View 1 RepliesI have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = "";
static void OnClientConnected(string clientId, ref Dictionary<string, object> list)
{
list.Add("a", "b");
// I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:-
BaseController.clientId = clientId;
}
public ActionResult Handler()
{
if (something)
{
// use the static ClientId here
}
// Release the ClientId here, so it can now be used by other web requests coming to the server.
return View();
}
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.

Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
I'm having a little trouble with an upload of a file. I wanted to add today's date in the name of the file so that when a user uploads a file such as "image1.jpg" it would be saved into the server as "image120100319.jpg" and stored in the database as in a field as /myfolder/subfolder/image120100319.jpgthis script works when I comment the new additions which are
[Code]....
string SQL = "INSERT INTO my table (dailyFile) VALUES(@IMGDAILYFILE)";
cmd.Parameters.Add(new SqlParameter("@IMGDAILYFILE", SqlDbType.NVarChar, 80));
cmd.Parameters["@IMGDAILYFILE"].Value = "/myfolder/subfolder/" + destPath3.Substring(destPath3.LastIndexOf("\") + 1);

View 2 Repliesjust want to have a quick question about the value of dropdownlist listitem. I have a gridview which has its datakey value linked to a dropdownlist. In the dropdownlist I have many listitems. So I decided to combine some list items together. Originally, the values of the items are 1,2,3,4,5,6,7,8. But I want to have only 5 items by combining 5,6,7,8 into one listitem called "Others." So if the listitem "Others" is selected, the gridview will show all the records that have value 5 or 6 or 7 or 8. Is it possible? How can that be done?
I hope I made myself clear. Any question, I am happy to clarify.
If I have two two columns: Date1 and date2,I would like to display in GridView1 than one column.

I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

I have a report with several filter parameters. Everything works fine presently. For one parameter, I use the LIKE as follows in my WHERE statement:
WHERE drug LIKE '%' + @drugused + '%'
@drugused is the selection value of a dropdown list. But now I want to change my parameter to allow multi-selection. But I am not sure how to write my WHERE statement for this. Normally I would use IN but I'm not sure how to do this with the LIKE.
I'm preparing to pass values to a method:
private string BuildMessage(int templateID, string body, object data)
where the data param is an array of name/value pairs. To prepare my values for that data param I need to combine the properties of a strongly typed class with the values of a simple 2d array.
What's the best way to merge those values?
Is there a utility to combine querystrings? I'm looking for something like:
Input: Combine("test=a&test2=b", "test3=c") Result: "test=a&test2=b&test3=c"
Input: Combine("test=a&test2=b", "") Result: "test=a&test2=b"
Input: Combine("", "test3=c") Result: "test3=c"
And maybe some weird ones:
Input: Combine("&test=a&test2=b", "?test3=c") Result: "test=a&test2=b&test3=c"
Does anybody knows possibilities or approaches to combine ASP.NET with SAP Webdynpro (or to embed/integrate Webdynpro in a ASP.NET (or Silverlight) application) ?
View 2 RepliesI lied! The commandline fails if the two source files have different bitrates (does samplerate matter?). Also, the source code below succeeds when the two sources are the same bitrate. So, this looks like a bitrate challenge now.
Original question:
result.mp3 (from the commandline, below) is playable in WMP11. The ASP.NET code below serves a file which plays fine in WMP11. But, when I uncomment those two lines, WMP11 won't play the file. Something about the code that merges the two MP3 files isn't to the satisfaction of WMP11. How can I change the ASP.NET code to merge the two MP3s in the HTTP response with the success that the 'copy' commandline gives me?
protected void Page_Load(object sender, EventArgs e) {
Response.Clear();
Response.ContentType = "audio/mpeg";
Response.AddHeader("Content-Disposition", "attachment; filename=test.mp3");
var bytes1 = System.IO.File.ReadAllBytes(@"C: est1.mp3");
WriteBytesToResponse(bytes1);
//var bytes2 = System.IO.File.ReadAllBytes(@"C: est2.mp3");
//WriteBytesToResponse(bytes2);
Response.End();
}
private void WriteBytesToResponse(byte[] sourceBytes) {
using (var sourceStream = new MemoryStream(sourceBytes, false)) {
sourceStream.WriteTo(Response.OutputStream);
}
}
copy /B test1.mp3+test2.mp3 result.mp3
I have developed some ASP.NET server controls which include their own javascript and css files. A lot of these controls use jQuery extensions which, as you know, often include their own css files.
I'm using Telerik's RadScript manager which combines the javascript like a boss. However, I'm using the AjaxToolkit's ClientCssResource attribute to include the css files in my server controls, and I have noticed that the CSS files are not getting combined at all. My pages have 10-15 WebResource.axd requests for css files for my server controls.
Everything I find only is about combining javascript, and nothing tells me how I can combine the CSS files. Does anyone know if there is a way to combine the CSS dynamically (I don't want to manually combine as each page might use a different subset of the server controls)?
