If I replace an image in a picture box, should I dispose the original image first?
Or, what about this situation:
Dim bm As New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
Does bm need only to be disposed at the end, or should it be disposed before each re-creation?
A big oversight there on my part. I knew a control took care of disposing its children but It hadn't occurred to me that I should dispose an old image if I replaced it.
A) can i set the minimum width of a new created tab ?

View 2 RepliesThe file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

NOTE: There may be multiple instances of <firstName> within the file. 1000 xml files with all replacing names, address etc. with the same fixed name such as John Smith These will be used for testing and to prevent sensitive data from being leaked

I am making a program for work, i have it partly coded, unfortunately i don't have a wifi connection for my laptop right now which makes it hard to add my code here. What i am trying to do is have the user pull in a text file from anywhere on the computer using a open file box that pops up, i got that part, to make sure that is working i have a textbox that reads the data of that text file, it gets pulled in fine using a stream reader. Now what i need to do is search the text file for certain values, and depending on the selected item in the listbox which is on another form, change that value in the text file, im guessing i will need to use a stream writer, and ive seen examples used based on the file location(C:....) but in my case im not sure how to do it.
