you should use command line parameters and read them in Program.cs as below
static void Main()
{
string[] arguments = Environment.GetCommandLineArgs();
if (arguments.Length > 0)
{
foreach (string argument in arguments)
{
if (argument == "something")
{
call options;
}
else
{
call program;
}
}
}
}
next thing you have to create two application shortcuts in setup project and pass respective parameters to them. these are the same parameters which will read by program.cs.
based on this you can toggle start up object on you application.
Hope this helps..
pls reply if you need something else

how are charts resized in windows form the same way charts in excel. I think charts in excel convert to an image and then resized.

Why would you think that? Resizing is merely repainting the frame and its contents according to the new position and dimensions set by the user.
Use the best guess

You just need to keep some state flags to tell you whether the form can be closed or not.

It is very hard to understand the issue that you are facing using mdi windows form. Can you please rewrite your problem using proper language without any spelling errors?

The behaviour you describe is default for a modal dialog. A MDI-document is exactly that, a document-interface - not a dialog.
Use a normal form, call the ShowDialog method.
Done.

I'm testing the software. Database functions are connected using BackgroundWorker or not load any data into the control, only assign backgroundimage but at load user control on the user control the control it still blinks for 5 seconds. who have there a way to fix that for load control in the user control that does not flicker? Thank you everyone

Pause the painting[^] while updating the property and set your form to DoubleBuffered. You can post the code here if you want specific tips.

i will set property for form is DoubleBuffered = true . but it did not improve much. >.<

DoubleBuffering the form will speed up drawing "a bit". Disabling drawing as suggested will improve it "a bit" too. Without your code, I can only give these options. If you only need to assign the image to a control, then there would be not much of a "flickering", albeit the screen will show the update.

I have one form and one panel. my Panel set background image are .png. form set DoubleBuffered = true. One user control have more than 10 controls (combobox, textbox...) when User control add to this panel, it flicker
< ====== My Code> http://www.mediafire.com/?1mgh5qjcly1auq2[^]
UC 1 : have DoubleBuffered = true.
But I don't want form flickered when load. I want form load the same when form don't set background image.

Then read the link provided to stop it drawing while running the InitializeComponents-method. How long does it take to show that form? Contains many controls?
--edit;
The idea would be for you to post the relevant code, surrounded with pre-tags, not a binary package.

That's what I'm trying. Let's try it another way; copy the method below (comes from here[^])
public static class SuspendUpdate
{
private const int WM_SETREDRAW = 0x000B;
public static void Suspend(Control control)
{
Message msgSuspendUpdate = Message.Create(control.Handle, WM_SETREDRAW, IntPtr.Zero,
IntPtr.Zero);
NativeWindow window = NativeWindow.FromHandle(control.Handle);
window.DefWndProc(ref msgSuspendUpdate);
}
public static void Resume(Control control)
{
IntPtr wparam = new IntPtr(1);
Message msgResumeUpdate = Message.Create(control.Handle, WM_SETREDRAW, wparam,
IntPtr.Zero);
NativeWindow window = NativeWindow.FromHandle(control.Handle);
window.DefWndProc(ref msgResumeUpdate);
control.Invalidate();
}
}
Call it in the InitializeComponents, or whereever you put the image in the control.

Please do so - wrote the example in a few spare moments, based on a new project;
using System;
using System.Windows.Forms;
using System.Threading;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
SuspendUpdate.Suspend(this);
InitializeComponent();
SuspendUpdate.Resume(this);
}
public void button1_Click(object sender, EventArgs e)
{
SuspendUpdate.Suspend(this.pictureBox1);
this.pictureBox1.Image =
SuspendUpdate.Resume(this.pictureBox1);
}
}
public static class SuspendUpdate
{
const int WM_SETREDRAW = 0x000B;
public static void Suspend(Control control)
{
Message msgSuspendUpdate = Message.Create(
control.Handle, WM_SETREDRAW, IntPtr.Zero, IntPtr.Zero);
NativeWindow window = NativeWindow.FromHandle(control.Handle);
window.DefWndProc(ref msgSuspendUpdate);
}
public static void Resume(Control control)
{
IntPtr wparam = new IntPtr(1);
Message msgResumeUpdate = Message.Create(
control.Handle, WM_SETREDRAW, wparam, IntPtr.Zero);
NativeWindow window = NativeWindow.FromHandle(control.Handle);
window.DefWndProc(ref msgResumeUpdate);
control.Invalidate();
}
}
}Here we add in some help-routines in a new class; they should be in a separate file. Before updating something, call "Suspend" to stop the drawing temporarily and "Resume" to active it again. It'll speed up things on the UI-thread if it doesn't have to paint every change. I've also surrounded the "InitializeComponents" routine with those calls, to speed up the load-time. Again, it helps "a bit", it's not a miracle-worker. If your image is very large (>5 Mb), then it might be wiser to change the image.Lương Tuấn Anh wrote: Do you have Yahoo or mail ?

Only one control can be suspended at a time; remove the suspend-methods in the UserControls and it should work

In a C# 2008/2010 desktop application, I need to be able to allow users the ability
to select a file they need to work with. There needs to be a default directory path. However I need to be able to allow users the ability to select files from whatever directory path they have access to.
Thus can you tell me. show me code, and/or point me to a url I can use as a reference to accomplish my goal?

use OpenFileDialog Control. this will allow you to choose any file.
You can get file name using OpenFileDialog.FileName
|
|
|
|

OpenFileDialog control seems to be the only option for you as it can allow users to choose any file from whatever directory path they want to access.
