Hello,
I have an application that import contacts from outlook contact directory.
there is a problem that when someone has a very big list of contacts the application get stuck for along time until it finish importing the contacts,
I moved the entire import code to a pthread that will handle the import so the application won't get stuck while it's importing.
to access outlook i'm using this code:
hr=pApp.CreateInstance(__uuidof(Application));
when this code is executed from within a pthread it fails, but when executed normally from the application everything is working fine,
Anyone know what causing this problem?
Thanks.

Does that CreateInstance require you to initialize COM before using it (CoInitialize/CoInitializeEx)? If yes, how did you initialize it?

No initialize is needed,
here is the code access the outlook:
void CXPowerUIView::importFromOutlook()
{
_ApplicationPtr pApp;
_ItemsPtr pItems;
MAPIFolderPtr pFolder;
_ContactItemPtr pContact;
HRESULT hr;
try
{
hr=pApp.CreateInstance(__uuidof(Application));
if (FAILED(hr))
{
MessageBox(_T("Unable to instantiate Outlook."),_T("Outlook Error"),MB_OK);
return;
}
...........
}
This are the 2 ways I call it:
direct:
importFromOutlook();
from thread:
outlookHandle = CreateEvent(NULL, FALSE, FALSE, NULL);
outlookImportThread = ys_thread_create(2000, OutlookThreadFunc, NULL);
void* OutlookThreadFunc(void* pParam)
{
pThisView->importFromOutlook();
return NULL;
}
only direct one is working :/

And what does the HRESULT hr tell you? Just a blindshot here, add this to your thread:
CoInitializeex(NULL, COINIT_MULTITHREADED); at the beginning and CoUninitialize at the end. Like:
void* OutlookThreadFunc(void* pParam)
{
CoInitializeEx(NULL, COINIT_MULTITHREADED);
pThisView->importFromOutlook();
CoUninitialize();
return NULL;
}
That _ApplicationPtr::CreateInstance is probably using COM and as far as i know you have to initialize COM in every thread you intend to use it in.

Hi,
I am working on Excel Automation Project.
using GetActiveobject , getting one instance of Excel.exe. But need to track/access any number of instances which are opened.
Initally I am checking all the processes in task manager, if Excel.exe is running, then I will loop through to get the active Excel object using GetActiveObject.
But only one instance I am able to access. How to track other instance of Excel.exe's.
Regards,
KTTransfer.

Do you need the COM instances or just the process handles?

I am working on a similar problem. I know the HWND for each Excel instance and implemented the MFC ActiveX control you mention above. However, I have not used an ActiveX control in C++ before. Do you know how I can get m_pDocDisp? I tried putting just the code above in my native C++ / Excel C API application and it doesn't find it.

Hi All,
I have an application generated by the VS2005 AppWizard so that it has Automation enabled and I've setup the interface so it all works correctly.
However, I also have the app accepting command line parameters when starting from the command line(which it mainly is since it's fired up from a Java servlet).
The app gets called so many times I only want one instance of it to exist at a time so as to cut down on system resource usage.
What I want to do is register the IDispatch of the automation object with the ROT when the app is first started up with the command line. That way when a user starts the app again I can check with the ROT to see if an instance of my app is running. If it is, I just get the IDispatch out of the ROT and pass the parameter values to the running instance via the methods on it. I then shut down my app before I've completed assigning all the necessary resources to it.
So my question is: How do I get the IDispatch to my app if it has been started with the command line?
Thanks very much for any help
Thomas

Hi,
I have single Dialog Templates with all controls using for 3 differnt types.
For Controller-EditBox should be shown
For Indicator-ComboBox should be shown
For Switch-RadioButton should be shown.
So when i invoke dialog for controller it will show editbox,indicator will show combobox .
And What i want, if i invoke controller,then i will invoke indicator without closing the controller.
THis is funcntinality i want.
But what happened,after i clicked controller,when i click indicator it shows edit box only not ComBobox.
If i first open indicator,and then controller shows only ComboBox not EditBox.
How can i get that.
I use UpdateData() in OnInitDialog,But no use.
BOOL CFacePlate::OnInitDialog()
{
CDialog::OnInitDialog();
UpdateData(FALSE);
if(oTagBase->GetTagType()==CONTROLLER)
{
GetDlgItem(IDC_STATECOMBO)->ShowWindow(SW_HIDE);
}
if(oTagBase->GetTagType()==INDICATOR)
{
GetDlgItem(IDC_SPVALUE)->ShowWindow(SW_HIDE);
}
I have lot of controls like this.So i coded only to hide controls and not to show.
Is there any solution?

I would recommend you reading this article.

You have lot of controls?
Why don't you use a function?
Example:
void CFacePlate::SetDlgItemVisible(int idCtrl, int iTagType)
{
if (oTagBase->GetTagType() == iTagType)
{
GetDlgItem(idCtrl)->ShowWindow(SW_SHOW);
}
else
{
GetDlgItem(idCtrl)->ShowWindow(SW_HIDE);
}
}
BOOL CFacePlate::OnInitDialog()
{
CDialog::OnInitDialog();
SetDlgItemVisible(IDC_STATECOMBO, INDICATOR);
SetDlgItemVisible(IDC_SPVALUE, CONTROLLER);
}

I need your Guidance.
Thanks,

The official MFC way is to:
- derive a class from CCommandLineInfo and overide CCommandLineInfo::ParseParam
- call CWinApp::ParseCommandLine in your overide of CWinApp::InitInstance using an instance of your class derived from CCommandLineInfo.
When a new instance of your application starts CWinApp::ParseCommandLine slices the command line into tokens and chucks each on in turn into "YourDerivedClass"::ParseParam. ParseParam can do whatever it likes with the tokens it gets - raise or lower flags, set global state, you name it.
If you want a simple class to explore these concepts try this for size:
class simple_command_line_parser : public CCommandLineInfo
{
public:
void ParseParam( const wchar_t* parameter, BOOL, BOOL )
{
::AfxMessageBox( parameter );
}
};
All it does is display the parameters it recieves in a message box. You'd use it by adding the following two line to your App's InitInstance:
simple_command_line_parser sclp;
ParseCommandLine( sclp );
Anyway, hope that helps!

this makes absolutley no sense as to why this is happening...
Here is the scenerio:
I have an INI file that gets uploaded into some product durring the test.
I have to modify the INI file before upload, so I do so using WritePrivateProfileString(x,x,x,x). Return value is good, no errors.
Read the settings I just changed in the INI file via the GetPrivateProfileString(x,x,x,x), values returned match what I changed them to,
ok, stop there.. (via breakpoint or messagebox)
Now, go into windows explorer and open the INI file and none of the data in the INI file has changed per the write command.
Now, exit the program, or stop it if in the enviornment. Now go and read the INI data from the INI file in windows explorer.. The data is now changed.
Or you can simplely write some data to a bogus file and it will force the INI file to get updated...
OK, now the reason this is such a problem is that after I modify the INI file I have to start the upload process, but I can't because the upload procss graps the file from windows, except the file hasn't been updated yet to the values I wrote using the writeprivateprofilestring command.
This makes no sense to me. Why is windows waiting to update the actual file? Is the a command I need to send to force windows to release the cach so that the file gets updated?
Hopefully someone can explaing what is going on here... Any information will help.. I hope I am so confused by this....

See the description here[^], particularly the paragraph that states:
The system keeps a cached version of the most recent registry file mapping to improve performance. If all parameters are NULL, the function flushes the cache. While the system is editing the cached version of the file, processes that edit the file itself will use the original file until the cache has been cleared.
It's time for a new signature.
