is it possible to have a link/button/etc that when clicked creates a CVS from a dataset (that bit i can do) then presents it as a download without having to write the file to the server?
So basicly when they click the link/button it streams the data from the dataset into a text file that is being downloaded.
Thanks

Hi,
i have a table with an INT column. The value is either 0 or 1. (It is a flag).
Now i'd like to bind it to an checkbox. 1 for checked. 0 for unchecked.
I tried this:
<asp:CheckBox ID="chkOutIn2" runat="server" Checked='<%# Bind("flag_out") %>' Text="Out" />
But i get an exception.
How do i get this checkbox checked?
(The update is no problem, i can convert the bool i get)
Thank you.

Try to do it on DataBinding event of Check box.
Hopefully it will work.

How to store data from one table to another table in different databases using webservices?
|
|
|
|
|
In .net fetch data in a DataSet and from your web service return this DataSet.
then you can use this DataSet.
for example using asp.net i created a webservice which is fetching data from Sql server then
I am passing this data to mysql server.
Do not hesitate for further question.

hi guys,
i'm using asp.net to build web application.
how can i store image in sql server express edition, and display it
at the web.
|
|
|
|
|
Store an image, or any binary information in a varbinary(max) column. In order to store or retrieve it you must use a byte[]. In order to display it you can create a special ASPX that overrides the existing render process and writes out binary information instead.
|
|
|
|
|
hi,
i new to asp.net
i still cant understand about "create a special ASPX that overrides the existing render
process"....
can you pliz show me just VERY VERY simple example on how to display the image.
|
|
|
|
|
Create an aspx page, remove all markup except the @Page tag, and use BinaryWrite to output the image data:
int id = int.Parse(Request.QueryString["id"]);
byte[] imageData = YourDataBaseCallToGetImageData(id);
Response.ContentType = "image/jpeg";
Response.BinaryWrite(imageData);
Put the address of the page as src in an image tag:
<img src="ShowImage.aspx?id=42">

Seriously, you'll have to be more specific. You might also want to read up on Design Patterns.

You can use a regular expression that matches text in apostrophes. Use the pattern "'(.*?)'".
