Currently i have a combo box with a single select and can also enter a text.
Now i need to select more than one from the combobox. Just like our listbox functionality. How to implement without changing the UI. After selecting the items from the listbox and when it is double clicked, the selected items should be shown in the combo box.
I have a way. But it looks tedious one.. I'll explain it in detail...
I have a textbox and combobox (width is reduced to show only the down arrow). So for the user it'll look like combobox only. And when the user clicks on the downarrow, we can display the listbox and allowing to select multi select.
Is this the way that it can be done.?

Ummm...The ComboBox doesn't support multiple selections. You'll have to use a different control that does, like maybe a CheckedListBox.

Hi,
I have been working on a VB.net project. where I want to use drag and drop controls. Right now, I can able to create the controls on runtime with following code
Dim btn as new Button
me.controls.add(btn)
btn.location=new point(23,34)
btn.show
like..
The only problem is how to move the controls (command buttons) on the form to place it right place on the form.
i tried mouse down and mouse up methods to do it. But, the button created in one event handling sub routine is not Available in other sub routines.As i am declaring it as private sub routine.(I need a global runtime button to be created in a event method so that other event procedures also shared that button).do u understand?
Please help me in this regard.
Thank you

Why don't you use the 'Drag & Drop' options in .Net which you can link to the events of the control during the creation. After this you don't need to know anything about the control as it aranges the drag and drop himself.
All you'l have to do is link some private functions that deal with the drag & drop to the related events of the control and you're done.
Good example: MSDN article

Thank you for your reply
The solution showed in the MSDN is ok. But I need a control to be created at runtime and add mouse events to it (double click event).
In the MSDN example case, textboxes created on the form are type friend with event. so all the events are handled by with events method.
But, ,if I create the textbox at runtime ,how do I write the code for event handling?
Can you please explain me with sample code?
Please create the control at runtime and do other tings (drag&drop and move).
Thank you,
ramesh

The below example is for binding the double click event to a function, but you can use a similar method for all events.
sub CreateControls()<br />
Dim cnt as Control = new Button();<br />
' Add placement logic the usual way<br />
AddHandler cnt.DoubleClick addressof onDoubleClick<br />
End Sub<br />
<br />
private sub onDoubleClick(sender as object, e as EventArgs)<br />
' Execute double click code<br />
end sub<br />
For more on events see: MSDN help
Note you will have to bind the drag & drop functions if you choose to use this option.

Would anyone happen to know how to transfer any file through a networkstream, sort of like
'Load image wanted to be transferred<br />
Dim TP As Image = Image.FromFile(Path)<br />
'Save to stream to be transferred<br />
TP.Save(NetworkStream, Imaging.ImageFormat.Jpeg)<br />
TP.Dispose() 'Get rid of it
Except for any file (images, etc media(avi,qt,bmp,etc), plaintext files, executables, etc).
I've been looking at the other classes in system.io but nothing I've tried has worked so far.

Sorry for being so long to reply. No, that isn't exactly what I am looking for, although I sort of found my own answer. I was able to send images etc by using a filestream and a binaryreader with readbytes, but that doesn't seem to work with any other file type. The output is slighty different from orignal file, if you could help me figure that out.

I have not many clues of what to do... I'm using VS 2003 (VB.net)
I'm trying to create controls on the fly, creating them is just fine. But if I afterwards want to change one of them, how to make that possible?
This code is just a simple example:
Private Sub Beginner()<br />
For i As Integer = 1 To 10<br />
Dim p As New Panel<br />
<br />
p.Name = "pnlThing" & i<br />
p.BackColor = System.Drawing.Color.Blue<br />
p.Size = New System.Drawing.Size(10, 10)<br />
p.Location = New System.Drawing.Point(10 * i, 10)<br />
<br />
Me.Controls.Add(p)<br />
Next i<br />
<br />
End Sub
Is there a way to make a reference so I can use pnlThing1.*method*?
Regards,
Hmmkk

You can iterate over the Me.Controls collection and do a comparison of the Name property with the name that you want to find. Then, just use that control.

Hello! 
I put a password for my access database while I have developed my application and then I decided to update connection strings in design mode.
"I defined OLE JET DB" and test the connection with password but
it failed. It was asking for a workgroup file, which I created so but
it didn't work out again!
Do you have any idea how can I set a password protected connection string for
access database? I am using XP professional.

how can i change Character Pitch of a dot printer?
|
|
|
|
|
See the manual on the printer for the exact character codes you have to send. You, of course, must be sending data to the printer directly and not using the Print objects in the .NET Framework.

When i printing raw data from Laser jet i got this error.
How could i control which printers can print raw data , before to show printer list will be print documant
ERROR :
A call to PInvoke function 'RawPrinterHelper::OpenPrinter' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

|
|

The error means precisely what it said. You got the Declare statement wrong when you declared the parameters for the OpenPrinter function call.
OpenPrinter[^] on pinvoke.net.
