View 11 RepliesThe address I need to read is a java servlet that processes parameters passed in, generates a text document on the server, and then redirects to another URL and returns the address of the text file on the server. I then need to download that text file and process it. I'm having problems connecting to the first URL with the parameters and I think it has to do with the redirect.
I'm using the WebRequest object and I've tried using the HttpWebRequest object. Are there any other objects that support redirects?

Does Anyone know How to read multi-line strings? I am using XmlWriter to write a Multi-Line Textbox to an Xml Document. The Trouble Is I can't figure out how to get the reader to read that multi-line element. I know the writer is writing it in multi-line, but the read just squashes the lines together. Does anyone know how to read that multi-line element properly?

View 9 RepliesI need to read strings by stream! Is this possible? I've been searching for quite a while now, without results.So what i have is an application which gets song lyrics. The lyrics come in a string and i need to separate the string into multiple lines. Just to make that clear, lets say that im getting this text and put it into a string:
Bla bla bla..
Na nana na
And in string format = "Bla bla bla... Na nana na" but what i need to do is separate them into its original, line by line.I created an for each loop which looked for upper chars and when found, create a new line. But that didn't work out so well since the lyrics are written in proper english, using the upper "I" everywhere. So i created a new loop which ignored "I":es if they were followed by a space/blank " ". That didn't work either, it skipped some sentences.
Say I have a List(Of Tag) with Tag being an object.

I have a situation where I have a vb.net program that uses two connection strings. This program will be used on multiple web servers on multiple domains and the only difference for any of them is the two connection strings.What would be the best solution to read in these connection strings from a file separate from my actual .vb code?
Ideally I want to be able to drop the .vb and the connection string file into its own folder on any number of asp.net websites and not update anything else (for example add any connections to the web.config or anything) than the external file containing the connection strings, I assume something like xml would suffice?

I'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).

I'm having problem reading Binary file that has two types of data in it; Strings and numeric data in decimal format.[code]...
1. The loop doesn't stop, and it gives me "Unable to read beyond the end of the stream" Error..
2. The output isn't accurate, apart from a few random correct strings and numbers..
3. After the loop is fixed, how can i save the data to an Array or write it to a text file?. Can the be saved line by line so that the output file has the same number of lines?
4. As you can see in the code, I've tried writing data in a file, but it doesn't work.. Messagebox does show some data (even though it's not accurate), the file however doesn't contain any data..
i am working on a project where i select from a list box what entry i want to change (out of a set of 27)and then i have to select the entry, enter the details in the text box, hit ok and then i was trying to make it store the string it made under a deceleration.

View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I have been looking for examples to find the string between two strings. This top one works fine;

Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 2 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable
