I try to implement new methods to the RichEdit Class by just me.
I've succeeded for some but don't succeed with EM_GETTABLEPARMS and EM_INSERTTABLE (used to get a table's parameters or Insert a new table)
Both messages returns -2147024809 which i believe is E_INVALIDARG.
If someone could try to explain why this returns an error that would be fantastic !
(I've asked just me but I guess this is quite a standard issue so anyone could help)
I've put every documentation in the code below.
I've tried to do everything according to documentation and even a post of a guy on MSDN said was working.
I've tried some variations but couldn't make it work, always the same ErrorLevel
You can try the following code with the sample contained in the Class from just me
https://github.com/AHK-just-me/Class_Ri ... master.zip
Code: Select all
RN_GetorSetTableParams:
EM_GETTABLEPARMS := 0x400 + 265
EM_INSERTTABLE := 0x400 + 232
; EM_SETTABLEPARMS := 0x400 + 307
;*****************************
; EM_GETTABLEPARMS := 0x509
; Returns S_OK if successful

; A pointer to a TABLEROWPARMS structure.
; A pointer to a TABLECELLPARMS structure.
; Retrieves the table parameters for a table row and the cell parameters for the specified number of cells.
;*****************************
; "E_INVALIDARG" SAYS:
; The wParam or lParam is NULL or points to an invalid structure. The cbRow member of the TABLEROWPARMS structure must equal sizeof(TABLEROWPARMS) or sizeof(TABLEROWPARMS) – 2*sizeof(long). The latter value is the size of the RichEdit 4.1 TABLEROWPARMS structure. The cbCell member of the TABLEROWPARMS structure must equal sizeof(TABLECELLPARMS).
