I have many strings in a two column text file. The first column is the start position, the second one is the string.
[Code]...
The second column contains 100 chars.Obviously these strings have overlapped, if a start position is given and the string length is given. How to merge them together? Ex, I want start point is 38781735, end point is 38781900. The string length is 38781900-38781735+1
i have a multiline textbox and it add a load of info to it.
What i need is for it to remove all strings befor the : char.
For example if the line was this: this is just an example : hi there how are you ?
it would remove all befor the : and be left with: hi how are you ?

i have 2 string arrays and I want to merge them together then put the elements into a third string array ..
for an example :
string1="a","b","c"
string2="d","e","f"
after merging:
string3="a","b","c","d","e","f"
Say I have a listbox, and the items in the listbox look like this:
#COLORS#
GREEN
BLUE
BLACK
#NAMES#
BOB

#ETC#
How would I make it to where when a user clicks a button, all the text between #COLORS# and #NAMES# is removed? Let me know if you need more detail

I am working on a UDP Client/Server, and currently i have them sending back and forth strings, which i convert to bytes, and then open the bytes to read. I want to now send an Object instead of those strings, which includes multiple unsigned integers and strings.
View 39 RepliesI'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'm trying to overlap two images. I've got this part working, next I needed to make sure it wouldn't carry on overlapping one image. So I did this:
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
Dim ActualBrick1 As String = "admin_block.PNG"
If Minage.CurrentBlock.Contains("wire") Then
MsgBox(ActualBrick1)
[Code] .....
There's the function. When the file name doesn't start with "wire" it says the correct file name. But if it has "wire" in the name it just makes a picture with the preset file ("admin_block.PNG"). Even if the block under it has been changed.
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?
View 2 RepliesI need to overlap two images. When overlapped at the correct point, the overlapped portion of both images match exactly (or very closely).Now, I have tried to match the color of each pixel in the images, then move one image a bit and match them again until I get a high match rate, usually 95% or higher. The issue is, this is ridiculously slow. Also, I can't find a way to check the pixels if one I need to check a negative co-ordinate.

I'm trying to automate the process of logging into twitterfeed.com, and filling in the information (the feed url and twitter username are pulled from textboxes). I had it mostly working the other day, even if it is a bit sloppy (the only way I could get one button to click is to send 50-some tabs). However, lately it seems to enter in a sort of loop. When I pause the program, Visual Studio indicates that it is the Application.DoEvents in the Private Sub "wait" that is still running even after it should be.

I've got a list of System.Drawing.RectangleF objects that all overlap the same RectangleF object.In my picture below, the 3 overlapping rectangles would be the pink, yellow, and red rectangles.My main rectangle in question is the light blue rectangle.
Second Image: I know that with RectangleF objects I can use the Intersect() method that will return me another RectangleF object representing the overlap. But as far as I can tell, this only really works when comparing two rectangles.
My question is: How could I determine the TOTAL area/percentage (i.e. the combined total overlap of the red, yellow, and pink rectangles when compared to the light blue rectangle - but it would need to be smart enough to not count the area in which the red and yellow overlaps twice, and same for the pink and yellow)?
NOTE: The green lines represent the area I'm looking for, just the total area of the blue rectangle that is not visible.
UPDATE: I've added a 2nd image to further demonstrate what I'm looking for. In the second image, the presence of the burgundy rectangle should have no affect on the total percent covered because that area is already covered by the yellow and green rectangles.

This is a followup to the question I asked here:

I understand the answer in the post above, which is absolutely amazing, by the way. It's about implementing interfaces with a class. However, what if a class needs to share features with another class?Yes, that class can an Interface. However, let's use this sample definition.
[code]...
Or, in other words:An equippable item can perform acts outside of its typical usage of a shield or weapon. But not all items can act as a sheid or weapon.I mean, I could create a class that implements IWeapon, IShield, IMagic, IUseableItem, etc. But there should be a better way than returning NULL when those interfaces are called.

View 2 RepliesI have two text files. The first text file has the format:
ID h1 h2 h3
a 1 5 7
b 3 3 5
c 0 4 8
And the second file:
ID h4 h5 h6
a 2 4 9
b 3 6 1
b 4 1 5
Now I want to merge two files. The output likes
ID h1 h2 h3 h4 h5 h6
a 1 5 7 2 4 9
b 3 3 5 3 6 1
b 4 1 5
c 0 4 8
The two files has the same rows and columns. For the first rows(except header) in the two files, they have the same first column. Therefore just a simple append. The final first row becomes
a 1 5 7 2 4 9
The question is in the first only has one
b
and the second file has two
I want the maximum count of items from each list in the resultant list. I put some white spaces after "b" then append strings.
b 4 1 5
For key "c", because it is only in the first file and not in the second file, so I append white spaces after the corresponding strings.
