are you looking for an exact grid of pixels in the image or something softer like a thing that looks to a certain extent like the other image.
If you have both images as bitmaps then take the colour value of pixel (0,0) in the image you are looking for. Then search the first image till you find a match. When you have a match check to see if pixel (1,0) matches the next pixel along in the image. If it does go to pixel(2,0) etc. If the pixel doesn't match go back to searching the image for the colour value from Pixel(0,0) again until you either find a match or run out of image to search.

when program startup, I will give a parameter to main meth.
then this parameter will transfer to MainForm(parameter of "Application.Run" method).
But if program has run, how fransfer this parameter or get the MainForm?
|
|
|
|
|
Do you mean you want send some values as parameters to Main?
This can be done like: Goto "Project properties -> Debug -> command line arguments" and put values separated by space.
|
|
|
|
|
yes.
But i want to send this parameter to WindowsForm yet.
|
|
|
|
|
Well in that case, create a parameterized constructor of the form you are calling in Applicatio.Run() and send the values.
|
|
|
|
|
Thanks.
But you said the way can achieve at startup only.
If program has run, how send parameter?

Didnt got that.

Because my winform program can run only instance.
So I checked in main of program class.
if there is a instance in proceeding, can I get the main form of this instance?
Or other way?

What kind of information are you trying to pass, and when?

Anther program will call my winform program, then open a form (is not MainForm ).
the caller will send a string to my winform.
when the caller calls, my winform maybe has run, or does not run.
|
|
|
|

If the program is already running you still send the parameter the same way, the constructor. The only difference is that Application.Run() won't be calling that constructor. You will have to call it yourself, how is up to you.

But I can not get the form.

Hi I have an object I need to serialize in XML.
In my object I have some decimal fields that in the XML file must (MUST) appear with 2 decimals.
Is there a way to tell the serializer he must format all decimal that way?

Hi,
Project
-------
I have this list box that will get a list of items from a database. Upon choosing an item, it will populate the DataGridView with the data, this data is different for different items, e.g. one might have a size field and another wouldn't or an item might have 5 entries but another 9, etc. This populated data is from a table that has a unique ID (key), the field name, the field value and the foreign key to link to the item table.
Problem 1
---------
Currently, I'm trying to add an item into the database, how can I create a DataGridView that would allow me to add rows to it. If I bind it to a table I get the error that table.rows.add() is not allowed on a bound DataGridView.
I have to presume that I can just unbind the table and add the rows of data manually. I'm wondering if there is an easier way of doing it.
Problem 2
---------
Further to the above, if I want to edit an item, how can I go about adding a new row if the columns are bound. I require (during editing) that columns because more than 1 user might be editing the same item at the same time.
How would I go about doing this?
Anyone has any article to point me to?
Thanks.
Desmond

Answer to problem 1
-------------------
1. Add a datagridview to your form.
2. Dont add any column to it
add a quote to retrieve data from the database
1. connectionstring
e.g string conStr="Add the relevent connection to the database"
2. a function to retrieve the data. Create a class called it DataAccess
<code>
using system.data;
using system.data.oleddb;
public class DataAccess
{
public void Show(string sql, string con, datagridview dt)
{
}
}
</code>
Then you can call this class to pupulate any datagridview with any number of rows or columns without any modifications. If you want a complete quote let me know (lnkgoeng@webmail.co.za)

Hi all!
I´m trying to make a barcodeprinting and to make it possible i have to have a page foreach items in my listview.
my code look like this:
private void button1_Click(object sender, EventArgs e)
{
if (checkBox1.Checked == true)
{
PrintDialog theDialog = new PrintDialog();
theDialog.Document = printDocument1;
if (theDialog.ShowDialog() == DialogResult.OK)
{
printDocument1.DocumentName = listView1.Items.Count.ToString();
printDocument1.PrintPage += new PrintPageEventHandler(this.printDocument1_PrintPage);
printDocument1.Print();
}
}
}
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
foreach (ListViewItem lvi in listView1.Items)
{
DateTime dt = DateTime.Now;
string doktyp = "278";
Font font = new Font("3 of 9 Barcode", 20);
int St = Convert.ToInt32(domainUpDown1.Text);
Font font1 = new Font("Arial", St);
Font font2 = new Font("Arial", 10);
float x = 120;
float y = 100;
e.Graphics.DrawString("Jobb: " + label11.Text, font2, new SolidBrush(Color.Black), x + 500, y - 50);
e.Graphics.DrawString("Användare: " + label12.Text, font2, new SolidBrush(Color.Black), x + 500, y - 35);
e.Graphics.DrawString(dt.ToString("yyyy-dd-MM HH:mm:ss"), font2, new SolidBrush(Color.Black), x + 500, y - 20);
e.Graphics.DrawString("*" + lvi.SubItems[1].Text + "*", font, new SolidBrush(Color.Black), x, y + 85);
e.Graphics.DrawString("*" + lvi.SubItems[1].Text + "*", font, new SolidBrush(Color.Black), x, y + 105);
e.Graphics.DrawString("*" + lvi.SubItems[1].Text + "*", font, new SolidBrush(Color.Black), x, y + 125);
e.Graphics.DrawString(lvi.SubItems[1].Text, font1, new SolidBrush(Color.Black), x, y + 145);
}
}
With this code it overwhrites all the items in one page.
Thanks!
Best Regards André

Well, that's what you're telling it to do. You don't actually set x anywhere that I can see. It looks to me like all your labels will print in one location, because that's what your code does. x and y need to change to move your labels.
