VS 2008 All Property Of Button1 Set To Button2 (Run Time) Where Button2 Created At Runtime?
Feb 23, 2010
I put a button control name 'BTT1' on form and all property are set through property window..and In form_load events i want to create 10 more button which property are same as 'BTT1' so how i can assign all property of 'BTT1' through one or two line of code ...like
--------------
for i=1 to 10
dim b as new BTT1
b.name = "b" & i
[code]....
All Handles of new created button also assign to handle of BTT1 (more clear: all subroutine handle mousemove, click, etc of BTT1 also works for new created Button (b1, b2 ...b10))..

start with I was given a program by a friend that was created in Excel 2003 with the help of Visual Basic Editor. He said he used Visual Basic 2003, which he is not 100% sure about. Anyways he used CurLine in the program and when I try to open it in Excel 2007 and then open the Visual Basic Editor and run the program I get the following error:Run-time error '-2147418113 (8000ffff)':Could not get the CurLine property. Unexpected call to method or property access.

I've created an SQL Query using the query builder. In the query builder, you can test the query by clicking the button "Execute Query", and entering the desired values in the parameter fields.
My query returns the correct results when I do this, but when I seemingly pass the same values at runtime, I get 0 records returned.The query is designed such that you can pass nulls if you don't wish to filter data by that particular parameter.
SQL Query:
SELECT ID, UPC, Quantity, Manufacturer, Style, Color, Size, Category, DateReceived, Cost, OriginalRetail, Retail, LocationID
FROM Inventory
WHERE (UPC = @UPC OR
[code]....
In the query builder "Execute Query" dialog, I enter a value I know that the db contains in the "Size" field, "1/1/1900" & "1/1/2199" in Dates A & B, respectively, and nulls for all other fields. This returns 1 record, which is just as I expected. It works correctly.But when I pass the same values into the method created by the designer, I get 0 records returned. I can't figure out where the problem lies. Even if I enter nulls for all fields other than the dates, it returns 0. This tells me that the dates are causing the problem, but I can't figure out why, because I'm passing strings equivalent to what I entered in the query builder.

I have a listbox binded to a list of objects. For each list item I wanted to have a rectangle whose fill color is determined by a few properties of the binded object. So I did the following:
Made sure INotifyPropertyChanged was implemented on my object.Created a class to expose the properties I am interested in as attached properties.Binded the properties of the object to the attached properties of the rectangle Created a style that uses triggers to set the rectangle fill based on attached properties.
This works, but only the first time the property of the object changes. After that, the attached properties do not seem to be receiving notification when the data object's property changes. I have double checked and my data object is raising the INotifyPropertyChanged event.
<Rectangle Style="{StaticResource RecordStateRectangleStyle}"
Width="10" Height="10" Stroke="Black"
local:RecordAttachment.RecordState="{Binding Path=RecordState}"
local:RecordAttachment.IsDeleted="{Binding Path=IsDeleted}" />

i have created dynamic buttons at runtime and i would like to disable them when a user clicks on a form button.This is the code i have for that button:
Dim intXX As Integer = 0
Do Until intXX = intX
userAvatar(intXX).Enabled = False
intXX = intXX + 1
Loop
The buttonNames is an array of all populated button names created at runtime. However, trying the .enabled = false at the end of that does not work. What other ways are there to do that with buttons created at runtime?

I'm trying to develop a program that turns matrices into their reduced Echlon forms. The user specifies the number of Columns & Rows for the matrix, which is generated by the following Sub Routine
Private Sub ButCreate_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles ButCreate.Click
'Columns and Rows are specified by the user
rows = TxtRows.Text
columns = TxtColumns.Text
'clears all of the controls(text boxes) from the TableLayoutContainer
[Code] .....
How to do is access/manipulate those newly created textBoxes. After the user enters values to those boxes, I want to assign each of their columns to an array.

I am using the follwoing code to generate Menustrip at runtime.
Dim dgv1 As DataGridView
dgv1 = Me.MenuDataGridView
ReadMenuInGridView(dgv1)
Dim MItems As New SortedList(Of String, ToolStripMenuItem)
For Each dgr As DataGridViewRow In dgv1.Rows
[Code] .....
Where the sub "ReadMenuInGridView" passes the DGV by reference and populates it with the menu item from the database. My question is,, the program as it is in the form listed above works fine (where I have a DGV "MenuDataGridView" created at design time), however, if I want to make it 100% dynamic and use a DGV created at run time I will not get the menu? Actually the program will not get in to the For loop?
Simply to do that we can replace the first 2 statement with:
Dim dgv1 As New DataGridView
'dgv1 = Me.MenuDataGridView

Been searching a trying examples for a couple of days and always fall back to the "null reference" error on this one. I have a set of instructions coming from a SQL database and the number of instructions is a variable. Therefore, I have a TabControl which I add TabPages to at RunTime depending on the number of instructions there are. The TabPages are then created with the names; Step1, Step2, Step3, etc.Each TabPage is made with the same controls and all of the controls are named the same from page to page (e.g. "instr" is the name of a TextBox control that exists on every TabPage).I can successfully create a GetControl method that will return the correct TabPage, but I cannot reference any controls on that TabPage.I can only change properties of the TabPage.If I try to reference a specific control on that TabPage, like the "instr" TextBox control, I get the null reference error.[code]

As you can see, i can retrieve the tag of the button (which is created at runtime) without any problems, i've made a temporary msgbox to show me the value of the tag, just for testing purposes. What i do have a problem with, is retrieving the tag of the individual web browsers, how should i do this?
Next issue, how would i code for my buttons to show the web browser with the same tag as the button that's just been clicked?

My program creates columns at runtime with the following code:
Cmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
objCmd = New OleDb.OleDbCommand("ALTER TABLE [Parent] ADD [" & ColumnDate & "] int", con)
objCmd.ExecuteNonQuery()
I add data into the newly inserted column with the following code:
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
Dim cb As New OleDb.OleDbCommandBuilder(da)
cb.QuotePrefix = "["
cb.QuoteSuffix = "]"
ds.Tables("SchoolMaticsDatabase").Rows(inc).Item(ColumnDate) = Hours * Num
da.Update(ds, "SchoolMaticsDatabase")
All of the above works fine; the issue arises when I try to edit the information originally placed in the newly added column. These are the approaches that I have taken. (None of them give an error message; it simply won't update within the database.)
da.SelectCommand = New OleDb.OleDbCommand(sql, con)
Dim cb As New OleDb.OleDbCommandBuilder(da)
cb.QuotePrefix = "["
[code]....
I added a column to the table manually via opening the access database and all the above approaches work for editing data stored in that column. So I believe it is something to do with the fact that the columns are created at run time.
