How to call a FrontEnd DLL in ABAP Program

In one of our ECC 5 projects, we are requested to call a DLL locates on frontend with SAPGUI 640 installed to read/write a IC card with connected to Frontend. I searched the forum, seems every one refer to Object CL_GUI_FRONTEND_SERVICE and Method 'Execute'. Does Anyone has successful proven story to share? Can any other motheds can be implemented such as GUIXT, COM4ABAP or DotNet Connector? This scenario is meanful in many frontend integration cases. I hope experienced guys can share your valuable points. Thanks a lot.

Hello,
the last post give you the way.
At first build a COM Wraper about your dll, that simple
export the needed functions via a COM (or ACTIVEX) object.
To do this with VB6 as example take a look to
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon98/html/vbconcreatinganinprocesscomponent.asp
After this you can use the ActiveX Controls in the ABAP tutorial.

How to call method excel subtotal in ABAP program

The best way is to start recording a Macro(Tools->Macro->Record New Macro), and then do the operations (like entering data into cells, summing up, calculations,etc...)
once you are done, display the macro and you will find all the needful information regarding what metohds are to be called and how...

Is it possible to call ms-dos command in abap program?

Hi,
is it possible to call ms-dos command in abap program?
Thanks.

Hi Cemil,
You probably have your answer here:
[Re: DOS/Windows command in app server;
You create your external command with SM69 (you can test it with SM49).
Then you call this command with function module "SXPG_COMMAND_EXECUTE".
(See function group SXPT for all the calls to external commands).

How to avoid time out error in abap program

How to avoid time out error in abap program
based on performance wise i want please help

Timeout occurs when a statement exceeds its time limit.To avoid this we need to tune the statements.
I can give give you few tips for tune a select stament.
1.The order of the feilds in the select statement should be same as the order of fields in the database table.
2.It is always advisible to use the key fields when you are using the where clause.
3. Sort the internal table while using the for all entreis statements.
4.Use index in where clause if necessary.
5.When you have a read statement user binary search but before this a sort statement should be there.
6. Check your program with the Tcode ST05 and check which statement takes much time based on that tune that.

How to call a labview dll from excel-VBA?

How to call a simple Labview DLL from Excel VBA?
I have seen examples of DLL calls from VB but does it work the same way for VBA? I have 2000 excel and Labview 8.5. I created the DLL and tried to call it from VBA using the same type of code as in NI's website example(ofcourse its a bit diff with 8.5)
http://zone.ni.com/devzone/cda/tut/p/id/...
BUT it errors out when called from excel
ERROR: The object invoked has disconnected from its client

You would need to provide more details about the LabVIEW DLL, such as the prototypes of the functions (VIs) that you're trying to call, and your actual VBA code. Specifically, what object you're trying to create. You should also make sure the Run-Time Enginer is installed, as well as any required libraries such as the VISA Run-Time if you're using VISA. Have you made sure to enable the ActiveX server for the DLL?
