogue options.
Code:
'm_PicSource = OpenFileDialog1.FileName
'm_PicSource is a global var
Dim strCnt As Integer = m_PicSource.Length - 1

This is just a simple example. I'm trying to make it so that if one x.text = ru*** (for instance, ru---, or ruuuu, or rux2x, etc.) to have x.text change to a predetermined value (hardcoded).

I want to perform two hashing operations concurrently on a single file, without reading the file twice. Is there some way to share the FileStream between two synchronized hashing threads? For example:
Dim Stream As New IO.FileStream("...", IO.FileMode.Open)
Dim HashA, HashB As Byte()
Dim A = New System.Threading.Thread(Sub()
[code]....
Maybe some way of caching a stream? Trouble is, I don't want the entire file in memory at once (it could be many gigabytes in size) and I don't want the file read more than once, due to speed issues. I want the file cached only sufficiently to ensure that both threads can work.For example, suppose at some point in time, thread A had read 100k of the file, but thread B had only read 20k of the file. The portion of the file between 20k and 100k should be cached; but then progressively forgotten as thread B catches up. Then again, if thread B is too slow, we might still end up with hundreds of megabytes being cached.Maybe thread A should be made to wait while thread B catches up. Maybe the ReadByte() function of the stream should block for a while if one of the threads is too far behind?

I need my published vb 2008 application to open a helpfile that I wrote. It is a simple .txt-file and this piece of code does the trick as long as the program is not published because I already know where I placed the Helpfile:
System.Windows.Forms.Help.ShowHelp(Me, "C:Helpfile.txt", HelpNavigator.TableOfContents)
After it is published on another pc, the helpfile is not on the root of the c-drive but in the application folder of the program. However, I can not know where the path to the program folder of someone else's pc is. It all depends on where they decide to place the program when they install, right?
It seems I need to replace this little: "C:Helpfile.txt" with some code that searches all the drives and directories and/or points directly to the Helpfile's placement - i.e. the parent directory of the program.

I have this pretty simple application, it uses a webService to transfer data to my servers DataBase. Now it is very important for me to keep this application as one single file, and not having some XML files needed for it to work, but this is the case. I think the XML file holds the information to this webService, so without it the application crashes. Is there a way to get the application to work without this XML file, or a way to put the XML inside the exe archive?

I've been doing a lot of coding latley and I'm interested in some things that vb can do. I was wondering if vb has the ability to search a directory for a file or mutipule files within a folder. Like in dos I can do C:user*.* and I can get all files that have . in them. Is there a similer way to do this in VB, I don't think VB has a wildcard or I've not heard that it does so I'm comfused on how I would find a file if I didn't know the path.

This works fine for getting the wave file info, It just doesn't display the numSamples which I need.

I am working on a program that opens a .txt file, finds the length of each line in the file, and then outputs the minimum and maximum lengths. For example, assuming this is the .txt file I am opening:
2789304
293048203
27598493
[code].....
I would like to return something like this:
Minimum length: 6
Maximum length: 9
I cannot use arrays for this assignment. I figured out how to get the maximum length but cannot figure out how to get the minimum. Am I going about this the right way or is there an easier way to do this? Here is what I have thus far:
Dim FileName As String
Dim FileReader As StreamReader
Dim FileLine As String

I am taking a VB2008 class and I have the entire program figured out except for one thing. I've checked our text I've scoured the internet and I've tried tons of things.
What this section of code does is access a data file, calculate the average from it... done.. that works, calculates the highest number in it... done that works... and calculate the lowest number from the file... nope... not working. I've tried tons of things and what i have in there now keeps giving me an output of 0, when it should be a 2.

Well I've recently discovered that trying to create a file with so-called 'illegal characters' will cause your application to crash.. How do I find these characters in a string and replace them with nothing?
The invalid characters are / : * ? " < > | if that helps.
