I popup the menu and add an event handler of it. Now I am trying to rename the selected tree item.

It is not work in the case of domodal(). The object of dialog is created after calling domodal. So before domodal the exe is crashed because of null dialog object and after the domodal the dialog is already popup. So no any chance to call the above method. Any other way for this?

Thanks it resolved

Can u explain how it is possible or give some link for reference?

The C# dll is already create as per our functionality so it is not possible to change the code of the dll. Is there another way by which I expose the function of C# dll in VC++ by calling function of the dll? If it is possible plz tell me how to do this.

Here also same thing.I am not able to create the com pointer object as you create (ICalculatorPtr pICalc(__uuidof(ManagedClass))).

I read this article but the problem is that in my code I am not able to create com_ptr pointer as created in the given article(MyInterop::IMyDotNetInterfacePtr pDotNetCOMPtr;). Is this problem is persist because of the interface? In my c# code I am not using any of interface object.

Thanx for your help

I used the above code it creates an issue: As first time it creates the window then if I again select the menu it didn't allow to create dialog again. But if I selects the Apply or Cancel button, the dialog closed and after that I select the menu then it didn't allow to create the dialog. It happens till I exit the tray icon. When I start the application again it work and did the same thing as I above explained.

instead of using mutex I directly used FindWindow() method because both are used the Name of the dialog instead of Handle.

No, I can't use or create any process or thread. It is just simple dialog whenever user select the menu it shows that dialog. It is DoModal(), but whenever I click on the menu it creates the new one dialog which is wrong. This menu item is handled from a tray icon, that's why user select that menu item again and again and the new dialog instance get created. How to resolved it please tell me.

I got the handle of the dialog as null. How I get the handle of the window? I used the below code:

void CVTXMIOCaptureDlg::OnContextViewsetup()
{
CEngineSetupDialog *dlg = new CEngineSetupDialog();
HWND hWindow = dlg->GetSafeHwnd();
BOOL bWndAlive = ::IsWindow(hWindow);
if(!bWndAlive)
{
dlg->DoModal();
}
}

I used this but in future if the name of the dialog is changed then this method is not useful. Is there any another way in which I pass the handle of that dialog and then it detect that this dialog is opened or not?

To reduce the memory utilisation.

I have a project in which no. of thread classes are used and my TL tell me that identify which is worker thread and which is user. So that's why I'm asking this.

I make the registry as you say HKEY_CURRENT_USER\\Software\\MYKEY in WinCE 4.0 and then check, this time also I don't get registry value or updated the registry value same is happened for Ini file. What should I do now?

My TL give me another work so I give you reply regarding to this later. Thanks for your help.

I got the answer. Using WriteprofileString or GetProfileString we never update the ini file in eVC 4.0. Because these api's read the value only from the registry. For the ini file can I use any other concept. Please suggest further.
Go on "http://us.generation-nt.com/answer/read-write-ini-file-help-63453642.html" url.

It's not working. I got bResult as true but no updation is done in the ini file

I got value of pApp->m_pszRegistryKey as zero which return the value of pApp->WriteProfileString() as false. Please debug that code and give me answer.
