View 1 RepliesMDI Child Forms Not Interacting
May 11, 2012I have a MDI parent on which i launch a child form
Dim NewMDIChild As New Frm_addOT
'Set the Parent Form of the Child window.
NewMDIChild.MdiParent = Me
'Display the new form.
NewMDIChild.Show()
His child form contains several comboboxes which hold data from a dbase(sql)
When new data is entered in the cmb it checks the database and if it isn't in there it launches another window
FRM_OTlistaddklant.Visible = True
and copy's the newly entered text in a textbox.
FRM_OTlistaddklant.TB_klantnaam.Text = OTaddklant_naam
then i can give in the details etc.
now, when this is done and the users presses a button "Add"
the information is written to sql(which works perfect)
than i have a public sub on the Frm_addOT which should refill the combobox and
also set the backcolor to a specific color.
and the last two things will not work. Actually when i try to change the backcolor on Frm_addot it triggers the event backcolorchanged and says it has changed but it is not visible.
Multitasking Interacting With UI Thread?
Oct 1, 2011I'm trying to start to use the Task class for multi-threading. This is a really simple example so I can work out the ins and outs. As an example, I have the below thread, the thread.sleep is used to represent large amounts of data processing, at the end of which I'd like to update something on the screen. Please advise a good way to achieve the idea of the below code with respect to the text box update.
With the old threading system, I would grab the UI context, and do a .post/.send to it. I'd like to have that ability with the newer task system, but am open to the preferred way of solving this.
As a back ground, the threads I will be replacing were previously constantly running during the app with a do/while that was killed at app close.

View 1 Replies.NET COM Assembly Interacting With Excel Via BackgroundWorker?
Feb 24, 2011I am writing (and teaching myself how to write) an experimental assembly in VB.NET 3.5 that is exposed via COM and then called from some Excel VBA code to initiate an instance of a class that traps some Excel events and then perform some functions on the active workbook in Excel.To initiate the class, a reference to the Excel Application is passed from the VBA (I am using a PIA for Excel in the assembly).I needed to perform a time-consuming operation on the active workbook from my assembly so I decided to use a BackgroundWorker in a WinForm so that I can display a progress dialog for the operation whilst the operation completes in the background.
I would like to know if there are any problems with interacting with Excel via COM using a background worker in this way? Reason for asking is that the main class in the assembly holds the reference to the Excel application object, and this is then passed to the BackgroundWorker so that it can determine the active workbook and then perform some operations on it. I am only accessing the workbook itself (not other objects) through one procedure.

VS 2008 Interacting With Other Windows Applications?
Jan 9, 2010I didn't know where to post this question so I hope I put it in the right forum...I am not new to Visual Basic, however I am definitely not an advanced user. I would like to build an application that would allow me to interact with other programs on my computer. For example, if I were to build an application that could control iTunes, how would I go about this?
Or, I am looking to make an application that would allow me to do little things on my computer like disable my track pad if I have a mouse plugged in. How would I build something that could interact with windows (or iTunes) like that?
