hello,I wrote a property named get_Popvalue(long *nValue),
STDMETHODIMP CATC:get_Popvalue(long *nValue)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
// TODO: Add your implementation code here
*pVal = m_dSendBytes;
TRACE1("m_dSendBytes:%d\n",m_dSendBytes);
//m_dSendBytes is not changed here??
return S_OK;
}
and m_dSendBytes is a public variable the defined in the class CATC.
m_dSendBytes will be changed in another function CATC:NotifyData()
void CATC:NotifyData(long nSize)
{
m_dSendBytes += nSize;
//m_dSendBytes can be changed here
}
but m_dSendBytes can not get correctly by com invoked.
Can you tell me why? Thanks

*pVal = m_dSendBytes;
Here pVal is not declared in the code. The function parameter declaration is nValue and not pVal. The posted code shud not complie. if it is a typing mistake, then chk the IDL declaration for the property. Other than the variable name change issue, the code code you posted doesnt have any error.
cheers...mil10.

I am using the STL list container to hold objects of class a. Class a has various member variables of standard type(int, char, etc.). All variables are public. How would I go about accessing those variables in order to compare one object to another?
This is some of my actual code.
void ProcessFile(string filename, std::queue<cjob> &jobQueue)
{
char jobID = 'Z';
int numJobs;
int priority;
int arrivaltime;
int cpuburst[2];
int ioburst[2];
int i;
// ofstream constructor opens file
ifstream injobFile( filename.c_str(), ios::in );
ifstream injobFile1( filename.c_str(), ios::in );
// exit program if unable to create file
if ( !injobFile )
{ // overloaded ! operator
cerr << "File could not be opened" << endl;
exit( 1 );
} // end if
cout << "Reading file..." << endl;
/* //Count number of jobs by counting occurrences of \n
numJobs = static_cast<int>( std::count( std::istreambuf_iterator<char>(injobFile1),
std::istreambuf_iterator<char>(), '\n' ) );
*/
char crap = '(';
//input from file;
i = 0;
//Job * ptrarr_Jobs[10];
while ( i < numJobs)
{
injobFile >> crap >> jobID >> priority >> arrivaltime >> cpuburst[0] >> ioburst[0] >> cpuburst[1] >> ioburst[1] >> crap;
CJob tempJob(jobID, priority, arrivaltime, cpuburst[0], ioburst[0], cpuburst[1], ioburst[1] );
//tempJob = new CJob(jobID, priority, arrivaltime, cpuburst[0], ioburst[0], cpuburst[1], ioburst[1] );
jobQueue.push(tempJob);
cout << "(" << jobID << ' ' << priority << ' ' << arrivaltime
<< ' ' << cpuburst[0] << ' ' << ioburst[0]
<< ' ' << cpuburst[1] << ' ' << ioburst[1]
<< ")" << endl;
i++;
} // end while
return ; // ofstream destructor closes file
} // end ProcessFile()
Notice I referenced the queue; I am having trouble accessing the CJob objects' member variables when I am in the calling function...(main() in this case).
Thanks for any help.

Hi,
I'm trying to use the CAxWindow class to create a runtime control in a CDialog box. I have no problem creating the control but how can I call the methods of the control.
Thanks

Hi Michael,
The problem I'm having is my Active(ocx) control does not have any interface pointers. All I have is dispinterface for the ocx. Do you know how I call the methods of this control.
Thanks
|
|
|
|
|
You'll be calling it through IDispatch. Use IDispatch::GetIDsOfNames to map method names to IDs, then use those in IDispatch::Invoke. To discover what methods are avaialable, use IDispatch::GetTypeInfo.
Have a look at the source for CComDispatchDriver::Invoken in the ATL that comes with VC++ 6 for some guidance.

I am a beginner.My first program is show a picture on one static control which based on dialog!And I use WTL to do it,is there some example code ?
Or which book shoud I read!
Pre_thank you for give me a direct!My english is very poor,sorry!Just can read some comment!
I will online wait for you today!
heboy, the name is same as my real name!its meaning is "river "

I have a series on WTL starting here[^], however it probably won't be too helpful if you have no Windows or GUI programming experience already.
I always advise newbies to start at the API level, and not to move on to libraries until you have a very good understanding of how the APIs work.

Hi all,
I am using ATL COM application, in which i am having a list control, i want that by clicking the particular column the elements of that column sorted out how can i do it ...Plz help me out
I write one callback function for sorting and i called that function in the OnColumnClickListname handler i share my code
LRESULT OnColumnclickList1(int idCtrl, LPNMHDR pnmh, BOOL& bHandled)
{
// My code started here
m_ctrllist.Attach(GetDlgItem(IDC_LIST1));
HD_NOTIFY *phdn = (HD_NOTIFY *) pnmh;
m_ctrllist.SortItems(SortFunc, phdn->iItem);
m_ctrllist.Detach();
//My code ends here
return 0;
}
static int CALLBACK SortFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)
{
int nRetVal;
PITEMDATA pData1 = (PITEMDATA)lParam1;
PITEMDATA pData2 = (PITEMDATA)lParam2;
switch(lParamSort)
{
case 0:
nRetVal = strcmp(pData1->empcode,
pData2->empcode);
break;
case 1:
nRetVal = strcmp(pData1->empname,
pData2->empname);
break;
case 2:
nRetVal = strcmp(pData1->designation, pData2->designation);
break;
default:
break;
}
return nRetVal;
}

Use CSortListViewCtrlImpl, it does sorting for you.

