Re: combining a Gif and a JPG into a file ...

You can't combine the files, you have to unpack them into images and combine them.

Load the JPG file into a BitMap object and the GIF file into another. Create a Graphics object for the first image and use that to draw the second image into the first. Save the result as a new image file.

The FromFile and Save method in the Image class and the FromImage and DrawImage methods in the Graphics class.

Standard question #1:
What do you mean by "not working"?

I have problem saving the contents of Graphics object to disc , can you show me the way ?

The Graphics object doesn't contain anything that you can save. You save the image that you have drawn on.

Hello,

im building a web application and although 90% of the users will be internal employees the other 10%
will be the customer.

Tying to keep user accounts in one place I didnt want to create a new sql database.
So I thought about usins AD as the Authentication.

Ive read in places that you should not use this for external users but the info was a bit grey I was wondering if anyone
can give me a low down on why I should not use AD.

Hi,

What are the possible syatax (usage) that we can able to give in the below symbol in the Design view of asp.net page?

<% %>

(eg) <%= .... %>

FYI, I wish to display all my data from DataSet. In my GridView, I am using the Dataset as a data source. So I wish to know the usage of <% %> in the Design view. I have googled for the all possible usage of <% %>. But its helpless for me.

Regards,

Jay Smile | :)

Don't know about DataSet, but if you use
DataView or DataTabel the syntax is

<br />
<%#DataBinder.Eval(Container.DataItem, "theColumnName").ToString()%><br />

I have experiensed that I have to use the <%=...%> sometimes

<br />
..table cellspacing="0" cellpadding="0" border="0" style="width:"<%=SomeStaticValue%>"..<br />

Re: <% %> usage in Design View asp.net

Unless you are using template columns in your gridview you don't need to use the databinding expressions.

Is there any reason why you aren't using the support provided by Dundas? They would seem to be the obvious place to ask that sort of question.

Exception with DataAdapter.Update ! [modified]

Hi,

I have an xml file with employee data and need to uplaod its content to the database.
For this I have used dataset.ReadXml method and then I am using the dataadapter.update method to upload the content of the dataset to the database.
Here is the code:
protected void Button1_Click(object sender, EventArgs e)
{

string path = @"D\emp.xml";
string dsTable = "";
string connectionString = @"Server = DB\SQL2; Database = CWBDB; user = sa; password = sa";
DataSet ds = new DataSet("EMPDS");
ds.ReadXml(path);
foreach (DataTable t in ds.Tables)
{
dsTable = t.ToString();
}
SqlConnection con = new SqlConnection(connectionString);
SqlDataAdapter da = new SqlDataAdapter();
da.TableMappings.Add("EMP", dsTable);
if ((da.Update(ds))>0)
{
Label1.Text = "Uploaded the data successfully";
}
else
{
Label1.Text = "Could not Upload the data";
}
}

But I see an exception:
"Update unable to find TableMapping['Table'] or DataTable 'Table'."

Please help!

da.TableMappings.Add("EMP", dsTable);
The above statement of my code makes a mapping between database table and dataset table, the first parameter is the database table name and the 2nd paramaeter is dataset table name. So I am getting the table name from the dataset and passing to it so that a mapping may occur between the database table and the dataset table.

In short I will explain what I am trying to do. Theres an xml file consisting of Employee data, I need to upload this xml content to the Database. For this I have used the Dataset.fill(xmlpath) and then using the dataadapter for updating the data to the database. Now u can see my previous code and get clear understanding.
