you can use the function SetRange32 to increase the range of your spin control.

kindly deselect "No thousands" check box in the spin control properties dialog.

CSpinButtonCtrl *pCtrl = (CSpinButtonCtrl *)GetDlgItem(IDC_SPIN);

pCtrl->SetRange32(lower limit,upper limit);

hi,

i have created the extension class ,but i am using this extension dll in an ocx control. though i export the whole class using AFX_EXT_CLASS and use it in my ocx, my ocx is not able to initialize in ActiveX test container. when i also export my functions ina .DEF file it initialize. I dont understant when it is already exported using AFX_EXT_CLASS why should i again export in a .DEF file.

implicit loading of the DLL has a problem, as extension
dll cannot be used in ocx as far as i know. so i have to
load it dynamically.

thanx for the help

Change button browse order

Hi guys,

I have a dialog with serveral CButtons. I notice I can go through (highlight) the button by pressing UP/DOWN/LEFT/RIGHT arrow key, however, it is not in the order I want. I am wondering if there is a quick way to change the "browse order" without manually doing it using WM_KEYDOWN. Has it got something to do with Resource.h ?

Also, in the dialog based application, Does hitting the Return(Enter) key always call the OnOK()? In my app (where there are child dialogs), sometimes it calls OnOK() of the parent dialog but sometimes it would launch OnBnClicked() of default button on the parent window. Is there a way I can insure to alawys call the OnOK()?

Please help,
Thanks alot.

you can choose tab order from the layou menu, to order the flow of control.

the button which you wish to get pressed on pressing enter key, set the button as default in its properties.

First, tell us what they are.
Second, tell us what version (VC6, VC7, VC2003) you are using.
Then we might be able to help you. In this forum, there is a lot of knowledge assembled.

In <functional>? Probably not.
This might be where the compiler gives up, but the error is in your code. DoO you have an example of your code that gives an error?

How do I change the value at certain positions in
a TCHAR*?

If I do..
TCHAR* pStr = _T("Bo Hunter");
pStr[pos] = _T('O');
it breaks with access violation.

If I do..
TCHAR szStr[MAX_SIZE] = {0};
lstrcpy(szStr, _T("Bo Hunter"));
szStr[pos] = _T('O');
it works.

Thank You

pStr[pos] = _T('O');

shouldnt it be
*pStr[pos] = _T('O');
or
*(pStr + pos) = _T('O');

I tried all of that before.

// Illegal indirection
*pStr[pos] = _T('O');

// Access violation writing location 0x0049924d.
*(pStr + pos) = _T('O');

I am within the bounds of the string for sure.
pStr starts at 0x0049924c

I thought for sure that
*(pStr + pos) = 'O';
was wright.

Thank You

Now pStr holds the adress of the constant string somwhere in the code. This memory is not writable. You need to copy the string to a writable location, either on the stack (as you did in your second example), or on the heap (by allocating memory using new).

GetPrinter return incorrect info about SharedPrinter.

hi!
i'm trying to get the number of jobs that in queue of a shared printer.
i used the code that shows in the MSDN:

<br />
BOOL GetJobs(HANDLE hPrinter,        /* Handle to the printer. */ JOB_INFO_2 **ppJobInfo, /* Pointer to be filled.  */<br />
             int *pcJobs,            /* Count of jobs filled.  */ DWORD *pStatus)         /* Print Queue status.    */<br />
{   <br />
	DWORD               cByteNeeded,<br />
                        nReturned,<br />
                        cByteUsed;<br />
<br />
    JOB_INFO_2          *pJobStorage = NULL;<br />
    PRINTER_INFO_2       *pPrinterInfo = NULL;   /* Get the buffer size needed. */ <br />
<br />
	if (!GetPrinter(hPrinter, 2, NULL, 0, &cByteNeeded))<br />
	{<br />
		if (GetLastError() != ERROR_INSUFFICIENT_BUFFER)<br />
			return FALSE;<br />
	}       <br />
	pPrinterInfo = (PRINTER_INFO_2 *)malloc(cByteNeeded);<br />
	if (!(pPrinterInfo))<br />
		/* Failure to allocate memory. */ <br />
		return FALSE;       /* Get the printer information. */ <br />
	if  (!GetPrinter(hPrinter,2,(LPBYTE)pPrinterInfo,cByte<br />
Needed,&cByteUsed))<br />
	{<br />
        /* Failure to access the printer. */ <br />
        free(pPrinterInfo);<br />
        pPrinterInfo = NULL;<br />
        return FALSE;<br />
    }       /* Get job storage space. */<br />
	TRACE("NUM OF PRINT JOBS: %d\n",pPrinterInfo->cJobs);<br />
	if (!EnumJobs(hPrinter,0,pPrinterInfo->cJobs,2,NULL,0,(LPDWORD)&cByteNeeded,(LPDWORD)&nReturned))<br />
	{<br />
		if (GetLastError() != ERROR_INSUFFICIENT_BUFFER)<br />
		{<br />
			free(pPrinterInfo);<br />
			pPrinterInfo = NULL;<br />
			return FALSE;<br />
		}<br />
	}<br />
	pJobStorage = (JOB_INFO_2 *)malloc(cByteNeeded);<br />
	if (!pJobStorage)<br />
	{<br />
		/* Failure to allocate Job storage space. */ <br />
		free(pPrinterInfo);<br />
		pPrinterInfo = NULL;<br />
		return FALSE;<br />
	}<br />
	ZeroMemory(pJobStorage, cByteNeeded);       /* Get the list of jobs. */ <br />
	if (!EnumJobs(hPrinter,0,pPrinterInfo->cJobs,2,(LPBYTE)pJobStorage,cByteNeeded,(LPDWORD)&cByteUsed,(LPDWORD)&nReturned))<br />
	{<br />
		free(pPrinterInfo);<br />
		free(pJobStorage);<br />
		pJobStorage = NULL;<br />
		pPrinterInfo = NULL;<br />
		return FALSE;<br />
	}       /*<br />
        *  Return the information.<br />
        */ <br />
    *pcJobs = nReturned;<br />
    *pStatus = pPrinterInfo->Status;<br />
    *ppJobInfo = pJobStorage;<br />
    free(pPrinterInfo);<br />
	return TRUE;   <br />
}<br />

This code returns the number of jobs, and a pointer to JOB_INFO_2 struct.
i'm using this code to clear the queue list of the printer:

<br />
JOB_INFO_2* jobs;<br />
int noj;<br />
DWORD status;<br />
BOOL err=false;<br />
if (err=GetJobs(hPrinter, &jobs, &noj, &status))<br />
{<br />
	for (int j=0;j<(int)noj;j++)<br />
	{<br />
		SetJob(hPrinter, jobs[j].JobId, 0, NULL, JOB_CONTROL_DELETE);<br />
	}<br />
	free(jobs);<br />
}<br />

but if this printer is a shared printer (from another computer), some times i get num of jobs = 0, and some times the correct one.
most of the times, if i'm F11ing (stepping into) the GetJobs function it works, but if i just do F10 it returns num of jobs = 0. i tried to move the little yellow arrow (in VC++ .net) to the command and do it again, and after 2-3 times it return the correct num of jobs...

Is it a RPC error?

What can i do?!
thanks,

Another method is to iterate throught each item in the list and check wheather it is selected or not.
