    - PDA Web Service 401 error Hi all I have a simple helloworld webservice that I can access from my labtop. However I can't consume its methods from my pda. I'm using the same network credentials and preauthentication on both platforms, ws.Credentials = new NetworkCredential(UserName, Password, "DOMAINNAME"); ws.PreAuthenticate = true; yet calling ws.helloworld() on my pda throws a WebException with value WebException, digging deeper the status code reveals its a http 401 authorization response. Any ideas?? Tag: ADO.NET driver for the compact framework Tag: 32723

    - hide taskbar I am developing an application with VB .Net on a Win CE 4.1 Symbol device. I am continuing to have a problem with some code.

    - Memory 'leak' at Webservice executing... Hi... I use a webservice on PPC. It can download more megabytes of data in a DataSet (I have tried with a 1,1MB DataSet). After closing the function of the webservice, it seems DataSet is still in the memory because I have very few free memory. I have tried to GC's Collect method: (after that I called GetTotalMemory) TotalMemory before reset: 1724716 TotalMemory after reset: 790636 It seems GC does its work, but the real free memory does not getting higher (checked in Setting->System->Memory) I have tried with a 11MB dataset too -> I closed the webservice's class but free memory remains very few... so later the system crashed, I had to push the reset button on PPC. The situation is the same when I am trying to Compact a 4MB SqlCe database with SqlCeEngine's Compact method. Mmemory usage getting higher by about 4MB, and after disposing engine (and call GC.Collect) I cannot get back that 4MB... (but calling Compact method again does not require another 4MB) Does anybody know what I do wrong??? Or is it "normal"? (GC gets more memory for the app and does not give it back?) Or what? :) Thanx for answers... Cser Tag: ADO.NET driver for the compact framework Tag: 32718

    - web services deployment and configuration on server? Hi, I have a web service that my Pocket PC app consumes. There are other web services on the same server that are for other devices but for the same project. If I have more than one web service under the same IIS folder do they use the same thread or thread pool on the server or would each web service use its own thread anyway? I guess im just trying to find out if web services are grouped under IIS would they all fail if one fails? Thanks Tag: ADO.NET driver for the compact framework Tag: 32672

The idea is that if there is a change to the schedule, an alert of some sort is transmitted to the device. My idea is to have a socket listening (non-blocking) on a specific port. During logon the public IP address of the device is recorded and then used to send alerts. Is this a good approach? Are there any other approaches? I have also found it difficult to find any examples on the web on this topic. Many thanx for any help you can offer, Mark Tag: ADO.NET driver for the compact framework Tag: 32660

    - Data collection storage options Tough decision for me. I'm faced with the need for RAD - short timeline. I'm replacing an existing handheld app I wrote several years ago for an intermec device using vc1.5 with a newer one written for ppc devices (vb.net cf). My question pertains to what file types to use when storing and manipulating the data on the pda. My old app stored data using random access text files - but it was a bit combersome to develop. I do like sql. The specific ppc devices are yet to be known, but I need to continue development regardless. The app may need to be ported to other ppc devices too (just a side not if its even important at this point). I'm trying to figure out how I should best store and work with the data files (inventory, issues, receipts, transfers) on the pda: Text files, sql ce, other? A parts file will be downloaded (in flat ascii text format) to be used on the pda (user enters a part number, the system will look up the part and display the uom and location) - and this file could be relatively large (several thousand parts possible). My old program retrieves this parts file, via zmodem comm transfer, and immediately parses it into a random access text file (then discarding the original server fed file). When the user enters data (inventory, issues, etc), it is stored in its respective random access file (inv.dat, issues.dat, etc). When the user wanted to upload their collection info, the system would export the data to a flat file and send it, zmodem, to the PC. To build the flat file, the system would read each .dat file in turn and write a record to text file containing all transactions - preceded by a record flag (I=Issues, N=iNventory, etc). The legacy server system cares less how the pda will work with the data when its out in the field, but it does require that it accept the parts.txt file as is, and it requires that the file received from the pda (collect.txt) is in the same spec'd format. Is the 'sqlserver for ce' method the best way to go? Or are random text files handled pretty well (easy to develope and quick to access) under vb.net cf? Any helpful input and or experiences shared would be appreciated, Thanks, Mike Tag: ADO.NET driver for the compact framework Tag: 32577
