Error trying to create dialog:

billtubbs · Post by **billtubbs** » Wed Apr 18, 2007 6:10 pm

I am using a dialog box for the first time. The problem only occurs when I put the dialog definition within a loop. It executes fine the first time, the second time around the loop I get the following error message:

"Error trying to create dialog: MyDialog"

In the help on Dialogs there is nothing about where in the code to put the definition code for the Dialog. Should it be in the loop (dialog is redefined each time) or before the loop (only executes once). The error does not occur if I put the dialog definition before the loop. However I want the label text to be different each time, and this does not occur if the dialog code is outside of the loop.

Here is the code:

Code: Select all

Dialog>MyDialog
Caption=Macro scheduler
Max=0
Min=0
Close=0
Resize=0
Left=300
Top=300
Width=200
Height=100
Label=Run reference case simulation for %CRLF%%CountryName% model?,5,5
Button=Yes,10,40,50,20,1
Button=No,70,40,50,20,2
Button=Exit,130,40,50,20,3
EndDialog>MyDialog

Show>MyDialog,result
If>result=3,Stop
If>result=2,SkipRefRun

Anybody know how to avoid the error but have different text in the dialog each time it is displayed? Is there a way to pass a string to a dialog box?

Don't put the dialog definition inside the loop. The dialog can only be created once. It can be SHOWN many times, but created once. The dialog block should therefore appear before your loop.

Thanks, I figured that. It might be worth explaining this on the dialog reference page.

So does this mean all dialogs static? You can't have the same dialog show different label text and you can't pass variables to a dialog?

No dialogs are not static, you can change captions and values at runtime.

Bill,
Here's a simple dialog that updates. It is a button that updates but the concept is the same for labels.

Code: Select all

GetTime>ttime
ScreenCapture>-1000,-1000,-888,-888,%TEMP_DIR%~~WhiteSpace.jpg
Dialog>MyDialog
   Caption=           Time
   Width=112
   Height=60
   Top=CENTER
   Left=CENTER
   Max=0
   Min=0
   Close=0
   Resize=0
   Image=%TEMP_DIR%~~WhiteSpace.jpg,0,0,112,60
   Button=ttime,14,6,75,25,2
EndDialog>MyDialog

Show>MyDialog
IfFileExists>%TEMP_DIR%~~WhiteSpace.jpg
  DeleteFile>%TEMP_DIR%~~WhiteSpace.jpg
EndIf

Label>start
  GetDialogAction>MyDialog,r
  If>r=2,End
  GetTime>ttime
  Let>MyDialog.MSBUTTON1=%ttime%
  ResetDialogAction>MyDialog
  Wait>0.1
Goto>start

Label>End
