I am a beginner to programing and have a project where I want to select a file for output. Currently I have it set up to mannually type in the path, what I need to know is how can I code a button to be able to navigate to a directory and provide a file name and pass that back to my input box? Thanks in advanced.

In the dialog meanu there should be an open file dialog. Add one of those to your form.

On your buttons click event, ( Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click), add this code (assuming name of open file dialog is openfiledialog1)

<br />
        Dim FilePath As String<br />
        Dim Input As String<br />
        OpenFileDialog1.ShowDialog()<br />
        FilePath = OpenFileDialog1.FileName<br />
        'Filenames means multi-select; to open more than one<br />
        Input = InputBox("Something", "Title", FilePath)<br />

You get to select the path from a dialog, and you use a string to pass it on to the input box, no error handling included.

Inputbox has optional sections, and default and title are included. So you can optionally add a default input.

NEED: .NET multi-table master-detail type...

NEED: .NET multi-table master-detail type customizable forms and datagrid generator or at least easy-to-follow idiot-proof instruction. ASPMaker.net ain't got it. ASPRunner.net ain't got it. Those tools are great for quick easy creation of add, display, edit, copy, delete, search database connectivity and functionality but for only one table!! I need to do all these quickly using data from three Oracle database tables (will also need to consider furture use for MS Access tables). Any intelligent leads appreciated. My database is small with only about two dozen total fields and only two master-detail relationships - not that big of a deal, it would seem. But my search has turned up nothing usable so far. Grateful for any and all good ideas. Programmers, freelancers, all responders/responses welcome. I just need to get it done in a hurry!!!

Thanks all!!

A Better ComboBox

Can anyone suggest a good third party combobox? The combobox needs to be able to do the following:

Automatically fills the text at the cursor with the value of its dropdown values list. As characters are typed, the ComboBox finds the closest matching item from the list and automatically fills in the remaining characters. Appended characters are highlighted so that they are replaced by any further typing.

Any help would be appreciated.

it is an owner-drawn control, which means that you'll have to drawn yourself the control, define its behavior, etc...
moreover, i doubt that Visual Studio were made with VB...

You need to create an ImageList object. Add images to this and then pass its reference to your ListView. You can create a large (typically 32x32) and small (typically 16x16) ImageLists and assign them both if you want. It'll use the large ImageList for the Icon view and the small one for the Details/Report view. You can also just use one ImageList for both large and small if you want, and the images won't change size in the list.

lstDSNode_Fill.LargeImageList = myLargeImageList<br />
lstDSNode_Fill.SmallImageList = mySmallImageList

You can then assign an image to your ListViewItem by giving it an image index.
mItem.ImageIndex = 0 'Assigned 1st image in list.

One more thing. The following bit of code that you had is inefficient. There is no point in calling AddRange() if you're always only going to add 1 item. Plus you're allocating an array here every time.
.Items.AddRange(New ListViewItem() {mItem})

I suggest that you change it to the following.
.Items.Add(mItem)

Hi from Sydney

Anyone know if you can declare a "local static variables" value to a Public variable and preserve the Public variables contents after exiting the private sub?

I hope this sounds right? Thanks... Cool | :cool:

Inside Outlook (not Outlook Express!), and all the Office applications for that matter, the language is Visual Basic for Applications (VBA), not VBScript. The two languages are closely related, but there are differences between them.

If you wanted to run an external application, you'd have to have the Windows Scripting Host do it for you. In your VBA Code Editor, go to Tools, the References (I think!), and set a reference to "Windows Script Host Object Model". The you can write code like this to get an external app to run:

Dim ws As New WshShell
ws.Run("notepad", 7, True)

Hi!

I'm writing a program that uses a drawlines method to plot a series of xy point in a PointF Array. I have checked the points in the array and they are all fone, but as soon as I try to plot, the X coordinate gives an overflow error. {PointFArray.X = 1.#INF}. What could be the problem?

Any help or advice would be much appreciated!

Thanks
