Create Alert using X++ codes

Create Alert using X++ codes

Sometimes Infolog message is not sufficient enough for prompting information to users. It is possible to create alert message using code as an alternative. It is fairly simple to create alert message manually by just inserting a new record in EventTable where all the alert messages are stored. Below is a code snippet for creating alert using code in AX 2009.
Try following code......





static void CreateAlertUsingCode(Args _args)
{
EventInbox          inbox;
;
inbox.initValue();
inbox.ShowPopup     = NoYes::Yes;
inbox.Subject       = "This is the Alert subject";
inbox.Message       = "This is the Alert message";
inbox.AlertedFor    = "This alert is just information no links are available";
inbox.SendEmail     = false;
inbox.UserId        = curuserid();
inbox.TypeId        = classnum(EventType);
inbox.AlertTableId  = tablenum(Address);
inbox.AlertFieldId  = fieldnum(Address, Name);
inbox.TypeTrigger   = EventTypeTrigger::FieldChanged;
inbox.CompanyId     = curext();
inbox.InboxId       = EventInbox::nextEventId();;
inbox.AlertCreatedDateTime = DateTimeUtil::getSystemDateTime();
inbox.insert();
}

SysQueryRangeUtil class -Use method name as query criteria(Reports)

SysQueryRangeUtil class - use method name as query criteria

This is a cool new feature in AX 2009 - you can now use a method name instead of literal value in query criteria!

For example, if you run a report every month, previously you need to change the date criteria in each month you running the report 

(ie.“01/06/2010..30/06/2010”,  “01/07/2010..31/07/2010”, etc).
Now you only need to enter (monthRange(0, 0)) which will automatic return the correct first day and last day of the month.

For Example: - 

You can also refer to the SysQueryRangeUtil class – there are a lot of useful methods such as dateRange(), currentEmployeeId(), etc. It’s also possible to create new method on this class for special purpose. But do this with caution.

Finding all data sources in a form through Job

Finding all data sources in a form through code

Hi ,

Here is small trick to find the datasource in form. Open job node , and a new job and copy paste following code over there,.....

static void AllDataSourcesInForm(Args _args)
{
    Args args = new Args();
    FormRun fr;
    FormBuildDataSource formBuildDataSource;
    counter i;
    ;
    args.name("CustTable");   // its your FORM name
    fr = ClassFactory.formRunClass(args);
    for(i=1 ; i<=fr.form().dataSourceCount();i++)
    {
        formBuildDataSource = fr.form().dataSource(i);
        info(new DictTable(formBuildDataSource.table()).name());
    }
}


When you run this job you get all data source which is used in CustTable Form

Differences among reread(), refresh(),research()

Differences among reread(), refresh(),research()

When working with Forms, commonly after opened the form we need to do some operations with existing data. In few cases we need to interact with data base again and again in order to do. For that we will use these methods. But some times its create confuse what exactly use of these methods, when should we call these methods and why, here is brief info these methods...

refresh() : this method will refresh the data in the data source cache. But it will not interact with the data base to fetch the new/updated record values. What ever values have fetched in the previous query will store in data source cache, this method will just refresh the data source cache only.

reread(): this method will interact with the data base and runs the query against the data base in order to fetch the new/updated record values. But this will not show the updated values in the form until calling the refresh method. that means it will update the data source form cache only but not existing form control values.
So it is better to call the methods as shown here, like reread and after refresh methods in order to fetch the new / updated values from the data base.

formDataSource.reread()
formDataSource.refresh()

research():Calling research() will rerun the existing form query against the database, therefore updating the list with new/removed records as well as updating all existing rows.
