Just call RegisterWindowClass in constructor of dialog. Think you don't need to call XTPResourceManager()->SetResourceHandle

Hi Oleg and Serge,

Thank you for your help.

If I add the CReportControl::RegisterWindowClass() to the dialog constructer and the dialog is displayed.

I tried to change the source code to use 'XTPResourceManager()->SetResourceHandle(hRes)' instead of the above but, it didn't work. It seems that the application cannot replace the resource handle.

sample: 2006-01-17_014739_Sample.zip

Is there any way to solve this problem except using the new RegisterWindowClass?

Thank you.

Sanji.

Hi Sanji,

There is no need to change library source by yourself.
In this case just change the following string in your Sample.cpp:
    if (NULL != hRes) AfxSetResourceHandle(hRes);
to
    XTPResourceManager()->SetResourceHandle(hRes);

Please note that the ReportControl (and others) use XTPResourceManager to load resources instead of MFC or API functions.
For more details see CXTPResourceManager class documentation.

in last versions we added parameter

BOOL CXTPReportControl::RegisterWindowClass(HINSTANCE hInstance /*= NULL*/)
{
WNDCLASS wndcls;
if (hInstance == NULL) hInstance = AfxGetInstanceHandle();

to allow call it with another instance.

I can only suggest you to change sources now.

Hi,

The dialog that include "Report" control doesn't display, if I use the resorce dll which I created for local use.

So far, I found that if I register the "Instance handle" and "Resouce Handle" to the windows class in CXTPReportControl::ResigterWindowClass, this problem does not occur. (Please see the code below)

Do I have to do some thing special if I want to use the external resource file?
I don't want to change the Xtream library by my self.

Thanks,

Sanji

*1). I attach the code to see the problem. 2006-01-16_025026_Sample.zip (See the "readme.txt")

*2). If I made the following changes to "CXTPReportControl" (see below), the dialog displays.

----------------------
BOOL CXTPReportControl::RegisterWindowClass()
{
WNDCLASS wndcls;
HINSTANCE hInst = AfxGetInstanceHandle();
if (!(::GetClassInfo(hInst, XTPREPORTCTRL_CLASSNAME, &wndcls)))
{
  // otherwise we need to register a new class
  wndcls.style             = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
  .....
}

// <<<< Added following code... >>>>
hInst = AfxGetResourceHandle();
if (!(::GetClassInfo(hInst, XTPREPORTCTRL_CLASSNAME, &wndcls)))
{
  // otherwise we need to register a new class
  wndcls.style             = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
  .....
}

return TRUE;
}
