where m_pPreviewInfo and m_pPreviewDC is protected members of CMyCustomPrintPreview:
CPreviewDC* m_pPreviewDC;
CPrintInfo* m_pPreviewInfo;
of the first sight, I had do something wrong on the above code ? Because when I am trying to use m_pPreviewInfo object in CMyCustomPrintPreview::OnDraw, is crashing and I get an access violation on:
_AFXEXT_INLINE UINT CPrintInfo::GetMaxPage() const
{ return m_pPD->m_pd.nMaxPage; }
Thank you.

I suspect that your CPrintDialog object is going out of scope thus causing this error. You should use new to create it before adding it to your CPrintInfo.
|
|
|
|
|
Yes, that was it ...  Thank you. I am go with one step further ... I come beck soon.

Yes, I had created dinamically (with new), but when I am trying to clean up in my class destructor, it crashing ...
CPrintPreview::~CPrintPreview
{
if(NULL != m_pPrintDlg)
delete m_pPrintDlg; }
weird ...
|
|
|
|
|
Are you sure that your CPrintInfo object still exists at this point?
|
|
|
|
|
I am sure that is not null ... is not enough ? How can assure of CPrintInfo existence ?
|
|
|
|
|
It should be enough, but if it has somehow been corrupted, or already deleted then you will get a crash. The only way to check is via the debugger.
|
|
|
|
|
Thank you Richard, deleteing CPrintInfo object is excluded, the destructor is the only place where I explicity delete this object ... I have to dig in ...

I tried to create a COM component for outlook using article "Building an Office2K COM addin with VC++/ATL". When I register COM, COM added in outlook (display a button in oulook), But If I again open outlook (means 2nd time), COM addin is not there.
What I need to change so that COM functionality should be there untill I unregister the COM component?

Hello Guys.
I have a problem. I have a windows service compiled with various dll's and it includes a project in C++ that contains a reference to Oracle.DataAccess.
The server where that service was installed now has Windows Server 2008 R2 x64. When I try to install the service i get a error in the C++ project. I compiled the project for x64 and now it installs perfectly but when i try to use it i have a BadImage error refering to the Oracle.DataAccess.
I understand that the problem is because the Oracle.DataAccess is x32, but since i can't install oracle x64 in that machine is there anything I can do to make my c++ project run as x64 using the Oracle.DataAccess x32 in the Windows Server x64?
Thanks in advance guys.

You can NOT mix 32 and 64-bit code in the same process. You either have to recompile your app as 32-bit or install the 64-bit Oracle client.
|
|
|
|
|
Indeed.
I had to install the 64-bit Oracle client.
Now I'm trying to config the application to use 64-bit or 32-bit Oracle client according to the processor type using the configuration in the app.config:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess"
publicKeyToken="89b483f429c47342"
culture="neutral"
processorArchitecture="x86" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess"
publicKeyToken="89b483f429c47342"
culture="neutral"
processorArchitecture="Amd64" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
Thanks for your help Dave.

Hi,
I writing a small application which will notify whenever any windows messages or Dialogue boxes appear with any of the (Error,Information,Warning,Question) Icons.
this is how i am doing..
main()
{
WinHAn = FindWindowA(NULL,"Windows Security");
if(WinHAn != NULL)
{
EnumChildWindows(WinHAn,SearchIcon,(LPARAM) &winIconSearch);
}
}
static BOOL CALLBACK SearchIcon(HWND hwnd, LPARAM lParam)
{
style = GetWindowLongPtr(hwnd, GWL_STYLE);
if ((style & SS_ICON) == SS_ICON)
{
thisHan =(UINT64)SendMessageW(hwnd, STM_GETIMAGE,IMAGE_ICON, 0L);
searchHan =(UINT64) LoadIconA(NULL, (LPCSTR)(IDI_WARNING));
if(thisHan ==searchHan )
{
printf("Icon Found");
}
return TRUE;
}
This is only for Warning messages.But it is not working. can any body tell me what the problem is..
Thanks.
vvk.

You might add some more output to your program to see which code is reached or use the debugger for the same purpose. E.g. if a window with the title "Windows Security" is found and if such a window contains a static control with an icon.
Your check for SS_ICON is wrong (but this is not the reason for finding nothing). You should use:
if ((style & SS_TYPEMASK) == SS_ICON)
Finally I'm not sure if this can be done this way. While the LoadIcon description states that it may return a handle to an existing resource, this may be only true when the icon has been loaded by the same application.

