DragOver Event Causes A Pause?
May 4, 2011
I have tried many different ways to make this work. Every attempt causes a pause where the drag operation is not recognizing the drop sites under it. There are many long narrow flowLayoutPanels that allowdrop of my button. I am basically wanting the scrollbar(vsFLP_UnitPanel) to scroll if the condition is met. It works, but for some reason there is a pause when the scroll begins.
Try
If e.Data.GetDataPresent("myButton") Then
Dim show As Integer
[Code]....

Does anyone know why a ListViews dragover event does not fire when dragging over a listview column header or an empty row?I'm trying to highlight the row a user is dragging over. Everything works with the exception that when I drag over the column header or an empty row the previous row stays highlighted since the dragover event doesnt fire. Is there another event that I should be looking at? I've checked the hover over and it doesnt fire either.

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 would like to highlight the item in a listview that the mouse is hovering over during a drag-drop operation. I'm using a similar method for treeview that works great, but for a listview I'm having trouble. I found a C# example online, but the VB.Net equivalent did not work, unless I translated incorrectly. Here is my
VB.NET
Private Sub AddonDirList_DragOver(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles AddonDirList.DragOver Dim hoveritem As ListViewItem = AddonDirList.GetItemAt(e.X, e.Y) hoveritem.Selected = True hoveritem.EnsureVisible() End Sub
When I use this code, not only does the highlight not work, but the drag-drop operation does not work at all. Rather than the typical drag-drop mouse pointer, the circle with diagonal line pointer is shown, which is what you would normally see if the listview did not have dropping enabled.

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 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.

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

I've been trying to figure out how to pause a process. It seems I need to use 2 different APIs: SuspendThread and OpenThread.I found some C# code at this link that was working for them.After I translated the code to VB, I get nothing when I run the code. I debugged the app and put a watch on the function.The following is what I got from the watch: Name 'SelectedItems' is not declared.[code]In order to work with the selected process, I'm parsing the Process ID. I then use that PID to get that process and then work with it.I sue this type of code often in my project and it works just fine, which is why I am confused that I'm getting that message from the watch.

My problem is that I have a textbox that is filled with a line of data from an attached barcode scanner. I want to make it so when something is scanned into this box, another function is triggered (it clears the textbox and commits the data to a CSV file, so the user can scan another barcode). I was using a .TextChanged function so that when the text was changed in this textbox, it would commit it then, however the problem with this approach is that if the serial number is 77G8DS, then it will commit 7,7,G,8,D and S individually, instead of an entire string.

I am having trouble with an Access form which runs some VB code behind it. The form accepts lots of user inputs and these are then grabbed by my VB code to calculate a result. This all works fine but does take some time for the calculation to complete due to the size of the datasets. Rather than the user having to stare at the same screen and wonder what is happening, I have another form which pops up to tell the user the calculations are in progress. The problem I am having is that this window will not display properly until after the calculation is completed. It seems as though Access cannot handle displayinging my window whilst the calculation is being caried out.
Is there any way to delay the calculation in VB so that my window will display correctly? The calculation can then take place after this. Here is my code:Private Sub Calc_Click()Dim ccombo(11) As IntegerDim Total As IntegerDoCmd.OpenForm "calcsinprog"
I would like some kind of delay or pause here to allow the window to open properly before the calculations below.
ccombo(2) = Me.c2combo.Column(1, Me.c2combo.ListIndex)ccombo(3) = Me.c2combo.Column(1, Me.c3combo.ListIndex)ccombo(4) = Me.c2combo.Column(1, Me.c4combo.ListIndex)ccombo(5) = Me.c2combo.Column(1, Me.c5combo.ListIndex)ccombo(6) = Me.c2combo.Column(1, Me.c6combo.ListIndex)ccombo(7) = Me.c2combo.Column(1, Me.c7combo.ListIndex)ccombo(8) = Me.c2combo.Column(1, Me.c8combo.ListIndex)ccombo(9) = Me.c2combo.Column(1, Me.c9combo.ListIndex)ccombo(10) = Me.c2combo.Column(1, Me.c10combo.ListIndex)ccombo(11) = Me.c2combo.Column(1, Me.c11combo.ListIndex)ccombo(1) = Get_PostCode_Score(Replace(Me.TextBox1, " ", ""))

When I run this code, it does not seem to open the OpenFileDiaplog diaplg box, or if it does, it closes it immediately, and I get at index out of bounds exception at the " infileStream = getFile.OpenFile()"This exact same code works without problem in another application I am building. So maybe its something about the IDE environment?I think, but am not certain, that this code worked in 2003 .net. I then used the VS wizard to automatically convert to the 2005 environment that I am now coding in.
Dim infileStream As Stream
Dim getFile As New OpenFileDialog
getFile.Filter = "All files (*.*)|*.*"

My application first checks if an SQL Server is installed before it runs. If there is no server it installs one. Now I want the application to pause or exit during the installation, since its thread may compromise the installation process, or is it not?. How do I do this? The Sleep() mmethod may not help because I can't know how long the installation process would take.

I want to insert a pause between the display of one control (a button) and the display of another control (a label) on a windows form. Specifically, I want the form to load with the button (and other controls) displayed, then, after a pause of two seconds, the label to display. I have tried timers, and .Sleep() but the effect is not what I want. That is, there is a pause before all of the controls are displayed, and all (including the label) are displayed at one time. I want most of the controls (all except the label) to display normally, then, after a two second pause, I want the label to display (on the same form).

On my main form i need to pop up a sub form and await user input before proceeding. I am able to pop the form but not able to pause code excecution until the user input is there. Here is what i have tried:
If chk_athor_cobb_scholi.Checked = True Then
Vselect.Visible = True
While Vselect.ex2 = False
[Code].....
The problem of course is that the while loop causes a crazy infinite loop and locks the program down during excecution. How do i await the user input?

I have a form that has a webbrowser and two buttons in it. [code] This all works great but when the last line is run in Button 2 [code] another page is displayed before the data I am trying to get is available. There are more fields and another button to be pressed. However, because another page is loaded, I don't think I can just plop in the lines of code I need to manipulate the website because of load delays. Should I use VB's timer to delay a few seconds before running the next sequence of code?
