I'm not an expert, but I see a couple of things that seem incorrect to me.
I believe you're writing into unallocated memory. First, for you var, you can allocate memory either via MemHandleNew or initialize your var as: char str[100]; //where 100 would be replaced with the max_length you want Your initialization was creating a char array of fixed length and you were overwriting with StrCat. Also, StrCat's args are (destination, src) and it returns destination also. So in your first call to it you were telling the OS to add "." to getTim() and place it in getTim() which isn't a variable. I think what you want is: char str[100]; StrCat(str,getTim()); StrCat(str, "."); StrCat(str,getMin()); Hope this helps.

I have 2 functions: getTim and getMin, they return a char*. I want to concatenate these to strings with a "." i the middle. But when I do this I get the error message: CTR(unknown version)just wrote to memory location 0x00030E83, which is in the storage heap. In order to protect the integrity of the user's data, such direct access is not allowed. Instead, applications should use special Palm OS functions for this purpose. It seems that StrCat is not available, does any of you know what I shold use instead?? this is my code: char* str= " "; str= StrCat(getTim(), "."); str= StrCat(str,getMin()); //write to the field: UInt16 Index = FrmGetObjectIndex(form, fldMon); FieldType *ptr = (FieldType *) FrmGetObjectPtr(form, Index); FldSetTextPtr(ptr, str); FldDrawField(ptr); _________________________________________________________________ Hämta MSN Explorer kostnadsfritt på http://explorer.msn.se -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
