I am using Telerik reports in our app and it is being accessed mostly through an RDP session running in "app mode". Everything works fine locally but when I put it on the TS machine it freezes after the print dialog comes up.
The standard print dialog comes up and you can choose the printer and hit ok but then a small box opens with header of Printing... and then never does anything.
I am not sure what code to post since its fine locally, let me know what you want to see. also printing other things like the Telerik grids and charts are fine.
Found the answer on my own.
I created a standard printdialog screen and "rolled my own" print method and all seems to be good. Hope this helps someone else.
private void reportViewer1_Print(object sender, CancelEventArgs e)
{
this.Cursor = Cursors.WaitCursor;
e.Cancel = true;
try
{
PrintDialog pd = new PrintDialog();
pd.PrinterSettings = new System.Drawing.Printing.PrinterSettings();
var result = pd.ShowDialog();
if (result ==DialogResult.OK)
{
// Print the report using the custom print controller
var reportProcessor
= new Telerik.Reporting.Processing.ReportProcessor();
reportProcessor.PrintReport(this.reportViewer1.ReportSource, pd.PrinterSettings);
}
}
catch (Exception ex)
{
Program.ExceptionHandler(ex);
}
this.Cursor = Cursors.Default;
}

I've created an object previously that I'm now trying to update in an "edit" screen
The id of the object is correct (as it correctly queries earlier in the activity to update the text labels. This should save when a button is clicked.
ParseQuery<ParseObject> query = ParseQuery.getQuery("Product");
Intent i = getIntent();
String queryString = i.getStringExtra("id");
query.getInBackground(queryString, new GetCallback<ParseObject>() {
public void done(ParseObject editProduct, ParseException e) {
if (e == null) {
editProduct.put("productName", ProductName.getText().toString());
editProduct.put("ISDN", ISDN_text.getText().toString());
editProduct.put("expiry", expiry_date.getText().toString());
editProduct.put("type", spinnercategory.getSelectedItem().toString());
editProduct.put("quantity", quantity.getText().toString());
editProduct.put("username", "Admin");
editProduct.put("shoppingList", true);
editProduct.put("mainList", false);
editProduct.saveInBackground();
}
}
});
This is lifted from the Parse Android developers guide, but doesn't appear to be working. Any suggestions
Figured it out. Sort of.
editProduct.put("expiry", expiry_date.getText().toString()); is the line that's breaking it. I'm trying to pass a string to what is defined as a date at the backend, which apparently cancels the whole save operation.
Commented this out in my solution for now until I can fix the issue with the date
In my Windows Phone app's main page, users can click a button to do some stuff and that will trigger the live tile to update.
The problem I am having is, if the user clicks the button and then hit the phone's Back button really quickly, the live tile sometimes will not render properly. This issue rarely happens, but it does happen and when it happens it just looks bad...
The way I implement the live tile is, create a user control that looks exactly the same as the live tile and then save it to isolated storage. Then retrieve it and store it in a FliptileData object. Finally I call the Update method on the ShellTile. Please see the following piece of code to demonstrate the process.
// the function that saves the user control to isolated storage
public Uri SaveJpegToIsolatedStorage(FrameworkElement tile, string suffix, int tileWidth = 336, int tileHeight = 336)
{
var bmp = new WriteableBitmap(tileWidth, tileHeight);
// Force the content to layout itself properly
tile.Measure(new Size(tileWidth, tileHeight));
tile.Arrange(new Rect(0, 0, tileWidth, tileHeight));
bmp.Render(tile, null);
bmp.Invalidate();
// Obtain the virtual store for the application
IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication();
using (IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(IsolatedStorageFileName + suffix, FileMode.Create, myStore))
{
try
{
bmp.SaveJpeg(fileStream, tileWidth, tileHeight, 0, 100);
}
catch (Exception)
{
return null;
}
}
return new Uri("isostore:/" + IsolatedStorageFileName + suffix, UriKind.Absolute);
}
// save the user control to isolated storage and prepare the FlipTileData object
wideFrontTileImage = SaveJpegToIsolatedStorage((UserControl)this.WideFrontTile, "_wide_front", 691);
var flipTileData = new FlipTileData();
flipTileData.WideBackgroundImage = wideFrontTileImage;
return flipTileData;
// update the live tile
var shellTile = ShellTile.ActiveTiles.FirstOrDefault();
shellTile.Update(customTile.GetFlipTileData(data.UndoneMemosCount == "0" && data.TotalMemosCount == "0"));
I think the reason that's causing all this is, when the user clicks the Back button too quickly, the OS terminates all the processes running within the app and the rendering wasn't done at that time. I'm thinking if there's a way to know when the rendering is finished, so I can cancel the Back button and wait until it's finished then manually exit the app. But I simply dunno how...
Any help on this one will be greatly appreciated!
I have ran into similar issue in my WP8 app. The problem was that I was updating my Tile in ApplicationDeactivated event handler. The thing is you should not update your tiles there, but rather in your MainPage.OnNavigatedFrom override. Once I changed this, it works just fine.
