Re: error C2601: 'CreateArrayOfRandomNumbers' : local function definitions are illegal

I presume you've just included a snippit of the whole file there. This error is often caused by mismatched braces further up the file where you have one more open brace than you have close braces.

For example :

void MyFunction1()
{
    // Do something


void MyFunction2() // Note closing brace of MyFunction1() is missing
{
    // Do something else
}

Remove the semicolon at the end of this statement:

if( NULL == pArray );

There is a misplaced semicolon in this statement (or you got bite by HTML formatting):

for( int i=0; i);

int *CreateArrayOfRandomNumbers(int nSize)
{
    int *pArray = new int[nSize];
    
    if( NULL == pArray )
        return NULL; // memory allocation error

    for (int i = 0; i < nSize; i++)
        pArray[i] = rand();

    return pArray;
}

ZModem protocol

Hi guys,

I'm implementing zmodem class which is downloaded from another site, programmer's heaven. I'm implementing that class in VB for my project work.

I'm not expert in VC++, but I'm able to convert the VC++ DLL into VC++ OCX and using that OCX in VB project. I made OCX cox, I need to use the same in PowerBuilder too.

I exposed 3 methods InitCOMM(), SendFiles(), ReceiveFiles() to use in VB.
The handle in VC++ classes for writing and reading COM port is defined as void *, and exposed them as long int.

I established the connection between 2 computers using MSCOMM control in VB, and passed the MsComm1.COMMID to the InitCOMM() method to initialize the zmodem class. Now, it gives automation error when I use Send/Receive functions, .. the vc++ WriteFile() always fails to write to COM port in I/O overlapped mode.

Can any one help me, how to get rid of this or any other solution for ZModem implementation.

thanks in advance

how to open file faster?

in my app, i need open files very fast.
the function CreateFile() is very slow, i.e. for a file of 10K bytes, the function needs around 10-50 ms (related to PC) to open it.

do u have idea to open files faster?

thx

Well on Win32, CreateFile is about as low level as you are going to get. The speed of the open operation should not be dependant upon the size of the file, but the speed of reading the file will surely be dependant upon the file size. If you are really talking about the speed of reading files, I would suggest looking into memory mapped files. They are very very fast to read. Take a look at MapViewOfFile in the MSDN.

If you really are only concerned with the speed of the CreateFile (and not reading the file), then sorry I cannot be of any help.

Just curious. Why do you need to open the file faster? 10 ms isn't that bad,
depending on what you are doing.(Opening for read or read/write?)

Change the default title of an application?

Hello All,
I have a SDI application in MFC.

By default, all the forms/windows (including the main form/window) and all the messageboxs will use this application's name as the title(caption).

However, I want to change the default titles/captions for this application to another name. How can I do it easily?
I know I can use the SetWindowText (or some similar functions) to set each window's caption one by one. But any better way to do it? How to change the "default" caption to what I want?

Thanks a lot and have a nice day. Smile | :)

You can't use SetWindowText() with the main or child frames. Use CMainFrame::OnUpdateFrameTitle() etc.

Modify the string table in the resource file.

Change IDR_MAINFRAME to the new name.

Hi everybody!

I have an MFC problem this week at work:

I write an application dynamically linked to MFC. This application is dynamically linked to one of my DLL, which is an MFC extension DLL, so it links MFC too.

When I build the DLL : no problem as in debug mode as in release mode.
But for the application : in debug mode, no problem, but runtime crash when I use the DLL fonctions (ASSERT fault), and in release mode, the program compile well but I have linkage error for each MFC symbol in my program, because the linker says that the MFC-symbols was already defined, in my DLL.

I try so tips to avoid this message, but I fail Frown | :(

Does somebody know how to get ride of this problem? Thanks by advance!

PS : sorry for my english! Frown | :(

Signed Twofy.

Challenge: Scanning local machine for shared folders

Hey,

I used to program in school but haven't in some time.

What I'm trying to do is to write a batch file that would probably be used when a user logs onto the domain and does the following:

1) scans the pc for shared folders
2) turns the shares off

thats it.

I never programmed for something that do somthing like that. I wrote software like a menu based ordering system that Subway could use for making sandwhich's

any help is appreciated

CListCtrl: Delete all columns?

Dominik Reichl15-May-03 7:36

Dominik Reichl

15-May-03 7:36

Hello,

I have to dynamically create and remove columns in my project.

Creating them is relatively easy but what is the correct way to delete all columns?

I currently have this code:

while(1)
{
	if(m_clMainView.DeleteColumn(0) == FALSE) break;
}

But is this a valid method to delete all columns? It never failed but perhaps an OS doesn't assign column number 1 to column number 0 when column number 0 gets deleted?

How would you do it?

Confused | :confused:

-Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Re: CListCtrl: Delete all columns?

David Crow15-May-03 7:44

David Crow

15-May-03 7:44

That'll work. You'll always have a column 0, unless there are no columns.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
