C# how to load a form with marquee progress bar?
问题 I created a loadingForm with only a progress bar with marquee style. In my mainForm I'm trying to do this: //before downloading loadingForm lf = new loadingForm(); lf.Show(); //start downloading //finishdownloading lf.Close(); The loadingForm was shown but the progress bar didn't appear, and the form looked like it was crash. after finishing downloading, the loadingForm was closed and my app continued to run normally. In loadingForm I only have: void loadingForm_Load(object sender, EventArgs
