I've looked around and it appears that everything can be editable in a MessageBox, bar the text on the buttons (WPF/C#)
MessageBox.Show("Generic Message", "Caption",
MessageBoxButton.YesNoCancel, MessageBoxImage.Warning)
Is there a way to change the "Yes", "No", "Cancel" text or do I need to write a window to function as a MessageBox to accomplish this? (There isn't any problem doing that; I am just wondering if there is a way in WPF).
You can't do it directly. Short of creating your own MessageBox, you could use Win32.SetWindowText() as described here (convert the VB.NET code here). If you don't want to have to deal with native functions, then a custom MessageBox will be the best option.
You can use whatever buttons are offered by the MessageBoxButton enum. If you want something different, you have to write a custom dialog.

Is there any way to change the "MessageBoxButtons.YesNo" Yes/No order on .Net?
The Yes button is by default on the left and No button on the right, how can I change that?
My code
MessageBox.Show(#"Do you want to confirm?", "Problem!", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation);
I'm using Visual Studio 2013.
Thanks.
No, there is nothing like that. Built-in message box functionality has only few moving parts: message text, title, help page and choice from predefined set of icons and button sets (not mentioning few other minor options).
If you want to suggest the user answer "No" as default one, go with Yes-No buttons and make No the default button using MessageBoxDefaultButton.Button2 (use this MessageBox.Show() overload). This is a standard in handling the need where answer No is preferred/recommended.
So based on your example, you can use
MessageBox.Show(#"Do you want to confirm?",
"Problem!",
MessageBoxButtons.YesNo,
MessageBoxIcon.Exclamation,
MessageBoxDefaultButton.Button2);

I have a populated ListView dialog. If a user clicks on an option in the ListView, a new dialog is shown above the ListView.
My problems is that when I click off of the new top-most dialog (onto the ListView behind it), the new dialog's borders flash/blink several times. The icon on the taskbar also flashes. I wish to disable the flashing, but cannot find a property to change.
To show my dialog, I use the following code:
if (detail == null)
detail = new Details(opt, val, user, desc, m_l);
else
detail = null;
detail.ShowDialog();
This is intended behavior, it's because the new dialog is modal. It's drawing attention to the fact that something needs to be done.
If you need to make a non-modal form, instead of using ShowDialog(), simply use Show().
Sounds like to me you are creating modal windows each time. And you cannot resume the previous dialogs until you dismiss your new top-most window.
Take a look at this wikipedia article for information about modal dialogs.
I would advise you look at how you are creating/showing your windows.
In WPF you show windows via Show() or ShowDialog(), however, I do not know which type of ListView you are using
EDIT:
Per your comment, you want modal dialogs. The only ways I can think of even trying to remove the flashing is going into WINAPI. This doesn't seem like a job for .NET.
I want to suggest a few things:
Take a look at options for showing each window. See this MSDN page
Take a look at the options for styling each window. See this MSDN page
Reconsider your design. I know this may take a lot of work, but having so many layers of windows is kind of unappealing to most users. Ultimately, I believe this option will make your application the best.
Thank you all for your answers and guidance. I have found the best way to handle my problem.
I was using an event ItemActivated. This event was called when an a highlighted item on the ListView was clicked. This became a problem when the user would double click on an already selected item. This would cause the new dialog to show, but also flash several times.
By using the DoubleClick event instead, a single click on a selected object does nothing. A double click on either a selected or non-selected item opens the dialog without the flashes. The flashes still appear if you try to click off of the dialog box, but are not as much of an issue.
I have a messageBox with yes/no buttons.
I want the it's string text be right to left, but the buttons location be at left. and I want to change the buttons text also...
I used the below code:
MessageBox.Show("abc", MessageBoxButtons.YesNo, MessageBoxIcon.None,
MessageBoxDefaultButton.Button1, MessageBoxOptions.RightAlign);
but in this code, the buttons be on the left too. how can I set my personal change in it?
You can not edit this dialog; design your own MessageBox and customize it. For some limited options in this dialog see RightAlign or RtlReading options in MessageBoxOptions Enumeration.
example:
string message = "سلام";
string caption = "سلام";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result = MessageBox.Show(this, message, caption, buttons,
MessageBoxIcon.Question, MessageBoxDefaultButton.Button1,
MessageBoxOptions.RightAlign);
As far as I Know you cannot change/edit the default MessageBox of winforms. However you can create a custom message box. Look at the
Custom Message Box which might be helpful.
You can also have a look at the previously asked question over here
It is very hard to customize MessageBox outside the already provided options. RtlReading option is not meant to be used for cosmetic aligning, but to enable right-to-left scripts (such as Arabic) in left-to-right environment. What you really need is some custom message box. CodeProject has several, so maybe some of them may be useful to you. There are surely more out there on the 'net. When I go to http://www.codeproject.com/KB/dialog/ add filter for .NET and add search for messagebox this is what I get:
FlexibleMessageBox – A flexible replacement for the .NET MessageBox
A versatile MessageBox replacement
Custom Featured MessageBox
MessageBoxManager - A Windows Forms component that provides enhanced MessageBox functionality
One article even describes how to extend system's existing message box, but I don't recommend that approach.
I'm using MessageBox.Show() in a console application for a purpose. But, the header text displayed in the MessageBox is trimmed as it displays ending characters as "...".
Can I set the MessageBox window width to handle this behavior.
Please help me in this regard.
Thanks in advance.
No, in the default MessageBox its not possible to change the size of it. But if you want it, you can create your own message box. Just create a new form, put some buttons inside, in icon if you wanto and some text. And when you want it to show, just simply call ut, like you open the form
See
here
C# formatting a MessageBox
It can't be done. You have to create your own Form mimicking that behavior.
You can try to use the Win32 call SetWindowPos As suggested here.
How do I read a message of standard Win message box (Info)?
Using
SendMessage(this.HandleControl, WM_GETTEXT, builder.Capacity, builder);
I can only read the header of the message box or the text of the button, but not the message itself.
thanks.
Notes (from Q&A):
this.HandleControl is a handler to the message box window
Spy++ shows no child controls bar the button. That's what it made me thinking that Message Boxes have their own way of keeping text w/out using labels
It's a legacy app written with delphi, the button's class is TButton as per Spy++, but still there's no controls except of button inside the dialog window.
After checking a notepad window, both Image & Text are 'selectable', I guess my app doesn't use a std MessageBox. still, how do I go about extracting the text out of the thing? I can see that no labels in my delphi app can be selected by Spy++ Finder tool.
The message text is in a label control on the modal MessageBox dialog window. You have to get the window handle to the MessageBox dialog (win32 API FindWindow) then retrieve the window handle to the control (win32 API GetDlgItem) and then retrieve the text from that window win32 API GetWindowText).
EDIT --
TCHAR text[51] = {0};
HWND msgBox = ::FindWindow(NULL, TEXT("MessageBoxCaption"));
HWND label = ::GetDlgItem(msgBox, 0xFFFF);
::GetWindowText(label, text, sizeof(text)-1);
Try simulating a copy operation (Ctrl-C), then fetch the text from the clipboard: messageboxes allow copying the whole content that way (if they're properly done).
The OP commented that: that worked, thanks. I might end up with doing it that way. Ideally we wanted to keep our implementation focus independant, but choosing between a dedicated PC and OCR I'd probably go the first route.
Personally I've tested this in Delphi 6 and it comes out looking like this:
---------------------------
Confirm
---------------------------
You are about to close the program
WARNING: Are you sure?
---------------------------
Yes No
---------------------------
