I have already posted it and I guess it was a question itself.. anyway here it is again.
I am looking for something like below but I dont know how to do: Can you please tell me how do I do it in C# ?????????????
I have a software and I want to do....
1.. If Customer start the software and he will be asked to register on my site which uses a optin newsletter script. It will then store the member information into the mysql db.
2.. My software will then check if the member is registered.. if so it will then store his computer hardware id next to his email address in the database.
3.. Everytime the software will check the user details. this way he cannot share his copy of the software with the other.
4.. Also another point is if this customer is unsubscribed from my list he wont be able to use my software.
I only know that this can be done with a PHP interaction but dont know how to interact with PHP i.e. sending information to php from software and getting output from php to this software.

Hi all,
I have created an application in C#.
The application will be distributed to many users.
Some new features will be added later to the app.
Now i want to create a functionality that will be like
Whenever the app starts, it will first check on the server for
files with new version and should replace the existing with new version files. I want the app to automatically download the new dll's and replace the existing ones with these new ones.
Any reference or link or sample code in this regard will be appreciated.
Thanks & Regards,
Pramod

you can use setup factory setup 7.0 {Search it fro google} for your product! their you will find the auto update functionality inside which conncet your product to server....
|

That seems to be some product.
I don't have to use external products.
Is there any feature in .Net for this.
Or some customized code?
Thanks & Regards,
Pramod

If the app is 2.0 based you can use Click-Once. Otherwise look at the Updater Application Block from Microsoft's Patterns & Practices group.

What do u mean? throws an exception, hangs?
From what i know, you should never use a non UI thread to update the UI, it causes it to deadlock.

Hi thanks for the speedy reply 
No, it does not even get an exception, nothing of that sort and it does not even hang. emmm
this is very strange....

It's not safe to access UI controls from threads other than the one they were created on. It mostly results in a freezing UI or other strange things. You're lucky nothing of this happened in your case. As there are many other people like you who weren't aware of this problem and accessed UI controls from other threads, it's no longer allowed. Use Invoke or BeginInvoke to update your label. This article[^] should help you.

Richtextbox scenario:
Two RTB's with syncronized scrollbars. I get scrollinfo from the left and use that position to update RTB2 on the right. When i call SetScrollInfo for RTB2 the Scrollbar seems to move to correct position but it doesn't actually scroll down the text like it's neighbour on the left.
Can anyone tell me why or what I'm doing wrong?

Hello
SetScrollInfo doesn't actually scrolls. It changes the scrolling parameters as the name implies. Yes the little thumb moves up and down but it doesn't really scroll the content of the associated control. Revise the answer I posted to your earlier post, maybe it would help.
PS.
I guess you are using API calls? Why you jump low level that fast?

Deleted row information cannot be accessed through the row.
i use datarow for add,update,delete row and use oledbdataadapter and use this

{
if (this.BindingContext[ds_khane1, "Khaneh_1"].Position == -1)
return;
else
{
DataTable dt = ds_khane1.Tables["Khaneh_1"];
DataRow newrow = dt.Rows[dataGridView1.CurrentCell.RowIndex];
txt_name.Text = newrow["name"].ToString();
txt_family.Text = newrow["family"].ToString();
...
}note : i was use dataGridView1_CellPainting event and solved my problem,but why the above error shown me in dataGridView1_SelectionChangedevent and how to solve problem ?
thanks.

Hi all,
by making this.StartPosition = FormStartPosition.CenterScreen; works fine during design time, but when i change the size of form in load event, the form is not properly displayed in the center screen. eg.in the load event if i change the form's width and height. it did not display the form in the center screen, (ie upper left corner only centered with screen),
this is my code ( iam altering the forms width and height for the message to be displayed (custom messagebox)
private void CommnChkPopup_Load(object sender, EventArgs e)
{
this.Width = 460;
this.Height = 160;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
for (int len = 50; len < labelMessage.Text.Length; len = len + 50)
{
int i = labelMessage.Text.IndexOf("\n", (len - 50));
if (i > len || i == -1)
{
int j = labelMessage.Text.IndexOf(" ", len);
labelMessage.Text = labelMessage.Text.Insert(j, " \n");
}
}
if (this.Width < (labelMessage.Width + 92))
this.Width = labelMessage.Width + 92;
if (this.Height < (labelMessage.Height + 160))
this.Height = this.Height + labelMessage.Height;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
this.StartPosition = FormStartPosition.CenterScreen;
btnOk.Focus();
}

Hello
Here is a small code I wrote earlier to do the same thing:
Top = Screen.PrimaryScreen.WorkingArea.Height / 2 - Height / 2;
Left = Screen.PrimaryScreen.WorkingArea.Width / 2 - Width / 2;
Regards
