    Saving record makes dataset point to first record ???

    I am using Paradox Level 7 tables with the Native BDE Paradox drivers. I have noticed that after saving a record (I am actually using ApplyUpdates on cached updates thru a transaction) the dataset record pointer repositions itself on the first record. This makes it necessary for me to reposition...

    precision and TFloatField

    I'm having trouble with a numeric value displaying in scientific notation in a grid field. The required maximum enter and display width for the grid field is 20 chars. It looks like TFloatField.Precision defaults to 15. I think because of this whenever you enter a number in the grid that has...

    sharing violation when attempting to delete folder

    I changed the current directory, then removed the one I wanted to delete, but this did not work. There is still a sharing violation. This folder I want to delete is a subdirectory that has been created by the app under the app's main dir. Is there a way that I can force a delete of this folder...

    sharing violation when attempting to delete folder

    I have a program that creates a new folder and copies paradox files into the folder when you create a new "office". This all works great. However, when I delete an "office", I am unable to delete the folder. All of the files within the folder were deleted without an problems...

    TTable.FindKey blow up

    Finally found the problem with my FindKey exception. There was nothing wrong with the code at all. Someone who had worked on the same project years before said that they had encountered a similar problem, and he finally decided to remove the dataset component from the form and re-add it. That...

    TTable.FindKey blow up

    Would the {$I+}, {$I-} compiler switch have any affect on TTable.FindKey? I noticed this in the code of my project in a routine where there was no other file I/O going on, but there was a FindKey, in fact the FindKey came immediately after it. (I didn't put it there; I inherited this project :=)

    TTable.FindKey blow up

    I tried to use Locate instead of FindKey, and I got the same error. It actually worked fine on my dev machine; again, it did not work on test machines.

    TTable.FindKey blow up

    I've tried all those things, except the Locate. I will definitely try the Locate.

    TTable.FindKey blow up

    I am getting an exception on a FindKey call. The error states that the name of my primary key must have a value ('Field "ID" must have a value'). This seems to only happen when the dataset is empty. Now, this dataset is in a shared data module. The error occurs after a form with a...

    invalid blob handle in record buffer error

    I don't have any fields that contain more than 255 characters. But I think I may have found a solution. The tables that I was using were of mixed Paradox levels; some level 4, some 5, some 7. Since it is a single-user local database application meant only to run on 32-bit windows, I made sure...

    invalid blob handle in record buffer error

    Numerous times I have received an error stated as "Invalid BLOB handle in record buffer" when attempting to update tables. I am not even using BLOBs in this project at all. The error is very inconsistent, or at least I have difficulty duplicating it. I am using transactions through...

    check box value from screen

    The check box is initialized before launching the screen and has not been declared PUBLIC or PRIVATE. All other screen control variables were declared and initialized the same way, and they work fine. Thanks

    check box value from screen

    I am using FoxPro 2.6. I have a screen that includes a check box on it. I am initializing the associated variable before I launch the screen, but if I select the check box and hit my OK button to exit the screen, the variable's value does not change. In the code it will stay whatever I init it...
