did u miss the IMPLEMENT_DYNCREATE() macro in the cpp file of the property page? Put the following code in your cpp file just after the #includes...
IMPLEMENT_DYNCREATE(CNSPropertyPage, CPropertyPage)
|
|
|
|
|
i think that is not the problem i added correctly as
IMPLEMENT_DYNCREATE(CNSVirtualcircuitPath, CNSPropertyPage)
|
|
|
|
|
ok.
Have you added the file that contains the class CNSPropertyPage into the project? I mean, just take the file view tab and confirm that the cpp file is listed there.
|
|
|
|
|
i properly added that .h file in header file of CNSVirtualcircuitPath
but that file is in different DLL is there any communucation problem i am getting
|

If the body is in another DLL then you need to use dllexport and dllimport to tell the linker to put it into the DLL .lib file. Add the following code to your header file
#ifdef BUILDING_DLL/// export Dlls
#define SDK_EXPORT __declspec(dllexport)
#else
#define SDK_EXPORT __declspec(dllimport)
#endif
and then declare your class as follows:
class SDK_EXPORT CNSVirtualcircuitPath
{
...
}
Define BUILDING_DLL as a proprocessor define in the DLL project (and only in this project)

you mean the CNSPropertyPage is another dll? if so you definitly have to export the CNSPropertyPage class...

ASdd this to the dialog by right clicking on the dialog..
Properties->General->Menu->IDR_MENU1

Create a menu in the resource editor. Select dialog properties. there you will find an entry for Menu. Specify the resource id of the menu that you created. Compile and run. if everything is ok you should see the menu
Somethings seem HARD to do, until we know how to do them.

How to know a function/API is deprecated by Microsoft?
I am using midiOutGetDevCaps() to get list of MIDI output devices.
Is this function deprecated?
Thanks,

If a function is deprecated then typically compiler issues a warning. If you want to be sure then check MSDN.

I still get the same error.what i have to do is ,when i click a button,I get another dialog with the edit box.when i enter the value i have to get in the mesagebox and also for further processing.
the error is left of '->GetWindowTextA' must point to class/struct/union

What is the type of var ? You probably have to use a "." instead of a "->".
|
|
|
|
|
var->GetWindowText(szVal);//szVal is a CString variable.AfxMessageBox(szVal);
This is wrong.
If 'var' is ur control variable, then you should call like this.
var.GetWindowText(szVal);

Can you show your code and your declares?
|
|

If you want to call GetWindowText() you should add the member variable as "Control" not as value. Also after adding member variable you should call as follows.
CEdit m_Edit;
CString csTemp;
m_Edit.GetWindowText(csTemp);
Another way is add memeber variable as "value" and select appropriate type from "Variable Type" combo box. Abd Call UpdateData() for getting the data entered in edit box.
