Count total number of records in axapta x++

Sometimes, we need to know the number of records in a axapta x++ query... so it's possible! Just we use the SysQuery::countTotal(queryRun) function to count the number of query records.
However, this function count only the number of records of the first datasource... if we need to count the number of records of a query with more than one datasources... we need to use the SysQuery::countLoops(queryRun) instead of SysQuery::countTotal(queryRun).

Passing values between form and class

Class name is EmplDuplication and Form is EmplTable . void clicked() {    MenuFunction mf;    args args = new Args();    ;     args.record(EmplTable);     mf = new menufunction(identifierstr(EmplDuplication), MenuItemType::Action); mf.run(args); } Meanwhile, in the main() method of the EmplDuplication class, we need to put this Axapta x++ code to get the datasource: static void main(Args args) {     EmplDuplication EmplDuplication; EmplTable localEmplTable; ;     if(args.record().TableId == tablenum(EmplTable)) localEmplTable = args.record();     ... }

What does this mean: "The form datasource query object does not support changing its AllowCrossCompany property after the form has executed the query."?

I have made a form with datasources vendtable and vendtrans. Inside vendtable_ds.executequery() looks like this: QueryBuildDataSource queryBuildDatasource ,queryBDS_VendTrans_Invoice; ; queryBuildDatasource = this.query().dataSourceTable(tablenum(vendtable)); queryBDS_VendTrans_Invoice = this.query().dataSourceTable(tablenum(vendtrans)); if (curext() == "MASTERCOMP") { this.query().allowCrossCompany(true); } else { this.query().allowCrossCompany(false); } //FilterVendorName = stringedit control on form if (FilterVendorName.text()) { queryBuildDatasource.addRange(fieldNum(VendTable,Name)).value(strfmt("*%1*", FilterVendorName.text())); } else { queryBuildDatasource.clearRange(fieldNum(VendTable,Name)); } //FilterInvoiceNumber = stringedit control on form if (FilterInvoiceNumber.valueStr() == "") { queryBDS_VendTrans_Invoice.enabled(false); } else { queryBDS_VendTrans_Invoice.enabled(true); queryBDS_VendTrans_In...
