Thanks Tom,

Actually I am moving away from any MFC. I only use MC++ extensions and C# for UI (I use Inside C# as a reference)

Even that I think I am going to buy your book when it comes out, if is just as good as your Inside C# I am going to enjoy reading it!

Thanks
Al

Thank you very much for the support. Have you seen the second edition yet?

Definitely the MFC book is very strong. While there will be a lot of beginner level material (no way a pub will let anyone write just an advanced MFC book for some reason), it also has tons of great material not found in any other MFC book. I think you'll get a lot out of it.

Dynamically creating variable

Ludwig Stuyck16-May-02 2:44

Maybe a strange question...

Normally you know what variables you are using in your application, and what types they are.

But suppose we have to create a variabele depending on some input.

if (input == somevalue)
int i = new int();
else
string s = new string();

This won't work, because it's not possible to create a variabele in an if statement.

Anyone an idea?

Closing one application and opening another....

Hello Friends,

Before opening my main application I want to ask for password.
For which I've created one login form. After successful login my main appliocation should get open.

Now my problem is if I want to open LoginForm first, I've to supply its object in
Application.run(loginForm);
After user entering of password and my code checking of that password I want to open my main application
depending on the condition . I want to close LogonForm at this point wheather user successfully logged in or not.
For which I hope I have to call ite close method as
loginForm.close();
But if I close this form, my next main form will not get open, as LoginForm was open with Application.Run().

I dont want to make LoginForm invisible.I want to completly destroy it and then open my Main form.

Is anybody knows any way of solving this problem.

Thanks in advance.

Create your LoginForm object in the Load_event (Idon't know what it's named) and call the show method (ShowDialog) and when the Load_event method returns your LoginForm object is destroyed!

Did I understand you right!?

Hi Rickard,

Thanks for prompt reply.

Actually, I'm making instance of Login Form in Main() class after performing certain checks.So, roughly...
public static void Main()
{
if(oneCheck)
{
if(anotherCheck)
{
LoginForm loginForm = new LoginForm();
Application.Run(loginForm);
}
else
{
//Some Code
}
}
else
{
//Some Code
}
Now in that LoginForm in the click event of OK button I'll check wheather
password is correct or not.
If password is correct My Main MDI form should open and if password is wrong one message box should open stating Password is wrong.

So in click event of OK button, LoginForm should be destroyed and either my main MDI application or message box should get open.

I hope now it should be preety clear now.

Thank you very much.

You could also check if password is correcxt in the LoginForm's buttonX_click event.
If wrong do nothing than or show a message box that tells you that it's wrong password and if it is correct password then exit dialog and TADA.... I don't know any other way so that much I can help you!

But I would do like this.

How do I authenticate a user account, given the user name, password and domain(if any), using C#? Basically I am trying to avoid duplication of the user database just for this purpose..

There is a classes that you may look at System.Net.NetworkCredential, System.Net.AuthenticationManager. But it works in conjunction with webrequests. See if it might be possible to use it

Otherwise you may need to use LogonUser API.

Running Page_Load Event

Hi All,

I am having an annoying problem that hopefully you can explain to me.
I have some code in my Page_Load event that load previous data into all the textboxes on a form.

I then enter my new data and submit, but for some reason it is clearing all the data in my form before submitting, the only reason that I can come up with is that it is loading the Page_Load event which is populating the form with blanks from my database?

Does this make any sense and can I fix this?

Thanks,
Gavin

That solves it..

Thanks,

Is there a decent reason on why it is running the Load_Page after I push submit and before the actual submit?

BackgroundImage + Centering...

It's easy to set a background image...

BackgroundImage = ((Bitmap)(resources.GetObject("$this.BackgroundImage")));

But I don't want it tiled. I'd rather have it centered in the middle of the form.

Any thoughts?

Thanks!!

You can draw it yourself through the Paint or PaintBackground event.

protected override OnPaint(PaintEventArgs e)
{
  base.OnPaint(e);
  int x, y;
 
  x = (ClientSize.Width - backgroundImage.Width) / 2;
  y = (ClientSize.Height - backgroundImage.Height) / 2;
 
  e.Graphics.DrawImageUnscaled(backgroundImage, x, y);
}

Where backgroundImage is an Image containing the image you want to draw in the background. You shouldn't also set the BackgroundImage property of the form because it will still tile the image in the background AND draw this one centered in the client area.

Thanks James.

Your method certainly works and perfectly fits the bill, but was trying to think of a very .NETish way of doing it. (Trying to convert from MFC to .NET)

I came up with the idea of putting a PictureBox on the form, then set the image and the propertiesDock=fill and SizeMode=CenterImage and it worked perfectly.

SetWindowsHookEx

14-May-02 23:41

I'm trying to use SetWindowsHookEx in C# so that I can get APPCOMMAND and KEYBOARD events from any window (not just my thread).
I created a DLL and put SetWindowsHookEx there, and then I'm using DllImport so that I can install hook in C# code.
As I receive events, I send a message to C# code through PostMessage.

The problem is that, even though I'm running SetWindowsHookEx globally, I just get events if my app window is focused. And if I use PostMessage, app runs really slow and almost crashes my machine, even though I have a powerful PC.

Has anyone here tried it before? If so, did you get a good performance? How?

I could do it perfectly in C++, but I need to use it in C#...

Thanks,
-Ricardo
