Programmatically Created TextBox Retains Text Value After PostBack Even If Control Is Cleared?
Jan 21, 2011I have a drop down menu, and based on which item is selected, I call a web service and then dynamically create some text boxes.The first time I drop down the menu and select an item, it works perfectly, and the text boxes are created and populated dynamically. However, the next time I drop down the menu (after the first postback), and select something different..fter the second postback, the original values remain in the textboxes.

Forms :: Stop Loop With Button Control?
Dec 5, 2010I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.

View 1 RepliesList Getting Cleared Every Button Click Inside Update Panel?
Apr 22, 2010url...I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel.[code]Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again.I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked.
I've tried won't get it to work.It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback.The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associated Faculty list is getting reset each time I click the button?

View 6 RepliesStopping Multiple Timers - Stop Button To Stop Each Timer One At A Time
Feb 26, 2009Alright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

View 5 RepliesGet All My Textboxes In Tabcontrol Tabpage1 To Be Cleared Of Text Thru The For Each Loop
May 11, 2011Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

VS 2010 : Use A Stop Button To Stop A Loop?
Dec 7, 2009I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

Strategy To Override Enabled Property Of A User Control?
Aug 5, 2009I have a usercontrol with a picturebox and a few buttons related to it, such as LoadFromFile, Paste and Zoom (that last one pops up a new form). Is there a way to override the basic Enabled property of the usercontrol so that I can keep the Zoom button active all the time, while turning off the other buttons?
I realize there are 2 "obvious" replies. don't do Enabled=False, create a custom method. do everything in the one form, not a usercontrol, so you can pick and choose disabling. Both are less than ideal, given that I'm putting this control into a couple of existing forms, so I'd like to work around how those forms already behave. So is there a way to override the behavior of my usercontrol when it gets disabled? What would be my best strategy?

The problem occurs when a user click their 4 digit ID number and then click enter, the next user then comes up, types their 4 digit ID on the number pad and when they press enter it runs the code twice (this is due to the fact that the enter button has focus, meaning i intercept the enter, run my code, then the button runs that same code)

Uses A Start Button And Stop Button?
Feb 5, 2012I have been able to successfully place a stopwatch into the worksheets of a grading system I use for speeches. My difficulty is that the sotpwatch stops watching when I begin to keyboard comments or enter numbers that trigger the vlookup's created for general comments. Below is my code. My question, is there code that I need to add that will ensure the timer continues to time until I tell it to stop. The stopwatch I have uses a start button and stop button. Each instance is set for the sheet where it needs to keep time.
