• HttpPostedFile.SaveAs() throws UnauthorizedAccessException even though the file is saved?

  - by jrummell

  I have an aspx page with multiple FileUpload controls and one Upload button. In the click handler I save the files like this: string path = "..."; for (int i = 0; i < Request.Files.Count - 1; i++) { HttpPostedFile file = Request.Files[i]; string fileName = Path.GetFileName(file.FileName); string saveAsPath = Path.Combine(path, fileName); file.SaveAs(saveAsPath); } When file.SaveAs() is called, it throws: System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.UnauthorizedAccessException: Access to the path '...' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode) at System.Web.HttpPostedFile.SaveAs(String filename) at Belden.Web.Intranet.Iso.Complaints.AttachmentUploader.btnUpload_Click(Object sender, EventArgs e) at System.Web.UI.WebControls.Button.OnClick(EventArgs e) at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.departments_iso_complaints_uploadfiles_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Now here's the fun part.

• Serialize Forms into memory

  - by serhio

  Background: In a desktop MDI application we have a lot of forms. Task: Save the controls contents of closed forms(textbox texts, checkbox checks etc). Limitations: A saved form for (DB/Windows) user? For (DB/Windows) group of users? Both variants may be possible. Question: a) What is the best way? b) if I want do not use files, how to serialize the form into a MemoryStream and then recuperate it if the opening form was been once opened and serialized? StartingPoint: Implemented a form that implements ISerializable. Deserialize the form on opening, serialize onclosing: Public Sub GetObjectData(ByVal info As System.Runtime.Serialization.SerializationInfo, ByVal context As System.Runtime.Serialization.StreamingContext) Implements System.Runtime.Serialization.ISerializable.GetObjectData info.AddValue("tbxExportFolder", tbxExportFolder.Text, GetType(String)) info.AddValue("cbxCheckAliasUnicity", cbxCheckAliasUnicity.Checked, GetType(Boolean)) End Sub Public Sub New(ByVal info As SerializationInfo, ByVal context As StreamingContext) Me.New() Me.tbxExportFolder.Text = info.GetString("tbxExportFolder") Me.cbxCheckAliasUnicity.Checked = info.GetBoolean("cbxCheckAliasUnicity") End Sub Private Sub SerializeMe() Dim binFormatter As New Formatters.Binary.BinaryFormatter Dim fileStream As New FileStream(SerializedFilename, FileMode.Create) Try binFormatter.Serialize(fileStream, Me) Catch Throw Finally fileStream.Close() End Try End Sub Protected Overrides Sub OnClosing(ByVal e As System.ComponentModel.CancelEventArgs) SerializeMe() MyBase.OnClosing(e) End Sub

• How do you detect when the Flowplayer has started playing the video?

  - by Alex

  Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

• Set "Start With" value for Oracle sequence dynamically

  - by Allan

  I'm trying to create a release script that can be deployed on multiple databases, but where the data can be merged back together at a later date. The obvious way to handle this is to set the sequence numbers for production data sufficiently high in subsequent deployments to prevent collisions. The problem is in coming up with a release script that will accept the environment number and set the "Start With" value of the sequences appropriately. Ideally, I'd like to use something like this: ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] CREATE SEQUENCE seq1 START WITH &EnvironNum*100000; --[more scripting] This doesn't work because you can't evaluate a numeric expression in DDL. Another option is to create the sequences using dynamic SQL via PL/SQL. ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] EXEC execute immediate 'CREATE SEQUENCE seq1 START WITH ' || &EnvironNum*100000; --[more scripting] However, I'd prefer to avoid this solution as I generally try to avoid issuing DDL in PL/SQL. Finally, the third option I've come up with is simply to accept the Start With value as a substitution variable, instead of the environment number. Does anyone have a better thought on how to go about this?

• Displaying windows-1252 text in a literal control

  - by GordonB

  I currently have an aspx page that has a placeholder on it. In the code-behind page i'm adding a literal control to the placeholder controls collection. The literal control just contains text/html read from a sql server database field. The only text character encoding i've used so far is UTF-8. I have the requirement for a specific page to use windows-1252 encoding. I've strapped this to the page, and browsers now recognise the proper encoding. <% Response.Charset= "windows-1252" %> My issue is that i have various german characters ( ö / ü / etc ) that aren't displaying correctly. As presumably they are still be written to the page in UTF-8 not in windows-1252. I'm looking at; Dim textEncoder = System.Text.Encoding.GetEncoding(1252) Which seems to be more geared up to dealing with byte arrays than text. Do i have to change my text to a byte array then encode as windows-1252 then get the text back out again, or is there a simpler way of achieving what i'm after?

