Are you wanting to set the window text of the 3rd dialog dynamically? In that case, you could pass it as a parameter to the constructor of the 3rd dialog class and have a string member variable initialized with that value and then call SetWindowText() in InitDialog(). That sounds viable?

Call SetWindowText() from within its OnInitDialog() method.

Hi,
I have MDI application, which loads office files (word,excel,ppt) but while loading excel doc I was unable to user "Freez Panes" functionality. This is bcoz when we open any document thru MDI application, this MDI application will have its own "Window" menu with default sub menus ("New Window", "Cascade","Tile", "Arrage Icons") but it does not have "Freez Panes". I would like to know is there any way to implement such functionality.
I have tried to add another menu called "Freez Panes" but need to add functionality for it. Pls help.

Thanks

How to load bitmpas dynamically?

When i directly loaded into resources(IDB_BITMPA) my exe is occupying more size. Instead of that how can i load at run time from bitmap images (res\image.bmp)

If you're using Win32 API, you may use LoadImage [^], for instance

HANDLE hMyBmp = LoadImage(NULL, _T("res\\image.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

On the other hand, if you're using MFC/ATL, have a look at CImage class documentation [^], the Load method looks promising.

What kind of a program is that? What does it do? Perhaps you don't need a windowed application then?

However, to answer your query, you may use ShowWindow(SW_HIDE);

You never answered any of my questions. Why can't you send your app to tray instead, if at all it has an UI? If it doesn't need an UI, then why a dialog based app? Confused | :confused:

Again, to answer your query, with windows start-up, you could invoke your app with a command line parameter and check for it in the InitInstance() and then use ShowWindow(SW_HIDE);

I understand your problem as this - how to identify whether the application is started during windows startup.

I think you've managed to start your application on startup, by adding under - HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Well, in that case just pass a commandline argument /startup or something like that. So that when started, by checking the command line arguments, you can identify whether its started during windows startup or manually and can hide your main window accordingly.

Jijo.

Well, let me ask you how do you manage to start the application during windows startup? via registry or by creating shortcut in startup directory?

in both cases, you could pass the command line together with exe path. for instance,

c:\hello\hello.exe /startup

Well, in your application, you have to parse and check for the command line string - /startup. You could use the function GetCommandLine() to read the command line string. This link[^] will be useful.

[Edit]
Check out this link[^] too for parsing command line.

Jijo.

okay, then you have to specify the your exe path in registry, like this

c:\Hello\Hello.exe /Startup

then, /Startup switch will be sent to your application as command line. Well, I've already explained about how to read the command line from your application. Smile | :)

Commandline arguments are the parameters that we pass to application while starting it up. You don't need to write any specific code for sending commandline argument to application.

Well, did you modify your registry startup entry as i suggested? Just do it and call GetCommandLine() from you application. And you'll be able to see the "/startup" in debugger.

Don't hesitate to ask, if you have more doubts about it.

Jijo.
