Use CreateProcess if you want more control over process being spawned
Somethings seem HARD to do, until we know how to do them.

What does RPC or MIDL has to do here?  You want to learn RPC or just run an executable?
If you need to run an executable, you just need ShellExecute or CreateProcess as someone already said.

From MSDN[^], i found STORAGE_DEVICE_DESCRIPTOR is declared in header file - Ntddstor.h. So check whether you've included it or not.
Regards,
Jijo.

Check whether the signature of CMy4Dlg::GetDisksProperty() is exactly same in header and in cpp file?

Hello everyone,
I am inserting vb activex control in VC program.In VB ocx program i am passing variables of type recordset from database.when i am inserting this ocx into my VC program those recordset datatypes are converting as LPDISPATCH* type. and my variables of type CRecordset. it is giving error like this:
C:\Program Files\Microsoft Visual Studio\My Projects\RecordSetPgm\RecordSetPgmDlg.cpp(255) : error C2664: 'Processattendacne' : cannot convert parameter 1 from 'class CRecordset' to 'struct IDispatch ** '
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
VB ocx Code is like this:
void C_UserControl1::Processattendacne(LPDISPATCH* rs, LPDISPATCH* rs1, BOOL* blnprocess)
{
static BYTE parms[] =
VTS_PDISPATCH VTS_PDISPATCH VTS_PBOOL;
InvokeHelper(0x60030000, DISPATCH_METHOD, VT_EMPTY, NULL, parms,
rs, rs1, blnprocess);
}
And VC++ Code is like this:
database.Open(NULL,false,false,sDsn); // Open Clients.MDB
CRecordset recset( &database );
SqlString="SELECT field1 FROM sample";
recset.Open(CRecordset::dynamic,SqlString,CRecordset::readOnly);
CRecordset recset1(&database);
Client= "SELECT field2 FROM sample";
recset1.Open(CRecordset::dynamic,Client,CRecordset::readOnly);
m_UserControl.Processattendacne(recset,recset1,bstr);
database.Close();
please tell me what type of parameters i have to take and how should i declare those please tell me...please Help me out..i am trying this but i am not getting...please give me some suggestions..

CRecordset is an MFC class which is not IDispatch compatible. VB ActiveX method that you are using, requires an IDispatch interface as parameter. If you use ActiveX Data Object (ADO) instead of CRecordset class then you will be able to pass the object to your VB ActiveX methods. I have included the link to samples in my previous post. These will help you get started.
I hope this helps.

Hi All
I want to develop a USB Small project which show all information about USB Device like USB Device name,drive name and file or folder name.Plz help me..
|
|
|
|
|
|
|
OK. So you are using SetupAPI to query USB information. I believe, once you get hold of the device you can use the regular CreateFile, ReadFile, FindFirstFile etc API
