Member 10404865 wrote: How to print multiple panels with database
What panels? If you are just wanting to print your data in columns then you need to lay it out within your code by specifying the position of your data on the physical page. However, your question is not very clear, please provide more detail.

Hi,
It should be like mailing address in panel.The printing should be made tabular columns(Two columns and four rows per page).Still confused it should be like id card badge.

Fine, you have told us your requirements, but not what your problem is. Please explain with proper technical detail exactly what your code is doing and why it does not work.

Hello
I want to change mouse cursor for all windows how I can do it by use API or other method.
thanks in advance.
|
|
|
|
|
|
y should use
[DllImport("user32.dll")]
static extern bool SetSystemCursor(IntPtr hcur, uint id);
[DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
public static extern IntPtr GetCursor();
[DllImport("User32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr CopyIcon(IntPtr hInstance);
to change system cursor .
my cursor style is an image
get image
Bitmap image = new Bitmap(asm.GetManifestResourceStream(SIECURSORBusyImageResourseName));
sIECURSORBusyMouseCursor = image.GetHicon();
IntPtr intPtr = default(IntPtr);
SetSystemCursor(intPtr , OCR_NORMAL);
then you can change the cursor, i have test it in window 8。

|

That's a nice thought and all, but each application controls the mouse cursor when the mouse is over their windows. You can try to change it, but don't expect that change to stick or work in every situation.
You can change the cursor at the system level, basically, the "default" cursor shape, but don't expect it to stay that way when the mouse moves over an application window.

Hi I am try to get rid of an error caused by a null when I run the app it stops at:
HERE---> if (mySettings.Contains("setUserName"))<---HERE
Error Message "An unhandled exception of type 'System.NullReferenceException' occurred in Password.dll"
it doesnt show any errors prior to the button click, app loads up fine.
code below
using System.IO.IsolatedStorage;
namespace Password
{
public partial class MainPage : PhoneApplicationPage
{
IsolatedStorageSettings mySettings;
public void Settings()
{
InitializeComponent();
mySettings = IsolatedStorageSettings.ApplicationSettings;
if (mySettings.Contains("setUserName"))
txtUserName.Text = mySettings["setUserName"].ToString();
if (mySettings.Contains("setPassword"))
txtPassword.Password = mySettings["setPassword"].ToString();
}
public MainPage()
{
InitializeComponent();
}
private void btnAdd_Click(object sender, RoutedEventArgs e)
{
if (txtUserName.Text != "" && txtPassword.Password != "")
{
if (txtPassword.Password == txtPasswordConfirm.Password)
{
if (mySettings.Contains("setUserName"))
{
mySettings["setUserName"] = txtUserName.Text;
}
else
mySettings.Add("setUserName", txtUserName.Text);
if (mySettings.Contains("setPassword"))
{
mySettings["setPassword"] = txtPassword.Password;
}
else
mySettings.Add("setPassword", txtPassword.Password);
mySettings.Save();
MessageBox.Show("Settings Saved Successfully");
}
else
MessageBox.Show("Passwords are not matching");
}
}
private void btnCancel_Click(object sender, RoutedEventArgs e)
{
NavigationService.GoBack();
}
}}

IsolatedStorageSettings.ApplicationSettings;
seems to return null for some reason. Why? I have no idea, best guess is that you haven't it initialized anywhere.

Marco has clearly identified the most probable source of your 'null error.
Any time you have an error like this, it's a good idea to set a break-point before the error occurs, and then single-step through the code, inspecting the value of variables, the values returned by methods, etc.
"What Turing gave us for the first time (and without Turing you just couldn't do any of this) is he gave us a way of thinking about and taking seriously and thinking in a disciplined way about phenomena that have, as I like to say, trillions of moving parts.
Until the late 20th century, nobody knew how to take seriously a machine with a trillion moving parts. It's just mind-boggling." Daniel C. Dennett

Hi,
Can anyone suggest a best way to license my application so it requires an activation.. therefore, application will be protected from being shared with others?
Is there a free tool within Visual Studio or a free third-party?

Maybe this SO thread[^] is going to help you.
Or maybe this one[^] is of use to you.
However, there are a few things you need to think about first:
- Activation
Is your key validated using a key server, or are you going to use a pattern which proves it to be an original key?
- Storing
I strongly recommend you to encrypt the key stored on the disk by using a hash
- Signign
Do you want to sign the key, and your assembly (not directly related, but worth a thought)

You could have also pointed him to a few articles here on CodeProject...

Why wouldn't you want your application to become popular?

The best way is a legally binding contract which was created by a competent attorney.

A List box has a property called "Opacity",which you can set to a value between 0 and 100 to make your listbox transparent.

I have to create a web app using ASP .Net and C#. Here we use only IE 8, so I can't use HTML5 and CSS 3 to create this app.
I have to show an organizational chart where data is dynamic and the user has to be able to select a card in the chart and delete it, edit it, and more.
I've been trying with treeview, but it's vertical.
Thank you for your answers, and sorry because the english.

That's about all I can say as you haven't asked a question.
