My Little Grid updated to Version 1.08 - Workbooks

[james klutho]

I just uploaded updates of My Little Grid (Version 1.08) to my website.

The big news here is the addition of Workbooks and individual cell formatting. The programmer is allowed 255 separate sheets (freeware version just 3 sheets) which can all have their own grid size. This is perfect for loading multiple tables of a database into one grid. The Workbook has an Excel flavor to it which should make its response intuitive. Tabs can be colored and moved.

Also numeric fields can be displayed in very flexible formats (using Powerbasic's FORMAT$ function)

Version 1.08 also introduces Format Overriding which allows some formatting to the individual cell level. This may be handy in making one sheet a reporting sheet off the other sheets in the workbook.

Attached is a thumbnail screen shot of a workbook along with a working example of some of the new features. The Total sheet is a read only sheet which calculates sums from other sheets. This has a hint of a spreadsheet in it.

My Little Grid comes in two versions. The demo version is freeware which allows for 26 columns and 5000 rows in grid. This may be all many of the users need so feel free to use this version as you wish. The purchased version allows for 256 columns and 2,000,000,000 rows and only costs $35.

My Little Grid is meant to be an easy to use, basic grid with databases in mind. With Workbooks, it is now an unbelievable value. Please take it for a spin around the block. If you are a paid user, grab the zip file password and have fun with this new version.

Hi Jim,

Do you have a PayPal account that I can transfer the funds to for the purchase?

[Chris Holbrook]

How does the licence work? If I wanted to distribute it "inside" a product?

[james klutho]

Hi Chris

You are free to distribute the dll in any product. Licensing is generous. Do as you like. I hope you find My Little Grid useful.

Regards
Jim

Just noticed that a couple of routines I use did not make it into the include file. One of them copies a selected blocks of rows to the clipboard to be pasted into Excel (visible columns only) and the other hides a selected block of columns. I upload a new demo with these additions to both the include file and the help file. If you don't feel like re-downloading the demo file, simply paste this code into your MLG_PBDLL.inc file. I think it is pretty self explanatory.
