VS 2010 Replacing Content In A List?
Jul 19, 2011
I'm currently in a "course" (mostly self taught with some guidance) and I'm hitting a wall in one of the tests.
The idea is to read out a text file, loop trough the list and replace the content if the item from the text file is found in the list. I've got it fixed up until the replace part:
Dim SplitFirstCase(3), SplitSecondCase(3) As String
Try
FileOpen(1, "orders.txt", OpenMode.Input)
[Code]....
The loop works, but it seems that splitting the selected object isn't allowed. Value 0 is the article number, and based on wether the value returns or not the selected object needs to be replaced.

I am writing a Macro for an Excel spreadsheet that copies cells out of a separate file and pastes them into the open workbook. Some of these cells contain the error #DIV/0. I need an if statement to replace all copied cells that have the error #DIV/0 with the value 0.

I have a file that is constantly altered, and if an error happends, I want to have a backup. I was wondering if there's a way to make a script that will copy all the files in the selected folder, and post/overwrite them every 20 minutes in a back-up folder or something, and I say overwrite so it doesnt take up 298347234 gigs of data.

For example:
Text = Unicode --> Unicode character

This is an example of the text I want to modify:
0110
0001
0001
1000
[Code]....
Here, I want to replace two-line digits in bold(0110 0001) with a different sequence as the program scans the text line by line. But two things complicate the task:
1. the comma lines should be ignored, but
2. they also should stay intact after changing the digits.

I have the following multithreading function to implement threads fetching from a list of urls to parse content. The code was suggested by a user and I just want to know if this is an efficient way of implementing what I need to do. I am running the code now and getting errors on all functions that worked fine doing single thread.for example now for the list that I use to check visited urls; I am getting the 'argumentoutofrangeexception - capacity was less than the current size'/Does everything now need to be synchronized?

I have a folder named test. In this folder there are 3 folders(u_test1, u_test2, u_test3). And in this 3 folders are some files.
Now I need to transfer the folders u_test1, u_test2, u_test3 and the content of the folders to a ftp server.
I have tried the following code, but with this I can only upload a single file.
My.Computer.Network.UploadFile(sourcepath, "ftp://" & global_destination, global_username, global_password, True, 500, FileIO.UICancelOption.DoNothing)

1)This is my code.. (below)what i am trying to do here is to insert username and confirmed password into a sql table called login via a pre created form.I have 1 textbox, 2 Maskedtextboxes and a button.
what i would like is if the passwords do not match in both maskedtextboxes for the system to throw out a message saying passwords do not match please try again..which then clears previous content and requires the user to enter details again. once details are correct and system commits the new user details to the table and throws up a confirmation message.

I have an issue here, lets say I have this string: "Lets create a database called 'farfromwest' and then host it" And I want to change the substring that is inside the ' ' with "nearwest", how can I do it? "Lets create a database called 'nearwest' and then host it" Remember, I want to change what is inside ' ', this means it could be any word, not just the one of the example!

I am trying to create a console application that allows me to read the contents of a text file and saving the data by specific name in a set of files. For example, the text file I am going to read is a tab delimited file. Some content of the file includes full name, school, location, and whatnot. I want to save the content by school name in a set of files that have the school names. In this case, everyone that attends "Central" will be saved in a file named Central.txt.Everyone that attends "Central Park" will be saved in a file named Central Park.txt.These are the sub procedures I came up with so far:
Readfile()
'Use StreamReader
WriteFile()
And I think I am on the right track of reading the text file:
Dim objStreamReader As StreamReader
Dim strLine As String
'Pass the file path and the file name to the StreamReader constructor.

Im learning Visual Basic 2010 on my programming class and we reached the part of file handling. Here i tried to make a simple program that can create a text file with the content of what i type on the textbox, basically i create the file if it doesn't exist, and if it already exists i append the content to it. Once the file is saved i can read it using the "Open" button. Unfortunataly, whenever i try to create the file, the compiler gives me an error saying that it cannot modify a closed file, although i've followed up the execution instruction by instruction and i can't find the error.

I'm storing images in a List Of Image. When I want to clear/remove all the images it contains should I dispose & set each item to nothing before using .Clear? Or can you just call .Clear? I'm doing it like this for now...
' remove all images in list of image named "images".
For i As Integer = 0 to images.Count - 1
images(i).Dispose()
images(i) = Nothing
Next
images.Clear()
