I'm getting an internal compiler error C1001. Microsoft says it's a bug. More information on the bug can be found here[^].

The internal compiler error (affectionally called ICE) means just that the compiler crashed for whatever reason. It is a bug in the compiler, simply put. There are tons of situations leading to an ICE, at least in MSVC 6.0. Some of these situations involve valid C++ code (that usually is too complex for MSVC), and some other situations involve illegal C++ code. Even in the latter case, the problem remains primarily with the compiler, as crashing is not a reasonable response to a program, incorrect as this might be. At least, you still have the chance to try to determine by yourself what the problem in your code is and try to get the compiler back to sanity.

In this particular case, I think your code is wrong. The line

static const MYSTRUCT *myStruct[];

declares an array of pointers to MYSTRUCTs, while

{{0, 0, 0, 0}}

looks more like an array of MYSTRUCTs. Could this be your problem?

Also, the MSKB article you refer to is just a situation leading to an ICE, but I don't think it has anything to do with your particular problem.

Hello,

Thanks for your reply. The problem was indeed with my code using a 2D array of pointers. After I rewritten the code using 2 seperate arrays (one of pointers, one of MyStructs), it works perfect.

Anyway, here is the solution of the problem:

<br />
class a : public CMessageBase<br />
{<br />
private: <br />
static const MYSTRUCT* MyStructs[2];<br />
static const MYSTRUCT MyStruct[]; <br />
};<br />
// initialize the array here<br />
// if I remove this line, no error occurs<br />
const MYSTRUCT* a::MyStructs[] = {NULL, &a::MyStruct[0]};<br />
const MYSTRUCT  a::MyStruct[]  = {{/*Some values*/},{/*Some values*/}};<br />

Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

you are declaring an array of pointres to mystruct. you cannot initialize them to zeros(to NULL yes ) but not zeros. or so am lead to believe.

Have 0 (zero) and NULL suddenly become different?

Not necessarily. C1001's can be caused by lots of things. Most likely, the compiler is getting confused by other errors that it hasn't had a chance to print out yet.

Is there any reason why you're not giving the array a size? Try giving it one and see if that works.

Also, I'm not sure you can initialise a pointer to a structure with the {} method. Is your intention above to initialise the array to 4 pointers pointing to NULL? If so, you've got too many {'s - just use { 0, 0, 0, 0 }.

Hello,

I think that the thing I was trying to do is impossible the way I wanted to, leading to incorrect syntax. After rewriting the thing, solution posted above, it works like a charm.

Thanks for your help. Big Grin | :-D

Dialog accelerators

Hi!

I have created a dialog-based application, and I want to create accelerators. For example, when the user presses F2 key, I want to show the aboutbox dialog.

In the OnInitDialog function, I added the following lines:

<br />
// Accelerators<br />
	HACCEL m_hAccel=::LoadAccelerators(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_ACCELERATOR));<br />
	ASSERT(m_hAccel);<br />

m_hAccel is defined as HACCEL.

Also, I added the following member function:

<br />
BOOL CCRDlg::PreTranslateMessage(MSG* pMsg)<br />
{<br />
	if (m_hAccel != NULL && TranslateAccelerator(m_hWnd, m_hAccel, pMsg))<br />
		return TRUE;<br />
<br />
	return CDialog::PreTranslateMessage(pMsg);<br />
}

My Resource definition is defined like this:

<br />
/////////////////////////////////////////////////////////////////////////////<br />
//<br />
// Accelerator<br />
//<br />
<br />
IDR_ACCELERATOR ACCELERATORS <br />
BEGIN<br />
    VK_F2,          ID_ABOUT,             VIRTKEY, NOINVERT<br />
END

But this code doesn't work, my accelerators don't generate a WM_COMMAND.....

What's the problem?

Thks in advance!

You cannot expect other member functions to have access to this local variable. The variable must belong to the class.

Hi!

I'm looking for a way to draw transparent Slider controls, instead of drawing it with a grey background.

Is there a message to handle like other control (WM_CTLSTATIC,...)?

Can anybody let me know if there is a way to change the caption name on a button (if you were using another language), without changing the dialog.
In other words can you read the caption names from a file?
Smile | :)

Many thanx

Cool | :cool:

Yes, you certainly can. After reading the button's caption from the file, use SetWindowText() to change its caption. Many apps that allow you to switch the GUI language at run time (not just startup time) use this method.

The label of a button can be set with SetWindowText. In order to get the HWND of a given button, you might want to use GetDlgItem. Is this what you're atfer?

I would like to SEE THE CODE that will diaplay text to a device context (i.e. the window's client area) with each letter a different color.

Can I do it w/ a CString?

How to use the DrawText or TextOut call to get each letter a different, possibly random RGB() value? Confused | :confused:

Blake Miller6-Oct-04 9:59

If 'hc' is less than zero, the hook procedure must pass the message to the CallNextHookEx function without further processing and should return the value returned by CallNextHookEx. You should not even try to interpret the incoming data if 'hc' is less than 0.

Did you hook WH_MOUSE_LL or WH_MOUSE ?

Rename file to Unicode name

I want to rename a file to have a Unicode name using Windows Base Services. I thought MoveFileW(wSrc,wDst) would do this, but since the source file name is not Unicode, I can't get MoveFileW to recognize it. I have tried converting the source name to Unicode. MoveFileW() reports no error.

OK, MoveFileW() really DOES work.
When copying UTF8 characters to a wchar_t array, be sure to call them unsigned. Otherwise the UTF8 characters >127 will sign-extend to the high byte of the wchar_t.
