    - Grid on selection? Dear All, My program need one text box and one combo box on the same column in a Grid. My program is simple like that: If column1 =A, column 2 is a text box else column2 is a column box. I have put the "InteractiveChange" event on column1( in fact, it is a combo too.) I chg. the "CurrentContre" for column2 and make some necessary eg. something "Enabled", "Visible"... That works fine for input data. But when I load the Grid (start the program again), column2 can't show properly. I set back "Sparse" to True, the (Grid) data seems to be correct. My question is that:- 1. Can I show column2 correctly (Combo) when I start the program at the beginning ? ( the condation is depend on column1) (If I first make the selection on column1, the column2 show correctly. But if I first "Click" on column2, the combo can't show, also no selection.) (I try to put the "BeforeRowColChange" event on the grid, but failed) 2. My grid allow user to add and modify data, in such case, How can I do that ? Thanks in advance, SY Tag: Binding Data Tag: 186153

    - Returning focus after scan...VFP8.0 I have 3 computers each running a VFP 8.0 application. Each computer is of the same brand running XP and each computer is using a Symbol LS1908 USB bar code scanner. On 2 of the computers when I scan the bar code, the application returns focus to the same field and awaits another scan. On the 3rd computer control does not return to the text box for another scan. Each system is running the same exe. Each system has set confirm on. What else could cause this? Thanks in advance, John Tag: Binding Data Tag: 186137

    - Bug? The arrow keys are not working properly in a grid. If rows in a grid are more than the height of a grid, that means you need to use up or down keys or mouse to move the grid. It's fine to use a mouse to control the scroll bar. But up or down arrow keys can not go through the whole range. The grid will be stopped somewhere and seems missing many records. I am using VFP 8 SP1 and tested it in 2000 and XP machines. Any ideas? TIA Tag: Binding Data Tag: 186136

    - mutex, criticalsection, threading issues??? Hi, I have an app which has as one of its components an activex control which is constantly processing data from the serial port. I need the event handler for this code to be able to interrupt anything else I'm doing so that I don't lose any data. I also have a timer which I need to run once a second and do some processing of the data. I also of course have a form with which the user can interact. Because of the serial port handler, I have the application autoyield property set to .f. My problem arises from the unfortunate need for all three of these "threads" to access some of the same data structures and objects. I'm wondering if I can use some of the Windows control structures such as critical sections mutexes or semaphores to handle this? In trying to read about them, it seems important that the various items which are competing for the resource be either in different threads or different processes (or the WaitForSingleObject() function won't wait). Can someone tell me if these components are running in different threads, and then could someone recommend which of these Windows features might be best suited to allowing short exclusive use of resources? thanks for any help, Chip Tag: Binding Data Tag: 186131

    - ODBC vs. OLEDB I have posted a comment before stating a problem I was having with VB and updatebatch method and getting the error "Row Cannot Be Located for Updating...." I have found that if I use an Update SQL statement instead though it works fine (to do this though would be a hell of alot of extra programming). It also used to work before and I think it was the change from VFP 6 to VFP 7 that brought the error. Anyway, what I'm wondering is, the VB code uses a DSN ODBC connection to VFP. I'm wondering if I use the OLEDB connection, would this make any difference? I am also wondering what the difference between ODBC and OLEDB is. Also I'm wondering if maybe moving to VFP 8 would fix this problem. Tag: Binding Data Tag: 186118

    - old annoying bug or a feature? Hi, In order to validate user's imput, I place in Valid Event of Textbox some code, wich calls a form for data lookup or entering new data in related tables. Depending on lookup results, the focus stays in the Texbox or jumps to other controls with a help of RETURN n command. This seems to be very clear and convenient, but... If in some other form, launched from Valid Event, there is a SetFocus Method - the error comes: SetFocus method can not be called within Valid Event. But SetFocus is called in other form! And what more, in a way can be several more form calls that has nothind to do with the first one, but the error comes nevertheless :( I wonder, if MS will ever fix this annoyance or it is treated like a feature?

    - VFP8 Command window - Expression builder I have recently upgraded from VFP6 to VFP8 (although at the moment I feel as if I have stepped backwards)and am not a programmer or developer in any way. XP/SP1 is the OS. Keyboard macros are much used in my hobby. Could anyone spare the time and trouble to tell me how to get rid of the expression builder that pops up as soon as the macro issues the Locate or Seek command etc. This slows up things tremendously, especially where the Locate command is used in Memo fields, by comparison with VFP6.