• Suggest the way to design several classes

  - by Oleg Tarasenko

  Hi, I'm building simple application on as3. Kind of starship game. What I want to do is to create several different star ships. Each one should have different images (different look), different sets of animation (e.g. when it's flying, burning, damaged), different kind of weapon and also different controllers (e.g. one can be managed by user, another one by computer, and I want to be able to reuse same ships for AI controller as well as for users controls). Each ship is created in the following way: Create entity Add spatial Add renderers Add other components.... ...... n. init the ship So what I am trying to do: 1) Create StarShip superclass, to store HP (as every ship has it), store spatial (same reason) 2) Create inherited class for any other ship... (It will contain renderer - (responsible for display part), weapon, set of animations), etc What do you think about such way of composition? Maybe it's better to place everything in super class, and then just create instances using long, long, long constructors like: StarShip(hp:HP, animations:DICT, weapon:Weapon, ....) Need advice

• Ember nested route. Load more models

  - by user3568719

  JsBin http://jsbin.com/EveQOke/153/ I know how to load more then one model to a route, using Ember.RSVP.hash. (see Jsbin Children menu). I use dynamic part to access one elem from a collection children/1. But i cant load more models to a nested resource. In my example i want to populate all the toys for a select, not just list the toys of the child. I have tried to access the model of the route children App.ChildRoute = Ember.Route.extend({ model: function(param){ return Ember.RSVP.hash({ allToys: this.modelFor("children"), child:this.store.find('child', param.child_id) }); } }); and use its model's toy property (since there have already loaded all of the toys) child.hbs <h4>All avaiable toys</h4> <table> {{#each toy in model.allToys.toys}} <tr> <td>{{toy.name}}</td> </tr> {{/each}} </table>

• Php/Regex get the contents between a set of double quotes

  - by Davy Arnold

  Update to my question: My goal overall is to split the string into 4 parts that I can access later. value = " result of the html inside the first and last " " Here is an example of what i'm trying to do: // My string (this is dynamic and will change, this is just an example) $string = 'value="<p>Some text</p> <a href="#">linky</a>"'; // Run the match and spit out the results preg_match_all('/([^"]*)(?:\s*=\s*(\042|\047))([^"]*)/is', $string , $results); // Here is the array I want to end up with Array ( [0] => Array ( [0] => value="<p>Some text</p><a href="#">linky</a>" ) [1] => Array ( [0] => value ) [2] => Array ( [0] => " ) [3] => Array ( [0] => <p>Some text</p><a href="#">linky</a> ) ) Basically the double quotes on the link are causing me some trouble so my first though was to do [^"]$ or something to have it just run until the last double quote, but that isn't getting me anywhere. Another idea I had was maybe process the string in PHP to strip out any inner quotes, but i'm not sure ho to go about this either. Hopefully I'm being clear, it is pretty late and i've been at this far too long!

• User control loosing its contents when loaded programatically

  - by Phil

  I have a usercontrol which contains 2 repeaters and the code to populate them with data. If i manually insert this into the page then it works correctly, the repeaters populate etc. If I load it programatically using this method; 1) add class name to user control ClassName="ContentModule" 2) reference this in the default.aspx <%@ Reference Control="~/modules/content.ascx" %> 3) Add the code to my codebehind page_load to do the loading; Private loadmodule As ASP.ContentModule Try If themodule = "content" Then loadmodule = CType(LoadControl("~\Modules\Content.ascx"), ASP.ContentModule) Modulecontainer.Controls.Add(loadmodule) End If Catch ex As Exception Response.Write(ex.ToString & "<br />") End Try Nothing from within the usercontrol is loaded to the page. Although if I add some static text i.e "TEST" to the top of the usercontrol this is displayed ok on the default.aspx page. This makes me think that the control is loaded ok, but there is something in the way I have loaded it that is causing the contents to not properly execute. Very frustrating this one! Any help greatly appreciated!

