That was the first link. It's about using metafiles with Win32 APIs (No MFC) and includes a downloadable sample...

for (int i = 0; i < arraySize-1; ++i)
{
cout << array[i] << ", ";
}

cout << array[arraySize-1];

Right, but don't forget to test for the empty array condition. The for loop checks it itself, but the last sentence may attempt to access array[-1].

Okay, I have a dialog, made with the resource editor, im using it as my main window, and im using Pure Win32, no MFC!, and i want this dialog to be positioned by the system like a normal window would be if you had created the window with CreateWindow() and specified CW_USEDEFUALT for the X paramater, but i dont know how to get my window to do this.

and please, if you dont know exactly what i am asking then dont bother trying to answer

Position the dialog to your liking in response to the WM_INITDIALOG message. Use:

SetWindowPos(..., CW_USEDEFAULT, CW_USEDEFAULT, ...);

for the x and y parameters.

MoveWindow(x,y,cx,xy)

tried this, it positions the window off screen

Does MoveWindow() produce the same result? I'm not sure if either support CW_USEDEFAULT.

You might want to explain this requirement further. Perhaps there's a better alternative.

ADO Seek method

Hi,

I am trying to use the Seek method in an ADO recordset object. It works fine if the index is only one field. For an index with multple fields, say two strings, I cannot seem to make it work properly.

MSDN says that the first argument is a Variant array.

example code:
_variant_t varKeys[2];
varKeys[0] = "value1";
varKeys[1] = "value2";
m_pRecordset->Seek( varKeys, adSeekFirstEQ );

What happens is that only the first value seems to taken into account.

Any ideas ?

note: I am using an MDB (Access) database. Opening using Jet4 conenct string.

thanks,
Louis.

It seems like rather than an array of variants, what you need is a single variant containing an array of values.

Check this article[^].

If I have a class made in my MFC application I am making I get a very fun bug. This also happens if i call delete on an object I have allocated and of course even though a memory leak when a homemade class goes out of scope.
So tell me how can i make a class or use delete on objects or eve my own classes? Here are my linker errors:

Prog error LNK2005: "void * __cdecl operator new(unsigned int)" (??2@YAPAXI@Z) already defined in libcpmtd.lib(newop.obj)
Prog error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in LIBCMTD.lib(dbgdel.obj)
Prog fatal error LNK1169: one or more multiply defined symbols found

Isn't that great? So i narrowed it down to creating a class and it going out of scope as well as the call of a destructor or even just deleting a simple character array.

I suspect the problem is your sytnax when you call new and delete. It obviously thinks you're trying to define these operators, or at least that they are multiply defined elsewhere.

Try creating a brand new project, and adding a char * with new and delete in your main. If that doesn't work, your compiler setup is screwed. OTherwise, your project is somehow screwed.

Obtain a handle to a label in a container

Hey there,
I have an application which has a "ThunderRT6UserControlDC". There are various control within this container such as
1. A drop down box
2. Label box
3. Gifs
4. a List View

For some reason 1 and 2 are not visible as having handles when viewed from Spy++.
I need to get the handle to the Label box (2) to retrieve its text. I'm trying to access this from a different program so I have to use handles and cannot use properties withing my application.
Any suggestions!!
Abhishek

Are they obscured by some other control like a groupbox?

Hey David,
I'm not sure ..... the ThunderRT6UserControlDC is a child of ThunderRT6PictureBoxDC which contains a number of ThunderRT6UserControlDC's. However I don't think its obscured. If it were it would have shown up in Spy++ ( is assume).

One possible reason for those controls not appearing in Spy++ is that they might not be separate windows. The drawing and behavior of those controls might be implemented directly inside ThunderRT6UserControlDC.

Is that a VB app? I seem to remember reading somewhere that VB implement some basic controls entirely by its own without creating actual Win32 windows for them. That would explain what you are seeing (and what not) in Spy++...

hey Jose,
If they are implemented directly inside ThunderRT6UserControlDC, do you think there is some way of extracting the text.....using a Gettext or something.......because I am not sure if that would work since the there seem to be subcomponents with different structures (like the drop down compared to a text box)

No, if that is the case, I don't think there is a way to get the text.

But maybe you can find something googling for ThunderRT6UserControlDC or asking in a VB forum...

Hey all

Ive created a API modeless dialog inside of a DLL, and is created whenever the calling program calls the appropriate exported function. In a past thread that i posted, this dialog would cause the application to lock up with the not responding dialog. Thanks to someones tip to use DefWindowProc() I can now get the dialog to work (pops up, and close button properly closes when clicked), only it appears to not be responding to move messages (the message called when i would like to drag the dialog around on the screen).

From DLLMain:

<br />
hDLL = hinstDLL;<br />

The exported function that starts the dialog:

<br />
<br />
//mWnd is handle to main window of calling program<br />
//aWnd is handle to active window (programm calling is MDI)<br />
<br />
int __stdcall WINAPI x(HWND mWnd, HWND aWnd, char *data, char *params, BOOL show, BOOL nopause){<br />
<br />
	MSG msg;<br />
<br />
	hDlg = CreateDialog(hDLL, MAKEINTRESOURCE(IDD_DIALOG1), mWnd, (DLGPROC)DlgCallBack);<br />
<br />
	ShowWindow(hDlg,SW_SHOW);<br />
<br />
	while (GetMessage(&msg, NULL, 0,0)) {<br />
          TranslateMessage(&msg);<br />
	  DispatchMessage(&msg);<br />
        }<br />
}<br />

The DLGPROC:

<br />
LRESULT CALLBACK x(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam){<br />
	switch (uMsg) <br />
    { <br />
		case WM_COMMAND:<br />
<br />
			switch(wParam){<br />
				case IDOK:<br />
				DestroyWindow(hDlg);<br />
				return TRUE;<br />
			}<br />
<br />
			break;<br />
 <br />
        case WM_DESTROY: <br />
            DestroyWindow(hDlg);<br />
        PostQuitMessage(0);<br />
            return TRUE;<br />
    }<br />
<br />
	return DefWindowProc(hwnd, uMsg, wParam, lParam);<br />
}<br />
