I have an CComboBoxExt derived from CCOmboBox .. but I have an small problem , perhaps you can help me :
CComboBoxExt m_Combo;
void CTestComboView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
GetParentFrame()->RecalcLayout();
ResizeParentToFit();
m_Combo.AddString("One");
m_Combo.AddString("Two");
m_Combo.AddString("Three");
}
and when I type 'O' in combobox , it select me automatically 'One' item from the list ... well , I try this one :
void CComboBoxExt::OnEditupdate()
{
CString sText;
GetWindowText(sText);
DWORD dwCurSel = GetEditSel();
WORD dStart = LOWORD(dwCurSel);
WORD dEnd = HIWORD(dwCurSel);
if(dStart == 0 && dEnd == sText.GetLength())
SetEditSel(sText.GetLength(),sText.GetLength());
}
but have no effect ....

I forget to say something :
I use this , may me this cause weird behaviour ?
void CComboBoxExt::OnEditchange()
{
CString sText;
GetWindowText(sText);
if(sText.IsEmpty())ShowDropDown(FALSE);
else ShowDropDown();
}

Which is? 
You've shown code, but have failed to explain what is supposed to happen vs. what is actually happening.

Hello friend, I think a lot of people in this board have ever been used "Print to file" option in Printer Dialog.
That it can save our printing job to file and then print it out later.
I want to create a program that can read that file.
And the program also can revise the printer setting and page set up before the real printing.
Please advise me some concept or article of this task.
Thank you

I assume you are talking about the .xps file.
There is a COM API provided by Microsoft for working with this file format. See the documentation on MSDN[^]
Grab the latest version of the Windows SDK[^], which you will need to comiple your project, but also has some great little samples under the folder C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\xps (alternativley you can download just the samples from http://code.msdn.microsoft.com/xps[^]). The documentation for these samples can be found on MSDN[^].

hello, anyone have an idea of a code in MFC to shut down with time the pc ? in Vs 2008 ?
|
|
|
|
|
|
the function ExitWindowsEx[^] can be used to shut down the computer.
To do it after a specific period you could use something like Sleep(1000); (wait 1 second) or a WM_TIMER event in a GUI application.
To do it at a specific time you need to figure out how long to wait. Use either GetSystemTime[^] or GetSystemTimeAsFileTime[^] to get the current time, then calculate how long you need to wait. After that you can used 1 of the previously mentioned ways of delaying.

First and foremost, PLEASE remove most of the code and keep only the minimum necessary code.
I admit I did not read all of the code...
Maybe each book can have a std::vector of author ? after that is done, re-thing your class design and the UI design to that that into consideration.
for example (pseudo-codish):
typedef std::pair< std::string firstName, std::string lastName> Author;
class Book
{
std::vector<Author> m_Autors;
}
Watched code never compiles.

Hello,
I am VC++/MFC developer. I wanted to start Bluetooth socket programming. Can you suggest any good book or article specific to Bluetooth programming.
Regards
|
|
|
|
|
|
Actually I went through all these pages..but I am not getting what I exactly want. I have completed my application using these pages, I myself not willing to use that.
I know I need to use Winsock2. But still something is not working properly.
Regards
|
|
|
|
|
Get a copy of the latest Windows SDK[^] and take a look at the bluetooth example in C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\netds\winsock\bluetooth
|
|
|
|
|
OK. I will try and let you know. Thanks
|
|
|
|

You could check out the source of my Bluetooth remote control written in C++/MFC. It uses modified MFC CAsyncSocket to listen to Bluetooth connections.

Hello,
I am VC++/MFC developer. First of all I wanted to know is there any way in windows to block website. Suppose I wanted to block Facebook.com.
Secondly, I wanted to create one application that will block listed website. Suppose I have list of website with me viz; Google.com, orkut.com, Microsoft.com. I want to write application which can block these website.
Thanks in advance.

There are couple of things i can think off.
1. put sites url to a ini file for example then use API for working with inifiles (write / read profilestring)
2. get a list from ini file and resolve each site's ip
3. put then these ips into C:\Windows\System32\drivers\etc\hosts file and redirect to localhost for example
4. write a driver to disable write permissions on that file (you need to hook ntwritefile and some more)
5. that still will not block apps, which use custom resolver (anyways, most of apps use gethostbyname).
Or, maybe, detect network threads, then inject own thread into them and block access to a site on that level.
011011010110000101100011011010000110100101101110
0110010101110011

Hi,
I have added following line @ hosts file
66.220.146.11 www.facebook.com
but still facebook is running.

It should be:
127.0.0.1 www.facebook.com

"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons
"Man who follows car will be exhausted." - Confucius
|
|
|
|
|
The simple solution is having a program that modifies the hosts file, and gives the blocked domains an invalid IP address.
The normal solution in a corporate network is to setup a filter on the gateway to the Internet.

Can you please give me steps how should I filter gateway?
|
|
|
|

The gateway is a seperate computer working as router, that includes its own software for configuring DNS lookups and firewall.
Usually the router provides a web-browser interface that allows one to configure it. Not something you would do through a MFC application.
