Sorry to disappoint you, but the Control class does not support a transparant backgound. And as the Textbox control derives from it...

Could NASA(a rather big compagny IMO) not provide some training courses for his employees? To much cutting on the budget is never good.

google is your friend, [example](http://www.apress.com/9781430242604)

Use a `for` loop with elements of line 12 to line 32 of your code.

Please loosen the caps lock key on your keyboard. YOU ARE HURTING MY EARS, IF YOU KEEP SHOUTING LIKE THAT!

Hi Florlan, welcome to Daniweb. :) Your question is rather vague. Please post a question that is more specific.

What exactly do you mean by number of pages? Number of worksheets in a workbook? Here is a [link](http://vb.net-informations.com/excel-2007/vb.net_excel_2007_open_file.htm) to get you started.

I watched your files and I think the solution to your problem may be found [here](https://social.msdn.microsoft.com/Forums/vstudio/en-US/a494abb8-3561-4ebe-9eb0-6f644a679862/visual-studio-2010-professional-how-to-add-include-directory-for-all-projects?forum=vcgeneral). This is where to look: 

This very much resembles a [snippet](http://www.daniweb.com/software-development/csharp/code/217194/data-encryption-in-c) I once wrote in C#! Good work on your part here! Some tips: 1)I should make the password with unique chars, it would diminish the detection of double chars like the oo in "book". 2) The longer the password, the better. You could manipulate …

Do you mean the [floor method](https://msdn.microsoft.com/en-us/library/e0b5f0xb(v=vs.110).aspx) from the Math class? EDIT: Almost forgot:use this as a for loop: int sq = Math.Round(Math.Sqrt(n)); for (c = 2; c <= sq; c++) etc.

I found [this yuo tube](https://www.youtube.com/watch?v=twlo21D9LY0) to be a very good guide. Look on wikipedia for pseudocode. Btw. did you know your prime algoritm can be made 2 times faster, but perhaps you don't need that?

Just leave the zeros out. Do you know any 4 digit number, when summing up the rest of his digits is equal to zero, the 1000th digit? In fact 0089 for example is not a number. 89 is. I would set my lower limit to 1000 and upper limit to …

Earth IS in fact falling to the sun. But its orbital speed is such that it keeps spinning around. Speed too slow or zero, we will fall into the sun eventually, speed too big we will leave the solar system. The closer the planet to the sun, the greater its …

Question 1) I think this can be solved with a macro. Question 2) Did you look in the Options--> Languages section? You might also find something on sorting on google. Hope it helps a bit.

Do you have any specific question with a difficulty while doing this homework?

Are you going to allow more than one **.** input? How about backspace and left right keys?

I guess your google skills must be updated: [one of my first hits](http://www.vb-decompiler.org/)

Local variables are declared in a procedure, global vaiables outside.

Only $250/h ? I would charge at least $1000 USD for the whole project and probably finish it in one hour. Which would give me 3 hours of relaxation.

Well if `X % 3` is zero then you know X is divisible by 3.

System.IO.Stream**Writer** will never read anything from a file I guess ...

At a low level they are sometimes useful I guess. I remember I used them in the previous century when programming in BASIC. With todays modern languages, there is absolutely no need you should use them, unless you like to write "spagetti" code with all the not needed problems that …

I wanted to upload an excel file with one of my threads, but it is refused. Do I have to zip it first and if so, why?

On line 22 of your code I should definitly try `int mul=1` instead of `int mul=0`

What have you already come up with? Please post your code

Why should try-catch be an overkill? It is designed for situations like that.

A List<T> in c# is the same as a vector<T> in C++. cout would become Console.Write or WriteLine in C#.

Why are you converting `Solde` and `Nip` to double on line 7 and 8? They are already of type double. Just pass them to the constructor on line 9. On line 15 did you try `resultC += client[i].Full;`?

Consider making a [List](http://msdn.microsoft.com/en-us/library/6sh2ey19(v=vs.110).aspx) of conference classes out of the text file. Should be easy sortable any way you want.

Pakistan is a big country to display 10 times in a for loop. What is the code you already have and with what part do you have problems?

Hi doris welcome to Daniweb. :) Take a pencil and a paper. Write two arbitrary large numbers on it and notice what you do when you add them together. For your program: Drop those numbers in two arrays. Start by doing the same as on paper. Take the last digits …

The main error message starts on line 4 : Cross-thread operation not valid: Control 'progressBar1' accessed from a thread 5.other than the thread it was created on. TRy to create the progresbar in the same thread

Can you explain why you find the books proposed by hericles silly?

TRy out the Sustring method : [link](http://www.dotnetperls.com/substring-vbnet)

Do you know how to write an "Hello world." program in C++? If yes, then just change the hello world in what Moschops wrote. It is an answer to your question! Try it and see!

Your asteriks are uneven. You could center a number of asteriks in a string of blanks(if the chars are equiditant, but I guess that is the case here) and cout the string.

Why not use Textbox.Clear instead of ResetText?

What about 45°30'10''? Angles don't always come in whole parts.

Indeed, your idea does not work. At bitlevel, PrescriptionOnly = '01', InstructionOnly ='10' and Both = '11' Make Both equal to 4. Now you have 3 bits(flags) to work with.

You got to have a DataSource and a BindingSource. See [this article](http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.datasource(v=vs.110).aspx).

Happy new year to everybody! :) In case you invite some folks, [this](http://www.instructables.com/id/Christmas-Tree-Napkin-Fold/) might be a tip.

Is it the smoke that irritates you, or rather the odor "perfume"?

Make [B]r [/B]and [B]target [/B]fields of your form. Perhaps you could have a button New Number with the lines 3 and 4 of your last code in it? Of course remove lines 7 and 8 from your buttonEnter handler.

You should first get a line from your textfile and split it in separate strings and then feed those strings to your strVec variable.

Looking on the web for how to do it. Found several solutions: serialisation, XML etc. Cannot decide which to use. My List class contains a string, some booleans and two other Lists. Awaiting some opinions that will be accepted with great gratitude. :)

To accomplish a goal you have to do some efforts.

[QUOTE]while (revstack.Peek().ToString() == "+" || revstack.Peek().ToString() == "-" || revstack.Peek().ToString() == "*" || revstack.Peek().ToString() == "/") stack.Push([COLOR="Red"]revstack.Pop()[/COLOR]);[/QUOTE] I am still with your first code: if revstack pops it can find empty and you get an error. You cannot pop anything from an empty stack.

What are you finding "very difficult"?
