Can someone pls tell/show me how to minimise a window/form to the taskbar.
|

When, I say taskbar, I mean the system tray, where the part of task bar where date, time, and Icons are displayed at the right hand corner.

Search CodeProject for NotifyIcon. When minimized, set the NotifyIcon of the form, and set the forms "ShowInTaskbar" property to false.

i made a mistake in the code
the correct code is
my application works like this,i have a datagrid,a dropdownlist and a submit button,my
dropdownlist contains a list of intervals eg(100-999)(2100-2199),in order for the user to
add to the grid he has to choose an interval from the dropdown,and the id for the row he's
adding has to be in that particular interval.
i have a method/function that checks if the id is in the chosen interval
private void checkvalue(int value)
{
switch(DropdownList1.SelectedIndex)
{
case 0:
if(value>=100 && value<=999)
{
}
else
{
Label1.Text="id not in required interval"
}
break;
case 1:
if(value>=2100 && value<=2199)
{
}
else
{
Label1.Text="id not in required interval"
}
break;
}
and the button clickevent
private void ButtSubmit_Click(object sender, System.EventArgs e)
{
checkvalue(num);
//adding to the grid
collection.add(num);
...
}
when i click my submit button ,and into the checkvalue callfunction,if the value is not in
the required interval ,it prints the text message but still continues to add the row to my grid
i want it to stop after it prints the message and exit without adding the row to my grid,what do
you suggest i do.i hope this is clear enough
thanks
regards paula

You need to return a boolean (true or false) from the checkvalue method
private bool checkvalue(int value){
if (the value is in the range){
return true;
} else {
return false;
}
}
//that's it.

Hi.
I have a requirement to store files (they happen to be .pdf files but could be word/excel etc) on an application server.
These files are to be requested from the presentation layer.
When the user clicks a report, a reportid is passed to the middle tier, whereby it retrieves the associated filepath from the DB and then goes and loads the file.
My problem is that I am not sure how to pass this file back to the presentation layer. What I would like to do, is spit out a stream to the response object so the file just opens in the users browser (rather than saving a copy on the web server and then allowing the user to either Open/Save).
I thought a filestream or binaryreader object would do the trick, but if i pass this to the presentation layer, the second i call the .Read methods, ill get an exception as the file doesnt exist on the web server !
Can anybody suggest the best way(s) of achieving my goals ?
Thanks.

You make no mention what your presentation layer is, however from the context I assume you mean a web page.
If you set the Response.ContentType to the proper file type and use Response.OutputStream it should work.

Sorry, yes, an ASP.Net web page. Im am OK with sending the stream to the response object once ive got it...my problem is actually getting the stream object from the middletier in the first place.
PresLayer - Requests doc id 1
AppLayer - Receives Request
- Obtains the path of the file from the db
- can open the file (filestream?)
- RETURNS THE FILE/STREAM
PresLayer - Spits stream out to response object.
My question is how i can pass the binary data back from the applayer to the preslayer. Eg, surely if i pass the filestream back (as an out parameter for example), the minute i call .Read on the front end, ill get an exception because the file actually exists on another machine ?!

Provided that permissions are set correctly you should be able to read the file into a stream and pass it to your presentation layer for display via Response.OutputStream

Hello,
I'am using System.Windows.Forms.ComponentModel to display the Attribs of my object in a Propertygrid. Please read the following code snippets to understand my problem.
Node class:
[
CategoryAttribute("Instance type"),
DescriptionAttribute("Instance of")
]
public string InstanceOf
{...}
[
CategoryAttribute("Geometry"),
DescriptionAttribute("Position")
]
public Vec3 Position
{...}
---------------------
Vec3 class
[
CategoryAttribute("Vector props"),
DescriptionAttribute("X")
]
public double X
{...}
[
CategoryAttribute("Vector props"),
DescriptionAttribute("Y")
]
public double Y
{...}
----------------
My problem is now, that the PropertyGrid displays the Attribute Node.Position as String (it just calls its ToString() function). But i want, that the grid displays the Vector's Attributes, so that I can change them by modifing the it's values in the grid.
PropertyGrid.SelectedObject = Node results in the
following:
- Geometry
Position 0,0,0
PropGrid I wish:
- Geometry
- Position 0,1,2
X 0
Y 1
Z 2

Hello,
I have a xml file:
<akis xmlns:sql="urn:schemas-microsoft-com:xml-sql">
<element><sql:query>SELECT @Element</sql:query></element>
<rows><sql:query>EXEC sp_ForXML @Element,'XML'</sql:query></rows>
</akis>
and I need to get the results of that.Is there any way to get them not by running the stored procedure but from the xml itself?
thaks in advance,
akis

Yes, you can query the database direct and have XML returned. You need to use IIS Virtual Directory Management for SQL Server. In the start menu, under SQL Server, there is a link called Configure SQL XML Support in IIS - that should get you started.

Hi, Am a newbie in c#. am facing a strange problem. I have a tabcontrol and on the first tab page, i have two controls laid side by side. To the first control i have set the anchor as top & left, while to the next i have set it to top and right. When i run the application on windows 2000 prof,(my dev machine) all is fine, i can see the controls as they are supposed to be. But when i open the application in windows XP, the second control has lost its right anchor and it goes beyond the tabpage and tabcontrol boundaries. If i opne the designer in the windows XP machine and may few unrelated changes and save it, it then runs normally on windows XP, but fails to work properly on windows 2000 professional. Am not able to understand what i am doing wrong.
any help please?
