Hi I got a project which involves interprocess communication. I uses pipes because it's only happend in one machine. It seems everything should be perfect. However, When I try to connect The Client and The Server. I always have an Error number 231 ( All pipe instances are busy) when I try to create file in client side. Client --> Create File, Write File Server --> Create Named Pipes, Read File here is some of the code in my programs

m_hPipeHandle = INVALID_HANDLE_VALUE;
m_hPipeHandle = CreateFile(ISOCOMSPIPE,GENERIC_WRITE,FILE_SHARE_WRITE,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

if(m_hPipeHandle == INVALID_HANDLE_VALUE)
{
int iRet = GetLastError();
printf("Error number %d",iRet);
}

closeHandle(m_hPipeHandle);

Is there anything wrong in the attributes/ missing attributes when I want to create the file ? Thx

I changed the way my program works. instead, waiting for period of time, then shutdown I keep it loop until keyboard event occurs or user press close and I discovered that there were some memory leaks in my program. I fixed the memory leak, change the program flow and done Anyway, thanks for your help Regards, Arif Liminto

thanks I've fixed that one

Hi, I am still a newbie in MFC I 've got a problem with my console application program I use one thread in there , which is I use CWinThread and it terminates when time is equal to timeout but I need to handle if the user want to terminate immediately in the console application so the way I did is I create this function

BOOL WINAPI ConsoleHandler(DWORD CEVENT)
{
switch(CEVENT)
{
case CTRL_CLOSE_EVENT://if user shutdown immediatelly
myClass.CleanUpThread();

	break;
}
return TRUE;

}

so when the user want to immediatelly, it will go to that function and clean up the thread however, everytime, I test and debug, I always windows ballon said that "windows cannot end this program, it may need more time to complete an operation" How to disable that ballon? so i dont want user to see that one, and the program will wait until the thread is cleared. Thanks so much,

yeah I've stepped through the code i also try to add some debug code

bool bResult = false;

if(myDataAdapter.Fill(myDataSet) > 0)
{
bResult = true;
}

and I monitor the value of bResult, the result is true. if I use GridView,it works perfectly, so I dont think there is a mistake in transferring from database to dataset, I suspect the problem when transfering from DataSet to FormView, which i use the same mechanism when i use GridView set the data source -> FormView.DataSource = DataSet; bind the data -> FormView.DataBind(); is there anything that I need to add more? Thanks so much

Hi, I am still a newbie in ASP.net, sorry if I am asking stupid message. I am trying to develop some website using asp.net 2.0 and I currently have some difficulity to use one of the ToolBox called FormView for displaying the data from database I want to transfer from microsoft access to FormView here is the code

OleDbConnection myConnection = new OleDbConnection(myConnectionString);
myConnection.Open();

OleDbCommand myCommand = new OleDbCommand();
myCommand.Conn = myConnection;
myCommand.CommandText = "SELECT * FROM [USER] WHERE UserName = @UserName";
myCommand.Parameters.AddWithValue("@UserName",sUserName);

OleDbDataAdapter myAdapter = new OleDbDataAdapter(myCommand);

myDataAdapter.Fill(myDataSet);

FORM_View_Users.DataSource = myDataSet;
FORM_View_Users.DataBind();

myConnection.Close();

I think I did with the correct way because when I tried to run the website, I did not get any exception error, However, I couldn't see the formview, it just blank . Is there any attribute that I need to fill in so I can see the data in the Form_View ? thanks

Hi, I am still a newbie in ASP.net development, I try to learn about nested master page, and I got this problem Cannot find ContentPlaceHolder 'ContentPlaceHolderUser' in the master page '/OnlinePrayer/MasterPage/AdminUser.master' I have done some research in internet, but until now, I have not got the right solutions. basically, in my website, there are 2 master page : AdminUser.master and User.master and AdminUser is child of User, In User.Master , I've got this following code

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="User.master.cs" Inherits="MasterPage_User" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>UserPage</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:contentplaceholder id="ContentPlaceHolderUser" runat="server">
</asp:contentplaceholder>
</div>
</form>
</body>
</html>

and in AdminUser.master, i've got this code

<%@ Master Language="C#" MasterPageFile="~/MasterPage/User.master" AutoEventWireup="true" CodeFile="AdminUser.master.cs" Inherits="MasterPage_AdminUser" %>

<asp:Content ID= "SubContent1" contentplaceholderid="ContentPlaceHolderUser" runat="server">
</asp:Content>

I thought that I had define ContentPlaceHolderUser in User.Master, but I dunno why I still got this error? in Admin.Master I would be grateful if you could give me feedbacks about my problems, thanks
