.net - Retrieve Strings Via Reflection And Concatenate It Condescendingly?
Jun 28, 2011I have a long string that has been divided into lots of smaller Strings using the following pattern:
Public Class Test
Public Prefix_1 as String = "1 to 100 bytes"
Public Prefix_2 as String = "101 to 200 bytes"
[code]....
And this Test class has been compiled as class library project (i.e. a .dll file) and saved to C:Test.dll note that I have no prior knowledge of how many Prefix_ string existed in the dll file.My question is: How to retrieve all strings that start with Prefix_ via reflection and concatenate it ascending-ly (i.e. Prefix_1 & Prefix_2 ... ) into a single string?

[String].Join To Concatenate HTML Strings
Mar 21, 2009Is there a way to use [string].Join to concatenate html stings including spaces? I want to join html strings with a special character so I can pass them as an array to javascript from the code behind.

ArrayString = [String].Join(",", Array)
This works great if each item in Array is one word only, but what if each item in Array contains spaces?

It seems like you can only use integers for the underlying values.
VS 2010 Get The Text Between Two Strings?
Sep 28, 2011I 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 Create Objects From Strings?

VS 2010 Drawing Strings On A New Image?
Oct 18, 2010My 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, 2012I 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?
Mar 14, 2011This 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.
