Plzz help..... void CFileOpenDlg::OnBnClickedButton2() { // TODO: Add your control notification handler code here CRect r; CBitmap* m_bitmap; CDC dc, *pDC; BITMAP bmp; m_bitmap = new CBitmap(); m_bitmap-LoadBitmapW(IDB_BITMAP1); m_bitmap-GetBitmap(&bmp); pDC = this-GetDC(); dc.CreateCompatibleDC(pDC); dc.SelectObject(m_bitmap); pDC-BitBlt(200, 200, bmp.bmWidth, bmp.bmHeight, &dc,0 , 0, SRCCOPY); m_bitmap-DeleteObject(); m_bitmap-Detach(); } waiting for reply........**

  • How should I organize my mvc templates?

    - by CatZ
    Hi, In the new version of MVC we have been given display and editor templates. I was wondering how to make the best possible use of these. I was at first thinking in the line of creating one for a collection and one for an item in the case I want to display either as a list or single but it does not really make sense to me. I'll show you what I mean and please comment if this is wrong. I have trouble figuring it out myself. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<DisplayPhoneModel>>" %> <% foreach (var item in Model){%> <%= Html.DisplayFor(x => item) %> <%}%> So in my tiny reality that would for every item in the model search for a display template for DisplayPhoneModel. That display template could then simply look like. <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DisplayPhoneModel>" %> <%= Html.LabelFor(x => x.PhoneType) %>&nbsp;<%= Html.LabelFor(x => x.PhoneNumber) %> So, question is if there is a better way to handle this? Am I at all on the right path?

  • resolve snmp oids in perl

    - by Sec
    Is there a simple way/module to map snmp(MIB) strings to OIDs in perl? E.g. I start with "sysUpTime.0" and get "1.3.6.1.2.1.1.3.0". As far as I can see, Net::SNMP expects you to have them already mapped.

  • In .NET, how do I prevent, or handle, tampering with form data of disabled fields before submission?

    - by David
    Hi, If a disabled drop-down list is dynamically rendered to the page, it is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute. This code: protected override void OnLoad(EventArgs e) { var ddlTest = new DropDownList() {ID="ddlTest", Enabled = false}; ddlTest.Items.AddRange(new [] { new ListItem("Please select", ""), new ListItem("test 1", "1"), new ListItem("test 2", "2") }); Controls.Add(ddlTest); } results in this HTML being rendered: <select disabled="disabled" id="Properties_ddlTest" name="Properties$ddlTest"> <option value="" selected="selected">Please select</option> <option value="1">test 1</option> <option value="2">test 2</option> </select> The problem occurs when I use Firebug to remove the "disabled" attribute, and to change the selected option. On submission of the form, and re-creation of the field, the newly generated control has the correct value by the end of OnLoad, but by OnPreRender, it has assumed the identity of the submitted control and has been given the submitted form value. .NET seems to have no way of detecting the fact that the field was originally created in a disabled state and that the submitted value was faked. This is understandable, as there could be legitimate, client-side functionality that would allow the disabled attribute to be removed. Is there some way, other than a brute force approach, of detecting that this field's value should not have been changed? I see the brute force approach as being something crap, like saving the correct value somewhere while still in OnLoad, and restoring the value in the OnPreRender. As some fields have dependencies on others, that would be unacceptable to me.

  • 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".

  • Recommendations for a 3rd party Calendar picker class that's easy to use in iPhone/iPad apps

    - by BeachRunnerJoe
    Hello. I'd like to add a Calendar picker control to my iPad app that is similar in appearence and functionality to the Calendar picker control in the upper right corner of the native Calendar app on the iPad. I've looked into a couple of the 3rd party frameworks that have Calendar controls like this (such as the Tapku Library), but because I'm new to iPhone OS development, I'm having a hard time figuring out how to use them, mostly because the ones I've looked at have little or no documentation. For those that have used 3rd party Calendar picker controls, can you recommend one that is... Easy to use or provide decent enough documentation to figure out how to use it Legit for use in iPhone OS 3.2+ (including 4.0) Or if you could recommend one and provide some code snippets from your projects that show how to... Initialize and display it Retrieve the date selected by the user I would most greatly appreciate it and I'm sure there are many others that would as well (and would be happy to vote up your response)! Thank you very much in advance, I'm going to continue researching this question right now!

  • 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.