Hi
I'm using ATL just for one function.
Base64Encode.
I don't make server or network i want juste Encode a string.
I try to make it with an example
from CodeProject:
CString sSource = "ToEncode";<br />
<br />
int nDestLen = Base64EncodeGetRequiredLength(sSource.GetLength());<br />
CString str64;<br />
Base64Encode((const BYTE*)(LPCSTR)sSource, sSource.GetLength(), <br />
str64.GetBuffer(nDestLen), &nDestLen);<br />
str64.ReleaseBuffer(nDestLen);<br />
cout<<(LPCSTR)str64;
It said me Cannot convert CString to LPCSTR one first argument of Base64Encode.
I'm working under VS2005.
It's the right way to do what i want?
Is there a better way, maybe something else than ATL?
How to correct this error?
Thanks for your answer.
Sorry for my poor english i'm not an english-speaking

Hi all,
I am using ATL wizard to make my ATL application and i have ClistCtrl and i want to sort the list,How can i do this if any one having any idea please share it,it will be very thankfull to me
Thanks in advance
|
|
|
|

By default CListCtrl will sort items in ascending order.
You can control sort order programatically by setting the style LVS_SORTASCENDING or LVS_SORTDESCENDING

Just use CSortListViewCtrlImpl, that's all.

i am new with ATL , i want to declare a method which have a out parameter, i am decalaring this like
[id(1), helpstring("method calcution")] HRESULT calcution([in] int ival1 ,[in] int ival2,[out] int& iret);
but i compiled this is giving errors like
syntax error : expecting a declarator or * near "&"
syntax error : expecting ) near "&"
please give me answer as soon as possible.

IDL doesn't have references. Try this:
[id(1), helpstring("method calcution")] HRESULT calcution([in] int ival1, [in] int ival2, [out, retval] int *pRet);

Hi,
How Do I implement late binding on a COM Addin which I created using ATL?
Thanks..

Implement the IDispatch interface. Here's the IDL file for an AddIn I implemented for VC6
import "oaidl.idl";
import "ocidl.idl";
[
uuid(0c8dd9f0-2391-447a-b6dd-72aea4db9dc4),
version(1.0),
helpstring("Visual C++ Build Environment Loader Add-In 1.0 Type Library")
]
library DSWENVLib
{
importlib("stdole32.tlb");
importlib("stdole2.tlb");
importlib("devshl.dll");
importlib("ide\devdbg.pkg");
[
uuid(01b836c6-51c8-4476-bf15-ae91b0fe74f6),
oleautomation,
dual
]
interface ICommands : IDispatch
{
[id(1), helpstring("method RereadEnvironment")]
HRESULT RereadEnvironment();
};
[ hidden, uuid(0309A24D-B3E7-4C6A-8ACD-B3F0F8FAA483) ]
coclass ApplicationEvents
{
[default] dispinterface IDispApplicationEvents;
}
[
uuid(6c5658bc-946b-4bc7-94bf-5530cad3d654)
]
coclass Commands
{
[default] interface ICommands;
};
[
uuid(3d3eb2a1-8ce9-4555-89cd-d989a6b3009e)
]
coclass DswEnv
{
[default] interface IUnknown;
}
};
If you pick the correct options when creating the class, all the hard work gets done for you

Thanks a lot for your answer.
But if my Idl is smething like this then...
import "oaidl.idl";<br />
import "ocidl.idl";<br />
[<br />
object,<br />
uuid(23BB6C3D-AF30-4622-AE80-F19B29A964A7),<br />
dual,<br />
helpstring("IOutlookAddin Interface"),<br />
pointer_default(unique)<br />
]<br />
interface IOutlookAddin : IDispatch<br />
{<br />
<br />
};<br />
[<br />
uuid(B6AE2F8A-DA59-4371-8664-D4DEFCBE60C9),<br />
version(1.0),<br />
helpstring("EOutlookAddin 1.0 Type Library")<br />
]<br />
library EOUTLOOKADDINLib<br />
{<br />
importlib("stdole32.tlb");<br />
importlib("stdole2.tlb");<br />
<br />
[<br />
uuid(6228A6E9-3C8C-4E6C-8869-77631F65164A),<br />
helpstring("OutlookAddin Class")<br />
]<br />
coclass OutlookAddin<br />
{<br />
[default] interface IOutlookAddin;<br />
};<br />
};
Plus I also have
#import "C:\Program Files\Microsoft Office\Office\mso9.dll" rename_namespace("Office") named_guids <br />
using namespace Office;<br />
#import "C:\Program Files\Microsoft Office\Office\MSOUTL9.olb" rename_namespace("Outlook"), raw_interfaces_only, named_guids <br />
using namespace Outlook;
in my StdAfx.h file. I think the moment we use #import the dlls get early binded, isn't it?
I am creating an Outlook addin. So can you show me the way to create a late binded Outlook addin using ATL.
Thanks once again...

Ah - you mean you want to late-bind to Outlook?
In that case, you're correct - the #imports early-bind. You need to access the relevant object through it's IDispatch interface. Not very much fun...You might find using a wrapper around an IDispatch pointer (like this[^]) makes things easier.

|
|
|
Why do you want to bind late? I tought the office components were dual, and can thus be called through the vtable.
