Hi experts,
I have an urgent issue that need to be fixed ASAP. Anyone of you know how to open cash drawer using C#.net 2.0. I'm using Epson receipt printer TM-U220 which is connecting to the cash drawer. The printer is using LPT port.

I found a few resources Eg http://support.microsoft.com/kb/322091 , but still could not make the cash drawer open.

Appreciated if anyone of you could guide and provide me some information regarding this.

Thanking you in advance.

Which button did the mouse click

I have several mouse buttons that on a mouse click they call the same function, but I need to know which button was pressed.

Is there are way to determine this?

private: System::Void btnTmOut_Click(System::Object^  sender, System::EventArgs^  e) <br />
{<br />
...Bunch of code...<br />
if(btn1)<br />
  x = 0x0001;<br />
else if(btn2)<br />
  x = 0x0001;<br />
...<br />
else if(btn8)<br />
  x = 0x0008;<br />
...Bunch of code...<br />
}

Thanks

The sender parameter should hold a reference to the button that caused the event to be raised. You should cast it back to a Button before using it. To follow the psuedocode you have in your question, you would want to make sure each button has a distinguishing name and test the Name property. You could also use the Tag property, but you will still end up doing string comparisons.

What is the reason you have all of the buttons going through the same event handler? If each button does something different you are better off sending them to different event handlers. If there is common code (like logging) that needs to occur, refactor that into a separate method and have each event handler call that method at the appropriate time.

Thanks it works great. Here is my final code. This greatly reduces the variables that have to be shared in the class.

private: System::Void btnTmOut_Click(System::Object^  sender, System::EventArgs^  e) <br />
{<br />
...<br />
Button          ^btnLocalOnly = (Button^)sender;<br />
...<br />
  if(btnLocalOnly->Name == this->btnTmOut1->Name)<br />
    x = IO_1;<br />
  else if(btnLocalOnly->Name == this->btnTmOut2->Name)<br />
    x = IO_2;<br />
  else if(btnLocalOnly->Name == this->btnTmOut3->Name)<br />
    x = IO_3;<br />
  else if(btnLocalOnly->Name == this->btnTmOut4->Name)<br />
    x = IO_4;<br />
  else if(btnLocalOnly->Name == this->btnTmOut5->Name)<br />
    x = IO_5;<br />
  else if(btnLocalOnly->Name == this->btnTmOut6->Name)<br />
    x = IO_6;<br />
  else if(btnLocalOnly->Name == this->btnTmOut7->Name)<br />
    x = IO_7;<br />
  else if(btnLocalOnly->Name == this->btnTmOut8->Name)<br />
    x = IO_8;<br />
  else<br />
  {<br />
   //Error<br />
   }<br />

User-ordered list (C#)

Hi,

I want the user to order a list of items. What I had in mind was a control similar to a ListBox, where the user can click-and-drag items into the order they need. This is a fairly common operation, but I was unable to find a predefined control doing this. Any help?

thanks..

Theres no control that will do this by default that I can think of.

This is an article on how to modify a ListView to allow row reordering.

Create a property on this form that exposes the user no. The access that property from the other form before closing this one. You only hide the login form when done, and close or dispose it after reading the property.

If you want to use valid login name on another form after user authentication the you can create a public property on your another form and fill it with the value by accessing it before opening that form.

Ex:--> if you are on "login.cs" and want to open "Admin.cs" then code for admin will have a public property say "UserNo"

Private int userNo;

Public property int UserNo
{
get { return userNo;}
set { userNo = value;}
}

Now on login.cs after user validation

Admin admin = new Admin() (( This depends opn your architecture))
admin.UserNo = login;
admin.ShowDialog();

This way the user no will be available as per code optimization also.

I have a windows form in C# with some text boxes and a botton control.
I wanted a code piece to guide me to feed an excel sheet from a text box over a button click. To elaborate it, the contents of a text box should go to a particular cell of the Excel work sheet on button click.

A reference to an article that may solve the problem will also do. Smile | :)

This piece of code should do for you :

private void startButton_MouseHover(object sender, System.EventArgs e)<br />
		{<br />
			startButton.BackColor = Color.Yellow;<br />
			ToolTip toolTip = new ToolTip();<br />
			toolTip.ShowAlways = true;<br />
			toolTip.SetToolTip(startButton, "Whatever Message...");<br />
			<br />
		}

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
