Greetings all,
I hope your New Years went well.
I have written code to dynamically draw text and remove that text when the page
is changed. However after a few page changes I will get this error:
-----------------------------
TestGen (unknown version) called SysFatalAlert with the message: "MemoryMgr.c,
Line:3061, Chunk over-locked".
-----------------------------
The cause of this is the creation of the text as if I don't draw any text and
just show the dyamic textbox (also part of my program) then page turning is
fine.
At first I thought it was a glitch in using dynamic UI (lblNewLabel). So I
changed it to using winDrawChars and winEraseChars but to my surprise it still
shows up.
Here is my code:
----------------------------
if(type == labelType)
{
DBRecordLabelPtr lbP;
//FormLabelType *frmLabel;
lbP = (DBRecordLabelPtr)MemHandleLock(tbH);
/*
frmLabel = FrmNewLabel(&frm,
lastID++,lbP->Text,string2int(lbP->X),
string2int(lbP->Y), stdFont);
FrmDrawForm(frm);
*/
WinDrawChars (
lbP->Text,
strlen(lbP->Text),
string2int(lbP->X),
string2int(lbP->Y)
);
FrmSetEventHandler(frm, MainFormHandleEvent);
}
------------------------------
As you can see it is using a database to read the details for the label. My old
implementation has been commented out.
Here is how I remove the text:
-------------------------------
if(type == labelType)
{
DBRecordLabelPtr lbP;
lbP = (DBRecordLabelPtr)MemHandleLock(tbH);
WinEraseChars (
lbP->Text,
strlen(lbP->Text),
string2int(lbP->X),
string2int(lbP->Y)
);
FrmSetEventHandler(frm, MainFormHandleEvent);
}
-----------------------------
For my first implentation it was removed with the other dynamic controls with
this piece of code:
-----------------------------
for (i = initID; i < lastID; i++)
{
FrmHideObject(frmPtr,FrmGetObjectIndex(frmPtr, i));
FrmRemoveObject(&frmPtr,FrmGetObjectIndex(frmPtr, i));
}
------------------------------
I hope someone can help me.
Thanks for your time
