I guess I've been using CString for too long because for the life of me I can't remember how to assign a value to a character array (not through initialization). I thought I could do something like

szTerm = " \r\n"; // szTerm is declared as char szTerm[4]

but that just gives me errors. Am I completely off with this and do I have to use strcpy and it's associated functions...? Thanks.

char szTerm[4] = {0};
szTerm[0] = ' ';
szTerm[1] = '\r';
szTerm[2] = '\n';

You can't assign to a char array, you need to assign to the individual characters as in Maxwell's post, or use _tcscpy()

（1）char szTerm[4]={'a','b','c'};
(2) char szTerm[4]="abc";

you can also use strcpy(szterm, " \r\n"); from <string.h>

VS.NET and "picture controls"

I'm doing some dialogs in Visual Stupido.NET, and I can't seem to find a way to may a simple etched frame. I don't want divider lines, and I don't want captioned group boxes. I want what I used to be able to do in Visual C++ 6.0's resource editor.

Does anyone know if what I want to do is even possible?

So far, I'm not impressed with this new crap from MS...

In the properties for the picture control, set the color to Etched.

Activex question

Hi everybody.

I'm writing an Activex, that it interact with the serial com, sending commands.
Thats ok.
But I have two questions:

First, I like to know how to adjust the size of the control when someone put it in a form, (in VB or in a Dialog in C++). 'Cause in OnDraw() I draw a BMP, but I want to fix it to an especific size and disabled sizing. I want to fix the size for the desing time, because the control is not visible at runtime.
Then, how can I show a tip, (a short description), in the Property window, (in the bottom of the window) when a property is selected. Where I should write that description in the Activex project??.

Thank you.

Demian.

can't you handle the WM_SIZE message and just set it back to whatever your size is?

If it's broken, I probably did it

Exit Code (0x2) from Dialog Based Apps

Justin Cooke13-May-04 8:39

13-May-04 8:39

Greetings,

I have been using dialog based MFC apps for a while and just noticed that, at least in my applications, the exit codes aren't always 0 (even when things seem to be working correctly otherwise.)

If I run any of my dialog apps from the debugger in VS 6.0, and I then close the app with either System->Close, Alt-F4, or the 'X', I see the following messages:

The thread 0xBF4 has exited with code 2 (0x2).<br />
The program 'C:\Documents and Settings\justin.cooke\My Documents\MyProjects\randomNumGen\Debug\randomNumGen.exe' has exited with code 2 (0x2).

If I instead close it with the OK or Cancel buttons, the exit codes are 0, as expected.

What's going on? Does the 2 code just indicate how the app was closed? I was always under the impression that a code other than 0 indicated an error. I tried to find a list of what these codes mean in MSDN and online, but had no luck.

Thanks,
Justin

That's a hold-over from the DOS days. Read the docs for CDialog::EndDialog().

OK. I've already taken a look at that info. I understand any int can be returned. How do I know what 2 means? In this case, I'm guessing it just means OnClose was called, but how do I know for sure? Is there a list of return codes somewhere? When I'm running with the debugger and I see nonzero codes, how can I tell if they indicate errors?

Thanks for your help,
Justin

Look in winuser.h, about 3/4 of the way down.

Thread and process exit codes have no inherent meaning, the code is just a DWORD that can be used for any purpose. As the other poster said, not every app will exit with 0; and if you see a nonzero exit code it doesn't imply an error happened.

Windows XP look and feel on other applications

Is there a way we can give Windows XP look and feel to applications running under other operating systems beside Windows XP?

I belive if you have a manifest file and the version of Windows has the newer common controls file you can give it the XP look.

I suppose you mean Windows OS's. Take a look at WindowBlinds[^], maybe it fits what you need.

If you want XP look and feel for programs you have the source code, you already are on the right place.

Toolbar bug?

Hello,
I've used code similar to the one written by the author of http://www.codeproject.com/docking/toolbarcombo.asp, I place a combobox at a toolbar, everything works great untill I set the style of the toolbar to flat, and then, when the buttons are set to be 32x32 I see the separator under my combobox. Any suggestions or ideas on how to get rid of that separator?

Thanks in Advance,
D.
