Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.

>>>How to use javascript function in aspx file?



I have a file util.js and there some funtions in same file.

For example functions name are keyUp, keyDown, isNumeric, isAlphaNumeric

I have used these functions in aspx code behind in a textbox to restrict user that he may not be able to input any special character.

Before, I used the code directly in aspx file but I have do it for different textboxes therefore to avoid much coding in aspx file I created util.js and put all code in this file but how to use these particular functions in aspx file I couldn't find the way.

Anyone have idea. Do share with me.

I used the reference like this:


' Font-Names="Verdana" Font-Size="8pt" Onkeyup= "keyUp(event.keyCode)" Onkeydown="return isAlphaNumeric(event.keyCode);" onpaste="return false;">

why I can not upload file to web by using WebClient.UploadFile method?



I am using WebClient.UploadFile method to upload a file to a web page.

The code is like this:

WebClient client = new WebClient(); 
byte[] responseBinary = client.UploadFile(url, fileName); 
string response = Encoding.UTF8.GetString(responseBinary);

But I can not upload it to server.

I used fiddler to see what happens, and it shows me the following information:

http status code: 302, request headers: POST /testing/upload/default.aspx HTTP/1.1

http status code: 302, request headers: GET /testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

http status code: 200, request headers: GET /(X(1)S(22pynhvxd3eqsb455pudx145))/testing/upload/default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1

I would like to know, why I get 302 code, and why it redirect me to the strange url with (X(1)S(22pynhvxd3eqsb455pudx145)) ?

By the way, the web page is ok to upload file by using web explorer.

calling a web service on a remote server from an ASPX page

hi, I want to call a web service on a remote server. I've done "add web reference" in my project, and VS2005 has created the .discomap and .WSDL in the App_Web_Reference folder. When I try add the namespace representing the web server (the name I created when I added the web reference) by "using XXXXX;" the code does not compile because XXXXX is not defined. Have I missed any steps? thanks, -me

calling a web service on a remote server from a ASPX page (web site project VS2005)

HI,I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder.  When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for  the new web service i'm trying to call. Have I missed any steps?Thanks in advance.-me

Method/Way to know whether a input path of FilesSystem contains any Child file/folder or not

Hi,I am looking for a Method/Way to know whether a input path of FilesSystem contains any Child file/folder or not. To know it currently I am using "Directory.GetFileSystemEntries(Path).Count" and checking if count > 0 then returning True else False. For this first method calculates all the files and folder and then return status to me but I want to exit out as soon as my method gets first element(file/folder) in specified path. Because above method is timing out when my input path contains more than 1 million files. I just need to check whether input folder path contains any child file/folder or not. I have tried to use Win32 API also but on ther server it is crashing so I donot want to use that solution. In .NET any method or way is present to know it. Please suggest me.

Usercontrol, in master page, calling a method on the main page?

I have user control called 'Header.asxc' that is registered in my master page. That user control has an image link. The clicking of this link needs to cause a dropdown on the main page to repopulate. I am comforable with delegatges, with populating the dropdown etc... My problem is I cant find the usercontrol from the page, in order to set the function event. I got this work previously when the user control was registered on the page in question but this case with the master page  has me confused. Here is a summary of the set up. 1. I put this in the Header.ascx usercontrol that is registered by the Master page. public Delegate locReloadCompanyDropdown;2. Further down in that page in the relevent _Click event, I put this. locReloadCompanyDropdown.DynamicInvoke();3. Back in the main page I declared these.. public delegate void reloadCompanies(); private event reloadCompanies doReloadCompanies;4. Finally I try to set the delegate doReloadCompanies += new reloadCompanies(PopulateCompanyDropdown); //Page.Header.locReloadCompanyDropdown = doReloadCompanies; //Header.locReloadCompanyDropdown = doReloadCompanies;You can see a couple of attempts I have made remarked out in the code above. Neither work. What am I missing here? Thanks all.  

