hi!
I migrated an existing vc++ 6.0 application using activeX objects to VC++.Net (7.0) environment.
Initially I had problems with the ActiveX objects since they were not being supported in the recent version,the old code had the activex objects being accessed using the GetDlgItem() function,moreover this made sense since the function in which the objects were used were static.
I however created objects and accessed them using the cDialog ptr.
Things compiled well and the program works,but when I close the application I get a lot of memory leaks which is not acceptable... it says something like oleinit.cpp(i guess it might be something to do with the ActiveX objects).Secondly the application is being run in debug mode,I have to expilicity close the debug mode even after the close the window??
Is there anyway to close the activeX objects or delete them so that the memory used by them is to be freed explicitly..
Why is this happening?? any comments ..please help
thanks

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"; 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';

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

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

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...

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

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.

OK. Thanks for the info guys. I'll just stop wondering what a nonzero return means, unless I have another reason to suspect a problem.
Thanks Again,

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.

Only by drawing all the controls and windows yourself.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

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.

You have to write Custom Manifest file for that!
here is link to achieve same

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.