    - Error when trying to open class This one is driving me nutty. The problem cropped up when I tried to MODI CLASS on one of the classes in a VCX. VFP says "Error loading file - record number 73. lblReplaces <or one of its members>. Parent: Not a table". I tried deleting record 73. Same error. I packed the VCX. Same error on record 73, but now it reported the object as a grid object (the one that used to be record 74 before the pack). I use Cryptor for encryption of the data in this app and I get a "Not a table" error if I forget to load Cryptor and register the data files, so I thought it was something related to the encryption (though I had the library loaded and set up properly). So I decrypted all the data even though VFP shouldn't be attempting to open the tables when it opens this class. Unfortunately, that did not do the trick. I've checked out the label base class that record 73 is based on and it seems fine as do all of my other base classes. I'm checking the VCX for corruption, but so far I haven't turned up anything. Anybody seen this before. This happens under VFP 7 SP 1 and VFP 8 SP 1. Thanks, Russell Campbell Tag: Binding Data Tag: 186055

    - Must be an easy way to do this... Given that Adobe Acrobat 5 is installed on the PC running my VFP 6 SP5 application, and given that there is a specific PDF file sitting somewhere on the PC's hard drive, I want to gracefully print a hard copy of that PDF to the current Windows printer. I have looked through the Acrobat SDK and see the DDE calls such as FilePrintSilent but have only been able to use this by first starting up Acrobat *Reader*, establishing the DDE connection to it, then printing the desired PDF. This is very clunky and visually ugly with Reader popping up. I am extensively using Acrobat itself through OLE automation which is completely invisible to the user, but I see no way to use an Acrobat OLE object to print a hard copy of a specific PDF file. You can print a PDF file within the Acrobat application itself, but not via OLE? Seems odd. Has anyone had success with printing a hard copy of a PDF file invisibly from within VFP? Perhaps a third-party tool? -- TRW _______________________________________ My e-mail: t r w 7 @ i x . n e t c o m . c o m _______________________________________ Tag: Binding Data Tag: 186050

    - Finding the last record in a table How would you go about locating the last of one or many records for an account in a table. The table can have just one or many and the account identifier is in a memo field. The format of the account number is easy enough to find in that it will have the syntax, for example: account = 12345.00 I'm assuming I should create a logical field called last that I can then populate with .t. for last. I can open the table twice, scan (for not reviewed-explained later) , flag as last upon finding a perform a loca for the field in the second, with a continue. I can also create a reviewed field that will be set to .t. after either being hit in the scan, or located. That's as far as I get with it. -- Thank you, Louis Tag: Binding Data Tag: 186046

    - dimension array as object In Visual Basic, you can do something like this: type MyType var1 as string var2 as integer end type dim MyVar(20) as MyType I'm trying to do something similar in FoxPro. It seems like you should be able to use CreateObject('Empty'), then add the properties to it you want, then dimension an array of the object like. Something like this: MyType = CREATEOBJECT("EMPTY") ADDPROPERTY(MyType,"Var1","") ADDPROPERTY(MyType,"Var2","") DIMENSION MyVar(20) as MyType However, this doesn't dimension MyVar as MyType.

    - Finding Memory Problems Hi all, I'm trying to clean up memory problems in a somewhat involved app and looking for ways of measuring the problems. Can anyone point to maybe a white paper on finding and addressing such things? So far I've just put statements in various areas of the code that write a record to a table indicating the current memory usage (as told by SYS(1016)) at that point. This seems to be a pretty ineffective--at least at diagnosing a technique that might cause the problem. For example, I found one interval that consistently increased in memory usage by around 2600 bytes most times it executed (a few thousand). Trying to recreate the problem in an isolated setting, I put together a small prg that just did those same steps in a loop. In this case, though, the memory change was 0. I've tried adding SYS(1104) in varying locations/timings in the program, but no change to speak of occurs in any case. I had some suspicion that printing was causing it but have found little to back this (at least not with SYS(1016)) and I am somewhat restricted in my driver options. Next up is tweaking memory w/ SYS(3050), but that still will only extend the time before running out of memory. Are there better ways of pinpointing where memory leaks occur w/in an app or are these pretty much all we have? Even like shell commands? TIA, John Tag: Binding Data Tag: 185986

    - cursortoxml() and chr(13) in memos Hullo, I have a table with a memo field that contains, amongst other things, occurances of chr(10) and chr(13) . If I convert this to an XML string using CursorToXML() and then convert it back to a table using XMLToCursor() then all occurances of chr(13) are stripped from the memo. I've used the various flag settings for the two functions but the chr(13)'s are always stripped. How can I keep the carriage returns? Thanks in advance. Yours faithfully Paul S.

    - Suppressing PDF Writer screen output VFP 6 SP5 on WinXP Pro I do some PDF production in one of my VFP apps. I have no problems getting the app to use the PDF Writer printer without involving the user (using the registry setting trick). One of my routines customizes a Word file via OLE automation, then prints the result to a PDF. I'd like to suppress the little dialog that pops up while it is printing this Word doc. The one that says "Printing" at the top and shows a count of the pages being printed. I use the Windows LockWindowUpdate API call at other times to hide UI changes, but this does not work in this case. I assume this is because Word is the application originating the PDF Writer activity. Does anyone know of another way to suppress this little dialog in a situation like this? -- TRW _______________________________________ My e-mail: t r w 7 @ i x . n e t c o m . c o m _______________________________________ Tag: Binding Data Tag: 185940

Is there a way to unbind data from a form during run-
time. On loading the form, the bindcontrol property is
set to false. It then gets sets to true upon the first
action on the form. Customer wants to clear the form
entirely after an action takes place, basically unbind
the data. Going to the end of file won't work because he
wants to search on a combination of six fields.

TIA
Mark

Try using parameterized views - you can set one of the parameters to an
impossible value (or add a conditional T/F clause to the view definition)
and requery.
