led mike wrote: abusing async requests where the use model does not fit
I was thinking more Microsoft's AJAX dummy tools, rather than Async JS/XML proper. A solid system should be able to do stuff for which it was never intended and keep kicking; you should be able to hand it to an ambitious little code monkey and get back a working system, not a pile of monkey crap. After all, it's been done in Windows for years  . What concerns me is that if you throw a bunch of (Microsoft's) AJAX controls on a page, those being as close as we'll get for a long time to a unified standard, after a certain critical mass the chance of some major error occurring increases; throw in third party controls and you've really got a mess. On the other hand, if you add an extra button to a crowded Windows form, your concerns are primarily stylistic. The whole system is so damned incestuous - putting everything on a single page, whether you use Iframes and their various relatives as separating mechanisms or not, is like writing an entire Windows form's functionality inside the form - it works for simple stuff, but if you try anything interesting, you really have to cover your, um, source code. Blockquotes work alright, but again, why jam a bunch of functionality into form_load? Split it into separate pages and think of them as classes with built-in return functionality. Or don't.
As for DHTML, I've worked with it. Do you really want to go back to that?
As for setting me off, just about anything code-related does it. I did just spend five hours on a Greyhound bus in driving snow, if that's an excuse. Two months and my commuting days are over...
Oh, and you know something else? Web parts... but that definitely belongs in the rants section.

i would personally not create the thread in that way at all, create the thread using async cals and callbacks, especially if displaying a please wait message...
might help...

Hello guys I have to use datagrid (VS 2003) (not datagridview object) to modify an old project.
Prob 1
I need to capture double click event either on the row or the cell in the DataGrid and then read the
contents from that row. I have seen the props in the DataGrid object and I can't see any double click events like there are in datagridview object in VS 2005.
Prob 2
I need to change the width on individual columns in the DataGrid but can't see any property, but PreferedColumnWidth which sets the size for all the columns.
If any body can help me to fix this. It will b highly appreciated.

Problem 1:
You'll have to use a little trickery. Inject some javascript that handles the click events on the client side and causes a postback, or a callback as necessary.
Problem 2:
You'll need to handle the RowCreated event and set the column width there.

Bro.
The app I am woking on is a WinForm and not webbased.
second I can't c "RowCreated event" in the event list of DataGrid Object.
o O º(`'·.,(`'·., ?,.·''),.·'')º O o°
»·'"`»* *? t4ure4n ?* *«·'"`«
°o O º(,.·''(,.·'' ?`'·.,)`'·.,)º O o°

Sorry, I assumed Web since when not specified that is usually the target here.
After the DataGrid has been bound loop through the columns and set the width.
And don't use Bro please

Hi all,
I have to select * from a table where customer_name is not equal to John .
Is this a good query? :
select * from table where customer_name != john
thanx

The SQL forum would probably be a better place to ask a SQL related questions.
!= is not recognized by SQL, you need to use <>

And you are NOT advised to use 'select * ' either.

Giorgi Dalakishvili,
Just wondering, but whys it not recommended to use "select * from" in SQL?
Regards,
Gareth.

As far as I remember when you use "select * from" sql server has to find out all the columns that are present in the table you are querying. On the other hand, when you list the columns you wish to select sql just selects them, in other words it doesn't need to perform one extra step. So it is better to specify the columns you wish to select rather then use * even if you need all columns from the table

Giorgi Dalakishvili,
Ahhh, thanks for that. I thought it might of been a security risk of some type. Learn something new everyday and all that!
Regards,
Gareth.

i was working on a project and want to develope an application using visual studios 2005 that can search through all files on my windows system and get all shared is there any class that can get this done for me
|
|
|
|
|
Hi,
for searching through file system, I think you can use
Microsoft.VisualBasic.FileIO.FileSystem Class by adding reference of
Microsoft.VisualBasic.dll, it will give u very flexible way for handling
files and folders.
Regards,
Amar

Wow I don't really know what you are trying to do. I could make some wild guesses based on that but:

What else are you quite new to? If you are new to software development then I suggest you are tackling a far more complex project that is appropriate for a novice software developer.

Hi Tyrone,
You'll probably have to write and install something on the client. Javascript, and by extension pretty much anything on the client side, can't poke around on a client computer for information, for obvious security reasons. Research Activex objects; I've never used them, so I can't give you more help than that, but it's where you'll probably want to start.

Ok, hopefully, this will be an easier problem to solve. I have a program that has a NotifyIcon control. When the user completes the MainFrame form, the window minimizes and then hides. I want to be able to double-click the notifyicon to make the window reappear. I also want to be able to right-click the n-icon and have my context menu strip show.
Now this works perfectly well when the window (MainFrame) is minimized, but once the user completes the MF form and the window hides, the n-icon does not respond. Here's my code:
<br />
private void MainFrm_Resize(object sender, EventArgs e)<br />
{<br />
if (this.WindowState == FormWindowState.Minimized)<br />
Hide();<br />
}<br />
...<br />
private void TB_Icon_DoubleClick(object sender, EventArgs e)<br />
{<br />
Show();<br />
WindowState = FormWindowState.Normal;<br />
}<br />
...<br />
private void TB_Icon_MouseUp(object sender, MouseEventArgs e)<br />
{<br />
if (e.Button == MouseButtons.Right)<br />
{<br />
ContMenuStrip.Show();<br />
}<br />
}<br />
...<br />
private void ContMenuStrip_Click(object sender, EventArgs e)<br />
{<br />
Show();<br />
WindowState = FormWindowState.Normal;<br />
}<br />
<br />
<br />
Now, keep in mind that after the user completes the MainFrame form (clicks the "OK" button), a loop is constantly running. Nothing happens when I double-click or right-click on the notifyicon. Thanks for the help.

The double click event for the notify icon should be MouseDoubleClick.
The TB_Icon_MouseUp method should not be needed - assign ContMenuStrip to TB_Icon's ContextMenuStrip property.
