your hopes are answered... you are wrong Big Grin | :-D

see the post i left for the OP for some interesting links... at first i assumed the same as you and thought WMP just linked the files with the images as in a lot of instances i always see album art as a seperate image file. though i suppose in the instance of 'album' art it is more practical to store the image once if it is to be used by multiple tracks, rather then embedding the same image in every track on the album

So you want to fill the listview in reverse order, making the last read item the top-item in the listview?

Or do you just want to scroll to the top when the loading is done?

i want it to scroll continously from bottom to top when d form is being loaded !!!

Eddy Vluggen14-Apr-09 6:27

14-Apr-09 6:27

If I understood correctly now, you want to load a record, add it to the bottom of the list, and scroll up? Load your list in the reverse order as now, inserting items at the top of the listview instead of the bottom Smile | :)

That might slow down loading though, since it will wait for a repaint before loading the next one.

ohhkk....
Wat if i display d values in d form of labels. Then can i scroll / move the labels from bottom to top continously !!!

Eddy Vluggen14-Apr-09 22:39

14-Apr-09 22:39

Yeah, but then you'd have to position these labels, whereas a listview has built-in functionality for that.

Response Headers

Hi all,

Is there a way that i can use inline and attachment at the same time in content-disposition for Response Headers?

i have code like this

HttpContext.Current.Response.AddHeader("Content-disposition", "inline; filename=__aaa.pdf");

I want to open the file first in the browser and then open the dialog box for download as well.
How can i do that?
I tried to AddHeader again after that line of code and replaced the "inline" with "attachment", but that didn't work.

Please help me.

Thanks alot!

Saving exported Excel doc generates missing CSS file error

14-Apr-09 1:18

Make two pages out of it; use the first page to display it, the second page to download it. Next, embed the first page into page two (using a frame?) Smile | :)

Re: Um, NewLine char ain't workin' nomore.

13-Apr-09 23:07

Hi all,

I'm using \n to create a new line when I wrote to a text file. Here's how I'm writing the string:

File.AppendAllText(destinationpath.Text, "Hi, this is a\n multiline\n text\n file.");

Now, it's not working.When I open the text file that was created, the whole thing's just a single line, but where the new line should have been created, there is a weird-looking square in its place. I've used \n to create new lines in the past and it worked perfectly but it doesn't want to work anymore. Does anyone have any ideas?

Jay.

newlines are actually carrige return + linefeed. which for you is \r\n or use Environment.Newline as suggested above.

Hey all!

,

I'm not expecting any replies but I'd appreciate them. I'm trying to figure out how I would go about capturing a link-click in internet explorer. What I want to do is when I click on a download link for example I click link on say www.download.com to download a program and instead of having the internet explorer download window appear, my program will become visible and download the file relating to that link I clicked on. I have tried searching for this on Google and haven't found anything but I'm sure it's just how I'm searching for it, I've run out of search phrases lol.

Regards,
Jay.

Hi all,

I converted a number from a TextBox and a problem happened.
TextBox.Text = "616753008";
After converting to a float the value is 6.16753E+8. (I debug in code)
And then this number is saved into DB is 616753024

I do not know what happen.
Pls tell me how I can solve this problem.

Thanks in advance.

6.16753E+8 is equal to 616753024

its the same, well almost, the first is less precise

EDIT: sorry i missed what your problem was... what about trying to convert to a double instead of a float

objStockCard.Pump is float;
objStockCard.Pump = Convert.ToSingle(txtPrice.Text);

So I use Convert.ToSingle (Convert.ToDouble is exact but complier does not accept set a double variable to a float variable).

Pls tell me how I can do now. I do not want to change objStockCard.Pump type.

Thanks for your reply.