  • create a dict of lists from a string

    - by Chris Card
    I want to convert a string such as 'a=b,a=c,a=d,b=e' into a dict of lists {'a': ['b', 'c', 'd'], 'b': ['e']} in Python 2.6. My current solution is this: def merge(d1, d2): for k, v in d2.items(): if k in d1: if type(d1[k]) != type(list()): d1[k] = list(d1[k]) d1[k].append(v) else: d1[k] = list(v) return d1 record = 'a=b,a=c,a=d,b=e' print reduce(merge, map(dict,[[x.split('=')] for x in record.split(',')])) which I'm sure is unnecessarily complicated. Any better solutions?

  • Nhibernate: mapping two different properties between the same 2 entities

    - by Carlos Decas
    I have a Class A: public class ClassA { public int ID {get; private set;} public string Code {get; private set;} public ClassB B {get; private set;} public IList<ClassB> ListB {get; private set;} } And a ClassB: public class ClassB { public int ID {get; private set;} public string Code {get; private set;} public ClassA A {get; private set;} //some other attributes... } And the Mappings: public ClassAMap() { Table("ClassA"); Id(classA => classA .ID, "ID").GeneratedBy.Identity(); Map(classA => classA.Code, "Code").Unique().Not.Nullable(); //HERE IS THE PROBLEM: -------- References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); //----- HasMany(classA => classA.ListB).Table("ClassB").KeyColumn("IDClassA").AsBag().Not.LazyLoad().Inverse().Cascade.AllDeleteOrphan(); } ClassB Mappings: public ClassBMap() { Table("ClassB"); Id(classB => classB.ID).GeneratedBy.Identity(); References(classB => classB.A, "IDClassA").ForeignKey("ID").Cascade.SaveUpdate(); } The mappings for ListB in classA worked ok, because at first the was only ListB property and not B, when i had to map B i tried this: References(classA => classA.B,"IDClassB"); The mapping test failed because B wasn't saved, so i did this: References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); This time B was saved, but by saving B, classA was inserted two times, by A.B and by B.A. How can i solve this problem? Why does it work for the ListB property and not for the B property? Thanks

  • [Javascript] Linux Ajax (mootools Request.JSON) Header error

    - by VDVLeon
    Hi all, I use the following code to get some json data: var request = new Request.JSON( { 'url': sourceURI, 'onSuccess': onPageData } ); request.get(); Request.JSON is a class from Mootools (a javascript library). But on linux (ubuntu on firefox 3.5 and Chrome) the request always fails. So i tried to display the http request ajax is sending. (I used netcat to display it) The request is like this: OPTIONS /the+url HTTP/1.1 Host: example.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/532.3 (KHTML, like Gecko) Chrome/4.0.226.0 Safari/532.3 Referer: http://example.com/ref...

  • .NET consumer of ActiveX throwing TargetParameterCountException

    - by DevSolo
    I have a .NET (3.5 w/ Dev Studio 2008) app that hosts a visual Active X (written in C++ w/ Dev Studio 2003). Have access to all sources, but can't easily move the Active X control up to 2008. This as worked fine in the past. Made some changes to the Active X control and now, when calling one method on the Active X, I'm getting a TargetParameterCountException 100% of the time. The signature of the Active X method is: LONG CMyActive::License(LPCTSTR string1, LPCTSTR string2, LONG long1, LPCTSTR string3, LPCTSTR string4); When viewing the method in object browser of reflector, .NET sees it as: public virtual int License(string string1, string string2, int long1, string string3, string string4) I renamed the parameters for demonstration purpose (boss gets twitchy about any code). I left the method name, as it could be relevant. There are method calls prior that work. I just can't seen to figure out why I'm all of a sudden getting this exception. The HRESULT is 0x8002000e and a quick search seems to indicate that's a general one. Thanks to all for reading.

  • Is Accessing USB from web application for cross browser cross os possible at all ?

    - by Ved
    Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

  • Rackspace Cloud rewrite jpg causes Session reset

    - by willoller
    This may be the .Net version of this question. I have an image script with the following: ... Response.WriteFile(filename); Response.End(); I am rewriting .jpg files using the following rewrite rule in web.config: <rule name="Image Redirect" stopProcessing="true"> <match url="^product-images/(.*).jpg" /> <conditions> <add input="{REQUEST_URI}" pattern="\.(jp?g|JP?G)$" /> </conditions> <action type="Redirect" redirectType="SeeOther" url="/product-images/ProductImage.aspx?path=product-images/{tolower:{R:1}}.jpg" /> </rule> It basically just rewrites the image path into a query parameter. The problem is that (intermittently of course) Mosso returns a new Asp Session cookie which breaks the whole world. Directly accessing a static .jpg file does not cause this problem. Directly accessing the image script does not cause it either. Only rewriting a .jpg file to the .aspx script causes the Session loss. Things I have tried (From the Rackspace doc How can I bypass the cache?) I added Private cacheability to the image script itself: Response.Cache.SetCacheability(HttpCacheability.Private); I tried adding these cache-disabling nodes to web.config: <staticContent> <clientCache cacheControlMode="DisableCache" /> </staticContent> and <httpProtocol> <customHeaders> <add name="Cache-Control private" value="Cache-Control private" </customHeaders> </httpProtocol> The Solution I need The browser cache cannot be disabled. This means potential solutions involving Cache.SetNoStore() or HttpCacheability.NoCache will not work.

