How to obtain a Motorola (Symbol) Mobile Device Serial Number?
I'm programming the Motorola ES400 which comes with "Symbol" libraries.
There seems to be ways of getting the serial numbers of the various scanners, but not of the actual device itself!
Anyone got any ideas?
Whats the difference between "serial number" (as shown on the device) and "electronic serial number" returned by TerminalInfo?
I just dealt with this on the MC9090 device, which also uses the Symbol libraries (not sure if they are the same, but this is worth a shot). I used reflection because I have devices from different manufacturers and want the same code to run. You could access this field directly from the property or use reflection:
Here is where the property is:
Symbol.ResourceCoordination.Terminalinfo.ESN
Here is my method using reflection:
try
{
Assembly symbolApi = Assembly.LoadFrom("Symbol.ResourceCoordination.dll");
Type terminalInfo = null;
foreach (Type t in symbolApi.GetTypes())
{
if (t.Name == "TerminalInfo")
{
terminalInfo = t;
break;
}
}
LogService.log(terminalInfo.Name);
if (terminalInfo != null)
{
object objTerminalInfo = Activator.CreateInstance(terminalInfo);
PropertyInfo esn = null;
foreach (PropertyInfo info in terminalInfo.GetProperties())
{
if (info.Name == "ESN")
{
esn = info;
break;
}
}
if (esn != null)
{
object objSn = esn.GetValue(objTerminalInfo, null);
sn = objSn.ToString();
}
}
else
LogService.log("TerminalInfo type not found in " + symbolApi.FullName);
}
catch (MissingFieldException e)
{
LogService.log("MissingFieldException, not Symbol Unit: " + e.Message);
}
catch (Exception e)
{
LogService.log("Error in SymbolAPI: " + e.Message);
}
Hope this helps!
Thats fantatic, thanks. The Symbol SDK help didn't find this when searching!
Just used:
Symbol.ResourceCoordination.TerminalInfo Version = new Symbol.ResourceCoordination.TerminalInfo();
return Version.ESN;
Also found this:
Symbol.ResourceCoordination.TerminalInfo Version = new Symbol.ResourceCoordination.TerminalInfo();
System.Text.StringBuilder MyUUID = new StringBuilder("0x") ;
if (Version.UniqueUnitID != null)
{
//this code is actually from the Motorola SDK guid
foreach (byte b in Version.UniqueUnitID)
MyUUID.Append(b.ToString("X2"));
}
return MyUUID.ToString();
Here's the quick and easy VB.Net solution:
Add a reference to Symbol.ResourceCoordination.dll (I found mine here: C:\Program Files\Motorola EMDK for .NET\v2.8\SDK\Smart Devices\Symbol.ResourceCoordination.dll).
Then use the following code to access the ESN (Electronic Serial Number) value.
Dim Version As New Symbol.ResourceCoordination.TerminalInfo
MsgBox(Version.ESN)
Worked great on our MC3190S scanners! :)

I have a piece of code working as expected in Android but not in iOS. Problem is the value of the final variable 'nombre' which in Android gets the expected value, whereas in iOS it gets a different one randomly chosen from the list (specified in codesnippet provided)
public AsignarNombreCDF(){
this.departamentoId = AdministradoresApp.departamentoId;
this.setLayout(BoxLayout.y());
this.setTitle("Asignar Nombre a CDF");
TopBarUtils.addMenuToTopbar(this);
TopBarUtils.addCommandToTopbarMenu(this, "Inicio Departamento", e->{new MenuDepartamento(departamentoId).show();});
try {
Map m = Utils.consultaWebService("newfoldernames", new Object[]{"department", departamentoId});
String folderNameMatrix = (String) m.get("FolderNameMatrix");
Map m_ = (Map) JSONUtils.fromJsonString(folderNameMatrix);
Iterator it = m_.keySet().iterator();
while(it.hasNext()){
String k = (String) it.next();
final String nombre = (String) m_.get(k);
Button b = new Button(nombre);
b.addActionListener(e->{cargarFotos(nombre);});
this.add(b);
}
int y = 2;
} catch (Exception ex) {
Utils.gestionaExceptionUi(ex);
}
}
Problem is that the final variable nombre seems not to assign correctly to the value passed to the button listener. This as already said, only happens in IOS and not in Android, where we never get a mismatch. Any chance that the iOS build system might oversee this situation?. Any ideas how to overcome the problem?

