You should ask this in the ASP.NET forum, not here.

Hi All,
I am facing a vary basic problem with timer. I want a timer to start counting an integer i with a start-button-press and stop counting with a stop-button-press. Then start counting again with start-button-press and so on. The code looks like the following sample snippet:
int i=0;
Timer tmrTest = new Timer();
public void OnTimerEvent_test(object source, EventArgs e)
{
i++;
txtCounter.Text = i.ToString();
}
private void btnStartTimer_Click(object sender, EventArgs e)
{
tmrTest.Enabled = true;
tmrTest.Interval = 500;
tmrTest.Tick += new System.EventHandler(OnTimerEvent_test);
}
private void btnStopTimer_Click(object sender, EventArgs e)
{
tmrTest.Enabled = false;
}
The problem is on start-button-press first time it counts i as i+1 but in second start-button-press it counts i as i+2, for 3rd it's i+3 and so on. But I want the counting to be always i=i+1;
May be this is a very simple issue while handling timer but I failed to get any solution. Please help me to solve this out. And tell me the reason, why is this timer behaving like this?
Thanks in advance

Hi, this line should be executed only once ever. The way you have it, each time you click
the start button, it will add a handler to the event, so after N starts, each tick will
increment the counter N times.
You may want to read my article on events and delegates.

The first step is to specify what it should actually do.

We are having a Crystal Report with Unicode data (Indian Language-Marathi) as
an output.The report is getting generated but at line break a word is getting
cut instead of getting wrapped in next line.
We are working with Crystal Report which is a part of VS 2005.
Please suggest the solution either in Crystal or any other Reporting
method/Tool.
Thanks

Hi,
I'm transmitting Live video over LAN by joining multicast group address "224.0.0.1".At client side, for receiving video I used same group address.
I've read that multi Cast range is from 224.0.0.1 to 224.255.255.255 but I tested my server application with max. 3 clients.
Can any one tell me the video which is transmitting at this address, How many systems can preview it.
And what should be hardware constraints

I am loading 300 pictures inside the listbox but when i scroll up and down
all the way the memory goes from 32,000k to 689,000k and up and also it doesn't come down.
Form1.cs
LisboxClass lb = new ListBoxclass();
lb.Size = new Size(200, 524);
Form1.Controls.Add(lb);
string[] str = Directory.GetFileSystemEntries(Application.StartupPath + @"\images");
lb.BeginUpdate();
PictureControl picControl;
foreach (string s in str)
{
picControl= new PictureControl(s);
lb.Items.Add(imgcontrol);
}
lb.EndUpdate();
This is how I am drawing Items
Bitmap b = new Bitmap(800, 800);
Rectangle rect = new Rectangle(0, 0, 120, 80);
private void ListBoxclass_DrawItem(object sender, DrawItemEventArgs e)
{
((PictureControl)Items[e.Index]).DrawToBitmap(b, rect);
e.Graphics.DrawImage(b, e.Bounds.X + 40, e.Bounds.Y + 5, 120, 80);
}

For each image file you load, create its thumbnail in the stream to reduce its memory used, then draw to your listbox. Or you can store that thumbnail in imagelist (as cache) then draw to your listbox.
according your code you have to manage at least 300 object that contains image, but in my opinion i will use one object that manage all 300 image
hope it helps

Hi,
your code will rescale the original images over and over, every time DrawItem is called.
This is an expensive operation, both for CPU cycles and memory. I suggest you calculate the
images you need just once, at the right size, and keep those available in each item of your ListBox.
That way, your ListBox will scroll much faster, and your memory footprint will be lower.
BTW: not sure how you observe your memory footprint, it not coming down is not necessarily bad.
BTW2: the Image (and hence also the Bitmap) class offers a Dispose() method, you should call it
explicitly when you are done with the Image (Bitmap) for better performance too. Think of it
as closing a file.

Hi
please help me abuot pdf expire?
for example we want expire the pdf file (TTL=10 days)
thanks

What are you trying to do ? You can't expire a PDF file, AFAIK.

Do I Allocate An Expire Date For a PDF File? (SIMILAR Trial Program) How?
Thanks

I don't think that a PDF file has any property like expiration date.
If it has, you will probably have better luck looking for it in a different forum, as it has nothing at all to do with C# programming...

Hi all
I use an error provider in my win form in order to validate some text
boxes value.
My problem is this:if the user input something wrong then the error
provider shows him a
notification,It is logical,but when user correct the value the error
notification is still visible to him
and the user think that he made a mistake again.The same problem is
happened in DatagridView.
what should I do to prevent this?(the error provider disappeared when
user correct his value when he entered)
the following code is a piece of my code which I use:
private void txtName_Validating(object sender,
System.ComponentModel.CancelEventArgs e)
{
if (!IsNameValid())
{
e.Cancel = true;
}
}
private bool IsNameValid()
{
txtName.Text = txtName.Text.Trim();
if (txtName.Text == string.Empty)
{
erp1.SetError(txtName, "Name must not be blank.");
return false;
}
else
{
erp1.SetError(txtName, "");
return true;
}
}
---------------------DataGridView-----------------
void DataGridView1CellValidating(object sender,
DataGridViewCellValidatingEventArgs e)
{
if (dataGridView1.Columns[e.ColumnIndex].HeaderText=="Input")
{
char[] chArray=e.FormattedValue.ToString().ToCharArray();
bool flag=false;
foreach(char ch in chArray){
if(!Char.IsDigit(ch)){
flag=true;
e.Cancel=true;
break;
}
if(flag==true){
dataGridView1.Rows[e.RowIndex].ErrorText = "Invalid Product
Image";
dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText =
"The file name must end with '.gif'.";
}
else
{
dataGridView1.Rows[e.RowIndex].ErrorText = "";
dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].ErrorText
="";
}
}
}
}
|

|

At the beginning of the validation function reset the error for the control by doing the following
erp1.SetError(txtName, ""); // an empty string hides the error provider.
private bool IsNameValid()
{
erp1.SetError(txtName, "");
txtName.Text = txtName.Text.Trim();
if (txtName.Text == string.Empty)
{
erp1.SetError(txtName, "Name must not be blank.");
return false;
}
else
{
erp1.SetError(txtName, "");
return true;
}
}

Hi,
How can i simplify a path for filexpto.txt?
c:\folder1\folder13\folder137\folder1376\filexpto.txt
..\\folder1376\\filexpto.txt ????
.\folder1376\filexpto.txt ????
how do you do it?
|
|
|
|

This won't truncate the path the way you are asking, but it will compact it. You need to call the PathCompactPathEx from shlwapi.dll.
[DllImport( "shlwapi.dll" )]
static extern bool PathCompactPathEx([Out] StringBuilder pszOut, string szPath, int cchMax, int dwFlags);
static string CompactPath(string path, int length)
{
StringBuilder sb = new StringBuilder();
PathCompactPathEx(sb, path, length, 0);
return sb.ToString();
}
