  • Compressing a web service response for jQuery

    - by SirDemon
    I'm attempting to gzip a JSON response from an ASMX web service to be consumed on the client-side by jQuery. My web.config already has httpCompression set like so: (I'm using IIS 7) <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" staticCompressionDisableCpuUsage="90" staticCompressionEnableCpuUsage="60" dynamicCompressionDisableCpuUsage="80" dynamicCompressionEnableCpuUsage="50"> <dynamicTypes> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="text/css" enabled="true" /> <add mimeType="video/x-flv" enabled="true" /> <add mimeType="application/x-shockwave-flash" enabled="true" /> <add mimeType="text/javascript" enabled="true" /> <add mimeType="text/*" enabled="true" /> <add mimeType="application/json; charset=utf-8" enabled="true" /> </dynamicTypes> <staticTypes> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="text/css" enabled="true" /> <add mimeType="video/x-flv" enabled="true" /> <add mimeType="application/x-shockwave-flash" enabled="true" /> <add mimeType="text/javascript" enabled="true" /> <add mimeType="text/*" enabled="true" /> </staticTypes> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> </httpCompression> <urlCompression doDynamicCompression="true" doStaticCompression="true" /> Through fiddler I can see that normal aspx and other compressions work fine. However, the jQuery ajax request and response work as they should, only nothing gets compressed. What am I missing?

  • Looking for a simple interface for users to enter data for Silverlight application

    - by Edward Tanguay
    I have made a Silverlight application which can read data from various URLs. So users of the application who control a website can: FTP text and XML files onto their website put a clientaccesspolicy.xml in their root directory enter their URL in the silverlight application at which point the silverlight application then begins reading data from their site. I would like to extend this to less technical users who do not control a website, aren't adept with FTP, etc. What is the best service on the web that: allows users to publish different kinds of data, e.g. put out text files on web allows Silverlight client access (has clientaccesspolicy.xml set up) Some ideas are: free blog services (although then they are limited to a RSS feed, or the silverlight app would have to do some screen scraping) Google Docs? free cloud services? What free services allow easy publishing of any kind of data on the web and allow Silverlight client access?

  • LogonUser -> CreateProcessAsUser from a system service

    - by Josh K
    I've read all the posts on Stack Overflow about CreateProcessAsUser and there are very few resolved questions, so I'm not holding my breath on this one. But it seems like I'm definitely missing something, so it might be easy. The target OS is Windows XP. I have a service running as "Local System" from which I want to create a process running as a different user. For that user, I have the username and password, so LogonUser goes fine and I get a token for the user (in this case, an Administrator account.) I then try to use that token to call CreateProcessAsUser, but it fails because that token does not come with SeAssignPrimaryTokenPrivilege - however, it does have SeIncreaseQuotaPrivilege. (I used GetTokenInformation to dump all the privileges associated with that token.) According to the MSDN page for CreateProcessAsUser, you need both privileges in order to call CreateProcessAsUser successfully. It also says you don't need the SeAssignPrimaryTokenPrivilege if the token you pass in to CreateProcessAsUser() is a "restricted version of the calling process' primary token", which I can create with CreateRestrictedToken(), but then it will be associated with the Local System user and not the target user I'm trying to run the process as. So how would I create a logon token that is both a restricted version of the calling process' primary token, AND is associated with a different user? Thanks! Note that there is no need for user interaction in here - it's all unattended - so there's no need to do stuff like grabbing WINSTA0, etc.

    - by Arul Servin
    I need to copy and paste the data from one Excel spreadsheet to another based on column name. For example, one shreadsheet has columns named like Asset, Asset owner. Another spreadsheet has column named like Application, Application Owner. Now I want "Asset" column data to copy and paste into the "Application" column in another spreadsheet. The same way "Asset owner" column data should copy and paste into the "Application Owner" column in the other spreadsheet.