I have to register a plugin on Quick Find search on "Artilce" entity. When user enter any thing in quick find text box on Article entity at that time my plugin execute and return filter the data based on our business logic.
1.What event is fired when we find using quick find.
2.What message passes when this event is fired.
I have tried registering the plugin on RetrieveMultiple message but this is not triggered when we click on search in quick find.
Please help.
We have a Plugin registered on the RetrieveMultiple. We had a business requirement to search for the records, using WildCard by default.
Plugin Registration Details:
Message: RetrieveMultiple
Primary Entity:None
Secondary Entity:None
Pre-Operation
Code:
public const String QueryLiteral = "Query";
public const String LIKE = "%";
public void Execute(IServiceProvider serviceProvider)
{
String ParentEntity = String.Empty;
String OriginalSearch = String.Empty;
// Obtain the execution context from the service provider.
var ContextInstance = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
// Get a reference to the Organization service.
IOrganizationService ServiceInstance =
((IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory))).
CreateOrganizationService(ContextInstance.InitiatingUserId);
// Critical Point here - NOTICE that the InputParameters Contains the word Query
if (ContextInstance.Depth < 2 && ContextInstance.InputParameters.Contains(QueryLiteral) &&
ContextInstance.InputParameters[QueryLiteral] is QueryExpression)
{
QueryExpression QueryPointer = (ContextInstance.InputParameters[QueryLiteral] as QueryExpression);
//Verify the conversion worked as expected - if not, everything else is useless
if (null != QueryPointer)
{
// Check if the request is coming from any Search View
// We know this b/c Criteria isn't null and the Filters Count > 1
if (null != QueryPointer.Criteria && QueryPointer.Criteria.Filters.Count > 1)
{
ParentEntity = ContextInstance.PrimaryEntityName;
OriginalSearch = QueryPointer.Criteria.Filters[1].Conditions[0].Values[0].ToString();
OriginalSearch = String.Format(CultureInfo.CurrentCulture,
"{0}{1}", LIKE, OriginalSearch);
}
ConditionExpression NewCondition = null;
FilterExpression NewFilter = null;
if (null != QueryPointer.Criteria)
{
//Change the default 'BeginsWith'Operator to 'Contains/Like' operator in the basic search query
foreach (FilterExpression FilterSet in QueryPointer.Criteria.Filters)
{
foreach (ConditionExpression ConditionSet in FilterSet.Conditions)
{
if (ConditionSet.Operator == ConditionOperator.Like)
{
if (OriginalSearch != "")
ConditionSet.Values[0] = OriginalSearch;
else
{
OriginalSearch = QueryPointer.Criteria.Filters[0].Conditions[0].Values[0].ToString();
OriginalSearch = String.Format(CultureInfo.CurrentCulture,
"{0}{1}", LIKE, OriginalSearch);
ConditionSet.Values[0] = OriginalSearch;

We have raised a ticket with Microsoft to address this situaation.
The solution they provided was to modify the Database to make the message
SearchByTitleKbArticleRequest available in the plugin registration tool.
I currently dont remember the table that we updated a flag against these messages.
After updating the table we were able to register the plugin against the message
SearchByTitleKbArticleRequest
Then the plugin triggered and we modified the entity collection returned from there.
I want to get auto increment id of inserted row. I know that there is a lot of examples how to do that:
link1
link2
But I use HSQL 1.8.0.10 and following code:
PreparedStatement ps = conn.prepareStatement("insert into dupa (v1) values(3)", Statement.RETURN_GENERATED_KEYS);
throws expection:
java.sql.SQLException: This function is not supported
How to get id if driver does not support the above solution. Is any other way to get auto increment key of inserted row? I want to handle as much as possible drivers. So want to use obove code in try section and use another way in catch section.
Second question: Is possible that database does not support this feature. So even if I use new driver and old database It will still not work? I tried to use hsql 2.3.2 driver but I can not to connect to 1.8.0.10 database.
