Instantiating an Excel Object from Peoplesoft page

Using the example from PeopleBooks returns an error on the ObjectGetProperty statement and I don't know what is wrong with it.
The code used is as follows:

Local object &WorkApp, &WorkBook;

&WorkApp = CreateObject ("COM", "Excel.Application");
&WorkBook = ObjectGetProperty(&WorkApp, "Workbooks");

etc
The message returned for the ObjectGetProperty statement says "Invalid parameter: CreateObject Excel.Application invalid class string for function ObjectGetProperty. The specified parameter is not correct for the function. It may be the wrong type of parameter (string, number, record, field etc) or an invalid value in this context.

Can anyone help?

Should the variable &WorkBook be delcared as an object? If you change the delcaration line to:

 Local object &WorkApp;

And remove, &WorkBook, does that make any difference?

Hi,

I have instantiated Excel Object in AE Peoplecode and have been successfully manipulating data cells in each worksheet tab of my workbook.
Now I want to copy a range of cells from one worksheet to another and paste its values on the other worksheet, though I dont encounter error but the
action does not execute. Also when I try to save the excel file it takes forever to save. Heres some part of my code
Appreciate your input.

get a cell range then;

&RangeSelected = &oCells.Copy;
&oWorkSheet1 = &oWorkApp.Worksheets("Sheet2");
&oCell = ObjectGetProperty(&oWorkSheet1, "Range", "A1");
&SheetSelected = &oWorkSheet1.Activate;
&oCell = ObjectGetProperty(&oCell, "PasteSpecial");

ObjectDoMethod(&WORKAPP, "Save", "C:\TEMP\TEST1.XLS");

Thanks a lot

Hi Susan, I use the same code and it works fine. Only thing I notice in your code is that you have space between createObject and the parenthesis

Heres our code compare side by side
&WorkApp = CreateObject ("COM", "Excel.Application"); your code
&oWorkApp = CreateObject("COM", "Excel.Application"); my code

&oWorkBook = ObjectGetProperty(&oWorkApp, "Workbooks"); my coode
&WorkBook = ObjectGetProperty(&WorkApp, "Workbooks"); your code

I hope it helps..

Yes its should be declare as Object when instantiating workbook, worksheet, range or cell objects in Excel heres my declaration and it works fine;

Local object &oWorkApp, &oWorkSheet, &oWorkBook, &oRange, &oCells;

Hi - I have sqr process to read the .dat file as input file. But I am getting the file in excel format. I want to convert this XLS file into .dat format. I am unable to do this through the SQR. One of my colleague suggest me go with the Application Engine. Here is the code I am trying to convert the XLS file into .DAT through the App Engine. But I am missing the link between after opening the xls file and writing into .DAT file. Can you help me how to connect between after opening the file and writing the file.

&oWorkApp = CreateObject("COM", "Excel.Application");
ObjectSetProperty(&oWorkApp, "Visible", True);
&oWorkBook = ObjectGetProperty(&oWorkApp, "Workbooks");
&oWorkBook.Open("C:\temp\rates99.xls");

Local File &DATFILE;
Local string &FILE_NAME, &DATA;

&FILE_NAME = "C:\temp\rates.dat";
&DATFILE = GetFile(&FILE_NAME, "r");
&FileName = &DATFILE.Name;
&POS = Find(".", &FileName);
&NEWFILE_NAME = Substring(&FileName, 1, &POS) | "dat";
&DATFILE = GetFile(&NEWFILE_NAME, "N", %FilePath_Absolute);
If &DATFILE.IsOpen Then
While &DATFILE.ReadLine(&DATA);
&DATFILE.WriteLine(&DATA);
End-While;
&DATFILE.Close();
End-If;

Hello Susan,

Are you still having the same error "Invalid parameter: CreateObject Excel.Application invalid class string for function ObjectGetProperty." ? What have you done to correct this error?
I am actually facing the same error when using the following code in my AE peoplecode:
Local object &oWorkApp,&oWorkBook;
&oWorkApp = CreateObject("COM", "Excel.Application");
&oWorkBook = ObjectGetProperty(&oWorkApp, "Workbooks");

Thank you for your help.

Hi,

I want to use this piece of code on my page on the hyperlink.

Local object &oWorkApp, &oWorkBook;
&oWorkApp = CreateObject("COM", "Excel.Application");
&oWorkApp.DisplayAlerts = "False";
&oWorkBook = ObjectGetProperty(&oWorkApp, "Workbooks");
&oWorkBook.Open("C:\some_path_to\template.xls");
&oWorkSheet = &oWorkApp.Worksheets("Sheet1");
&oWorkApp.ActiveWorkBook.SaveAs("C:\your_output_file.xls");

But when I click on the link it gives me the error 'Class COM not found. The given class is not found in the database or having problems to access it.'

Please help.

Looks like the &oWorkApp object is not being instantiated properly, has that object been declared in your code?

I tried your code, and it works fine for me - for some reason it isn't picking up the Excel.Application COM object. Which version of PeopleTools are you on?

As per other posts, looks like the following line:

 &oWorkApp = CreateObject("COM", "Excel.Application");

Is not working, which PeopleTools version are you running?

Hi,

The pre/requisite to use Excel API class is are:
1) Should be run in a windows env. Hence the batch server should be windows, in Unix these commands will not work
2) MS Excel should be installed in the windows machine. If not, then calling createobject for Excel application will throw exceptions since there is no underlying excel libraries to handle the call.

To test your AE works or not, you can try running AE in 2 tier i.e directly from Application designer assuming your work env machine is windows with excel installed. The code should work properly there.
