I am trying to handle exception in C#...suppose if the program writes to an output file it checks for if file already exists then it should display an error message.
I don't want to use MessageBox.Show() as it comes with an OK button.
I want to use some kinda informational message where user doesnot have to click on any ok button.
any suggestions???
Thank you
You might be looking for a Toast message that shows a notification, then disappears after a short time by itself.
An example for this is shown here.

everyone. We are using XAF framework in our project and I need to show a popup something like "Process was completed successfully" that indicates some process has been done successfully. Can you point any documentation or code snippet?
Thanks, in advance.
a possible implementation can be found at https://github.com/expand/eXpand/tree/master/Xpand/Xpand.ExpressApp/Xpand.ExpressApp/MessageBox
As far as i remember there is no option for showing message boxes in xaf. You need to create your own form and use it to show messages.
is there a way to "copy" the functionality of a MessageBox or DialogBox in Windows Mobile 6.5?
I've developed a custom message box (with paint events and blending etc) to make the UI look better. However, I don't know how to duplicate the MessageBox functionality, where the program "freezes" and "waits" for a response from the user (usually pressing OK or Cancel button).
Right now, as a workaround, I disable the entire screen so that only the message box will receive any key presses. Then have a custom event called OnMessageBoxClosed.
I then put the actual code to be executed based on the choice made by the user (OK or Cancel) in the event handler for the event.
I would prefer if its possible to make this custom message box behave like a regular messagebox.
Thanks!
I have a C# application which uses a System.Windows.Forms.WebBrowser.
The problem is: i'd like the user to navigate smoothly in my application, without prompts, without javascript windows popping up, without security prompts. Even if this requires some contents to be unavailable.
I just want to have one window (always one window, if a receive a new window event, i redirect it to the single window).
How can i do this?
I tried to use this.browser.ScriptErrorsSuppressed = true but i doesnt seem to work.
For example, if i test it on a browser page which performs text validation, i still receive a popup window saying that my text is invalid.
Thank you!
I've found a solution somewhere else, since it wasn't available here.
Here it is: http://www.codeproject.com/Articles/31163/Suppressing-Hosted-WebBrowser-Control-Dialogs
Basically, you have to hook the WM_INITDIALOG message.
It works wonders here.
How can I show a dialog message, similar to MessageBox, which have just the "Cancel" button and can be closed by the application.
The idea is to show the dialog while the application retrieves data from a server, allowing the user to cancel this request, and closing the dialog once the request is completed.
I recall having a very similar problem in the past. I don't think there is a dialog message "out of the box" that works like that. The way I solved this was by writing a class that modeled this sort of behavior in a window and having the application spawn an instance of the window.
The silverlight message box blocks code execution while it is open so it is not possible to close it. However you can use an XNA messagebox in Silverlight which is asynchronous
This explains its use in depth
You can probably then call EndShowMessageBox for your purposes.
if your intention is to let the user know that something is loading and that they should wait. you should use a progressbar instead.
How to: Create a Custom Indeterminate Progress Bar
I'd like to show a messageBox in the setup.
Have how to put this messageBox into a Custom Action?
Because I want to this messageBox appears when one condition is satisfied.
If isn't clear, please, let me know!
EDIT:
I want to make a script to verify if the .exe that I'm trying to execute it's already installed, if don't --> execute, else --> do nothing.
My solution is w.r.t. Installshield 2014 but it is quite common use case to show an error message box during installation based on certain condition. So, this solution might help someone even in case you want to achieve it in an installshield version higher than Installshield 2009.
I achieved it through SpawnDialog control event as discussed below. Let's say you have a dialog with <Back, Next> and Cancel buttons. On the click of Next> button you want to make some check e.g. whether a service is up and running or not.
If service is down then you might want to show an error dialog popup instead of moving to the next wizard step. So this is how you setup your Next> button behavior as shown in the snapshot below:
Now you can notice the SpawnDialog event. I've set it to SetupErrorNew. What is SetupErrorNew? SetupErrorNew is also a dialog. I created it by cloning pre-existing SetupError dialog template as shown in the snapshot below:
This dialog will show the error message that you desire. Few key things that we need to set on the new error message dialog SetupErrorNew as below:
Set the Error Dialog property of the dialog to False.
Error dialog has a number of buttons for Yes, No, Ok, Cancel, Retry, Abort, Ignore options. Delete all buttons except Ok button.
Set the appropriate error message text.
Under Behavior -> For Ok button change the argument value of EndDialog event to Return as shown in the snapshot below:
Use an InstallScript function, there you have a MessageBox().
