Not meaning to sound cocky but doesn't this mean you can do it? If the third party company has done it, or do you mean it can't be done in C# / .NET?

Noone's figured out how they do it yet, but I suspect they rewrote the API's Outlook is using, and left out the Security junk. That could be done in any language, but it's a lot of work just to get around that warning.

I want to to get to know how to develop a simple parser to analyse simple c# code .
e.g:Chech a for loop in a sample code to verify that it is syntacticaly :-correct.

hey
i am developing a web application using asp.net, but coding in C#.

You take the values and run the query through an SQLCommand Object, that's the simplest solution...

i coded a bit.. but now sql database i showing an error if i keep the field "Username" as a primary key.
firstly the data is entered in a very ad-hoc fashion.. there is a row empty at the top...data entered in between two rows which are already filled with data..
and if i delete some data,then i get the error as
"Another user has modified the contents of the table,the database row ur modifying no longer exists in the database....... violation of PRIMARY KEY constraint...."
THE CODE:-
try
{
SqlConnection conn = new SqlConnection("server=(local);" +
"database=path;" +
"connection timeout=3;" +
"Trusted_Connection=yes;" +
"Integrated Security=true;" +
"user id=sa;" +
"password=");
conn.Open();
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandText = "Insert into login(Username,Password) values('"+uname.Text+"','"+pass.Text+"')" ;
SqlDataReader dread = cmd.ExecuteReader();
if (dread.Read())
{
failed.Text = "Could not add the user";
}
else
{
Response.Redirect("success.aspx");
}
conn.Close();
}
catch(Exception kp)
{
failed.Text=kp.Message;
}
}

Hey all,
As mentioned in one of my earlier posts, I'm currently coding a class which inherits from System.Windows.Forms.Button.
My goal is to create a ShapedButton class, with a built in functionality to shape the button according to a drawing in a Bitmap object.
I do not intend to write a new UserControl, encapsulating a button.
My intension is to directly inherit the Button class.
However, the problem is that it would be immpossible to design my ShapedButton in design view, and I would have to manually write the code to InitializeComponent().
How can I use my ShapedButton in the designer?
Do I have to create a UserControl?
If that's the case, then how can I inherit Button? There's no multi-inheritance, and I would have to inherit UserControl first...
Thanks in advance,
Shy.

Do NOT write any code in InitialiseComponent, the IDE recreates that code.

You can't, as you say, once you inherit from UserControl, that's it, excepting for interfaces.

What can I do than in order to gain the ability to design the button in the designer?

It's not exactly what you wan't, but it might help you out a little bit because it enables you to use at least some designer abilities. To outwit the designer do the following:
Let's say you have a class MyButton derived from Button . To place an instance, first place a usual Button Control on your form by using the designer (let's name it myButton1). In your code replace the designer generated code private System.Windows.Forms.Button myButton1; with private MyButton myButton1; and in InitializeComponent() use your own class, which results in replacing this.myButton1 = new System.Windows.Forms.Button(); with this.myButton1 = new MyButton(); . This should make the designer switch to your own data type permanently and your own properties and events should also be listed by the designer. Hope this helps.

Well... I didn't try your suggestion, so I can't tell you if it works...
I have found my truly beautyful solution (in my opinion at least ).
I have discovered that after inheriting System.Windows.Forms.Button, the icon of my file in the solution explorer, changed itself to a component's icon.
So I started reading about components, and finally I've discovered my solution:
A component is defined as a class which implements the IComponent interface, or inherits from a class which directly/indirectly implements the IComponent interface.
So I checked the heirarchy of the Button class, and there it was!
Button indirectly implements the IComponent interface.
So I kept on reading, and found that with some simple attributes added to your class, your class can have what is called a "Design-Time Support"![^]
Thank you all again.
I hope this info would help others to achieve similar goals.

Hi
I was just searching for that solution - great !!!
My problem was that I could not open the designer after I derived a class from TreeView (I got HTML errors in the designer) .
Now I added the following property to the derived class:
[Designer(typeof(SimpleControl.Design.SimpleDesigner))]
then I reopend the form in designer - in voala the garphic was displayed !
Thanks a lot for that hint!

I have an assembly that is strongly named and is added to the GAC. All works well. however, if I obfuscate the assmebly using Dotfuscator I get the following error:
Failure adding assembly to the cache: Strong name signature could not be verified. Was the assembly built delay-signed?
Any ideas on how to fix this?
|

You need to obfuscate it before adding the strong name. The strong name includes a cryptographic hash of the contents of the DLL, which is verified on adding to the GAC, and obfuscating it (obviously) changes the contents. Use sn.exe with the -R switch to strong-name-sign a DLL. You may need to specify /delaysign+ to the compiler for sn.exe to work.
I found I had to do this when rebasing a Primary Interop Assembly generated with tlbimp , since tlbimp does not allow the base address to be specified.

i finsih work in my first project and i need to make setup package that include project files and database and sql server engine and i need to setup engine and database during project setup on client computer

I will "answer you quickly":
Into the setup project add as a prerequisite sql server (msde or express)and a custom setup action that mounts the database files or execs some scripts to gen the database.
Is this quick enough?
protected internal static readonly ... and I wish the list could continue ...

in general every window got is's own button in statusbar on desktop - my question is - how to check if the form is general on-top (or is active) and make it's statusbar button "flashing" like internet communicator window when new message is coming...??

If a forms property ShowInTaskBar is set to true then yes, most applications have a window in the taskbar. You can make the taskbar window for your application 'flash' by using the API commands FlashWindow and FlashWindowEx. You can learn more about these commands by googling the application API Guide and API Viewer. I also have code for this in VC#, but at the moment I am not at the right computer.
