Detect Textbox Change?
May 7, 2012The Textbox_TextChanged event fires when a key is pressed or when text is pasted while cursor is in a text box.
Is there an event that fires on Textbox1.text="NewText"? How do I detect this?My reason for doing this is I would like to reformat text property automatically on assignment rather than do something like textbox.text=myreformat("Newtext").I can put code in validating or validated event but then I'd have to force focus/lostfocus to trigger one of those events.

Aug 21, 2010I'm trying to figure out some simple code to detect when a single pixel changes color at a location I choose -anywhere- on the screen (ex. 100,100). Maybe with just a msgbox popup when it changes.

I should be able program the rest of the program around it, I just need the detection part. That is where I am stumped.

VS 2010 Detect Text Change?
Jun 16, 2011I'm creating a basic text editing program that will be used for UCAS Personal Statements (probably not a unique idea but hey). It will be a basic text editor with no special text formatting to sit in line with the guidelines of UCAS (there is a character limit for personal statements).
What I want to do is have a save/load option (which is easy enough), however on the "Exit" function I want the program to detect text changes and alert the user that saving is recommended (ya know like when you close word and it asks if you want to save blah blah blah)

VS 2010 - How To Detect Field Level Data Change
Sep 26, 2011I have a question about event handling. Is it possible to detect field level data change in vb.net? i don't want my codes to be dependent on the the bound control's event to detect the change on the field value. I'm thinking there must be a better way (coming from a Delphi background). For example: a change on the Qty field will automatically trigger the event to compute the invoice detail Amount - (pseudo-case sample: Amount = Qty * UnitPrice).
In Delphi, every field is treated as an object with its own properties and events. So it's very easy to associate an event with it.
Example:
procedure TfrmInvoice.qryInvDetQtyChange(Sender: TField);
begin
inherited;
qryInvDetAmount.value := qryInvDetQty.AsInteger * qryInvDetUnitPrice.AsCurrency;
end;
How can I achieve the same using vb.net?

View 7 RepliesDetect Mouse In User Control - Border Color Change?
Dec 28, 2010I've got a couple of instances of a user control on a flowlayoutpanel. The user control has got a couple of controls on it, and very little / almost none of the control's original space is visible. I need to know when the mouse is inside the usercontrol. What then happens is that the border color changes (of a control in the user control), and when it leaves the control, it changes back to original state.
I tried the following:
Private Sub ctrDashboardWidgetFrame_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.MouseEnter
Try
ShowControls()
Catch ex As Exception
[Code] .....
And it works, but it only works when you move over the original visible space of the user control, and doesn't work when you move over the child controls inside the user control. How I'll be able to achieve this to also work while the user is inside the full user control and not just it's visible space?

Program To Detect Change In Selected Pixel On Screen - Memory Leak
Mar 21, 2011I am fairly new to visual basic and have written this program to detect a change in a selected pixel on the screen. When the pixel changes, a sound plays every x seconds. It works fine but after a few hours of operation a possible memory leak causes it to either crash the program or the PC. I have watched the process and I can see 4k added to it every 4 seconds or so. Where this memory leak is coming from?
Here is the code:
Public Class Main
Public pointx As Long
Public pointy As Long
Public areaselected As Integer
Public TimeToPause, SecondTimer, changefound As Integer

May 6, 2011I often use VBA to automate internet explorer and interact with web sites.I can find links on regular URLs I navigate to, fill in forms on them, etc.But I don't know what these types of windows are that come up or how to get a hold of them to click links on them or enter text in their forms if there is any. It comes up then grays out the screen it came from. It looks like its some java popup or something. I'm not interested in the site this is from, its just an example of one to show what I mean. I've been searching and looking but can't figure it out.
View 5 Replies.net - Form.Bounds With 2 Screens?
Feb 11, 2011I have 2 screens, and 2 forms. I want each form to fill a screen, so I did the following code:
s = Screen.AllScreens
f1.Bounds = s(0).Bounds
f2.Bounds = s(1).Bounds
(s(0) is my primary screen, and s(1) is above it.) F1 fills s(0), but f2 does not fill s(1). The size of f2 is set correctly but the location is set to (50, 0) instead of (0, -1024). Maybe location won't accept negative numbers? If so, how can I get my form to the other screen?

Communications :: Programming LED Screens Using .NET?
Nov 24, 2010for a test project that i'm doing i am looking for ways to program a LED screen. I ordered a few LED screens (320x160) that can be connected together). Using a special controlcard the whole thing can then display text etc. Using the software that a Chinese supplier gave me. All the above works fine. But I am depending on the software I have. I have VB.Net experience and I would like to put the software aside and write my own software. I would like to set up the COM connection and tell what LED to activate.
Problem i'm facing is that the chinese cannot provide me good use of the software dll files. I need a small Vb.net program that does the above. Would somebody be able to figure out how to do this.
How To Programmatically Disconnect Screens
Nov 21, 2011I have a PC with four LCD monitors attached, but often I leave it unattended and need only one monitor running. I've set up power strips so that I can flip one switch on a power strip to turn on or off the other three monitors. The problem is, when I turn off the other three monitors, the computer makes the disconnect sound every few seconds. you can go into Control Panel->Display->Change display settings, and under 'Multiple displays' disconnect the monitors you are not using, and them reconnect them when you need them again. However, this is time consuming to do manually.can I program this in VB .Net, i.e. is there a Class or some registry keys that I can use to connect or disconnect monitors the same way as through the Control Panel?
