I'm pretty sure MS has an SDK for dealing with .BSC databases, but I've tried a few searches and can't find it now. Check around the MS Visual Studio site, maybe you'll have better luck than me.

Thanks this was very useful. Unfortunately, the SDK does not allow writing new information to the .bsc file, just reading a searching it (unless I'm missing something obvious). They supply a .dll that does all the reading, so the file format is still a mystery. What I need to do is create .bsc files.

Thanks, RZ

1. In the view GetParentFrame()->ShowWindow(SW_SHOWMAXIMIZED);

2. I'm guessing in the view do the abvoe with SW_SHOW, or use the same technique to get a HWND to call SetWindowPos on.

If by 'view' you mean MDI child frame, this is the way to go:

1) MDIMaximize

2) MDIActivate

Both methods are available from CMDIChildWnd (this is the base class for CChildFrame) and CMDIFrameWnd (the base for CMainFrame).

overloaded operator +

23-Oct-01 15:30

I have this code but need to be able to concatinate the two strings passed in using the overloaded + operator function. Help.
#include "myString.h"
#include <iostream.h>
#include <string.h>

myString::myString() // default constructor
{
length = 0;
stringData = new char[1];
}

myString::myString(char *A) //conversion constructor
{
length = strlen(A);
stringData = new char[length];
for (int I=0;I<length;i++)
{
="" stringdata[i]="A[I];
" };
}

void="" mystring::show()="" shows="" the="" converted="" string
{=""

What about this.

myString operator+(myString A,myString B)
{
   int nLength = strlen(A);
   nLength += strlen(B);

   char* pStr = new char[nLength+1];

   for(int nCnt = 0; nCnt++; nCnt < (strlen(A)-1))
      pStr[nCnt] = A[nCnt];

   for(nCnt = 0; nCnt++; nCnt < (strlen(B)-1))
      pStr[strlen(A)+nCnt] = B[nCnt];

   pStr[nLength] = 0; // Null terminate

   myString str(pStr);

   return (str);
}

Think it should work.

Or strcat ? I suspect he's doing a homework assignment ( which is fair enough, he's had a go and posted code to ask for help, but I can't think of any other reason to write another string class. Having said that, I did it for the sake of the exercise, although I obviously use basic_string rather than my own, that was not the point. ).

He may be doing what he's doing because...

a) the existing code that has to be amended but cannot be changed beyond the new code being added

b) an insane project lead refuses to think outside the box and insist that the guy use his (the project lead) classes

c) he's doing a homework assignment which requires him to write his own string class

d) he doesn't like the std::string class

Why can't you just answer the question posted instead of asking why he doesn't use this or that?

Thanks,

	LPNMCUSTOMDRAW pcd  = (LPNMCUSTOMDRAW)pNMHDR;
	
	if (CDDS_PREPAINT == pcd->dwDrawStage)
	{

		return;
	}
	
	*pResult = 0;


	if (TBCD_CHANNEL == pcd->dwItemSpec && 
		CDDS_ITEMPREPAINT == pcd->dwDrawStage)

		dc.Attach(pcd->hdc);
		CRect rc;

I can kind of get it to work. My control won't draw itself unless I set a breakpoint somewhere in the function and press F5 repeatedly. I am not sure if I have my message handler set up right. If anyone has a complete implementation that they could share with me so I can study it.

All help is much appreciated!

File Save As... and UNC File specifications

23-Oct-01 12:44

I have an MDI app that contains an open and modified document. The file specification of the document is in a UNC format (GetDocument()->GetPathName() returns \\Server\Share\MyDocument.txt). When I click on Save As, MFC calls GetSaveFileName() for me to display the CFileDialog so that I can enter a filename. When the dialog box is displayed I get four copies of the following message displayed in the debugger's output window: "First-chance exception in MyProgram.exe (RPCRT4.DLL): 0x000006BA: (no name)." If I look at the m_ofn.lpstrFile member variable that GetSaveFileName uses, the filespec is in UNC format. If I gludge things up, map a drive, and change m_ofn.lpstrFile to be a normal file spec (c:\temp\MyDocument.txt), I don't get these exceptions! In either case, the Save As appears to work just fine - the exceptions don't seem to bother things.

Does anyone with UNC experience know what is going on here? Is there something special I need to do when using UNC file specs - i.e. some flag I need to set?

Thanks,
Don Sanders

I don't have much UNC experience, but think that you can safely ignore these messages. KB article Q105675 has more info on 'first-chance exceptions'.

According to Big Bad Bill, Beep() does the right thing on NT (and perhaps 2000), but not on Win 9x/ME.
