I have a DataGridView that is embedded in a TabPage of a TabControl and the TabControl is embedded in a SplitterPanel of a SplitContainer and the SplitContainer is embedded in a ToolStripContentPanel of a ToolStripContainer which is on a Form. I want to get the name of the form the DataGridView is on, how do I do this?
Note: Sometimes in my application the DataGridView will not be embedded in any control other than the Form. So I would need this code to work no matter what the DataGridView is embedded in. For example, if I send my DataGridView as an argument to a function how can I get the name of the form the DataGridView is located on?

I will have people send me (a zipped archive of) an entire VB project and when I try to open it, I get a message that "The system cannot find the file specified" for one or more files. I have had them bring their laptop with the project on it, and it runs, but when I search the folder, I only see the files they sent me. Apparently sometimes files get stored (or moved) elsewhere and their system will track the locations, so their computer can find the files??? Really not sure how or why this is happening.Is there any way to have VB report where all the files in a project are actually located? There are so many files and so many folders in even a simple VB.net project that trying to track these down myself is very frustrating.

I am unsure why all of the sudden i am getting this error every time i compile and run my VB.net program running Oracle 10g. It ran fine many times but all of the sudden keeps saying this now.
[URL]
It happens on this line:
myConnection = New OleDbConnection("Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(ADDRESS_LIST=" & _
"(ADDRESS=(PROTOCOL=TCP)(HOST=" & dbHost & ")(PORT=" & dbPort & ")))" & _
"(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=" & dbServiceName & ")));" & _
[Code].....
Once it gets to the myConnection.Open() is when it displays that error box. Like i said, i used to work just fine.

I always wondered, but is there a way to get My.Settings to save even when you move a program, such as copy it to another location? Maybe its just me but whenever I use My.Settings in an application, copying it into a different directory will reset all the settings, which kind of sucks.Is there anyway to get the values to stay in the application no matter what? If not My.Settings, than is there any way to store a value to a program so that you don't have to use external files, but so that it will remember the settings even when copied?

How to access a variable that is located in a private sub and then display that variable in another private sub located on the same form.
My actual code is:
Public Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim strFileName As String
strFileName = OpenFD.FileName
OpenFD.InitialDirectory = _
[Code] .....
Obviously, the sub in blue has nothing in it currently and so this is the one I would like to access the variable in. The variable I want to use again is 'FILE_NAME'.

I am new to VB. I have created some labels/textboxes in my Form1. I use them to do some calculations. Basically, this is my calculation area (in Form1) and then I want some of the results that have been calculated and showed in these texboxes to be shown in labels which are in another form (Form2). So here is what I have done in terms of coding:
Label12.Text = Transactions.ComboBox1.SelectedItem
Label13.Text = Transactions.ComboBox2.SelectedItem
Label14.Text = Transactions.ComboBox3.SelectedItem
Label15.Text = Transactions.TextBox1.Text
Label16.Text = Transactions.TextBox2.Text
These codes are in Form2 and Labels 12-16 are in my form2 as well. My form1 is called Transactions as you can see. Everything looks OK, when i run no errors, also when do the calculations and I go from form1(Transactions) to form2, labels 12-16 show the results from form1 but the problem when I go back to form1 and change the values and go back to form2, the labels 12-16 are not changed. They simply show the old values regarding of the fact that they have been changed in form1. So how can I make form2 to show them correctly, to refresh the form or what?

I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.

show me how to Load an Image that is located in a Folder created on a nother Form. Public Class CroppingForm Private Sub CroppingForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load PictureCropper.Picture = Image.FromFile(MainForm.CurrentFilePath, "PreView Photo.bmp")
End Sub The Image that is sepose to be loaded into PictureCropper is named "PreView Photo.bmp"
By using: PictureCropper.Picture = Image.FromFile(MainForm.NewImage)the Image is being loaded correctly.
Unfortunately this is going to be a problem later on, for a Image with a diferent name will allso have to be saved to the before mentiond Folder. That is the reson for var."CurrentFilePath" it mast hold te Folder Path only "D:DIY.ID Photos"
