Hi,

I'm struggling with a problem. I want to catch a 'WM_COPYDATA' event that occurs in a C# application.
I send a data from a C++ application. The bridge is correctly done I think.
So, sometimes it works, usually when my C# application is active.
But most of the time, it doesn't work, because when trying to catch the appropriate WM_COPYDATA message in WndProc overrided method of my C# application, the program stays catching a couple of other messages like: WM_WINDOWPOSCHANGED, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_ACTIVATE and so on.
Doing so, it almost never catch the WM_COPYDATA message that I sent from my C++ application.

Can you help me please ?

Thanks.
P.S.: I catch messages in my C# application like this:

protected override void WndProc(ref Message m)
{
string g = m.ToString();

if (m.Msg == WM_COPYDATA)
{
// instructions.
}
}

You really need to add:

else //Let the normal windows messaging process it.
  {
   base.DefWndProc(ref m);
  }

So that other windows messages get handled properly. I don't know if this will fix your issue or not. I am not sure if your C# app will receive the message if it is not active.

I already had:

base.WndProc(ref m);

Isn't it supposed to do the same thing ?

I tried what u asked me, but my c# application doesn't receive any information back.

thx.

It is the same thing, I guess you didn't post that code in your previous post.

Yes, I didn't post it.

I also tried to use PostMessage instead of SendMessage. But I don't get appropriate results.

Any idea ?

Thx.

Have you looked at this article at all:

It seems this is doing what you want to do.

Math/Algebra library: parsing and proccessing functions

I'm writing a program, where the user should be able to enter a function (for example x^2 + 4*x+3) in the interface. The function needs then to be parsed, a derrivation has to be found and the results computed by using different parameters.

Don't wanna write a parser by myself, can somebody suggest a parser/library for such things?

HA-HA )
I've looked on google but all what I found yet are parsers, that evaluate the function with pre-defined variable-values. If a variable is unkown and I just want to operate with the funktion, without inserting any values - they fail.

I'm sure there schould be anywhere the right one, but I'm loosing time searching for it - if someone knows any it would be nice )

Setting a variable value from an array.

I am currently writing a text adventure in c#.

What I have is a 3 by 3 array with 0's and 1's in a specific order.

010
111
010

Basically anywhere theres a 1, thats a valid location for the person to move to.

What I need is a way to pull the value out of an array position say array[1,1]

This isnt all the code but you get the picture.

int intWall = 0;

intWall = arrWall[x,y];

if (intWall == 0)
{
Console.WriteLine("You can't move that way.");
}

// I need some way of putting the value of the x,y spot in the array to the variable

Do you need this:

arrWall[1,0]=0;<br />
arrWall[1,1]=1;

jblouir wrote:
int intWall = 0;

intWall = arrWall[x,y];

if (intWall == 0)
{
Console.WriteLine("You can't move that way.");
}

You can write just this:

if (arrWall[x,y] == 0)<br />
{<br />
Console.WriteLine("You can't move that way.");<br />
}

Odd I thought I tried that, thanks =).

I am pretty sure I tried to check the value using...

if (arrWall[x,y] == 0)
{
etc..
}

and it came back with something like cant perform on

Its working now though thanks for the help! =D

may you try to cast the value that way:

if ((int)arrWall[x,y] == 0)
{
etc...
}

i think it should work!

Application is closing when i hide it...!

Hi!
i am facing a problem in hiding the main form. I am using notifyicon control to show the application in system tray. When user minimizes the application it hides the main form and displays the notifyicon in system tray, and on clicking the notifyicon, maximize & unhide the main form...

all this was working fine until i added a splash form at start. On load event of splash form i am performing some functions and then hide the splash form and show the main form using frmMain.ShowDialog() and after it close the application.

now when i minimize the main form it hides the form as expected but soon after hiding the form it closes the application.

after debugging it showed that when i hide the main form, it closes the form and returns to the place from where it was called (load event of splash form) and then close the splash form.

Please tell me how to handle this situation?

Thanks in advance...

hmmmm i have a feeling this is going to be start point and/or main thread related.

seems like the splash screen you added hasnt really been added to the main form, its taken over from it and the main form is not a sub-form.

[STAThread] may be also causing you problems

sorry i cant really help any more than that, i've got a meeting to get to (lucky me)

Hi,

please explain, or better yet show code, for Main, splash screen and mainForm
(constructors, timers, show/hide/visible stuff).

Thanks for reply....here's some code of splash and main form...

Code for load event of splash form:

private void frmSplash_Load(object sender, EventArgs e)
{
// .....
// Some functions....
// .....
this.Hide();
Form objFrmMain = new frmMain();
objFrmMain.ShowDialog();
Application.Exit();
}

Code for resize event of main form:

private void frmMain_Resize(object sender, EventArgs e)
{
if (this == null)
{
return;
}

if (this.WindowState == FormWindowState.Minimized)
{
this.Hide();
notifyIcon1.Visible = true;
}
else
{
this.Show();
notifyIcon1.Visible = false;
}
}

Code for restoring the main form:

private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
ContextMenuStrip cms = new ContextMenuStrip();
cms = contextMenuStrip2;
cms.Items[0].Visible = true;
cms.Items[1].Visible = true;
}
else
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Show();
notifyIcon1.Visible = true;
this.WindowState = FormWindowState.Maximized;
}

// Activate the form.
this.Activate();
this.Focus();
}
}

Following is the code in Program.cs, this may also be useful...

[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new frmSplash());
}

When i minimize the main form, frmMain_Resize event is executed and after this frmMain closes and the Application.Exit() is executed and application closes.

Hope this helps you understanding the ptoblem, looking forward for your reply...
