Insert Row At A Specific Point In DatGridView Control?
Mar 29, 2010
I have a DataGridView control which is NOT bound any underlying data table. When the user selects a row (multi select is not enabled), I want them to be able to click an "insert" button to insert a row into the table below the selected row.I can insert a row at a specific location with the code below, and it will insert a new row at the location specified. My problem, is that I need to get the currently selected row and add 1 to it. However, the insert method below accepts an integer, and I cannot figure out how to get the currently selected row as an integer. I can only get it as a Row collection, which does not help. Can someone tell me how to get the currently selected row as an integer?[code]
I'm using the xmldocument class and I need to check in an RSS document if it includes the optional tags for a news item document. The two main ways that gets passed if via a <dc:creator> tag and an <author> tag below an item tag./rss/channel/item/?I'm new to this. I'd like to see if either of those tags are there, and if them and if not supplant it with something else.Right now in my code if I call /rss/channel/item/author and it's not there I get an error that dumps me. How can I test for it being there before I try something like:
Dim nodes As XPathNodeIterator = navigator.Select("/rss/channel/item/author")
I have created a program in which I am supposed to add a stock to an existing table of stocks. I have this table of stocks stored in a file. The last line of the file is a ------- and the final stock is on the second to last line. HOw do I add a stock before the ----- and after the final stock??? I can't use append because that simply adds to the end and after the ---.

I've searched the forums for this, but I can't seem to find exactly what I am looking for. I have a form currently that allows me to open a photo in a picturebox. I would like to add functionality that would allow the user to click on a specific part of the photo and add a point overlaid on the photo. This point would be the graphical representation of comment that they will enter in a separate text box. I am stumped on how to even start to get this done.
I have a small "options" form that when shown, the user submits some changes, clicks a button, and then it fades out. I want the form to open at the mouse location. How would I do that?
I have a picturebox that the user can draw on and I need the program to detect if a specific point has been drawn on. For example, I need the program to detect whether the user drew at location (8,8) and give a basic True/False answer.

I want to rotate a graphic at a point and I used the centerX and centerY to define the center of rotation. Here is what I wrote:
Dim rotate_mirror as new RotateTransform(CSng(txtbx_rotate_by.text)) rotate_mirror.centerX = 5 rotate_mirror.centery = 55 blk_mirror.RenderTransform = rotate_mirror
blk_mirror is the graphic I want to rotate. Unfortunately, It does not work.
I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right
I have the first part done, ... I can delete all the text before spacific text, ... now I need to delete all text after a spacific point in a string of text.

here ya go, check it out.

My application is in VS2008 coded in Vb.net. I have a datagridView which is getting populated from the Database.I has RegNo,RollNo,Name etc fields.The data in the Name column of database is coming from 3 columns of a certain table from database. This is how im concatinating it and displaying in datagrid.
My issue is i want to save this data in some other table which also has Surname,FirstName,LastName columns in the database. Im not able to split the column data present in datagridview cell into three fields. For Example:Name column in datagridview is having Name : Sachin Ramesh Tendulkar. I want to divide this string into three like : Sachin for Surname,Ramesh for First Name,Tendulkar for LastName.

I have lines like above in my text file. I have write all this value in another text file by adding the title. In my original file's line I must check whether the line contain any MIL value if not, I must write first T1 the below T1 I must write all the line which not contain MIL value until I reach a line which Contain MIL value. If the line contain 39MIL the I must write first T5 then followed by all the line which contain 39MIL until it reach the line which contain another MIL value. Let say 50MIL. the I must write T7 then followed by all the line which contain 50MIL. I sort my original file already. so the original file will start from the line which dont have MIL to 39MIL,50MIL,75MIL and 100MIL.
