  • ProgressBar isn't updating

    - by Nuru Salihu
    I have a progressbar that that is show progress returned by the backgroundworker do_dowork event like below . if (ftpSourceFilePath.Scheme == Uri.UriSchemeFtp) { FtpWebRequest objRequest = (FtpWebRequest)FtpWebRequest.Create(ftpSourceFilePath); NetworkCredential objCredential = new NetworkCredential(userName, password); objRequest.Credentials = objCredential; objRequest.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse objResponse = (FtpWebResponse)objRequest.GetResponse(); StreamReader objReader = new StreamReader(objResponse.GetResponseStream()); int len = 0; int iProgressPercentage = 0; FileStream objFS = new FileStream((cd+"\\VolareUpdate.rar"), FileMode.Create, FileAccess.Write, FileShare.Read); while ((len = objReader.BaseStream.Read(buffer, 0, buffer.Length)) > 0) { objFS.Write(buffer, 0, len); iRunningByteTotal += len; double dIndex = (double)(iRunningByteTotal); double dTotal = (double)buffer.Length; double dProgressPercentage = (dIndex / dTotal); iProgressPercentage = (int)(dProgressPercentage); if (iProgressPercentage > 100) { iProgressPercentage = 100; } bw.ReportProgress(iProgressPercentage); } } However, my progressbar does not update. While searching , i was told the UI thread is being blocked and then i thought may be passing the progress outside the loop will do the trick. then i change to this if (ftpSourceFilePath.Scheme == Uri.UriSchemeFtp) { FtpWebRequest objRequest = (FtpWebRequest)FtpWebRequest.Create(ftpSourceFilePath); NetworkCredential objCredential = new NetworkCredential(userName, password); objRequest.Credentials = objCredential; objRequest.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse objResponse = (FtpWebResponse)objRequest.GetResponse(); StreamReader objReader = new StreamReader(objResponse.GetResponseStream()); int len = 0; int iProgressPercentage = 0; FileStream objFS = new FileStream((cd+"\\VolareUpdate.rar"), FileMode.Create, FileAccess.Write, FileShare.Read); while ((len = objReader.BaseStream.Read(buffer, 0, buffer.Length)) > 0) { objFS.Write(buffer, 0, len); iRunningByteTotal += len; double dIndex = (double)(iRunningByteTotal); double dTotal = (double)buffer.Length; double dProgressPercentage = (dIndex / dTotal); iProgressPercentage = (int)(dProgressPercentage); if (iProgressPercentage > 100) { iProgressPercentage = 100; } // System.Threading.Thread.Sleep(2000); iProgressPercentage++; // SetText("F", true); } bw.ReportProgress(iProgressPercentage); progressBar.Refresh(); } However still didn't help. When i put break point in my workerprogresschanged event, it show the progressbar.value however does not update. I tried progressbar.update(0, i also tried sleeping the thread for a while in the loop still didn't help. Please any suggestion/help would be appreciated .

  • HTML Dynamic Number of Dropdowns

    - by Evilsithgirl
    I have this form on which I would like to create a dynamic number of dropdowns. I have a list of categorized applications which I would like each to have its own dropdown that submits data for each dropdown. The dropdown options will be the same for each. Here is my code. I am not sure how to pass the unique data to the server. As you can see I currently have an iteration over a list of applications that I would like to make each select in that iteration its own dropdown. Thanks in advance. <html:form action="/CategorizeApps.do"> <h3>Uncategorized</h3> <br/> Categorize each application using the dropdown menu then click categorize.<br/> <table class="list"> <thead> <tr class="controls"> <td><input type="submit" name="btnAction" value="Categorize"/></td> </tr> <tr class="fields"> <td>ID</td> <td>Name</td> <td></td> </tr> </thead> <tbody> <logic:iterate id="uncat" name="appsUncat" scope="session"> <tr class="hlist"> <td><bean:write property="id" name="uncat" scope="page"/></td> <td><bean:write property="name" name="uncat" scope="page"/></td> <td><select id="category" name="category"> <logic:iterate id="categories" name="Categories" scope="session"> <option value="<bean:write name="categories" property="id" scope="page"/>"><bean:write name="categories" property="name" scope="page"/></option> </logic:iterate> </select></td> </tr> </logic:iterate> </tbody> </table> </html:form>

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?

This goes well for the smaller files, but for large files this can take a while and the bandfwith is fully used. My question is, is it possible to split large documents and send it piece by piece to the browser? I hold the document as a property of an object.
