"error: cannot obtain value" when debugging

When I step into a sub all of the global and local to the sub syncfusion type variables get the message "error: cannot obtain value" in the debugger. Although I can''t see what is going on it does appear that the syncfusion variables are workign correctly as my program behaves as expected. Any idea what is going on? I''m using 4.101.0.9 and VS2003.

This only occurs after calling CalculateAll. >When I step into a sub all of the global and local to the sub syncfusion type variables get the message "error: cannot obtain value" in the debugger. > >Although I can''t see what is going on it does appear that the syncfusion variables are workign correctly as my program behaves as expected. > >Any idea what is going on? > >I''m using 4.101.0.9 and VS2003. > >

Hi Brian, I tried to reproduce the error in this sample: C:\Program Files\Syncfusion\Essential Studio\4.1.0.9\windows\Calculate.Windows\Samples\XlsFileUsingExcelRW\vb I was not able to reproduce the error in this sample. I have attached the tested screen shot from this sample.Screenshot.zip Could you please give me some more information regarding how to implement the issue in this sample. I would really appreciate it if you could provide us with the sample that exhibits this behavior. We will try analyzing it here. Thanks for choosing and using Syncfusion Products. Best Regards, Jeba.

Hi Jeba I''ve attached a couple of screenshots the first is at the call to the sub showing all is ok. The second is after F11 to step into the sub where you can see that all of the calcWB properties are displaying the error. >Hi Brian, >I tried to reproduce the error in this sample: >C:\Program Files\Syncfusion\Essential Studio\4.1.0.9\windows\Calculate.Windows\Samples\XlsFileUsingExcelRW\vb >I was not able to reproduce the error in this sample.

Hi Brian, The reason is because, either your function takes a lot of parameters, or you are calling a function that takes a lot of parameters In VS.NET, when we are debugging, if a function passes a maximum of 32 DWORDS parameters, the error will be observed., because an integer-sized bitvector is used to track the stack. Please refer this link: error: cannot obtain value while debugging Best Regards, Jeba
