Close An Unchanged Program Without Prompting To Save?
Apr 18, 2011
I have a form with textboxes for input. I have coded the Exit button to display a message box that asks the user if they want to save any data in the textboxes before exiting the program:
Private
Sub btnExit_Click(ByVal
sender As System.Object,
ByVal e
[code]....
The question I have if the textboxes are blank (nothing has been entered), how do I code the Exit button to close the program without displaying the message box asking the user to save the data.' Save the numbers. Call the btnSave_Click procedure.

I have a form with a listbox. I have controls on the form that can add items to the listbox with the click of a button. I already have the save file, open file dialogs working properly but I want to add something else that works with them. Lets say I open a file and the listbox adds all the strings from the file. Now, lets say I add something to the listbox and instead of saving the file, I just close the whole form. How do I make my program ask if i want to save the changes to the file when it is about to be closed? (I only want it to ask that IF there are changes to the file).

I have a datagridview bound to a datatable via a dataview. The user is allowed to edit cells in the datagridview, thereby editing cells in the datatable. I recently found that if the user editted a cell, then closed the form without ever clicking on a different cell (thereby causing the current cell to commit), the change was vanishing because the editted contents of the cell were not being saved back to the datatable.
This was only happening if the user closed the form. Clicking on any other control on the form also caused the cell changes to commit. After rooting abut in the DGV properties, it appeared that all I needed to do is add the following code to the Form Closing event handler:
If Me.dgvCurrentRedds.IsCurrentCellDirty Then
Me.dgvCurrentRedds.CommitEdit(DataGridViewDataErrorContexts.Commit)
End If
Sure enough, this caused the change to be registered in the underlying datatable. However, it was then getting obliterated by a different process, so I went looking for the source of that problem, and eventually tracked it down to this:
While the preceding code is causing the datatable to receive the new information, the datarow that has been changed still has the status Unchanged, even though it should have the status Modified since it actually has been modified. The fact that it appears unchanged causes some other code to obliterate the change, but that's irrelevant.
The question is, why is the row status UnChanged when it certainly has been Changed, and is there any sound way to force the row status to update?

I have 2 Forms.Form 1 is main and holds a button that should show msgbox with date that is selected on datetimepicker which is on Form 2. Date shown on msgbox should be in short format (dd.MM.yyyy.).On program start datetimepicker should be reset to today and msgbox should show today date unless user selects another date on Form2. If user goes to From 2 and changes date Form 2 should save new value and msgbox should show it after button click on form1. How do i do this?I made myDate parameter in settings of type "DATE" and i didn't set a value.on form1 load i have:my.Settings.myDate = Today on Form2 load i have: datetimepicker1.Value = my.Settings.myDate on Form2 closing i have: my.Settings.myDate = datetimepicker1.Value
This sets date on picker correctly, but when i go to form2 and change value, then close form2 and reopen it it still shows date that i have chosen, but msgbox shows initial value.

If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.

I need to have my application to prompt the user to see if he wants to save the settings or not before the application exits.I got this to work this way: I added an event handler to My.Application.Shutdown. This event handler does prompt the user and save the settings if the user answers "Yes".But in order to stop the application to save the settings anyway via its regular way, I have to set My.Application.SaveMySettingsOnExit to falseAs I said, it works, but it just look like a bad logic to set SaveMySettingsOnExit to false to have it to save the settings saved on exit with a prompt.
My question is: is there a way to get it work like this:
-SaveMySettingsOnExit =true -- PromptBeforeSave =True ( Save and Prompt)
-SaveMySettingsOnExit =true -- PromptBeforeSave =false ( Save and no Prompt)

I have an application that creates files at certain directories, deploys them and then removes them when neccessary. Under Windows Vista and 7, access for my program to carry out such commands are denied because UAC is blocking it.Now i am NOT using Visual Studio, i am using SharpDevelop and my project is a Windows Form. How can i prompt the user with the UAC dialogue so my application can acquire UAC elevation and carry out its tasks?I would also like to point out that everything works perfectly when UAC is either turned off or the user runs my program with Administrator Rights.

