I didn't install anything, while installing the hardware. XP itself updated the registry. Yeah, when I use the card reader, it populate the text box. But I want to do without text box.. Any suggestions?

You still haven't answered my question. What TextBox? Where did it come from? Did you put a TextBox control on the form? Is there a component that you are using to get data from the card reader? How did you get a TextBox control on the form that is displaying this data?

As a test, I just created new project and add new form to it... .And add normal text box control to the form from tools. Its just a normal text box, no back end programming is assigned to it.

You didn't finish that thought. Let me guess...
The input focus was on the TextBox and you ran a card through the scanner. The data appeared in the TextBox. Am I right so far??

WHY DIDN'T YOU SAY IT WAS CONNECTED TO THE MACHINE THROUGH THE KEYBOARD! 
Unfortunately, that's the only way your going to get it into a string. You'll have to use a TextBox, then grab the string out of the TextBox's .Text property, which returns a string.
If you don't want to use a TextBox, you COULD put together a some kind of string builder code using the keyboard events of the form, but you're card reader has to generate some kind of preamble, and possibly postamble, that your handler code can recognize so it knows the keystrokes that are coming down next are parts of the card data and not someone just typing in other parts of your form.
You might want to check into a card reader that connects to the serial port instead...

Thanks! but there isn't any keyboard event for form object. Is there anything I should do? Im using vb.net
|
|
|
|
|
Really? Then why am I looking at Form.KeyDown, Form.KeyPress, Form.KeyUp?
Set the forms KeyPreview property to True. Then, you'll have to come up with code, in the forms KeyDown event, to remember keystrokes until it sees card reader preamble, whatever that may be. For there on, it has to remember all the keystrokes until a set number of characters are read or a card reader postamble is detected.

You should have some sort of drivers for it, maybe an install located online? … Once you find some drivers, I would recommend using the Monroe OPOS Common Controls with the .Net wrapper for interfacing with it. They are pretty much the standard for windows Point of Sale applications.

Is it possible to have a double click event in a combo box that works.

What do you mean by "that works"? Theres no intuitive reason to expose a double-click event on a ComboBox. You can't double-click one of the list items because a single click will select the item and display it's text in the TextBox portion. Double-clicking in the TextBox portion should select the text of the word you double-clicked,if editing is enabled.
What do you want this double-click to do and when?

OK say the combo box is empty and you want to add a new item in the list of the combo box so you double click the box this opens a seperate form that allows you to add new item to the list which when this is done then comes back to the form is not only in the list but is the one the combo box is set to ...

Well, the ComboBox doesn't really support a DoubleClick event. Why not just put an "Add" button somewhere around the ComboBox?

in VB6 there have property clickitem in listview,but anybody can tell me how i do it using vb.net,thanx
|
|

ClickItem was an event, not a property. There's a HUGE difference...
Handle the ItemActivate event of the ListView. You can then use the SelectedItems property to find out which items are selected.

Then you will have covered everything you need to do this in the course materials. Am I right?

hi everybody
does anbody know how can i dial a number with the modem in vb .net & when the phone picked up, a sound file play for user?
tank you guys so much
|

Only if your have a modem that supports TAPI. A normal modem won't do it.
On top of that, you'll need a library that wraps a version of TAPI. You can find one on GotDotNet.com.
