I try to create a custom MessageBoxImage for the build in MessageBoxResult
For the custom MessageBoxImage enumeration, I have:
public enum CustomBoxImage
{
Foo = new BitmapImage(new Uri(#"pack://application:,,,/MySoftware;component/Images/foo.png"))
}
and the MessageBoxResult, I have:
MessageBoxResult mrb = MessageBox.Show(
"This will kill you. Are you sure?",
"Kill you",
MessageBoxButton.YesNo, CustomBoxImage.Foo);
But it gives me this error:
Cannot convert from "...CustomBoxImage" to "System.Windows.MessageBoxImage'
How can I insert a customized image enumeration into MessageBoxResult? Or, is it even possible?
You can't customize the message boxes beyond the given options. If you need a fully customized one, you can use a 3rd party component. You can even make a window look fully like a message box and customize it if you really need to.
You can't change the signature of the Show method but you can create a converter between your enumeration and the MessageBoxImage enumeration.
if you want to use things that is not provide by the MessageBox, you can create your own messagebox.

I am familiar with the basics of Excel AddIns, but have no idea how to design, implement and later display an internal dialog.
See standing question with images here:
https://social.msdn.microsoft.com/Forums/en-US/935ebeae-1b88-4609-ba33-b0e522d2797f/how-to-create-a-dialog-for-use-by-an-excel-addin?forum=exceldev
TIA
Notes:
(1) My programming language is C#
(2) I prefer to design dialogs by drawing them.
You can use the MessageBox class, for example:
const string message =
"Are you sure that you would like to close the form?";
const string caption = "Form Closing";
var result = MessageBox.Show(message, caption,
MessageBoxButtons.YesNo,
MessageBoxIcon.Question);
// If the no button was pressed ...
if (result == DialogResult.No)
{
// cancel the closure of the form.
e.Cancel = true;
}
If you want to customize the dialog window on your own, you can add a new Windows Form to the project and then add the required controls. After creating an instance of the form in the code you may show it using the Show or ShowDialog methods.
I have a WinForms application, and when it is finished running, displays a message box with just an OK button.
Is it possible to have an OPEN button on the message box too?
I found this code online:
public static DialogResult Show(string text, string caption, MessageBoxButtons buttons);
But it only gives basic commands, like Yes / No, OK / Cancel, etc. It doesn't show any open button.
I want to OPEN a text file after my program has finished running.
Any help would be greatly appreciated.
No, you can't have any other values in a message box rather than the default, the MessageBoxButtons is predefined enum and you can't add to it. The solution is either use some custom message box, check this, or implement your own MessageBoxForm and add your custom settings to it, check this.
The MessageBox.Show methods exposes serval overloads. You can use one of them as you like. To invoke a MessageBox, simply execute following line:
MessageBox.Show("Hi");
For information you can find on MSDN.
It would be nice to have larger MessageBox Buttons since the target for this application is a tablet.
DialogResult dialogResult = MessageBox.Show(
message, caption,
MessageBoxButtons.YesNo,
MessageBoxIcon.Question,
MessageBoxDefaultButton.Button2);
switch (dialogResult)
{
case DialogResult.Yes:
// ...
It is a system setting. Tablet PCs are normally already configured to make it easy to tap buttons like this so that it works well in any program, not just yours. To configure your tablet, in Win7, use Control Panel + Display, Personalization, Window Color. Click Advanced appearance settings, select "Message Box" in the Item combo. Increase the font size. Don't be fooled by the poor preview, the button will actually grow. There are additional settings in this dialog you might want to tweak to make it easier to manipulate the UI.
A messagebox is just a simple modal form. You can make one yourself and use ShowDialog()
I'm not sure if it's possible or not, but you could use a simple form instead of a dialog box then you can get the design exactly as you wish.
Winforms way? Do you mean, an "automagically via a property change" way? If so, none that I know of.
You can spin up your own custom dialog/form that is bigger and use it instead. While this is not as automagic as the one line MessageBox.Show(), it is not very difficult.
That's not possible with MessageBox which wraps the native system dialog.
You'll need to produce your own dialog or even better see if there is a way to configure the system to give your app (and all others) bigger buttons.
The downside of rolling your own is that you lose all the functionality that the native one provides.
Yeah, going along with what MattP said, you'll need to create a custom form and then use the ShowDialog() method to display the second form as a modal dialog.
private void button2_Click(object sender, System.EventArgs e) {
using (Form2 xForm = new Form2()) {
if (xForm.ShowDialog(this) == DialogResult.OK) {
// Take some action
}
}
}
You can make a 2nd form, then you can make the buttons as big as you want
I am currently developing an application in C# using WPF, I have always only used WinForms. Normally if I want to ask the user a question instead of making my own dialogue I use
DialogResult result = MessageBox.Show(
"My Message Question", "My Title", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
This is the first time that I have used a WPF form and DialogResult does not seem to be available. What do I use to get the same effect?
Here is how you do the same in WPF:
MessageBoxResult result = MessageBox.Show("My Message Question", "My Title", MessageBoxButton.YesNo, MessageBoxImage.Question);
if (result == MessageBoxResult.Yes)
{
// Do this
}
Use MessageBoxResult instead. And use the MessageBox class. But this message box will look pretty ugly "classic" style.
Another option would be to use Extended WPF toolkit
Yet another option would be to go here and download CrossTechnologySamples.exe then look into the VistaBridge project. I recommend you give a good look here because you will find other samples for other dialogs (like FileOpen, FileSave etc.) that do not exist by default in WPF.
in C# winforms when we display a message box it has no title in the title bar and no title in its button that is in the task bar.
What if i want to set title and icon for a message box.
one option is that create a form that appears and behaves like a message box and i show and hide it when i want. yes that can be done but i want to modify the "MessageBox"
Use a MessageBox.Show overload such as:
public static DialogResult Show(
string text,
string caption,
MessageBoxButtons buttons,
MessageBoxIcon icon
)
passing your title bar text in caption and your icon in icon e.g.
MessageBox.Show("Oh noes!", "My Application", MessageBoxButtons.OK, MessageBoxIcon.Error);
There is an overloaded version of show message box that will accept a title string and let you specify the icon and number/type of buttons.
The MessageBox.Show method has a bunch of overrides that allow you to set the properties of the pop-up.

One short 2 line answer , your name space using System.Windows.Forms; will already be there , in message box you need to pass all parameters , it might not work if you uses only icon
using System.Windows.Forms;
MessageBox.Show("yourmessage","yourTitle",MessageBoxButtons.OK,MessageBoxIcon.Error);
