i have added 3 .png files [done.png, failed.png, busy.png] to my project & changed them to "embedded resource" [from this wht i understand is that they will be integrated within the exe hence eliminating the dependency on the actual location it is stored]
i have 1 picturebox on my form whose image i have to change as per the output of something else
this is wht my code looks like :
If text1.text = "Done" then
picturebox1.image = my.resources.done.png
end if
[Code].....
but it gives me error during run time.. am i using the right code ? or is there an alternate method for this ?

I'm trying to read multiple values from a registry subkey in the CurrentUser key. I need to display these values in a listbox with multiple lines. I so far can only get one of the values from the subkey.

I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my

Currently, my application will send the contents of a directory into a list box.

folderDlg.ShowNewFolderButton = True

ListBox1.Text = folderDlg.SelectedPath

For now, all that is inside the directory is a text file. I would like my program to read the contents of the text file and remove a set of common words, but I don't really know how to move forward here. Would it be best to create a class that holds a set of words that I would like to remove, then loop through the text file, remove any words that match those inside my class and then write what's left to a new .txt file?

The problem there is always a blank line in the txt file at the end and so generates a blank list item. How can I remove this blank list item from the listbox? Is it best to try to remove the blank line from the txt file first or the empty list item from the listbox after the file has been read?

I'm a little new to VB, and I'm in a class for it, but I'm trying to do something we aren't going to learn in the class (mostly out of sheer interest) and I need help. I'm trying to read lines from a text file into a listbox, each line representing a new item on the listbox. For example, if the text file reads: [code]I want to be able to take that as is and read it into a listbox, where those words would appear in the exact same fashion; as a list, each as separate items. I've looked at the Help stuff and learned (sorta) about delimiters... but the thing is I don't want to write my entire list in a continuous line separated by commas--I want it to keep reading each line, and moving on to the next, until there are no more lines left. I am thoroughly stumped, and would appreciate it SO much if someone could help. For a frame of reference, this is the point I'm at now with my code: [code]Note that when I run the program, all it will do is read the first line of text available and stop; once I press ENTER in a text file, it decides to stop reading.
View 2 RepliesIf I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
