Ok here's my problem:
I've created a setup project that installs my application on a computer, and creates a shortcut to this application on the Desktop.
This application uses a configuration file that is supposed to be in the same directory as the application (save to "./configfile.cfg"). This file is updated every time the application is closed.
Also, in my application, the user can save a different type of file by himself, using a SaveFileDialog.
The problem is:
When the user saves a file during a session with my application (say, in My Documents), the configuration file ends up in the same directory (ie. My Documents).
BUT when the user doesn't save any file during the session, the configuration file ends up at the right place.
Does anyone know what's going on???

Could you post the code for saving with SaveFileDialog and saving of your configuration file.

Ok here's the code for my configuration file:
FileStream file = new FileStream("./config.cfg", FileMode.OpenOrCreate, FileAccess.Write);<br />
BinaryFormatter formatter = new BinaryFormatter();<br />
formatter.Serialize(file, network);<br />
file.Close();
And here's my code for saving the user file with a SaveFileDialog:
saveFile.Filter = "Events Tables files (*.etf)|*.etf|All files (*.*)|*.*" ;<br />
saveFile.FilterIndex = 1;<br />
DialogResult result = saveFile.ShowDialog();<br />
if(result == DialogResult.Cancel)<br />
return;<br />
FileStream file = new FileStream(saveFile.FileName, FileMode.OpenOrCreate, FileAccess.Write);<br />
BinaryFormatter formatter = new BinaryFormatter();<br />
formatter.Serialize(file, events);
file.Close();

Don't use the relative path string to open the filestream to your config file. Better
string path = Application.StartupPath + Path.DirectorySeparatorChar + "config.cfg";
FileStream file = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);

I have a situation where I am reading a MS SQL database table containing user
names and passwords in a C# program.
After applying Server Pack 3 to SQL to this database I can no longer get a user
to successfully logon.
The program is in C# and the particular line of code is:-
dr["Passwrd"] = AE.GetBytes(password);
How can I resolve this.
Regards,
Alf

The first thing I would suggest is to check and see what AE.GetBytes(password) is returning before you assign the value.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitdebugging="true">
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

Stefan.

Make sure the assembly bison1.dll is in the your executable's folder. U have a direct reference to it in your code (shell object, line 182). If u dont, then u must be using third party assemblies and the references are contained within those. In that case you will need to get a copy of the bison1.dll file.

Thanks again for your help. I needed quite some time to get my solution working, one of the things was assigning one outputpath for all projects in their properties.

Stefan.

As the Subject asks, how can I store data in a SQL database which I take frome a DataGrid, I'm specially curios about the combined SQL C#-vars Command String.
I'm new in C# and I already get data from SQL to the DataGrid, I nowhere found an article about. Even not in Cookbooks.
PS: Is it possible to set every DataGrids Column Width to an own value?
tnx for Help

Is there a namespace in C# for grabbing a computer's information? with tools like MSINFO32, I can see that the objects do exist to retrieve that info, i just cant find it.
If c# doesnt have it, it should be possible to create a dll in c++ or vb.net to retrieve it, then grab that in C#, correct?
Yes, I am the highly suggestable type.

Hi
I am writing a socket server for plain old TCP connections. I am just having real trouble trying to determine whether or not a remote connection (from eg. a telnet client) is in fact still active. The only good way it seems to do it is to send data to the connection and to see if it throws a socket exception. There must be a better way to determine that the telnet client has closed his session.
Does anyone know how I can do this?

That's the right way. From MSDN, on Socket.Connected property documentation, this is explained:
"Because the Connected property only reflects the state of the connection as of the most recent operation, to determine whether a connected socket is still connected, you should attempt to send or receive a message. Once the message send fails, this property will no longer return true. Note that this behavior is by design. You cannot reliably test the state of the connection because, in the time between the test and a send/receive, the connection could have been lost. Your code should assume the socket is connected, and gracefully handle failed transmissions."
Yes, even I am blogging now!

I need a way to get the values of fields from an array of classes, passed as an object to a method.
myClass[] mc = new myClass[10];
myMethod(mc);
where myMethod is defined as follows.
public void myMethod(object obj) {
Type t = obj.GetType();
if (t.IsArray) {
}
else {
foreach (FieldInfo fi in t.GetFields()) {
Type fieldType = fi.FieldType;
}
}
}
Thank you for any help.

Use
System.Reflection;
MemberInfo[] mi = t[i].GetType().GetMembers();
MemberInfo type gives informtion about members
|
|
|
|
|
Thank you, but I have tried that already. It does not compile, returning the error
"cannot apply indexing [] to an expression of type 'System.Type'
(or something like that) for "t[i]".

Hi, I've developped a small tool that add appointments in outlook 2003 calendar. My problem is that I can't detect appointment conflicts...
here is my code :
connect to outlook
create a new appointment :
Outlook.AppointmentItem appointment = (Outlook.AppointmentItem)applicationObject.CreateItem Outlook.OlItemType.olAppointmentItem);
fill-in appointment fields (start / end time, subject, alldayevent=true, reminderset=false, busystatus=outofoffice)
then i do a 'save' on the appointment, and then look at the conflicts list of my appointment:
appointment.Save();
Outlook.Conflicts itemConflicts = appointment.Conflicts;
if (itemConflicts.Count > 0)
this check is never raised, even if my appointment is in conflict with another appointment the same day.
What should I do to have those conflicts detected as soon as I save my appointment (or even before I save it ??)
Thanks for your help

Hi
I developed a C# interface, that will be called by the VC++ code and it is working fine.
For deployment I am registering the C# dll in the client machne using the regasm.exe tool.
Now I am planing to develop my own MSI application using Installshield,
any idea how to do this?,
One more point I understand is it is not required to call regsvr32.exe to rigister a COM component if I am doing the deployment through MSI application.
