I think I'm still not clear to You. "There is no clicking and so I don't think I can use OnMouseClick".
And I think I need this:
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.mouseclick.aspx
And
http://msdn.microsoft.com/en-us/library/system.windows.forms.control.click.aspx

Anyway it's freaking me out!How difficult it could be to perform a simple right click at current cursor location??! Forget everything just write a simple C# program which when run performs a right click!Like have a "for" loop from 1-10 and for each even value of i(checked after a delay) do a right click.

I know I'm very bad at programming.But that's how learning begins.

Can you please give sample code snippet for that^^
I found this for Control.InvokeOnClick:http://msdn.microsoft.com/en-us/library/system.windows.forms.control.invokeonclick.aspx
protected void InvokeOnClick(
Control toInvoke,
EventArgs e
)

And toInvoke type list is long:http://msdn.microsoft.com/en-us/library/system.windows.forms.control.aspx
I need to know which one to use.

What do you need for a trigger of this check?
->A slightly constant value of this variable over a small duration of time.
A time or an addressing of this variable?
->Both.I think.
why? What's the ultimate purpose of this technique?
->Please read the comments of you answer(--SA) on this thread:http://www.codeproject.com/Questions/209985/How-to-manually-set-mouse-events

I've been through this page a number of times, but problem remains same->the user has to perform a mouse/keyboard event in this example.My user is using "onscreen keyboard" and no mouse at all! Please read my above comment.
Something like this:http://cameramouse.org/

Thanks!

Sorry for my "small" summary.

Actually, I'm making an iMouse(eye mouse) where user uses my hardware setup(a headmount camera) to interact with computer.The user is a limbic disable(no hands) and can't use the normal mouse. My application software is to be used like a driver(not actually a driver) which detects headmount camera and allows the user to interact with computer by tracking his/her eyeball movements and blinking.

What I should have made clear is that user is "not clicking". He/She is just blinking the eye(s) and my app has to detect the blink and perform the clicking at current cursor location.The blink to perform a click is slightly longer than normal blink.

So, there are no mouse event from user side(as is the case with all available code samples) and so I can't use "OnClick" type events handlers :(

I can detect blink and all I need is to trigger the click!

Moreover I'm a Student and not a professional and so I'm not dragging myself into std GUI practices. I only need to give a demo(in fact, final presentation) that it is possible to click using blink.

Thanks for your help --SA!

Well,I'm not skilled enough to create ".dll" and so not in a mood to implement "Global Mouse Hook".

To know what exactly I'm trying to do you may just look at headings of my previous posts:http://www.codeproject.com/script/Answers/MemberPosts.aspx?tab=questions&mid=7063045 which were ofcourse answered by you only(--SA)!

But,I'll give a small summary.

I've a loop that keeps generating X and Y value dynamically using image processing(OpenCV) by detecting the Iris of the user.
Next I need to move cursor in sync with the Iris movement and I'm passing the pupil-coordinates as corsorpostion. I've somehow finished that.

Next I need to detect blinking to perform mouse clicks(lefteye blink=left click like that) and there are no good methods available for that.So,I'm tweaking the pupildetection procedure.When the user blinks, the pupil-coordinates remain fixed to its previous value, if it remains fixed for few seconds that means user is trying to click...for normal blink rate has to be considered. That is moment when I've to trigger the clicking at current cursor location.

I got less that 24hrs to finish that^...so I've to trick it!!

I thik this explains my problem.

AmarjeetAlien 12-Jun-11 14:20pm View

That only Codeproject knows!! I saw that later.Basically I hit uparrow+enter :)

AmarjeetAlien 22-May-11 2:57am View

Thanks for for detailed explanation!
CvPoint is a strudture
typedef struct CvPoint
{
int x;
int y;
}
CvPoint;

I'll try the modifications. Sorry for that bad naming convention.

I read that its a copy paste form here:http://stackoverflow.com/questions/1315266/displaying-another-app-in-my-form[^]

But anyway thanks for the reply.

Well,I found the documentation for "user32.dll" here:http://www.andreavb.com/API_USER32.html ..not all APIs ....and code snippets are in VB6!

Making list of APIs I need and will ask another question on how to deal with them.
Thanks!

Actually I'm developing an eyemouse for disabled peoples(http://img192.imageshack.us/i/cap1e.png/[^] http://img807.imageshack.us/i/imouse3.png/[^])

So I'm trying to port all mouse properties and functions to my application.I googled a lot and finally found I need to inport "user32.dll"....thanks Code Project that I got the solution.But so far I've been able to implement only "SwapMouseButton" using:

Collapse

[DllImport("user32.dll")]
public static extern Int32 SwapMouseButton(Int32 bSwap);

And
Collapse

private void Apply_Click(object sender, EventArgs e)
{
SwapMouseButton(Convert.ToInt32(BtnChkBoxBC.Checked));
ApplyDisable();
}

There are >700 API calls for user32.dll and I don't know which and all and how to call for mouse only. If you know some site which maintains such database with code snippet(ya,I'm poor at programming),please let me know.

Thanks SA!

AmarjeetAlien 1-May-11 16:47pm View

Thanks SA! for guiding in exact direction...reading P/Invoke tutorial(http://msdn.microsoft.com/en-us/library/aa446536.aspx).If you know other better link,please do post.

Thanks!

Thanks a lot Kim!
It worked happily.

AmarjeetAlien 30-Apr-11 9:29am View

Yes....but on double click.

AmarjeetAlien 29-Apr-11 6:57am View

one last question...are all mouse properties present in user32.dll only or I'll have to Import some other dll also.
Please Respond.
Thanks!

Thanks it worked fine:
private void BtnChkBoxBC_CheckedChanged(object sender, EventArgs e)
{
if (!BtnChkBoxBC.Checked)
{
SwapMouseButton(0);
}
else
{
SwapMouseButton(1);
}
ApplyEnable();

}

Thanks a lot!
Can you please let me know the name of other mouse setting...like "pointer speed","click lock",etc....in fact I'm implementing all mouse properties in my App.

AmarjeetAlien 27-Apr-11 19:27pm View

ApplyEnable() is for enabling "Apply" button(I hope the image link is working,let me know) which is desabled by default....I even don't have any code for "Apply" button action.
private void ApplyEnable()
{
Apply.Enabled = true;
}

AmarjeetAlien 27-Apr-11 19:20pm View

Thanks for the reply....but it didn't work :(
To let You know...I haven't added any mouse handler in my program....I've only created the check box which when selected should invert(in this case) mouse selection....this is how I used your code:
[DllImport("user32.dll")]
public static extern Int32 SwapMouseButton(Int32 bSwap);

private void BtnChkBoxBC_CheckedChanged(object sender, EventArgs e)
{
SwapMouseButton(1);
SwapMouseButton(0);
ApplyEnable();

}
