Hi All,

I am using QFileDialog::getSaveFileName method to get a save dailog. It asks for new file name. When i give "abc:c" as a file name it pops up a message stating "The file name is invalid. But in case if i give file name as "abc?c" or "anc*c". It doesn't give any error. Though the dialog doesn't accept that input file name but it doesn't give any error.

Please let me know what can i do to get a error message in case of "abc?c" or "anc*c" as a file name.

Thanks in advance

I would guess that is because the ? and * are used as wild-card indicators in filenames. You would need to test for them yourself.

Thanks for the reply.
I agree with your explanation, But how can i check for existence of ? or *. Since this QT widget itself takes care of other invalid characters. Moreover in case of ? or * characters the dialog doesn't return anything. Otherwise i would have checked for these characters in the returned string.

Do you have any idea how can i achieve this.

This is an issue with Windows, as I said above. I have just tried something similar using a simple Win32 program and the ? in the name just restricts the dialog to showing any names which match. The user must then select a specific name to get the dialog to proceed.
