Hi
Almost in all web sites in internet there is a propaganda at left or right top corner of the web site.
Now I want to Use propaganda in my site (VS2010 – C#). HOW CAN I DO IT?
Thanks very much
|
|
|
|
|
By propaganda you mean advertisements. There are many ways. Most sites use services such as adsense[^]. If you want to do it yourself there is the AdRotator[^] control available.

Hi
How can I Limit size of pictures for upload in my web site (VS2010 – C#)?
Thanks very much
|
|
|
|
|
You can find that information in a place we like to call, documentation[^]
"The default size limit is 4096 kilobytes (KB), or 4 megabytes (MB). You can allow larger files to be uploaded by setting the maxRequestLength attribute of the httpRuntime element."

suggest used JS, U'll know the file size befor U loadup.

Do you want to limit the size under a certain value?

Hi
I export my GrideView from asp.net to excel but the fields which contain Persian character don’t export finely (VS2010 – C#). HOW CAN I DO IT?
My code is :
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("content-disposition",
string.Format("attachment;filename={0}.xls", "Exported"));
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/ms-excel";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// Create a table to contain the grid
Table table = new Table();
foreach (GridViewRow row in GridView1.Rows)
{
table.Rows.Add(row);
}
// render the table into the htmlwriter
table.RenderControl(htw);
// render the htmlwriter into the response
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.End();
}
}
Thanks very much

Format your code snippets

if you want export fine,you used row[m][n],each other cell, you'll format fields to excel.

You don't export the GridView, you export the DataSource of the GridView.
Assuming you are using a DataTable as the DatSource
StringBuilder sb = new StringBuilder();
List<string> rows = new List<string>();
foreach(DataColumn col in DataSource.Columns)
{
rows.Add(col.ColumnName);
}
sb.AppendLine(string.Join(",", rows.ToArray()));
rows.Clear();
foreach(DataRow row in DataSource.Rows)
{
foreach(object item in row.ItemArray)
{
rows.Add(item.ToString());
}
sb.AppendLine(string.Join(",", rows.ToArray()));
rows.Clear();
}
Response.ContentType = "Application/x-msexcel";
Response.AddHeader("content-disposition", "attachment;filename=export.csv");
Response.Clear();
using(StreamWriter writer = new StreamWriter(Response.OutputStream, Encoding.UTF8))
{
writer.Write(sb.ToString());
}
Response.End();
Failure is not an option; it's the default selection.

Each time you fetch your 15 records, you have to do some clean-up, or exit the function completely for the garbage collector to free memory in the heap.
So you must of used the new word some where, and your not destroying the object when done, or the 15 records are huge in size, like binding 100,000 records to a drop down box.

Is the exception being thrown on the dev box or a server?
It would help if you posted some code.
Maybe it's just that (out of memory) if you're in your dev box and have lots of things open (like visual studio) and the dev box has not a lot of resources.
Also, call GC.Collect() and verify if you still get the problem.

Out of memory exceptions are usually down to recursion - are you running a loop to process? Perhaps you're not incrementing a loop counter and it's processing the first record over and over...
C# has already designed away most of the tedium of C++.
