I want to search for a string entered in a column of a datagridview in a text file.If this string exists in the file then allow the user to enter it otherwise dont allow the user to enter the string.Also,since I am reading data from the database into the datagridview, I have not added columns to the datagridview using edit columns option. How do I do this in vb.net.I tried doing something like this:
CODE:
I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

I am creating a Calender application using the monthly calender control.I am trying to implement a search for the calendar so a date can be entered into a text box which intern moves the calender to show the date entered. I have been try to figure this out with no luck, is it even possible to do?
View 2 RepliesI am building a search engine in vb.net which would have to search for a word entered by the user in 40 text files within the project directory. It should return the results as the total number of matches (text files) and the number of times this word is in each file.
View 5 RepliesThe format I need is a group of numbers in a text file and it looks like this and it will always look like this:xxxx x xxxxxxxx xxxxxxxxx x xxxxxxxxxxx xxxx x
The problem is that it can be anywhere in a text file so I cannot search by a particular line.
How can I search for this type of string format in a text file?
So I am trying to create a Win App to make copying files using Robocopy easier and eventually other tasks. Basically what I have so far is a Button that calls the Sub Robcopy_EXE. There is a tab on the form with 100 check boxes, one for each terminal, that will be designated by the user and a check box to determine if you want a detailed report or not from Robocopy. I also have a text box for the user to input the first 3 octets of the site IP Address. The check boxes and Input field are used to create string "Terminal_input" which is what runs Robocopy in CMD. Robocopy logs its progress to a text file that I have labeled "Status.txt". That is as far as I have gotten.

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.
I am creating a program which searches saved .htm files for the source codes. I get the source code and do manipulation on the code to pull the values I need into a datagridview.
Is there anyway to search a datagridview column to see if a value exists first, so no duplicate rows of data will be added? I was thinking of making access table and linking the datagridview to it, but i'm not sure how to set the database links up with code (other than the gui), and then still search the column so I don't put in duplicate rows.So far, I have only come up with the way to add the data row by row...
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Data in Table1 is as follows
Code-------product--------weight
1-------------Apple----------2.00
2-------------Mango---------3.25
3-------------Banana---------6.50
Then I have Datagridview with three columns same as
Code, Product, Weight
I have following codes
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
dt = GetTable(str)
If dt.Rows.Count > 0 Then
DataGridView1.Rows(0).Cells(1).Value = Trim(dt.Rows(0).Item(0))
DataGridView1.Rows(0).Cells(2).Value = Trim(dt.Rows(0).Item(1))
End If
End Sub
When I enter 1 in row(0).cells(0) then other two columns fill automatically, but when enter 2 in next row then nothing retreived from database.I think this line should me modified as current row and current column.
str = "SELECT desc1,weight FROM master where code =" & Val(DataGridView1.Rows(0).Cells(0).Value)
Is there a way to check if a column contains all or any of an items in a list? Example "ABCDEFG" is my column value. "A" "C" "L" is my list stored in a list. I need to find rows that contains at least one item in my list. Then items that contains ALL the items in my list (a basic OR / AND search such as a SE would have)

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

I have a dataGridView and a textbox on a form. I want to be able to search through the dataGridView and sort it compared to the string in the text box. Ex: I type "acv" in the text box and all strings containing "acv" are sorted to the top. I'm accomplishing this with a bunch of gymnastics involving datatable.select and some clearing and filling but it's ugly and slow.

I'm just wondering if it's possible to display a string in a integer column in a DataGridView? The reason I'm asking is that I have a column wich displays the place for each runner (it's a sports application). And if the runner is disqualified, it will display "DSQ" instead of the place.
Now, if I want to sort by clicking the column header, there's a problem if there are more than 10 runners. If there are like 12 runners, the sorting will be like this:
