01 Nov 2014, 16:58
Hi Dear:
I have Developed an cBot and want to load a winows Form as a specific perpouse, the code i used is here:
Rectangle workingArea = Screen.PrimaryScreen.WorkingArea;
Form fm = new Form();
fm.ClientSize = new Size(200, 200);
int left = workingArea.Width - fm.Width;
int top = workingArea.Height - fm.Height;
fm.Location = new Point(left, top);
fm.ShowInTaskbar = false;
fm.ShowIcon = false;
fm.MinimizeBox = false;
fm.MaximizeBox = false;
fm.FormBorderStyle = FormBorderStyle.FixedToolWindow;
fm.Text = "Test";
fm.Show();
every things is OK but the generated window is Hanging ! like picture below :

Might be do with the thread the form was created in.
I'll have a look when I get a bit of time.
Yep, it is created in the cTrader main thread and Show() isn't returning.
I have some developers notes somewhere from a Spotware developer on creating a new WPF Window. I'll see if I can dig them up somewhere.

I have looked for the notes, but it seems to be hidden somewhere in an old Archive.
I'll keep searching, but Perhaps I hope that the same person will repost here.

Got it!
CreateWindow method in this code from the MT4 to cAlgo library.
The dialog box that is available in MT4 can be replicated using an WPF window.
That code is how they did it.
I have adapted it in the past before for my use for an old Stochastic alert dashboard thing that I did which since has slipped out of usage. I will keep digging to find the code, but I think that above should suffice.
It can be found here fully:

Might be do with the thread the form was created in.
I'll have a look when I get a bit of time.
