I have field NAME nvarchar(5),Checkval bit in sqlsever. I want to bind already to Datagriview in vb2005. When I check filed checkval. It will to do something that I need. I don't want to use event cellmouseclick or cellvaluechanged because it didn't react when we click. Which event that do transaction when we click check.
View 2 RepliesI 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.
Public Function GetArray(ByVal strDLFolder As String) As Array
If blnDone = False Then
Me.Show()
[CODE]..........
Right now I'm setting a create a boolean switch when btnSubDone is clicked. What I would like is for something along the lines of:
[CODE]...........
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)?
I have a validating event for a txtbox called txtname. If the user tries to leave txtname for another txt box without entering their name a messagebox comes up giving an error. I have an exit button which will when clicked ask you if you really want to leave then you can choose yes or no. I can't seem to figure out how to allow the user to click the exit button while leaving the txtname blank so it would bypass the error message and only bring up the exit prompt. Here's what I have coded for the validating event and the exit event.
Private Sub txtName_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles txtName.Validating
If IsNumeric(txtName.Text) Then

I have a Combobox1 and Label1 in a form. There are items in ComboBox1 which is integer from 1 to 9. I want the user select the number in the combobox, and the selected number will be * 2. The answer will be shown at Label1.Text without any Click Button Event.
View 2 RepliesSo I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use:
Dim int As Double
int = button1.Left / Me.Width ' this = 0.2
'resize event
'Button1.Left = (int * Me.Width)
TextBox1.Text = (int * Me.Width).ToString
The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?

View 4 RepliesI'm having a strange problem with the OnClick event. In an ArcGIS application using VB.Net, I have a button set up with the following
AddItem("CommandAnalyseResults")
The following module segment contains the OnClick event: Public NotInheritable Class CommandAnalyseResults
Inherits BaseTool <more code...>
Public Overrides Sub OnClick()
[Code]...
The OnClick event gets triggered no problem the first time I click on the button. However if I then close the window the button code creates and then click on the button again, the OnClick code is not triggered.
If I click on a different button then click back on the 'problem' button a 2nd time, it does seem to trigger the code!
I am trying to write a program using Visual Basic 2008 Express Edition that will automaticlay generate multiple Command Buttons that have different Texts and perform different commands.For example I want to generate Button_1 and Button_2 where Button_1 when clicked enters the value "1" into a textbox and Button_2 enters the value "2" into the same textbox.I know this can be simple done by using the designer and wirting the code in the Button_1_Click, but what I want to eventually achieve is for various buttons to be generated across different Tabs in a TabControl.So far I can create a button on a windows form using code, but the button has no purpose so command is assigned to it. The code i've used is listed below:

I get this error at the Commit of a transaction in a desktop application:
This OleDbTransaction has completed; it is no longer usable.
Other posts I have seen with similar error suggests this can occur if it takes a long time, or contains large amounts of data. This is not the case here.Logging tells me it takes 140 ms from Begin to Commit and about 10 commands executed inside the transaction.It is using an Oracle database.This class is a simplified version of my database class:
Class MyDatabase
Private mConnection AS OleDbConnection
Private mTransaction AS OleDbTransaction

Is it not allowed to run a select inside a transaction like this? Or can it be done by running the transaction in a specific isolation level (I see that the BeginTransaction method has an optional parameter for doing this) ? ..Or some other sollution..? In my case, it was not a problem to move the select to run before the transaction started, but what if you need to run selects that must run inside the transaction?
I've seen plenty of examples of transactions in the actual store procedure's SQL. But I'm wanting to do the transaction and keep track of it in code. I tried this but it says that my insertcommand's transaction object is null. How can I fix this?
vb Dim conn As SqlConnection = DBConnections.SQLServerConnection
conn.Open()
Dim params(1) As SqlParameter
[CODE]....
What is this kind of exception?
Error : Execute requires the command to have a transaction object when the connection assigned to the command is in a pending local transaction. The transaction property of the command has not been initialized..
This one causes the error: Dim oOperation As COperationOutputTypeBS
oOperation = COperationOutputTypeBS.GetOperationOutputType(txtOperationCode.Text)

How can you chnge the location of a ovalshape using button and 2 textboxes in a button click event
View 1 RepliesI believe there wont be any diff if user clicks the button on the form and the click event is fired OR if we call the button click event / function in the code. Because in one my project, this does make diff. If I click the button on the form, the App works great but same button if I click it thru the form code, the whole process crashes. This happens in Vista / VB.net.
