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

Re: RichEdit Streamin SF_TEXT not appearing CODE POSTED !!!!!

31-Jan-22 3:31

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

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?

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

Re: RichEdit Streamin SF_TEXT not appearing CODE POSTED !!!!!

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.

For the class parameter the documentation says a redefined name (not sure what that means) the reason I am asking I am using a control for which I have a specific WNDCLASS which I registered however the CDialog::Create fails with that control statement in the resource definition

Thanks

We need to see the code and a bit more detail. If the control is not known at build time then the resource compiler may well have a problem.

As Richard said, we need more information:
- what is "the class parameter"?
- what is "the documentation" you are referring to?
- what is "the CDialog::Create"?
- also: in what way does it "fail"? Is there a compiler, linker or run-time error, and what does it say? Or does you program not behave in the expected way - if so, how, and what did you expect?

You are apparently referring to very specific things, but we have no idea what you're seeing or reading. (or whether that is relevant information to start with)

GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

I am not sure as I have never tried that. The documentation at CONTROL control - Win32 apps | Microsoft Docs[^] states (although it is slightly ambiguous) that it must be one of the predefined classes. If your code is failing when you try it with a locally defined class then you need to use the debugger to find out why.

ForNow26-Jan-22 4:52

26-Jan-22 4:52

I think the documentation means you have to Register the Class before calling CDialog::Create as I remember I forgot to call AfxInitRichEdit before doing a CDialog::Create and it failed I think CDialog::Create Checks Uid template dialog resource and sees if the classes are registered

Thanks you

I assumed you were doing that anyway, since Windows cannot create an object of a class that it does not know about.
