Way To Pause A Part Of Script For A Couple Of Seconds And Then Letting It Run Again?
Dec 26, 2011
i've been searching for a way to delay a part of my program to let another part load, all i have found is threading sleep and one way which uses huge amounts of processing power. does anyone know a simple way to pause a part of script for a couple of seconds and then letting it run again? ( the problem is i need to get values from core temp, i also need to open it in the program. at the moment it say's "Object reference not set to an instance of an object." because it hasn't loaded by the time it is tried to be accessed. )
I`m trying to figure out how to use a timer to do something for a couple of seconds. Let`s say i want to prompt a message for 5 sec and after to disappear it.Or On a button`s click to appear an image and after 3 sec to disappear it. How i`m i going to do it?
My application (MDI if that matters) has what appears to be a very quick jump/shift/jerk (lots of descriptions of it) in the first minute that the application is running. I have tried double buffering all the forms...
i have a for loop that is executing. i want while the loop is executing to be able to define using a variable how many seconds the For loop needs to pause before next iteration.
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?
I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:
see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
shutdown -s t 60shuts down the PC in 1 minute. I would like to make the seconds part of the syntax variable as:Dim varSec as integer Process.start(shutdown s t & varSec)But it doesnt work nor produces errors. Can it be done this way?
I am importing data from CSV file into a dataset using OLEDB data adaptor.I created a query with query builder to extract the desired data then copied the text generated into my code. Everything works as it should exepct that the seconds part of a datetime column is missing when the code is run.The odd thing about this is that the seconds part appears when i execute the query in query builder.[code]
1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.
I am using VB.net within Visual Studio 2008. I currently have GridControl where one of the columns fetches a real number from the database. Whenever I try to remove the value I get a red 'X' saying that the input string is not the right format even though I know it can display null because the row underneath fetched a null value for that column.
I am using VB2008 on Win XP SP3 and an relatively new using this language. I would like orientation or advice on how to proceed given the following:I execute an SQL statement, such as select * from MyTable where FieldX='aaa'An exception happens. Now I need to attempt to determine what went wrong:1. Cable was cut2. Syntax error in SQL3. PC where SQL Server is running crashed4. Timed outI need to attempt to recover from this issue. I have basically 2 options: It is a glitch that self corrects after a period of time, so I can just go ahead and retry the operation a few times. Option 2: It is something permanent, so no matter how many times I retry, the error will persist.
I want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.
I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.
I am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.
Is it possible to have radio buttion 1 control this code and have radio button 2 control the same code with different sizes? If this can be done it will get me buy until I learn a better way. It is a small envelope app, someday I will add a database to it too hold all my address. Right now I only use a couple different sizes.
dim a as integer = 1 dim b as integer = 2 dim c as integer = 3 dim result as integer
result = random ( a , b , c)
How do i write the random stuff in visual basic.and how would i write something that Deletes the a from the random ( ); so im only left with random ( b , c ).
I have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.
I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:
1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.
2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.
I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.
I have a filesystemwatcher that watches a couple of folders! The files coming to the watched folder are coming from a server. And for some reason the created event is not raised..If i move the files for a sec from the watched folder to a another folder and then copy them back to the watched folder it all works fine! Strange.So if the created event is raised from the same computer that the service is installed on it works great, but not if the files are coming from another computer.
1) Does this code make text the selected items text? If it doesnt then how would I do that?Dim text As String text = ListBox1.SelectedItem.ToString()
2)How would I make it so that if in combobox.items there is an item with the same text as the listbox selecteditem it is removed? This is what I have and it doesnt work.
If ComboBox3.Items.Item(text) Then ComboBox3.Items.Remove(text) End If
Very new to web development and had some session issues a couple of days ago. I have those now resolved but having trouble telling the page to redirect home after the session expires.
Using the example from my previous post:[URL].. I have this set in areas of my main page in order to redirect if the session has ended.
If Session("UserClassInstance") Is Nothing Then Response.Redirect("Login.aspx")End If During the testing; after Session_End fires, I go to the control that contains the above statement but seems to think that the session not nothing and will not redirect.
