This could be some dependency issue. Check the dependecy of the DLLs/components associated with this COM DLL and ensure that it's built using 64 bit environment. Check with Dependency Walker[^]tool ( 64 bit version is available).

Also try manually using regsvr

Hi,

Thanks for your suggestion. I ran dependency walker in 2003 64 bit for my dll. it displayed two errors in the following dlls

DEVMGR.DLL
DWMAPI.DLL.

it says "error opening file". Don't we have these dll's along with 64 bit 2003 os?

Regards

I don't know about DWMAPI.DLL but the other one should be there in the system folder. Do one thing, in the 32 bit system, try to track down, from where these files are getting resolved using depends. Then you can try the same thing in 64-bit environment also

Hi Sarath,

I created the application by following the below link
http://www.codeproject.com/KB/shell/shellextguide1.aspx?fid=519&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2469014#modifyingmenu[^]

but the same is not working in my 64 bit windows 2003 server.

How to migrate this application?

Regards

I can't figure out what's really happening there. The IContextMenu inteface should work well with your application. Have properly set set _WIN32_WINNT and WINVER macros? According to your target OS?

is this the following code that i have to make in stdafx.h

#ifndef _WIN32_WINNT NTDDI_VERSION   
#define _WIN32_WINNT NTDDI_VISTASP1  
#endif

#ifndef _WIN32_IE
#define _WIN32_IE 0x0700
#endif

after making the above change i am getting the following error

error C1189: #error : _WIN32_WINNT settings conflicts with _WIN32_IE setting c:\program files\microsoft sdks\windows\v6.0a\include\sdkddkver.h
it is failing here
#if ((_WIN32_WINNT < _WIN32_WINNT_WIN2K) && (_WIN32_IE > _WIN32_IE_IE60SP1))
#error _WIN32_WINNT settings conflicts with _WIN32_IE setting
#endif

I am working on vistasp1

what could be the problem
Regards

Hi,

TO run a web application with 32bit dll in an 64 bit server, just in the IIS, "enable 32-bit application" to true for the application pool. This seting will work almost all servers expect SBS server.

Why don't you use a more recent compiler?

Hi all,

How can I set a partition as active partition using c++ code?
Is there any API or function to do that?

Please guide me with your comments.

thanks.

I suspect DeviceIoControl[^] and the IOCTL_DISK_SET_PARTITION_INFO_EX[^] control code may point you in the right direction. I don't know if they'll actually let you do what you want, though - that function may only be accessible through lower level NT functions that are (publicly) undocumented, or documented in the device driver documentation?

In fact, looking a bit further, I suspect IoSetPartitionInformationEx[^] is probably the function you need - but that's part of the NT API, not the Win32 API.

The details of all installed applications are stored in registry under,
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Since you have a preference for C Compiler, You can use plain windows api to read the registry and populate the list. This article[^] will be helpful.

Jijo.

you can right click on the dialog and select Insert ActiveX Control and select the windows media player activex.

once its selected then create a member variable for it. you get all the wrapper classes that is required for the activex component to work properly.
