RichEdit Streamin SF_TEXT not appearing
-
Hi I have done this many times streamin text, this time however the text just doesn't appear I do a SW_SHOW on both the rich edit and the dialog So I decided just to do a simple test copy "this is a test\r\n": info the pBuff *pcb = 16 for the next call I have *pcb = 0 to tell rich edit no more The Dialog box and rich edit appear with no test however When I press any character on my keyboard e.g type D The text This is a text magically appears in front of D Any ideas are appreciated
No idea until we will see your actual code.

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

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.
