Oct 16, 2009

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

Asp.net - Split The Filename So That Can Put It Into 3 Separate Strings?

Apr 12, 2012

I am uploading files to a directory and I am also just getting the file itself not the directory and the folders. For example I am getting only this 6122002_Abstract_9-11-07.pdf by using this code hpf.FileName.Substring(hpf.FileName.LastIndexOf("") + 1). What I want to do is separate out the 6122002, the Abstract, and the date which is 9-11-07 so I can insert it into a sql database.

Separate Strings In Text File?

Dec 16, 2009

I am reading a text file in which has three colums of information i.e.

00100 25690 21586
23510 25694 24856
25896 45478 52897
58745 59687 12364

I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.

Prepend A String To All Strings In A List Of Strings?

Aug 5, 2010

I 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))

[code].....

It works, but I would rather use built in functions whenever possible.

VS 2008 Using List Of Strings Or Array Of Strings?

Oct 16, 2009

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?

Find Strings Inside Strings?

Aug 15, 2011

I have been looking for examples to find the string between two strings. This top one works fine;

Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)

[Code].....

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?

DataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings

May 14, 2009

I 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

VS 2010 Get The Text Between Two Strings?

Sep 28, 2011

I guess my question has two parts:

1. My program has to read text out of a text file. I use some HTML tags to preserve the formatting. For example, I might have the line "this is a <b> line </b> of <b> text </b>" where "line" and "text" are bold. How do I make it so the string prints to a RichtextBox, but only "line" and "text" are bold? I would use a RichTextbox.SaveFile method, but the program works by reading a group of richtextboxes in a flowlayoutpanel and appending them to a single text file.

2. How would I extract the text from between two strings? For instance, I have created special tags for use in my program. These tags tell the program where to add controls. Say my string was:

"[IMG= "dog.jpg" /] this is a picture of a dog. [IMG= "cat.jpg"] this is a picture of a cat."

For each occurrence of the string "[IMG=", I would need it to find the corresponding "/]" and extract the text between the two. I could maybe do something with a substring function. I don't know.

VS 2010 Drawing Strings On A New Image?

Oct 18, 2010

My goal is actually very simple: I simply want a (shared) function that accepts a List(Of String) which creates an image and writes those strings (line by line) onto the image. There's a bit more to it than that, but for the sake of example this is all you need to know.Usually when drawing on an image I would create a Bitmap object and get the graphics object from Graphics.FromImage:

Dim bmp As New Bitmap(100, 100)
Using g As Graphics = Graphics.FromImage(bmp)
g.FillRectangle(...)

[code]....

Seems easy enough, but the problem is that I don't know how many strings there will be in the list, nor how long they will be. The image should 'scale itself' according to the strings in the list. If the list contains 5 strings it should be 5 strings high (plus a little extra for borders). If the list contains only 1 string it should be only one string high. Same goes for the width, if the longest string is 150 pixels, the image needs to be at least 150 pixels (160, 170 or something).

This is all good, I can get the dimensions of the strings by using Graphics.MeasureString. The problem now is that I need the dimensions of the image to create the bitmap. I need the Graphics object to get the dimensions. But, I need the bitmap to get the Graphics object I'm stuck in a loop here, if I don't have the Graphics object (I can't create it from nothing..) then I cannot measure the strings, but if I cannot measure the strings then I cannot determine how large my image will be, so I cannot create a bitmap and associated Graphics object...

VS 2010 Make An Enum Of Strings?

Feb 20, 2012

I would like to make an enum of strings. There are several masks for text boxes that I would like to standardize in our system.For simplicity lets say there are 2 masks:

"PhoneNumber" which is "(999)000-0000"
"Zip Code" which is "00000-9999"

I would like to be able to reference these through out the entire program in a manner such as:

DefaultMasks.ZipCode or DefaultMasks.PhoneNumber

Since enums can not be of string type, what would your best suggestions be as to how I could do this. I had thought about a class with constants in it but I was not sure how to implement that properly.

VS 2010 Null And Zero Length Strings?

This is related to my last question.Even though Access considers Nulls and zero-length strings (ZLS) separate values, often developers wish to treat them as equivalent for the sake of an If...Then statement or some other stretch of code. One way to accomplish this is to write code like this:
