Re: Multiple Default buttons on a form dependant on the situation

11-Jun-09 4:44

I have the following scenario. I have a WinForm that has a TableLayoutPanel in which each cell has a GroupBox that is logically separating the controls on the form. Now, each group box has a button which can be considered the default button if and only if Enter is pressed in one of the textboxes in that group box in that particular cell in the table layout panel.

Now, the default button is no longer an option and I assume that that is because of the table layout panel, so the idea of having one massive select statement figure out which "default" button to fire won't work.

Is there a proper way of doing this?

Are all the GroupBoxes identical? If so, then what about a custom control, derived from GroupBox, which has the controls already added. Perhaps adding a property to expose the Button and TextBox for flexibility. When the return key is pressed in the TextBox, use the PerformClick() method of the Button. Then, just add the derived GroupBox control to the TableLayoutPanel in place of the normal GroupBox setup

In what sense? Their contents represent different things, for example, Name in Arabic, Name in English, National ID Number etc. If you mean functionality wise, what is happening right now is that each Group Box has its own button that then grabs the info from the right text box and grabs all the information from the DB that matches that criteria. Some stuff are not unique (nationality for example) and so will return a number of matches.

I like the idea, but I don't know if its applicable in my case.

Thanks though Smile | :)

DefaultButton may not be available, but AcceptButton still is, because that's what it is called in C# WinForms! Big Grin | :-D

Nope. Its available on the form itself but not from any of the other controls (group boxes in particular), but I remember toying with it before I went to Lebanon and it didn't do what I wanted it to. Giving it another try..

Confirmed, the form is not capturing the Enter keypress. I'm guessing that the event is not bubbled up from the textbox.

The only reference to DefaultButton I could find on my local MSDN gave results in the System.Web.UI namespace.

By exposing the Button, TextBox and Label, you could make changes to them - with a bit of designer hodge-podge, and a few PropertyGrid attributes you might be able to get that code into the Designer.cs files, where it would normally be. If the controls are exposed, you can hook the events as usual. It would probably be immensely boring to add the controls manually, but IMO it'd look better than one humongous switch statement. You could also try putting the name of the Button which should be clicked in the Tag property of the TextBox and having a common KeyPress handler for every TextBox which reads the Tag, searches for a Button with that name in the Parent's Controls collection, and clicks it

Wouldn't that require a new control for each group box? It might be worth it in the future, but for now I'll stick to the multiple button solution.

Thanks buddy!

Yes, but the way I see it, you'd be creating a new control for each new GroupBox anyway. Unless you mean a new derived control, in which case no - you'd simply need to change the properties as usual

More of a philosphical question - why do you need multiple default buttons? The Accept button dismisses the dialog box, so how does it matter which button click causes it to go away?

Noone is going to just hand over the entire source code for such a large project.

It is not as easy as you think it is. You need intimiate knowledge of how Windows works, how the Shell works, plug-in support in your own application, writing and exposing an API that thes plugins would use to interface with your SideBar, ..., yada, yada, yada...

I’m trying to run the following command string from a GUI, everything works fine but I can minimize the command prompt or run it in hidden mode.

Any way to do this?

string stfamtv0001 = "/C" + ("\"\"C:\\Program Files\\ ThinTV\\PLINK.EXE\"" + " " + "appliance@%ThinConnectedFrom%" + " " + "-pw appliance" + " " + "\"killall -q vlc; export DISPLAY= Blush | :O

.0; vlc --video-on-top --key-vol-up 100 rtsp://stfamtv0001/streama\"\"");

private void data(string streamPath)
{
System.Diagnostics.Process ps;
ps = new System.Diagnostics.Process();
ps.EnableRaisingEvents = false;
System.Diagnostics.Process.Start("CMD.exe", streamPath);
ps.Close();
}

private void btnFOX_Click(object sender, EventArgs e)
{
data(stfamtv0001);

}

You can run it in silent mode.

ProcessStartInfo i = new ProcessStartInfo();
i.CreateNoWindow = true;
i.UseShellExecute = false;
i.RedirectStandardError = true;

i.FileName = "file to execute";
i.Arguments = (@"arguments");
System.Diagnostics.Process proc = Process.Start(i);

Can seem to get this to work, do you mind filling on the "file to execute" and the "arguments" so i have an example.

saurabh sahay11-Jun-09 5:58

If command to execute in shell is "FOP.exe -XML abc.xml - pdf abc.pdf"
Then file to execute is FOP.exe and arguments are -XML abc.xml - pdf abc.pdf
