Make Execution To Wait For A Mouse Event And Then Continue
Oct 13, 2010
I have code that just runs and runs, and I'd like it to stop and take a rest. I want execution to wait for a mouse event and then continue. I can't just put the code to be executed after the event directly into the Click handler, because many different sections of code need to stop and wait for the event. I'd like the code to stop, wait for the Click event, then continue. I tried the test code below, but it pretty much hangs the program during the Do Until loop; I can't even press Button2. [Code]
I am creating a small applicaiton for simulating dice roll. To simulate bounces I change the position of the picture randomly. Now to simulate more than one bounce, I used a for loop to continuously change the position of the picture box. But it is not happening as I planned, the form only displays the position of the last loop. I even tried using System.Threading.Thread.Sleep(1000) hoping to show the bounces, but even they show the last loop only.
For bounceCount As Integer = 1 To bounces bounce(pb_dice1) bounce(pb_dice2) System.Threading.Thread.Sleep(3000) 'I need to pause here and show the recent change in position then continue after 3 seconds Next
the bounce method changes the position of the PictureBox.
How can I pause my for loop, display the newly positioned dices, and then continue after 3 seconds?
how to avoid this error?"Insufficient memory to continue the execution of the program "i always got this error when i trying to execute or run my program.. it come to the point that time error will appear.
Is there any event for Right Mouse Click on Visual Basic?I wish to have a code or any thing so it allows a specific code to be done while Right Click while if Left Click another code will be done
I�m having trouble with my VS. It gives me the error "insufficient memory to continue the execution of the program". This is a dangerous error because I cannot save the project either. So all work is for nothing. Actually VS destroyed my mainform at one time due to this error.
Now there shouldn�t be anything wrong with the computer or the project. The computer is new and with ok performance. The program runs ok on other computers (up to 5 yrs old) both published and in debug. On the old computer I use VS express, on the new I have Pro.
I think it has something to do with the graphics (I have added one or two pictures to the project since testing it on the older computer). VS graphics really doesn�t work like it should.
I have a mainform (the one that got destroyed) which I want to use as a MDI container. I want to have a picture as background. That doesn�t work (!) so I use a picturebox instead. When showing childforms the idea is that som part should be transparent, thus showing the MDI�s background.
In debug, as well as after publishing, the result is the MDI shows, and it actually has the picture as background. However the childforms don�t show at all. They show up in the window toolstrip though. Needless to say I cannot save the project because of the memory issue.
So, am I right in assuming that VS cannot handle a simple .bmp picture, or what should I do to be able to continue developing?
I have a form in a vb.net windows form application called PolicyRefreshStatus.vb that has a ProgressBar control on it. From the main form called EditPolicy.vb I need to show PolicyRefreshStatus.vb over top of EditPolicy.vb - but the way things are wired I'm controlling the the ProgressBar and it's steps from logic inside EditPolicy.vbIf I display the PolicyRefreshStatus.vb bar using the .show() method things work fine.The problem is if the user clicks back on the main form then PolicyRefreshStatus.vb losses focus. If I show PolicyRefreshStatus.vb as a modal form using .ShowDialog() then execution halts in EditPolicy.vb after the .ShowDialog() statement.
so for example in the code: mPolicyRefreshStatus = New PolicyRefreshStatus mPolicyRefreshStatus.pbMax = mPolicy.ClaimsUpdateMax
I have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.
Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Interval = 60000 Timer1.Enabled = True
[CODE]...
Is it possible to force this event to occur instead of waiting for it?
First, I launch a website in Internet Explorer from VB.net and automatically login the user with ther username and password. As soon as the username and password fields are automated, I send "enter" to the website so it goes to the next website. This part works perfectly. However, my problem is that i want to send a mouse click event, which i have already written, to click a hyperlink on the next website page. I tried a few different things, none of which worked. My program is automatically logging in the user and doing the mouse click event at the same time. I have tried to use the "sleep" command, but the mouse click event is still not executing after the second webpage loads. I have tried using nesting "If, then" statements and that has not worked either. Does anyone know how to make sure the webpage fully loads before executing a sendkeys routine or a mouse click event? This is my code thus far:
If (Search.ComboBox1.Text = "IWR") Then BlockInput(True)'this disables the mouse and keyboard Dim IE As New Object
[code].....
