    Combobox not populated with array

    I was referring to adding the REFRESH() directly after the code you use to add the items to the control.

    Combobox not populated with array

    Just a thought. I didn't read the whole thread, but if the control is completely empty, perhaps you also need to add a REFRESH(). Even with the wrong parameters for the array elements, it wouldn't be empty. You'd see numbers or even a bunch of blank lines.

    Window displaying differently outside VFP environment

    Since every user can have different screen dimensions and resolutions, it's best to design user interfaces with forms and avoid absolute screen coordinates entirely. Forms can make things quite a bit easier, but we still need to be mindful of whether they will fit on a user's screen and what...

    Window displaying differently outside VFP environment

    I agree, if it's a new project, so I assume he is trying to just maintain something written before Windows, so there are a bunch of @ SAY/GET or ? lines. As for me, I still define Windows from time to time when I want a BROWSE window or a REPORT FORM to take up a specific space.

    Window displaying differently outside VFP environment

    As a rule of thumb, I don't define windows using absolute coordinates for both dimensions, especially when they're on the screen because the FROM and TO coordinates are dependent on the font size of the screen itself. So, to ensure the window is large enough for whatever you are putting into it...

    website URL validation in a text box

    The Swiss Army Knife is definitely the better tool, by a wide margin. That said, since the original request was for a potential RegEx solution, it's potentially more than the OP needed. I've used similar approaches to validate just email addresses, where I need not know if the mailbox exists...

    website URL validation in a text box

    Valid points. I'd be more inclined to use your suggestion of IsValidURL to just confirm the formatting, but the bored developer inside of us finds it fun to build something that does more than it needs to. It's like asking an engineer to make a flathead screwdriver and they build you a Swiss...

    website URL validation in a text box

    That's probably all that's needed. If Ravi's goal was just knowing a URL is formatted correctly, the function should return true even if the domain doesn't even exist.

    website URL validation in a text box

    It's not up to me, it's up to the OP. Remember, all Ravi asked for is validating that it's a valid URL format. If that's the only criteria, even a redirected, unavailable, or Bad Gateway means the URL was formatted correctly.

    website URL validation in a text box

    ...the potential to speed it up if the URL returns a lot of data. My only suggestion is that if the main objective is knowing if the URL is good, I wouldn't return loException.Message, I'd make it a consistent value such as "* INVALID *", or simply return .T. for a 200, and .F. for any exception.

    website URL validation in a text box

    ...Here's an example that definitely works. It reads the data, and returns whatever's in it. If it's blank, there's nothing there, it will return "* INVALID URL *", or you can make it return whatever you prefer, otherwise it will return the contents of the URL (assuming the URL is supposed to...

    How to supply filename when doing SET PRINTER TO NAME "Microsoft Print to PDF"

    As I mentioned, I use XFRX these days, but as far as I know it will just follow whatever dimensions are in the report file. They have a free version, so give it a try and you may not need to explore other options. That said, I've been using XFRX for decades and it's never let me down. What...

    How to supply filename when doing SET PRINTER TO NAME "Microsoft Print to PDF"

    FoxyPreviewer is actually the easiest compared to XFRX. Basically you just call it once and it creates a bunch of objects that you don't even need to understand or use directly to get it to work. You can just call it like this: DO FOXYPREVIEWER WITH "CLEAN" REPORT FORM YourReport.Frx TO FILE...

    How to supply filename when doing SET PRINTER TO NAME "Microsoft Print to PDF"

    There are quite a few PDF libraries out there, including FoxyPreviewer and XFRX. I have paid versions of both, but the one I use in my actual projects is XFRX because it's super flexible and gives me consistent results. FoxyPreviewer is easy to implement and has a ton of features too. It it...

    List Out Missing Numbers of a Number Range

    ...mention it, you would be using a range in your query so it's still optimized for current and future values in any range. For example: SELECT * ; FROM AllValues ; WHERE BETWEEN(iValue, iMinValue, iMaxValue); AND iValue NOT in (Select iValue FROM csrValues) Technically, you can...

    List Out Missing Numbers of a Number Range

    My two cent... If this is something you will do often, you can improve the performance by creating a permanent table instead of a temporary cursor so it doesn't have to keep creating it and deleting it on the fly. The other advantage is that you can also place an index on the serial column...

    Custom class in a custom class

    I stand corrected. As I said, I only use NODEFAULT in rare circumstances, such as when I want to bypass the keypress event. As you said, we have plenty of discussion here about DODEFAULT such as the last time we talked about it here...

    Custom class in a custom class

    I've always loved and hated that part about Object Oriented Programming. Years ago I made it a point to implicitly add DODEFAULT() either at the start or end of most of my custom classes, just to be sure they fire WHEN I want them to, and I use NODEFAULT() for the handful of times I need them...

    Custom class in a custom class

    PS... I should clarify. I posted before thinking about what I said. If you want the new class to run ONLY the new code, add NODEFAULT() to the child. Otherwise, you can place DODEFAULT someplace else, such as before or after the new method code.