• how can a Win32 App plugin load its DLL in its own directory

  - by Jean-Denis Muys

  My code is a plugin for a specific Application, written in C++ using Visual Studio 8. It uses two DLL from an external provider. Unfortunately, my plugin fails to start because the DLLs are not found (I put them in the same directory as the plugin itself). When I manually move or copy the DLLs to the host application directory, then the plugin loads fine. This moving was deemed unacceptably cumbersome for the end user, and I am looking for a way for my plugin to load its DLLs transparently. What can I do? Relevant details: the host Application plugins are located in a directory mandated by the host application. That directory is not in the DLL search path and I don't control it. The plugin is itself packaged as a subdirectory of the plugin directory, holding the plugin code itself, but also any resource associated with the plugin (eg images, configuration files…). I control what's inside that subdirectory, called a "bundle", but not where it's located. the common plugin installation idiom for that App is for the end user to copy the plugin bundle to the plugin directory. This plugin is a port from the Macintosh version of the plugin. On the Mac there is no issue because each binary contains its own dynamic library search path, which I set as I needed to for my plugin binary. To set that on the Mac simply involves a project setting in the Xcode IDE. This is why I would hope for something similar in Visual Studio, but I could not find anything relevant. Moreover, Visual Studio's help was anything but, and neither was Google. A possible workaround would be for my code to explicitly tell Windows where to find the DLL, but I don't know how, and in any case, since my code is not even started, it hasn't got the opportunity to do so. As a Mac developer, I realize that I may be asking for something very elementary. If such is the case, I apologize, but I have run out of hair to pull out.

• How can I strip Python logging calls without commenting them out?

  - by cdleary

  Today I was thinking about a Python project I wrote about a year back where I used logging pretty extensively. I remember having to comment out a lot of logging calls in inner-loop-like scenarios (the 90% code) because of the overhead (hotshot indicated it was one of my biggest bottlenecks). I wonder now if there's some canonical way to programmatically strip out logging calls in Python applications without commenting and uncommenting all the time. I'd think you could use inspection/recompilation or bytecode manipulation to do something like this and target only the code objects that are causing bottlenecks. This way, you could add a manipulator as a post-compilation step and use a centralized configuration file, like so: [Leave ERROR and above] my_module.SomeClass.method_with_lots_of_warn_calls [Leave WARN and above] my_module.SomeOtherClass.method_with_lots_of_info_calls [Leave INFO and above] my_module.SomeWeirdClass.method_with_lots_of_debug_calls Of course, you'd want to use it sparingly and probably with per-function granularity -- only for code objects that have shown logging to be a bottleneck. Anybody know of anything like this? Note: There are a few things that make this more difficult to do in a performant manner because of dynamic typing and late binding. For example, any calls to a method named debug may have to be wrapped with an if not isinstance(log, Logger). In any case, I'm assuming all of the minor details can be overcome, either by a gentleman's agreement or some run-time checking. :-)

• How to use google maps API with multiple markers on the same map

  - by Maen

  So, i have the following script to use the google maps API, its all fine, but i need to create a map that has more than one Marker (the balloon shaped icon pointing to something) and i need each of those markers to point on a different area of the map (i.e. different coordinates), how can i do it? <script type="text/javascript"> function load() { var map = new GMap2(document.getElementById("map")); var marker = new GMarker(new GLatLng(<%=coordinates%>)); var html="<img src='simplemap_logo.jpg' width='20' height='20'/> " + "<%=maptitle%><br/>" + "<%=text%>"; map.setCenter(new GLatLng(<%=coordinates%>), <%=zoom%>) map.setMapType(G_HYBRID_MAP); map.addOverlay(marker); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); marker.openInfoWindowHtml(html); } //]]> </script> One more question, if i pass the Script text as a variable, lets say something like: <script type="text/javascript"> <%=ScriptText%> </script> and my <%=ScriptText% will be a string which i will build and assign its value to a Friend or Public variable called ScriptText, will it still run and work properly? (i am doing this to make my script dynamic and different based on how i build it as a STRING, due to my illiteracy in javascripting ;P)

• Which technology should I use to pop up a simple form in my add-in DLL?

