4.0 VS2010 Using VB: Force Textbox Update To Appear To Users Before Following Command Lines Are Finished (Onclick)?
Jan 14, 2012
I'm fairly new to ASP.net development.th something I have been spinning my wheels on. I would like to update the value a textbox and then load some data when a user clicks a button. I have this working perfectly but unfortunately the textbox change isn't visible until AFTER the data loads. I've tried several methods, updatepanel, backgroundworker, and async

I have some difficulties concerning threading [code]
Code:
1- Dim str As String
2- Dim x As New myClass
3- str = x.doSomething()
4- x.closeSomething()
I've included line numbers so I can just refer the lines by their numbers. My problem is, when the program executes, line 4 seems to be executed earlier than I want it to. It gets executed while ThreadX is still running in line 3. How can I force the program to wait until ThreadX has finished executing, before it executes line 4?

When I originally set up my project I 'hard-coded' my username and password in so that I could access a remote DB2 database. Now that I need to publish it to other users they need to be prompted for their own usernames and passwords. I've gone to "My Project/Settings" and deleted the items from the string - but when I run I get the following message on the statement:
Me.BATCHTableAdapter.Fill(Me.DB1DataSet.BATCH)
ERROR [08001] [IBM] SQL30082N Security processing failed with reason "3" ("PASSWORD MISSING"). SQLSTATE=08001
The settings are as follows (before I delete the userid and password):
Name:DB1ConnectionString
Type:(Connection string)
Scope:Application
Value:Database=DB1;Server=99.999.999.99:446;userid=myuser;password=mypassword;Persist Security Info=True;
The question is what do I have to do to make it forget my userid and password - and always prompt the user for both when running up?

From a macro I am accessing a command that is on the toolbar:
Dim name As String = "Macros.MyMacros.MyMacros.ToggleExceptions"
Dim cmd As EnvDTE.Command = DTE.Commands.Item(name)
How do I now change the caption of the command on the toolbar? It does not seem to have the necessary properties. Do I need to cast it to something else?

I am trying to write an onclick event for textbox but VB.net does not seem to support textbox1.click(). I want to open a new form every time someone clicks on the textbox. Opening a new form is no problem, but I cant detect the click. Is there any event for textbox that detects click event? I saw something like TextboxBase that has Click but I am able to use it well.
This is how my class looks :
Partial Public Class TextBoxClick
Inherits System.Web.UI.Page
End Class
It has some basic load and init events. I am trying to write a Sub like this :
Private Sub incident_clicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Incident.OnClick
Incident.Click does not work either.
I am guessing I need to import some class to access the Click event but I am not sure which.

I have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

I need to force a DataGridView cell to update the underlying DataTable.I fill a DataTable using my adapters Fill method, then set that DataTable as my DataGridView's datasource. Lets say one of my DataGridView columns is a CheckBox column.If I left-click a checkbox in the first row and then left click a different row in the DataGridView the underlying DataTable_RowChanged event fires, which tells me the first edit I did has gone to the underlying DataTable.If I left-click the checkbox in a row and then right-click the column header to display my context menu the DataTable_ RowChanged event doesn't fire because the DataGridView row is still in edit mode.I've tried Me.DataGridView.EndEdit(),but that doesn't cause my RowChanged event to fire,I need to ensure my underlying DataTable matches the data in the DataGridView, because I am getting a subset of my original table.[code]

I have a DataGridView bound to a DataView. The DGV is setup for FullRowSelect and is ReadOnly. The first column contains a CheckBox to show that the Row is ready for processing. The user double-clicks on the row and the box is checked in the CellDoubleClick event. This works great.
I have a RadioButton on the page to hide any checked items. This allows the user to only have to look at the work that needs to be done. I use a filter on the DataView to make this happen. At the end of the CellDoubleClick, I call my ApplyFilter method, but the current row still shows up.
I got around this once before by writing some code to see if I needed to move forward or backward a row and also compared if there were any rows available, etc.
It seems to me that this relates to the value not being persisted back to the DataSet until the CurrentRow is changed in the DGV. Is there a way to force this data back into the DataSet without having to programatically change the value directly in the DataSet?

I have a combobox where the SelectedValue on the combo is bound to a property on a business object.Everything works fine, but the property that's bound to the SelectedValue on the combo only gets updated when the focus leaves the control. I understand that the property doesn't get updated until the control is validated (loses focus), but I need it to update the datasource as soon as the dropdown is closed.I know I could probably leave focus from the control on the DropDownClosed event but I'd prefer something a little less kludgy.What's the best way to immediately update my datasource when the dropdown is closed?

I have a label inside an update panel which I wouldl ike to use as a status bar.Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.:
Stage 1: Retrieving data...
Stage 2: Calculating values...
Stage 3: Printing values...
Stage 4: Done!
I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work).I've been looking into timers and threads to try and update the panel separate to the main function?

I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.

Here's my code
Dim suppQuery As String = "SELECT [Supplier ID],[Company],[Last Name],[First Name],[Email Address],[Mobile Phone],[Office Phone],[Address],[City],[ZIP/Postal Code],[Notes] FROM [Suppliers]"
Dim dsSupp As New DataSet
Dim daSupp As New OleDbDataAdapter(suppQuery, cnPharma)
[CODE]...
It errors on the da.Update line and by the way if it helps, the text fields are a product of datarowview. that is when you select an item on the listbox the details of that appears on the text fields. and my goal is i could edit those text fields and save them.

So, my application has multiple text boxes for entering different numbers. Only numbers..
One problem I've run into is that I get an error when a textbox is totally empty. If I throw at least a zero in there, it works fine.
How would I make a textbox display "0" when someone deletes everything in the text box? I don't want it to be empty, I just want it to show zero.

I need to insert an event name and event time in VB so it starts showing the countdown to that event but the event can only be during the same day ie max countdown is 23h59m59s, but I've run out of ideas. Additionally, how can I force a textbox to a certain format eg so it only accepts numbers and puts them in a pre set format. For example when I press 111111 it sets it to 11:11:11 and 6 is the max amount of numbers in the box.

How do I make a program run only when it is executed with a command line? For example, if you press WINDOWS KEY + R, and then type in
"firefox.exe -profilemanager"
It will open up Firefox's profile manager. How do I make my program do that, except, if it's command line is "program.exe -letmein" it'll open form2. And if it's opened manually, (by doubleclicking or anything else) it'll open form1.

I am creating a form that creates new users and then updates them to a dataset, I have done this ok, but I am getting a runtime error when I delete a record. Please see below the exception being thrown
"Update requires a valid DeleteCommand when passed DataRow collection with deleted rows"
My code below
CODE:
So I know I need to add a delete command, but how do I write this in code and do I write it in the saveitem click event? I guess I would because the app crashes when I click save to update the dataset.
