Cheers for that.
When I read a value that is binary, i cant out put to a label, but is it possible to check the value against 5 or 6 others and set a list box value depending on the outcome?

I'm not sure what you're asking ? A binary value is a bool, or do you mean a value that is data other than a string ? You can certainly compare a value to a collection of values, if they are all of the same type or there is an acceptable conversion.

K for example i read a value which is 'REG_BINARY' and the value can be 01 28 00 08 or 01 00 40 0a. I need to compare the current value to like a list of available values that can be set. Now if i need to convert, that is the part that i will definetly get lost in.

What sort of variable are you storing that in ? It looks like a byte [] to me.

i just used byte as an example, am not sure what to store it in

OK, well it looks like a byte [] to me, not sure how else you're store it. But if it's in the registry, the registry API will assign a return type. Whatever it is, store your values to compare as the same type, then you can compare them.

Cheers for the help, i use the following code now which works:
Try
audiospeakersrightclick = Registry.CurrentUser.OpenSubKey("SOFTWARE\NVIDIA Corporation\NvMixer\Profiles", True)
If audiospeakersrightclick Is Nothing Then
combospeaker1.SelectedIndex = 0
combospeaker2.SelectedIndex = 0
audiospeakers.CreateSubKey("Profiles")
End If
Catch ex As Exception
End Try
Many thanks again.

k sorry bout this but I am having the same problem when reading binary values from the registry. Here's the code I am attempting to use:
Dim showadvanced, showfirewall As Byte
Try
nvmixersettings = audiospeakers.OpenSubKey("Settings", True)
showadvanced = nvmixersettings.GetValue("ShowAdvanced")
showfirewall = nvmixersettings.GetValue("ShowFirewall")
If showfirewall = Nothing Then
soundstormadvancedenable.Checked = False
soundstormadvanceddisable.Checked = True
soundstormfirewallenable.Enabled = False
soundstormfirewalldisable.Enabled = False
GroupControl13.Visible = True
End If
If showfirewall = 10000000 Then
soundstormadvancedenable.Checked = True
soundstormadvanceddisable.Checked = False
soundstormfirewallenable.Enabled = True
soundstormfirewallenable.Enabled = True
GroupControl13.Visible = False
End If
Catch ex As Exception
End Try
Now i have tried to Declare the variable type to string and byte and still no good, any other ideas??

hellow to all ..
i am trying to chain a textbox name ,
i is integer ..
like textbox&"i"&.text
how can i do it ?
|
|
|
|

Wow - that's bizarre. To do that, you need to build the string first, then use reflection to turn it into a textbox instance. The neater way would be to build a hash table of indexes to textboxes. Oh, and if you put i in quotes, you get i, not i as an integer variable value.

I keep getting the following error when trying to delete a row from a dataset using a datagrid (specifically the last row in the datagrid) :
An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll
Additional information: Object reference not set to an instance of an object.
Any ideas?
I know the err could be caused by a lot of things but..
Why just the last row?
If I start deleting records from the top, I can even delete the last row...but not just the last row ..

I have written an application in VB.Net to be run in Windows CE. In it I have a combo box that is populated with numbers representing items that the user will select and use and are then removed from the list. Specifically, a file is maintained with all the numbers that could be in it and a flag is set that tells the program whether a particular number has been used or not. Every time we return to the screen with the combo box on it, it is repopulated.
When we get down to having only 3 selections or less available, the combo box opens when the down arrow is clicked and immediatley closes before a selection can be made.
Any suggestions as to how to correct this problem?
Also, the point at which this problem occurs changes when certain things are changed about the combo box. For example:
The font for the combo box is 9pt currently. If I change it to 12pt, the problem doesn't occur until we get down to only 2 items in the list.
I also moved the box to a different location on the screen and it started occurring with 4 items left.
Any help would be appreciated.
Thanks,

is there any way to, when adding subitems, to skip over a collum and put data in another. Say for example you have 6 collums and you already have data in the first 2 collums and want to skip the 3 and put data in every collums after 3. how would you do this?????

Hi everybody
I need some help! I created an AVI animation to display in a form
but i can't understand what color I need to use to have the background
transparent (the mask color). I tried with FUCSIA but it doesn't work.
I designed the bitmaps with Paint and converted to AVI using Virtual Dub.
Any Idea?
Thanks in advance
OS: Win 2K
SDK: Visual Studio 6/Visual Basic

IIRC, you can't set a transparency in a movie and expect to see the form behind it. The WMP control that's displaying the movie doesn't support a transparent background, if that's what your using.

I'm using the animation control (part of MS common controls). The strange thing is that with sample movie clips in Visual Studio (for example, the file copy or computer search) the trick works good. The AVI has a fucsia background and the color of the form behind is displayed.
What do you think? 
thanks in advance Dave

I've never used the thing.
But, I've found an abscure reference that says that the pixel in the upper left corner of the first frame becomes the transparency key color. But, this does NOT make the AVI transparent, rather it substitutes the parent containers background color (in your case, the form color) for each pixel that has the transparency key color. This makes the background color (or transparency key) match the host container color.

That's amazing!!!!
It's what I was looking for!!! In fact I don't need to have my AVI with a transparent color but I only want to use it with a masking color for the background.
Thanks a lot Dave