  - by Decker

  I'm building an assembly that runs as an "add-on" to a vendor's Outlook add-in. When it is time for me to execute my "action", I have to put up a simple window with a few simple controls. The vendor's add-in provides me with the parent window's integer handle. I am able to put up a form pretty easily with WinForms by adding are reference to System.Windows.Forms from my assembly and with the following code: FrmHistoryDisplay frm = new FrmHistoryDisplay(); frm.ShowDialog(new ParentWindowWrapper(_parentWindowHandle)); where ParentWindowWrapper is a shim class around the window handle I'm given private class ParentWindowWrapper : IWin32Window { private int _parentWindowHandle; public ParentWindowWrapper(int parentWindowHandle) { _parentWindowHandle = parentWindowHandle; } public IntPtr Handle { get { return new IntPtr(_parentWindowHandle); } } } The Form's ShowDialog method takes an IWin32Window implementor to wrap the parent's window handle. This all works and seems simple enough. I was just wondering whether something similar can be done with a WPF window rather than a WinForm Form? Should I care?

• InvalidCastException when getting Text from a Label referenced by dynamicaly built String, Fix?

  - by Chris

  NET Version: 3.5 Ok, I recieve an error (System.InvalidCastException was unhandled. Message="Unable to cast object of type 'System.Windows.Forms.Control[]' to type 'System.Windows.Forms.Label'.") when trying to get Text from a Label referenced by a dynamicly built string. Here's my situation; I have an array of 250 labels named l1 - l250. What I want to do is loop through them using this while statement: int c = 1; while (c < 251) { string k = "l" + c.ToString(); //dynamic name of Control(Label) object ka = Controls.Find(k, true); string ct = ((Label)ka).Text; //<<Error Occurs Here build = build + ct; c++; } and get the text value of each to build a string named build. I don't get any build errors, just this while debuging. While debuging I can go down to view my local variables. When looking through these, I can view the contents of object ka; it does contain the correct Text value of the correct Label I want to "access". I just don't understand how to get there. The text value is listed under "[0]" which is the only subcatagory for "ka".

• Question about the evolution of interaction paradigm between web server program and content provider program?

  - by smwikipedia

  Hi experts, In my opinion, web server is responsible to deliver content to client. If it is static content like pictures and static html document, web server just deliver them as bitstream directly. If it is some dynamic content that is generated during processing client's request, the web server will not generate the conetnt itself but call some external proram to genearte the content. AFAIK, this kind of dynamice content generation technologies include the following: CGI ISAPI ... And from here, I noticed that: ...In IIS 7, modules replace ISAPI filters... Is there any others? Could anyone help me complete the above list and elabrate on or show some links to their evolution? I think it would be very helpful to understand application such as IIS, TomCat, and Apache. I once wrote a small CGI program, and though it serves as a content generator, it is still nothing but a normal standalone program. I call it normal because the CGI program has a main() entry point. But with the recenetly technology like ASP.NET, I am not writing complete program, but only some class library. Why does such radical change happens? Many thanks.

• Using memcache together with conventional cache

  - by Industrial

  Hi! Here's the deal. We would have taken the complete static html road to solve performance issues, but since the site will be partially dynamic, this won't work out for us. What we have thought of instead is using memcache + eAccelerator to speed up PHP and take care of caching for the most used data. Here's our two approaches that we have thought of right now: Using memcache on all<< major queries and leaving it alone to do what it does best. Usinc memcache for most commonly retrieved data, and combining with a standard harddrive-stored cache for further usage. The major advantage of only using memcache is of course the performance, but as users increases, the memory usage gets heavy. Combining the two sounds like a more natural approach to us, even though the theoretical compromize in performance. Memcached appears to have some replication features available as well, which may come handy when it's time to increase the nodes. What approach should we use? - Is it stupid to compromize and combine the two methods? Should we insted be focusing on utilizing memcache and instead focusing on upgrading the memory as the load increases with the number of users? Thanks a lot!

