The switch statement has nothing to do with MFC. It is a C construct.

I met a problem when writing a mfc regular dll. I want to export a funcion which create an object extending from CWnd. To my surprise, there occurs an error when calling the CWnd::createWindow()--return NULL as the window handle , however,it works very well if I directly add the class source in my project.
what should I do? Can anyone help me? Thanks very much!

You have two choices that work fairly well.
1. Call a function to display the window and all opeations are contained entirely within the DLL - this works well for dialogs, mostly.
2. Create the DLL as an MFC Extension DLL - the application loading the DLL should be an MFC application. Then you can export the entire class and use it within the application just fine.
Anything else is mixing the models MFC was designed for and will result in strange problems now and in the future.

Although less reliable, you could try using GetWindow() in a loop.

I believe they have an SDK. Have you looked into that?

Hello everyone.
I have a dialog attached in a frame, the propery of dialog is "child", in the dialog there are some edit boxs, comboboxs and buttons. When these controls in dialog got focus, I want to catch the active event. I tried to add WM_ACTIVE to dialog, but it can not be called. How to know when the dialog is activated?
Thanks.

How can I connect to a SQL/MSDE database. I figured I couldn't use CDaoDatabase since it's not an Access database that I want to connect to. Is this the connection I should use?
strConnect = _T("Provider=sqloledb;Data Source=MyServerName;"
"Initial Catalog=MyDatabaseName;"
"User ID=myUsername;Password=myPassword;");
Now how do I use this string to connect and query my database?
Thanks!

Have you considered using ADO?
|
|
|
|
|
Yes but isn't using ADO in C++ very complex? My program isn't COM-based so it may be a little difficult to implement. Are there other alternatives to using ADO?
|
|
|
|
|
I'm using ADO in my app and to be honest I don't even know what COM is. I didn't find it very difficult, I'm not aware of easier alternatives (but I'm no expert). This article was very helpful to me:
http://www.codeproject.com/database/simpleado.asp[^]
If you have any more questions I'd be glad to help but we should probably move this over to the SQL/ADO/ADO.NET message board.

Thanks Wilsonian! I'll try it out and if I'm still having problems I'll post it in the SQL/ADO/ADO.NET board. Thanks again!

Im looking for a method of get the effective size of a dinamic array created with the new statement, because the sizeof instruction only gives me the size of the pointer or the size of the first element of the array, maybe that i don't know how use that, but i really want to know the size of an array without having the number of elements of the array, (if it's posibble) the same as UBound property in VB6.
PS: excuse if this text is a little confuse, i'm from argentina and my english is basic.
Thanks

|
|
Either the class that you use to create your dynamic array has member functions to check the size, or it doesn't. What class are you using to create your dynamic array?
