You can't add an executable as a resource and simply have another application "run" it as though it was part of the "host" application. What you want is a library (dll) not an executable. This means you will need to figure out what parts of the VB application you would like to re-use and re-create those pieces as classes or user-controls in a dynamic link library. Once you have those components in a library, you can add a reference to that assembly and start using the components.

if you have two .NET apps you can turn one (or both) of them into a DLL, and make
the remaining one (or a new one) the master controlling the other (or both).
The one (or two) that demotes to a DLL looses its static main function (C#) or the
VB equivalent, so it basically becomes a class library; to call it, instantiate
its main form and show it (as the static main does in a regular C# Windows app).
You must do it with a single version of .NET (hence the same Visual Studio);
having a non-Express edition probably makes it much easier, since now you can load
all relevant projects in a single IDE.
With VS2008VB Express + VS2008CS Express, you should also be able to do it, have one
create the DLL, then add that to the references of the other.

Ashley Staggs wrote: how do i change the vb project into a dll
when you create a new project you are given a choice between many possibilities, one
of them is a "class library" or something like that. So create one of those, copy/paste
almost all your code in there, and just leave an almost empty program in your original exe
project.

if the dll basically holds a Form derivative, you instantiate and show it.

I dont know how to control ports of serial of my computer with programming.
I want to know the code of it and exactly how to tell the computer that i want it to turn on the outputs of the ports.
I am very thankful if you give me the code in c# and tell me how to wark with it.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hi,
you want the SerialPort class (available since .NET 2.0)
open the port, then write data to operate the TxD line, and/or use the appropriate
properties (such as DtrEnable) to control the control lines.
Warning: turn off hardware handshaking if you want to be in charge of some of those lines!
Advice: read all the MSDN pages on SerialPort, AND search CodeProject for SerialPort articles
and read some of those as well.

Hi,
Can anyone tell me how the normal parameter in C# are passed? is it by Ref? or just value?
Cuz i'm getting a bit problem with my code. I have this code that calculates statistics and for that i need to sort() my array. but this method also (somehow) is being applied to the array that i passed into the function...
for i.e.
<br />
private int iAnswer(ArrayList arData)<br />
{<br />
arData.Sort();<br />
}<br />
<br />
text1.Text = iAnswer(arNum).ToString();<br />
So what i'm trying to say is that when i do arData.Sort() it also sorts arNum somehow??!!

C# parameters are passed by value. But there are some sutle things here. C# has reference-base objects and value-based objects. For the reference-based object, you can think it as an object holding an address. So, when you pass them to a function, only the address will be copied. For your code, the last line passed arNum to iAnswer. iAnswer copy the address holded by arNum to it's own parameter, arData. When you sort arData, the real object that is pointed by arData and arNum will be changed.

Bert delaVega wrote: The ArrayList is a object, so it's allocated to the heap (a reference type). So in your case it is by ref.
That is not correct. It's a reference that is passed as a parameter, but it's not passed by reference. The reference itself is copied and sent as a parameter, it's not a reference to the reference that is sent as a parameter.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
if you are familiar with older languages such as C, it is very similar:
1. simple things (int, double) get copied (pass by value);
2. for complex things (strings, class instances) a pointer is passed (so there is no object
copied, it is the same object you get). Whether you call this by value or by ref however
is a bit confusing (you can optionally add a ref keyword to increase the level of indirection
by one)

It means that you've declared parcalar in the wrong place. Move the declaration to before the while and it will be visible. So, you get
string[] pacalar = null; However, you do know that you are only going to write one line to the file don't you?

"However, you do know that you are only going to write one line to the file don't you? "
mr.pete as your told it is writed one line to the file but i want to as a column by reading all line. please help me.
sample:
1456
4596
122.2
145.4

Move the declaration of the streamwriter before the while loop, and write to it when you need to then close it afterwards.

firstly thanks for help you.

You've decalred the variable parcalar twice, although in different scopes. The problem is the compiler would have no way of knowing to which you were refering so it will give you that compile time error.
Remove the 'string[]' from the second declaration.
Also try using pre tags with code to preserve indenting. You'll get more help.
I'm largely language agnostic

Hi all,
I am looping through a series of directories moving files fom one place to another, this i haven't got a problem with.
My query finds all files and moves them without a problem with the exception of all the .zip files.
This has me stumped.
I can get the FileInfo for the zip files and response.write the name onto the page, so I know they're being found, however the File.Copy isn't moving them.
I am running the query under an if (FileName.Extension.toString() == ".zip")
which works for writing the name, just not copying the files?
Please help if you can, many thanks in advance
Mark
