I did what you said PJ and it eliminated 3 of the errors, now I only have 2 errors left...see below. I'm not sure what a dialog is. I thought specifying the header was enough, no?
Thanks, Dave

Oh boy
A dialog is a form based window that is used to get input from a user. The colour picker, font picker, and file open/save dialogs that you encounter frequently are examples of dialogs.
Check out these articles for a good beginners intro to using dialogs

I'm not sure what you mean by "dialog resource." I know what a dialog box is, I should have been more specific.
I found this project in the archives. It builds a window in a CONSOLE program. You referred me to the MFC tutorials, that's a different ball game. I'm just trying to study the differences between the type of programs. I still can't get the above program going. It wants something in the header file. Anyone?
Thanks much, Dave

VC++ needs the dialog resource file which it should have got from resource.h.
If you used the wizard to create a simple application and then pasted the code, then it may have created the resource.h for you, but it is empty, and you should create a dialog with the id that is missing...
Sorry that I can't be more specific, but it is ages since I last used resources.

I found this project in the codeproject archives but I'm getting the error messages at the bottom. I was hoping someone might give me a hand getting this going. Am I missing a header or something? Thanks, Dave

I an use the function Drawtextw output some words,
Is this function in the windows98 support?
if it not support, Should I how do?

I'd suggest you start with msdn.microsoft.com. The full answer to your question is easily found there.

Yes, using the Microsoft Layer for Unicode. See MSDN for more information on using this.

I am in a Dialog use pView->ReplaceSel(szData1,true) insert a Unicode char to view，I can't insert it rightly, the some word sign shows the disorderly code after inserting.
What my engineering use is not the method of unicode.
how I can insert these unicode characters rightly?
|
|
|
|

Is it because your OS doesn't support the UNICODE?
I know only NT , 2000 and XP automatially support UNICODE.
Win98 and below I think it is not automatically available.

My os is widows 2000 server,I can output the character rightly use the following code in a dialog,
i is a interger between 0 and 65536
wchar_t cTemp=i;
::DrawTextW(HDC(*pDC), &cTemp, 1, rcText, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
but I cant't output them in a view rightly use this code pView->ReplaceSel(szData1,true);

Here are portions of my code. The rest of the program is working fine, but at strategic spots I'd like to see what the state of certain values are (shown together in one convenient way).
Where the structure is being initialized, data are already in the variables from which it gets initialized.
======================================
struct IData
{
char* str;
char* pO;
char* pGH;
char* pIntrm;
int wrdlen;
int lvlcnt;
int ltrcnt;
} idata, *pIData;
// other program code
ostream& operator<< (ostream& outp, const IData IDat)
{
char Bufr[40] = " ";
char* Ptr_fmt[] = { pIData->str, pIData->pO, pIData->pGH, pIData->pIntrm };
int i, Dec_fm[] = { pIData->wrdlen, pIData->lvlcnt, pIData->ltrcnt };
i = sprintf(Bufr, "\tstr: 0x%x\n", *Ptr_fmt);
i += sprintf(Bufr+i, "\tOutput: 0x%x\n", *(Ptr_fmt+1));
i += sprintf(Bufr+i, "\tGrp Hold: 0x%x\n", *(Ptr_fmt+2));
i += sprintf(Bufr+i, "\tInterim: 0x%x\n", *(Ptr_fmt+3));
i += sprintf(Bufr+i, "\tWord len: %d\n", *Dec_fm);
i += sprintf(Bufr+i, "\tLevel cnt: %d\n", *(Dec_fm+1));
i += sprintf(Bufr+i, "\tLetter cnt: %d\n", *(Dec_fm+2));
outp<< IDat;
return outp;
}
// other program code
for(int lvl_cnt=0; lvl_cnt<<wordlen; ++lvl_cnt)
{
ltr_cnt = ++lvl_cnt;
pIData->str = str;
pIData->pO = pOut;
pIData->pGH = pGH;
pIData->pIntrm = pIntrm_str;
pIData->wrdlen = wordlen;
pIData->lvlcnt = lvl_cnt;
pIData->ltrcnt = ltr_cnt;
cout<< "\n *** " << idata <<endl;
lvl_cnt--;
}
======================================
In the "for" statement, I had to use two "<" signs, because without it the CodeProject editor would not show the rest of the statement.
After a while, things begin to get blurred. So, I thank you for whatever you may see as the reason why nothing gets shown.

