Since I have no idea where these apps are installed and what your business requirements are, I have no idea!
But, if your requirement is that every app has the exact same version of the .DLL, it would probably be a bad idea to have 5 copies of it running around.

This means absolutely nothing. I have no idea what you mean by "executes the DLL by the value placed in app.config". What value?? What does it describe?

Here is an example of the code that I am referring to in my question:
strConsoleAppLocation = ConfigurationManager.AppSettings["dll_location"];
string Process_Arguments = null;
Process RPT_Process = new Process();
RPT_Process.StartInfo.FileName = strConsoleAppLocation;
Process_Arguments = " 7 " + strCUSTID + " 1";
RPT_Process.StartInfo.Arguments = Process_Arguments;
RPT_Process.Start();
RPT_Process.WaitForExit();
RPT_Process.Dispose();

I am sorry about the confusion in the terminology. Each of the 5 program calls an exe and passes parameters to the exe.
What I am suppose to do is not call an 'exe'. I am suppose to have call each 'exe' in a faster manner.
what would a faster manner be? callin a dll?

If you're talking about the length of time it takes to launch an external .EXE, then you have no choice but to move the code that's in the .EXE into the code that's launching it. This will, of course, require you to rework your code in all 5 apps. You could put the code you're using in the .EXE into a Class Library project, which compiles to a .DLL, and then you've got the code in one place which you can use in any other .EXE.

I have a question about your following statement, "You could put the code you're using in the .EXE into a Class Library project, which compiles to a .DLL, and then you've got the code in one place which you can use in any other .EXE."
If I do what you suggest above and place the code into a .DLL, that means the dll would not take parameters correct? If this is true, is there another way i can share the code between all the programs and pass the parameter values?

DLL's don't take parameters, period. They are containers for classes and modules, which contain methods, which can take parameters.
You SERISOULY need to pickup a beginners book on C# and work through it.

Question seems confusing to me.
A dll is not an executable so you are not using Process to run it.
So what is the exact form that it exists in now?
What is the exact form that it will be?
And why do you think you need to access it dynamically? Although the answer to that might be explict by the answer to the previous two questions.
But that said you can't answer how to dynamically load anything until you first decide how it will be delivered into production.

I have a C# 2008/2010 application that is currently accessed as a dll file and I would like to change the application so that the dll is accessed though as a reference. The code that calls the dll is a process and the code looks like the following:
Process theProcess = new Process();
theProcess.StartInfo = new ProcessStartInfo("filename.ext");
theProcess.StartInfo.Arguments = "args here"
theProcess.WaitForExit();
theProcess.Start();
I want to be able to pass argument values to the dll when it becomes a reference in the 5 programs that call it.
My problem is that I do not know how to pass the parameter values when the code is accessed as a reference. Thus can you tell me how to pass argument values to the application when it is accessed as a reference. Is it something in the reference call? Can you show me code and/or tell me how to acoomplish my goal?

First things first. Vocabulary.
A .DLL does not take parameters nor is it an application. A .DLL is a library of classes and methods that an application can use. Screwing up the terminology confuses people.
You always use a .DLL either by adding a reference to it in another application project, or depending on the .DLL type, can be accessed with P/Invoke (no reference required).
If referenced, you usually stick a using statement at the top to import the namespace of the classes you want to use in the .DLL. What you do after that depends on how you've written the code contained in the .DLL. Usually, you create an instance of a class with the code you want to use, then call the methods you need in that class.

Each program basically calls the dll with the paramters that is needed for the current run of the dll. The parameters change depending upon what the dll is expected in call.
Here is an example of a call that is made:
strConsoleAppLocation = ConfigurationManager.AppSettings["dll_location"];
string Process_Arguments = null;
Process RPT_Process = new Process();
RPT_Process.StartInfo.FileName = strConsoleAppLocation;
Process_Arguments = " 7 " + strCUSTID + " 1";
RPT_Process.StartInfo.Arguments = Process_Arguments;
RPT_Process.Start();
RPT_Process.WaitForExit();
RPT_Process.Dispose();
Thus do you have any suggestions on how to change the code listed above so that I can attach the dll to each program as 'project reference'?

This is such a CF...
The path returned by "dll_location" is not a "DLL" but an .EXE. You're passing a few parameters to it in the StartInfo.Arguments. You can't do that with a .DLL, so you're really not using the correct terminology. This means we're having a really hard time figuring out what talking about and what's going on.

Sorry about that! You can correct that I am going an exe. I have this question in another thread of mine so I will just close this thread.

Hi all,
I am having a problem with a databound combobox in that when I save the record (ie, end current edit,update the database and accept the changes) the combobox resets its value back to the first object in the list.
Anyone else experienced this problem before?
Thanks & Regards

What platform (i.e. web classic, web MVC, WinForms, WPF)?

Run through your code and ensure that the combobox is not reassigned datasource / values.
The combo will refresh in this case.
To avoid this, you can actually store the present value locally and then reassign to combo once save action completes.

I am running from source code, while I am calling this command "this.BindingContext[data[1, 0]].EndCurrentEdit();" it is resitting to the original value.

I have a win form application in which i have to move a picture box with arrow keys.
The problem is that when other controls like text boxes are added in the form at run time and then picture box losses its focus on pressing arrow key and picture box does not move.
please help me..

Firstly if this is VB I would put in the VB Forum[^].
Secondly you haven't shown any code snippets etc.
My first thought is that if you are using code to draw your controls rather than drag and drop from the designer can't you change the order that they are drawn?

IIRC, a PictureBox cannot have focus while in the same container with a TextBox regardless of the order of instantiation. I think it's because usually there is no need to interact with a PictureBox. It just exists to display a picture.

I don't know your control stack. But Form[^] has a boolean KeyPreview[^] property. Set it to true and handle the cursor keys outside of the picturebox. Or catch it outside and redirect it where you need it.
