I have a current program that I have developed using visual basic and it does everything I want, however, I would like to "experiment" with the code and add other things to it but I don't want to mess up the code by working on my original project. How do I copy the project so I have it safe and have one I can "play" with.

View 1 RepliesI want to capture the original value and the new value from a cell in the DataGridView control. When leaving the row, I tried:
dgDataEntry.EndEdit()
Dim row As DataRow
row = tbl2.Rows(e.RowIndex)
Dim m_orig, m_curr As Decimal
m_orig = row.Item("amount", DataRowVersion.Original)
m_curr = row.Item("amount", DataRowVersion.Current)
And the values were the same. How can I capture the different values?
I made a copy of a VB application project, to make a copy of it for testing.
But when I debug the test copy while the orginal is still running (debugging from Visual Studio), focus changes to the original's main form, and the test copy does not run.
If I try to single step the test copy, same thing, focus changes to original, and test copy does not even step.
I have a WPF form that takes a list of objects that have locations and sizes and plots them on the canvas. I'm currently trying to implement an undo button that will throw out all the changes that have been made to the positions of the objects and revert back to the original collection that was retrieved when the form loaded.
As it stands now I go out to the database on the load of the form and get all the objects that will need to be displayed then assign the list that is returned to two seperate collections. The problem that comes up is that the two collections are actually pointers to the original collection and whenever one is changed the changes are reflected in the second collection.
Is it possible to copy a list of objects so that changes made to one collection won't affect the secondary collection?
So far I've tried simply using the assignment operator, passing the source collection into a function byval and scrolling through each element of the list manually adding it to the second collection and using linq to get all the objects from the original list and pushing the results to a separate temporary list and assigning the second collection to the temporary list.
I feel like I'm overcomplicating the issue but almost all the places I've come across while googling say that this behavior is by design, which I understand but it seems like this would be a fairly common idea.

View 1 RepliesIs there anyway you can send information back to the original creator of the program? Here is a quick example- I made a little program that gives you general information about your computer, when you click a button it sets the text box to specific information. One of the text boxes gives you the Version of your OS. I would like to know if there is a way to send the information in that text box back to me when someone clicks it and they are connected to the internet. FYI I would tell the person who clicks it before so that I am not stealing information, plus what is there to steal from a simple program I made.

View 3 RepliesBeen taking a programming class in school for the last year and we haven't really done anything with a progress bar so I was curious to see what I can do with it. I found some basic code to see how it worked and I get it.[code]However, instead of having a fixed time, I want the maximum to represent the time it takes for something to be done whether it be loading a new form, searching for something, etc. I don't know if that made sense, but basically I want the progress bar to react accordingly to the time it takes to do something.For example, in this little test project I just want the progress bar to represent the time it takes to load form2. I believe you'd have to change the maximum. However, I don't know how to get Form2's load time to be able to put it in the progress bar's maximum.

It doesn't allow me to resize anything or more the panel
View 1 RepliesI am using vb.net 2003 and an Access database connected via Jet 4.0 OleDb. I have identified the location of my database using a relative path with [code]My program was working fine and I began making some cosmetic changes.I thought it would be a nice touch to add a PictureBox on the first form and allow the user to select the image that he would like to see when running the program.I added a menu item to "change the picture" and on a form added an OpenFile Dialog. I added code to capture the location of the selected file and used it to identify the image to be shown.I included a table in my database to store the file name and path which is loaded when the program starts.This all worked fine. I could change from picture to picture and the image would be updated each time in the picture box and in the database. I could access the database and perform all of the functions of the program.
That is as long as the image files that I selected were located in program startup directory. If I selected an image with the openfile dialog which was located else where then I could no longer contect to the database. I receive an "unhandled exceptions error". Below is the openfle code:[code]Can anyone help me with the proper way to get set up the open file dialog so that the results do not conflict with my database connection, or re-establish the connection?[code]

Very simply, I'm positioning a small ListBox over a DataGridView column when the user right-clicks and selects "Show Distinct Values". This works fine until the vertical scrollbar of the DataGridView is clicked. Once that's done the listbox pops up all the way over to the left edge of the DataGridView. As confirmation of the problem I created a small app to test with.

Can I get an english explanation of .*? I kinda know what it does, but a breakdown would be nice on the logic behind it. Also, in the same manner, I'm after the specification for special characters, especially " but if it's doable, for as many special characters, or all of em as long as " is included.
EDIT: Might as well include the entire context, because I'll prolly be asking this in another thread in 15 minutes.

View 18 RepliesI am trying to create a program in Visual Basic which will measure the performance of the CPU with every core, one at a time. In this program, I decided to place a couple of text boxes that display the processor speed and the actual processor speed. I need to get the actual processor speed to update and I have tried doing this already using a timer set to tick every second. However, when I load the program it runs really slowly and prevents me form doing anything within the program, including trying to close it down, and all it does is updates the text box every second. I have looked in task manager to find out how much CPU the program is using and it shows that my program is using 0 - 3% CPU.

Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
