There's nothing in the Windows API that will tell you this. You'd have to use a third party library, like Nero's SDK, to get that kind of information. Sorry, I don't have any examples.

Thank you,
I try to use Nero and getting this information but with no success.
Someone can help.
Thanks

You should have said that before.
Your best source of information is going to be a support board for the library that your using. I guarantee you that 99.9% of the people here have not used a CD Burning library.

Hello All,
Well i am working with collections in the project.
I have set the datasource property of the datagrid to a collection (I am not using dataset just the collection).
I am unable to format the datagrid using the tablestyles.
Would anyone please help me in formating the datagrid (using tablestyles) when the datasource property is set to a collection.
Thanks in advance,
P.S - I am unable to set the mappingname property in the tablestyle to collection.
if you send a mail at gokhale.i1@gmail.com in response to this query it would be better...

Hi, I designed my application in vb2005. I have a windows form application and contain combobox. My combo box contain an item and i set a dropdownstyle property to dropdownlist.
The problem occure when i try to delete the text from the combobox. I try to write the code combo1.text="" but the text still remain the combobox. Can anyone help me to solve this problem?
Thank in advance
|
|

|

try combo1.selectedtext=""
but why would you want to delete the text?
If it is because there is text in it the moment you start you form then you should put the selectedindex to -1
combo1.selectedindex=-1
you can also try
combo1.selecteditem=nothing
since you have set the property to dropdownlist the user can not type into it so the text displayed is whitout a doubt a item and therefor the selecteditem or selectedindex will most likly work best
If my help was helpfull let me know, if not let me know why.

Hey all!
I'm having an issue here, I have a panel whereby i draw my charts on it. Theres alot of computation done to have the charts drawn. So instead of runnning these computations again and again for everytime there's a repaint action, can i somehow save the stuff's ive drawn onto the panel and then when there's a repaint, ill just paint the graphics ive' saved ealier?
Thx in advance!

Draw it to an image then repaint the image.

It's a common technique. Create a Bitmap the size of your drawing area, destroying and recreating a new one of appropriate size as your control resizes, and draw everything to this buffer. When you get a Paint event, draw the buffer to the screen.
|

|

Alternatively, you can split your code in two parts:
1. do the lengthy calculations and save their results in some data structure, without
drawing anything, then call Invalidate()
2. in your Paint handler, paint the drawing based on the content of your data structure
You have to balance this approach to the one based on a hidden bitmap: if you need lots
of resizing, this approach may be more appropriate since you can resize analytically
rather than by the pixels. If your output is more of a painting than a drawing, having
a bitmap probably would be better.

thx all for the replies!
I'll use a bitmap and then redraw it out using but im yet to test it.
Ive' got another question to add; by implying the methods of saving onto a bitmap and redrawing it out smoothens the paint process? or i'll still be seeing flickerings like im seeing it now, its nth major actually but it just bothers the mind seeking perfection.! 
and the fact that when i actualy do systems testing, i would wanna push it to the limits.
thx again!
regards,
jensen!

Hi, I changed the connection string datasource property to "DataSource = ../../data/databasename.mdb" instead of using the hard coded location(i changed this connectiong string everywhere in my application using the search function and entering the connection name). Anyways...I can't preview my data anymore now but it records to the database correctly? I have had to change the design of my tables in my database and now need to regenerate my data set as well as table adapters(I used all the built in tools to generate this before). How do I go about doing this? I am using vb.net 2005 and writing a windows application. PLEASE HELP!!!

If you have your connection string in more than one place, then your code is probably a maintenance nightmare in other ways, too. You should consider a better approach in future.

Well I used the the vb.net "add datasource" to create my connections. I just searched for everything with that connection name in the application.Then i changed the connection data source to a relative path. Anyways how would I regenerate my datasets and table adapters?

I don't use the dataset desginers at all, so this may be wrong.
But, I think you have to manually add the new/modified columns to the datasets. Open your Data Sources window, or click on the Data Sources tab if you have it, right-click on your dataset/table and click on Configure DataSet with Wizard. You should be able to add/remove the new columns in there.

I can't seem to find a solution for this (and it's probably very simple)
Situation:
I have a combobox with a list(of string) as datasource
I've put the autocompletmode to append and the autocompletesource to listitems
everything works fine untill here
problem:
my users has to be able to type into the combobox but only text that is in the list
this works with a bit of code (check to see if there is text in the textpart of the combobox, if so check the list, if the list contains the text go on else clear combobox and start over)
but now when I start typing a word that is in the list the combobox appends the rest of the word (exactly like I want it) the only problem is that if I don't type the word out full the text that needs to be appended is not appended. The combobox only does this when I hit enter (this is not an option since the combobox is on a dialogwindow and hitting enter is accepting)
question:
anyone know how I can force the combobox to append the text when I leave the combobox (with tab)?
If my help was helpfull let me know, if not let me know why.

You could consider mimicking the combobox's behavior, in the leave event. If you do it with a little function, you would even be able to reuse it with other comboboxes.
Combob1.Text = YourLittleFunction(Combob1, Combob1.Text)
or
Combob1.SelectedItem = YourLittleFunction(Combob1, Combob1.Text)
and
Public Function YourLittleFunction(Byval combob as ComboBox, Byval TypedSoFar as String) as String<br />
'loop through the items in combob, and compare them with TypedSoFar.<br />
'Which ever comes closest is the winner.<br />
Return the winner<br />
End Function
Or something along those lines...
Good luck,
Johan
My advice is free, and you may get what you paid for.

thanks for the reply
turned out I was able to do it very simpel with the code already in the leave event (the code that check wheter or not the text exists in the list) apperently the text that is apended is already in the .text property the only problem I had was that its case sensitive and the text in the list was uppercase and the text entered lowercase.
but you're post did help me with forming an idee of what was going on so thanks...
just in case you are wondering how I did it here is the code:
If cboType.SelectedItem = Nothing And Not cboType.Text.Equals("") Then
Dim l As New List(Of String)
For Each s As String In cboType.DataSource
l.Add(s.ToLower)
Next
If l.Contains(cboType.Text.ToLower) Then
cboType.SelectedItem = cboType.Text
Else
cboType.Text = ""
cboType.Focus()
End If
End If
