what does it mean?thanks

It means the bool variable takes memory of 1 byte.You should take some basic book of fundamentals and c#.

Hi,
I have a application which i want to run and operated programmatically using C#. Using the System.Diagnostics.Process.Start() i can run the .exe. But i wish to operate or click on the various buttons on the UI of the program.
For instance i can run Calculator using System.Diagnostics.Process.Start(C:\Documents and Settings\All Users\Start Menu\Programs\Accessories\Calculator). Now the Calculator application is up and running how can i operate on it programmatically. Is it possible to press the various buttons of the Calculator like "+", "-", "1" , "2" etc, programmatically ??

Thanks in advance

You can send the appropriate messages to the Calculator application.

Can you be more specific to your Qs/requirement?

although at runtime time you can create datatable using DataTable class.Use google/msdn

Why don't you use List?Use list of Datatable.Here you don't need to worry about the size.Create datatable at runtime and add to the list.Whenever you need you iterate the list and use them accordingly.

That's OK.But if I don't put the value in configuration then how would i know the count of datatables ???

Re: How to dynamically create many datatables in c#.net

Brij1-Jan-09 23:58

You can get the count from the list itself.You can store it some session variable (if user specific) or application varaiable(if application specific) for any other use.

One thing How are you getting the count of the table.Is it coming at runtime?Can you be more specific to requirement?

How would i do interprocess communication ??

fulbright1-Jan-09 19:47

1-Jan-09 19:47

A windows service is supposed to launch an application, passing some arguments to the executable. I am trying to do this using CreateProcessWithLogonW(string principal,
string authority,
string password,
LogonFlags logonFlags,
string appName,
string cmdLine,
CreationFlags creationFlags,
IntPtr environmentBlock,
string currentDirectory,
ref StartupInfo startupInfo,
out ProcessInfo processInfo) API function.

I set the parameter "cmdLine" for passing string to the executable. The following code doesn't get me anything ...

static void Main(string[] args)
{
// that doesn't give any value
string acrossprocessvalue = args[0];
//neither the following lines
string test = Process.GetCurrentProcess().StartInfo.Arguments;

}

any help ...

Process.Start will do it. Process class provides options to supply arguments too.

Thanks for the answer ... I started with Process.Start() actually but that wasn't fulfilling the requirements. e.g, The windows service is running under the "Network Service" user, a less privileged user,that wont be having the rights to display application on desktop, etc. So for such security tunnings I had to use CreateProcessWithLogonW() API function.

"cmdLine" argument that i'm trying to pass to CreateProcessWithLogonW() is a string basically but does it have some specific format ? I'm simple passing the value as
cmdLine = "testargument";
Is it OK ????

Pass whatever you want, as long as the spawned app understands it.

Hi All ,

public abstract class ValidationBase

public abstract class ValidationCollectionBase<T> : Collection<T> where T : ValidationBase

T is the type and where is a constraint which will ensure T will be a type of ValidationBase. Read about generics[^]

Regarding reading and Writing xmlfile after deployment

hello froum

I am writing the elements to xml file on runtime,and also using them. It is working properly.

XmlDocument xmlDoc = new XmlDocument();            
string path = AppDomain.CurrentDomain.BaseDirectory + @"\XMLFind.xml";            
xmlDoc.Load(path);            
XmlNodeList xmlNS = xmlDoc.GetElementsByTagName("testword");

The xml file is in the bin folder.

but the problem is after creating setup the xml file is visible to every body so it can be deleted accidently.

If the xml file is placed in the project then while using the output (after creating its setup) it gives the runtime error

Could not find the C:\Program Files\hts\SetupFinal\XMLFind.xml.

can anybody help me...

Regards

Rahul Adya

There is no way to secure it. Just check the file existence before you read it and tell user if it is not available.
