hi guys! ckeck out this
i have an app with 2 forms and a database with a table
in the first form i have a datagrid of the table which i manually put it in the form from tha Data Source window, you know what i mean... the insert,update and delete will be done in the second form via textboxes, i use dataset.datatables etc to do the job
so,the problem is when i do insert,update or delete in the second form and then close it, the datagrid in the first one shows the old data, i try the refresh() method but still nothing,
what shoud i do??
thank you i advance

If you have stored updated data in the grid, then rebinding to your data source is going to show updated data. I assume that the refresh method does not do that, I have never used the ugliness you're talking about, I write proper data layers.

I reread the table from the database and reload the datagridview (assuming winforms).

the form which incclude the datagrid does not close when i open the form2 to do the insert,update and delete, so can i reread the table since the constructor of the form1 doesn't recall?
i want when i click the save button of the form2 the datagrid to refresh at the same time

You need to buy a very basic C# book and read it. Of course you can rebind your control. The nasty stuff you're using, which puts your SQL in your presentation layer, probably changes how you do that, but it has to be possible.

If form2 is not modal, then you need a delegate to make that work.

maybe you dont understood me my friend. the datagrid is in form 1. the upadating,inserting and deleting in the form 2, when i press the save button in the form2 then the datagrid in the form2 must be update, its not only rebinding the control. how can it done when i click the save button in the form 2.
also the form with the datagrid mustn't close at all
i hope you understand

dude do you have datagrid in page one alone or do you have that even in page 2.
if you have the datagrid in page two you can give the datasource to the grid on click of save button
even then if you are not able to get the updated records, you first need to check the SQL table which you update. verify if you are updating the table in the database or just the dataset.

no, datagrid in form1 and the insert,update in form2
tha form1 must be open all the time,
i cklick tha save button in form2 and i want the datagrid in form1 to be updated, and i will say it again, without closing the form1

In that case i think you might be binding the records by checking for is postback.
try binding the data removing the ispostback block that should help. if you feel that this is not helping out please post the code that you have written so that anybody who looks at that can help you out.

the datagrid of the table is made aytomaticly when i drag and drop it from the datasourse window
so he code that appears is
private void Form2_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'programmersHeavenDataSet1.Article' table. You can move, or remove it, as needed.
this.articleTableAdapter.Fill(this.programmersHeavenDataSet1.Article);
// TODO: This line of code loads data into the 'programmersHeavenDataSet1.Article' table. You can move, or remove it, as needed.
this.articleTableAdapter.Fill(this.programmersHeavenDataSet1.Article);
}
private void articleBindingNavigatorSaveItem_Click(object sender, EventArgs e)
{
this.Validate();
this.articleBindingSource.EndEdit();
this.tableAdapterManager.UpdateAll(this.programmersHeavenDataSet1);
}

My task is as follows...
I have 2 data files a Source (A) and a Destination (B) both located in the shared network drive.
A is a data file (plain text) between 2GB and 3GB made up of records of fixed size.
A is always being written into by other processes (new records being appended at the end).
I would like to read through the whole file A, read each record, leave what I still need and archive the rest to B.
There is a 10 character string I can use within each record as a filter.
My question is, is there a (fast, as in run-time fast) way to do this in C#? I have been trying to do this with MMF but I'm beginning to think it's overkill?
Thanks for any help.

Hey, Im making an application to telnet my NAS and punch in some simple commands like chmod etc . Ive been googling for the last two hours and all ive found are fully functional telnet clients which i have no hope of integrating into my tiny application .
Can anyone point me in the direction of a telnet activex control or even suggest a way of using my application tto punch commands automatically into an existing telnet client like putty ?
Thanks

No, not really. I wrote my own, but it's not ready for publication.

it's possible to load a form as a desktop background?
if possible how i do it ?
thanks

No. You might have been able to do this on XP and below using Active Desktop and a webpage, but Vista removed this possibility and replaced it with the sidebar

You can use an IMAGE of your form. Taking over the users desktop is definately frowned upon.

I think YouTube has a data API for that. Never used it though - you'd have to research that yourself

I'd like to write a windows pc application that will be able to communicate with another device using TCP/IP via a USB connection. The PC application would be a client and the remote device the host. Can anyone point me in the right direction on how to get started with this or to some articles to read? I don't really have any experience with network programming but I'm quite comfortable programming in C# otherwise. Is this going to be a major undertaking?
Thanks in advance

Well, the .NET Framework makes network programming a virtually straight-forward task, not like alot of other programmers would have you believe...
A few months ago I found a link to an article that's very similar to what you're trying to accomplish. If I can find it again I'll post it on here.

I would have people believe differently. If you can manually forward all relevant ports on all computers that will have a listening socket then it's easy enough, but otherwise NAT will get you.
edit: there probably isn't going to be NAT between an USB thing and a computer though, so that's 1 problem less.

If you have drivers that allow you to network two or more machines over USB, then you don't have to do anything in your code. TCP/IP is the carrier for your data, abstracting the underlying hardware and links away. You don't have to account for the link type at all.
After that, pick up a book on Windows Communication Foundation and Sockets Programming.