The following code illustrates how to retrieve generated keys from HSQLDB 2.2.9 and later using the included JDBC 4 driver. This method returns a two element long[]. The first element contains the number of rows that were updated; the second contains the generated key if any:
static final long[] doUpdate( ... ) {
final long[] k = new long[] {0, KEY_UNDEFINED};
PreparedStatement ps = null;
try {
ps = CXN.get().prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
JdbcValue jv;
for (int i = 0; i < data.size(); i++) {
jv = data.get(i);
jv.type().setJdbcParameter(i + 1, ps, jv);
}
k[NUM_OF_ROWS] = (long) ps.executeUpdate();
if (k[NUM_OF_ROWS] > 0L) {
try (ResultSet rs = ps.getGeneratedKeys()) {
final String identColName = idCol.colName();
while (rs.next()) {
if (k[ROW_CREATED] != KEY_UNDEFINED) throw new AssertionError();
k[ROW_CREATED] = rs.getLong(identColName);
}
}
}
} catch (SQLException e) { ... }
finally {
try { if (ps != null) ps.close(); } catch (SQLException e) { }
}
return k;
}
I am unable to say whether this approach will work with old versions of HSQLDB.
You will have to use some vendor-specific solution, i.e. in mysql you would call LAST_INSERT_ID function.
I don't have valid installation of HSQL to test it, but you can give a try to the highest voted solution from this topic: how to return last inserted (auto incremented) row id in HSQL?
What I want to do is to get the available branches that I can merge to. Pretty much the same as the dropdown when you say merge in TFS2008 and you select the destination branch.
However, it's been very hard to find how.
Below code is a merge between some of the resources I've found in the web, but none seem to work. My guess is that if VS2008 can do it, I can do it thru the SDK, right?.
The below code always give me the same result all the time.
My repository is something like this:
Development
Version1
Code
Version2
Code
Version3
Code
Main
Code
And normally I branch Main > Version X. So the merging can be done Main > Version X and Version X to Main.
The below code always gives me the children of the Main, even if I'm querying (tfsParentBranchPath) with Version3 folder.
Is this because perhaps I used TFS2010 web service but pointing to TFS2008 (that's why I marked some methods that do not work in the code)?
Well please let me know, if someone knows the answer.
Thanks!
public string[] GetChildBranchesToMerge(string tfsParentBranchPath)
{
var versionControl = teamFoundationServer.GetService<VersionControlServer>();
//not supported by tfs2008
//ItemIdentifier[] identifiers = versionControl.QueryMergeRelationships(tfsParentBranchPath);
//var allBranches = versionControl.QueryBranchObjects(new ItemIdentifier(tfsParentBranchPath), RecursionType.OneLevel);
List<string> childs = new List<string>();
ItemSpec[] specs = new ItemSpec[] { new ItemSpec(tfsParentBranchPath, RecursionType.OneLevel) };
BranchHistoryTreeItem[][] branchHistoryTree = versionControl.GetBranchHistory(specs, VersionSpec.Latest);
if (branchHistoryTree.Length > 0 && branchHistoryTree[0].Length > 0)
{
var treeItem = branchHistoryTree[0][0];
if (treeItem.Children.Count > 0)
{
foreach (BranchHistoryTreeItem tia in treeItem.Children)
{
childs.Add(tia.Relative.BranchToItem.ServerItem);
}
}
}
return childs.OrderBy((s) =>
{
return s;
}).ToArray();
}
Finally, this is the last version that works!.
First, I stopped using VS2010 assemblies and it's much faster now.
Second, the big difference is this line:
var treeItem = branchHistoryTree[0][0].GetRequestedItem();
I really dont know why the difference, but it seems without that method, the item returned is a generic one.
