Making application Vista compatible?

Can someone point me to some good material on designing an application to be Vista compatible? I've did a minor google search but haven't found anything of value.

Vista is a nightmare. The main thing tho, is to make sure you don't try to write to any files in the application directory. Your config files need to be in the users folder, not the app folder.

You can actually call an API called WindowFromPoint. So, hide your window, call that API on the screen point you clicked, convert to a point relative to the window and send it a WM_CLICK message. And a WM_LBUTTONDOWN and WM_LBUTTONUP. FIddly, more than anything.

Ya no luck with WindowFromPoint (in vista) so far... Also how do i "hide" a form from WindowFromPoint but keep it visible?, i tried making it not enabled, and some ShowWindowAsync(shades.Handle, SW_HIDE) which definatally hides it from view, but i want it visible still...

Also i tried with one of those lowlevel-ish hooks to watch the mouse when it's off my form, and so far WindowFromPoint returns 0 regardless...

something that caught my eye though was:

private const int WM_NCHITTEST = 0x0084;
private const int HTTRANSPARENT = (-1);

/// <summary>
/// Overrides the standard Window Procedure to ensure the
/// window is transparent to all mouse events.
/// </summary>
/// <param name="m">Windows message to process.</param>
protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_NCHITTEST)
    {
        m.Result = (IntPtr)HTTRANSPARENT;
    }
    else
    {
        base.WndProc(ref m);
    }
}

but it doesn't work for other threads... else it'd be very good solution :P

Ok been through hell with this, and starting to show progress:

1. i made a new WindowFromPoint function that effectively finds the window underneath. to do this i had to use api:enumWindows... whichs gives a list of windows in the correct z-order, and just filter the results to visible windows that don't match my programs handle... then just check which rectangle the mouse is within and there you go... it works 100%

2. sendmessage to relay messages is no joke as it would appear... pain in the ass would best describe it... apparently something is blocking any messages from getting through! my guess = vista lol.

i tried using microsof spy to watch for any messages in a test program, and i placed my window above it... and spy showed no messages getting through...

that's not to say "some" messages don't get through... i did notice doubleclicking on the taskmanager through my form did infact do what double clicking would do to it... but nothing in way of rightclick, or highlights... and the code that sends these messages is same... basically catch alot of mouse messages in my wndproc, and send them to another window... so i'm not sure what to do next.

i need another way to send mouse messages :P

ConnectionStrings from settings file.

Sunset Towers14-Jun-08 11:36

14-Jun-08 11:36

I have 2 connections strings in the settings file that are used by various datasetgridviews and other functions. The problem comes in that the databases are in the \CurrentUser\My Document\MyProgramsDataFolder. Other data is also being stored here for processing.

I know this may not be considered a "Best programming practice", but it suits the nature of the program.

Is there anyway of setting the connection sting in the settings file so that instead of

Data Source=.\SQLEXPRESS;AttachDbFilename="|DataDirectory|Database1.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True

it looks something like

Data Source=.\SQLEXPRESS;AttachDbFilename="|MyDocuments|Database1.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True

The |DataDirectory| value is a substitution string that indicates the path to the database so you don't have to hard-code the full path. There is no corresponding |MyDocuments| substition string.

What you should do is call the AppDomain.SetData[^] method. If you don't, the following rules are applied:

For applications that are put in a folder on the user's computer, the database folder uses the application folder.
For applications that are running under ClickOnce, the database folder uses the specific data folder that is created.

Trap Cancel Button Without Using MessageBox Class

Win32SF14-Jun-08 11:21

I have a file that opens automatically with an excelApp.Workbooks.Open statement, i.e., I'm not using MessageBox.Show. If the file is in use, I get the message, "'filename' is being modified. Open as read-only", with OK and Cancel as options. I need to trap the "Cancel" option so I can take various actions if the user chooses this. But since I didn't use the MessageBox, class, how do I do this?

I guess the obvious thing is, can you check afterwards if it opened or not ? If it didn't open, you can assume they pressed cancel ?

Christian: Sorry, I guess I didn't explain it very well. The Excel file being opened is in background and isn't launched by the user. However, if there's an Excel object left open from an exception being thrown during testing, then during the next program launch, I get prompted by Excel that the file is open and do I want to open a Read Only version. I'd like to be able to Cancel at that point but, if I do, I get a COM exception. So I'd like to trap the Cancel and redirect the code so I don't get an exception. But I don't know how to do that without using the DialogResult class.

Actually, it's very helpful. Pointing out to you that we have an ASP.NET forum ( which you still haven't found, I just answered this in the web dev forum ), means that

a - you don't clutter our forums with off topic questions, and
b - you ask in a place where people who can help you, will look.

Which just means you get an answer faster. Sorry if you don't think that will help you at all.
