You've got a circular reference problem.

You can't forward reference a class object, but you can forward reference
a class object pointer, since the compiler knows what a pointer is.

Something like this should work...

// dialog1.h : header file
//

#pragma once

// forward declaration of dialog2 class
class dialog2;

/////////////////////////////////////////////////////////////////////////////
// dialog1 dialog

class dialog1 : public CDialog
{
public:
   dialog2 *d2;

...

};

// dialog2.h : header file
//

#pragma once

#include "dialog1.h"

/////////////////////////////////////////////////////////////////////////////
// dialog2 dialog

class dialog2 : public CDialog
{
public:
   dialog1 *d1;

...

};

Changing visual elements in another dialog class doesn't sound
like a good design.

Maybe send or post messages instead. Let each dialog class change its own
visual elements.

FormView SDI App - Resolution

Member 4431372-Aug-08 0:31

Hi,
I have a SDI FormView based app which contains some custom control along with some standard controls. The problem I am facing is briefly explained below.

I designed the FormView Dialog on a computer which has 800*600 resolution. When I run the app on the same computer the screen is OK. But when test the same app on a computer that has a resolution of say 1028 * 768, the total app window occupied only 70% of the screen.

I have seen one program which has different user interface depending on the screen resolution. It contains more controls on the form if scrren resolution is more or switches to normal form when the resolution is set to lower say 800 * 600 .

I am trying to implement the same behaviour like displaying extra controls if resolution is more, or the important ones for normal resolution.
1. Is it possible using Visual C++ 6.0 version.
2. Does creating two dialog templates one for high resolution, other for low resolution, and loading the dialog depending on the resolution work ?.

regards,
Shanmukha

varChunk.bstrVal = _bstr_t(cWafer); // cWafer is a char array about 2500 bytes long
// for some strange reasons, cannot save varChunk to database and no exception error was capture

LogOnUser fails on Win 2k

Hi,
I am trying to impersonate a user on Win 2k machines. The LogOnUser() api works perfect on XP, 2k3 but it fails on win 2k machines as it requires SE_TCB_NAME privilege. So i tried to set the privilege to the current process by the code available on MSDN http://msdn.microsoft.com/en-us/library/aa446619(VS.85).aspx[^] but it didnt work for me. still it fails by giving error 1314 (A required privilege is not held by the client), if i give the "Act as a part of operating system" privilege from Administrative tools -> local Security Policy -> Local Policy to that particular user, the code works perfectly on win 2k. But how to achive it through code.

Thanks,
Sandeep

I believe that the OP indicated that he could successfully split his view into two columns. He wants to remove/hide one of those panes when a toolbar button is clicked.

Hi,

I am dovelping a wizard based applcation with 3 pages. At one page CTreeCtrl is there but when I call DeleteAllItems() It does not show any item even if I insert the item code is here:

CTreeCtrl *Tree=(CTreeCtrl *)GetDlgItem(IDC_TREE1);
Tree->DeleteAllItems();
Tree->InsertItem(_T("aa"));

And One CComboBox that does not drop down. what is the reason?

Try calling UpdateWindow() after the InsertItem method.

In ComboBox, after dropping the control from the resource pane into your dialog, you have to resize it vertically to set its dropdown area. Click on the pulldown button of the combobox. You will get a fram with 8 resizing points. Resize the frame vertically and try.

Check your resource ID's (IDC_TREE1). GetDlgItem() will return any child control on the dialog with that ID, even if it is not a tree control. The DeleteAllItems() and InsertItem() member functions of the CTreeCtrl class only send messages. If the window they are sending those messages to is not a tree control, it will just ignore them.

This could also explain your CComboBox problem as well.

I have nothing that explains how I can send my program's database data to a known Excel 2007 file. Does anyone know of a tutorial on this; or have any suggestions as to go about it. I tried using the "INSERT" statement but only got one piece of data into the Excel "Sheet", there are 11 colums in the MS Access database and I would like to have those same columns in the Excel workbook. Am I supposed to create a Table with the columns in Excel before trying to transfer the data from Access in my program?

Hello all,

I have some questions about the windows console. If my main GUI windows create a new console windows attach to the main process by calling AllocConsole(). Is there any way to get notify when the console get closed by the user? For example, the close windows button in the top right get clicked by the user. The problem what I have is that if the console windows get closed, then my main process will also be terminated. However, it happen without letting my free my application resource. Any suggestion? Thanks for advance!

Detect if an Application is Playing any Sound

I need to write a program to check if an application is playing any sound through the sound card.
Has anyone had any experience with this? What library should I hook?

This is for Windows XP. The program can be built on any platform (.NET, C++).

I've tried hooking kernel32.DeviceIoControl but I don't know which functions to look for to intercept the Wave output (format and buffers). Should I hijack the sound card drivers? Or is there an easier way?

I appreciate any ideas or thought.
Thanks.