I've got my code to delete rows out of the database when the user clicks on the Delete button in my GridView, but the GridView isn't updating to reflect the new data changes.
Here's my code:
<asp:GridView runat="server" ID="grdQuestions" AutoGenerateColumns="false" Width="100%" CellSpacing="10"
PagerSettings-Visible="true">
<HeaderStyle CssClass="aspNetHeader" />
[code]....
EDIT 1:Did some stepping through the code and found that e.CommandArgument is not getting a value in grdQuestions_RowCommand
EDIT 1 (Revised):The fact that e.CommandArgument wasn't getting a value was my mistake. I'd changed the way it's value was being assigned without removing the previous method.The code runs through grdQuestions_RowCommand and then goes into grdQuestions_RowDeleting and then executes GetModuleData.I have a feeling that to view changes to the grid, a PostBack might be required, but I've removed all DataBinding to an If Not IsPostBack Then block because the alternative caused problems with the DropDownList whose selection is used as a reference to populate the grid (ddlModules selected the Module whose Questions will display in the grid).

I add a row to the DataSet using the following code:
Dim NewRow as DataRow
NewRow = gds.Tables("TitleDataSet").NewRow
NewRow("Title") = txtTitle.Text
NewRow("Local_number") = nubLocalnumber.Value
NewRow("Number_suffix") = txtNumberSuffix.Text
etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L
dgvTitle.AllowUserToAddrows = True
but that did not have any effect.
Solved. Was missing the final command:L
gds.Tables("TitleDataSet").Rows.Add(NewRow)

How can I assign a value to a message box for when the default value displayed in the text box is unchanged. ie. If my default value is 17 and the user clicks ok without retyping a number, the Input value displayed in a textbox will be 0.
Currently I have:
Public Class Form1
Dim MyValue As Double
Private Sub But_EnterInput_Click(sender As System.Object, e As System.EventArgs) Handles But_EnterInput.Click
MyValue = CDbl(InputBox("Input a value", "Data Input", "17", 200, 400))
[code]....
This works however if the user types 17, the textbox will read 0. not what i want.

I've got lots of textboxes bound to a Dataset. When I make changes to a textbox with the mouse/keyboard the rowstate becomes changed - and when I do the .EndEdit and update the row it goes to the DB.
I've got some textboxes that get changed in code. When this happens the rowstate remains UNCHANGED. Updates to the DB never occur.If the textbox is changed in code and I also change another textbox in the UI then both changes make it to the DB.
I've verified that the "in-code" changed field in the dataset is actually changed - but the ROWSTATE is still printing as UNCHANGED.Here I'm showing that field 29 has changed to "blank" - but the RowState still is UNCHANGED. Why would changes to the .Text property of a bound control does programatically not change the row state?
Seems a google for this does uncover issues like this - but nothing that's helped me fix it so far - here's one link I can't make sense of[URL]..

This is the first time that I will have ever actually published a program and I have a question about when it goes into 'real use' Right now I have string variables that sets the values of a few text boxes that can be edited and 'saved' (the variable values change to the new input).
When I publish the program will these values be saved in the variables after the program is closed then re-opened? Or is everything reset when the program is restarted? And if it is all reset, is there anything internal (aka not a xml file or something) that will hold the data and keep the changes?

I want to compare differences between two tables in my database with identical schemas.
vb.net
DataTable1.Merge(DataTable2)
Dim changedRows As DataTable = DataTable1.GetChanges
'changedRows is always Nothing. Why???
The DataTable1 is updated with rows from DataTable2 correctly. i.e. missing rows are added and datarows that don't match are updated. But the RowState of each row is still unchanged. I need to have the rowstate (added/modified/deleted) so that I can update the database table.
