That's because a script method doesn't return like this. What you need to do is supply a callback function which your javascript executes. Here's a sample page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
<script>
function keyPress()
{
var tb = document.getElementById('Text1');
if (tb.value.length == 2)
PageMethods.Getadata(tb.value, myFunction);
return false;
}
function myFunction(msg)
{
alert(msg);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True" />
<div>
<input type="text" id="Text1" onkeypress="keyPress()" />
</div>
</form>
</body>
</html>

Good Morning Pete
Thank you for your kind reples. its working like wonders. I have one last question. as you have seen i have been using a html textbox not an asp.net textbox. i see the asp text does not have the Keypress event , Is there a way that i can modify this working code to work with asp.net textbox defined like this
<asp:TextBox ID="Text2" runat="server"></asp:TextBox>
Thanks

win form setup creation???? you meen wix setup or you are writing your own ?!?!? there are definalty missing information. in wix you can set the banner image using the old one by just renaming the file

Do you mean in a Setup project in Visual Studio?
If so, right-click the Project and select View | User Interface (or us the menu View |Editor | User Interface)
In the properties of Install | Start | Welcome, "Banner Bitmap" is at the top. Just browse for what you want to use.

Hi,
This is most likely a basic problem but I can't get my head around it!
I am trying to construct a parameterized sql query that takes information entered from a textbox (the search box of the query) and adds it to the query before it executes.
What I would like to do is have the user search the 'CODE' column by entering something like:
= "CO" or "SO"
and have that added to my sql query after WHERE CODE
Any help greatly appreciated!
Joe

Erm. AFAIK the whole point of a parameterized query was to stop this kind of design so that's not going to work.
You'd have to go back to the old skool method of generating the entire SQL statement and firing it back to your DB. I'd check if you really need to as this is horrendously insecure. Can you just not create a search stored proc and pass in a search term on that?
|
|
|
|
|
Thanks,
I'll look at doing it through the stored procedure as you mentioned.
|
|
|
|

It depends on the type of database you are using as to how you tackle this, but you could add a temporary table that you use to add the individual parsed out elements in as individual elements, and then perform your main query using that table as a linked table, so you'd end up with SQL along the lines of:
SELECT ... FROM MyTable INNER JOIN MyTemporaryTable ON MyTable.Code = MyTemporaryTable.Code Also, rather than having them enter the codes, why not display them in a list that they can select from? This way you save them having to remember potentially archane code sequences.

Something like cmd.Parameters [ "@CodeVal" ].Value = tbCode.Text ; ?
|
|
|
|
|

Apart from being wide open to a SQL injection attack, this just won't work because it only applies to 1 value.

What makes a difference if it is individual module or one single module, if the functionality of the application is as simple as you describe it.
S.Bharath Ram wrote: I need to integrate them.
integrate what? the difference modules? Well, if you know how to write the modules, you will know how to integrate them

Keep the question as brief as possible. Provide more information whatever you have written.

This is easy. The other way round is what most people struggle with.

Edit : I have tried Dictionary<string[,], Texture2D> _lookup but doesnt work 
In xna I want to create a texture2D factory class so that I can grab preloaded textures on the fly without having to load them repeatedly.
I want something like
paddleTexture = GetData<Texture2D>(string foldername,string assetname)
for example:
GetData<Texture2D>("Sprite","paddle");
But I am having generic Dictionary troubles
I just cant seem to create its structure properly !
I have tried Dictionary<string ,Dictionary<string,Texture2D>> which is not what I want at all and I also load the data via a simple XML file:
<?xml version="1.0" encoding="utf-8"?>
<FileSystem>
<Folder Name="Sprite" Location = "Image/2D/Sprite">
<Texture Name ="paddle"></Texture>
<Texture Name ="ball"></Texture>
</Folder>
</FileSystem>
Can anyone help me with the structure of the generic Dictionary?
Thanks !

Just solved it Dictionary<string, int=""> and simply joined the folder and asset name into one string for the primary key
ie: lookup.Add(folder + assetname,texture);

I've been working on this one for two days, and I DON'T think it's a memory or disk-space problem.
I have a C# image-processing application that uses Win32 to do the graphics for speed. I restructured it so that different threads could work on different images in parallel (so far with just one thread), and got the above error message.
The Google entries for this problem all assume there are memory/disk space limitations, but I know this isn't the problem because the old (non-threaded) version runs fine, and Process Explorer tells me the threaded version isn't using any more memory.
Has anyone seen this error message before? Any suggestions what to look for to track down the cause of this error?
Thanks,
Alan

Have you seen this blog[^]. Could it help in your situation?

The cause of the problem is that apparently Win32 bitmap handles become STALE, i.e. they're for temporary use only.
This led to the problem showing up in different places, depending on when Windoze decided to make the handles invalid.
The solution was to pass bitmaps into the lower-level C# functions, then obtain the handles at the last possible moment, inside a loop, just before descending into Win32. These handles were fresh for each iteration, and worked perfectly.
I think the Win32 system should provide a less-misleading error message when a stale handle has been used. &*($! Microsoft!

OK i have made a DLL with only one accessible function. It returns a panel with a label in it.
In the dll there's also an event handler for mousemouve. It needs to change the label to display the mouse position on the panel.
My problem is that i need everything done on the side of the DLL. The main program is only there to place the panel on a form and must not deal with event handling from the panel.
here's what i got for the dll
namespace PanelClass
{
public class ConstPanel
{
public Panel FabPan(int x, int y)
{
Panel P = new Panel();
Label L = new Label();
L.Left = 1;
L.Top = 1;
L.Text = "allo";
P.Height = y;
P.Width = x;
P.BorderStyle = BorderStyle.FixedSingle;
P.Controls.Add(L);
P.MouseMove += new MouseEventHandler(P_MouseMove);
return P;
}
void P_MouseMove(object sender, MouseEventArgs e)
{
//needs to change the text in label L
}
}
}
and the main application
private void button1_Click(object sender, EventArgs e)
{
PanelClass.ConstPanel P = new ConstPanel();
Panel Pan = P.FabPan(100, 100,1);
this.Controls.Add(Pan);
}
So what should i do
thanks for your time
