In the IDL file it should be [in, out] SAFEARRAY(VARIANT)* oAxisComponentsArray
In the .h and .cpp files it should be SAFEARRAY** oAxisComponentsArray

Superman,thanks a lot.
Could you please tell me how to realize the SAFEARRAY(VARIANT) oAxisComponentsArray with C++, and how to write InvokeHelper?

I record audio with several microphones and I need to know the microphone that I used with each recording.
Can anyone help me? How can I identify the microphone in the recording?
Is there a command or something like that?

Hi,
I am facing a problem with IWshRuntimeLibrary::IFileSystem. It is working fine on Win2003,Vista 32 bit. But fails in Win2008 std sp2.
I am using following function from IWshRuntimeLibrary::IFileSystem
1.CopyFile
2.GetFolder
3.FileExists
4.DeleteFolder
5.CreateFolder
I am currently using VC++.
Why IWshRuntimeLibray::IFileSystem is failing. Can I have any alternate solution.
|
|
|
|
|
Please debug and check the reason for failure
but i have the alternate solution as to suggest you to use SDK APIs
CopyFile :: Copies an existing file to a new file.
CopyFileEx :: Copies an existing file to a new file.
CreateDirectory :: Creates a new directory.
CreateDirectoryEx :: Creates a new directory with the attributes of a specified template directory.
CreateFile :: Creates or opens a file object.
DeleteFile :: Deletes an existing file.

This may not be an answer to your question, but the easiest way to do this is to place a picture control with a bitmap of the text with the required font size over the group box.

You mean some text inside the groupbox or the caption of the groupbox? If the caption of the group box, you could rename the ID of the group box such that it is NOT IDC_STATIC and then add a control variable to it (say m_GroupBox) and then call m_GroupBox.SetFont();

I m already try this but its not done.

OK, try this code:
CFont f1;
LOGFONT lf1;
::ZeroMemory(&lf1, sizeof(lf1));
lf1.lfHeight = 16;
lf1.lfCharSet = ANSI_CHARSET;
lf1.lfWeight = FW_BOLD;
::lstrcpy(lf1.lfFaceName, "Arial");
f1.CreateFontIndirect(&lf1);
GetDlgItem(IDC_GROUPBOX)->SetFont(&f1);
f1.Detach();
Obviously you'll have to change some things to make it work with your code but you'll get the idea.
Edit:
Actually, you might want to clarify first what Rajesh asked:

Hi all,
In my program, I have the following statement:
ISearchResultPtr spIsr = spWuSearcher->Search(criteria);
Most of time, the program will excute successfully, but when "criteria" is _T("UpdateID='12345678-9abc-def0-1234-56789abcdef0'"), then spIsr->Updates->Count is 0, but not 1 which is the right value.
Is there anyone who knows why or when this happens?
NOTE: I'm sure the "UpdateID" is right.
Any reply is appreciated.
Thanks a lot

Is there any way to find out which logical drive is in use by windows or is opened in Explorer in C++ ?

If my pointer is pointing an invalid object. How to find proactively in run-time.
|
|
|
|
|
there are some memory check functions as _CrtIsValidPointer()
It is strongly recommanded to avoid this situation. use pointers to data, only for copying the data, if you need it later. -> make your own object 
Press F1 for help or google it.

To check the validity of the pointer in Windows there are API functions called IsBadReadPtr and IsBadWritePtr to do that.
P.S. While using pointer developer should be careful that pointer is set to NULL once it is deleted. And not to use the deleted pointer before allocating memory.

There is no reasonable and fool proof way to make this check.
You as a programmer must ensure that this never happens.
Smart pointers can help you to an extent.