I am getting a list of objects in Windows Phone, and show them in a listbox with databinding.
some image urls are not valid, so after every object is added in the list, i run the following code to check and replace, if not valid
private void CheckLinkUrl(Person p)
{
Uri filePath = new Uri(p.img_url);
string correct = p.img_url;
HttpWebRequest fileRequest = HttpWebRequest.CreateHttp(filePath);
fileRequest.Method = "HEAD";
fileRequest.BeginGetResponse(result =>
{
HttpWebRequest resultInfo = (HttpWebRequest)result.AsyncState;
HttpWebResponse response;
try
{
response = (HttpWebResponse)resultInfo.EndGetResponse(result);
}
catch (Exception e)
{
p.img_url = "http://somethingelse.com/image.jpg";
}
}, fileRequest);
}
the problem is that it is very slow, it takes sometimes 2 minutes+ to load every image (although the UI remains responsive, and everything else is displayed immediately in the listbox, apart from the images)
am I doing something wrong? can i get it to run faster?
EDIT:
I tried using the imagefailed event and replace the link, no improvement at the speed of loading the pics
What I have done to avoid this problem in my application is, I have loaded the items with a default Image, The image source is binded to a property in my result item of type ImageSource. By default it returns the default image. After processing or download completion the imagesource value changes to the new Image triggering the NotifyPropertyChanged event and hence it is automatically reflected on the UI. I hope it helps you.
Hi guys Im using Visual Studio 2010 C sharp.
Basically Im building a program and I want to be able to disable certain options after one option is selected. For example when you fill out an online form for something like a job application and it asks do you have a degree? If you select no then the next options below related to the degree question are disabled. That is what I basically want to do.
I couldnt upload the image im affraid :(
Basically as you can see, what I want to do when RDP is selected the 'Site URL' becomes disabled but when any of the other web browser options are selected the 'RDP Connection' is disabled.
Thanks
Hi I figured out how to do this, I thought I would post it here in case it would be any help to anyone else/
Basically it was the use of just and if statement -_-" (cant believe I didnt think of it)
Basically below is a section of my script associated with the combo box I made. There are two options in the combo box, one if internet connection and one is RDP connection. When either one is selected it will 'hide' or 'show' certain data boxes below.
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
if (comboBox1.Text == "Internet Browser")
{
label4.Visible = false;
comboBox2.Visible = false;
btnCreate.Visible = false;
label5.Visible = true;
textBox3.Visible = true;
}
else
{
label4.Visible = true;
comboBox2.Visible = true;
btnCreate.Visible = true;
label5.Visible = false;
textBox3.Visible = false;
}
}
Its basic boolean, if you have any problems, message me and I will help. Happy coding =)
For connecting to webservices i wrote the following code.
WebClient wc = new WebClient();
wc.DownloadStringAsync(new Uri("http://www.Webservices.asmx"));
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted);
void wc_DownloadStringCompleted(object sender,DownloadStringCompletedEventArgs e)
{
Debug.WriteLine("Web service says: " + e.Result);
using (var reader = new StringReader(e.Result))
{
String str = reader.ReadToEnd();
}
}
by using above code Get the string result.But i want get the result in HTMLVisulaizer then i know the what are the methods having that webservice.then i can easily access the particular method.
Please tell me how to call a web service method in Windows phone 7?in webservice i am having 5 webmethods.how to get that and how to call the Particular webmenthod.
Please tell me thanks in advance.
#venkateswara Are you talking about obtaining a list of known WebReference methods so you know which one to call in you code? Do you not see the this of known method calls when you add the WebReference to your WP7 project? Since you will be developing the WP7 app in VS I can't see the reason you would want to do this. Even if you don't own the webservice yourself, you will need to connect to it from VS in order to add the reference to your project.
Below is the screen in VS2010 where a WebReference is added. The Operations are listed on the right.
Once added you can use the ObjectBrowser to understand how the methods should be called.
Please let me know if I have missed something from your question.
#Jason James
The first step:
You must add referent Services ,like Jason James has very detailed instructions .
step 2 :
You can open App.xaml.cs , in Functions Apps
public Apps()
{
// Global handler for uncaught exceptions.
UnhandledException += Application_UnhandledException;
// Show graphics profiling information while debugging.
if (System.Diagnostics.Debugger.IsAttached)
{
// Display the current frame rate counters.
Application.Current.Host.Settings.EnableFrameRateCounter = true;
// Show the areas of the app that are being redrawn in each frame.
//Application.Current.Host.Settings.EnableRedrawRegions = true;
// Enable non-production analysis visualization mode,
// which shows areas of a page that are being GPU accelerated with a colored overlay.
//Application.Current.Host.Settings.EnableCacheVisualization = true;
}
// You can declare objects here that you will use
//Examlpe: NameservicesReferent.(Function that returns services) = new NameservicesReferent.(Function that returns services)();
Ws_Function = new Nameservices.ServiceSoapClient();
}
step 3:
in Mainpage.xaml.cs
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted += new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
GlobalVariables.***NameWedservise***.getLinkAdvertiseIndexAsync("**parameters to be passed**");
step 4:
void Ws_advertise_getLinkAdvertiseIndexCompleted(object sender, advertise.getLinkAdvertiseIndexCompletedEventArgs e)
{
//function returns the results to you, the example here is an array
string[] array = null;
try
{
array = e.result;
if(array != null)
}
cath(exception ex)
{
}
finally
{
array = null;
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted -= new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
}
}
