Tires to follow the sample code in MSDN, too complicated. Any simplier code available?

If you want it simpler, you'll need a wrapper class. there are s everal here on CP.

Hi
I'm working on a project both on my home computer and work computer. I transfer the source and header files using a flash drive. I have two seperate project (.dsw) files, one at home and one at work. I just link the source files in the flash drive to the home or work project and then continue working. However, now that I'm starting to work with the GUI interface, I need to how to transfer the form Graphic back and forth between computers. I can move the source and header file, but not the graphic that you actually lay buttons and menus on. Does anyone know how to move this graphic back and forth?

You need to move the resource file, I forget what their file extension is.

I have an ActiveX control that I wrote that is a Simple Frame Control with an Embedded Property Sheet. The sheet has 2 pages with each page having a few controls on it. Here is its basic structure:
- Control Class
---- Property Sheet Class
-------- Page 1 Class
-------- Page 2 Class
This control works fine in the ActiveX Test Container as well as when I put it on a dialog by itself. However, if I put an OK button on the dialog with the control, I end up getting into an infinite message loop with the WM_GETDLGCODE message being sent/handled constantly. I have tried playing around with the DS_CONTROL, WS_EX_CONTROLPARENT, WS_TABSTOP, and WS_GROUP flags for the controls, pages, and the sheet itself as well as the test dialog, but it still ends up in this loop anytime the ActiveX control loses focus and then regains it (e.g. if the OK button gains focus, but is not clicked or if another program is made active and then I return to my test container).
My test container is very simple:
- Dialog class
---- CWnd wrapper for ActiveX control
Has anyone had this problem or know of a possible solution to it?

I found a solution. As it turns out, Windows/MFC (not sure which) sets the default flags (regardless of what you turn on or off in the dialog template). To get around this, I had to use ModifyStyle and ModifyExStyle to remove the DS_CONTROL, WS_TABSTOP, and WS_EX_CONTROLPARENT flags from the property pages.

Hi there.
I am using
Operating System: Windows XP
Project: Visual Studio 2003 C++ MFC Dialog Based Application
I subclassed an edit box control because I want to capture the WM_KEYDOWN messages when a user enters characters in the edit box. I need this because I want to measure the time interval between keystrokes for the phrase (a password in this case) that the user enters in the edit box.
But I want the user to enter the password twice, once in one edit box and again in another. So I created two edit boxes and then to each edit box added a control variable of type the custom edit box subclass I created.
Now the problem is that when a enter a character in either of the edit boxes, the OnKeyDown function of the subclass is called.
How do I know in which edit box did the user type in the key?
Should I rather create two subclasses for the edit boxes, and create a control variable for the one editbox that is of type: the one subclass, and to the other editbox I add a control variable that is of type: the other subclass?

I have a program that hopefully will update itself. I call
this program Setup.
I execute from Setup.exe the file Update.exe which downloads
Setup.txt. I want to close Setup.exe, delete it, rename Setup.txt
as Setup.exe and then reexecute Setup.exe. The only thing I cant
figure out is how to close Setup.exe from Update.exe.
Please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

Use TerminateProcess(). If the process has a window, you could also post a WM_CLOSE message to that window.

Any chance you have a segment of code that shows how to
terminate a process if you only know the name of the executable
to terminate and where it is located?
So I want to close notepad.exe located in:
c:/temp/notepad.exe
Any ideas?
Please, any response you can give me will be greatly appreciated.

Another way to do this is by having Setup.exe pass Update.exe its main window handle (hex representation as a command line arg). When Update.exe wants to shutdown Setup.exe, it should post a private command (eg: IDC_PLEASE_SHUTDOWN) to Setup.exe's window, which will cause it to exit gracefully. Setup.exe should wait until the window handle is no longer valid before renaming Setup.txt to Setup.exe and executing it.
I admit this method is a bit cheesy, but it works and is safe.

to update applications, use an existing updater...
There are a lot here, but this one is mine. It includes code to close another application (see CInstall::CloseApplication() in Install.cpp). Just copy the code if it does what you need.

So don't bother. Pass the process id of Setup.exe to Update.exe as a parameter, then
a) once Setup.exe has started Update.exe, get Setup.exe to shut itself down
b) the first thing Update.exe does is wait until the process with the passed in process ID is not running (EnumProcesses will help here), then it can do all it needs to.

Hi

template <typename T>
inline bool finite(const & T) { return true; }
template<> inline bool finite<double>(double const & d) { return _finite(d) != 0; }
gives an error
error C2912: explicit specialization; 'bool MLib::finite(const double &)' is not a specialization of a function template (VC7)
I guess I have a syntax error here, or a deep misunderstanding of template specialization (or both). What am I doing wrong?
P.S.
would a
template <typename T> finite(T const &) { return true }
inline bool finite(double const & d) { ... }
work as well?

You have your & in the wrong place. Change the template's param list to (const T& ). (const & T) means "one parameter named T of type const int&".

Hi I am trying to migrate my VC6 MFC Application to VS2005 Beta 2
The App. uses a call to AfxLockGlobals but this function seams to be excluded from the new Version of MFC (V8).
Is there any possibility to use this function or there is any alternative for what this function does?

I have a .dll that i am writing and cannot use standard MFC classes such as CString to parse a blob of data. So i am using std::string but i have never used this before and am so confused. I need to search a string for a key word. Once i find the keyword, i have to parse the data afterwards to pick out the necessary data that i need.
I am using the find method but just stuck and confused to accomplish my goal. Can anyone offer some examples or help? E.g.
If i have a string that looks like
xxxcdfdftbvbfggbnghghg Name: Todd Shields ccfgfgnfgnrri DOB:091580 hgertrtreggeegegggggggggggg
But i want to get the name and the DOB. There is no standard in terms of how much space is allocated for name or DOB. I just have to find it and get the name and DOB from the string.
Any input is appreciated.

Something like:
string s = "xxxcdfdftbvbfggbnghghg Name: Todd Shields ccfgfgnfgnrri DOB:091580 hgertrtreggeegegggggggggggg";
int nPos1 = s.find("Name: ");
int nPos2 = s.find("DOB: ");
string name = s.substr(nPos1 + 5, nPos2 - nPos1);
