View 5 RepliesI have finished developing an executable desktop application to generate a fractal image based on the passed-in arguments. The output type is JPEG.Now I am developing a site under ASP.NET MVC 3. I want to use the executable from within my site.

Is it possible to invoke setup file in asp.net web application? for example, run the web application (like [URL], select the setup file and upload to server and invoke it(from the server setup will be executed), user enter the required details and install it, after installation completed site will be refereshed.
Note: I think not possible to use process.start method, because error will be produced in IIS (after hosting in IIS). from the development point its working (run the code using VS2010).
I am using c# and ASP.NET 2.0.

[WebMethod(Description = "Adds two numbers", MessageName = "AddMessage")]
public string Add(string x)
{

string fileLoc = @"D:KumareshCreateFile.xml";

I deployed my webservice in IIS server. I have created another .net application, and called the webservice method from the new application. My problem is I am unable to redirect to the specified link[google.co.in]. I am getting the following error: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Web.HttpException: Response is not available in this context. at System.Web.UI.Page.get_Response() Sometimes I get the error as: "Object moved here".

View 1 RepliesI have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.
In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.
I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

View 2 RepliesASP.net can't update page from event handler
and it's been answered! My only problem is I don't really understand the solution. How does one Invoke the control when setting the property.
I have a label control but there doesn't seem to be an Invoke property/method on it.
I tried this...
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(Label1);
PropertyDescriptor myProperty = properties.Find("Text", false);
myProperty.SetValue(Label1, "my value");
but that seemed to be the same as
label1.text = "my value"
which didn't work
On my local machine with the default ASP web server I am able to browse my web service's methods, which have with prompts and an invoke button.But when I deploy this same code to an IIS server and I browse the asmx page I just get a descritpion of the methods.
The web server is running windows 7 and IIS 6.
for example, you are caching data within your ASP.NET web app that isn't often updated. You have another process running outside of the app which ocassionally updates this data, when you do this you would like the cached data to be cleared immediately so that the next request picks up the new data straight away.The caching service is running in the context of your web app and not externally - what is a good method of calling into the web app to get it to update the cache?
You could of course, just hack a page or web service together called ClearTheCache that does it. This can then be called by your other process. Of course you don't want this process to be externally useable or visible on your web app, so perhaps you could then check that incoming requests to this page are calling localhost, if not throw a 404. Is this acceptable? Could this be spoofed at all (for instance if you used HttpApplication.Request.Url.Host)?
I can think of many different ways to go about this, mainly revolving around creating a page or web service and limiting requests to it somehow, but I'm not sure any are particularly elegant. Neither do I like the idea of the web app routinely polling out to another service to check if it needs to execute something, I'd really like a PUSH solution.Note: The caching scenario is just an example, I could use out-of-process caching here if needed. The question is really concentrating on invoking code, for any given reason, within a web app externally but in a controlled context.
I have a asp.net input box:
<asp:TextBox ID="InCL" runat="server" Text=""></asp:TextBox>
As soon as a number is entered I would like to send that value to a javascript function that updates a Google gauge.
For example, user inputs 77, the google gauge immediately dynamically moves to that position.

View 4 RepliesI've a web services wich can invoke a pc on the internet when a new event has come.
How do I write the code?
I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an asp.net thread.

I have to fullfill a requirement where my activeX control (developed in c#) need to invoke a callback JavaScript function asynchronously (or) synchronously (or) in both ways. I can handle the context using threads. JavaScript:
function handler_1(){ ..... }
myActiveXObject.registerCallBack(handler_1);
Where in ActiveX control, I need a function "registerCallBack" to accept the argument. But I have no clue how to invoke that registered JavaScript function from my ActiveX control. By digging MSDN forum, I found something as script.GetType().InvokeMember("myJSFunctionName", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public, null, script, null);
the above line throwing me an exception Unknown Name etc. I do have the definition for "myJSFunctionName" in javascript and I got the script object from the document object.
in have button inside updatepanel
when button this clicked, it do some thing and finally invoke another Button by Javascript by ServerSide as Follow:
protected void Buttton1_Click......
{
doSomeThing();
InvokeRemoteButton();
}
public void InvokeRemoteButton()
{
some thing like this
string phrse="<script type ...........etc............. Button1.click()........etc...</script>";
}
this is work when button outside update panel , but when i put it inside update panel , the Button Event will not fire !
In code-behind I can do this to select something:
// Select item in first DropDownList
myCascadingDropDown_1.SelectedValue = itemValue_1+":::"+itemText_1;
// Select item in second DropDownList
myCascadingDropDown_2.SelectedValue = itemValue_2+":::"+itemText_2;
How can I do this in JavaScript?
EDIT:
I can select my desired item in the first dropdownlist. The problem is however, that new values based on that selected item (it is a CascadingDropDown, remember?) don't show in the second dropdown so I can't select anything there. I would need to somehow invoke the update method of the second dropdown manually.
I would like to call the click event of the the AsyncFileUpload control programmatically, is it possible?
