My project is building under _UNICODE. But I sure that my problem still occurs as soon as I don't build under _UNICODE.

Hello, I'm getting closer to what I need guys. I've managed to find the names of the windows I want to click on but I need to know how to get the X and the Y cooridinates of the windows of the game (they are child windows) so I can have the mouse moved there so it can click on the correct part of the windows to continue the game (I'm creating a macro) Any help is welcomed

If you have the ID of the control you can do this:
CRect rect;
GetDlgItem(ID_OF_CONTROL)->GetWindowRect(&ect);
This returns the location of the window in screen coordinates. If you need them in client coordinates, you just do a call to:
ScreenToClient(&rect);

I guess I don't understand what you mean by Id of the control. This is what I've got. With a window Spy proggie I've picked up I've found out the main window for the program is this :
The Class name is RealmGame3, that never changes. The Child windows however has class names like : Afx:400000 :1000f. So at this point I'm really confused as to what I'm supposed to do. heh. any help would be great.
Thanks Dimar

Hi:
I make a programme based on IWebBrowser2(or chtmlview).In MSDN, it says that: this function "Retrieves the handle of the Microsoft® Internet Explorer main window.".but I want to overwrite this function to let it return my main window（otherwise in my programme ,it always return NULL）.how could I do?
Thanks.

I'm writing a CAD program, which will have a lot of commands like create various types of entities, move, scale and rotate entities, knot edit, etc. And the drawing file may probably grow to a large size.
In general, there are two approaches to implement undo and redo, the first is Command Pattern, and the second is CheckPoint method.
CheckPoint method saves the WHOLE file into memory every times when there's document changing. The advantage of it is command independent, but this will be unendurable when the file grows very large.
Command pattern consumes less memory, but it requires almost every command implementing inverse operation, it will be a heavy burden. And in some cases, inverse operation is hard to do.
Is there any other method that implement undo/redo, for example, using checkpoint, but only saving the changing part of the drawing?

I am thinking the Command pattern is the way to go. If an operation is difficult to make an inverse operation the program can reload the commands from the beginning. In this method the data file will be the list of commands the user did in the GUI. Backing up is as simple as erasing a command from this list then reloading the entire list.

I am trying to set the default folder view the explorer uses for ALL USERS on a machine to details view.
I would prefer to do this programmatically, but anything would help.
Thank you for your time,

How can I register a Win32 DLL in regisret so that it can be accessible to a VB client?
|
|
|
|
|
regsvr32 dllname
this command will register the dll in the registry...
This is done for COM inproc dll. I guess you dont have to register a win32 dll to be accessed by vb client.
The dll should be in the path or in the same folder where the vb binary lies.
Besides it is same as using "user32.dll" of windows.

If I register using regsvr32 it gives error the it cannot "Find DllEntryPoint"
|
|
|
|
|
That means that its not a com dll, so no point in registring it,
I dont know how to do it in VB but i guess you will find plenty of examples how to use win32 dll in vb.

For VB6 there's an add-in which lets you generate definitions and stuff to allow direct use of the Win32 API when appropriate.
Essentially, you have a code module within which the DLL exported entry points are declared, along with their parameters. You can also alias the entry points, to give them friendly names, then use them like regular VB sub/functions.

Write the dll as a com component and do what the other person said.

Hi,
im currently working on a MDI project. it concerns displaying waveforms, with data read from a text file.
iv added the zoom in and zoom out feature in the UI, but im having trouble in having the display updated within the same window.once a user clicks on the zoom in/out button, he needs to click on the "new" icon to have the zoomed picture displayed.im aware that the OnFileNew() is within the CWinApp class, therefore i cant call it from my CView class.
can someone please tell me how to call the OnFileNew() function from within the CView class? or am i suppose to do it another way?
thanks alot..

If I'm understanding the problem correctly (I'm not an MFC guy), it sounds like calling the OnFileNew() function would just be a work around anyway. I think you should probably be storing, inside your CView subclass, the necessary data to reconstruct the display when zooming. If that overhead is too large (i.e. too memory intensive), then I'd recommend creating some sort of object to encapsulate access to the file, with the necessary functions to read the data as many times as necessary. Then you should be able to share that object between the CWinApp object and the CView object.

Dear sir,
im still unclear about the solution uv put forth.
do u mean that im suppose to derive an object from the CWinApp, so that i can access the OnFileNew() with it? how do i do that?
can u please show me a code sample please?
secondly, would it be too much if u can explain to me how to close the present window when the new window is loaded?
on the second thought...is there any other method where i can have the new zoomed display updated from within the same window, without having to close and open a new window instead?
many thanx

I can't give you a code sample. I'm not experienced with MFC.
I'm certain that you can update the display from within the same window, but again, I don't use MFC, so I can't give you details. Sorry, but the best I can do is recommend that you read some documentation and figure it out yourself.
It just sounds like your program is doing things in a very round-about manner. There's got to be a simpler way.

It is probably not SDI but rather MDI.
