Hello all,
I am creating a report generation program with VB 6.0 as front-end and Oracle 10i as back-end. My reqiurements are
1. User will query the database through the front-end.
2. The results will get populated in an MSHFlexGrid.
3. There will be a button at the bottom captioning "Export to excel" clicking which shoud generate an excel file with the data contained in the grid.
4. User must not be able to copy the data from the generated file. He should be able to see it without any passwords etc. being asked.
So, to solve the above problems, I have made a VB program. I have successfully achieved the first three objectives. For the requirement number four, I am using the following code: -
wksReport.Protect "something_secret"
-
wksReport.EnableSelection = xlNoSelection
The above code does protect the sheet and does not allow the user to select any cells. After that I am closing the workbook and here comes the problem into picture.
Actually when I am reopening the file (not programatically , just by double clicking the file), the sheet still is protected but user can very easily select the cells and copy them to a new sheet, thereby defeating the purpose of security and requirement number four.
My doubt is that the EnableSelection property is not persisting when the file is closed and is set to its default value when the file is reopened.
Kindly throw some light on this.
Thanks in anticipation.

I don't know much about it, but I have one question. When you refer to "closing" the file after setting the protection - are you saving it?

Hi,
Not sure of this , but the coding Sequence should be in reverse order (Check Excel Help): -
wksReport.EnableSelection = xlNoSelection
-
wksReport.Protect "something_secret"
-
and as Killer said, dont forget to save the sheet before quitting..
Regards
Veena
I am definitely saving the file before closing it.
Also, I have tried it both the ways, i.e., first protect then setting EnableSelection property and vice-versa. Actually it doesn't matter what you do first beacuse I am anyway saving the file before closing it. So every operation on the workbook should get saved.
Any other expert can show me the way???
Is anybody there to help me out on this?
Ahah! Pretty sure I found your answer. MS acknowledge the problem, and have a workaround, though not really a solution.
See Some of the properties of worksheets are not preserved in Excel
I read the article and got your point. But now, is there any other way to achieve my requirement number four.
I cann't put macros in programatically generated excel files beacuse they are hundreds in number and also many people keep macros disabled for security reasons.

With MS effectively throwing up their hands in defeat, I don't see how it could be done. I only glanced at the article - there was no patch or anything?
The only other alternatives I can think of are... - Use a different spreadsheet program instead of Excel.
- Display the data in your own program, rather than using spreadsheet.
- Use your program to drive Excel for display purposes, and do what the macro might not be able to do.

All of your alternatives are useless for me as my client requirements are fixed and have been mutually agreed between us months back. It will be something like taking up the challenge and then stepping backward saying that I didn't know that it is not possible using Microsoft Technologies.

Instead of saying "useless",
How about using some good words like "Does not fulfill my requirement"... ?
when some one is trying to help you out be generous in action..

Code for opening the form is

Can anyone tell me what might be causing it to "hide" itself until the

Hi All,
We have a busy website, and I was wondering if we should persist the
data by storing the data table in a session or cookie, and when the
user re-loads the page I can cast the session or cookie back to a
datatable and rebind to the grid.
This is a closed web system so there is no problem getting users to
make sure cookies & javascript is enabled.
