POC# WinForm BackgroundWorker not Updating Processbar
text
Body
copied!<p>I am having a little trouble with getting the backgroundworker to update my progress bar. I was using a tutorial online as an example, but my code is not working. I did some digging on this site and I can't find any kind of solution. I am new to the backgroundworker/progress thing. So I don't understand it fully.</p> <p>Just to set things up: I have a main form (FORM 1) that opens another (FORM 3) with the progress bar and a status label. </p> <p>my Form 3 code as is:</p> <pre><code>public string Message { set { lblMessage.Text = value; } } public int ProgressValue { set { progressBar1.Value = value; } } public Form3() { InitializeComponent(); } </code></pre> <p>My Form 1 Partial Code:</p> <pre><code>private void btnImport_Click(object sender, EventArgs e) { if (backgroundWorker1.IsBusy != true) { if (MessageBox.Show("Are you sure you want to import " + cbTableNames.SelectedValue.ToString().TrimEnd('$') + " into " + _db, "Confirm to Import", MessageBoxButtons.YesNo) == DialogResult.Yes) { alert = new Form3(); //Created at beginning alert.Show(); backgroundWorker1.RunWorkerAsync(); } } } private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { BackgroundWorker worker = sender as BackgroundWorker; int count = 0 foreach(DataRow row in DatatableData.Rows) { /*... Do Stuff ... */ count++; double formula = count / _totalRecords; int percent = Convert.ToInt32(Math.Floor(formula)) * 10; worker.ReportProgress(percent, string.Format("Completed record {0} out of " + _totalRecords, count)); } } private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { alert.Message = (String) e.UserState; alert.ProgressValue = e.ProgressPercentage; } private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { alert.Close(); } </code></pre> <p>So. The problem is its not updating anything. The progress bar nor the label is updating. Can someone point me in the write direction or have a suggestion?</p>
