i guess you need to have STL at workplace search for it and place it in visual studio, i guess thats it. If not then earch for the particular file it needs and showing doesn't exist and cut paste the code into a file and add it to project. that's it. u r done..

In french, this is called a "bulldozer solution" Poke tongue | ;-P

More seriously, the error is caused by an #include<new> which is precisely different from new.h, i guess, and i do not where it is.

I definitely think i'll have to compile at home Cool | :cool:

Thanks very much for your help.

Maybe one of your comuters is in urgent need of a newer platform SDK?
Or the "ProjectSettings-Tools-Options-Directories" settings are broken?

Hope this helps / Ich hoffe ich konnte Dir helfen!

In the Development of ActiveX control using VB we have a property called "EditAtDesignTime", is there any similar property like this in VC++ ActiveX control ?

i dont know what u r exactly looking for,, but i have a trick.. you know the length of your edit box, i mean how many chars it can hold, then calculate the length of the strig it contains, now minus the length of total string that is the actual length you can see use CSting and getright(this value) you get the char at this position from right.

{
    if(CanOpenPortOnHostUsingWinsock(lpszHost, i))
    {
        ShowMsgPortIsOpen(lpszHost, i);

Check the docks for info on Winsock functions.

Show my dialog outside the Win2k "locked" screen...

Hey,all...

My current Win32 application would do some background job while Windows enters the "screensaver" status, and it would shows a top-most dialog outside the screensaver's screen for displaying the working status and progress.

But now I encounter a problem: while the option "On resume, password protect" is set on the screensaver setting dialog in Win2K/XP, the dialog box on my application cannot be showed outside the screensaver screen, but if this option is not set, it do.

Does anyone can tell me how to solve this problem? Thanks!

The screen saver runs in its own desktop, so windows created by programs running as your account are not visible. It's the same with the Winlogon desktop (the one you see after you stop the screensaver), it's a separate desktop and your windows won't appear there either.

You could write a screensaver that displays your progress.

Hi

I have successfully built a Win32 Static library. I test this by adding the *.lib name to my link option in the project setting but when i try to use the class in the library in the test program, it always give me errror say "Undeclare identifier" whether i know firmly that it is nothing wrong with the declaration. I know that the linking process is ok, but what else did i miss ??

Regard,

Hello,

you have to include the header file where you declared your class you want to use everywhere you plan to use that class. This is needed to make the class known to your application.

dear all,
i'm using Windows Xp pro with NTFS partition.
i've used LogonUser to get a token of a user and then I use the token in CreateProcessAsUser(...). I use flag LOGON32_LOGON_INTERACTIVE SO THERE IS NO NEED TO DUPLICATE THE TOKEN.
I've also set the reqd. previliges in the system.
but still when i try to execute a process, i get an error -> Access Denied (5).

I also tried to use function ImpersonateLoggedOnUser(..) (which was successful) but still I get the same Error while using function CreateProcessAsUser(...) after using ImpersonateLoggedOnUser(...) and the process is not executed.
I've even tried setting priviliges by code and manually in the OS
But still I found the same Error (error number 5).

In VB also i get the same problem. Confused | :confused:

is it a bug!!!!!!!!!!! Suspicious | :suss:

any ideas!!!!!!!!!

thanx,

I'm not even sure where to begin, I highlighted in red the section where I believe it blows up....

#import "Tester.tlb"

using namespace Tester;

class CTestDlg : public CDialog
{
	DECLARE_DYNAMIC(CTestDlg);
	friend class CTestDlgAutoProxy;

// Construction
public:
	CTestDlg(CWnd* pParent = NULL);	// standard constructor
	Tester::_Numbers *com_ptr ;

CoInitialize(NULL);
<font color="red">Tester::_NumbersPtr p(__uuidof(Tester::_Numbers));</font>
com_ptr = p;
long i = com_ptr->GetDay();

The message that pops up says: "Runtime Error! The application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information." Where does and error message like that come from? Confused | :confused:

Should be

Tester::_NumbersPtr p(__uuidof(Tester::Numbers));

The constructor always takes the CLSID of the class not IID of the interface.

I tried this and it looks like this now:

CoInitialize(NULL);
Tester::_NumbersPtr p(__uuidof(Tester::Numbers));
com_ptr = p;
long i = com_ptr->GetDay();
AfxMessageBox(i);

However it throws an error in appui1.cpp. What file is this, I have never heard of it.