  • treeview loses data when page is being refreshed in asp.net

    - by Greg
    Hi, I have a treeview and I written a code for his "treeNodePopulate" event: protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["idList"] != null && e.Node.Depth == 0) { string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details TreeNode child = new TreeNode(""); // Go over all the yellow card details and populate the treeview for (int i = 1; i < words.Length; i++) { child.SelectAction = TreeNodeSelectAction.None; // Same yellow card if (words[i] != "*") { // End of details and start of point ip's if (words[i] == "$") { // Add the yellow card node TreeNode yellowCardNode = new TreeNode(child.Text); yellowCardNode.SelectAction = TreeNodeSelectAction.Expand; e.Node.ChildNodes.Add(yellowCardNode); child.Text = ""; } // yellow card details else { child.Text = child.Text + words[i] + " "; } } // End of yellow card else { child.PopulateOnDemand = false; child.SelectAction = TreeNodeSelectAction.None; // Populate the yellow card node e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(child); TreeNode moveChild = new TreeNode("Move To Reviewed"); moveChild.PopulateOnDemand = false; moveChild.SelectAction = TreeNodeSelectAction.Select; e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(moveChild); child = new TreeNode(""); } } Application["idList"] = null; } } I want the treenode to get the data from the Application variable and then nullify the Application variable so that the tree will take data from Applcation only if there is something in it (I put data into the application from another page and then redirect to this page) But when I refresh this page the data in the treenode isnt being saved. I mean after the refresh the Application is null so he isnt doing anything. The question is why is the data that I put in the treenode earlier isnt being saved? The "enableViewState" property is set to "true".. Thanks in advance, Greg

  • Error when trying to connect to Jacorb naming service

    - by Dopyiii
    I'm hoping to get some help with this weird problem. We're running the Jacorb name server and I have a simple client that I'm using to try to connect and do awesome CORBA voodoo. The name server is running, but when I try to start my java app, I get a "Connection failure" error (org.omg.CORBA.COMM_FAILURE, minor code 201, "caused by java.net.ConnectionException: Connection refused: connect"). Here's the weird part. The error reports that it's trying to connect using the default port 900, but I'm passing in an argument to try to override the port number of the name service to match the one being used by the name server. My java command is like this: java -classpath . HelloClient -Djava.endorsed.dirs="bla bla bla" -Dorg.omg.CORBA.ORBClass=org.jacorb.orb.ORB -Dorg.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton -DORBInitRef.NameService=corbaloc::localhost:2809/StandardNS/NameServer-POA/_root I also tried the parameters without the first capital D (I've seen it both ways and I don't know the difference). Now, if I put in -ORBInitialPort 2809, then the client does appear to try to connect, but then I get a corba.OBJECT_NOT_EXIST error. I could use any help or advise anyone has.

  • Qt Serial Port Errors - Data not getting read

    I'm trying to read a serial port with the Qt SerialPort library. I can read the data using HyperTerminal. In Qt I used the following code to try and do the same thing. Qt says the the port has been opened correctly, but for some reason, the bytesAvailable from the serial port is always 0. serial.setPortName("COM20"); if (serial.open(QIODevice::ReadOnly)) qDebug() << "Opened port " << endl; else qDebug() << "Unable to open port" << endl; serial.setDataBits(QSerialPort::Data8); serial.setParity(QSerialPort::EvenParity); serial.setBaudRate(QSerialPort::Baud115200); qDebug() << "Is open??

  • WinForms data binding with a Save button?

    - by Mat
    How is data binding in C# WinForms supposed to work when you have a Save button? I don't want the data updated until I press Save! I have two forms (list and detail) backed by a BindingList<T> collection and my custom object from that collection, respectively. I can bind each form to the list or object appropriately. However, any changes made in the detail form are immediately reflected in the list form - I don't want to save the changes and update the details shown in the list until the Save button is pressed. Is data binding designed to support this? Is there a common pattern for doing so? Whichever way I look at it, binding doesn't seem to be able to support this scenario. I've considered the following: Pass a clone of the object to the detail form, but then I have to reconcile the changes on Save - changes may have been made to the copy in the list in the meantime. Implementing IEditableObject and calling EndEdit on save almost works as I can prevent the list being notified of the changes made until Save is pressed, but if something else causes a refresh the list is updated with the interim data. I'm currently left with dispensing with data binding in my detail view, and doing it all manually. Which is rather annoying.