  • WPF drawing performance with large numbers of geometries

    - by MyFaJoArCo
    Hello, I have problems with WPF drawing performance. There are a lot of small EllipseGeometry objects (1024 ellipses, for example), which are added to three separate GeometryGroups with different foreground brushes. After, I render it all on simple Image control. Code: DrawingGroup tmpDrawing = new DrawingGroup(); GeometryGroup onGroup = new GeometryGroup(); GeometryGroup offGroup = new GeometryGroup(); GeometryGroup disabledGroup = new GeometryGroup(); for (int x = 0; x < DisplayWidth; ++x) { for (int y = 0; y < DisplayHeight; ++y) { if (States[x, y] == true) onGroup.Children.Add(new EllipseGeometry(new Rect((double)x * EDGE, (double)y * EDGE, EDGE, EDGE))); else if (States[x, y] == false) offGroup.Children.Add(new EllipseGeometry(new Rect((double)x * EDGE, (double)y * EDGE, EDGE, EDGE))); else disabledGroup.Children.Add(new EllipseGeometry(new Rect((double)x * EDGE, (double)y * EDGE, EDGE, EDGE))); } } tmpDrawing.Children.Add(new GeometryDrawing(OnBrush, null, onGroup)); tmpDrawing.Children.Add(new GeometryDrawing(OffBrush, null, offGroup)); tmpDrawing.Children.Add(new GeometryDrawing(DisabledBrush, null, disabledGroup)); DisplayImage.Source = new DrawingImage(tmpDrawing); It works fine, but takes too much time - 0.5s on Core 2 Quad, 2s on Pentium 4. I need <0.1s everywhere. All Ellipses, how you can see, are equal. Background of control, where is my DisplayImage, is solid (black, for example), so we can use this fact. I tried to use 1024 Ellipse elements instead of Image with EllipseGeometries, and it was working much faster (~0.5s), but not enough. How to speed up it? Regards, Oleg Eremeev P.S. Sorry for my English.

  • Silverlight performance with many loaded controls

    - by gius
    I have a SL application with many DataGrids (from Silverlight Toolkit), each on its own view. If several DataGrids are opened, changing between views (TabItems, for example) takes a long time (few seconds) and it freezes the whole application (UI thread). The more DataGrids are loaded, the longer the change takes. These DataGrids that slow the UI chanage might be on other places in the app and not even visible at that moment. But once they are opened (and loaded with data), they slow showing other DataGrids. Note that DataGrids are NOT disposed and then recreated again, they still remain in memory, only their parent control is being hidden and visible again. I have profiled the application. It shows that agcore.dll's SetValue function is the bottleneck. Unfortunately, debug symbols are not available for this Silverlight native library responsible for drawing. The problem is not in the DataGrid control - I tried to replace it with XCeed's grid and the performance when changing views is even worse. Do you have any idea how to solve this problem? Why more opened controls slow down other controls? I have created a sample that shows this issue: http://cenud.cz/PerfTest.zip UPDATE: Using VS11 profiler on the sample provided suggests that the problem could be in MeasureOverride being called many times (for each DataGridCell, I guess). But still, why is it slower as more controls are loaded elsewhere? Is there a way to improve the performance?

  • relative url in wcf service binding

    - by Jeremy
    I have a silverlight control which has a reference to a silverlight enabled wcf service. When I add a reference to the service in my silverlight control, it adds the following to my clientconfig file: <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_DataAccess" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:3097/MyApp/DataAccess.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_DataAccess" contract="svcMyService.DataAccess" name="BasicHttpBinding_DataAccess" /> </client> </system.serviceModel> </configuration> How do I specify a relative url in the endpoint address instead of the absolute url? I want it to work no matter where I deploy the web app to without having to edit the clientconfig file, because the silverlight component and the web app will always be deployed together. I thought I'd be able to specify just "DataAccess.svc" but it doesn't seem to like that.
