Find A Matching Line ?
Aug 19, 2009
Have text file with two parts
[CODE]...
The upper part and the part after the line *+*+* Top *+*+*. What i must do is i must read the value in () at the Top part and compare that value with value in [] from upper part and write it side by side
This is my code so far:
Private Function GetLineMatch(ByRef LineToMatch As String, ByVal LineNumber As Integer, ByVal FileContents() As String) As String
Dim value As String = System.Text.RegularExpressions.Regex.Match(LineToMatch, "([d
[CODE]...
If u see the highlighted value are same. But from top part when it read (2 13.50 26.3)it only matches for one time the value in [2 13.50 26.3] so it take the first line and write and iqnore the second line.

The application must have basic functionality as to: Insert new customers into the database A search function will be needed to find a users criteria entered The more advanced features would include matching certain criteria with another for example if the data in field 1 is the same then it should match this and return the results. so for example if a person has a hobby of 'football' it will return all the people with the same hobby

I am using this code:
[Code]...
It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?

I am trying to save details from my program into a sort of mini database using excel, my program isnt having a problem opening the excel file, it is having trouble inputting the data. The first problem i would like help with is maybe a loop of some sort to get my program to look through each line on my excel spreadsheet and find the next empty line so it can input the data.
I was having some help from another person who gave me some code which go's to the very bottom cell and goes up until it finds text and then off sets by 1. However this was in the form of a macro, and I need a way to do it from my program.

I am suing VB 2008 express edition.
I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.
[URL]
In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

I'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.

I want to drag-drop single text items from ListView-A to ListView-B (both are in Details mode), but can't see how to read (and hence highlight) the index of the line in ListView-B when the mouse is hovering over it. Easy in a ListBox, but the PointToClient > IndexFromPoint features don't work with ListView controls and I just can't see another way .
