WM Mousedown At Specific Coordinates

Oct 12, 2009

Another little problem.I have a form with a control (Picturebox or perhaps flash) which uses graphic hotspots instead of controls with handles so when the control receives a mouseclick, it does different things depending on the coordinates of the click.I can obtain the handle for the main control and can see where the hotspots are as they look like buttons and set a point to that location.How can I send a mouseclick (WM_Mousedown?) to the precise point on the control?If I'm not mistaken, using Sendmessage with BM_Click would tell the control it was clicked but without coordinates.I'm trying to do this using Visual Basic from Visual Studio 2008

MouseDown And Effect Based On Location Of Mousedown?

Jun 22, 2011

how to view and populate a listview with a text file. Now I come seeking wisdom on how do create an effect based upon the location where a mousedown event occured.

Here is my example. (I like to give simple examples because it helps me learn rather than be given the answer and learn nothing).

I am working in vb.net, in a windows form. I have a map of Western Europe called picturebox1.

I want another form to pop up when a user clicks on a section of picturebox1. For example: I want a "Germany" form to pop up when the user clicks on Germany. And such for if France, Spain, Italy, Austria, England, Scotland, etc...based on the location of the mousedown event.

Historically, when working with a picturebox with sections that were rectangle, I would do little screenshots and overlay them over the picturebox and use that as a cheat.

The challenge here is that the countries are polygons and now I need to learn this for real. I am looking for a little direction on where to go to learn about a mousedown event that causes an effect based upon the location of the mousedown event.

This can be a challenge because each country is of different x, y location coordinates so I image I need to create an elaborate if or case statement to capture and evalute. However, I don't know how to acquire the coordinates of a mousedown.

Set Coordinates For Each Beam At Intervals Of 610 Then Write That Coordinates System To A Text Based *.SCR File

Dec 2, 2010

I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

Detecting Shift Key On Mousedown?

Sep 5, 2011

In vb6 when you wanted to alter the effect of a mouse click, you could use the mouse down event and alternate the action depending on the value of the shift, control and alternate key. (and also detecting if the right or left mouse button was clicked)

When trying these in my project, I couldn't find the right codes to do this. I can't imagine this feature isn't available so I'm sure I am just messing up somehow.

Exception During MouseDown And DoDragDrop Not Propagated

Jun 16, 2011

During a MouseDown event, I issue a DoDragDrop. In the subsequent DragDrop event, I call a DLL to update a Ms-Access database. The SQL is in error so there is an exception. I can catch the exception in the DLL but not in the MouseDown event. Stangely without any try block, stepping over the ExecuteNonQuery() returns me to the line next to the DoDragDrop without the debugger stopping on the exception. In release mode, the exception is completely ignored. There are posts talking about event being "indirect" but I dont understand.

Capturing MouseDown/Up Through Child Controls In A Mobile .NET Application

Feb 27, 2009

I want to implement basic finger gestures within one of my apps, but have got stuck at the first hurdle. There are a few examples on the net, but they seem to use custom controls that do not allow easy use of other controls. I really just need a way to capture the MouseDown/Up methods even through a child control, still allowing clicks to be captured by whatever control has been clicked.

Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?

Make Object Follow Mouse On MouseDown And 'Stick' On MouseUp

Apr 14, 2011

I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.

How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.

IDE :: Getting The Screen Coordinates?

Apr 13, 2010

it is designed to be able to interact with foreground windows and display certain bits of information as each foreground window is displayed. The foreground window will most of the time NOT be a windows form so this makes things that bit more trickier for me. The program below doesn't produce any errors but the problem arises when I try and get the X, Y coordinates of the cursor, at the moment when ever the cursor is moved around I get a very long number as the X and nothing returned for my Y. I find I can set the X,Y coordinates to anywhere on the screen, can also get the foreground forms title,it's RECT coordinates but need to get the cursor info correctly.

Option Explicit On
Imports System.Text
Imports System.Runtime.InteropServices
