I have an TMemo in my form, which i need to update with some textlines, while calling different unpredictable and slow functions, which collects its information by REST based API's.
When clicking a button, an OnClick event fires, which shall run theese REST based APIs:
MemoResultServer is a TMemo.
...
void __fastcall TTileBlockForm::TestResultServerClick(TObject *Sender)
{
MemoResultServer->Lines->Append("Connecting... (please wait!)");
try{
RESTRequest1->Execute();
}
catch(...)
{
MemoResultServer->Lines->Append("An error occured during testing...");
return;
}
MemoResultServer->Lines->Append("Returned!");
MemoResultServer->Lines->Append("'Winner': "+FDMemTable1->FieldByName("username")->AsString);
}
...
The problem here is that nothing gets written to MemoResultServer Form, until the function is finished. This causes the user to wait not knowing that the RESTRequest->Execute() has started...
Have tried BeginUpate / EndUpdate ( calling EndUpdate in front of the RESTRequest->Execute() line.
MemoResultServer->Paint wont work either and Repaint is protected...
Any suggestions ?
Appmethod v1.15 with update 1.
