I'm passing an HBITMAP between an application and an out-of-process server.
If the HBITMAP is from a device compatible bitmap, the application displays it correctly.
If the HBITMAP is a DIB section, it displays as a black rectangle the same size as the bitmap.
Any ideas?

I am developing a COM exe using ATL in VS 2005.
On my build machine( XP Pro) , I am able to successfully run the application (debug version )however when I copy the exe to another machine (XP Pro) the exe cannot run .
I get an error message
"The application has failed to start because the application configuration is incorrect . Reinstalling the application may fix this problem"
I have no clue about this error .
Help is appreciated !

First thing, you cannot distribute debug version of your program.
Then, you need to install the run-time libraries and MFC libraries on the target machine. For that, you can execute vcredist_x86.exe on the target machine (you can download it from here[^]).
The link I provided is for VC2005 standard. If you installed the SP1 for VC2005, then look at the links at the bottom of the page, there is a similar download for SP1.
This will install the release versions of the libraries, so you need to distribute a release version of your program too.

I've taken source code from several samples on the web, created a new class library project, and compiled it but I'm only getting a .dll file output, not the .tlb file regasm needs.
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop.

I have an Activex control which exposes multiple interfaces for example,
ISample1 – CSample1 (Coclass)
ISample2 – CSample2 (Coclass)
I need to add new methods/properties (a new version). Since ISample1 and ISample2 cannot be modified, I’ll have two new interfaces,
ISample1Ext
ISample2Ext
These will be a replication of ISample1 and ISample2, but with new methods/properties added. The old interfaces will be marked deprecated and may be removed in future.
The question is, can I still use the classes CSample1 and CSample2 as CoClasses for ISample1Ext and ISample2Ext and modify them to implement the new methods/properties?
If this new version of the control is copied to the client m/c, how will it affect the applications that are using the old version of the control?
If I try to insert this control in an application, which version will be inserted? Also, how do you differentiate between the old version and the new version?
Thanks

Hello,
I have a problem with calling my COM server. It connects and runs successfully with my development box, but crashes on another box.
On the other box, a CoCreateInstance call like:
CComPtr<imyclass> p;
hr = CoCreateInstance(CLSID_MyClass, NULL, CLSCTX_ALL, IID_IMyClass, reinterpret_cast<void**>(&p));
succeeds. Also calls to e.g. p->QueryInterface are ok. But if I call my own methods, it crashes with an access violation / null pointer. The problem is, that I cannot see, where the null pointer is. I don't know, which information I should provide, in order to help someone help me, so please ask anything.
Code is plain C++ with no .NET. Dev Box is a Win XP system, other box a Windows Server 2003 SP2.
To explain a bit more: The null pointer seems to be inside of the com call, since when I debug both client and server, the breakpoint inside of the server is not reached. The error message I get is "Unhandled exception at 0x00000000 in bin.exe: 0xC0000005: Access violation reading location 0x00000000." when I call p->Init(CComBstr, int) (The string is allocated correctly).
I'm pretty confused and don't even know where to start looking. Searching with something like "atl com access violation" or similar doesn't help.
Thanks in advance!

Solved:
The client was not linked with the server.LIB from the server. The .LIB was in the same directory, when the client was launched on my development box, but I've only used the EXEs on the 2003 OS. Linked the client with the LIB and everything workes fine.

Hi everybody!!
I've done some research on the msdn about the WebBrowser control, but yet I can't find what it is. I can see the properties, events and so on, and by the way it's used i think it might be an ActiveX, but I'm not sure.
So can anybody tell me if it's actually an ActiveX, and if gets registered when Windows is installed? Also, is it used by IntenetExplorer in any of its features?
Please, if someone can help me out by explaining this to me or giving me a link to a page where all of these is explained, I will really appreciate it.
Thanks

Hi Kenia,
The WebBrowser control provides a managed wrapper for the WebBrowser ActiveX control.

Dear All,
Unable to convert CString to BSTR! Am I a stupid?! 
I have an interface method which needs to convert CString to BSTR and return BSTR to caller.
AllocSysString of CString is not copying the data to BSTR.
STDMETHODIMP CTP_Interface_ErrorCode_Wrp::GetAdditionalDataFlag(BSTR *AddDataFlag)<br />
{<br />
AFX_MANAGE_STATE(AfxGetStaticModuleState())<br />
<br />
<br />
CString temp = pTP_Interface_ErrorCode->GetAdditionalDataFlag();<br />
*AddDataFlag = temp.AllocSysString();<br />
<br />
return S_OK;<br />
}
Any one please help me.
Thanks very much, Nani
