I wrote a program that uses the system.io namespace.It parses through files in a folder and renames them. It does so in such a fashion that it could create dups.
Dim di
As New IO.DirectoryInfo(fbdBrowseFolder.SelectedPath)

View 3 RepliesI'm having trouble many PDF files in the order that I send the print command using the following [Code]
It prints just fine other than it not being in the correct order. The only way I managed to get it in the correct order is by adding a timer and checking to see if there are any jobs in the print queue, which really slows down the printing process, especially when creating 500+ print jobs.
I was wondering if there is a better way to print these files, to where it will print fast and still be in order. A couple things I have in mind, but not sure if possible, is to create a text file or XML file that has the list of files to print and the quantity and queue the printer off that list or to convert PDF files to XPS documents and then using PrintQueue class to add the XPS file as a print job.
The code uses dynamically backgroundworkers which all workers great, but with one problem. If you were to look at line:
For Each folderPath In File.ReadAllLines("file path here")
You would see that it loops the text file, and starts background work.
The problem is that it does not list the files in order.
For example were you see "file path here" that were you put the file path.
The text file itself would look something like this:
C: est
C:VB
The program starts listing file from the C:est then goes back to C:VB then back to C:est.
I know the reason why, but I can't stop it. I tried pausing that code inside the loop, but with no luck. How would be able to list the files in order?
vb.net
Private filePaths As New List(Of String)
Private workers As New List(Of BackgroundWorker)
Private Sub GetAllFiles()
For Each folderPath In File.ReadAllLines("file path here")

For a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.
After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.
I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.

Basically I download lots of TV shows and they're never named in the way I like; they're named like this "The Office.S06E22.HDTV.XviD-NoTV."So I was wondering if I had a .txt file with all the episode names I could make a program to rename all the video files in the right order so they're named like this "The Office Season 6 Episode 22 - Secretary's Day."So I want to copy and paste a list of correct episodes names into a text file. Then I want to read the text file, which I already know how to do. Then, and this is the bit I'm struggling with, I want to read the text file, one line at a time, and it renames the top video file with the top episode name and so on.

i got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
I am attempting to create a basic program and I need to know how to incorporate INI files for profiles in order to quickly pull up data from one person to the next.
Public Class IniFile
' API functions
Private Declare Ansi Function GetPrivateProfileString _
Lib "kernel32.dll" Alias "GetPrivateProfileStringA" _
[code]....
And placed it into a module, which I then wen't to my main program and attempted to place this:
Dim ini As New IniFile(Profiles.ini)
Dim value As String = ini.GetString("Names", "1", "Default Value")
To attempt to retrieve the data, but I get no error or information from it. The ini file is inside the folder of the project and I set the SectionName and KeyValue to the corresponding names. I think I am having trouble with syntax? Not 100% sure. This is the code that I got from the same source as the module for using the module.
Dim ini As New IniFile(FileName)
Dim value As String = ini.GetString("SectionName", "KeyName", "Default Value")
And I adjusted to what I believed would be the proper format.
I have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
This might not be so 'VB' as it is 'SQL using VB' I have an application with a built in MS Access DB.

This is all done through the website, but when I search for ProductID 331 and click on it, it goes to the error page that says Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
It doesn't make any sense to me that the website would error with only this one product. This is the statement I am using. Does anyone know why 1 product would be causing this error?

I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view.
