ColdFusion Tips:

Have you ever had your CF program throw you this error?....

Error Diagnostic Information Just in time compilation error Invalid token found on line 497 at position 3. ColdFusion was looking at the following text:

Dont bother looking at Line 497; ColdFusion is BSing you, and it really doesn't know where the problem is. However WE do...
I've found (by painful experience) that the problem is USUALLY a missing close bracket > on a line JUST previous to that.

Look for an HTML or ColdFusion tag that you forgot to close on the few lines preceding that line.

How to find out the title bar text of the Active Window:

FUNCTION ActWinText
DECLARE Integer GetForegroundWindow in win32api
DECLARE Integer GetWindowTextLength IN WIN32API Integer nWnd
DECLARE Integer GetWindowText  IN WIN32API Integer nhWnd, String @cString, Integer nMaxCount
hforewnd = GetForegroundWindow()                    && determine the foreground window
slength = GetWindowTextLength(hforewnd) + 1         && length of its title bar text
wintext = REPLICATE( CHR(0), slength )              && make room in the buffer to receive the text
retval = GetWindowText(hforewnd, @wintext, slength) && get title bar text
wintext = Left(wintext, slength - 1)                && remove null character from end of string
RETURN wintext

How to insert a combo box into a grid control: Microsoft's Method (lacks details)

My Method - derived from http://www.iinet.net.au/foxpro/_foxy15.html

Q. How do I replace the default textbox in a grid with a different class?

1. set up the grid the way you want to see it, with textboxes instead of the Combo Boxes. Get everything sized, etc.
2. Right click on the grid and select "Edit" from the popup menu.
3. Click on the header (title) of the column into which you want the Combo Box placed. The grid will flash for a moment.
4. Click on the Combo Box button on the toolbar.
5. Click on the grid _underneath_ the header, you clicked on before, to insert the Combo Box into the grid. The grid will flash again.
6. Right click on the grid and select properties from the menu.
7. Pull down the list box at the top of the properties sheet, and scroll down to the "Column#" entry where you inserted the Combo Box.
8. Click on the Data tab, then change the CurrentControl from "Text1" to "Combo1".

If you place the combo box on the form first, you can use the builder to set the combo box up. Then you can mark it, do an EDIT / COPY, and paste that already set-up combo box INTO the grid using SHIFT INSERT, in place of step 4 above (it DOES work, trust me...)

I've been developing in Clipper since 1990, at Paradyne Corporation. You can look at my resume to see what I've done in the past, but I actually do very little work in Clipper now, since my efforts have been focussed on Visual FoxPro and ColdFusion applications.
