Working With Text Files And Listview?
Feb 20, 2009I want to be able to grab a specific file from a specified directory, read the lines and display them in a text box. What I want to do, is search for multiple text files in a specified directory, display each name in a Listview and, as I click on them, their info is displayed in the text box below.
what I have so far:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Also, when I closed the program and re opened it, it duplicated all of the text files in the list, but did not duplicate them in the directory. Not that I want it to, it just seems odd.
Manipulate Picture Files (jpg, Gif, Png, Etc) In Visual Basic?
Jan 16, 2012For instance, I would like to read the picture's dimensions (width, height) and modify them to fit space available on a page. I have many pictures, so don't want to do this by hand.
If this involves using components or objects, where to find useful documentation about properties, methods, or whatever I need in order to write a program.
I'm using Vis Basic 2010 Express in Vista Ultimate.
*.txt Filter Not Working Properly?
Mar 14, 2011In my word processor I have an 'Open' option on a menu strip. Here is the code for it:
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
With ofdFile
.Title = "Select a file to open"[code]....
For some reason when I press the 'Open' item and open the ofdFile dialog box .txt files do not appear even when I have the 'Text Files' filter selected However, when I use the 'All Files' filter they appear. And the 'HTML Files filter is also working properly.Why are the .txt files not appearing when I use the Text Files filter?
.NET 2.0 .settings Not Working Properly?
Oct 18, 2011I don't even know where to begin describing this. I have a project, that uses settings, for some paths, settings that I retrieve with the My.Settings. function.In my laptop, when I change the .exe.config file, the settings are updated accordingly, but when I try that on the production server, it just shows the default value used while compiling.
I tried changing the solution configurations to debug and other custom configs with no effect.Tried to use the same folder copied and pasted without version control, still the same result.Tried a co-workers laptop, by using the last svn revision, it works there too. But on neither of the servers works.

Checkbox In Datagridview Not Working Properly?
Aug 16, 2010I have an unbound checkbox in my datagrid view along with other bound fields from a dataset. I do not need to send back the checkbox status to my dataset or the DB. Instead I will loop though the DGV and look for those checked and do another process with them after its done being loaded. The problem is this. When I check a checkbox, then check another, the first one goes back to unchecked and so forth, back and forth. There is no add, update or deletes needed for this DGV.

View 4 RepliesDatagridview :: Saving Changes Not Working Properly?
Jan 25, 2010i have a windows forms app which displays a bunch of records from my sql database. when i modify records in the grid and click on save, all changes are saved EXCEPT the changes made to the currently highlighted row. they aren't written out the database until i exit the actual program, despite clicking on my save button.so for example, if i change 5 different records in the grid, and click on save, and then click on refresh to reload the data from the database, 4 out of the 5 are saved correctly, but the row that is currently highlighted (meaning, the last row i changed) still has the old data.My code for the save button look like:

Jun 3, 2010If you try to access a password protected page it does a security check and redirects you if you are not logged in, retaining the URL (ie. Members/MemberLogin.aspx?oc=/PodCast/Default.aspx)The vb script places the "/PodCast/Default.aspx" in a variable and holds it until the login process is complete.Once the user types in their username and password it is suppose to do a Response.Redirect(strRedirectURL) and go to the "/PodCast/Default.aspx" but instead it goes to the default.aspx page for logging in successfully
