Using MS Access 2003 I am trying to build a command button in a form which clears the contents of a table column (which are tick boxes) - the idea behind it is this - the database is a contacts database for a club. Every year there is a subscription to be paid, so I want a column to annotate those who have paid (using a tick box). At the end of the year this will be reset - hence the reason for trying to produce a command button that clears out the ticks. What I using is this ....Private Sub Command11_Click()Dim strSQL As StringstrSQL = "UPDATE TBL-Master SET TBL-Master.campaign = '';"DoCmd.RunSQL strSQLEnd Sub(TBL-Master is the table name, campaign is the column name)What I am getting is a runtime error - 3144 -

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I am creating what could amount to quite a few temp files on a terminal server using the System.IO.Path.GetTempPath. My question is this. Can I trust Windows to clear that directory on a regular basis or do I need to clear it in code?

This week I am doing a simple addition, multiplication calculator and am having a little problem clearing data and resetting the enter button. It is supposed to keep the add and multiplication buttons disabled till the user has entered two numbers into the list box, then you are able to choose between addition and multiplication. What I am trying to accomplish is once I hit the clear button the enter button becomes available again to enter numbers into the list box again and do the whole thing again.

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.
I'm using an array to populate a datagrid. I want a password protected button to be able to clear the data from the grid. I thought this would be fairly easy but so far it's not working. The following code doesn't generate any errors but the array still has data in it.
If txtPassword.Text = "bucswin" Then Array.Clear(DataGridValues, 6, 23) frmMain.DG1.Refresh()
I currently have a chart that plots lines of a changing value every time it is called via a timer.
Everything is running as I expected and I am happy, but now I want to be able to press a [STOP] button which will stop the timer and stop the graph from updating, (which I have coded and is now working OK), BUT I then want the code under this [STOP] button to clear everything from the graph, so when I re-start the timer, the graph is cleared and starts plotting fresh points on a clean graph.
The problem I currently have is that when I press the [STOP] button and then press the [START] button, the new lines that get plotted are "added" to the existing lines that are already on the chart, instead of having a new "blank" chart, with no data on it.
So what I am really asking is does anyone know if it is possible to reset a chart clearing everything off it so it is ready to start displaying fresh data?
I was hoping it was something like: "Chart1.Clear" or something simple like that, but I can't seem to find anything that will do it.
bare with me here ok I posted on here a while back, like month to 2 months ago about creating an array of data (user inputed data). But was suggested to go the class route. After weeks of lengthly reading came up with a list collection class.
I have a timer that runs every time by itself, and for the code the runs in it I would like to have it clear the dataset before it does anything, the timer runs every 10 seconds, so I tried to do dataset.clear but it would crash if the dataset had no values
I have a button that inserts data into a database.With that button I want it to serve two functions.One for insert and one for clearing the textboxes after the insert is done.I did a little bit of digging around and her is a code snippet that i found online:
Dim ctrl As Control For Each ctrl In Me.Controls If TypeOf ctrl Is TextBox Then ctrl.Text = ""
After click the ok button all controls of displaying data should be clear in dataentry form. If i enter some data in the Combobox or Textbox for saving the data into the database, If i click the OK button all controls of displaying data should be clear, B`se i want to enter next record, so how can i do this?? Is there any Refresh Property is there?
