I have a form which is a loading form. I would like it to close and remove itself from memory before the next form (Login form) LGNFRM loads.
The problem is, is that the form hides itself rather than closes as when I press ALT-TAB to change windows, the form that should have closed is till open, but you cannot access it unless you close the login form. Could anyone help?
Using VB.net 2005
In the end we're all just the same

Hi Dave,
I am going to assume that you want to remove the first form from memory because it uses a lot of resources itself.
In this case you have to "cheat". Make a new completely empty starting form, have its load event open your second (loading) form, and then hide itself. Then make your second form open the third one in its disposed event, and use me.dispose, instead of me.close.
Et voila.
Johan
My advice is free, and you may get what you paid for.

you can get The MdiClient Control of your form and set background image for it:
Private Sub MyMDIForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
For Each c As Control In Me.Controls
If c.GetType Is GetType(MdiClient) Then
c.BackgroundImage = Image.FromFile(ADDRESS_OF_IMAGE)
Exit For
End If
Next
End Sub

1-MdiClent control has properties such as other controls; u can use BackgroundImageLayout property to set background image layout , use BackColor Property to set Back color , ...
2-by using Color.FromARGB you can create your custom colors and assign it to backcolor property

i have developed a "Voice Based Messenger" which user could record voice and send it to another user. i found difficulty in coding part to record,stop, playback and save it as an audio(.wav) file.
ill appreciate..thanks

Your program will be useless if it saves wav, that's raw data. You want to save as mp3.
You need the platform SDK to look at DirectShow.

You can still hook up an event. Is this ASP.NET or winforms ?

hi,
my application is in vb.net(winforms)

OK, then it's a lot easier. You should be able to attach click events to your columns, just by adding a click event in the column definition.

In that case, you should forget about datagrids, and work through a beginner book on VB.NET, just the language, not any forms stuff.

I've used VB.NET 2003 Standard to create a form using the wizard.
On the form, I had a bound textbox - txtUnitOfMeasurement.
This was bound to an MS Access table, tblSuppliersProducts, and a numeric field called UnitOfMeasurement.
This worked fine.
I then upgraded to VB.NET 2005 Express, and swapped my textbox for a combo box, and added the following settings to the combo:
Data Bindings - SelectedValue = tblSupplierProductsBindingSource.UnitOfMeasurement
Data Source = tblUnitOfMeasurementBindingSource
Display Member = UnitOfMeasurement
Value Member = MeasurementID
This too is fine, on my experimental dummy first record - it saves my changes to the UnitOfMeasurement field in tblSuppliersProducts - proving, to me, that it is bound correctly. However, when I press 'Add', it retains my previous combo box choice (which isn't a huge problem) on the new record, but when I fill in the remaining fields, and press Save, I get an error message saying that tblSuppliersProducts.UnitOfMeasurement is null.
I am obviously not doing something properly in between changing my text box for a combo box, but I don't know what.
Can you help?

Is your combo box perhaps binding again, and reseting the data source ?

Thanks for your reply. I'll have to have a look.
Unfortunately, as I'm developing the app from home, I don't have access to it in my "real" job!
Another problem is the seemingly unnecessary lines of code that the form wizard throws in. I'm pretty new to all this, which makes it that bit harder for me to read what its done.
Oh well - a bit of debugging to do tonight, then!
