Hi All,

I made two custom dialogs in isuser and I want to call them one by one in the OnBegin() function. I used the code given in Installshield help to call a custom dialog. But if I repeat the same code for the other within the same function (or in other function ... doesnt really matter), it gives me the error "multiple case labels for statement". Even if I change the ID for 'Next','Back' or 'Cancel' button and use these new IDs as test cases, it gives me the same error.

Has anyone worked on multiple custom dialog boxes before ? I know the code works if you have just one custom dialog box. Any help would be appreciated.

Thanx
DK

I haven't had to use more than one custom dialog, so I'm not talking from experience here. Have you properly released all the resources you're using for the 1st box before you're attempting to reuse them for the 2nd?

If you post the code from your OnBegin function it might be easier to see what's going on.

Is this a compile time or a run time error?
If compile time: on which line?
If run time: use the debugger to see on which line.

Hi,

Here is the code I have written. The two custom dialogs are DLG_CONFIG and DLG_COFFEE

#define DLG_CONFIG 13032
#define IDC_SRSCNTRL_PORT 1004
#define IDC_SRSCORE_SERVER 1005
#define IDC_SRSCORE_PORT 1006
#define IDC_SRSCORE_TIMEOUT 1007

#define DLG_COFFEE 3
#define IDC_CREAM 1001
#define IDC_SUGAR 1002
#define SD_PBUT_COFFEE_CONTINUE 1009
#define SD_PBUT_COFFEE_BACK 1010
#define SD_PBUT_COFFEE_CANCEL 1011

function OnBegin()

STRING szDialogName, szString, szDesc, szTemp, szMsg, szDirPath;
NUMBER nResult, nCmdValue, nvFileHandle;
BOOL bDone;
HWND hwndDlg;


begin

// Specify a name to identify the custom dialog in this setup.
szDialogName = "MyConfigDialog";

// Define the dialog. Pass a null string in the second parameter
// to get the dialog from_isuser.dll or _isres.dll. Pass a null
// string in the third parameter because the dialog is identified
// by its ID in the fourth parameter.
nResult = EzDefineDialog (szDialogName, "", "", DLG_CONFIG);

if (nResult < 0) then

// Report an error; then terminate.
MessageBox ("Error in defining dialog", SEVERE);
abort;

endif;

// Loop until done.

repeat
// Display the dialog and return the next dialog event.
nCmdValue = WaitOnDialog (szDialogName);

// Respond to the event.

case IDCANCEL:

// The user clicked the window's close button.
Do (EXIT);

// Set the message that appears at the top of the dialog.
//szDesc = "Specify options to be written in the Config file " + "\nThen press Next to continue.";

Its a compile time error at line

case SD_PBUT_COFFEE_BACK:

Your empty case DLG_INIT: may be cauing the problem:
