Cheers Tomasz, it was late last night when I encountered the problem and didn;t really have the time or the inclination to look further into it just then. THanks for clarifying my thoughts.

Multi CD-ROM App Problem

I have created a statically linked VS6 application that runs on a CD-ROM that will search and display encrypted data from that CD. It has to be a self-contained app with no dependencies ie run anywhere from any CD, this is working fine in a single cd state.
But the client wants multi-cd capability for future growth and when searching from the 1st CD everything again is fine, but when searching for data on the second CD, W2K throws up a dlg with this msg 'The wrong volume is in the drive. Please insert volume [Name of CD] into drive R:.'. After clicking any button I get this message 'The instruction at "0x00439558" referenced memory at "0x00439558". The required data was not placed into memory because of an I/O error status of "0xc0000012"'.
On Win95 I just get the blue screen (cannot read CD) only!

Any ideas on how to resolve this (I have attached remotely to a debug version and stepped through the code, still no wiser)??

When you say "multi-cd" here, I assume you are talking about multiple CD's and only one CD-ROM drive. Your problem seems to indicate this.

First you have to understand how loading and running programs is handled on NT. Then you apply the linker switch
/SWAPRUN:CD

Now your binary image (the program) is available even after you remove the mentioned CD.

If you also want to "help" the user by ejecting the wrong CD and ask for the correct volume, you can have a look at Q165721.

Non-Wizard CEdit Control

Hello,

I have created (in code, not the wizard) an array of CEdit boxes. I would like to be notified when the user has clicked in one of these boxes (and which box they clicked in). How would I get MFC to send me a message?

thanks!

Thanks for the reply...

So in my code, the "IDC_EDIT1" would be the 2200 (the control's nID)?

m_CEAvailable[i].Create(EditStyle | WS_TABSTOP, CERect, this, 2200+i);

Yes! but I would advise you to define IDC_EDIT1 (or whatever the name you like) and use it instead, cleaner!

CListCtrl: multi line report items, differing fonts

Hello,

I would like for my report-mode list control to do the following:

* Have text-wrapping on one line so that it's taller than a regular one-line item.

* Change the font (not just color) of each item and further, each sub-item.

Any suggestions or pointers to where to search? I've searched the MSDN somewhat and haven't found anything obvious.

Thanks!

Look in the MSDN Library for "custom draw" in the sections on the Common Controls. In the October 2001 edition, it's under Platform SDK Documentation \ User Interface Services \ Windows Common Controls \ Custom Draw Controls.

ICopyHook and files...

I have been playing around with ICopyHook, and have made a Shell Extension which implement ICopyHook, and it works perfect Smile | :)

The only problem is that ICopyHook only works with printers and folders. Is there any way to make something similar for files...

My problem is:

I´m trying to replace my file name from the CString wich value is "C:\esContaX\Archivos\TblPols.dbf" to finish with something like this: "C:\esContaX\Archivos\" using the following code: m_strAppPath.TrimRight('\'); , but I get the following errors:

--------------------Configuration: esContaX - Win32 Debug--------------------
Compiling...
esContaX.cpp
C:\esContaX\esContaX.cpp(230) : error C2001: newline in constant

Error executing cl.exe.

esContaX.exe - 2 error(s), 2 warning(s)

Can somebody help me showing me how can I acomplish this.

"\" is an escape character in C-strings. Like "\n" for newline. Just double up the "\" to get a "\".

"C:\\esContaX\\Archivos\\TblPols.dbf"

Ok this is the complete code
CString strSection = "Files";
CString strStringItem = "DataFiles";
m_strAppPath= theApp.GetProfileString(strSection, strStringItem);
// the value of m_strAppPath Now is = C:\esContaX\Archivos\TblPols.dbf
TRACE(m_strAppPath.GetBuffer(m_strAppPath.GetLength()));
//so trace shows C:\esContaX\Archivos\TblPols.dbf
m_strAppPath.TrimRight('\\');
TRACE(m_strAppPath.GetBuffer(m_strAppPath.GetLength()));
//Now trace shows the same value C:\esContaX\Archivos\TblPols.dbf
return TRUE;

TrimRight would trim only from Right and the first character found is 'f', so it cannot remove any '\' character. but if your path was: "C:\esContaX\Archivos\TblPols.dbf\", it would remove it!
Hope that helps!

an XOR problem!!!

ns11-Sep-02 9:39

My release version is running fine with this:

 xDontCare = "dontcare";

for (char* pc = xDontCare ; *pc ; pc++)

*pc ^= 0x30;

my debug version is crashing at the xor line. Why and how can I get past it? I rebuilt the project totally in debug version as well as release and its the xor....
help!

Don't try to modify read only memory. This is an undefined operation.

Well it is a bit of an assumption on my part, but if xDontcare is just a char *, then the

xDontcare ="xxxxx";

sets xDontcare to point to a readonly string.

#define dontCare "dontcare";
char szDontCare [64];
strcpy (szDontCare, dontCare);
for (char* pc = szDontCare; (*pc != '\0'); pc++) {
    *pc ^= 0x30;
}

Please don't write code like this:

while (*pc) {
  ...
}

It makes me weep. Cry | :((

Do this instead:

while (*pc != '\0') {
  ...
}

Why? Because it's easier to maintain. And maintenance costs about 4x development.

Okay I guess. Stuffs coming along so I cant complain. Lotsa little and big challenges every day. Missed you around -
Getting a new pc at work next month - hurray. I think I can spend upto 2500. Should be able to get a cool one. No XP allowed here though - so it will have to be (rolled back? ) to win2k. Oh well.
