I'm working with a connection to a Access db. I noticed that when the mdb file is not found in the location it should be, an exception OleDbException is thrown. I would like to create some kind of form where the user specify the new position of the Access mdb file to continue to work. Then, it would be useful to save the new location as well I suppose. But, where do I have to handle that exception?

View 4 RepliesI have a folder with a bunch of different files in it, and I want to display each file name on a line in a single textbox (or block, i don't care) so that the user knows what files are available to be read from. The name and number of files within the folder will change frequently, so making a .txt file with all of the file names wouldn't be an acceptable solution.

View 6 Replieshow to get different backcolors and how to change them using ListView.ItemCheck.
I am using ListView in a self written control (basically to improve padding). In some deployments, CheckBoxes is set to true and I use a RaiseEvent to return the Index of the row selected using an ListView_SelectedIndexChanged event.
In other deployments, I am using the control with the CheckBoxes set to false. But clicking on a row does not fire the ListView_SelectedIndexChanged event to be able to use RaiseEvent to return the Index of the row chosen. I have tried using a MouseUp event to capture the mouse Y coordinate. But conversion of that coordinate to an Index position is both inconsistent and inaccurate with my primative code of
return = (point.Y - me.top) / some constant
I have used ItemHeight on a ListBox in a similar situation but ListView does not have an ItemHeight property.
how I can capture the Index of a row clicked in a ListView without checkboxes?
I would like to know if there is a command to make a program choose between certain integers. For example, I would like my program to make a random choice between the numbers 12, 118,224 and 300.

View 9 RepliesI'm working on a browser, and I can't seem to get it to show the current URL in my textbox. I have tried this code:
Private Sub Form_Load()
WebBrowser1.GoHome()
Url.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).LocationURL
End Sub
But I keep getting the error "'LocationURL' is not a member of 'System.Windows.Forms.WebBrowser'"
I need it so that it changes according to tab. I think it might use the
CType(TabControl1.SelectedTab.Controls.Item(0), code but I'm not sure.

View 3 RepliesI have a VB.NET application with a connection to an SQL Server 2003. On the server there are two databases, MyDatabase and MyDatabase_Test. What I would like to do is to show a dialog when the program starts that let's the user choose which database to use. My idea is to create a new form as the starup form that sets this property and then launches the main form.Currently the connectionstring is specified in the application config file. Best would be if I can specify two different connection strings in that file to choose from, but for now it is also acceptable with other solutions like hardcoding the two connectionstrings into the startup form.EDIT: In the dataset.xsd file there seems to be the relevant part
<Connections>
<Connection AppSettingsObjectName="MySettings" AppSettingsPropertyName="MyDatabase_ConnectionString" ConnectionStringObject="" I

View 5 RepliesI have a program issue I am trying to work on. I have multiple comboboxes(12 total) on a form.I am attempting to update some settings from what ever the user selects from the combo boxes. I am trying to keep the code as small as possible, so I thought about having all the comboboxes have similar names only different by a number being changed at the end. (ex: cbo_1, cbo_2, cbo_3, etc...)And using a For next loop to advance through each combobox and update the settings as the for next loop advances.(This might be a stupid way of doing it, but its the first idea that came to mind.)
