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;
?

}
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!

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...

Affan Ahmad Toor

ShowDialog is the problem. It stops blocking when the form is closed OR hidden. Basically, it's the wrong method to use in this situation.
There are plenty of ways to set this up, but here's one suggestion:
<br />
static void Main()<br />
{<br />
...styles and such...<br />
frmSplash splash = new frmSplash();<br />
Application.Run(splash);<br />
frmMain main = splash.GetMainForm();<br />
Application.Run(main);<br />
}<br />
In frmSplash:
<br />
private frmMain _mainForm;<br />
public frmMain GetMainForm() { return _mainForm; }<br />
In frmSplash_Load (Or wherever you want to do the actual work):
<br />
_mainForm = new frmMain();<br />
...<br />
this.Hide();<br />
Basically, the sequence of events here is:
1) Main() runs an application loop on the splash form
2) Splash form, once loaded, loads the main form
3) Splash form hides itself
4) Main() continues, and grabs a reference to the main form
5) Main() closes down the Splash form (It was just hidden)
6) Main() runs an application loop on the main form
I'm sure there are many other, and better, ways to do this, but here's the first example I came up with.
ADDENDUM to clarify: The point of this, is that if your frmMain instance is called from an Application.Run() instead of a ShowDialog, the application won't exit until it actually closes, so you can hide it all you want.

Hi!
thanks for help, it solved my problem and now my application is running perfectly...I just had to make a small change in your given code:
Ian Shlasko wrote: In frmSplash_Load (Or wherever you want to do the actual work):
_mainForm = new frmMain();
...
this.Hide();
"this.Hide();" was not allowing the "frmMain main = splash.GetMainForm();" to execute, it was not returning control to Main(), i replaced it with "this.Close()" and now it is working fine....
Thanks again...Take Care, Cheerz,

Affan Ahmad Toor

? has the forum put your post in the wrong place or have you just provided no information to really understand what your on about :P
Are you talking about converting VC++ code to C#?
Switching from programming in VC++ to C#?
Calling VC++ code from C#?

What I am trying to do is beable to type in to a textbox a password and then press Enter Button with that I would like to use my select statement of: "Select Count (*) As UserCount From UserName Where (Password = @Password)". This statement is in a sqldatasource and is connected to the control of the textbox on the form. I am however lost on how to continue to use the sqldatasource to tie up my enter button. I am just not sure how to use the sqldatasource in code to test for the query or even run the query. I have a example of the code I am writing if you would like to have it? I can email it to you. I would like to have to figure out some of this on my own so I dont want you to give me a complete answer right away. I want to and have to learn this!!!
Thank You

Is this an ASP.net app or windows app? That would make a difference in how you try to capture the enter key press. Normally you will need a login button. So your enter key press would just click the button. Then with your sqldatasource you set up a parameter that is set based off your username and password.
If you are doing asp.net, I have written an article on catching the enter key press.
http://www.codeproject.com/useritems/EnterKeyToButtonClick.asp[^]
If this is a windows app then you will want to look at the keyPress event.
Hope that helps.

Hello friends,
I am looked for an answer all over the net and couldnt find:
I have a datagridview (VS 2005) with VirtualMode set to true. its DataSource is a DataTable.
I have some data bound columns (not auto generated), and I add one unbound column.
I tried to sort this unbound column in without any succeed:
I tried to call the sort function of the dgv but I get an error that this is not supported. (to sort by unbound column).
I also tried to catch the dgv SortCompare event and to make the sort by myself, but i understand that this event doesnt fired in VirtualMode.
Please help me...
thanks a lot

i need to know what type of object , and retrieve it from textbox.text
i mean , text = "Test" is string object
text = 123 is int object
Like
if (Textbox.Text is int?????? )
debug.write ("int")
else
debug.write ("String")
123
|
|
|
|
|
If you are obtaining the data from a textbox it will always be a string until you convert to something else.
int x;
if( int.TryParse(TextBox.Text, out x) )
debug.write("int");
only two letters away from being an asset
|
|
|
|
|
if you expect some type you can try converting or parsing Text property of the textbox..
example:
bool success = false;
int outVal;
success = int.TryParse(Textbox.Text, out outVal);
if(success)return outVal;
and so on with other types..
life is study!!!

Good afternoon, I'm investigating about the ScrollBar and I have found some info that could be interesting, using a VisualStyleRenderer
VisualStyleRenderer render = new VisualStyleRenderer(VisualStyleElement.ScrollBar.ThumbButtonVertical.Normal);
Rectangle thum_pos = render.GetBackgroundExtent(e.Graphics, vScrollBar1.Bounds);
Does anyone know how to get the Elements Position of a control using the VisualStyles and overpaint them?...
All info and links will be welcome.
Thanks everyone

Hello,
I am new to C# programming (day 1). I have created a list view object dynamically, and added 1000 items to it. Now I want to copy these objects to another list view, which wasn't dynamically created. But I do not see the contents to get coiped. The following is the corresponding code.
ListView lv = new ListView();
for (int i = 0; i < 1000; i++)
{
lv.Items.Add(new ListViewItem("Hi there"));
}
listView1 = lv; <font color=green>
Nobody can give you wiser advice than yourself. - Cicero

|

you might need to call listView1.Refresh() after you assign lv to it
