MSVCRT...

28-Sep-01 11:51

Hey all!

I compiled an ATL ActiveX Control DLL using Visual C++ 7 - and noticed that the DLL depends on MSVCRT70.DLL...

I have several questions:
1. Can I somehow remove this dependency?
2. What's in that DLL anyway?
3. Suppose I will compile the code with Visual C++ 6 - it will depend on MSVCRT.DLL, right?
4. Is it possible to remove THAT dependency?
5. Is there any software that comes with MSVCRT.DLL EXCEPT for Visual C++? (Internet Explorer, or Office, or something common like that?)
6. Suppose I want to distribute that file along with my ActiveX Control (for download on a web page) - will it work from the control DLL's directory? Need I put it in the user's Windows\System directory? Need I do anything else? Is it legal to distribute this DLL just like that?

Thanks a lot! Smile | :)

In VS.NET (VC 7), right click on your project in the Solution Explorer and choose properties. The General tab has an option fo "Minimize CRT Use in ATL", switch this to Yes and you should statically link to the CRT's.

If you build it with V6, if you use the min_dep project configuration you will statically link to the CRT's and no longer require that DLL.

You can distribute that DLL with your ActiveX Control and put it in the same directory as your control and that should work.

Hi,

I think you can't send characters, only virtual keys.
You may do the conversion with VkKeyScan.
Don't ask me details, 'cause I never tried Smile | :)

Hi,

In one of my programs, I am trying to shutdown windows. The following code works well under W2k but it does not work under WinME/9x. It starts the shutdown process, it closes all windows and then hides the taskbar but then it stops.

Please help. Is there any problems with the code?

PS. The reboot operation works well.

<br />
int CTaskStep::ExecuteShutDown ( CTaskObject *pTask , bool bReboot)<br />
{<br />
	HANDLE hProcess = GetCurrentProcess(); // Is pseudohandle, no close needed <br />
	HANDLE hToken = NULL;<br />
	OpenProcessToken(hProcess,TOKEN_ADJUST_PRIVILEGES,&hToken);<br />
	if ( hToken ) <br />
	{<br />
		TOKEN_PRIVILEGES priv_struct;<br />
		LUID_AND_ATTRIBUTES priv;<br />
		LUID priv_luid;<br />
		BOOL bRet;<br />
		bRet = LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &priv_luid);<br />
		priv.Attributes = SE_PRIVILEGE_ENABLED;<br />
		priv.Luid = priv_luid;<br />
		priv_struct.PrivilegeCount = 1;<br />
		priv_struct.Privileges->Attributes = SE_PRIVILEGE_ENABLED;<br />
		priv_struct.Privileges->Luid = priv_luid;<br />
		bRet = AdjustTokenPrivileges(hToken, FALSE, &priv_struct,NULL,NULL, NULL);<br />
		CloseHandle( hToken );<br />
	}<br />
	if ( bReboot )<br />
	{<br />
		if(!ExitWindowsEx (EWX_REBOOT | EWX_FORCE,0) )<br />
			return MSG_FAILED;<br />
	}<br />
	else<br />
	{<br />
		if(!ExitWindowsEx(EWX_SHUTDOWN | EWX_POWEROFF | EWX_FORCE, 0))<br />

Hello, the codegurus around the world.;)

IE consists of iexplorer.exe and the other core dlls like Wininet.dll.
Each IE seems to be the different versin of dlls files.
So, if IE5.5 has this kind of bug, this bug must be come from the bug of some dll.

If you read the bug list of IE5.5, you may find this bug in that bug list?
Or, if Javascript checks the version number of these dlls,
you may write the code to prevent this bug after you add the new code? Confused | :confused:

Have a nice day!

DLL and ATLTRACE question

28-Sep-01 6:59

Hi
I'm new to ATL. Now I wrote a DLL and compiled it in release mode.
I other DLLs I saw the macro ATLTRACE(_T("Some trace message"));

What does this macro do and how can I find out whether this macro has been "triggered" Confused | :confused:

ATLTRACE is just like the MFC TRACE macros, they only print to the output window in debug. In release mode they do nothing.

Function with variable number of argument

28-Sep-01 6:42

Suppose there is an existing function (not written by me) with the following signature:

void OldFun(...);

I want to write a new function as follows:

void NewFun(...)
{
// do something
// then call the existing function with the given arguments
OldFun(...)
// do something else
}

The question is, how do I pass the parameters? Passing ... doesn't work.

Please help !!!

Thanks.

void NewFun(int param1, int param2, ...)
{
	va_list argptr;
	va_start(argptr, param2);

	OldFun(argptr);

	va_end(argptr); 
}

you need at least one fixed parameter

How to get the desktop background image ?

28-Sep-01 6:38

Hi,

I would like to create a window which always stands above the desktop background, ie below all other windows. Because this window may have alpha transparency, I need to get the desktop background to be able to bitblt it in my window. How to perform that ? I tried to get the fullscreen DC with GetDC(NULL) but if other windows are opened when creating mine I don't get the desktop image but simply the windows which cover the screen.
Thanks for any help or pointer to information.

How can add buttons in a win32 applicatios?

Hello,

I was wondering how I can add buttons to a win32 application?
I have used MFC extensively, but never just straight win32, and I was
wondering how to add buttons in Win32? Or other controls for that matter.

Thanks in Advance! Smile | :)

Re: How can add buttons in a win32 applicatios?

Erik Hammar28-Sep-01 7:38

Erik Hammar

I (think) this should do it:

HWND button = CreateWindow("button", "(Your Caption)", WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, buttonx, buttony, buttonwidth, buttonheight,
hWndParent, NULL, hInstance, NULL);

hWndParent is your dialog or window, where you want the button
buttonx, buttony, buttonwidth, buttonheight is the buttons position in the dialog
"button" is the class name for a button control
the style "BS_PUSHBUTTON" creates a standard button. "BS_CHECKBOX" creates a check box.

I have created a SDI project without Doc/View support.
So I got the following classes WinApp, CMainFrame, CChildView.

Now I got 2 questions how do I add controls to the CChildView which I guess is the view I see when I run the project?

Second how do I add a new view and shows it? Can I use CFormViews?

If anyone know any sites that describes this please let me know.

Cheers

Re: Basic question

I guess, that when saying "add controls to the cchildview" You mean creating some wnd's like on dialog?
If yes, then You need to derrive Your CView class from CFormView. CFormView needs IDD of the dialog (unique identifier). Then, Your application will display dialog in view.

But If this is really Your goal, maybe it would be better to create dialog application, not MDI/SDI app.

In order to add new views, You will need to create splitter, either dynamically or statically. You can find complete help in MSDN along with samples.

Hi
I'm developing an application that have a List Control inside.
I would like to receive the "return key pressed" event, but I don't see how to do this.
I use the LVN_KEYDOWN notification but it detects all the pressed keys exception for the return key. Confused | :confused:

!?...

If someone have experienced the same problem and/or know how to solve it I would be very appreciated if you reply it for me.

TIA.

Try handling the WM_GETDLGCODE message, and add DLGC_WANTRETURN to the default implementation's return value.
