Your Dialog Proc for Property page is not returning the values to the property sheet handler. To set the return value, the dialog box procedure for the page must call the SetWindowLong function with the DWL_MSGRESULT value, and the dialog box procedure must return TRUE.

try the following,

case WM_NOTIFY:
	lpnmhdr = (NMHDR*)lParam;
	switch (lpnmhdr->code)
	{
	case PSN_APPLY: 
		SetWindowLong(hdlg, DWL_MSGRESULT, PSNRET_INVALID_NOCHANGEPAGE);
		return TRUE;

	case PSN_SETACTIVE:
		SetWindowLong(hdlg, DWL_MSGRESULT, 0);
		return TRUE;

	case PSN_KILLACTIVE:
		SetWindowLong(hdlg, DWL_MSGRESULT, FALSE);
		return TRUE;
	}

just for checking purpose try the above, read msdn for each Notification and write accordingly.

And also message loop has to check for OK cancel part. read msdn for PropSheet_GetCurrentPageHwnd also.
while (GetMessage(&msg, NULL, 0, 0))
{
if(PropSheet_IsDialogMessage(g_hwndPropSheet, &msg))
{
if (!PropSheet_GetCurrentPageHwnd(g_hwndPropSheet))
{
DestroyWindow(g_hwndPropSheet);
PostQuitMessage(0);
}
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

In visual C project (MFC type) go to insert menu and select bitmap option. Browse for your picture file and add it.Under resources tab in the project navigator check the ID of the bitmap file. Then under OnPaint() function add this piece of code.

CPaintDC dc(this);

CBitmap bmp , *poldBmp;
CDC memdc;

bmp.LoadBitmap(IDB_BITMAP1); // IDB_BITMAP1 is the ID of the bitmap loaded

mdmdc.CreateCOmpatibleDC(&dc);

poldBmp= memdc.SelectObject(&bmp);

dc.BitBlt(10,10,47,47,&memdc,0,0,SRCCOPY);
memdc.SelectObject(poldBmp);

//Do not call CDialog::Onpaint() for painting

I think he wants to insert a image to a control(maybe static control or no).

I think you are looking for Win forms help. Then I think this is not the message board, you have dedicated message board for WF.

Anyway, right click the picture box you have "Choose Image" option in the context menu. Or go to the property View and Image Option has the field to set the Image.

And if you looking for Picture Control in win32/MFC, in the property view, set the type of picture control to Bitmap, and specify the ID of the bitmap resource in the Image field

You can use of this code for insert image to your control.
#include AtlImage.h
CImage m;
m.Load(_T("c:\\1.jpg"));
m_Control.SetBitmap(m_.detach());

What's a "dll application"?

We deal in "processes" here Smile | :)

Do you need to pass a message from one process to another?

If so... Interprocess Communications[^]

error C2440

Hi all,

I am writing this code in VC 2005

TCHAR szPath[MAX_PATH]; 
CStdioFile sys_file_ptr;
GetModuleFileName(NULL,szPath, MAX_PATH);
PathRemoveFileSpec(szPath);

suppose file is located at this path

szPath = C:\New Folder\new.exe

and after using PathRemoveFileSpec() API i am getting this result

szPath = C:\New Folder

i want to add a slash at the end of the string. i do it using this code

szPath = szPath + _T('\\');

it gives error

error C2440: '=' : cannot convert from 'TCHAR *' to 'TCHAR [260]'

i have tried strcat()also but it also gives some error.

somebody can tell me how to do this......

use _tcscat() inplace of strcat, as you are using generic text data type.

You cannot do string concatenation that way with a character array. you must go on with a C-like approach:

_tcscat(szPath, _T("\\"));

Aside from that being syntactically wrong, why not just use PathAddBackslash()?

modeless from modal

Hi everybody!

In a project I am working on I have a modal dialog and I would like to show an other modeless dialog by clicking on a button.
The modeless dialog is created before the DoModal is called, and therefore after clicking on the button (only ShowWindow(SW_SHOW) ) the modeless dialog it will appear, but I can't click on it, because it has no focus.

Have anybody an idea how can be solved this problem?

Thanks in forward.

that is the behavior of Modal Dialog, the user cannot interact with other windows until the dialog box is closed, then you have to go for Modeless dialog instead.