• JSF: Avoid nested update calls

  - by dhroove

  I don't know if I am on right track or not still asking this question. I my JSF project I have this tree structure: <p:tree id="resourcesTree" value="#{someBean.root}" var="node" selectionMode="single" styleClass="no-border" selection="#{someBean.selectedNode}" dynamic="true"> <p:ajax listener="#{someBean.onNodeSelect}" update=":centerPanel :tableForm :tabForm" event="select" onstart="statusDialog.show();" oncomplete="statusDialog.hide();" /> <p:treeNode id="resourcesTreeNode" > <h:outputText value="#{node}" id="lblNode" /> </p:treeNode> </p:tree> I have to update this tree after I added something or delete something.. But whenever I update this still its nested update also call I mean to say it also call to update these components ":centerPanel :tableForm :tabForm"... This give me error that :tableForm not found in view because this forms load in my central panel and this tree is in my right panel.. So when I am doing some operation on tree is it not always that :tableForm is in my central panel.. (I mean design is something like this only) So now my question is that can I put some condition or there is any way so that I can specify when to update nested components also and when not.... In nut shell is there any way to update only :resoucesTree is such a way that nested updates are not called so that I can avoid error... Thanks in advance.

• Enumerating pixel formats for adaptors and modes with OpenGL

  - by Robinson

  I'm trying to code an OpenGL path for my 3D engine. The D3D path enumerates all device adaptors, all modes (by mode I mean bit depth, dimensions, available windowed, and refresh rate) for each adaptor and then all pixel formats available for the given mode and adaptor, along side certain useful caps (shader version, filter types, etc.). So, I have broadly got the following protected functions in the class: // Enumerate all back/front buffer combinations. virtual void EnumerateBackFrontBufferCombinations(CComPtr<IDirect3D9>& d3d9); // Enumerate all depth/stencil formats. virtual void EnumerateDepthStencilFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all multi-sample formats. virtual void EnumerateMultiSampleTypes(CComPtr<IDirect3D9>& d3d9); // Enumerate all device formats, i.e. dynamic, static, render target, etc. virtual void EnumerateMapFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all capabilities. virtual void EnumerateCapabilities(CComPtr<IDirect3D9>& d3d9); The adaptors are enumerated with EnumDisplayDevices, the modes (resolutions and refresh rates) are enumerated with EnumDisplaySettings, so this can be done for either GL or D3D. The other functions I'm not so sure about with OpenGL. What are the equivalents to the IDirect3D9's CheckDeviceType, CheckDeviceFormat, CheckDeviceMultiSampleType, CheckDepthStencilMatch? I know I can use DescribePixelFormat, given a DC, but you kind-of need to have created the window before you can use a DC with it, but you can't create the window correctly until you know what formats you're going to use. Any tips you can give me? Thanks.

• Dealing with expired authentication for a partially filled form?

  - by aaronls

  I have a large webform, and would like to prompt the user to login if their session expires, or have them login when they submit the form. It seems that having them login when they submit the form creates alot of challenges because they get redirected to the login page and then the postback data for the original form submission is lost. So I'm thinking about how to prompt them to login asynchrounsly when the session expires. So that they stay on the original form page, have a panel appear telling them the session has expired and they need to login, it submits the login asynchronously, the login panel disapears, and the user is still on the original partially filled form and can submit it. Is this easily doable using the existing ASP.NET Membership controls? When they submit the form will I need to worry about the session key? I mean, I am wondering if the session key the form submits will be the original one from before the session expired which won't match the new one generated after logging in again asynchrounously(I still do not understand the details of how ASP.NET tracks authentication/session IDs). Edit: Yes I am actually concerned about authentication expiration. The user must be authenticated for the submitted data to be considered valid.

• Windows Azure - access webrole local storage from separate workerrole

  - by Brett Smith

  I'm running an application on windows azure, the MVC views need to be dynamic, I started by storing them as records in the database, but am quite keen to move them to a physical location. My concept was to create the physical file via code... which worked great and speeds up the page load dramatically. This was of course before I realised that the files were only available for the duration of the role Next I looked at a start up task to create the files when the role was started - however I then realised that any separate instances weren't going to sync up unless I monitored the database for changes. So I moved from a start up task to a function in the run method of the role that checks the database every 10 minutes to see if changes have occurred. The problem is that this seems to choke up the application (at least in the warm up stage). Ideally I would like to move the run function to it's own worker role that can sit there and push files out to web role instances, but I'm unsure on how I would go about accessing the web roles local storage from the worker role. Can anybody tell me whether this is actually possible? and hopefully point me in the right direction to achieve this? Just to clarify what I'm trying to achieve -View is created in user interface running on web role and stored in database -Separate web role (front end) has clientside application with virtualpath provider pointing Views requests to local storage (localresource) -separate worker role to create View structure and load this into clientside web role local storage
