RichEdit Streamin SF_TEXT not appearing
-
i'LL POST THREE pieces 1) the oninitdialog of the parent Cdialog 2) the Steamin 3) resource file Tell me if you want to see more thanks you
BOOL CStorge::OnInitDialog()
{
int numolines;storagepointer = new CRichEditCtrl; CDialog::OnInitDialog(); CHARFORMAT cf2 = { 0 }; STREAMIN((WPARAM)storage\_ptr, (LPARAM)storagelen); storagepointer->SetSel(0, -1); cf2.cbSize = sizeof(cf2); cf2.dwMask = CFM\_FACE | CFM\_PROTECTED; cf2.dwEffects = CFE\_PROTECTED; memcpy(&cf2.szFaceName\[0\], "Courier New",12); storagepointer->SetSelectionCharFormat(cf2); storagepointer->SetSel(0, 0); storagepointer->ShowWindow(SW\_SHOW); ShowWindow(SW\_SHOW); return TRUE;}
call to setup STREAMIN
LRESULT CStorge::STREAMIN(WPARAM mywparam, LPARAM mylparam)
{
char *sendptr;
sendptr = (char*)mywparam + 4;
streaminparm parms;
parms.storpointer = (char *)sendptr;
parms.storlen = (int)mylparam;EDITSTREAM STORAGESTREAM; STORAGESTREAM.pfnCallback = storagestreamin; STORAGESTREAM.dwCookie = mywparam; STORAGESTREAM.dwCookie = (DWORD\_PTR) &parms;long numstream = storagepointer->StreamIn(SF_TEXT,STORAGESTREAM);
return TRUE;}
the Streamin function
DWORD storagestreamin(DWORD_PTR dwCookie,
LPBYTE pbBuff,
LONG cb,
LONG* pcb){
static BOOL flag = 0; if (flag == 0) flag = 1; else { \*pcb = 0; flag = 0; return 0; } int i; streaminparm\* inparms = (streaminparm \*)dwCookie; void\* holdptr = inparms->storpointer; char\* holdptr1 = (char\*)pbBuff; int totalen = inparms->storlen; memcpy((char \*)pbBuff, "This is a test\\r\\n",16); \*pcb = 16; return 0; for (i = 0; i < totalen; i += storageline) { memcpy(holdptr1, holdptr, storageline); holdptr = (char\*)holdptr + storageline; holdptr1 = (char\*)holdptr1 + storageline; \*holdptr1 = '\\r'; holdptr1 = (char\*)holdptr1 + 1; \*holdptr1 = '\\n'; \*pcb += 74; } return 0;}
the Dataexchange member to create the rich edit HWND
void CStorge::DoDataExchange(CDataExchange* pDX)
{
CDialogEx::DoDataExchange(pDX);DDX\_Text(pDX, IDC\_ASID, asidstr); DDX\_Text(pDX, IDC\_SP, spstr); DDX\_Text(pDX, IDC\_TCB, tcbstr); DDX\_Text(pDX, IDC\_FP, fpstr); DDX\_Control(pDX, IDC\_EDIT2, (CWnd&) \*storagepointer);}
The resource indentfier of the cdialog with richedit

What is storage_ptr? Its type and value?

you think thats the problem I should make it a CRicheditrl * BTW I did Call AfxRichEditInit and I did observer that storage__ptr had a Hwnd after the DoDataExange
void* storage_ptr;

You mean you pass an uninitialized pointer into your STREAMIN method? BTW, did you debug your code (and, particularly, this STREAMIN method)?

The Ponter I pass to the streamin is 1) the data ptr and 2) the length of it I did debug it and it passed the value back that I wanted in pBuff and *pcb storage_ptr should be of type CrRicheditCtrl * instead of void * but it does a value and After the Call Cdialog::OnInitDialog it Called my DoDataExchage and had a valid HWND In in fact if you look at that small test when I pass "this is a test\r\n" back to pBuff and *pcb = 16 that doesn't display When I type any chanarcter in the rich edit for example a D this is a test follow it for example looks like this DThis is a test thanks

I could not test your "code" because there is a lot of problems with: undeclared identifier undeclared identifier cannot convert from 'DWORD (__cdecl *)(DWORD_PTR,LPBYTE,LONG,LONG *)' to 'EDITSTREAMCALLBACK' ... and so on. Could you post a code (sample project) that would reproduce your problem?

is there anywhere I could zip it if not the total project is 6 .cpp files with 6 headers and resource file thanks you are really nice
Sorry! I don't know. But if you won't find a way to do that then you could repost your question in [Visual C++ Programming](https://forums.codeguru.com/forumdisplay.php?7-Visual-C-Programming) Or just email it to me: at

Ill take the latter thanks but this mini project is a tcp/ip application that gets data into the RichEdit from a z z/os machine let me see if I can somehow segregate it The rich edit portion that is causing the problems and then get a clean build and i'll send it over thanks you are very nice

You have to simplify your project code until it will reproduce the problem. Just make a very simple project with your RichEdit without any TCP/IP and other IPCs. Test it. If you won't find the reason of the trouble while debugging this test project then post it to me or/and to the community.

No idea until we will see your actual code.
Victor commented out IDC_EDIT1 and the stream out worked you are very nice guy for your offer

Yes, it is what I meant in my previous post. :)
