Search for the word "service" in the articles here at CP.

And/or look at these articles:

I am trying to obtain a file path from handle in Windows NT driver. The PFILE_OBJECT->FileName contains only the path such as "\directory\file.ext" but not the device name or drive letter. How do i obtain the device name (drive letter) for the file?

I think there could be a way throught the PFILE_OBJECT->DeviceObject, but can't dig out from the DDK documentation how to get the name of this device.

Thanx

How to scroll text ?

Hi
I want a MFC application in which I want to scroll some text. Also sometime text might be long and sometimes it might be short. Also Font size of text might need to be as big as 200. So is there a way to do it ?

I tried using CBannerStatic example given in this site, but problem occurs when i make my text size big. It stops scrolling and consumes 100% CPU making other application work very very slow.

So I want to make it myself and text shold scroll smothly without any flickering.....is there a way to do this ?

Thankx a lot in advance

I have used this one AIM-Style Scrolling Banner Control
[^]and found it to work fairly well.

Either way, why note dissect the code locate the problem and let the author know. Most authors seem to enjoy others helping them with their projects.

trik is in this

void CScrolDlg::OnBUTTONstartStop() <br />
{<br />
	// TODO: Add your control notification handler code here<br />
	m_Scroltextje = m_InputTextVariabel;<br />
	<br />
<br />
	m_scrollengt = m_Scroltextje.GetLength();<br />
	m_scrollengt = m_scrollengt -1 ; //er 1 van af halen<br />
//	m_Scroltextje.Delete(m_scrollengt,1);// this is for if the scrol text choud end<br />
	m_Scroltextje.Delete(0,m_scrollengt+1);// this is for if the begin  of the scrol text<br />
					//   0=this is the position in text<br />
					//   scrolltext+1 =  amoud of charackters wat must be deleted<br />
	UpdateData(FALSE);<br />
	<br />
}

Of course there is, but it can become complicated.

Only print the part of the text that needs to be seen and nothing else. That is you need to know: which is the first visible character and what its x coordinate is, as well as which visible character is last.

Check out GetTextExtent() amongst others.

Oh, one last note: The Windows text output functions states that they are limited to 8192 characters. That's not exactly true, the number of characters depend on the size of the font; in otherwords, the total number of pixels in the string length is limited to 32767.

Can anyone pls tell how to configure "Network Logon Security" while creating a profile using MAPI.
I need to create the profile without showing the profile creation dialog box (exchange server dialog box).

i used the following code to create a profile.
i could successfully create a profile, but the "Logon Network Security" option is set to "NT Password Authetication" by default.
i want to change it to "None" programmatically using MAPI.
how do i do that ??

please help.
Thank You.

if (FAILED(hRes = MAPIInitialize(NULL))) {
AfxMessageBox("Could not Initialize MAPI");
return FALSE;
}

if (FAILED(hRes = MAPIAdminProfiles(0,&lpProfAdmin))) {
AfxMessageBox("Could not Create Profile. Contact Admin");
return FALSE;
}

if (FAILED(hRes = lpProfAdmin->CreateProfile(szProfile,szPassword,NULL,
MAPI_DEFAULT_SERVICES))) {
AfxMessageBox("Could not Create Profile. Contact Admin");
}

Crystal Report 10 add parameter

There is some good spirit that knows the correct way to pass the parameters to a report
I explain myself better....

I have created the following objects:
.
.
.
.

try {

// Creazione istanza
m_pApplication.CreateInstance("CrystalRuntime.Application");

// Apro il report
m_pReport = m_pApplication->OpenReport((LPCTSTR)m_sFileRpt);

// Lista parametri report
IParameterFieldDefinitionsPtr pParamFieldDefinitions =
m_pReport->GetParameterFields();
LONG lCount = pParamFieldDefinitions->GetCount();

// Ciclo sui parametri del report
for(LONG lItem = 1; lItem <= lCount; lItem++) {

// Puntatore oggetto parametro
IParameterFieldDefinitionPtr pParamFieldDefinition = pParamFieldDefinitions->GetItem(lItem);
.
.
.
.

I am successful to read the parameters set up in the report but not to save them...any example in the net is in VB but not in VC++..

DateTime param or Other correctly...

Thanks in advance..

The working group for unicode ISO 10646 has been around since 1991, so even the libraries that come with VC6.0 should support it.

What do you mean by normal chinese?

Do you mean Taditional Chinese (probably)?

Do you mean Simplified Chinese?

I forget, which one is Big-5?
