Data type conversion problem

Hi all;

I have a form and it contains only a textbox and a command button. I ask user to enter a date into the textbx then press the button.

After that I want to filter G/L Entry table by this date with the following line;

SETRANGE("Posting Date", CurrForm.txtPostingDate);

I wrote it down into command OnPush trigger of the button.

When I try to compile I get the following error :
Type conversion is not possible because 1 of the operators contains an invalid type

Date:=Control

I see the meaning of the error. But how can I compare or match a table field with the value of a form control?

Thanks so much.

    You declare a global variable of type Date. Then you bind the textbox to the variable using Source Expression from the properties of the control. Finally:


    glEntry.SETRANGE("Posting Date",MyGlobalTextVariable);

    To elaborate a little.... you use "CurrForm.txtPostingDate" as the parameter for your SETRANGE, which it looks like is the name that you gave to the textbox. The textbox itself is not a datatype, it's a control on the form. It must have a variable as its SourceExpr. If you use the variable in your SETRANGE statement, you should be alright.

    You can use a data type 'Date' but that won't allow you to enter a datefilter. I would probably use a text type variable if I needed to be able to enter filters instead of single date values.

    Rather use the Date type variable instead text variable... ;-)

    If you want to enter a date formula into the textbox, a date type variable is not enough.

    Yes, but it was not specified, Soloper is talking about date. In case of filter, text is ok, but I will use SETFILTER instead SETRANGE... 8)

    Right if they need a single date only, then I would also use a date type variable, and SETRANGE.

    I have a type conversion problem. i got a report sent from my head office.... it is a label printing report... when i imported and tried to compile, am getting type conversion error.

    Type conversion is not possible because 1 of the operators contains an invalid type.

    Text := VOID
    OK



    In that there is a coding line which is given below

    Addr[1][1] := PrintBarCode.ParseRequest(ICR."Cross-Reference No.");

    when I try to compile it throws the error and the cursor blink at this code only.


    ADDR[1][1]is defined as text[250].

    Printbarcode ====> NAv Comm (Codeuint)

    there the cross reference no. is passed and get converted into barcode number....


    can any body tell what is need to be done.....

    You should post this as a new topic. The original one is closed...

    The Addr[1][1] looks suspicious.

    How is it declared? Have you tried Addr[1,1]?
