Loading File Info Properly?

Dec 27, 2009

I have setup a file that is comma delimited:

{object name,text,object name,text...}

I have loaded the file, split the delimited text into to separate arrays. One array is for the' object name', the other for its corresponding text.The text is no issue. My issue is that the 'object name' would look something like "form1.label1, form1.label2..." This loads fine, but I can not figure out how to get the 'object name' to be used as an object.I dimensioned the array for 'object name' as an object, but this won't work:

objectname(i).text = "..."

Looking at the values of the 'object name' array, after each listing it says {string}I need this to work this way because the file is loaded with the idea that it could be in any order, longer or shorter then another, etcetera.

Forms :: Speed Up Loading MP3 File Info Into ListView

Apr 27, 2010

It has the ability to recursively grab all .wmv and .mp3 files in any chosen folder, and add them to a playlist.When opening the playlist, my program adds all the songs to an array, then starts adding the songs to a listview, categorizing them by song, artist, album, and genre, using a dll to access the ID3v1 tags on the .mp3 file.It can successfully create playlists of thousands of songs at a somewhat okay speed, the problem is loading that into the categorized listview.It used around 75% of my friend's CPU while loading his 5k+ song playlist into the listview, and it never finished after loading it in for a couple minutes (it auto updates as it loads, because it is done in a new thread.) It never finished because his OS has a bug where, if the CPU usage is over 100% for more then a few mins, it BSOD's, but that's beside the point.

His CPU, by the way, is a quad core 2.33 GHZ processor.The listview loads thousands of songs by using a lot of CPU [low amount of RAM, less then 40MB 99% of the time], and it does it slowly. [code]I've already redone the sub once or twice to speed it up, and at the moment it's 2-3.,

VS 2005 AcroPDF Not Loading Properly?

Nov 11, 2009

I have a desktop application that shows a list of pdfs, and when the user selects one it shows it to him/her. I use the AcroPDF control for this, and it seems to work, but if the user goes back and forth between viewing the file and viewing the list, then the control randomly decides not to show the file (showing a blank page instead).

VS 2008 - Loading Form With Some Info

Apr 16, 2009

I want to create a form that, when starting, will display in a ListBox the content of a txt file. I know the file is read because I can display the content in a MsgBox. Here's a snippet of what I tried so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim filein As String = "MyProjects.txt"
Dim objReader As New System.IO.StreamReader(filein)
ListBox1.Text = objReader.ReadToEnd
objReader.Close()
End Sub
When I debug my app, ListBox1 is empty.

DB/Reporting :: Writing A Program And Loading Info Into A SQL Database

Feb 17, 2009

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

Writing Info To And Getting Info From .text File Using A ListBox's Display

Cannot Read A File Properly?

Feb 22, 2009

I'm in need of a simple Regular Expression that will match all strings that start with the string "textures/". The problem probably is when to end the match.

Here is an example of the type of file I need to parse:

[Code]...

I have attached an example file (it's from a game, and it's a free game, so I don't think this is not allowed?). When opening that with Notepad I see loads of spaces and a few strange characters. When opening it with Wordpad, I see mostly strange characters (but the "textures/..." strings I need are still there). When reading it with VB (IO.File.ReadAllText or using a StreamReader) I cannot get it to show more than a few random characters, and the "textures/..." strings are no longer there...

File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Get (music) File Info Based Off Of File Path?

Jul 24, 2010

I'm working on a personal project and so far everything is going perfect. Almost. I have a problem with getting music file info based off of its file path. I.e. "

C:UsersUSERetc." The only things I would need from y'all would be how to get the song's Artist(s) and Name (maybe there's something similar to 'AxWindowsMediaPlayer.currentMedia.getitemInfo("Information")' without actually having to play the song?

After I get this information, I would like to know how to add it to a ListBox as this: "[Artist] - [Song Name]", but I can do the text part if I know the getting-the-information part and adding-the-info-to-listbox part.

How To Properly Serve XAP File From Self-hosted WCF Service

Jun 12, 2011

I have myself a self-hosted WCF server setup, which serves a clientaccesspolicy.xml and an index.htm which is just points to my xap (accessible via app.xap).

I'm currently serving them via the following code:
Public Function GetPolicy() As System.IO.Stream Implements IClientAccessPolicy.GetPolicy
WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml"
Return New IO.MemoryStream(IO.File.ReadAllBytes("Server Files/ClientAccessPolicy.xml"))
End Function
Public Function GetIndex() As IO.Stream Implements ISilverlightServer.GetIndex
[Code] .....

It works, does the job I'm after. However, I don't think this streams the xap properly, and I know it's a streaming type. If this isn't streaming it properly, how should I stream it? (The endpoint that the XAP and index.htm files are coming through has a webHttpBinding binding). Is it being streamed properly? Or should I make some changes?

VS 2008 Using The CommandLine Arguments Properly To Open A File

May 5, 2009

I am trying to use the Command Line Arguments during the Form_Load event to load the file a user might have selected in windows explorer.

I have set some file associations during setup, so that any ".script" files will be associated with my application. However, my application can also open other (text based) files (it's a text editor), and I would like the user to be able to use "Open With..." and select my application to open the files in my application directly.

I have to use the Command line arguments for this, which will hold the filename(s) of the selected files, correct?

So I did this:

vb.net
For Each arg As String In Environment.GetCommandLineArgs()
If IO.File.Exists(arg) Then
OpenFile(arg)
End If
Next

Now, when I open a ".script" file, my application opens and the correct file is loaded. However, in addition, the EXE file is also loaded for some reason! It has opened two files, <Applicationname>.EXE and the file I wanted to open. Because the EXE file is obviously not just a text file, it just displays some random characters, but I don't want it to open that of course...

Also, if I run the application in the debugger (visual studio), it opens the <ApplicationName>.vshost.exe file... So I thought, I can check for the extension of the argument, and only open it if it is a ".script" file. BUT I don't want that! I also want the user to be able to select any file and choose Open With... and select my application. That won't work if I check for the file extension...
