Good evening folks,
I'm building a simple application (A) that sends Strings to a textbox of another application (B). I was able to this step, but afterwards I'd like to automatically press a button placed just under the textbox. The problem is that I can't get the Handle of the Button; using "Window Detective"(similiar to Spy++), I see only the textboxes (called "TEdit", see the attachments) and no Buttons!. I'd like to add also that there's no only a Button but 3!! So, how could I press a specific Button? Is there another chance to get the Handle?

Based on the class name TEdit that's a VCL application probably coded in Delphi. The buttons are likely TSpeedButton and non-windowed. You won't be able to send them messages and they are not automatable.
Faced with this your best hope of success is to fake input. Fake the mouse click at the appropriate location on the form. It's not pretty but there's little option.

For the last 2 month I've written application in C# in Visual Studio. Now i have to port that application to Linux by Monodevelop. Well, I already solved most of the porting errors, but there is one that i cant figure out. All double click and mouse double click events from Visual Studio stopped working - I even created small 1-form application that i ported to Mono with only form and one event (double click) - it also didnt work - so that means Monodevelop cant port double click events from Visual Studio ? I already checked WND_Proc function and Linux dont throw up any corresponding double-click event (it was 515 for in window and 3 hundred something on title bar...). Im already giving up and preparing for writing additional code to fix all double-click issue in my code but maybe someone has an answer.
Im using Ubuntu linux (if its neccesary i might tommorow check kernel version), MONO: 2.8.3, Visual Studio 2008 and project in .NET 3.5.
When implementing mouse clicks, there are two main differences between Windows and Gtk# that you should keep in mind:
Gtk# does not offer a 'double-click' signals ('Events' in Windows lingo), but only single 'click' signals. However Gdk library does implements both double-click and triple-click with its EventButton class!
Gtk# differentiates between Widgets (or 'Controls' in Windows lingo) and 'Containers' (there is no direct comparable in Windows). Most widgets placed on a Gtk# form will NOT receive mouse click events. In order to receive a mouse event you need to place the widget inside a specific container - like EventBox.
Here is how you do it Gtk#:
A. Add an EventBox containter to your form (in the example below: eventbox1). You can place it behind other Widgets or since it is not visible, unless you specifically select it to be (or change its background color). You can put a widget inside the EventBox, but you are limited to only one widget, that will also get the shape and size of the EventBox.
B. Add to this EventBox the signal 'ButtonPressEvent' out of the "Common Widget Signals" (in the example below: OnEventbox1ButtonPressEvent)
Every time a mouse button (left, middle or center or a combination) is clicked inside the EventBox, it will trigger this event and the function OnEventbox1ButtonPressEvent() will be called. If you need to identify the button that was clicked while handling this event, use the uint value in: args.Event.Button typically '1' will be the left mouse button, '2' the center button and '3' the right button ('2' might be also when both left and right buttons are clicked).
By the way, mouse motion events (without a button press) are not sent by default. So if you need to sense them you will need to add the PointMotionMask as well in the first like of the code example below.
Here is a code example of the ButtonPress Event Handler (the EventBox name is 'eventbox1') catching a double-click event using the EventButton class:
// The following line is may not be needed but is here to show how to do it
eventbox1.GdkWindow.Events = eventbox1.GdkWindow.Events | Gdk.EventMask.ButtonPressMask;
protected void OnEventbox1ButtonPressEvent (object o, ButtonPressEventArgs args)
{
if( ((Gdk.EventButton)args.Event).Type == Gdk.EventType.TwoButtonPress)
System.Media.SystemSounds.Beep.Play (); // Play a sound only if this is a double-click event
}
The order of the events received (in case of a double click) is:
Gdk.EventType.ButtonPress
Gdk.EventType.ButtonRelease
Gdk.EventType.ButtonPress
Gdk.EventType.TwoButtonPress
Gdk.EventType.ButtonRelease
Hope that helps!
GTK# treats double-click events differently than Windows Forms. You're going to have to write code to translate the events. If you're doing that, you may as well spend the time arguing against double-click as an idiom.
I'm trying to write a program with C# that sends text into other windows.
How do I write a command in C# that sends a text into the window that is currently under the users focus?
For example:
If the user clicks an open notepad window, or an open outlook letter, or an open excel sheet, and then clicks the button on my program, a text will be "pasted" directly into the last notepad window/outlook letter/excel cell that the user clicked on last.
I hope my question is clear enough. I'm not so experienced and am missing a lot of terminology.
Take your application out of focus by minimizing or hiding the main window, and then send your text with
SendKeys.SendWait("Hello World!");
Finally, restore your main window.
If the code is executed in the main form, you could do this
this.Visible = false;
SendKeys.SendWait("Hello World!");
this.Visible = true;
Olivier's response actually seems more accurate (and taught me something :)) than my original "does not seem achievable". If you need an example, then take a look at this:
http://www.codeproject.com/Articles/18366/Sending-Keystrokes-to-another-Application-in-C
However, on a more complex level, without an API to call into, there is not much more that you can do beyond this solution.
Edit for those who say to use tab control
I would love to use a tab control; yet i have no idea how to go about linking the tab control up from the main form. I would assume that I would have to do something like this:
Create Form with a blank TabControl on it, no pages created.
Create a CustomuserControl (Add -> user Control), with my controls on it.
When a new chat comes in, create a tab control Item, Tab Control Page, add the Custom Control to the Tab Control Page. Add the tab control handle to the hash table, so that when new messages come in, they can be referenced in the proper control.
But, i am so not sure how to do this. For example, I know that I can create custom events inside of the User Control, so that, for example, if each control has a 'bold' button, i can each page that has that control on it, to actually USE the button.
Yet i also need to register message callbacks, so that I can use a MessageGrabber to send data to it, and tha'ts not assigned inside of the UserControl, that's assigned programatically when a new window comes in; but since I have no controls to reference, i can't assign.
KISS Philosophy
Wouldn't it be easier to just create the form, like i do now, and then just dock that form within a window or something? So that, in essence, it's still creating the form, but it's also a separate window?
Original Question
Okay, so i'm stumped (which isn't that big of a surprise when it comes to complex C# logic lol)! What i'm trying to do is the following:
Goal: Setup tabbed chatting for new chat application.
Completed: Open new window whenever a chat message is received, or a user requests a new chat from the roster. This is working perfectly, and opens only a window when the user doesn't already have the chat open. Nice and happy there.
Problem: I dont want windows. Well, i do want A window, but, i do not want tons of separate windows. For example, our Customer Service team may have about 10 active IM windows going at one time, i do not want them to have to have 10 windows tiled there lol. I'd rather they have a single Private IM window, and all 10 tabs docked within the window.
Logic: This is my logic here, which may be flawed, i do apologize:
OnMessage: Open new chat window if one doesn't already exist; if one exists, open it as a tab within the current chat window.
SendMessage: ^^ ditto ^^
Code Examples:
if (!Util.ChatForms.ContainsKey(msg.From.Bare))
{
RosterNode rn = rosterControl1.GetRosterItem(msg.From);
string nick = msg.From.Bare;
if (rn != null)
nick = rn.Text;
frmChat f = new frmChat(msg.From, xmpp, nick);
f.Show();
f.IncomingMessage(msg);
return;
}
Note on above: The Util. function just keeps tracks of what windows are opened inside of a hashtable, that way, when messages come in, they route to the proper window. That is added with the:
Util.ChatForms.Add(m_Jid.Bare.ToLower(), this);
Command in the frmChat() form.

