OK, problem partially solved.
I added RegisterShellFileTypes after my AddDocTemplate(), but the assocation is shown with a small sized icon, not the standard size icon you would expect to see if you were viewing a file list with "details" selected from Windows Explorer.
How can I affect the associated icon?
TIA

Check the icon file that you are using. It does not/should not contain just one image. It should contain multiple versions with different color depths and sizes. (You may have to look around in your icon editor to see how to move between these versions.)
You may be missing a needed size/color depth version, so Windows is trying to make due with something else. For some more information see here[^] and here[^].Please do not read this signature.

Well, at lest the WAV file format is documented [^].

Hello,
I have to add some blank spaces at the end of line.
How to add blank spaces at end of line while file writing?
Which file class i have to use CFile or CStdioFile?
for e.g.
suppose i have to write string
"Hello, how are you "
I have to add 10 space after the word "you".Abhijit

|
|
|
|
CStdioFile::WriteString("Hello how are you ");
10 spaces after 'you'; I don't understand what your difficulty is with this. Please try and clarify what you are trying to do.txtspeak is the realm of 9 year old children, not developers. Christian Graus

If you're going to read and write on a line by line basis, then use CStdioFile. It exists for this purpose.
And what's your problem writing 10 spaces? Write it like you would write normal characters.

Hi There,
You could do this in one or more ways.
One way is to us the \t escape routine. Which works a little like this:
Somefile << "Some text to write to file\t";
That would add one tab space after the word file. So you could add a couple of \t escapes.
or use formatting functions instead. one example thereof is:
printf ("Width trick: %*d \n", 5, 10);
You would just have to figure out which is best for you.
Though printf() is routed to the console by default, you could use it or its counterparts to route to a file
object instead.
Hope this helps

Hi All,
I am using VS2005. In my application i am finding a window and enumerating its childs. Now i need to send messages to each one. I have tried to send WM_COMMAND, WM_CLOSE, etc..I have a doubt regarding sending keystroke messages to a window.
How to Send the Combination Key "Ctrl + P" to a window.
Please give your valuable suggestions...
Regards,
Spk

you have to something like this
WM_KEYDOWN -Send CTRL
WM_KEYDOWN - SEND P
WM_KEYUP-SEND P
WM_KEYUP- Send Ctrl "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow

I have referred to chapter 20 of "teach yourself vc++ + in 21 days by sams " for socket programming using CAsyncSocket class.
I need to understand & implement if the physical connectivity is available or not if "send" command is send. Below is the code snippet.
CString m_strMessage="S";
m_strMessage=m_strMessage+'\x00A';
int iLen = m_strMessage.GetLength();
// Send the message
int iSent = m_sConnectSocket.Send(LPCTSTR(m_strMessage), iLen);
if (iSent == SOCKET_ERROR)
{
AfxMessageBox("Socket Error");
}
else
{
// Sync the variables with the controls
}
It was observed that iSent does not give "SOCKET ERROR" even though Ethernet connection is not available. I need to indicate the user that there is some socket error problem.
I have tried adding below lines of code before send command. But still it does not return correct error code & indicate that the socket connection is not available.
int conn_stat,last_error;
conn_stat= m_sConnectSocket.Connect(m_strName,m_iPort);
last_error= CAsyncSocket::GetLastError();
The last_error remains 0 even if Ethernet cable is removed. Shall I use a timer feature & keep checking if the connection is available or not. If yes, could you help me in achieving this?

If I'm right you will not get an error because the message was delivered to your networkcard. So create a timer (see Settimer()/Killtimer()) and reset it everytime something is coming in from the server. When the timeout comes close your socket gracefully.
Note: It could be handy to look for the asynchrone versions for sockets. In basis you list all sockets events you are interrested in to a window (see Windows API WSAAsyncSelect()) and it will send you window-messages when that event is actual. With this you will get a window-message stating for example your socket is ready to send...
Good luck

A TCP socket will not return an error immediately if a network connection is going down. This is by design, if there is a short network outage the connection can recover... on the other side it takes a couple of minutes until an interrupted connection is reported back to the socket (and will be closed with an error).
You can do two things to detect an interrupted connection, such as a removed Ethernet cable:
1) Implement a reasonable fast heartbeat. If peer A wants to know about the status/availability of peer B, it either has to receive a "message" from B in regular intervals (and therfor knows that peer B is alive) -or- when there is no regular traffic to piggyback the heartbeat then one of the peers has to initiate (additional) heartbeats in reasonable intervals. For example an IRC server uses regular ping/pong messages every few minutes to find out about the connection status of its chat clients.
2) Use the IP Helper API[^] to check if your local network interfaces are down.
Hope it helps!

Hello,
I have tried with CRegistry project from code-project and CVORegistry project from http://www.voscorp.com/products/developer/winmobile/vostring/index.htm[^]. But I am not able to read HKEY_CLASSES_ROOT\CLSID\{D27CDB6E-AE6D-11cf-96B8-444553540000}
I can open till HKEY_CLASSES_ROOT\CLSID but inside it I am not able to open ...
Other Keys and values are working fine I have tried reading those. But I don't know why keys that are in GUID format are not getting open example like {D27CDB6E-AE6D-11cf-96B8-444553540000}
I am sure that key exist I have checked in registry.
Any suggestion.

The following code works successfully -
::RegOpenKeyEx(HKEY_CLASSES_ROOT, _T("CLSID\\{00020000-0000-0000-C000-000000000046}"), 0, KEY_READ, &hKey);
It will not work if I give KEY_ALL_ACCESS instead of KEY_READ.
The return value says "Access Denied" (5).
For KEY_ALL_ACCESS to work I have to run my program as administrator.
Check the return value of RegOpenKeyEx to determine the cause of failure.

A Big thanks to you ...
Actually I was getting ErrorCode 3 (Path not found) but I did not checked error-code. Thanks for reminding that.
The problem was with my pc bit version. I am on 64-bit version. So when I searched registry for key
{D27CDB6E-AE6D-11cf-96B8-444553540000}, I found it "Wow6432Node\CLSID\{D27CDB6E-AE6D-11cf-96B8-444553540000}" path.
So I was fetching it as
RegOpenKeyEx(HKEY_CLASSES_ROOT, _T("Wow6432Node\\CLSID\\{D27CDB6E-AE6D-11cf-96B8-444553540000}"), 0, KEY_READ, &m_hkey);
and it was giving path error. While the path is right, I have checked in registry.
but when I removed "Wow6432Node", all worked fine. I think registry/api was redirecting my call.
I was also confused with "(Default)" but I googled out. Now going to test in different pcs and users if all works fine everywhere.
Thanks
Rahul

Hi
I'm going to make the viewer like "edraw office viewer component" with c++builder2010.
I'd tried to use WordApplication,WordDocument,OleCotainer, but failed.
Do not you have seen the open project or open component like this?
Do you know about "OpenOffice.org"?
Ask for advice...

Hai,
I have an application(exe) which makes a report based on some values in an ini file.This ini file is not a static one, we changes the value every 14 days(or over a fixed period of time).If we give our client this exe with the ini file along with it, any time we make changes we hav 2 send the new .ini file to him.But we dont want that. i tried to put the .ini file in the server and given an url for the file & this exe should read from that file.But it nt wrking.Can anybody please Suggest me a solution for this.
Thanks

Why don't you make your architecture relly client/server. With the client (your application) asking the server for the data?

One way is as Carlo has suggested.
Alternatively
Your client should download the ini file from URL specified when it starts and use it.
I hope it helps.Regards,
Sandip.
