From what I've read, they are vastly different. I've read very few positive comments about VS7's UI.

The Visual Studio IDE is great. Is it different than older IDE's Yes. If it wasn't different then it wouldn't exist right? The Class Wizard in previous VC++ IDE's was OK at best.

IMHO just because you are used to something does not mean it is better than something else. If you don't like change your in the wrong line of work.

But, that just my opinion... I could be wrong.

I was also looking for the classwizard, to no avail. However there is still a way to accomplish everything you would like from the IDE. For instance, in the properties window, you can find the messages for a control and add a function for them from the control's property page. You might already know this, but I didn't and it took me a while to figure that one out, even how to change the id of the controls!!

If it's broken, I probably did it

when i run the following code in VC++ it gives "-1" as output.Why?

main()
{
printf("%d");
}

printf("%d");

You need a value associated with the format specifier:
printf("%d", x);

x would be some object in your code to be displayed in decimal format.

MSDN:
"The printf function formats and prints a series of characters and values to the standard output stream, stdout. If arguments follow the format string, the format string must contain specifications that determine the output format for the arguments."

Your format string is "%d" but no arguments follows that format string. so basically the printf function (knowing that it is a variable arguments function using a __cdecl calling convention) will take from the stack the parameters it needs (based on the format string "%d" you said i give you an int) and construct the string and send it as output

So the value -1 is a value the printf function is taking it from the stack.

Hope i kind of answered your question

If you want to output the string %d to the console then use "%%d", otherwise add the variable as someone has already suggested. Smile | :)

You hve to have a value for it to display it would look like this:

main()
{
printf("%d", 2);
}

I am working on a SDI project. The main window has a title in the title bar that I am trying to change. For some reason the name appears as: untitled - XXXXXX.

XXXXX represents a valid name, but I cannot get rid of "untitled."

Thanks.

In the main frame window's PreCreateWindow() method, remove the FWS_ADDTOTITLE style.

FWS_ADDTOTITLE will actually append information to the window title. You want to remove FWS_PREFIXTITLE from the window style. Here is the code I've used below:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
	cs.style = cs.style - FWS_PREFIXTITLE; // no document titles.

	if( !CFrameWnd::PreCreateWindow(cs) )
		return FALSE;
	// TODO: Modify the Window class or styles here by modifying
	//  the CREATESTRUCT cs

	return TRUE;
}

Hope that helps.

Of course. Did I indicate otherwise?

Which is why I said "...remove the FWS_ADDTOTITLE style." in my earlier post.

mellertson wrote:
cs.style = cs.style - FWS_PREFIXTITLE; // no document titles.

Which obviously will not work. You'll need to AND the style with the one's complement of FWS_PREFIXTITLE.

Dude, don't get all huffy. The code I posted does work, I'm using in my app right now.

I wasn't trying to be rude in my correction, just a polite correction.

When you override the main frames PreCreateWindow function, the value of cs.style will already include FWS_PREFIXTITLE. That's why you can subract it out like this:

cs.style = cs.style - FWS_PREFIXTITLE; // no document titles.

And it will remove the "untitled -" prefix from the application.

You said:
In the main frame window's PreCreateWindow() method, remove the FWS_ADDTOTITLE style.

You were incorrect in removing the FWS_ADDTOTITLE.

See the definitions below for more clarification.

Taken from http://msdn.microsoft.com
Frame-Window Styles
FWS_ADDTOTITLE Specifies information to append to the end of a frame window title. For example, "Microsoft Draw - Drawing in Document1". You can specify the strings displayed in the Advanced Options dialog box in AppWizard. If you need to turn this option off, override the CWnd::PreCreateWindow member function.

FWS_PREFIXTITLE Shows the document name before the application name in a frame window title. For example, "Document - WordPad". You can specify the strings displayed in the Advanced Options dialog box in AppWizard. If you need to turn this option off, override the CWnd::PreCreateWindow member function.

The initial problem was trying to get rid of the prefix "untitled".

FWS_ADDTOTITLE adds information to the end of the window title, it doesn't add a prefix.

David, I really wasn't trying to be rude, just trying to make a small correction. Take it for what it's worth.

No huffiness here!

mellertson wrote:

The only reason it works is because the window already had the FWS_PREFIXTITLE style. Had it not, your method would fail, whereas mine would not.

mellertson wrote:

I disagree (in the context of an MDI application). In order to remove "- untitled" from the frame title, the FWS_ADDTOTITLE style must be removed. Removing the FWS_PREFIXTITLE style simply changes the order of the document name and the application name in the frame's title. For an SDI application like the OP indicated, the behavior may indeed be different.

In any case, my point was how to remove the style, not what style to remove.

Set button style

Can you suggest me a way to change dynamically the button style from bitmap to text and viceversa?

I tried with

m_BUTT_25.SetButtonStyle(BS_TEXT);<br />
m_BUTT_25.RedrawWindow();

and

m_BUTT_25.SetButtonStyle(BS_BITMAP);<br />
m_BUTT_25.RedrawWindow();

but nothing seems to happen... Frown | :(

I can instead change the button caption with SetWindowText: why is this? Confused | :confused:

Thanks

Marco.

Not all styles can be changed at runtime, this might very well be an example. A common method is to destroy and recreate the button.

marcomars wrote:

Because the text is not a style.

Maybe you have to "detach" your object (text, icon, bmp) from the button first?