Problem:
How can i convert this code to open inside of tabs, instead of windows? Can someone please give me some ideas, and help with that. I just can't seem to wrap my head around that concept.
Use TabControl
I am trying to make a WPF program in VS express C# I have multiple pages/windows.
I have my main page with a nice picture and a button that says 'Start'.
I want this start button to connect to my contents page/window its called 'modules'.
For simplicity (haha) I am also using blend. I get the point of setting the on click event handler in blend then swapping over to VS. but what do I write in the gap to actually get the button to go to the module window/page. I have been reading up in my spare time and still cannot find a simple answer for an absolute beginner. I can find many samples on how to get a button to display " Hi WPF" or whatever using a text box but thats obvisously not what I want.
i want to click the button and the start page/window to change to the 'module' window/page in the exact same way as blend sketch flow changes pages, in sketch flow you can just make the button navigate to the page you want. and that's all i want to do here page1> to > page2 'module'
i want to build a simple program which help you selecting pictures.
if you have lot of picture and you want to choose some of them then you see them 1 by 1 and when you see a picture you would lik to save on other folder on your pcyou just press a button ,lets say f5 and the program copy the phtot from the path you looking at to the destiny folder.
for that program i need to ask how to know if someone pressed f5 out of the form area and how to know in which path the user looking at.(i want to build it for myself atm so if its help i look with microsoft office picture manager)
about the clicking i search a little and get something named global clicking and hooks which i dont understand so much and about identify the path i have no idea .
tyvm for help:)
I'm not sure I follow the rest -- but if you want to capture the keypress event, simply add an event handler for KeyPress and determine if the pressed key is equal to the F5 button by using the Keys constants.
Here is a project on Code Project that does exactly what you need :)
http://www.codeproject.com/KB/cs/globalhook.aspx
The key press event wont work with the following (Link):
TAB
INSERT
DELETE
HOME
END
PAGE UP
PAGE DOWN
F1-F2
ALT
Arrow keys
Note: I think there is a typo on the page and the F1-F2 really should be F1-F12.
When you decide the key for your on key press event for the form area you are talking about it will look like this:
private void Form_KeyPress(object sender, KeyPressEventArgs e)
{
if(e.KeyChar == [keypressvalue])
{
//do your copy logic
}
}
[keypressvalue] will be the code for F5 if you choose to use this. I have found a mix of values for this (i could not get my test keypress event to pick up the F5 event, hence my note above) so i recommend running the event once with a brake point, inspecting the code, then brake and update your code, then test your logic.
Like the rest i'm not really sure what you want your custom logic to do.
Clairifcation: I'm trying to understand your question, so what you want is: When in Microsoft Picture Manager when you press F5 you want the image that is currently being viewed to be moved to a particular directory? Now if you are writing your own picture viewer and move software then i think we can help if it is the above i'm not really sure you can do that.
