Hi all

Printing problem on applications that prints directly on LPT1

I have a Visual Basic program that prints directly on LPT1. I use the method “Open LPT1 for output” in my visual basic code to print directly on LPT1. When printing on to a local printer, the program prints, but when printing on Network shared printer, the print doesn’t work. How should I redirect the printer command to the network printer?

I created a plugin that can read the length property of elements. How can I return back to the old line on which the program always points to a certain line where it cannot convert the variable and returns a null variable when I attempt to computer for the length

This is the error that I get

Uncaught TypeError: Cannot read property 'length' of undefined

Why is that when I make a <div> in html the output sometimes changes and separates too far from where I declared it. It is around 50 pixels away from the other div but I didn't add any margin or padding.

How can I fix it to make it stick to the div on top of it.

Hello Everybody,

Why is it that I keep getting this error:

Error: missing ')' in parameter list for main

I am very sure that I have closed the declaration. I re-checked everything and the missing “)” is there. But when I compile the program it keeps on returning the same error. I really need some help on this please help me with this.

Thanks.

Good day!

I have a problem with my program in turbo C.

I created a simple division program but it keeps giving this error:

I already declared it, but it still returns the same error.

I don’t know how to fix this anymore; I keep trying to change the variable but it still doesn’t work.

Hello All!

I recently got an error while programming in VB. What does it mean when I get this error?

"Ambiguous name detected"

I already used another name but with different capitalization. I used the variables phonenumber and PhoneNumber. I thought VB was not a case sensitive programming language. 

How do I fix this problem?
