Hi!

Either you use .NET 2.0, where a template system is supported, or you use public void storeValue(object o) and sacrifice type-safety.

Nevertheless, you can query the real type of the object passed to your function using the typeof or is operators.

.net 2 has support for ssl streams (SslStream class)
in 1.1 you have to use 3rd party products.

If you need more info, look at http://lab.msdn.microsoft.com/productfeedback/viewfeedback.aspx?feedbackid=d772e3b3-2697-43b9-a1bd-d05ffd74f685[^]

You can use the zip libraries through J#. I did this a while back, but I completely forget the details. I don't remember whether I wrote that part in J# and exposed it to C#, or whether it was directly accessible from C#. Now I'm being too lazy to go look it up for you, but this should get you going in the right direction... You can always post back more questions if you need more help.

What type of project in c# .net

Guys,

I need to developed a program in C# that runs every midnight and this program will be executed by our server. This will read data from SQL server and send notification to specific person. The question is which Type of project will I be using "Console Application", "Windows application", "Windows Server"????

I tried to use the Console Application but when I tried to execute the sqldataadapter statement it gives me an error <code>"Additional Information: Request for the permission of type System.data.sqlclient.sqlclientpermission,System.Data, Version=1.0.5000 ...</code> but when I run the same sqldataadapeter in WEb project it works perfect.

Please I need the answer ASAP... thanks.

How are you connecting in your code, use a SQL server account rather than trusted account as it will be lost once the system service runs the code.
The console app is the righ one to use.

Yes, I am glad I am on the right track. This is how I connect.

SqlConnection objconn = new SqlConnection("server=server1;database=Personnel;uid=person;pwd=person123;");<br />
objconn.Open();<br />
SqlDataAdapter objadap = new SqlDataAdapter(sSelect,objconn);<br />
objadap.Fill(DSEmployee);<br />
objconn.Close();

Does it mean the I will replace the current connection ID with the connection ID/password that I am using in connecting to the sql server?

Thanks for your help.

Yes,

you need a connection string like this

SERVER=SQLserver;uid=user;password=pass;DATABASE=Sales

Also you have to go into SQL server enterprise manager and create a SQL Server user (one not based on a domain account) with enough rights on the required database to insert change data etc..

Dear ones,
I have a specified width, and a long string. I want to know with complete accuracy how much of the string fits in that width for a give font. I have used MeasureString,GenericTypographics, TextRenderingHint etc. But i am not satisfied with the results. Give me any clue,function,API etc that could give the exact string that fits in that specified width.

Windows Event Log

hi,

I create in my application a new custom system log and send all my logs to it. In some cases, the log gets corrupted, and the solution I have is to either clear the log or remove it and create a new one instead.

Is there a way to actually find which entries are invalid and remove them and keep the rest of the entries available for me? Or is it possible to go through the entries, and copy the valid ones to a new log file?

Thanks

I think you better find out what you are doing to get these invalid messages. D'Oh! | :doh:

I know what leads to corrupt my log. sometimes a hard shutdown makes my logs corrupt, a system crash can give me that. I'm not looking for a way to prevent it, I'm looking for a way to repair it without clearing or deleting the log.

How are you using the EventLog? Are your sure you dispose of it after every write, or do u keep an instance static? If the latter, thats likely the cause of the problem. Use the static methods to write as they will properly close the eventlog after writing to it.

And I found on the net an actual way of reparing the corrupted one and/or export the entries to HTML or Excel sheet.

c# Word Addin - sinking events

Hi all,

My question is about how to intercept Office event in a C# add-in. I want to intercept file printing, saving, copying etc. I know that I can intercept events in VBA by supplying the rights macros, eg for file print,

Sub FilePrint()
MsgBox "I am printing " + ActiveDocument.Name
ActiveDocument.PrintOut
End Sub

The Application.Class in Word does not seem to have a FilePrint event
So my question is how do I achieve this functionality in a C# add-in ?

Thanks in advance

static Method And Thread Safety

Hi guys, I am facing a problem regarding static methods, what happens when we call a static method (accessing only local variables),

public static void HelpMePlease()
{
int a=0;

a++;
Console.WriteLine("A must be 1 " + " a :" + a.ToString());

a++;
Console.WriteLine("A must be 2 " + " a :" + a.ToString());

a++;
Console.WriteLine("A must be 3 " + " a :" + a.ToString());

a++;
Console.WriteLine("A must be 4 " + " a :" + a.ToString());
}

Lets suppose, I call this method from 50 threads simultaneously.
will All methods keep single copy of a. or each one will have its own copy.
Please explain it comprehensively, compiler internals etc.
Thanks in advance

You already wrote the code, what does it do? On the latter part, local variables are created and placed on the stack, so each call will have its own locals.

yeah all methods are maintaining their own copies.
all i wanted to know is what copiler does when a method is called ??
is there any diffrence between behaviour of compiler when you call a static method ??

When you call a static method, there is no reference to the object, as there is no object. Other than that, there is no difference.

Calling a static method does not use the address of an object:

Console.WriteLine("test");
=
ldstr "test"
call void [mscorlib]System.Console::WriteLine(string)

Calling a non-static method uses the address of the object:

num.ToString("d4");
=
ldloca.s num
ldstr "d4"
call instance string int32::ToString()
