I use the "NodeMouseClick" event to activate my sub function when I select a single node. But the event occurs also when I click on the "plus" simbol NEAR the node, to open it.Is it possible to activate the event only when I click on a node and not when I open it?I hope to have well explained my problem.

View 2 RepliesI am creating a web browser in VB 2010. I have a search box, and I want to make it so that when I press enter in the text box, it searches. [code] The problem with this is that when I press enter, there is this annoying "beep". I don't know where this comes from. The only thing I can think of doing is making the event activate the search button, but I don't know how to do that either. How can I fix this?

I'm trying to make my application become the active window if it currently isn't as soon as the mouse enters the main form of the application (so there is no need to click the title bar of form itself to make the window the currently active one if it's not).
It only sorta/kinda work .... I have to enter the form with the mouse 3-4-5-6-maybe 7 times ... then the window finally becomes the active one.
I know the MouseEnter event is firing each time the mouse enters the app, but the main window isn't becoming active most of the time.
Private Sub frmMain_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter

I am attempting to create a timer that will activate a tick event every 1 second until stopped by an "If" statement. The tick event should then drive a clock measuring time in units of hours, minutes and seconds. The if statements handle the time readout, timer stop and activate another form after a set number of hours have elapsed. I have tried several different methods and while my application is running, it does not add increments to the integers representing the time units, refresh the displayed time units, or perform any of the timer related functions. I assume the cause is that I just don't know as much as I think I do (which isn't much)
Here is the applicable code:
Imports Microsoft.VisualBasic.ApplicationServices
Imports System.IO
Public Class SessionManager

Because event leave calls another sub i need the last active control. I have the textbox name txtTime{0} but obviously string is not a control.
So Two questions:
1) can a string value be attached to an existing control if i know it's name? Dim attControl as Control = newTime
2) All this could be avoided in event leave if i could get the left controls name. I have tried sender. tostring etc but nothing returns the textboxs name

I'm attempting to write a deployment tool using the TreeView. I followed a couple of tutorials I found online for populating the treeview with folders/subfolders/and files. That all works and my functionality for processing my file deployment seems to be ok, but I'm having a display issue.
My treeView displays my folder structure and the files inside each folder properly, even attaching the correct icon image to each folder / file.
If I click the + to expand or collapse a node (folder) everything is still fine, but if I perform a single click on a folder, it appears the _NodeMouseClick event is firing and not refreshing my contents correctly. Any subfolders are no longer displayed, and the files now have the folder icon. If I collapse and re-expand the folder node, everything goes back the way it should.[code]...
The error it has is that when one of the text boxes is changed the code changes all of them triggering every single function to activate. Is there a simpler solution other then recoding it from the start? also each different Private Sub is identical basically.

I know the code is very brute forced & sloppy but its the only way i really know how to do it.
I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

I have a vb.net application which does some processing. This processing can take a while. The application doesn't respond until the processing has ended and then it handle all events (such as click on buttons) that the user has done during the processing. I'd like to add a "Stop" button so that the user can stop the processing at some point. How can I do that? Could threading the processing (which is done in a function of the application) be a possible solution?
I tried to add a button which change a boolean value and putting the code of the processing function inside a while statement based on that boolean value. However it doesn't work because the click event on the button is processed only after the end of the processing.
I have a list of buttons in VB2010.What is the best way to assign a function to their click event.So every button has the same function, e.g.:
On Button Click
FireFunction(1)
End On Button Click
Without having to add a click event for every button.The goal is to produce something similar to what is done with the Control Array idea in Visual Basic 2006.
I have a system that has a gridview on one page with an Update Panel. On selection of one row of a gridview the system posts-back using that CommandName and CommandArgument to post the row that is selected, and then set a Session variable as the ID of that posted selected row. The other controls run Async correctly and the button in question is already registered using this on the RowDataBound event.
Dim gvRowSelect As GridViewRow = e.Row
Dim imbSelect As ImageButton = DirectCast(gvRowSelect.FindControl("imbSelect"), ImageButton)
ScriptManager.GetCurrent(Page).RegisterPostBackControl(imbSelect)
I would like to try and get this session on the button command and somehow within the master page, set a label to the current Session. On the imbSelect command the code is:
Dim cellSnapshot As TableCell = gvSnapshots.Rows(e.CommandArgument).Cells(0)
Session("Snapshot") = cellSnapshot.Text
Within the masterpage is there anyway of calling a function after the Page_Load, and after it has resolved all Postback events?
This is my code on button event click function
Dim con As New Koneksi

txtJumlah.Text)

I have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind. Each of the divs must pass it's own ID to the function. I can't use web methods as the function needs to identify which div was clicked and then show/hide/populate other controls on the page.

I think I have a timing issue. On the trigger of an event I call a function to update a value:
Private Sub t0_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles t0.Click
Input.ppProperty = "blank"
UpdateRecord("Hey", Input.ppProperty)
MsgBox(Input.ppProperty)
End Sub

Notice the difference, the property does not update until the function is completely finished.
Why?

I created a function that retrieves information on which checkboxes are checked. It returns an array which the information coupled to the checking of those checkboxes. Those checkboxes and the matching textboxes are dynamically created at runtime in that same function. I'm pausing the application to wait for a button to be pressed. I'm trying to find a way to use btnDone.Click event directly because the code always reloops my function once more recreating the controls.

Is it possible to use events like this? If not is there a cleaner way for pausing the application to wait for a button click (one that doesn't run the entire function again)?