There are no errors, everything is just executing all at once instead of letting the second webpage load and then executing the mouse click event.
I have an application that takes a long time processing information on a datagridview. So, I was thinking on a "please wait" dialog, with a progress bar in it.
Problem:
- I want it to behave like a ".showDialog" that prevents users to access the main form.
- But it shouldn't stop the code execution.
I tried to create a new thread to show the dialog, but this way it will not "lock" the main form... I want it to be always on top and focused, while open.
I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.
I have a slight issue on my program. I have everything in working order except for displaying "You Win!" or "Try Again!" after all text boxes have been hovered. Currently it displays the answer on the first hover because all boxes are already populated with random numbers from an Array and it knows the answer. I want the label to display at the end of the game on the last hover event.
Public Class Form1 'Declare variables we want to use on more than one sub or function. Private randObj As New Random(1) Private LottoArray(5) As Integer
I have set the controls mouse enter and mouse leave events. My problem is that the mouse leave event fires if I mouse over any of the child controls (like the name box for example).What I need is for the mouse leave event to fire when my mouse leaves the entire control, rather than firing when I mouse over any of the child controls. Here are the events as I have them so far:
Private Sub DeliveryControl_MouseEnter(sender As System.Object, e As System.EventArgs) Handles MyBase.MouseEnter Me.removeImage.Visible = True End Sub
how to pause the execution of code in an event handler.
For instance in a forms load event how can I have the rest of the programs features continue to run but wait 5 seconds before the code in the load event handler is executed?
I have a VB2005 application where the PC waits for data packages from a target. Part of the data package contains what to do next. I am using SerialPort1_DataReceived thread to pickup this data package and "looking" at and extracting the "next step" data from the package then go do it. The issue I have is I must exit the SerialPort1_DataReceived thread to do this and not do everything inside the SerialPort1_DataReceived interrupt routine. In C there is something like this:
I am try to make a character that follows the mouse, but I cannot find any way in vs 11 to get the mouse coordinates? It is a vb application, could someone please help me out? I tried pointer.location, pointer.margin, but still cannot do it.
I'm trying to write some code that stops and waits for an event then continues execution. I want execution to wait for a mouse event and then continue. I can't just put the code to be executed after the event directly into the Click handler, because many different sections of code need to stop and wait for the event.
I was thinking I could make a console application that would have a FileSystemWatcher - watching for a .BAT file being created in a folder - and when it sees that file it does a PROCESS.START on it.
I have this do while loop that I am having trouble with. I need to know how to make the loop continue to the next line after it has looped around once. So far I have it outputting like this.
$*$*$*$*$*$*$*$*
But what I really need it to do is output like this
How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.
I have an app that gets info from the internet into a label, the progam then decides which event will hapen depending on the info obtained, either load next form and continue or Application.Exit
My problem is that the speed that the info is returned from the net, varies and because the info is late sometimes the program exits when it should not.
In my vb program, I have two forms that work together to allow you to define an almost arbitrary amount of designs. In the first form, there is a two-dimensional array, storing an integer (not important) and an ID class that I defined as a public inner class in another form. Clicking on the "Define ID" button in this form will take you to the next form, where you will define a new ID or edit an old one based off of an index in the array you selected or entered in the first form's combo box, using multiple fields in the second form to define its different aspects.
What I want to happen is the first form's code to be suspended as the user defines the ID in the second form, then they click on the Continue button on the second form. After a bit of error-checking, the form either is momentarily hidden (which is how I originally implemented it) or returns the edited ID object, but only if the error-checking does not indicate any input is incorrect.
Originally, I simply grabbed the ID by using newForm.curID and set that to its spot in the array, waiting for the user to finish by using newForm.showDialog(), but sometimes the program would return a null exception because I don't think I copy the IDs correctly.Also, though the errors show up for a small amount of time, the Continue button saves the ID regardless of its correctness. Is there a way to manipulate the showDialog to get a result response out of it?
Short version: I need to either return an object of an inner class in one form to an array in a calling form or wait for a form to finish and use the calling form to copy its object, then close the callee form.First Form's "Define" button method
Private Sub DesignButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DesignButton.Click Me.totalCoilBox.Focus() 'calls validating method, makes textbox yellow if invalid' If totalCoilBox.BackColor = Color.White Then Dim newForm As New IVD_DesignData 'creates an object of ID called curID as well'
