The print resolution of the printer (typically 600 pixels per inch) is much greate r than that of the screen (typically 72 pixels per inch) so you must use StretchBlt if you want it to appear tyhe same physical size on the higher resolution device.

My problem is not to start dialog hidden or create a tray icon, my problem is to do that only at windows startup .
I want that when windows starts the dialog was simply launched in tray .

Yes right !
Now you can implement same by using this logic,I Believe you starting you Application at windows startup using key stored in Registry location RUN.
Now to distinguish wheather the USer is Starting the Program by Clicking over it or Windows is Starting it at start up, you just provide a command line argument to that reg Location i.e. store application path as
c:\\your_app_path\\app.exe -hidden
Now When ever Windows start your application at startup offcourse, you will get -hidden as commandline argument, now you just have to parse the command line [use GetCommandLine() : to retrieve command line arguments]to hide or unhide your application.
There can be other solution also, It's upto you to choose better one.

I've also thought about that , but i did'nt know this function GetCommandLine().
Thanks, so you say that when i add the value to regedit (for my app started at startup) , in my value settings i'll simply write as progra path :
"c:\\myapp.exe -hidden" , and then when i call CommandLine() in OnInitDialog(), if it returns "hidden" , it means my app's started at startup.
Thanks i'll try it

Nope, It will return Application path + Command line Arguments, Something like this "c:\\myapp.exe -Hidden" .
From it,You have manually parse the "-Hidden" command line argument.

My application in my view, is getting quite large, now I have just got a Stack Overflow when I added new code.
If I comment out this new code, the program run OK.
Are they any setting that I can make to increase the programs parameters like Stack size etc to allow me to continue to add to this program.
Note the point in the code that causes the Stack Overflow is a bit strange in the debugger; a simple if statement keeps looping like a while loop.
Any comments please.

i'd advise you to split your code into functions you could include into DLLs...

Are you saying that they are no settings that I an make.
I will do a re-design later, but need this phase to continue.
I assume I have the default settings for Visual Studio (V7.1) being applied.

The default stack size is 1MB. Check out the linker's /stack option.

Hi
I am writing a software for a STAND-ALONE SYSTEM which should expire exactly after 30 DAYS.
The problem is i have to compare my installation date with the system clock , which can be changed easily .... effectively the user can run the software forever if he keeps changing the system date back.
The only solution i see is ... logging the time and date at regular intervals to a file ... probably encrypt it .
but that will also fail ...
Is there ANY other way?

I have edit controls in the property page.How can I capture the OnChar event for the edit controls.
I was told to do that by deriving CEdit class and capturing the OnChar event then.Can anoyone clarify exactly how this can be dealt with.

Use ClassWizard (Ctrl+W) to derive a new class from CEdit.

I have inherited a class from CEdit as show below
class CEditValidate : public CEdit
{
DECLARE_DYNAMIC(CEditValidate)
public:
CEditValidate();
virtual ~CEditValidate();
protected:
DECLARE_MESSAGE_MAP()
public:
afx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags);
};
Now can u let me know how I can use this OnChar handler for validating the characters keyed into the edit control in my property page.

Simply modify that method to allow/disallow the characters. You did not specify what characters you wanted to keep/discard.

I get what you say. But the OnChar handler is not invoked at all when I type characters into the Edit control in my property page. I dont understand how to use the newly inherited class for my edit control in the property page.
