Why not use RegQueryValueEx(..., REG_BINARY, ...)?

And if I want to display this in a static control, what do I do?

To display anything in a static control, use SetWindowText().

Hi, I am looking for a very simple way to implement a function with the mouse similar to kbhit() in C++ through windows xp... I just want to have the program be able to read a mouse click and possibly set an integer value depending on if the click was a right or left click... If someone could please help with this I would really appreciate it!

On what would the mouse be clicked?
Here are some things to search for:
WM_LBUTTONDOWN
WM_RBUTTONDOWN

I need to modify an industrial application to display chinese characters as well as english text. I have followed many suggestions, tips, advice, etc. in many directions and have wound up right where I began. Is there an easy way to gain this functionality without having to reinvent the wheel? I have enabled the proper fonts and language support packages. I can type chinese characters in Notepad using ALT + the character code, however, this doesn't work in the Developer Studio.
Any suggestions, tips, ideas....???
Thanks so much

Edit the PreCreateWindow function and add:
cs.style &= ~WS_THICKFRAME;
That should take care of it for you.
Hope that helps.

Hi, is there sample code to kill or shutdown another mfc dialog application (.exe) from an mfc application ? THANKS !

Why not just post a WM_CLOSE message to it? If that does not work, try TerminateProcess().

All i want to do is get all of the text together from an array of CString objects and put it into a single char* pointing to a string. I'm doing memory allocation and I can't find away to delete the original temp data. It works, but..."I'm stomping on other memory!" 
This should be the easiest thing ever. But i'm worried about a memory leak here. Whenever I try to delete allText before creating a NEW allText allocation, it dies. Any ideas how to fix these memory leaks?
char* CFindInWindowDlg::GetTextLinesBuffer()
{
char* allText = NULL;
char* source = NULL;
int sizeAllText = 0;
if (numLines > 0)
{
// **** 'lines' is my array of CString objects!!!
int sizeAllText = strlen(lines[0].GetBuffer(0));
source = new char[sizeAllText];
strcpy(source, lines[0].GetBuffer(0));
for (int a = 1; a < numLines; a++)
{
// **** 'lines' is my array of CString objects!!!
sizeAllText = MergeLines(&allText, sizeAllText, &source, lines[a].GetBuffer(0));
source = allText;
}
}
return allText;
}
int CFindInWindowDlg::MergeLines(char** allText, int sizeSource, char** source, char* aLine)
{
int newSize;
if ((sizeSource == 0) && (*source == NULL))
{
*allText = new char[strlen(aLine)];
newSize = strlen(aLine);
strcpy(*allText, aLine);
return newSize;
}
newSize = sizeSource + strlen(aLine);
*allText = new char[newSize];
strcpy(*allText, *source);
strcat(*allText, aLine);
return newSize;
}

C-style strings are null-terminated, meaning there is a 0 byte to mark the end of the string. strlen() does not include that byte in the length, so you end up not allocating space for that byte.
source = new char[sizeAllText+1];

Actually the code works fine. Everything is allocated the way i want it to. The only problem is deleting. I can't seem to do that.

Why are you wanting to do this? The whole reason for using CString is so that you would not need to mess with char variables and memory allocation/cleanup.

strcpy(source, lines[0].GetBuffer(0));

The calls to GetBuffer() are not necessary. Remove them.

Change the last parameter to const char * instead.

When I attach the CStrings together (newString = string[0] + string[1] + string[2] ..), the result does not correctly append the strings. My strings contain '\n' and '\r' characters and it seems that when I use the newString += string, only the first result is copied.
Here is an example:
string1 = "this is a string \r\n";
string2 = "this is an appended string \r\n";
string1 += string2;
string1 still equals "this is a string \r\n" and doesn't append string2!!
I need those '\r' and '\n' characters. By putting them all into a char string, it fixes this problem.

This works:
char* CFindInWindowDlg::GetTextLinesBuffer()
{
CString allText = "";
for (int a = 0; a < numLines; a++)
{
allText += lines[a].GetBuffer(0);
lines[a].ReleaseBuffer();
}
return allText.GetBuffer(0);
}
Any idea why I need to use GetBuffer instead of string1 += string2?

That may seem to work, but it actually doesn't. You can't return a pointer to the internal buffer in allText, since that variable will be destroyed as soon as the function terminates.
Check the code I suggested in a previous post (the function receives a CString reference from the caller and stores the result in it).

You don't need to use GetBuffer; that's not the problem.

A classic case of "MFC must be broken because my code works just fine."
Wrong.

I'm going to patent thought. I have yet to see any prior art.

Try this:
CString strAll = lines[0] + lines[1] ...

I tried that but it didn't work.
Here is an example of what happens:
string1 = "this is a string \r\n";
string2 = "this is an appended string \r\n";
string1 += string2;
string1 still equals "this is a string \r\n" and doesn't append string2!!

In the debugger.. There is no change to the original string:
originalString = "the original string \r\n";
originalString += "a new string \r\n";
------
originalString still equals "the original string \r\n";
Do you get a different result?
