Obviously they will, when you visit a website that uses them. However, your questions was about deleting index.dat, which has nothing to do with the cookies.

You can use windows API to delete all the cookies.
The functions below are useful:
FindFirstUrlCacheEntryEx, FindNextUrlCacheEntryEx, DeleteUrlCacheEntry.
They are defined in wininet.dll.

Ive now seen that when the process class is used as an instance there is a WaitForExit() method

but now i'm getting an error on myProcess.Start("ring.exe"); " System.Diagnostics.Process.Start(string)' cannot be accessed with an instance reference; qualify it with a type name instead "

here is the code

Process myProcess = new Process();
myProcess.WaitForExit();
myProcess.Start("ring.exe");

thanx

try use the following

//Wait for window to finish loading.
process1.WaitForInputIdle();
//Wait for the process to exit or time out.
process1.WaitForExit(5000);

hmm... it seems WaitForInputIdle method only works with processes that have a user interface...

Alternatively i think u can do that using threading..i'm not sure

Capture Batch-File Data

I'm wondering if anyone could help me in this one... I'm attempting to execute a simple Batch-File, and capture the output.

So far, I have something along the lines of:

System.Diagnostics.Process tyroTest = new System.Diagnostics.Process();
batchTest.StartInfo.FileName = Application.StartupPath + @"\myFile.bat";
//batchTest.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
//string batchText = batchTest.StStandardOutput.ReadToEnd();
batchTest.Start();
StreamReader sr = batchTest.StandardOutput;
MessageBox.Show(sr.ReadLine());

but am carrying on recieving errors like:

StandardOut has not been redirected or the process hasn't started yet.

As you see by the commented-out code, I've tried multiple variations...

Any hints, anyone?

Smile | :)

You need to add these lines. Why don't you read documentation?

batchTest.StartInfo.UseShellExecute = false;
batchTest.StartInfo.RedirectStandardOutput=true;

Try adding batchTest.StartInfo.RedirectStandardOutput = true; before you start the process.

hey there

would you mind showing me how you got it working? im trying the same thing now and i get the same error

here is my code

Process myProcess = new Process();

myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardOutput = true;

myProcess = Process.Start("ring.exe"); // ring.exe is a console app that just writes "ringer rang" to the console

Console.WriteLine("Started 1st process --> Waiting... ");
myProcess.WaitForExit();

StreamReader sr = myProcess.StandardOutput;
Console.WriteLine("Finnished 1st process ---> output:");
Console.WriteLine(sr.ReadToEnd());

Hi All,

I am using VS03 + c# + MS ACESS databse.
In my application i am creating a CommonConnection.cs class where i store the path of the database.
From this class i am fetching the connection all the time.
But now i want to use app.config file for setting the path of the datbase.
Please tell me how can i store the path of databse in app.config file and as well as how can i fetch the value of databse path to any form.I also want to save datbase password in app.config.

Here is my code for store the path of database.
public OleDbConnection connection()
{
OleDbConnection aConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\Data\\Test.mdb;Persist Security Info=True;Jet OLEDBatabase Password=san7481");
return aConnection;

}

here i am fetching the value of connectionstring in form ,from class file.
CommonConnection objCI = new CommonConnection();
private void frmIrrigationTreeSpecifications_Load(object sender, System.EventArgs e)

{
OleDbConnection aConnection = objCI.connection();

}

Thanks in advance.

string connection= System.Configuration.ConfigurationManager.AppSettings.Get("ConnectionString");

I recommend reading the article I link to in my sig, you could have easily found this info with a google search.

C# simple windows form taking alot of RAM

Hello!

I am looking for some suggestions/tips for the following issue:

I have a C# Windows application having 1 form. In that form i have 12 text-boxes, 2 progress-bars, 5 buttons, status strip and 5 group-boxes.....as displayed in task manager, it is taking more than 25 MB of RAM! I haven't placed any code yet, any recommendation/tip/suggestion for the issue will be appreciated.

BTW, any idea how much RAM should it be taking?

Regards,

Adeel

Do rate the reply, if it helps or even if it doesnot, because it helps the members to know, what solved the issue. Thanks.

25 MB seems fine to me. Remember, there's a residual amount of RAM before you start adding stuff. A second form won't make it 50 MB.

I agree with Christian on this one.

It seems the simplest Windows App takes +- 20MB RAM, and then any (Not-too intensive) code takes up insignificantly more.

Create a "Hello World!" windows form to see what I mean.

I'm not exactly sure WHY, but that's the way it works Smile | :)

We should learn from C++, where A "Hello World!" Form-Based app takes like 200k RAM Wink | ;)

Looks like you're using a component that is not registered or not licensed on the form
