Hi,
is there a way to monitor events and messages sent from/to for a particular application? If so, how? 
Thanks!

i highly recommend (hope i'm not going to be bashed) that you look at http://www.sysinternals.com[^]
They have many usefull simple apps, and very often with source code.
P.S.: I am in no way affiliated to sysinternals, i just use their apps that i find very usefull.

I certainly hope you wouldn't get bashed for recommending an excellent resource such as sysinternals.

I am able to get the Add-In displayed in the Add-In Manager Dialog Box but I can't get the icon to be displayed in a toolbar. Anybody know how to?

Should there be an icon? I recently installed XC# and there's no icon. Perhaps it depends on the Add-in?

Is this your own code or some random add-in you loaded on the net ?

I have stored in a database a rescaling factor "0.5/pow(2, 14)".
My question is as its stored as a string how do I use it?
I did try in my project:-
#define scaleFactor1 (data_details[index].scaling)<br />
float rescaledData = currentField * scaleFactor1;
But this does not work; get error:-
c:\Export_Lib\Export_LibDlg.cpp(353): error C2297: '*' : illegal, right operand has type 'char [30]'
Also the macro would be redefined as the statements are in a loop.
Also I did try:-
float scaleFactor1 = signal_details[index].scaling;
But the same error, what I expected.
Are they any tricks that can be aplied to this string to make it usable in the code.

Convert it to a floating-point number using atof().

Did think of that but it gives 0.5 for the string "0.5/pow(2, 14)".
The pow(2, 14) is present for the resolution required.
Any other suggestions?
Graham.

As it should, because the '/' character terminates the conversion.

The database stores the scaling factor as a string, due to its resolution. I have arranged the scaling factor to be in a format suitable for processing by C++ code. Hence the pow(2, 14), but apart from say arranging the output process to define something like the following:-
#define SCALING_1 0.5/pow(2,14)etc
The scaling factor is held in a array, but
#define SCALING_1 details[k].scaling // 0.5/pow(2,14)
does not work

Hello,
If your scaling factors are all in the same format, you should write a function that'll parse the string.
For exemple:
If the format would be < float ><opration>pow(< arg1 >< arg2 >) than you could write a function that will do the parsing for you.

I'm have a MFC project which includes a button. When pressed, i want the SaveFileDialog box to come up. I've been using the examples i've seen around online to get started but I still get errors. Here is the code I've been using:
void CProductVersionsDlg::OnButton2()
{
SaveFileDialog sdf = new SaveFileDialog();
sdf.AddExtension = true;
sdf.CheckPathExists = true;
sdf.InitialDirectory = @"C:\";
sdf.DefaultExt = "*.txt";
sdf.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
sdf.ShowDialog(this);
MessageBox.Show(sdf.FileName);
}
"Error:error C2065: 'SaveFileDialog' : undeclared identifier"
there are many more errors but this is the first one
I think I am missing a .h file to include.
What is the name of the file i need to include? I've been looking around online but i can't find any include files, or is it something else?
I'm running Microsoft Visual C++ 6.0 on a windows 2000 system.

well, SaveFileDialog is not an MFC class ...
maybe the example you looked at defined their own SaveFileDialog class to wrap the CFileDialog ( or GetSaveFileName API )

just call the function (SaveFileDialog is not a class).
<font style="color:blue;">void</font> CProductVersionsDlg::OnButton2() {
SaveFileDialog sdf = SaveFileDialog();
sdf.AddExtension = <font style="color:blue;">true</font>;
sdf.CheckPathExists = <font style="color:blue;">true</font>;
sdf.InitialDirectory = @<font style="color:gray;">"C:\"</font>;

sdf.Filter = <font style="color:gray;">"Text files (*.txt)|*.txt|All files (*.*)|*.*"</font>;
sdf.ShowDialog(<font style="color:blue;">this</font>);
MessageBox.Show(sdf.FileName);

Hi
I am writing a program which Creates Three entries into the windows registry but on some systems instead of creating the registry it locks the registry HKEY_LOCAL_MACHINE\SOFTWARE part and shows error "Access is denied" and after that it does not allow to create a entry into the registry, it seems that registry got corrupted but windows still works fine. I don't know. Is it the problem of Rights to write into the registrry or something else.This program works fine on my machine but does not works on some machines. Please help...
BOOL CGenUniqueKeyXDlg::SaveValueToRegistry(char *pcszValue)
{
DWORD dwLen = 0;
int nReturnVal;
HKEY m_hContextKey;
DWORD dwDisp;
nReturnVal = RegCreateKeyEx(HKEY_LOCAL_MACHINE , //Handle to a currently open key
REG_LOC_PATH, // Sub Key Name
0, //Reserved
NULL,
0,
KEY_WRITE,
NULL,
&m_hContextKey,
&dwDisp );
if(nReturnVal != ERROR_SUCCESS)
{
ShowRegError(nReturnVal);
return FALSE;
}
nReturnVal = RegSetValueEx(m_hContextKey, UNIQUE_KEY, 0, REG_SZ, (PBYTE)pcszValue, (_tcslen(pcszValue) + 1) * sizeof(char));
if(nReturnVal != ERROR_SUCCESS)
{
ShowRegError(nReturnVal);
return FALSE;
}
strcpy(pcszValue,m_SyncURL);//"http://Nopd/CiteCapture/MDCSync.aspx";
nReturnVal = RegSetValueEx(m_hContextKey, URL_KEY, 0, REG_SZ, (PBYTE)pcszValue, (_tcslen(pcszValue) + 1) * sizeof(char));
strcpy(pcszValue,m_Port);
nReturnVal = RegSetValueEx(m_hContextKey, COM_PORT, 0, REG_SZ, (PBYTE)pcszValue, (_tcslen(pcszValue) + 1) * sizeof(char));
RegCloseKey( m_hContextKey );
return TRUE;
}
Any input will be appreciated
Thanks

Are you sure you have 'write' permission on those particular machines? Much like you can with folders and shares, the registry can be tuned to allow/disallow certain users/groups.

If i don't have write permission on that machine how can i write my entries in the Registry. In my code i am passing the Write Registry Permission as a parameter. Actuall i have made a installable with installed shield which runs my program at last for creating some entries. But it is corrupting the registry.... What about code is that fine or seems some problem?????

One way to tell would be to use regedit.exe to try and write something to the same spot in the registry as the code is. Be sure and log in using the same credentials as the person running your code.

You're asking for write access to a key under HKLM. RegCreateKeyEx() is returning access denied, which means the user doesn't have write privileges to that key. Run your code as a restricted user (not admin) and you'll see the same error.

I have a file with a lot of text and I want to find some text and when I do that I need to insert some text at the same line as that text.
Exempel;
bla bla bla
hello
c++ mfc test
ok ok
And if a find hello I need to insert text after hello how do I do that?
Please help me..

Well, you could read the file in line-by-line and output each line to a temporary file. When you get to the line in question, output the additional text.
If, however, you can read the file in as one big blob, you can use one of the various 'find' functions (e.g., CString::Find()) to locate the text. Write everything up to that point to a temporary file. Insert the additional text. Write the remainder of the original file to the temporary file.
In either case, when done, close both files, delete the original file, and rename the temporary file.

What do you mean by "just?" Wouldn't one or both or my suggestions do what you require?
