hi
i need to add Ip Address as the value for the registry.
Example,like this
Registry Name = public
Registry Type = REG_SZ
Registry Data = 10.20.40.80
but using below code am able to add only one value as "1"
#include "stdafx.h"
#include <windows.h>
#include <stdio.h>
int _tmain(int argc, _TCHAR* argv[])
{
unsigned char szStr[20]="12.45.67.89";
HKEY hKey;
// opening a subkey, then creating and setting a value
if (RegOpenKeyEx(HKEY_LOCAL_MACHINE, TEXT
("SYSTEM\\CurrentControlSet\\Services\\SNMP\\Parameters\\s1"), 0,
KEY_ALL_ACCESS, &hKey)!=ERROR_SUCCESS)
printf("\nError opening the desired subkey (doesn't exist?).\n");
else
{
if (RegSetValueEx(hKey, TEXT("public"), NULL, REG_SZ, szStr, sizeof
(szStr)) ==ERROR_SUCCESS)
printf("\nThe value of the key was set successfully.\n");
else
printf("\nError setting the value of the key.\n");
}
RegCloseKey(hKey);
return 0;
}
Output am getting in the registry data field is " 9"
could you please help me regarding the above issue.

You are being very good about using TEXT macros, and TCHAR... while leads me to think you are using UNICODE.
In which case, your address needs to be stored as a TCHAR array also.
Ie:
TCHAR szStr [] = _T("12.45.67.89");
...
if (RegSetValueEx(hKey, TEXT("public"), NULL, REG_SZ, (BYTE *)szStr, sizof (TCHAR) * lstrlen (szStr)) ==ERROR_SUCCESS)
...
I'm assuming your access of hKey is succeeding?
Can you delete the "public" value using regedit, and see it getting re-created?

<code>TCHAR</code> szStr[20]= <code>_T(</code>"12.45.67.89"<code>)</code>;
HKEY hKey;
if (RegOpenKeyEx(HKEY_LOCAL_MACHINE,
_T("SYSTEM\\CurrentControlSet\\Services\\SNMP\\Parameters\\s1"),
0, KEY_ALL_ACCESS, &hKey) != ERROR_SUCCESS)
{
printf("\nError opening the desired subkey (doesn't exist?).\n");
}
else
{
if (RegSetValueEx(hKey, _T("public"), NULL, REG_SZ, <code>(const BYTE *)</code>szStr, <code>(_tcslen(szStr)+1)*sizeof(TCHAR)</code>) == ERROR_SUCCESS)
printf("\nThe value of the key was set successfully.\n");
else
printf("\nError setting the value of the key.\n");
<code>RegCloseKey(hKey);</code>

Hi,
I am using a CListCtrl in a dialog box. The column headings are initialized in OnInitDialog() function.
Now what i want a certain butoon on Dialog box the Column header should change dynamically.
Please Tell me how to do this.
Thanks in Advance.

Well, work it through...
You have a CListCtrl, and you want to do something with the header.
CHeaderCtrl *pHeader = m_pMyListCtrl->GetHeaderCtrl ();
Now you can manipulate the header.
Looking at the docs for CHeaderCtrl, you have a "setitem" function.
It takes an item number, and a HD_ITEM struct. Burrowing deeper, you just have to set the mask of the struct to say "my text field is valid", and the text field to your new string.
HD_ITEM hdItem = {0};
TCHAR buf [128];
lstrcpy (buf, _T("Hello"));
hdItem.mask = HDI_TEXT;
hdItem.pszTest = buf;
pHeader->SetItem (n, &hdItem);
That's all nicely untested, but should work a treat.
Good luck,
Iain.

Hello, I have used the following code
HD_ITEM hdItem = {0};
TCHAR buf [128];
int n=GetSelectedVisitorIndex();
CString IPAddress=-T("122.56.78.99)"
CString str=_T("Visitor Details:")+IPAddress;
_tcscpy(buf, str );
hdItem.mask = HDI_TEXT;
hdItem.pszTest = buf; // can almost certainly cast from a constant string.
pHeader->SetItem (n, &hdItem);
but it is giving error:
Error 15 error C2039: 'pszTest' : is not a member of '_HD_ITEMW' c:\Documents and Settings\Shy\Desktop\IPAddress\SourceCodes17-09-08\Source Code 06Dec2007\GetFootDlg.cpp 82
Please tell me whats the error

Look at the documentation for HD_ITEM, and read about each member variable of the struct. You should spot my (cough, cough) deliberate mistake.

HOW are you setting the font for the property sheet? It should simply take the font built into the dialog resource you are giving it, so if you're overriding that, then timing will matter a lot.

Helo,
I have two file types (i.e. .res and .ems). The extension '.res' files are in c:\AAS\ResultFiles\ folder and the extension '.ems' files are in c:\AAS\EmissionFiles\ folder. By defaul CFileDialog Opens the '.res' directory. when user selects the file type I want to change the directory according to the file type.
Can any body give an idea to do this using MFC.It should work in Windowx XP OS.
Thank you.

You can use the CFileDialog::m_ofn.lpstrInitialDir data member and set it to the desired directory.

Have you tried assigning a value to lpfnHook and see what messages that hook function receives when you interact with the dialog (specifically the "Files of type" combobox)?

Go buy VS, simple as that.
You can't have VS express and MFC. Go and spend some bucks & learn how to research while you're at it.

Oki enhzflep,
Once i will purchase the programme, i will be able to compile all those programmes including MFC Hederas and libraries?
If Yes, please share the link where i could purchase that from and any estimated prise.
I am ready to spend bucks, but main thig is ignorance with me ..
Please share with me how to purchase and where purchase from . i am brand new to this Forum and as well as into programming as well ..

Yup. paid-for VS comes with MFC and will let you compile the examples that use the SAPI.
Also, if you are a student at a recognised (by Microsoft) educational institution or have an International Student Card you can download a copy (for free) of Visual Studio Pro from Microsoft under their Dreamspark program.
You can get Info on VS here:
http://msdn.microsoft.com/en-us/vs2008/products/cc263903.aspx[^]
Make sure you check the available features before purchasing a copy. as an example, if you want to do development for mobile devices then you are unable to use Visual Studio Standard. etc, etc.
seriously dude, www.google.com - try it, it's fantastic.
Ah whatever...

Does anyone know how to get the level of pressure to use the touchpad with C / C + +?
I could not find any function of the API for this, use only one with C #.

Hi,
How can I have a HANDLE to my own running process? I want to raise its priority class.
|
|
|
|
|
Ehhh, will ::GetCurrentProcess() do?
Ehh, again after modification... 
No, probably not since you want to call ::SetPriorityClass() with a real handle. Use ::OpenProcess()[^] with PROCESS_SET_INFORMATION access right.
Actually I was right from the start even though I pulled it from the memory cache in my head... 
Have a look at the sample for ::SetPriorityClass() here[^], it uses ::GetCurrentProcess() to get the process handle.

CdrTools is a collection of CD/DVD authoring tools. Its native language is C
and it compiles in Unix. I would like to know if anybody had converted the source code of cdrtools to VC++ or .Net and compiled in Visual Studio?
I am writing an application in MFC for CD/DVD burning, in which i want to use the cdrtools source..
