Hi there,
I'm have a little problem with my page caching. On my admin side, I have a list of members. Lets say I want to update member Dean Martin, then I would click on his name and it takes me to an update page, I will change his last name to something like Martinn. The message displays that the member has been updated successfully. Then I have a link that goes back to the members listing, then it still displays as Dean Martin. I have to press CTRL + F5, then it will only update to Dean Martinn. I don't want to do this.
Each of my pages extend from a base page, and in the load up of this page is does the following:
this.Response.Buffer = true;<br />
this.Response.Expires = 5;<br />
this.Response.ExpiresAbsolute = DateTime.Now.AddMinutes(5);<br />
this.Response.ContentType = "text/html";<br />
this.Response.CacheControl = "private";<br />
this.Response.AddHeader("Pragma", "no-cache");<br />
this.Response.AddHeader("Cache-Control", "Private");<br />
Could this maybe be the problem? Am I doing it right or wrong? Can someone please help me with this problem that I am having??
Regards,
ma se

How would i go about creating a Parameter containing an object (TypeCode.Object) to pass to an update method of a ObjectDataSource.
When I create a new Parameter it won't allow me to set it's value to an object even though I set it's type to object.
Thanks in advance!

<br />
MyClass myClass = new MyClass;<br />
MyClass.Field1 = "A value";<br />
MyClass.Field2 = 2;<br />
MyClass.Field3 = false;<br />
ObjectDataSource1.UpdateParameters["myClass"] = myClass; <-- Will not accept this as a parameter value.<br />
Hope that makes some sense of what I'm trying to do

Hi
i am using following code to connect to ftp server on my own pc.
socket.Connect(endpoint);
then i m calling following code to read response.
noofbytes = clientSocket.Receive( buffer, buffer.Length, 0 );
when i m calling this sometimes, program hangs, it does not hang when i m debugging. so i have added System.Threading.Thread.Sleep(20) to sleep program, now its working, i want to know the reason program is hanging, and also i used 20 milliseconds after experiment. it may change on different machines.

Hi everyone,
I am doing a small project in asp.net which uses MySQL as back end.there is a field to store Hours in my table.I gave the datatype of double to that field.
Now I select the contents of the table and the resultant dataset will be bound to the datagrid as usual.
Here my double Hours field is truncating the trailing zeros.If total hour is 5.30 its showing as 5.3, but for 5.15 it shows 5.15 as correctly.how to fix this.
this may be silly ...but I need help from some one......
Thanks

Actually no data is lost. It's just a matter on how the data is formated when being output. Have a look here[^] to get an overview of what is possible with formatting.
Generally speaking you can format your double the way you want. In your example it should be something like:
double d = 5.3
Console.WriteLine(d.ToString());
Console.WriteLine(d.ToString("#.00"));
Console.WriteLine(d.ToString("00.00"));

I wanted to reset the record number on beginning of odd page numbers (Not applying to the page number 1) to immediate previous even page beginning record number. Ex. if page 2(even page number) starts with record number 1, then I wanted to reset the record number to 1 in the next odd page number (i.e. 3). Similarly if page 4(next even page number) starts with record number 26, then I wanted to reset the record number to 26 in the next odd page number (i.e. 5). This should continue through out the report. Is it possible do this?  Please comment on this.
Or anybody have any idea to display lengthy records (Which has several columns) runs up to 2 A4 papers in continuous order. Ex. Assume it show 25 records in the first page and remaining columns same 25 records in the next page. Then it should show the records from record number 26 at the next page. This should continue through out the report.
Thank you in advance.

Hi..
Crystal does have global variables for pagenumber, or force reset of pagenumber, and you probaly have to to do this check and reset on the page header or footer group.
.NET Rules

I tried that. But the record number is a read only value. Isn't it? So how to set a value to it even though the check can be done at the page header?

Hello everybody
I'm trying to scale down a image file, the thing is that I can't find anyway to do that without getting the image into a Grapgics object.
Using the graphics object to scale down is easy (using ScaleTransform()), the thing is that I want to convert back to Image in order to place the image in a picturebox.
can anyone help me with that???
Thanks in advance!

Instead of changing your instance you could create a new one:
Image oldImage;
Image newImage = new Bitmap(wantedWidth, wantedHeight);
using (Graphics g = Graphics.FromImage(newImage))
{
g.DrawImage(oldImage, 0, 0, wantedWidth, wantedHeight);
}

Say, I have this string ℵ, the hebrew Alef Symbol. In the charmap program it maps to the Unicode code point U+2135 (hex). However when I do a GetBytes on a string with alef in it, I get back a 3 byte representation: E2 84 B5.
I'm just confused on how to map this back into 21 35???? How does the hex E2 84 B5 relate to 21 35. Why does charmap say alef is 2 bytes, when UTF8Encoding.GetBytes says it's 3 bytes?
