Powerbuilder Datawindow Retrieve
I would like to create a dynamic datawindow retrieve. I have a list of datawindows with various types of retrieval arguments--some are arrays. I would like to pass a program the parameter and parameter type and have it dynamically build the retrieve. I've tried using the ANY variable type, but it doesn't work when the argument is an array. Does any one know of a way to "build" the retrieve statement on the fly, or something else to do?

This might help you. When you are using array as a retrival argument, then you have use 'in' instead of '='. In the retrieve, you must be specifying dept.dept_id = :adept instead of that you have to specify dept.dept_id in :adept when adept is an array.

Thanks for all who helped. Your suggestions triggered an idea and I found a
way to build the retrieve:
--------------
// This is only part of the code, but it should be enough to show what
// I did.
INTEGER i_Counter = 0
ANY any_p[1 to 5], any_TmpArray[]
STRING as_Param, as_ParamType
....some code
DO
i_Counter += 1
as_Param = ???? // Some how fill this
as_ParamType = ???
CHOOSE CASE UPPER(as_ParamType)
CASE 'NUMBER'
any_p[i_Counter] = DEC(as_Param)
CASE 'NUMBER ARRAY'
// Fill a temporary array
// .....
any_p[i_Counter] = any_TmpArray
CASE "DATE"
any_p[i_Counter] = DATE(s_Param)
....etc
END CHOOSE
LOOP UNTIL s_Param = '' OR i_Counter >= 5
dw_1.retrieve(any_p[1], any_p[2], any_p[3], any_p[4], any_p[5])
----------------
Hope this helps someone.

Powerbuilder Datawindow
Hello, Can you do a Datawindow in VS 2005 without using Datawindow.NET just by using common controls i.e DataGrid etc. Thanks Chris What would you use the DataWindow for then? To retieve the datawindow into a datastore and then attempt to use it to populate the DataGrid? I've heard of people who want to have their cake and eat it too, but it sounds like you want no cake but you want to eat it...

Powerbuilder datawindow
Hi! I'm importing a some data into my application. The way I do this is to insert a the rows into a datawindow and then do an update() on the datawindow. If a row in the database allready exists with the same primary key as I have inserted into the datawindow, what will happen then? Will then datawindow do an update or will I get an error? I'm doing this on a datastore object. How can I get an errormessage from the datastore? I have tried the errormessages and codes from the transaction object (sqlca.sqlerrtext and sqlca.sqlcode).

Powerbuilder API call to stop datawindow retrieval
When I used SQLNET v1.x with Powerbuilder v4.x, I was able to stop a datawindow retrieve in my apps with a key combination of <CTRL>-<C>. This was a very nice feature to have, especially, with a datawindow retrieval lasting several minutes. With Powerbuilder v5.0.0.3 and SQLNET v2.0, the <CTRL>-<C> feature does not work. Powersoft tech support says that Oracle SQLNET v2.0 does not support this feature. But, SQLNET v2.0 documentation says that it does support this feature. I tested this successfully via SQLPLUS.

Powerbuilder Datawindow Retrieve is unusually slow. What's wrong?
We are using powerbuilder with Sybase SQL Anywhere 5.5. An issue we are having is that datawindows that have records 10000+ slow down almost exponentially during a retrieve the higher amount of records there is. A 40000 record datawindow should not take 5-10 minutes to retrieve on a 1ghz machine. Have any of you experienced a similar problem? Please let me know any suggestions you have.

PowerBuilder Datawindow Bug
Folks, I just wanted to follow up with the work-arround I did on a PowerBuilder 8.0.3.9704 and SQL Server 2000 (latest patch) bug. The bug lies in the MSS database driver. Basically PowerBuilder truncates any string comprosed entirely of spaces to the empty string as it retrieves from the database to the datawindow. The solution for me was to wrap any candidate column with this scenario with a non-blank string (I used the string '##'), and then after datawindow retrieve, loop through datawindow, and remove the string from each side of the queried columns. Tons of overh...

Printing a Datawindow in PowerBuilder
I have some problems properly printing a datawindow in PowerBuilder. When I print a document the printer will print the top half of the ast line on the third and bottom half of the line on the fourt page. In my datawindow I only have aboout four fields but the last one is a SQL Server "TEXT" field, so this field can store many pages of information. In the PowerBuilder Data Window I have the field set to auto size height. Another thing I have noticed that it prints differently on different computers, meaning it may print fine on one computer and not on another. S...
PowerBuilder and Power++ Datawindows
We are still maintaining an old Power++ based application, which makes quite extensive use of DataWindows. Since using the DataWindows with a MS SQL Server 2005 (a customer requirement), we are looking for a solution where we can use the old Power++ SW with a more recent DataWindows implementation. Is this possible at all with PowerBuilder? Are we able to import or migrate the already existing *.pbl/*.pbd files? Os is DataWindows.NET a more feasible solution?

PowerBuilder down on opening a datawindow.
I'm using PowerBuilder 9.0.1 on Windows XP and Oracle9i. Suddenly I cannot open any datawindow. Each time I tried to open datawindow with datawindow painter, PowerBulider gets down. Someone told me that changing default printer might help. But it didn't help. Please help me. Thanks. Several suggestions: First make a backup of the datawindow to another .pbl (you may even want to create a new .pbl just to hold the backup). 1) Try regenerating just the datawindow. 2) Try optimizing your .pbls then a full regeneration (back up all the .pbls first, again just as a ...

Does anyone have experience re-using DataWindows from an existing Powerbuilder App. in DataWindow.NET? It would seem possible from the documentation.
