BackgroundWorker is the best thread class, I've found. It can send progress information back to your main thread, and calls back into the main thread when it's done. If your program should stop taking input during the process, have a progress dialog go modal, and call the thread, and not offer any way to close until the thread is done. You can also cancel a thread using the BackgroundWorker.

Hi,
I have a problem with an error.
I try to use thread in my program:
Dim t As New Thread(AddressOf conv_str)<br />
t.SetApartmentState(ApartmentState.MTA)<br />
where conv_str is the function where I need a thread
and the error is:
"Overload resolution failed because no accessible 'New' can be called with these arguments:
'Public Sub New(start As System.Threading.ParameterizedThreadStart)': Method 'Private Function conv_str(str As String, provider As String) As String' does not have the same signature as delegate 'Delegate Sub ParameterizedThreadStart(obj As Object)'.
'Public Sub New(start As System.Threading.ThreadStart)': Method 'Private Function conv_str(str As String, provider As String) As String' does not have the same signature as delegate 'Delegate Sub ThreadStart()'
If you have an ideea please help.
thanks

Well, the error is exactly what it says. The only threads you can start are ones with no parameters, or take an object. So, create a struct to hold the values you want to pass, and pass them through that, so conv_str takes an object, not two strings.

Hi,
How can we display the image which is in packedDIB format, in a picture box in VB6.
note: packedDIB contains a single pointer which points to a memory block containing a BITMAPINFO structure which is followed by the image data.
Basically I will get the image in packedDIB format(its a 6 or 8 digit number iam getting. i think, this is the memory address.). I need to dispay the image in picture box using this packedDIB.
Please anybody give me the solution. Its very urgent for me.
Thanks in Advance,

Is there anybody could tell me how to read/write data from/to USB Serial by Visual Basic
|
|
|
|
|
You don't read/write data to the port, you do it to the device attached to the port. How you do this depends on the device itself and what methods it exposes.
Since you mentioned Serial, I assume the device exposes itself as being attached to a COM port, in which case, you'd be looking for examples on Serial Communication.
|
|
|
|
|
Oh,I see!
I guessed I can not read/write data to the port,too!
But my friend need to do it,and she tell me nothing about the device.
Thanks a lot!
Let me try another way to do it,
or if somebody has another good idea,tell me,please!

Like I said, you don't talk to the USB interface directly. You MUST have some API to talk to the device itself. Without knowing anything about the device, there's nothing you can do that will work.

This is not like a serial or parallel port where you can talk to any device plugged into it just by talking to the port.
USB is a BUS, not a port. You have to address devices to talk to them. This is something that is left up to the driver of the device. Like I've said before, you need to know about the device and the API exposed by either the driver or some SDK for the device.

"MSComm" control is not use for USB Port

Hi all,
I'm trying to create a database application that is getting data from access database.
I want to show a list of data in combobox. What i need to do is to have the ability to add and delete from my form. What is the best way to do it? I want the combobox to update every time I added or deleted an item.
Thanks in advance

hi,
use following code
private sub fillCombo()
sql = "select name from table"
mydataadaptor = New OleDb.OleDbDataAdapter(sql, con)'where con is connection object
mydataset = New DataSet
mydataadaptor.Fill(mydataset)
combo1.datasource=mydataset.table(0)
combo1..DisplayMember = "name"
end sub
one more thing after each insertion or deletion use following statement
combo1.datasource=nothing
call fillCombo
hope this helps

it depends how complex you want to go but what if someone else has already edited a name in the table - how do you stop it overwriting the previous change?
