• Michael Grau Sync data between desktop and pocket pc

• Shahid Mahmood custom pushpins in layer

  I've seen some examples of GeoRSS layers that don't seem to use the default pushpin. How do you specify custom pushpins for points loaded from a GeoRSS doc Oh excellent, do you know if there is some way to control the style of the pushpin, like there is when you add an individual pushpin thanks very much for the help You need to specify VELayerSpecification.IconUrl to the icon image you want to be displayed. There some limitations with GeoRSS layers. One is you have to set the same icon for all pins, the other is the map will be zoomed and panned to fit all the pins. Also if you have more then 200 pins the control is very slow. If ...Show All

• Olle SW client certificate authentication in Pocket PC 2003

  We are running a hand-held terminal application written in VS2005 C# that uses a web service to upload and download data. It had been working fine with both http and https (using TrustAllCertificates code), until certificates were loaded on our servers and client certificates were loaded on our machines in current_user. Now we get the following error: "Error loading user data: ConnectError." For security reasons, we may not move the certificates to the local_machine. We have been told that .NETCF does not support client certificate authentication but we may be able to get around the problem with custom headers. So far we have been unable to integrate the code we were given into our existing application. We would like to know if this is ...Show All

• K_Dean Array.Resize

  I'm trying to dynamically resize an array of objects and getting a error: Error 1 The type arguments for method 'System.Array.Resize<T>(ref T[], int)' cannot be inferred from the usage. Try specifying the type arguments explicitly. D:\Code\CSharp\StuntFighter2000\StuntFighter2000\StarField.cs 89 17 StuntFighter2000 I'm confused what this means my code is: Array .Resize( ref cStarArray, 210); cStarArray is declared as: private Array cStarArray = Array .CreateInstance( typeof ( Star ), 200); Any thoughts Not the same type so that isn't going to work. Try "Star[] cStarArray = new Array[200];" instead. Thanks, Mario and ...Show All

• bioan sending/receiving datasets from webservice

  Hi If sending/receiving datasets  from webservice is mandatory in an application , is there any better solution in CFv2.0 in replace of using dime attachments Can i use   XmlSerializer    to convert datasets to bytes and pass that as parameter to webmethods or add to soap attachment instead of the dataset itself Please advice Thanks Gauls   Just declare Web method which takes/returns dataset, framework would take care of the rest. Why do you believe XML serializer would serialize into "arraybytes" and not to XML I'd say you would get XML from it, hence the name. In fact, here's little secret: both SOAP serializer and XML se ...Show All

The vast majority of limitations like this are driven by carriers. Simply speaking, they would not allow a device on their networks that does not restrict what application can do. Among those things are - not being able to record call audio stream or intercept it in some way - not being able to play audio into phone call - not being able to retrieve IMEI, be a messaging plugin, call privileged APIs of all sort including those setting networks parameters and otherwise interoperatinng with network (unless you are signed with a privileged ...Show All

• JIM.H. Hand held device slow in performance

  I am developing an application for hand held device to scan 2D barcode using Visual C#. However, after scanning for 20 barcodes, the device will experience slow performance and sometimes lag. I experiment using Pocket Word to scan the barcodes. By scanning 1 barcode (normally consists of 10 lines), wait for the data to appear and highlight all data to clear off before scanning the next barcode. The experiment after 20 times, the data will slowly appear, sometimes even lag. And the response of the handheld device becomes slower. Does anyone experience such an issue Is there any improvement that we can do to modify the codes You should look into your source code. Are you creating too many objects ...Show All
