It's not that he mean, I know what he mean because I've seen that before too!
Sometimes intelli sense stop working. When you type "object." or "object->" you'd expect that VC will show a menu with all members etc. But it doesn't.

I don't know why it does like this, but sometimes you just need a restart of VC and sometimes a restart of the whole system.

I have also tried deleting the NCB file. I am not sure if that really helps.

Sometimes closing VC and reopening helps.
Sometimes closing VC, deleting the *.ncb, *.opt and *.pos files in your Project dir and repoening helps.
Sometimes you simply have to live with it.
Especially when using levels of pointers casted into another type, you can easily ask too much of the poor parsing code.
Maybe it gets better with VC7?

That usually works for me.

Hmm I'll try deleting them. I didn't know about opt and pos files, just tried deleting the NCB.
Thanks to everyone who answered

Close the workspace (or solution if you're using VS.NET), delete the .NCB file, and reopen the workspace/solution. Deleting the .APS file will also help with problems with the resource editors sometimes.

Printer Driver

Hello everybody!

I've got a customer asking for a Windows printer driver that can render the output into a compressed TIFF image file.
I've never written a printer driver before so I am looking for pointers in the right directions.
My requirements are that it should be a regular Windows driver (98/Me/NT4/2000/XP) and it should work exactly like a standard printer driver with the difference that the output has to go to a file instead of a printer.

Any help is highly appreciated. I guess someone has already made a library or some source code of a skeleton of a driver like this. The main problem I see is grabbing the output sent to the driver and decode it and find out its format.
Thanks!

Ehehe

I've already done the same query on google, but all I've found are precompiled drivers like this one. But I need to do a lot of customization on this project. I described only the base of the project, but there's going to be a lot of other little stuff going on, so I cannot use a 3rd party driver. Frown | :(

hello, i have a callback MouseProc function that's not being called, what's wrong? thanks
LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lparam){
ofstream output1("debug.txt",ios::out);
output1.write("hello",strlen("hello"));
output1.close();
return -1;

}
HOOKPROC hookproc = (HOOKPROC)GetProcAddress(hInstance, "MouseProc");
SetWindowsHookEx(WH_MOUSE, hookproc,hInstance,GetCurrentThreadId());

the following is the main function in detail:
int PASCAL WinMain(HINSTANCE hInstance, HINSTANCE hPrev, LPSTR lpCmdLine, int Cmd) {

MSG msg;

// Setup and register the window class;

WNDCLASS wClass;
wClass.style =CS_HREDRAW|CS_VREDRAW;

wClass.hbrBackground =(HBRUSH)(COLOR_WINDOW+3);
wClass.lpszMenuName =NULL;
wClass.lpszClassName =WINDOWNAME;

RegisterClass(&wClass);

// Create the window and store the handle;

Getting Print Dialog colour settings and resetting DIB pallette

Anonymous20-Dec-02 2:55

20-Dec-02 2:55

I'm using a DIB and StretchDIBits to print a bitmap to various printers. My problem is that, when I'm printing to a printer that supports only black & white only the very dark colours are visible in the printout. I'm not sure how to, first of all check for printer colour settings and secondly how to then set up the Pallette to support black & white settings. Confused | :confused:

Is there anyone who can offer any advice. Even pointing me in the right direction will be much appreciated.

I don't understand. You said "usually", have you found an exception to the rule? If so, rest assured that such an anomaly will not last for long!

Try setting the style "Clip children" in the resource editor for yor main window (or if it is not a dialog, set the style WS_CLIPCHILDREN when creating the window).

dialog app

Raphael Kindt20-Dec-02 1:05

Hi
I open a simple modal dialog box... (from a menu)
And I want to do this:
When the mouse cursor move above a simple component (CEdit, CCheckBox, CComboBox, etc.), I want to display some information about this component fonctionnality (CEdit, etc.) in CEdit with the read-only flag...
The WM_MOUSEMOVE message is sent to the dialog box. Here is the code I use:

void CControlDlg::OnMouseMove(UINT nFlags, CPoint point) 
{
	CWnd* ThisWnd = ChildWindowFromPoint(point);
	int ThisID = ThisWnd->GetDlgCtrlID();

	switch(ThisID) {
	case IDC_TPG_V_H:
		m_strInfoControl = "Test Pattern Generator for incremental test";
		break;
	//
	// + some other case for different component information
	//
	default:
		m_strInfoControl = "default";
	}
	UpdateData(FALSE);
	CDialog::OnMouseMove(nFlags, point);
}

The m_strInfoControl is the information display into an Edit box read-only component...
The problem is that the dialog box loses the control of the mouse when the mouse cursor is above a component...

Thanks in advance...

You could compare the coords or the cursor (the point parameter of OnMouseMove) with the CRect coords of the control with CRect::PtInRect ... Unsure | :~

?

[EDIT] I might have not understand your question : Is it you can't recognize the control where the mouse cursor passes over, or is it you cannot do anything after you recognized it ?
