I have a requirement to allow users to browse directories on our file server, and allow the users to navigate to an excel file open it, potentially update it and save it. I have it working. I have 2 gridviews - the first binds to an array of DirectoryInfo and the second binds to an array of FileInfo. I render the name of the file as a link in the grid, like this:
a href='file:///<%# Eval("FullName") %>' target="_blank" >'<%# Eval("Name") %>'
When the link is clicked, the excel file is opened within a browser. In order to save, it seems they have to do 'save as...' and it's confusing. Here is where my questions are. What's the difference between opening an excel file within a browser, vs. opening it with excel? Can I have a link to the file in my grid as above, but cause it to open using the Excel application instead of the browser? Does it matter that the excel files are on a file server? I think my users would be more comfortable editing the file within Excel - not in the browser. How can I accomplish this?

View 8 Repliessave, edit and delete files in the data grid.
View 1 RepliesThe gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help

View 14 RepliesI have is my columns are separated by spaces but these spaces can vary between 1 space and 20 spaces. So would it be possible to replace all spaces with one space? This will mean that each column is seperated by one space and I can then start working on my next bit of coding with deleting columns.
View 30 RepliesI have two text files. The fields in each text file are separated by a space (" "). Some of the fields in column 1 of file 1 match the fields in column 1 of file 2. However the third column in file 2 is a numeric field. What I wish to do is check every field in file1 against the field in file 2, and if the number is 1 then remove the row from file 2, if the number is > 1, then subtract one from it.
I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
Dim values As New Dictionary(Of String, Integer)()

Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is
Dim line As String
Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line
I am trying to make the code edit the a line in a text file, but it ends up deleting all the text and add the line at the begging of the file.
Dim FILE_NAME As String = "config.conf"
Dim i As String

I found this code on here to open a text fille, do a find & replace then save the changes, and the code is in a loop that will do that to every file in a given folder. My question is I also have files in sub folders, and more sub folders, and i'm not sure how deep it goes. I want to recursivly go though all the sub folders and do this to all the files, not just the files directly in the main folder.
Here is the code so far:
Code:
FolderBrowserDialog1.Description = "Select Path for files to edit"
FolderBrowserDialog1.ShowDialog
OpenPathVariable = FolderBrowserDialog1.SelectedPath

I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.
How do i edit the column header of the GridView control on a web form? I have added a Table to DataSource as:
Me.gvSearchBrandList.DataSource = ds.Tables(0)
in here "gvSearchBrandList" GridView control But the GridView control display the column headers of the Table in the database. But how do i edit those column name in the GridView?
Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.