Your operator<< is not sound. First, you're overrunning Bufr, you'll need much more than 40 characters for all that output. Second, you're not doing anything with Bufr. Third, it has a parameter IDat that you don't use; instead you refer to pIData.

Thank you for your insightful reply. However, while I'm happy to report that with the changes made (directly due to the points you made), data has now begun displaying. That's the good news!
The bad news is that they're garbage!
Here is the new code:
ostream& operator<< (ostream& output, const IData& idata)
{
char Bufr[200] = " ";
char* Ptr_fm[] = { idata.str, idata.pO, idata.pGH, idata.pIntrm };
int i, Dec_fm[] = { idata.wrdlen, idata.lvlcnt, idata.ltrcnt };
i = sprintf(Bufr, "\tstr: 0x%x\n", *Ptr_fm);
i += sprintf(Bufr+i, "\tOutput: 0x%x\n", *(Ptr_fm+1));
i += sprintf(Bufr+i, "\tGrp Hold: 0x%x\n", *(Ptr_fm+2));
i += sprintf(Bufr+i, "\tInterim: 0x%x\n", *(Ptr_fm+3));
i += sprintf(Bufr+i, "\tWord len: %d\n", *(Dec_fm);
i += sprintf(Bufr+i, "\tLevel cnt: %d\n", *(Dec_fm+1));
i += sprintf(Bufr+i, "\tLetter cnt: %d\n", *(Dec_fm+2));
printf(" *******\n %s\n", Bufr);
output<< idata;
return output;
}
=========================================
Perhaps, helpful to mention is that just before the "for" loop is entered, the structure is instantiated to:
IData idata;
and upon entering the loop, the structure is initialized with data that are already present in the variables to which it is being initialized.
Right after those initializations take place, this is the statement that follows:
cout<< "\n\n ^^^ " << idata <

Hi William,
I may be wrong, but I think your call to output<< idata; would cause an infinite loop. (you are calling your operator<< from within your operator<< )
perhaps it should be output << Bufr;?

Thanks! Your suggestion worked (no more wild antics by "printf"), but garbage still got printed out.
Holy moly! I KNOW those variables used to initialized the structure, ARE themselves, already initialized. Might returning Bufr instead of idata have anything to do with garbage being displayed? (I don't know. It's been a long day for me.)
In case anybody start wondering, the answer is, "Yes," I moved Bufr outside the overloaded function and made it a global variable (just for this time), otherwise it was going to get destroyed whenever the function exited.
Thanks again!

Use the debugger. View the memory that the pointers point at. Double-check that you've got the right addresses. Step into sprintf(). Etc. That's what the debugger's there for

I have to ask: why the heck are you messing around with sprintf and a buffer inside an operator << function??
Try the following:
ostream& operator<<( ostream& output, const IData& idata )
{
output << "\tstr: 0x" << (void*)idata.str <<
"\n\tOutput: 0x" << (void*)idata.p0 <<
"\n\tGrp Hold: 0x" << (void*)idata.pGH <<
"\n\tInterim: 0x" << (void*)idata.pIntrm <<
"\n\tWord len: " << idata.wrdlen <<
"\n\tLevel cnt: " << idata.lvlcnt <<
"\n\tLetter cnt: " << idata.ltrcnt << "\n";
return output;
}

Thanks for your reply!
What started out as a quick and dirty way to see data, turned out to be not so quick, and was getting rather dirty.
Your point is well taken, and thanks for bringing back some reality to the situation.
