I want to insert data from two tabs on a Tab control into a Table and I keep on getting Run-time error 3134. I believe I have to in someway make all the Tab active but don't know how. Below is my code
Private Sub SaveandNew_Click()
Me.tb_Factors_Treatments.PageIndex = 0

I'm trying to make a simple User control that houses one collection of a class that I've made. After building the control All works as planned and then randomly when I try to go to the design time interface for the form I placed the control on I get an error page with the following:
To Prevent Possible data loss before loading the designer, the following errors must be resolved:(ignore and continue: which about half the time works and the control shows up and the other part of the time all of the controls on the page are missing)
The one error is the following:Object of type'System.Collections.Generic.List'1[StaticGraphPlot.clsStaticCurveData]' cannot be converted to type System.Collections.Generic.List'1[StaticGraphPlot.clsStaticCurveData]'.

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.
im using the timer control, how do i set the start time and finish time? for eg, show a label text for 4 secs then hide. Googled for examples but still no joy.

View 2 RepliesI have a form with the DateTimePicker control on it. When I select a date it gives a value like "date time" (Eg.: 5/12/2010 12:20:35 PM). But here the time returned is current time. What I need is for the date chosen from the picker automatically set the time to 00:00:00 instead of the time when the date was picked.

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?

I have a blank winform. A textbox control with name textbox1 being added to the winform. During the form load event, I retrieve 2 string values from database and store these values into TextboxName and TextboxValue variables of string type.
I use TextboxName variable to store that textbox control name (i.e. currently TextboxName = "textbox1") and TextboxValue variable to store that textbox's text (i.e. currently TextboxValue = "Hello world"). My question is how to set the textbox1.text property without have to resort to following code:
If TextboxName = "textbox1" Then
textbox1.Text = TextboxValue
End If
how to set the textbox1.Text property without have to use IF...Then construct?

View 3 RepliesI am trying to create a ListView control at run-time and populate it with data from a SQL Query, I can create and execute the SQL query returning my desired data, I can create the listview control, but I can not get the list view to Populate data from the ListviewGroup I am creating from the SQL query. Code Snippet Follows.
Dim ItemGroupSQL As New ListViewGroup
' Create three items and three sets of subitems for each item.
a = 0
[Code].....
This will create a ListView Box and populate the data in a very odd way, every row will have 5 columns with the same data repeated in each column. I have verified (using the commented out msgbox statements you see) that the ItemGroupSQL variable is being populated correctly. but Listview1.items.addrange(itemgroupSQL.items()) does no add the data to the listview correctly
Am I using incorrect syntax for Items.Addrange?
