RichEdit Streamin SF_TEXT not appearing

[ForNow]

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?

[ForNow]

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)?

[ForNow]

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

[Victor Nijegorodov]

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?

[ForNow]

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

[Victor Nijegorodov]

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

[ForNow]

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

[Victor Nijegorodov]

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.

[ForNow]

Will do thank you

Victor commented out IDC_EDIT1 and the stream out worked you are very nice guy for your offer

[Victor Nijegorodov]

Does it mean that your text was under the IDC_EDIT1 control? Or what???

[ForNow]

No just commented out that control maybe it overlaid IDC_EDIT Thank you

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