public string[] GetChildBranchesToMerge(string tfsParentBranchPath)
{
DoLog("Getting child branches for {0} ...", tfsParentBranchPath);
VersionControlServer vcs = (VersionControlServer)teamFoundationServer.GetService(typeof(VersionControlServer));
List<string> childs = new List<string>();
ItemSpec[] specs = new ItemSpec[] { new ItemSpec(tfsParentBranchPath, RecursionType.OneLevel) };
BranchHistoryTreeItem[][] branchHistoryTree = vcs.GetBranchHistory(specs, VersionSpec.Latest);
if (branchHistoryTree.Length > 0 && branchHistoryTree[0].Length > 0)
{
var treeItem = branchHistoryTree[0][0].GetRequestedItem();
AddChildBranch(childs, treeItem, tfsParentBranchPath);
if (treeItem.Children != null && treeItem.Children.Count > 0)
{
foreach (BranchHistoryTreeItem tia in treeItem.Children)
{
AddChildBranch(childs, tia, tfsParentBranchPath);
}
}
}
DoLog("{0} child branches found", childs.Count);
return childs.OrderBy((s) =>
{
return s;
}).ToArray();
}
private void AddChildBranch(List<string> list, BranchHistoryTreeItem itemToCheck, string tfsParentBranchPath)
{
if (itemToCheck.Relative.BranchFromItem != null && itemToCheck.Relative.BranchFromItem.DeletionId == 0 && itemToCheck.Relative.BranchFromItem.ServerItem != tfsParentBranchPath)
list.Add(itemToCheck.Relative.BranchFromItem.ServerItem);
if (itemToCheck.Relative.BranchToItem != null && itemToCheck.Relative.BranchToItem.DeletionId == 0 && itemToCheck.Relative.BranchToItem.ServerItem != tfsParentBranchPath)
list.Add(itemToCheck.Relative.BranchToItem.ServerItem);
}
Okay, I have a WCF service which is going to be acting as a way to access my SQL database. That part has become largely irrelevant to this question, since for some reason my WCF service crashes. Or, at least, it causes my client Silverlight application to crash. This is why I come here to ask you guys about it.
So here's the code. Bear in mind that it is called asynchronously from my Silverlight client. When it is done, the string that is returned from this method is put on the screen for the client.
public string AddClients(IEnumerable<Client> newClients)
{
int nAdded = 0;
int nelse = 0;
string str = "";
List<Client> newClientsList = newClients.ToList();
List<Client> existingClients = dc.Clients.ToList();
List<Client> clientsToAdd = new List<Client>();
return newClientsList.Count.ToString();
foreach (Client client in newClientsList)
{
var clt = existingClients.FirstOrDefault(c => c.ClientName == client.ClientName);
if (clt == null)
{
return clt.ClientName;
//str = str + " found: " + clt.ClientName + "\n";
//dc.Clients.(clt);
//existingClients.Add(clt);
// clientsToAdd.Add(clt);
nAdded++;
}
else
{
nelse++;
}
}
if (nAdded > 0)
{
//str = str + " more than one nAdded";
// dc.Clients.InsertAllOnSubmit(clientsToAdd);
// dc.SubmitChanges();
}
return nelse.ToString();
}
You may be able to figure out what's supposed to be happening, but most of it's not happening now due to the fact that it's not working out for me very well.
At the moment, as you can see, there is a return quite early on (before the foreach). With things as they are, that works okay. You press a button in the client, it makes the call, and then returns. So as it is, you get '3' returned as a string (this is the size of newClients, the parameter). That is okay, and at least proves that the service can be connected to, that it returns messages okay, and what not.
If I remove that top most return, this is where it gets interesting (well, problematic). It should either return clt.ClientName, in the if (clt==null) condition, or it should return nelse.ToString() which is right at the end.
What do I actually get? Nothing. The method for the completion never seems to get called (the message box it shows never appears).
I've commented most of the stuff out. Surely it has to get to one of these conditions! Have I missed something really obvious here? I really have been attempting to debug this for ages, but nothing! Can someone see something obvious that I can't see?
For the record, 'dc' is the data context, and dc.Clients is a list of Client entities.
I could be missing something, but won't this throw a NullReferenceException? That has to be at least part of your problem.
if (clt == null)
{
return clt.ClientName;
...
I dont understand why you are trying to return the name of the first newly found client from the list you received. Why not just return an integer with total count of newly found clients that you are inserting in the database.
Try:
public string AddClients(IEnumerable<Client> newClients)
{
string str = "";
List<Client> newClientsList = newClients.ToList();
//to save processor and network
List<string> existingClients = dc.Clients.Select(x => x.ClientName).ToList();
List<Client> clientsToAdd = (from nc in newClientsList
join ec in existingClients on nc.ClientName equals ec into nec
from ec in nec.DefaultIfEmpty()
where ec == null
select nc).ToList();
if (clientsToAdd.Count > 0)
{
dc.Clients.InsertAllOnSubmit(clientsToAdd);
foreach (Client c in clientsToAdd)
str += "found: " + c.ClientName + "\n";
return str;
}
return "0 new clients found";
}
easier, simpler, cleaner.
