This is code in DLL
wchar_t* CEngDLL::GetStringResourceID(DWORD dwResID) // This function return resource string
{
// CString str;
wchar_t myString[300];
HINSTANCE hInstance = AfxGetResourceHandle();
AfxSetResourceHandle(::GetModuleHandle(L"NSEngDLL.dll"));
LoadStringW(hInstance,dwResID,myString,300) ;
return &myString[0];
}
Following code in client application
BOOL CEngTestDlg::OnInitDialog()
{
CString msg;
CDialog::OnInitDialog();
msg = obj.GetStringResourceID(10);
m_lblExample.SetWindowText(msg); // for loading string from DLL
//other code
}
void CEngTestDlg::OnOK()
{
UpdateData(true);
CString resStr;
//wchar_t* resStr;
resStr = obj.GetStringResourceID(100);
MessageBox(resStr);
// TODO: Add extra validation here
//CDialog::OnOK();
}
when i debug DLL it run fine but when i run client application there is error msg as "Application.exe reference memory x0000000.. could not read memory" so plz guide about this error.
Thanks

u r returning an address of locally define object. this is a wrong implementation. Cause the
wchar_t myString[300]; will get destroyed as soon as u return from the function GetStringResourceID.
u should allocate it in heap.
wchar_t* CEngDLL::GetStringResourceID(DWORD dwResID) // This function return resource string
{
// CString str;
wchar_t* pmyString = new wchar_t[300];
HINSTANCE hInstance = AfxGetResourceHandle();
AfxSetResourceHandle(::GetModuleHandle(L"NSEngDLL.dll"));
LoadStringW(hInstance,dwResID,pmyString,300) ;
return pmyString;
}
dont forget to delete the pointer in the client app.

I need to print from a C++ application using the custom form. It is possible to set user defined paper length and paper width to this custom form. Addition of custom form from the application using AddForm function worked fine. But it was not possible to change the printer settings (paper size) using this custom form. Is there any method by which this can be achieved. I tried with ::DocumentProperties function to get the printer properties.
The reference link to microsoft knowledge base is http://support.microsoft.com/kb/282474
How can we change the printer settings using custom form settings. Please help.
Thankyou

Thanque for u r reply
here iam pacing the bitmap in Richedit like chatting emotions.here the requirement is add tooltip to that bitmaps on recieving side.

derive a class for the richedit( or u have to do it in the PreTranslateMessage function of the dialog )
overide the WindowProc function and call the RelayEvent of the tooltip from it( u need to create an object of CTooltip in that class)
Also overide the mousemmove message of the richedit control. In that function Check the mouse is over the bitmap, if yes call AddTool function of the tooltip with the message that you want to display. If it is not over the bitmap remove the tooltip using DelTool.

Which bit are you stuck on ? ( at least you found the right forum ). Did you download the PSDK and look into directshow, as I suggested ?

Do you mean compare a picture with one taken earlier to see if it has changed ?

Hello everyone,
My general question is about Commercial Software Application. Are they (Commercial Software Applications) are also designed using the same Good Old Win32 APIs or they use a different approach?
Base on what I have learned on the last few days, I would say YES as long as they are supposed to use Windows Operating System. But I would like to hear your expert opinion on this, please.
Thank you,
Khoramdin

If they run on Windows then yes they use the same good ol' Windows APIs, directly or indirectly.
The Windows operating system is the only layer between application code and the hardware.
Even if you only use the generic C Runtime Library (CRT), the version of the CRT for Windows maps
all hardware-related stuff to Windows APIs.

Is there any way to deny focus to an application?
Trivial example: non-focused (MFC) application with a single button (might have to implement as label) that, when clicked, sends a Unicode string (example “\u8000”) to the application (e.g. excel, word, notepad) that does has the focus.
Behaviorally, with these 3 applications and the desired non-focused application on the desktop, the user could switch among the applications and send the string to each when the non-focused application is clicked.

By the time the button is clicked, your app (and not Excel, Word, etc.) has focus. I recommend caching the currently active (non-self) main window every few mSec and targeting it when the user presses the button.

What about handling the WM_MOUSEACTIVATE in the button's parent window and returning
MA_NOACTIVATE (I haven't tried it)?

Many thanks for all the suggestions...they were very clever.
I ended up using the WS_EX_NOACTIVATE style in creating the window, and that worked just fine.
thanks again.

Hello,
If I am not mistaken the Spy++ should be available when I have my Visual C++ window up and running.
unfortunatly, I am unable to see this options. I believe I should have it under "TOOL" option, but when I check this menu option I cannot see it!!!
Could you help out regarding SPY++?
Thank you for your time,
Khoramdin
