What the hell was in your original message that this pile of crud is what you modified it to. Don't use textspeak, and don't try to get people in the forums to do your homework for you - at least you'll have the pride when you fail your course, you'll fail on your own.

hush now, we must never find the master plan of 1337 #@X0r'5 to come to code project so they can get us to write application their tools which pwned the world!

It does make me wonder if someone did send evil codz to one of those "plz send teh codz" what would happen to them when their professor ran it :/

Hi,

I've strange requirement to meet, please some one help out.

I've two EXE one for uploading data into DB and another is Searching DB. But i can search the DB by using the Object which is created by first EXE. Is there any possibility that second EXE should be able to access the Object which has been created by another EXE.

Or is there any other way to resolve it.

Thanks in advance.

You can share objects between processes by using .NET remoting and MarshalByRef objects. Look up some remoting examples on the web.

You have to make third application much probably a class library, the purpose of that class library is to read,write in db

use that class library in your both exe's

What does a method return type followed by a question mark (?) indicate?

I just saw this in code that I am maintaining and I have never seen this before.

Try selecting between 132 and 135, then divide by 100.0 ( dividing by 100 will give you an int, not a float )

Use the NextDouble method instead of the Next method. The Next method returns a number between 0 and int.MaxValue.

The range (difference between lowest and highest) is not 1.35, it's 0.03, so that's what you should multiply the random number by.

double n = 1.32 + r.NextDouble() * 0.03;

Despite everything, the person most likely to be fooling you next is yourself.

Hello,

First of all thank you for this magnificent web site.

I am new to C# and trying some basics on my own.
As you may know if you try to define a path variable as a string in C# you must use "\\" to indicate backslashes:

i.e.:
string filePath = "C:\\Windows\\Temp\\file.txt";

But what if I should received the path information as a parameter to my main() method?

I have tested it many times in simple applications but I could not open a SaveFileDialog in the specified directory. Please consider the following examples that sets SaveFileDialog.InitialDirectory property.
The operation of the application is simple, just display a SaveFileDialog pointing to the location passed to the Form1:

This one works pretty fine:

///

/// The main entry point for the application.
///

[STAThread]
static void Main()
{
string initialDirectory = "C:\\Windows\\Temp";
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1(initialDirectory ));
}

and Form1 class has the following codes inside:

public partial class Form1 : Form
{
private string initialDirectory;
public Form1(string initialDirectory)
{
this.initialDirectory = initialDirectory;
InitializeComponent();
InitializeSvFDlg();

}

private void InitializeSvFDlg()
{
this.saveFileDialog1.InitialDirectory = this.initialDirectory;
this.saveFileDialog1.ShowDialog();
}
}

--------------------------------------------------------------

I observed that SaveFileDialog does not show the passed directory when I use the following method in main() and start the program from Command Prompt with SvFileDlgShow.exe "C:\\Windows\\Temp" command:

///

/// The main entry point for the application.
///

[STAThread]
static void Main(string[] args)
{
string initialDirectory = args[0];
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1(initialDirectory));
}

Form1 class is the same.

--------------------------------------------

But the executable works fine if I use SvFileDlgShow.exe "C:\Windows\Temp" as the start-up command.
Is this the intended operation?

Any help is appreciated.

Erasing Lines with drawing tool

The reason you use \\ is because \ is used to escape characters, for example, \" is how you put a quote. You have another option:

@"c:\Program Files\Atalasoft\DotImage 6.0"

will work fine, the @ means that \ means \. The \\ actually is turned into \ in your final string ( although the debugger will show \\ ). So, if you pass a parameter, it should be a single \, because \\ is in fact how you tell the compiler to emit a single \, if you've not put @ at the front of the string.

Ive been developing an interface that updates a schematic with dimension lines and re draws different parts based on selection from radio buttons.

The problem is when I go to delete part of the drawing and draw a different part. The only method I have for erasing is to paint over the drawing with a white pen, but now when I mouse over the control the Diagram flickers remains of the painted over drawings.

Ive read some articles about double buffering, but was hoping there was something else I could do without a major setback.

Your design is incorrect. You drawn parts should be objects that you can manage.

This is a MAJOR setback. What you need to do, is collect details of lines to draw, and draw them on the screen in the paint event, not ever drawing them on the image. Then you can just undo any line you want.

Yea I really didnt know anything about painting when I started so went about this in the completely wrong way. You say collect details of lines to draw and put them all into 1 paint event. Right now I have dozens of paint events that are called. The diagram has to update in real time every time the useer changes a textbox or radio button so it had to draw a lot.