Stepping through your code with the debugger will identify where it is failing. Have you checked that there is a currently open Window with the title "Windows Security", to satisfy the FindWindowA call? By the way, it is really bad practice to use the A or W suffixes on your Windows API calls. Use the project settings to set your project to ASCII or Unicode mode, and let the compiler generate the appropriate code.

Hi,
i have tried with debugging and the it is failing at the if condition if(thisHan ==searchHan).Sendmessage function('thisHan') is returnig one value and where Loadicon function is returning('searchHan') different value.
|
|
|
|
|
So the icons don't match. All that tells you is that the icon for the message window is not the one you were hoping for. The chances of you being able to use this code in a production environment are not very high, since very few applications will be doing things the way you expect or want.

Hi,
My application menu items which are created dynamically. When window DPI settings gets changed and set to 'Larger (150%)', menu item text is not visible as it is very big and hiding behind the toolbar.
How can we set menu item font size or complete menu pane itself using VC++ by code so that it will be visible in all the DPI settings?
Regards,
Aniket

Have you looked at the GetMenuBarInfo function? You can get the RECT of the menu-bar with this function.
I.e
MENUBARINFO mbi;
mbi.cbSize = sizeof(mbi);
GetMenuBarInfo(hwnd, OBJID_MENU, 0, &mbi);
printf("menuBar rect (screen) = %d,%d,%d,%d\n", mbi.rcBar.left, mbi.rcBar.top, mbi.rcBar.right, mbi.rcBar.bottom);
MapWindowPoints(HWND_DESKTOP, hwnd, (LPPOINT)&mbi.rcBar, 2);
printf("menuBar rect (client) = %d,%d,%d,%d\n", mbi.rcBar.left, mbi.rcBar.top, mbi.rcBar.right, mbi.rcBar.bottom);
Notes:
1. All of the members are 0 during the WM_CREATE message handler
2. The dimensions returned are in screen-coords.
Example output:
menuBar rect (screen) = 108,130,636,149
menuBar rect (client) = 0,-20,528,-1
When I tried to change the DPI setting with the program running, I was told I'd have to logoff and then login again. Am I correct in assuming that you change the DPI and _then_ open the program?
Also, is this a standard menubar, or is it an instance of a toolbar that's been added to a rebar control? The difference being that a standard one should be a part of the non-client area, and therefore the toolbar you have should be automatically moved down to accomodate the menubar having larger text.
If however, you have a toolbar inside a rebar control as your menu, the rebar container is a part of your client area, and you need to manually position the toolbar below it. Different DPI settings will change the required height that you need to offset the toolbar by.
Can you upload a screen shot somewhere and post a link to it?

Hi,
i have developed an application in which i have icons in left side pane of application which can be dragged and dropped in client screen. Application is working fine with all the resolution except 1920x1080.
when setting the resolution to 1920x1080 while dragging icons to client area, icon is not attach to mouse pointer. instead there is a gap between the mouse pointer and the icon. i wrote code to identify the screen resolution but it does not seem to recognize 1920x1080 resolution. below code is giving incorrect resolution for 1920x1080 setting.
RECT actualDesktop;
GetClientRect(GetDesktopWindow(),&actualDesktop);
value of 'actualDesktop' variable is {top=0 bottom=783 left=0 right=1536} which is incorrect. according to current resolution size value should be {top=0 bottom=1080 left=0 right=1920}. Due to this, all the icons while dragging are adjusting according to incorrect resolution setting.
Can someone help me to identify the issue and let me know if there is any limitation with respect to screen resolution in VC++ 6.0 with windows 8 environment.
If require i will place more detailed code about the drag and drop functionality.
Regards,
Aniket

That may well be your problem; VC 6 is very old and probably has many issues with Windows 8. I strongly suggest you upgrade to the latest version of Visual Studio.

Hi,
Thanks for replying.
But i am getting same issue when compiling in VS2012 in windows 8. code does not seem to recognize 1920x1080 resolution setting and downgrading my application look and feel by setting it to lower resolution.
Any help would be appreciated.
Regards,
Aniket