How to set and map a Method in the Service file with endpoint elements and binding elements

Hi all, I have created a service file like OSService.svc in that i have two methods like one is FileUpload and FileDownload for e.g :- [WebInvoke(UriTemplate = "/fileupload/{fileName}" , Method = "POST" )]         [OperationContract]         void FileUpload(string fileName, Stream fileContents); same as Filedownload also. People you may know these methods are inside the interface of service file what you are using i'e i have created a interface as IOSService.cs. So, what i need now is i want to write separate endpoint for FileUpload and Filedownload.Because i want to set separate value for receiveTimeout  and openTimeout for the Fileupload and FileDownload process in binding section in the web.config file itself. The below code was i'm using right now but still i'm not able to the set separate value of endpoint elements in the bindings. EndPoint Section:- <endpoint name = "endPoint1"  address  = "localhost:8000/OSService.svc/" bindingConfiguration = "TransactionalTCP"   binding  = "netTcpBinding"          contract = "IOSService"/> Binding Section:-  <binding name = "TransactionalTCP"  transactionFlow = "true"   /&

Memory Management issue while calling COM method from .Net component

Hi all,  The Com Component Method say(GetChildresponse) requires Byte pointer as input. From .Net Component, while calling GetChildResponse  I am creating IntPtr and passing it to Component.  I am only creating the pointer in my .Net Component but allocation of bytes(CoTaskMemAlloc) happens at COM Method. After populating the pointer buffer, I am transferring to memory buffer in .Net method and Free the memorry of the pointer using "Marshal.FreeCoTaskMem" method.  Still I am not sure, whether it is deallocating the memory since the Garbarge collector wont happen immediately.  We are hitting on performance issue while doing load testing and we suspect this might be due to memory allocation that is not getting deallocated properly. Any pointers would be helpful. Thanks, Nithya Sample Code: unsafe {   // Get the physical memory address ocpHeaderBufferPointer = new IntPtr((void*)&ocpHeaderBufferPointer); temporaryResponseBufferPointer = new IntPtr((void*)&temporaryResponseBufferPointer); }   try {   try {   // Call the GetResponse of the pass through ocpChannel   new OCPChannelDSClass().GetResponse((uint)transactionId, ocpHeaderBufferPointer, out ocpHeaderBufferSize, temporaryResponseBufferPointer, out temporaryResponseBufferSize, (uint)timeout); }   catch (Exception ex) { &nbs

Linking JS file to ASPX page or content page

Hi, I moved my JS functions into an external file "JScript.js", because I'm now using a master page and a content page.But it doesn't work any more, and I can't find why.I tried simply to link a js file to an ASPX file, by adding to the script manager the path of my script, but it doesn't work.Here is my js file (we don't need any special things in it do we?) var step1 = false; function pageLoad() { var accCtrl = $find('AccordionCtrl_AccordionExtender'); accCtrl.add_selectedIndexChanged(onAccordionPaneChanged); } function hideAccordionPane(paneNo) { ... } function changeSelected(idx) { ... } function onAccordionPaneChanged(sender, eventArgs) { ... } function check() { ... }And here is my ASP code: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

Calling a method with a class object as parameter data type.

   [WebMethod]    public string GetInfo(Customer inCust)    {        // Code in here    } I have a web service that resides on a remote server. I want to call a public method of theweb service named  "GetInfo". The method is shown above. The web service method expects a class object oftype "Customer". What I did to create a Customer object was to define in my asp.net project my own class named "Customer" which is exactlythe same as the class that belongs to the web service project on the remote server. I then created an instance of Customerand tried to call the web service passing in an object of type customer : my.Service ws = new my.Service(); // Get web service connectionCustomer aCustomer = new Customer();aCustomer.Initialize();ws.GetInfo(aCustomer) // call web service passing in a Customer object The problem is that the compiler gives me the following error: Value of type '_Default.Customer' cannot be converted to 'ws.Class1'. Here Default is refering to my Default.aspx.cs code. Why is this? Do I need to Cast my "aCustomer" class object to a type ofws.Customer ? How do I do that?
