I have a project where I need to call\execute a sub only after a certain timer has finished running and is disabled\stopped. The sub is called directly after the line of code that activates\starts the timer and the timer needs to run\tick for a couple of times before finally stopping itself with the help of a counter that's within the timer.tick event. The reason I need to wait for the timer is because it is working on some value that is needed by my sub.
Here's a portion of my rather long code that isn't working
'Assume this is my calling sub Private sub CallingSub(Byval value As Integer) Select Case value
[Code].....
But this method and a few others are not working and are mostly resulting in a non-terminating loop. What I don't understand is why is this happening and what is the proper way to wait for timers to finish. The timers interval is 30 milliseconds.
I am using a WebBrowser control in VB.NET and calling the Print() method. I am printing out using a PDF printer and when Print() is called it is not immediately kicked off (it waits until it has completed running code for the entire Sub or block.
I need to make sure the file I am printing too is complete and continue process with this file, therefore, I would like to print on demand and get some status of when the operation is complete. I have tried usign printDocument and process without luck.
I am running macros from a button click in my application. I want the macros to run sucessfully before it start another process. I want the StartMacrosI to start and complete first before it starts DeleteFilesI. I need to wait for it to complete before I do the next function/sub.
Below is my code. Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click StartMacrosI() DeleteFilesI() End Sub [Code] .....
I have the form put together but I have no idea what to next. [URL]This is a link that shows what the application is suppose to do if it works correctly [URL] There is an attached file that has what I have so far.
I have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer) Dim sw As New Stopwatch sw.Start() Do While sw.ElapsedMilliseconds < interval ' Allows UI to remain responsive Application.DoEvents() Loop sw.Stop() End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.
I'm developing a big VB.Net Winforms application. Every now and again, processing or db connections take some time and therefore I'd like a wait cursor (hourglass) to appear sometimes. I know I can do it like in this thread (in case someone needs the code):Hourglass?- technical discussion - developer Fusion - ASP.NET, C# Programming, VB.NET, .NET Framework, Java and Visual Basic Tutorials However, I have LOTS of code and I don't know when the user will need to wait. So, what I'd really want is to tell my ApplicationEvents file or the like to globally intercept after say 0.3 seconds and turn the arrow (default cursor) into the hourglass and at the same time disable mouse clicks and the like.
Making a simple form that is to step through a program iteratively. How can I get it to run a method each time a user clicks a button and wait once it is finished for the next click?
I have auto complete functionality in combo box ,it works properly but there is little issue ,I made the suggestion list appear for the text length more than 3 chars ,but the list appears after the length of 4 char (when user enters the fifth char of the text) which means when the code executed in the first time the list doesn't appear here is the code in Text_Changed Event
Private Sub TxtItem_TextChanged(sender As System.Object, e As System.EventArgs) Handles TxtItem.TextChanged If Trim(TxtItem.Text) <> "" And Trim(TxtItem.Text).Length > 3 Then 'Autocomplete
[code].....
Note : This issue causes the application exit (sometimes) on Windows XP, but Doesn't affect on Windows 7
Is there anyway to complete a progress bar just by going ProgressBar1.Value = 100 when you want it to finish. I have a button which starts a countdown, I need the progress bar to complete when countdown reaches 0. Ive already used the step version, but when I want to alert the length of the countdown, the progress bar finishes too late or too early.
I have a textbox that is filled using autocomplete. The autocomplete is a globally accessible sub that I use for textboxes and (I guess) comboboxes.My problem is that the autocomplete sub takes several seconds to fill the textbox. Is there some way my code could be improved? (The code below takes three seconds to fill for 288 autocomplete entries, which I don't think should be a lot for this kind of functionality.)
My best bet is that the autosorcecollection has to redraw itself every time an entry is added, and that causes the delay, but I'm not sure.Apart from taking time I think this global function is really handy, so feel free to use!
I am trying to fetch some specific data from a file which is updated frequently. So, i am trying to make my form wait till i get a particular data. i am using Threading.Thread.Sleep(10000)to wait and again check the data.
but form is getting hanged (showing NOT RESPONDING)
I am trying to get a form button to load the yahoo login webpage, wait until the send button was loaded and auto enter the username and password and hit the send button. My code is as follows
Public Class WebLogin Dim ie As Object Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click ie = CreateObject("internetexplorer.application")
My Startup form open very slow. How can I show a wait screen while Initialize Component. Then close this wait screen and show my Form. You can see my attached image.
I designed a application on vb.net 2005. Some of the forms in this application has databindings controls. Now when such forms loads it takes some time. I want a splash screen containg "Please wait" message to appear till the form loads and the wait splash screen would be shown for every several forms in the application not only before the start up form.
I'd like to make a simple program where my form consists of a textbox and a button. Here's the ide in a nutshell:in form1_load I invoke the sub:
private Sub LoopingLesson() dim i as integer=1 while true
[code]....
what I want is when i hits certain value, like let's just say i is divisible by 365, then the 'while' looping will stop, and a message box saying "target reached" appear. then after I click button1, the looping will resume until it reaches the next number divisible by 365, and so on.
While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.
1:50:657: ============================= ENTER WebBrowser1_DocumentCompleted EVENT ======================================== 31:50:657: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^THE NEW WEBBROWSER STATEMENT
I am using Process.Start in my application, which is working great.My only problem is, the program it "starts", is an installer, which takes about 5 minutes to install. I woud really like to hide all my forms and only show one that says "please wait", but i cant seem to get it to stay there till the process has finished.
I am now developing an app to manage process in my company. Since the app will mostly do heavy process such as :
1. Qerying a large database 2. Calculating data displayed on grid 3. Editing value on each cell in a grid and many more
When the app do these stuff, the screen would go into 'not responding" mode, which is quite suck.I am thinking to show a small form contain of 1 label (please wait...) and 1 picture (animated provess gif), but when I do this, the "please wait" form also go to not responding mode.
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
In C# if you start a snippet you press Tab to cycle through the snippet elements, and press Enter to complete and exit the snippet.
In VB.NET you still use Tab to cycle through the snippet elements, but how do you end the snippet? Enter doesn't work and I can't figure out the correct keyboard shortcut
ok I have a program that controls another program.. but sometimes the other program is not running.. so I ask the question "do you want to run it up" so if they it takes like 15 seconds to come up.. so really I dont want to do much on my program while we wait for that other program to finally come up..
normally when my program comes up I make sure the other app is running.. and it would come up before you would click on something to try to call it.. but during the day.. maybe their app crashes.. so then right before I try to make a call to it I will check if its running.. so I want to run it up but kinda put a hold on my code while it waits..
so whats the best way to do this ? stop my code.. call a timer and when it see's its up call again ?? or can I put in some wait in the code then continue... just looking for the best method people have used..
Im trying to edit an item in a listview. I can edit the item ok but i want to execute code to rename the directory after the edit. The code executes before the edit is completed? Is there a way to wait until the name has been change first? [code]
So I was reading a bit on AutoComplete of textboxes in VB.NET, but I can't really understand where these are stored? Is it a fully built in feature, or do I have to write some code for it to work? I've found the AutoCompleteMode and AutoCompleteSource properties of textboxes.But I want to append whatever I've written in the textbox to the autocomplete source. Do I connect the source to My.Settings or something
