Pass them with the lpFile or lpParameters parameters of the ShellExecute() function:
ShellExecute(NULL, _T("open"), _T("myfile.exe \"file 1\" \"file 2\""), NULL, NULL, SW_SHOWNORMAL);
ShellExecute(NULL, _T("open"), _T("myfile.exe"), _T("\"file 1\" \"file 2\""), NULL, SW_SHOWNORMAL);
Note that i have quoted the file name in the parameters using escaped quote characters. This is necessary when the file names and the executable contain spaces.

I have 2 tabs in my program on first tab i have 10 MFCEDitBrowse control
and on second tab I have calculate button when ever
i clicked on calculate button it should called .exe file and input for .exe file is
selected files in mfceditbrowse control on (tab1).
selected files are not fixed it is between 1 to 10.
Please help me out I dont understand how i can give filename(with path) from mfceditbrowse
(dlg1) to .exe file (dlg2)

I don't understand where the problem is. Just create a string with the file names from your browse controls and pass this string as parameters to ShellExecute(). When creating the string, separate the file names by spaces and quote them using double quotes when they contain spaces:
void CMyClass::AppendFileName(CString& str, LPCTSTR lpszFileName) const
{
bool bMustQuote = _tcschr(lpszFileName, _T(' ')) != NULL;
if (!str.IsEmpty())
str += _T(' ');
if (bMustQuote)
str += _T('"');
str += lpszFileName;
if (bMustQuote)
str += _T('"');
}
void CMyClass::ShellExecute()
{
CString strParameters;
CString strFileName;
strFileName = GetNameFromBrowseControl1();
AppendFileName(strParameters, strFileName.GetString());
ShellExecute(NULL, _T("open"), _T("myfile.exe"), strParameters.GetString(), NULL, SW_SHOWNORMAL);
}

Separate your problem into two smaller problems. First get the filenames from the various controls. Once you have successfully done that, then worry about passing those names to the EXE.

hi,
i need to update .properties file example
log4j.logger.PXPBroker=TRACE, C, fileappender
log4j.additivity.PXPBroker=false
log4j.appender.C=org.apache.log4j.ConsoleAppender
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.fileappender=org.apache.log4j.RollingFileAppender
log4j.appender.fileappender.File=C:/pxpserver/logs/pbesb.log
i want to update these values in c++ please help me.

Use one of the fstream[^] classes to read the file, change the values that you wish to update, and write the changed values with another fstream object.

Apparently MFC has no classes to encapsulate static text or group boxes.
What is the preferred method for resizing them as the user resizes the window?
The difficult we do right away...
...the impossible takes slightly longer.

Your question could do with a bit more detail; what exactly are you trying to do? You can use the CStatic Class[^] for static text, and that is resizable (as is any window).
Use the best guess

Thanks.
I assumed there was no MFC class because the "Add Variable" wizard did not present me with one.
I've created a small class that automatically resizes and repositions controls when a window is resized, and I inherited from classes liked CComboBox, CListBox but I didn't see the CStatic class.
Thanks again.

This is not a programming "how to", just looking for short explanation/ verification of usage of "moniker".
My basic understanding is that it's function is similar to DOS path, allowing access to an object.
Now it this particular sequence I do not get the enumeration, followed by getting the first moniker and bind it to , I guess filter.
This is part of my code to get data from USB camera and I am still learning how to put all this COM and DirectShow stuff together.
This is what I understand so far – the enumeration identify the “object class” in my case USB cameras and than I can select which one using the Next in loop ( this snippet gets only the first one) and than let the filter “connect / bind “ to the selected camera.
This is still plain COM code , no DirectShow.
Am I right so far?
Thanks for reading.

COM has been evolving since before Windows 3, so there's stuff lingers on because of backward compatibility that won't break existing code.

Hey coders,
I came up with a little puzzle/challenge for C++, so for those interested, my challenge to you is this:
Using any C++ constructs, other than any of the casting constructs*, reimplement the following code:
int i = someIntValue();
int *pint = reinterpret_cast<int*>(i)
Or in words, find a way to reinterpret_cast an integer into a pointer without casting (implicitly, or explicitly!). You may assume that sizeof(int)==sizeof(int*).
I hope to be surprised by answers I hadn't thought of
* with casting constructs, I mean any form of implicit casts (e.g. int to long int), C-style casts (e.g. (int*)i) and C++-style casts (e.g. reinterpet_cast<int*>(i)); and also any functions/macro's/API calls (such as STL implementations) which rely internally on casts.
Best Regards,
Richard

Hmmm  Didn't realise that.
I felt it was more in place in a C++ specific message board than in a lounge, as I do find such challenges to be stimulating myself.

I deem this is technically appropriate (by the definitions of the rules), it is C++/C code.
Where in the rules up at the very top posted by Admin Chris Maunder, does it directly say that is for serious questions.
Keep in mind a quiz is a question, you are giving an answer.

You could do something like:-
int i = 42;
int* pint = 0;
int** ppint = 0;
ppint += &i;
pint = *ppint;
If I'm not mistaken pint is now an int pointer to address 42 and no casting as such has taken place.

Doesn't work - you only can add integral types (size_t and anything that implicitely converts to size_t) to a pointer.
Also, as Harold Aptroot pointed out in response to my variant, even if it would work as intended, pint would point to 42*sizeof(int), not 42.

I haven't tried it as it's, as you point out, not of practical use but &i is certainly integral. Another step may be needed to get around restrictions on adding pointers to pointers but the principle is the same. The multiplication by sizeof(int) is not an really issue as this can be overcome without any casting.
The addition was a syntactic nicety to explain what I was doing anyway and is not strictly necessary. How about:-
int i = 42;
int** ppint = &i;
int* pint = *ppint;
which is shorter and doesn't do pointer arithmetic.

Dear Matthew,
Thanks for submitting your solution. Unfortunately, ppint is of type int**, whereas &i returns an int*, so this will not work without casting int* to int**.
