I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

View 3 RepliesHow do I catch the new added datarow event? I'm using a dataset and bindingsource. I've tested Bindingsource's ListChanged event but it is a bit problematic. For example when I use those codes in the ListChanged event:
If e.ListChangedType = System.ComponentModel.ListChangedType.ItemAdded Then
MessageBox.Show("Record was added..."
End If
... records are added twice. If there is an another event for it?
I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String

View 2 RepliesI'm adding multiple combobox controls to a form dynamically, but am having a problem with one of the event handlers. The first event handler I've added (for the Leave event) fires, but the second (for the TextChanged event) does not. I've tried reversing the order when adding the handlers and I get the same results (TextChanged does not fire). Here's a code snippet for adding the controls, and the code for the events. I've added a breakpoint while testing to verify - but it never hits the code.
Dim cbo As New ComboBox
cbo.Name = "cbo" & fldName
cbo.Tag = fldName.ToUpper
cbo.Top = rowtop
cbo.TabIndex = tabOrder

View 3 RepliesI do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.
Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag
I have successfully added textboxes to a form at runtime. I have also succesfully added an event handler to these same textboxes. What I'm having trouble understanding is how to refer to these textboxes programmatically after they have been added. Specifically, how do I;
1) Retrieve user data entered in those textboxes without an event handler
2) Find a specific one of those textboxex later (is looping thru all controls of type "textbox" the only way)?
purpose of find is so that I can set the value of the corresponding textbox programatically, based on some criteria Here is the code (all within in a for loop, where intvararycount is incrementing to a set limit) I have used to add the Textboxes to a Panel on a Form;

I am currently working on a asp.net page coded via Visual Basic.On the page I have these image buttons that are dynamically generated based on the SQL Data the page retrieves.Unfortunately I could not figure out how to bind a click function to each of these buttons.the [Control Name].onClick = "Function Name()" is for clientSide scripts.and I need to bind
Protected Sub Button_InsertNewTextBox_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_InsertNewTextBox.Click
to the dynamically allocated buttons.
i guess the title pretty much states the question but i will give the senario to be more clear. i have a mousemove() event which i add in my program programmatically and i need a way for raising that event (again) programmatically too. raiseEvent control_mousemove() doesn't work as it says that "'control_MouseDown' is not an event of 'main'."

I've made a SCADA system with VB.net and AdvancedHMI, which is a program that monitors plant equipment etc.I've also made an alarm logger which out of a listview, so, when an alarm comes in, say "Alarm 1", en entry gets added to the list view as an "Active" event.
If the alarm clears, then another "Cleared" event gets added to the listview.This works OK, but when you start to get lots of alarms, it's difficult to determine which alarms are actually active, because you may have multiples of the same alarm.What I want to do, is to be able to press a button, which looks for when there has been an "Alarm" event and then a "Cleared" event for the same alarm, and then removes both of them from the listview. So it should then show only active alarms.I know that maybe a listview possibly isn't the best choice for my ultimate goal,