  • Is this good code? Linked List Stack Implementation

    - by Quik Tester
    I have used the following code for a stack implementation. The top keeps track of the topmost node of the stack. Now since top is a data member of the node function, each node created will have a top member, which ideally we wouldn't want. Firstly, is this good approach to coding? Secondly, will making top as static make it a better coding practice? Or should I have a global declaration of top? #include<iostream> using namespace std; class node { int data; node *top; node *link; public: node() { top=NULL; link=NULL; } void push(int x) { node *n=new node; n->data=x; n->link=top; top=n; cout<<"Pushed "<<n->data<<endl; } void pop() { node *n=new node; n=top; top=top->link; n->link=NULL; cout<<"Popped "<<n->data<<endl; delete n; } void print() { node *n=new node; n=top; while(n!=NULL) { cout<<n->data<<endl; n=n->link; } delete n; } }; int main() { node stack; stack.push(5); stack.push(7); stack.push(9); stack.pop(); stack.print(); } Any other suggestions welcome. I have also seen codes where there are two classes, where the second one has the top member. What about this? Thanks. :)

    So I've gotten a project and got the db team sold on source control for the db (weird right?) anyway, the db already exists, it is massive, and the application is very dependent on the data. The developers need up to three different flavors of the data to work against when writing SPROCs and so on. Obviously I could script out data inserts. But my question is what tools or strategies do you use to build a db from source control and populate it with multiple large sets of data?

  • Typecasting EnityObject

    - by AJ
    Hello, I'm new to C# and am stuck on the following. I have a Silverlight web service that uses LINQ to query a ADO.NET entity object. e.g.: [OperationContract] public List<Customer> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } This works fine, but what I want to do is to make this more abstract. The first step would be to return a List<EntityObject> but this gives a compiler error, e.g.: [OperationContract] public List<EntityObject> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } The error is: Error 1 Cannot implicitly convert type 'System.Collections.Generic.List<SilverlightTest.Web.Customer>' to 'System.Collections.Generic.IEnumerable<System.Data.Objects.DataClasses.EntityObject>'. An explicit conversion exists (are you missing a cast?) What am i doing wrong? Thanks, AJ

  • Database warehoue design: fact tables and dimension tables

    - by morpheous
    I am building a poor man's data warehouse using a RDBMS. I have identified the key 'attributes' to be recorded as: sex (true/false) demographic classification (A, B, C etc) place of birth date of birth weight (recorded daily): The fact that is being recorded My requirements are to be able to run 'OLAP' queries that allow me to: 'slice and dice' 'drill up/down' the data and generally, be able to view the data from different perspectives After reading up on this topic area, the general consensus seems to be that this is best implemented using dimension tables rather than normalized tables. Assuming that this assertion is true (i.e. the solution is best implemented using fact and dimension tables), I would like to see some help in the design of these tables. 'Natural' (or obvious) dimensions are: Date dimension Geographical location Which have hierarchical attributes. However, I am struggling with how to model the following fields: sex (true/false) demographic classification (A, B, C etc) The reason I am struggling with these fields is that: They have no obvious hierarchical attributes which will aid aggregation (AFAIA) - which suggest they should be in a fact table They are mostly static or very rarely change - which suggests they should be in a dimension table. Maybe the heuristic I am using above is too crude? I will give some examples on the type of analysis I would like to carryout on the data warehouse - hopefully that will clarify things further. I would like to aggregate and analyze the data by sex and demographic classification - e.g. answer questions like: How does male and female weights compare across different demographic classifications? Which demographic classification (male AND female), show the most increase in weight this quarter. etc. Can anyone clarify whether sex and demographic classification are part of the fact table, or whether they are (as I suspect) dimension tables.? Also assuming they are dimension tables, could someone elaborate on the table structures (i.e. the fields)? The 'obvious' schema: CREATE TABLE sex_type (is_male int); CREATE TABLE demographic_category (id int, name varchar(4)); may not be the correct one.
