Hello,
we r doing project using USB scanner. when we scan a barcode i need Serial number of scanner to be detected with data... Now i am only able to read Data and even i got serial number of scanner when we connect it to system. But i need this scanner serial number to be fetched when i scan any barcode...i.e from which scanner barcode was read... is there any dll to fetch serial number at run time..

Plz can any one Help ... its very urgent requirement.....

You need the serial number that's printed on the hand scanner at the moment that they scan a barcode ? What does the manual that came with the bar code reader say ? It's pretty obvious that you need to read the documentation and look into the SDK that came with your barcode reader.

i have gone through the mannual they have provided but there is no option for that, and one thing i noticed in CD that there is no POS.exe provided for that. Only configuration settings are available....

i m developing an application in which i need that the system commands for ctrl+a ctrl+c, ctrl+v are appiled automatically without pressing the keys from keyboard....pls anybody help me.. Confused | :confused:

You can do the copy and paste in code, if you mean they are applied within your app. What does CTRL-A do, select all ? you can do that, too. What sort of controls do you want to do this to, just textboxes ? What do you mean by 'automatically' ?

How can I draw control or image on screen instead of form?
Something likes office assistant character.

By getting ahold of the Graphics object that represents the desktop. In C++, that was easy, not sure if it's exposed in C# without interop.

Hi everyone,

How to pass command line arguments to a .net exe from another .net application?

As it's a command line arguement you're asking about, it's passed when the app is executed. So, use Process.Start to start the app, and specify your command line arguments.

Of course, he asked to pass it from another .NET app, not from the console.

Yes, that we can.

But I have to get the values from a windows application and that value has to be passed to the exe.

For this I tried to use Arguments of ProcessStartInfo class but through that it is possible to pass only one argument. But my requirement is to pass more that one arguments.

Process.Start ( as I said ) will take as many arguments as you like as a single string parameter.

thanks

Thank you.

So the arguments has to be separated by means of a separator and then in the receiving end we have to parse it based on the separator.

But we can't pass as an array.

Is it Right?

If yes then what is the purpose of the array specification in the main method.

maybe you can use this:

Process exe = new Process();
exe.StartInfo.FileName = "execute File path";
exe.StartInfo.Arguments = "List your args";
exe.Start();

I have m working on winform application.
In one panel i have 2 datagridview( which are created dynamicaly and can move) i have done this part.

In DataGridView i m showing table column name.

Now when user do drag drop operation i.e drag ny row of first datagridview to second, a line should come between them ( to show link between them).

How to create a line in c# and when user move datagridview by mouse, this line should move.

I didn't find out any line control in visual studio 2005.

Hope you understand what i m asking for.

Thanks lot.

you should use graphic class.
some code like this:

Graphic gd=this.createGraphice();
gd.drawline(Pens.black,new Point(10,10),new Point(100,100));

so,gd class draw line from 10,10 to 100,100 on the form.if u like to draw it on Panel u should create your Graphic class instance from Panel.

it means u should write:

Graphic gd=panel.createGraphic();

NEVER call CreateGraphics. Unless you want a temporary line that will disappear when the form is invalidated.

NEVER call CreateGraphics

what should i do if i want to draw something on a control?!

Handle it's paint event. If you must call CreateGraphics, you need to do it inside a paint event, otherwise, your painting is going to disappear the moment your control is obscured.

Thanks Christian Graus and all.
I m able to draw line but now i to increase or decrease the length of line by mouse.
I don't have any reference to that line.
How to do this.

Hope you understand what i mean.

Thanks lot.

The graphics class has a DrawLine method. If you handle the paint event of the control you want to draw on, you'll be responsible for drawing all of it, but you will be passed a graphics object to use. Calling CreateGraphics creates a temporary object, if your window is hidden and shown again, what you drew will be lost.
