问题 I cannot interpret the value from the Barcode Scanner from Power Builder. I am seeing from Key event, the value of Key seems to be "KeyEscape!" and hence it closes the window. Is there any syntax which gets the value from the Barcode Scanner in the keyevent ? But when i use notepad, it is showing some value like "b000012300 " and the space represents KeyEscape! Is there a way to interpret this value in power builder ? Please help me. 回答1: The cancel property for a CommandButton ,

问题 How to view arabic characters correctly in Sybase PowerBuilder 6 or 7 as I use Arial(Arabic) or any arabic language in the properties of the table and the database but it shows the characters as strange symbols that has no meaning like ÓíÇÑÉ ÕÛíÑÉ ? 回答1: I'm no expert in dealing with Arabic language characters, so there may be a work around with ANSI code pages, but I'd expect your best solution is Unicode. There was a distinct version of PB6 supporting Unicode (i.e. a separate product), but

问题 Does anyone know if Powerbuilder 10 is compatible with Windows 8 (Both the IDE and the runtime module)? It seems like 11.5 is officially supported, but I couldn't find any info on PB 10's compatibility on Windows 8. If it isn't, any tips on the migration process from 10->Further version? (Anything particular we have to watch out for?) 回答1: You should have no problem with running PB10 applications on Windows 8, appart perhaps not being not fully compliant with Win8 standards (concerning the

问题 I want to be able to check the return code from an application that is executed. I tried implement it by the PowerBuilder function Run, but its not return the code of application which executed. Thanks. 回答1: In fact, Run() launches the target synchronously, so by the time the next line of PowerScript runs, your Run() app may not be finished, let alone have a return code available. You need to make the Windows API calls with appropriate parameters yourself to achieve this, instead of relying

问题 Can anybody help me that how can I protect individual column of an individual row, though my datawindow has more than one row. I am writing a code like this: dw_1.Modify("column_name.protect = '1'") However it is making all my rows disabled. 回答1: You need to have some sort of conditional statement for the particular row/column you wish to protect. One way is to have an additional field you set programatically like. dw_1.setitem(1,"protect_me","Y") Then in your other column you set an

问题 Where it says "blob_curr = 1" I need to do a check to see if the object id exists in another table. I have no idea how to do this. This is an application that was written several years ago and I am a co-op student who was asked to make some changes to it so I have very limited knowledge of this environment. This is Powerbuilder 9.0 if that helps. 回答1: You have two options here: 1) You can update your datawindow query to include an additional field that returns whether the item exists in the

问题 In Powerbuilder, Does anyone here know how am i going to highlights multiple items on a treeview? Selecteditem function is not doing that. Im looking for a behavior just what Selectedrow id doing.

If not, I found this on the newsgroup, don't know if it helps: The following script in the selectionchanged
