I am using Delphi 7 Enterprise on Windows Vesta. I created a number of units with their own forms. The main form suddenly is not visible and I cannot make it visible using the normal tool of clicking on the list of forms. The information on the form clearly still exists as does the DFM file. I cannot run the program to see if the form appears because I sill have compilations errors. The main compilation errors is Duplicated Resources, as follows:
[Error] WARNING. Duplicate resource(s):
[Error] Type 10 (RCDATA), ID TSEARCHFORM:
[Error] File SearchUnit.dfm resource kept; file SearchUnit.dfm resource discarded.
[Error] Type 10 (RCDATA), ID TSEARCHFORM:
[Error] File SearchUnit.dfm resource kept; file SearchUnit.dfm resource discarded.
I do not know if these problems are separate problems . Either way I seeking solutions for both of them.
I have no experience at all of resolving Duplicate resources and I m at a loss as to where to start finding the problem. I also have not met the problem of having my Form becoming invisible ( since Object inspector cannot see it either).

Thank you for your quick response. I searched all files for {$I *.dfm} but nothing was found. I searched for {$I and also found nothing. on searching for .dfm I found two {$R *.dfm}. If I delete either of them I get a compilation error in the system Forms units. Any further help will welcomed
Regards
Sorry, I meant {$R, not {$I. My mistake.
You need a {$R *.dfm} for each Form that you want to use. You cannot just delete them.
The problem is in your uses clause. Check it to see whether you have a file included there that has {$R *.dfm} and referers to the form by the same name. (Searching through Project Files is not going to help you. This typically occurs due to a residual file that was in your project earlier, and you removed -or renamed- afterwards)
Thanks. The duplication error has gone.
Can you please shed any light on how the main form has disappeared (a separate form from the SearchUnit.dfm that caused the duplication error).
I get the error 'Resource TForm1 not found'. Although its details and published contents exists and its dfm file exists. Is there a pointer to where the form location should be?

You have at least two include statements {$I *.dfm} that have forms of the same name. Do a "Find in files" for {$I and delete the duplicate.
Mostly what has happended is that you renamed "SearchUnit.pas" from a different name, but still have the original in the uses clause.
