I'm writing a find routine. I'm working on a retail application and it has
ways to find records using obvious things like the sku and the UPC code
within the application. I want the find routine to find a text string that
is imbedded within a 60 character discription - so I have to write my own
little search routine. I can't find the exact wording that explains it in
the documents but it looks like the text in strToFind is compressed and I
have to pass it to TxtGluePrepFindString to turn it into an ASCII string
that I can work with. I tried various ways of passing the variables to
TxtGluePrepFindString and they all make my program abort. Maybe someone can
tell me if I am correct about needing TxtGluePrepFindString and what I'm
doing wrong in passing variables to it.
Here is my latest attempt:
Down below is where my search routine gets called.
static DWord StarterPilotMain(Word cmd, Ptr cmdPBP, Word launchFlags)
{
Err error;
error = RomVersionCompatible (ourMinVersion, launchFlags);
if (error) return (error);
switch (cmd)
{
case sysAppLaunchCmdNormalLaunch:
error = AppStart();
if (error)
return error;
WinEraseWindow();
FrmGotoForm(MainForm);
AppEventLoop();
AppStop();
break;
--->> case sysAppLaunchCmdFind:
Search ((FindParamsType *) cmdPBP);
break;
These are the interesting parts of my search routine:
void Search (FindParamsPtr sparams){
char findstring[20];
recordnumber = sparams->recordNum & 0x0fffffff;
dbinprocess = sparams->recordNum & 0xf0000000;
// the two lines above seem to do what I want.
TxtGluePrepFindString(sparams->strToFind, findstring, sizeof(findstring) -
1);
It blows up on the above call.
