I was thinking of taking another look at palm programming. Palm.com has been fairly helpful, but does anyone have a simple program that they could show me? I can't find actual code anywhere

[SteveCRM]

I've almost got it, but I can't find a list of functions available...I can do stuff in C, but can't figure out stuff like setting text to controls and stuff...thanks all!

I don't have the link any more.......but look up "Windows eMbedded Visual C++" on microsoft website. You can download the Visual C++ for Windows CE program for free and it gives samples and a free sdk with it.

I hope that is what you want?

Im looking for PalmOS..but thanks

I have a compiler, (falch.net) but now I just need some functions to modify controls, set output, get input...etc

I've found some, but they confuse me to hell!

I've forgotten where to find out about Palm stuff (been a while since I looked into it) but there are a couple of major windowing systems around for PalmOS. You might want to search for them.

Not really that helpful I know, but it's the best I can do.

I've found out how to set labels....but I don't understand how to get text...I've seen functions like FldGetTextHandle and FldGetTextPrt

don't understand the explanations though

FldGetTextHandle
Purpose

Return a handle to the block that contains the text string of a field.
Prototype
MemHandle FldGetTextHandle (const FieldType* fldP)
Parameters
-> fldP
Pointer to a field object (FieldType structure).


Result

Returns the handle to the text string of a field or NULL if no handle has been allocated for the field pointer.
Comments

The handle returned by this function is not necessarily the handle to the start of the string. If you've used FldSetText to set the field's text to a string that is part of a database record, the text handle points to the start of that record. You'll need to compute the offset from the start of the record to the start of the string. You can either store the offset that you passed to FldSetText or you can compute the offset by performing pointer arithmetic on the pointer you get by locking this handle and the pointer returned by FldGetTextPtr.

If you are obtaining the text handle so that you can edit the field's text, you must remove the handle from the field before you do so. If you change the text while it is being used by a field, the field's internal structures specifying the text length, allocated size, and word wrapping information can become out of sync. To avoid this problem, remove the text handle from the field, change the text, and then set the field's text handle again. For example:

/* Get the handle for the string and unlock */

/* it by removing it from the field. */
textH = FldGetTextHandle(fldP);
FldSetTextHandle (fldP, NULL);

/* Insert code that modifies the string here.*/
/* The basic steps are: */
/* resize the chunk if necessary,*/
/* lock the chunk, write to it, and then */
/* unlock the chunk. If the text is in a */
/* database record, use Data Manager calls. */

/* Update the text in the field. */
FldSetTextHandle (fldP, textH);
FldDrawField(fldP);
