Hi Sherzod
In MainModule:
EmployeeTable.CommandText:='select * from employee WHERE ID='''+ '8180'+'''' <Works perfectly ie EmployeeTable opens and only data where id=8180 is shown>
In LoginForm:
UniMainModule.cUsername:=UserNameUniEdit.Text; <input as 8180 & value verified in MainForm as 8180> <cUsername declared as public in MainModule>
Problem in MainModule
EmployeeTable.CommandText:='select * from employee WHERE ID='''+ cUserName+'''' <EmployeeTable opens with no data>
EmployeeTable.CommandText:='select * from employee WHERE ID='QutotedStr(cUserName) <EmployeeTable opens with no data>
EmployeeTable.CommandText:='select * from employee WHERE ID=cUserName <EmployeeTable does not open at all>
Can someone assist in correcting the CommandText syntax

TQ. Have used a TUnilabel.caption on MainForm to verify the cUserId input.

Hello,
In general, your approach is wrong...
\FMSoft\Framework\uniGUI\Demos\Desktop\LoginForm
http://unigui.com/doc/online_help/index.html?best-practices.htm
Hi Sherzod
I understand the concept in the LoginForm but what I want to do is simple. Once logged in, I want to use the User ID to be used to filter to only show data belonging to the logged in UserId. How do I do that ?

You should do all the user credentials checking in the login form, so when you close the login form the user is considered authorized and logged in.
SO there are two ways out of the login form, and you determine that before you leave the form:
modalResult:=mrOK - user is logged in
modalResult:=mrCancel - user failed authorization

Hi Farshad/Sherzod
1. Started new project
2. Added LoginForm via Unigui Wizard
3. Added UniEdit1: TUniEdit;
4. Declared cUserID: string as public5. Input UniEdit1.Text=8180 in Login Form
5. cUserID:=trim(UniEdit1.Text) ;
6. Press OK to proceed to MainForm7. ShowMessage( cUserID) in MainForm shows no value (expect to see 8180)
Q. Why is public variable cUserID not visible in MainForm ?
How can I make public variable cUserID visible in MainForm ?

sorry my bad, was half asleep
cUserName:string;

EmployeeTable.CommandText:='select * from employee WHERE ID='+cUserName ;
you only need quotedtsr() function if ID is string
There is nothing wrong with your suggested SQL syntax,
I have identified the problem.
The basic problem is that cUserName:=trim(UserNameUniEdit.Text) in the UniLoginForm , though declared as public is NEVER passed to Main.pass

then change cUsername or use cUsernameID as integer
cUsernameID := StrToIntDef(trim(UserNameUniEdit.Text), 0);
then EmployeeTable.CommandText:='select * from employee WHERE ID='+ cUserNameID ;
will work

cUserName:string;
cUserNameID:integer;cUsernameID:=StrToIntDef(trim(UserNameUniEdit.Text),0) ; <compile ok>

Hi Sherzod
I have a simple login form created via Uniform Form wizard and
1. assign as public cUsername:string
2. cUsername:=trim(UserNameUniEdit.Text); eg 8180
I checked the value via showmessage at LoginForm and confirm as 8180
But I suspect that though declared as public in both loginForm & MainModule, cUserName is no longer 8180 at MainModule
Q. How can I check the value of cUserName at MainModule as showmessage don't work there
Please revert. TQ

Hi epos4u
Can compile but have same effect as
EmployeeTable.CommandText:='select * from employee WHERE ID='''+ cUserName+'''' ;
ie EmployeeTable opens but no data shown. Beginning to suspect the value of cUserName is not 8180 though 8180 is input

Why quote the ID, as it is probably an integer?
If this works:
EmployeeTable.CommandText:='select * from employee WHERE ID=8180';
then this works:
EmployeeTable.CommandText:='select * from employee WHERE ID='+ cUserName;
Hi Ron
Your suggestion can compile but the Employeetable is not opened at all 😞

Hi Sherzod
Have already figured that outHave 2 pages

Hi Sherzod
Thanks for the speedy response :-)
Is there a much simpler example ?
Maybe a simple menu or button and upon clicking will launch another form
-
Hi
In Delphi, its trivial to call another form via a menu, button etc via a click event.
I have taken a look at the AllFeatures demo, mdemo but cannot understand nor see how this is done.
Can anybody clarify.
TQ

Wonderful :-) Now to decide whether to purchase Whole or start with Professional as currently no immediate plans for mobile development.
Please confirm that I am able to upgrade from Professional to Whole by just paying the difference at a later date.

HI Farshad
I routinely use 2 laptops in my daily work
1. Lenovo - Win 8.0 (D10.3.3 CE) + IIS8
2. Asus - Win 8.1 (D10.3.3 CE/D7) + IIS 8
When I buy the licenced copy, can i install in both my laptops.

Hi Farshad
Recompiled using User Authentication, the result is worse, the expected login prompt does not appear and nothing is loaded.
FYI, the standalone version displays a login prompt & upon authentication, the UniDBGrid appears with loaded data.What's happening ?
What do I have to do to get the DLL version to work ?
After 4/5 days of testing the trial, its kind of demoralising as basic deployment of as simple DLL don't even work.
Your assistance is most appreciated.
Thank you.
Its weird, I am now able to deploy localhost/isapi/ess4ua.dll compiled with User Authentication
ess4wa compiled with Windows Authentication only display a blank UniDBGrid
