C / C++ / MFC

I have to face an assertion when i try to delete some component (textbox, button,and these methods) frequently. After delete these componet and methods, i can't compile successful although it's ok before. It's very difficult for me to modify a project. Can you recommend me the best way to modify these component in Visual C++.
Thanks so much.

I have just try some more. When i try to delete every component which have member variable, the exception: "Access violation" occur. I can delete other components successfully.

hai Thuan,

if you are in MFC, better delete the methods and variables in the ClassWizard.
I think no need to modify the program. And then delte the corresponding component in the dialog box.

Helping others satisfies you...

You just delete all messege map & member variable associated with that component in the class wizard.

Hello Thuan
If you are working with Dialog based application, open header file whose name is like CMyDlg(in your case, there is your project's name instead of My. Got it?) and delete all functions and variables associated with that control and then compile. I hope it will solve your problem.
Good luck.

Maybe you forget to delete DDX and DDV code?

I have the same experience because of this reason.

Can you tell me about DDX and DDV more details.
I have just try the Aqueel's suggestion. I deleted all member variable and function of the Component in .h file, compile and run, everything is OK. But when i delete the component in Resource View Window, i met an Assertion and when i chose Retry to debug, the code have to debug is:
if (hWndCtrl == NULL)
{
TRACE1("Error: no data exchange control with ID 0x%04X.\n", nIDC);
ASSERT(FALSE); -->Point at this row
AfxThrowNotSupportedException();
}
Can i solve this problem.
Thanks you so much.

In function DoDataExchange maybe contain some DDX or DDV code to the control you deleted in resource view. such as DDX_Control(pDX, IDC_BUTTON1, m_btn);

I think it should be the reason according to your last reply.

Hi all,

First of all, I'm very comfortable with command-line compilation
with GCC, and VS.net IDE environment, but I'm trying to figure
out how to use VS.net compiler tools in command-line environment.

<br />
In command prompt, I typed: <br />
<br />
cl main.c <br />
<br />
and I got this error: <br />
<br />
/out:main.exe<br />
main.obj<br />
LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'<br />
<br />

Have I done anything wrong? Did I forget to set any PATH? What am I
supposed to do to compile a simple main.c?

Thanks

ok you compile main.c, but you don't tell it neither the name of the target exe, nor the libs to link, nor anything else...

if you want to loose time with the commande-line compilation, do this Big Grin | :-D

When using CEdit (VC++ 6) with multiline.
How to input New Line ?
like following:

CString strMsg;
strMsg.Format("\tHello\n\tWorld");
SetDlgItemText(DLG_ITEM_ID, strMsg);

Expect result is:
"
Hello
World
"

But the CEdit output as following:

"
Hello World
"

try add ES_MULTILINE to edit style
you can modify edit style by resource editor ,or code.
Code sample:

CEdit *pEdit = GetDlgItem(DLG_ITEM_ID);<br />
pEdit->ModifyStyle(0,ES_MULTILINE);<br />
<br />
CString strMsg;<br />
strMsg.Format("\tHello\n\tWorld");<br />
SetDlgItemText(DLG_ITEM_ID, strMsg);<br />

HOW WHAT8-Mar-06 14:52

HOW WHAT

8-Mar-06 14:52

edit control -> mouse right click -> properties -> styles -> Multiline

strMsg.Format("\tHello\n\tWorld"); -> strMsg.Format("\tHello\r\n\tWorld");

\n New line
\r Carriage return
