In the documentation for TrackPopupMenu it says that: TPM_LEFTBUTTON Causes the pop-up menu to track the left mouse button. TPM_RIGHTBUTTON Causes the pop-up menu to track the right mouse button. In the following code, changing TPM_LEFTBUTTON to TPM_RIGHTBUTTON does not change anything...

On page 85 of Don Box book, Essential COM, is a code like this: STDMETHODIMP MyClass::UseIt(VARIANT var) { VARIANT var2; VariantInit(&var2); VariantChangeType(&var2, &var, 0, VT_BSTR); ustrcpy(m_szSomeDataMember, SAFEBSTR(V_BSTR(&var2))); VariantClear(&var2); } I am wondering what happens if...

Can someone please explain to me what is the difference between true and TRUE and why we need both of them? There is also a Variant_true ( I probably have a spelling error in this last one) to futher complicate the issue. Thanks

I have a regular dll and try to link to it from a MFC dialog based project. I get unresolved linker error due to the name mangling. I have a .def file in my dll project to export functions. I changed the name of the function ( it is a static function of the dll class drived from CWinApp)to the...

I have an ATL project, that uses MFC. If I link statically to MFC everything is fine, but if I set my project setting to use MFC in a shared DLL, then when I try to bring up a dialog, I fail with an Assertion failure. This is very similar to the problems in coding a dll where one has to use...

When using DCOM and client server on two separate machine, I can start the server in the debugger and set some break points. Then when I start the client, when client makes a request to the server, the server process stops at the break points and I can debug the server. The same procedure does...

I started a simple dialog based project. On the dialog, there is a push button that when pressed brings up another dialog. I use the task manger to watch the memory used by my program. I bring up the second dialog by pressing on the push button and then close it. After I repeat this for few...

I have a client on one machine and server on another. I am logged in on both machine as the user. I am node Admin on both machines. I start the server on one machine and then the client on the other. Client can successfully call advise on the source interface of the server. But, if I don't start...

I have two servers that talk to each other using DCOM interfaces. Although I probably should be using connection point for communication in one of the directions, I do not want to use connection points. Connection in both direction is done through regular com interfaces. Here is my problem: 1...

I have a COM server which contains a dialog box. When I start the server through CoCreateInstanceEx called by a client, the dialog box does not come up. I assume this behavior is caused by the fact that the object, started by the client, does not have access rights to the windows station. Deos...

I have a MFC exe project with ATL support. (VC++ adds ATL support to MFC when you insert new ATL object.) I add some messages to my application using AfxMessageBox for debug purposes. Now, If I run my application in the debugger, AfxMessageBox works and pops up dialog boxes with my messages. But...

I have a VC++ 6.0 program on Windows 2000. I run my program in the debugger and it works fine. But when I start it by double clicking on its icon, after sometime I get an error message: The instruction at "0x0042b1b5" referenced the memory at "0xcdcdcdcd". The memory could...

I have an MFC application with a new ATL Object inserted in it. I have a client running remotely on another machine. If I start the server manually, CoCreateInstanceEx call from client succeeds and everything works fine. But if I don't start the server, CoCreateInstanceEx can not start it...

When you start a new project using ATL application wizard, VC++ creates a makefile for you that you can use to build the proxy/stub dll. However, if you create your server using MFC application wizard, V++ won't create the makefile. Does anybody know how to create proxy/stub for MFC servers...
