C# Modal Form on Startup?

Mike S

Hi, everyone!

This is my first post. I have a C# desktop app that I'm developing. My goal is to have this form start up in the foreground such that the end users can't click on any other windows on their screen. I think that this is opening a form "Modally" but I'm not entirely sure.

I've searched quite a bit and have come across a StackOverflow question that's close to what I need:

https://stackoverflow.com/questions/15800081/blocking-screen-access-from-win-form

Most of what I've found is about opening a new form modally. My app is only one form, so I want it to open modally upon startup. I realize this may be an issue when debugging because then how would I step through or stop the application in Visual Studio if everything but my form is locked--so that's another concern. I'm sure I'm missing something. Can someone shed some light on this and maybe offer an example?

Thanks,

Mike

Accepted answer
Yes, you can start your background work before triggering the ShowDialog() function, if you write any code after the function then it will execute only when the form is closed. However, if you share the scenario of what you were wanted to achieve then we will try to provide you the optimal solution

Amit, I believe you do understand my question corrrectly. However, it sounds like even if I have one form, I still need to create a second form and use the .ShowDialog() method. Correct? If so, does that mean I would want to make the form doing the call invisible so as to give the appearance that I only have one form, opened modally?

Thanks,

Mike

So far I understood your question, you have only one form that you want to show as a modal dialog. For that you need another form and use formobj.ShowDialog() function to achieve your goal. Do let me know if I understood something else
