Great.
The very first image[^] I looked at has a bill board for a shop in Ghent that is still there; I have bought some locs there once. Normally I go shopping in Germany...

Sure, use System.Timers for your timer and System.IO for CSV file.
|
|
|
|

Sounds like you are doing some profiling/tracing. Google those terms, perhaps in combination with "C#" and anything more specific you are interested in. Or do as others say and create a timer that appends to the CSV file.

Hi boy,
try this.
using System;
using System.Windows.Forms;
using System.IO;
namespace WriteCSV
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
this.timer1.Enabled = !this.timer1.Enabled;
}
private void timer1_Tick(object sender, EventArgs e)
{
FileStream fs = new FileStream("test.csv", FileMode.Append, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.WriteLine(DateTime.Now.ToString());
sw.Close();
fs.Close();
}
}
}

Hello,
I'm developping a sync solution enables filtering but is there any way to load the changes form the source database into a dataset and mark the deleted or updated rows to transfer this dataset to client and update its data?
I've tryied to use the Microsoft Sync Framework but it does not allow filtering even if I use a custom provider because in my scenariro I want to sync a subset of the data on the server with a client and vice versa sync framework depends on primary key only which not acceptable here because when deleting or updating rows these rows may deletetd for another user in the source database the primary key in the client will not be the same as the server this is because I want to select the changes as xml and populate the dataset soit can mark the deleted rows and updated .. ctc

Normally in this situation there is a timestamp field, or some other type, in the database that is used to tell if a row has been updated. Add a where clause to your query to get the changed rows.

Yes I've done it but I want to transfer the data to the client as a dataset holding the changes so how I tell the dataset that certain row is deleted or inserted or updated when it reads the xml file and not aftr loading the data throw the rowstate property

I don't understand what you are asking. You have all the tools, what is the problem you are having?

I select the modified data from the sql server as a xml I've added an attribute to each row to tell me its state when I load this file to a dataset it does not read the stated it marks all rows as Added by default so if I want to change the state I have to loop over the table and change the rowstate property my question is Can I change the state when the data set loads the xml file or I have to loop over the table after population?
Dad

Why are you returning XML that is then placed into a dataset?  This makes no sense at all. Its like converting an int to a string then back to an int.
Add the column to the select query then it will be in the dataset already. Otherwise, no, there is no other way except to iterate through the rows.

I've tried the xml to let me choose an intermediate method to tell the dataset the state of rows but it will be more efficient if it loads the data directly but If it does, also, How can I tell the row state? this data set will be transferred to a client where another adapter will update the client database so the dataset must tell the state of the rows which I cant do when loading the data because the column which tell the state is invented by my sql script and it does not belong to table so the data set will trait it as a normal column.

You are making this out to be much more difficult that it really is. This issue in particular and the entire architecture of your application from the sounds of it.
If the client can call the database to update the records why are you placing this intermediary step in between, access from the client, or better yet from a properly constructed dta accsss layer.
hadad wrote: invented by my sql script and it does not belong to table
YES it does. If it's in the select statement is will be in the dataset.
RTFM!!

Hi guys does anyone know how to check if a sortedlist
is empty or not?
I tried using the 'capacity' and keys|values 'count' property but none work
Anyone with a different approach?
help
Morg
|
|
|
|
|
Capacity won't tell you if it's empty or not (if it's 0 then it's empty, but it could be empty and > 0).
Count should - what doesn't work about it?

Cool it works fine now...it was just logic

Use the Count property:
SortedList<int, string> sl = new SortedList<int, string>();
sl.Add(4, "four");
sl.Add(3, "three");
MessageBox.Show(sl.Count.ToString());
Gives "2".
SortedList<int, string> sl = new SortedList<int, string>();
MessageBox.Show(sl.Count.ToString());
Gives "0".

Why do you think that the Count property is inaccurate? Can you give an example of the exact problem you are facing.

|
|
|
|

The count property can determine whether the list is empty or not if it is 0 so the list is empty

Rule one: If you are going to post code fragments - especially long code fragments - use the "code block" widget (or <pre> </pre> tags) to preserve the formatting, not the "inline code" widget (or <code> </code> tags).
Rule two: From a quick scan (which is all I'll do with unformatted stuff), it is a good idea when reading in an image file to keep both the image, and the thumbnail - not keep the thumbnail and throw away the image... Would it surprise you to know that a thumbnail is 80 x 80? Suggest anything about you problem?
